DETAILED DESCRIPTION
[0021] Bridges and similar mechanisms are commonly used to cross
gaps or traverse over undesirable terrain (e.g., rivers, cliffs,
etc.). While effective, bridges can take considerable time,
planning, and resources to construct. In instances where a bridge
is anticipated to be used for many years, expending the time and
resources toward constructing the bridge is usually
justifiable.
[0022] However, in some instances such as military operations, a
bridge may see limited use (e.g., the bridge is used a few times to
move a forward operating base from one area to another), or
multiple bridges may be needed during the course of the military
operation. In such instances, expending time, planning, and
resources to build a permanent bridge becomes inefficient and/or
undesirable. Moreover, if the military operation is in hostile
territory, there is an added risk of personnel being attacked while
constructing the bridge.
[0023] Accordingly, aspects of the present disclosure are directed
toward a lightweight, rapidly-deployable platform solution that can
serve as a bridge or deck for gap crossing. In various
implementations, the platform panels include integrated hardpoints
and recessed pockets for attachment to underlying structures.
Moreover, in multiple configurations, the platform panels can fold
or stack "accordion style" to stow and deploy for easier transport
as described in greater detail herein.
[0024] Platform Panel
[0025] Referring to the figures, and particularly FIG. 1, a
platform panel 100 is disclosed. The platform panel 100 comprises a
core 102 having a top surface 104 and a bottom surface 106.
[0026] The core 102 may comprise a single material or a combination
of materials such as carbon fiber, fiberglass, fiberglass
reinforced resin, foam (e.g., polymer foam), honeycomb material,
polyethelene teraphalate (PET), metals, wood, stiffening materials,
etc. Moreover, the core 102 may vary in thickness depending on user
needs and materials that are used. Preferably, materials that have
a high strength to weight ratio (i.e., high strength and low
weight), are utilized for the core 102. Materials such as aluminum,
while functional, may be heavier than desired for users that are
moving multiple platform panels with frequency.
[0027] Moreover, the platform panel 100 comprises a composite skin
disposed on the top surface 104 and the bottom surface 106 of the
core 102. In FIG. 1, the composite skin completely covers the top
surface 104 of the core 102. The composite skin can be made from a
variety of materials such as carbon fiber, fiberglass, fiberglass
reinforced resin, etcetera.
[0028] In various embodiments, the composite skin on the top
surface 104 of the core 102 has a thickness greater than the
composite skin on the bottom surface 106 of the core 102 to account
for compressive forces and other external forces such as vehicles
and/or personnel that traverse over the platform panel 100.
Moreover, in addition to (or alternative to) the composite skin
varying in thickness, the composite skin may also vary in
uniformity.
[0029] In multiple examples, the composite skin has non-uniform
thickness to increase surface area or provide more traction (or
"grip") for vehicles and/or personnel traversing over the platform
panel 100. For instance, the composite skin may form undulations.
In other implementations, grip tape or similar mechanisms can be
added to the top surface 104 of the core 102 for enhanced traction.
Moreover, the skin on a bottom of the panel may be nonuniform.
[0030] In various embodiments, the platform panel 100 further
comprises a rigid frame 108 disposed around a periphery of the core
102 as shown in FIG. 1. The rigid frame 108 provides increased
protection and durability for the core 102. The rigid frame 108 can
be made from various polymers (e.g., plastics, resins such as
polyethelene teraphalate, etc.), metals (e.g., aluminum), fiber
reinforced foam, carbon fiber reinforcement in a polymer matrix, or
a combination thereof.
[0031] The rigid frame 108 may further comprise various hardpoints
110 that provide numerous functions. For example, the hardpoints
110 may be used to move or maneuver the platform panel 100. In
addition, the hardpoints can be used to serve as an anchor or
tie-down point for mechanical attachments to secure the platform
panel 100 to another structure (e.g., feeding rope or webbing
through the hardpoint 110 to connect to a cross-beam).
[0032] In this regard, the platform panel 100 may also utilize a
recessed pocket 112 disposed on the top surface 104 of the core
102, which includes one or more fastener ports 114 disposed within
the recessed pocket 112. Examples of fasteners that are suitable
for use in conjunction with the fastener port include, but are not
limited to clamps, over-center latches, J-hooks, locks (e.g., twist
locks, cam locks, lever locks, etc.), ratchets, etc.
[0033] The recessed pocket 112 provides numerous benefits. For
instance, the recessed pocket 112 allows a user of the platform
panel 100 to fasten the platform panel 100 to an underlying
structure (e.g., support structures, suspension structures (e.g.,
I-beam, rails, etc.), etc.) without the fastener sticking out above
the top surface 104.
[0034] Having the fastener disposed within the recessed pocket 112
minimizes, or even eliminates, the possibility of a fastener
creating a road hazard that may damage vehicles passing over the
platform panel. Having the fastener disposed within the recessed
pocket 112 also allows users to deploy or lay an additional layer
or surface (e.g., sheet metal, asphalt, etc.) without being
obstructed by the fastener.
[0035] The recessed pocket 112 also provides a larger area for more
complex and/or larger fasteners (or coupling members) to be used
without being a road hazard as described herein.
[0036] In addition, the recessed pocket 112 and fastening port 114
also allows users to re-use fasteners without damaging the platform
panel 100. In existing solutions, fasteners such as screws, nails,
rivets, etc. are punched through platforms to secure the platform
to the underlying structure, thus causing damage to the
platform.
[0037] Conversely, the recessed pocket 112 and fastening port 114
allow users to use non-damaging fasteners and couplers (e.g.,
ratchets, clamps, etc.) without damaging the platform panel 100,
thus increasing longevity of the platform panel as well as
minimizing time spent deployment/stowing the platform panel
100.
[0038] FIG. 1 also illustrates a first hinge member 116 and a
second hinge member 118 disposed on opposing sides of the platform
panel 100. In various embodiments, the first hinge member 116
comprises a spacer, whereas the second hinge member 118 does not
have a spacer as described in greater detail herein.
[0039] In multiple implementations, the platform panel 100 further
comprises a receiving port 120 for attachment to an adjacent panel
(e.g., another platform panel, or a ramp panel as described in
greater detail herein). In multiple implementations, the receiving
port 120 is a hollow hardpoint (similar to the hardpoints in the
frame discussed above). In some such implementations, the hollow
hardpoint allows a fastener (such as a solid pin) to have a small
degree of freedom (or "play") to allow panels into interconnect at
various angles.
[0040] In multiple embodiments, more than one receiving port 120 is
used as indicated by the boxes in dashed lines. In this regard, not
all platform panels disclosed herein utilize a receiving port 120.
In various embodiments, only platform panels that couple to ramp
panels utilize a receiving port 120 as described in greater detail
herein.
[0041] FIG. 2 illustrates an example of two platform panels 100a
and 100b (from left to right respectively) that are coupled
together by a first hinge member 116 and a second hinge member 118.
Here, platform panel 100a includes a spacer 122 disposed between
the first hinge member 116 and the platform panel 100a.
[0042] Conversely, the platform 100b does not have a spacer between
the second hinge member 118 and the platform 100b. The spacer 122
compensates for an offset "O" created by coupling the platform
panel 100a to the platform panel 100b via the first hinge member
116 and the second hinge member 118 as shown in FIG. 2.
Positionally, the spacers 122 alternate between opposing sides of a
platform panel (e.g., platform panel 100a) on each subsequent
platform panel (e.g., left side of panel 100a has a spacer, left
side of platform panel 100b, which is adjacent to platform panel
100a, does not have a spacer, etc.).
[0043] Without the spacer 122 compensating for the offset "0", a
series of platform panels (e.g., 100a, 100b, 100c, . . . 100n)
would zip-zag or stagger from one another when deployed (i.e., the
series of panels would not deploy in a straight line), which can
lead to other complications. While the hinge members 116 and 118
can utilize various geometries, the geometry shown in FIGS. 1 and 2
allows platform panels to rapidly stow and deploy as described in
greater detail herein.
[0044] In various embodiments, the first hinge member 116 and/or
the second hinge member 118 further comprise a cut-out portion 124
(e.g., flutes, channels, etc.) for weight reduction.
[0045] Now referring to FIG. 3A, a bottom-up view of an example
platform panel 300 is illustrated. The platform panel 300 can
either be a stand-alone embodiment, or a variant of the platform
panel 100. Therefore, embodiments and variations may be shared. As
such, like features and elements share like numbers, except that
features and elements of FIG. 3A are numbered 200 higher (e.g.,
hardpoint 310 is analogous to hardpoint 110, unless stated
otherwise).
[0046] The platform panel 300 comprises a positioner 330 coupled to
the bottom surface 306 of the core 302. The positioner 330 acts as
a barrier that prevents structures from encroaching a center line
"C" of the platform panel 300.
[0047] For instance, if the platform panel 300 is deployed over a
first support structure "SS1" and a second support structure "SS2",
both of which are capable of lateral movement toward the center
line "C", the positioner 330 may prevent the first support
structure "SS1" and the second support structure "SS2" from getting
too close to the center line "C", which may cause instability.
Moreover, the positioner 330 also aids in maintaining the platform
panel 300 in a desired orientation and further stabilizes the
platform panel 300.
[0048] In embodiments associated with FIG. 3A, the positioner 330
acts as a guide or "bumper" that keeps the platform panel 300
within the support structures SS1 and SS2.
[0049] In various embodiments, the positioner 330 can be locked in
place (e.g., by a nylon lock nut) when stowed, and selectively
released (e.g., by a quick-release pin). In various embodiments,
the positioner 330 the positioner hingedly swings (e.g., via
hinges) toward an outside edge of the core 302.
[0050] In yet further embodiments, the positioner 330 can be
tethered to the platform panel 300 so that the positioner 330 does
not exceed a predefined rotation or travel distance (e.g.,
positioner is tethered to panel to prevent over-rotation beyond
90.degree.).
[0051] Now referring to FIG. 3B, a bottom-up view of another
example platform panel 300 is illustrated. The platform panel 300
can either be a stand-alone embodiment, or a variant of the
platform panel 100. Therefore, embodiments and variations may be
shared. As such, like features and elements share like numbers,
except that features and elements of FIG. 3B are numbered 200
higher (e.g., hardpoint 310 is analogous to hardpoint 110, unless
stated otherwise).
[0052] In FIG. 3B, a positioner 340 is disposed on the bottom
surface 306 of the platform panel 300. In various embodiments, the
positioner 340 guides the platform panel 300 along SS1 and SS2. In
multiple implementations, the positioner 340 is an "L" shape, or a
hook shape that goes under or around SS1 and SS2. In other
implementations, the positioners 340 act as bumpers that butt
against SS1 and SS2.
[0053] Now referring to FIG. 3C, a bottom-up view of yet another
example platform panel 300 is illustrated. The platform panel 300
can either be a stand-alone embodiment, or a variant of the
platform panel 100. Therefore, embodiments and variations may be
shared. As such, like features and elements share like numbers,
except that features and elements of FIG. 3C are numbered 200
higher (e.g., hardpoint 310 is analogous to hardpoint 110, unless
stated otherwise).
[0054] FIG. 3C briefly illustrates an interaction between support
structures (e.g., SS1 and SS2) and the fastener ports 314. Here, a
re-usable fastener 350 (e.g., ratchet, or clamp) is fed through the
fastener port 314 and engages SS1 and SS2. When a user needs to
stow or remove the platform panel 300, the user can simply
disengage the re-usable fastener 350 and pull it back through the
fastener port 314.
[0055] In FIG. 4, a series of platform panels 400a, 400b, 400c,
400d, 400e, and 400f is illustrated in a partially deployed state.
The disclosures with respect to FIG. 4 can either be a stand-alone
embodiment, or a variant of any platform panel disclosed herein.
Therefore, embodiments and variations may be shared across
apparatuses.
[0056] As the series of platform panels begin deployment,
subsequent platform panels, which are connected via hinge members
(see e.g., 114 and 166 in FIG. 1), begin deployment as well. In
FIG. 4, deployment begins with platform panel 400a (e.g., by a user
that uses a tether looped through hardpoint 410 (see hardpoint 110
in FIG. 1 or hardpoint 310 in FIG. 3) as indicated by the solid
arrow. As deployment continues, platform panel 100b follows after
platform 100a, platform panel 400c follows platform panel 400b, and
so on.
[0057] Reference numbers 406a and 406b, which are bottom surfaces
of the platform panel 100a and 100b respectively, are shown for
context.
[0058] Correspondingly, the series of platform panels can be stowed
by reversing deployment, which results in a compact or stowed
configuration illustrated by platform panels 400c, 400d, 400e, and
400f. In various embodiments, the series of platform panels can be
retracted or stowed by using a winch or ratchet that connections to
one or more hardpoints (e.g., 410a). While each panel within the
series of panels is illustrated with hardpoints, in practice,
hardpoints may be limited to specific panels (e.g., every other
panel, patterned (every other adjacent panel has hardpoints that
are adjacent to one another), etc.).
[0059] The stowed configuration illustrated in FIG. 4 has numerous
advantages. For instance, the stowed configuration has a reduced
physical footprint (i.e., takes up less overall space). Moreover,
the stowed configuration allows each platform panel within the
series of platform panels to remain coupled together, thus reducing
time and labor costs when deploying, stowing, and transporting the
series of platform panels.
[0060] In an alternative configuration, the series of platform
panels can be deployed or "rolled" off of a barrel or spool. In
another alternative configuration, the series of platform panels
slide or telescope to deploy. In multiple implementations,
deployment of the series of platform panels is done
autonomously.
[0061] Aspects of the present disclosure also contemplate
integrating a truss or railing system that deploys with the series
of platform panels.
[0062] Ramp Panel
[0063] In addition to platform panels as disclosed herein, aspects
of the present disclosure include one or more ramp panels that
serve as transitions between a ground surface and a corresponding
platform panel.
[0064] Now referring to FIG. 5, a ramp panel 500 is illustrated.
The ramp panel 500 comprises a core 502 having a top surface 504
and a bottom surface 506. Moreover, the ramp panel 500 comprises a
composite skin disposed on the top surface 504 and the bottom
surface 506 of the core 502.
[0065] In this regard, the core 502 and composite skin of the ramp
panel 500 are analogous to cores and composite skins as described
herein (e.g., core 102 in FIG. 1). However, in various embodiments,
the core 502 of the ramp panel 500 has a different composition or
ratio of materials to account for differences in function when
compared to a platform panel. For example, in various embodiments,
the composite skin on the top surface 504 of the core 502 has a
thickness greater than the composite skin on the bottom surface 506
of the core 502.
[0066] In other instances, the core 502 of the ramp panel 500 may
have a greater thickness than that of the platform panel. Moreover,
the core 502 of the ramp panel 500 may use compositional materials
at higher densities, thus making the core 502 more stiff and/or
rigid. In yet another instance, the core 502 may be constructed so
that the core 502 bends under pressure, as opposed to compressing
under pressure as is the case with some platform panels described
herein (i.e., bending action vs compressive action).
[0067] Further, the ramp panel 500 comprises a connection edge 508
coupled to the core 502, wherein the connection edge 508 comprises
a member that fastens to an adjacent panel as described in greater
detail herein. In multiple embodiments, the member is an extruded
pin.
[0068] Yet further, the ramp panel 500 comprises a beveled edge 510
that opposes the connection edge 508, wherein when in use, the
beveled edge 510 rests on a ground surface.
[0069] In multiple examples, the composite skin has non-uniform
thickness to increase surface area or to provide more traction (or
"grip") for vehicles and/or personnel traversing over the ramp
panel 500. For instance, the composite skin may form undulations.
In other implementations, grip tape or similar mechanisms can be
added to the top surface 504 of the core 502 for enhanced
traction.
[0070] Now referring to FIG. 6, a close-up view of the connection
edge 508 of the ramp panel 500 is illustrated. Here, the connection
edge 508 comprises two members 512 that fasten to adjacent panels
(e.g., the receiving port 120 of the platform panel 100 in FIG. 1).
While the members 512 are shown as two pins, in practical
application more or fewer pins could be used, or a different type
of fastener may be used altogether. In multiple embodiments, the
connection edge 508 is selectively removable from the core 502,
which allows users to swap out one type of fastening member (e.g.,
the extruded pins) for another as described in greater detail
herein. For example, the two pins can be swapped for hooks,
threaded bolts, etc.
[0071] One advantage of a removable (or swappable) connections edge
508 is that the ramp panel 500 can be adapted to accommodate
various ground angles that a user may encounter. Moreover,
different fasteners are better suited for more demanding loads.
Thus, a swappable connection edge 508 that uses different fasteners
may be beneficial.
[0072] In FIG. 6, screws/rivets 514 are used to fasten the
connection edge 508 to the core 502, but virtually any type of
fastener would suffice.
[0073] Bridge Deck Assembly
[0074] FIG. 7 illustrates an example embodiment of a bridge deck
assembly 700 (or "bridge assembly 700" for shorthand). The bridge
assembly 700 may utilize one or more variations of the platform
panels and ramp panels as described herein. Accordingly, the bridge
assembly 700 may incorporate embodiments and disclosures of ramp
panels and platform panels herein.
[0075] In FIG. 7, a bridge assembly 700 spans from one ground
surface "GS1" to another ground surface "GS2" over a spatial gap
"SG". The bridge assembly 700 comprises a first ramp panel 702. The
first ramp panel 702 comprises a first core 704 having a top
surface 706 and a bottom surface (obscured by view). The first ramp
panel 702 further comprises a composite skin disposed on the top
surface 706 and the bottom surface of the first core 704. In
various embodiments, the composite skin on the top surface 706 of
the first core 704 has a thickness greater than the composite skin
on the bottom surface of the first core 704.
[0076] Moreover, the first ramp panel comprises a connection edge
708 coupled to the core 704, wherein the connection edge 708
comprises members 710 (see. e.g., fasteners 512 in FIG. 5) that
fasten to an adjacent panel.
[0077] Yet further, the first ramp panel 702 comprises a beveled
edge 712 that opposes the connection edge 708, wherein when in use,
the beveled edge 712 rests on a ground surface (e.g., GS1). In
various embodiments, the first ramp panel 702 further comprises a
first grip member 714 (e.g., grip tape) or a similar mechanism to
increase traction on the top surface 706 of the first core 704.
[0078] The bridge assembly 700 further comprises a second ramp
panel 716. The second ramp panel 716 is analogous to the first ramp
panel 702. In this regard, the second ramp panel 716 comprises a
second core 718 having a top surface 720 and a bottom surface
(obscured by view). The second ramp panel 716 further comprises a
composite skin disposed on the top surface 720 and the bottom
surface of the second core 718. In various embodiments, the
composite skin on the top surface 720 of the second core 718 has a
thickness greater than the composite skin on the bottom surface of
the second core 718.
[0079] Moreover, the second ramp panel 716 comprises a connection
edge 722 coupled to the second core 718, wherein the connection
edge 722 comprises members 724 that fasten to an adjacent panel. In
addition, the second ramp panel 716 comprises a beveled edge 726
that opposes the connection edge 722, wherein when in use, the
beveled edge 726 rests on a ground surface (e.g., GS2). In various
embodiments, the second ramp panel 716 further comprises a second
grip member 728 (e.g., grip tape) or a similar mechanism to
increase traction on the top surface 720 of the second ramp panel
716.
[0080] The bridge assembly 700 also comprises a platform panel 730
disposed between the first ramp panel 702 and the second ramp panel
716. The platform panel 730 comprises a third core 732 having a top
surface 734 and a bottom surface (obscured by view), and a
composite skin disposed on the top surface 734 and the bottom
surface of the third core 732.
[0081] Moreover, the platform panel 730 comprises a positioner
(obscured by view, but is analogous to positioner 330 in FIG. 3)
coupled to the bottom surface of the third core 732.
[0082] Yet further, the platform panel 730 comprises a first set of
ports 736 that receive the members 710 from the first ramp panel
702. In addition, the platform panel 730 comprises a second set of
ports 738 that receive the members 724 from the second ramp panel
716. While the first set of ports 736 and the second set of ports
738 are illustrated in pairs, in practical application the first
set of ports 736 and/or the second set of ports 738 may be
implemented as a single port, three ports, slots, or any other
suitable coupler, fastener, port, etc.
[0083] In various embodiments, the platform panel 730 further
comprises a recessed pocket 740 disposed on the top surface 734 of
the third core 732, and a fastening port 742 disposed within the
recessed pocket 740.
[0084] Aspects of the present disclosure also contemplate
embodiments of a bridge assembly that comprise two or more platform
panels as illustrated in FIG. 8. The disclosures herein with
respect to FIG. 8 can either be a stand-alone embodiment, or a
variant of the bridge assembly 700 disclosed herein. As such, like
features and elements share like numbers, except that features and
elements of FIG. 8 are numbered 100 higher. Therefore, embodiments
and variations may be shared.
[0085] In FIG. 8, the platform panel 730 (hereinafter "first
platform panel") further comprises a first hinge member 744
disposed on a first side of the first platform panel 730, wherein
the first hinge member 744 comprises a first spacer 746. Moreover,
the platform panel 730 further comprises a second hinge member 748
disposed on an opposing side of the first platform panel 730 in
relation to the first hinge member 744, wherein the second hinge
member 748 does not have a spacer.
[0086] In addition, the bridge assembly 700 comprises a second
platform panel 750 disposed between the first ramp panel 702 and
the second ramp panel 716. The second platform panel 750 is
analogous to the first platform panel 730, except that hinges
disposed on the second platform panel 750 oppose hinge members of
the first platform panel 730 as described herein.
[0087] In this regard, the second platform panel 750 comprises a
third hinge member 752 disposed on a first side of the second
platform 750, wherein the third hinge 752 member does not have a
spacer. In addition, the second platform panel comprises a fourth
hinge member 754 disposed on an opposing side of the second
platform panel 750 in relation to the third hinge member 752,
wherein the fourth hinge member 754 comprises a second spacer
756.
[0088] When in use, the first hinge member 744 is adjacent to the
third hinge member 752, and the second hinge member 748 is adjacent
to the fourth hinge member 754, thereby positioning the first
spacer 746 on an opposing side of the bridge assembly 700 in
relation to the second spacer 756.
[0089] In various embodiments, the second platform panel 750
further comprises a second positioner (obscured by view, but see
e.g., positioner 330 in FIG. 3). All remaining reference numbers
and markers are shown for context. Reference numbers that were
shown in FIG. 7 that are not present in FIG. 8 were omitted for
visual clarity unless stated otherwise.
[0090] The bridge deck assembly 700 in FIGS. 7 and 8 represent just
a few of many possible configurations. For example, the bridge
assembly 700 may comprise three or more panels. In various
implementations, the ramp panels (e.g., 702 and 716) may be divided
into two or more sub panels that can be laterally adjusted to
accommodate a predefined width of a vehicle or personnel crossing
over the bridge assembly 700 as shown in FIG. 8. Ramp panel 702 has
been divided into 702a and 702b and ramp panel 716 has been divided
into 716a and 716b. The remaining reference numbers (e.g., 710a and
710b) are shown for context.
[0091] Depending on material composition and an amount of platform
panels used, various embodiments of the bridge assembly 700 can
support vehicles up to 4,600 pounds (.about.20,865 kg) over a
distance of 36 feet (11 meters), while the bridge assembly 700
itself weighs less than 600 pounds (.about.272 kg).
[0092] While the bridge assembly 700 in FIGS. 7 and 8 is shown in
isolation when deployed over the spatial gap ("SG"), aspects of the
present disclosure also contemplate use of the bridge assembly with
a spanning member or support structure (see. SS1 and SS2 in FIG.
3). For example, the bridge assembly 700 can be deployed over
and/or coupled to air beams, steel support beams, wooden support
beams, matted on ground, a scissor lift, a cable support, or a
combination thereof.
[0093] Bridge Assembly
[0094] FIGS. 9-11 illustrate a bridging assembly. Turning now to
FIG. 9, an inflatable bridging structure 900 without any panels
coupled to it is shown. In the embodiment of FIG. 9, a first
spanning member 902 and a second spanning member 904 are inflatable
rails that can span a longer distance than panels alone. The first
spanning member 902 and the second spanning member 904 maintain a
desired distance 906 from each other (within an acceptable
tolerance) by using separators 908, 910, 912 to ensure that the
spanning members 902, 904 do not separate by more than the desired
distance. The desired distance is based on panels, described above,
that will be coupled to the spanning members to create the full
bridging assembly as shown in FIG. 10.
[0095] With continued reference to FIG. 9, a retaining mechanism
914 that spans from one end of the bridging assembly to the other
end of the bridging assembly 900 ensures that the spanning members
902, 904 are arched to provide support for a load on the bridging
assembly 900 when the bridging assembly 900 is deployed. In the
embodiment of FIG. 9, the retaining mechanism 914 comprises two
runners (e.g., cables, straps, etc.) 916, 918; however, any
retaining mechanism 914 will suffice. In general, the retaining
mechanism 914 should be shorter than the spanning members 902, 904
to cause the spanning members 902, 904 to arch. While the spanning
members are shown as inflatable in the embodiment of FIG. 1, the
spanning members may be beams of metal, wood, concrete, composite,
or a combination thereof.
[0096] Turning now to FIG. 10, the bridging assembly 900 of FIG. 9
is shown with panels described above coupled to the bridging
assembly. In the embodiment shown, several deck panels 1002, 1004,
1006 are coupled to the spanning members 902, 904 via straps 1010,
1012, 1014 to provide a load-bearing surface 1016. Further, ramp
panels 1018, 1020 are coupled to a first panel 1002 of the deck
panels (as discussed in reference to FIG. 6) to allow a load to get
onto the load-bearing surface 1016. For example, if the load is a
vehicle, the vehicle can drive up the ramp panels to get to the
load-bearing surface.
[0097] Turning now to FIG. 11, a coupling mechanism 1100 is shown
for coupling the panels 1002 to the spanning members 902. The
coupling mechanism is bolted to the deck panel 1002 and extends
through a port 1102 in the deck panel (as discussed above, e.g.,
the fastener ports 114 of FIG. 1). The coupling mechanism 1100
includes a release 1104 and a hook 1106. As discussed above, a
strap 1108 (e.g., 1010, 1012, etc. of FIG. 10) of the bridging
assembly secures the panel 1002 to the spanning members 902 via the
hook 1106. In other words, while the panel is coupled to the
spanning member, the coupling is not permanent. Instead, the panel
can easily be uncoupled from the spanning member to store for a
later use.
[0098] Other features may be added to the bridging system as well.
For example, the bridging system may include guard rails, guide
posts, reflectors, chain guides, rope guides, drain holes, fluid
channels, trusses, or combinations thereof. Further, the panels
used for a bridging system may include uniform cores or nonuniform
cores.
[0099] As can be seen, with the assemblies, panels, and systems
described herein, a bridge may be deployed quickly cross a span:
inflate spanning members, couple panels to spanning members using
the hooks and straps (minimal tools required), move bridging
assembly to cover the span, cross the span, remove panels, deflate
spanning members, and store for later use.
