Description
TECHNICAL FIELD
[0001] The present invention relates to a single-lip channel steel
bar, and more particularly, to a novel improvement for enhancing
drainage of a rack in a case where a single-lip channel steel bar
is used as a transverse beam or/and a longitudinal beam and a
flat-plate-like solar panel module or the like is placed on the
transverse beam.
BACKGROUND ART
[0002] As this type of lipped channel steel bars that have been
conventionally used, configurations disclosed in Patent Literatures
1 and 2 can be exemplified. The lipped channel steel bars have
double-lip configurations. For example, as illustrated in FIGS. 30
to 33, a solar panel module 1 is placed on transverse beams 2, and
the transverse beams 2 are provided, through the intermediation of
longitudinal beams 3 disposed so as to be orthogonal to the
transverse beams 2, on pillars 5 provided on base members 4.
[0003] Therefore, for example, the solar panel module 1, which is

SUMMARY OF INVENTION
Technical Problems
[0006] The conventional lipped channel steel bars are configured as
described above, and hence have the following problems.
[0007] That is, as is apparent from the configurations illustrated
in FIGS. 30 and 33, the solar panel module is inclined, and thus
the transverse beams 2 are also inclined. As is apparent
particularly from the configurations illustrated in FIGS. 30 and
31, the transverse beams 2 themselves have double-lip shapes, and
hence the transverse beams 2 have a large load capacity and are
less likely to bend. Regarding each transverse beam 2 disposed in
an inclined posture, the transverse beam 2 has a double-lip shape,
and hence rainwater 6 and the like coming from an outside are
collected on an inner side of a lower lip 2a in a case where the
transverse beam 2 is inclined downward as illustrated in FIGS. 30
and 31. As a result, the transverse beam 2 is reduced in strength
due to rust and the like, and hence has a problem in
durability.

Advantageous Effects of Invention
[0009] The single-lip channel steel bar according to the present
invention is configured as described above, and hence can provide
the following effects.
[0010] That is, the single-lip channel steel bar includes: the
channel steel bar body having a longitudinal shape and a grooved
cross-sectional shape; the first side plate and the second side
plate formed on both the side portions of the back plate of the
channel steel bar body, respectively; the lip formed at the end
portion of the first side plate and protruding toward the second
side plate; and only the flat surface portion formed at the end
portion of the second side plate. The second side plate is formed
of the right-angled plate extending in the right-angled direction
orthogonal to the plate height direction of the back plate, or of
the non-right-angled plate extending in the non-right-angled
direction inclined at 90 degrees or more with respect to the plate
height direction of the back plate. The single-lip channel steel
bar serves as the transverse beam or the longitudinal beam.
Accordingly, all water falling onto the transverse beam flows
downward from the second side plate, and thus is not collected. As
a result, no rust occurs, and durability can be ensured for a long
period of time.
[0011] Further, the transverse beam includes the single-lip channel
steel bar according to claim 1. The transverse beam is disposed on
the longitudinal beam so as to be orthogonal to the longitudinal
direction of the longitudinal beam, and the solar panel module
having a plate-like shape is provided on the transverse beam,
thereby disposing the longitudinal beam, the transverse beam, and
the solar panel module in the horizontal posture or the inclined
posture. Accordingly, the solar panel module can be supported for a
long period of time.
[0012] Further, the transverse beam includes the single-lip channel
steel bar according to claim 1 including the second side plate that
is formed of the right-angled plate extending in the right-angled
direction orthogonal to the plate height direction of the back
plate, and the transverse beam is provided on the longitudinal beam
that is disposed in the inclined posture. Accordingly, water can be
completely drained away from the second side plate.
[0013] Further, the transverse beam according to claim 1 includes
the second side plate extending in the non-right-angled direction
inclined at 90 degrees or more with respect to the plate height
direction of the back plate, and in order to incline the second
side plate downward, the transverse beam is provided, through the
intermediation of the inclined member having a wedge shape, on the
longitudinal beam disposed in the horizontal posture. Accordingly,
the second side plate is inclined downward, and hence water can be
completely drained out of both the transverse beam and the
longitudinal beam.
[0014] Further, the longitudinal beam according to claim 1 includes
the second side plate extending in the non-right-angled direction
inclined at 90 degrees or more with respect to the plate height
direction of the back plate, and the longitudinal beam is provided
on the base member through the intermediation of the inclined
member having a wedge shape. The transverse beam according to claim
1 includes the second side plate extending in the non-right-angled
direction inclined at 90 degrees or more with respect to the plate
height direction of the back plate, and the transverse beam is
provided on the longitudinal beam through the intermediation of the
inclined member. Accordingly, even when the second side plate of
each of the beams is inclined in the non-right-angled direction,
the inclined member having a wedge shape is used, and thus it is
possible to combine the transverse beam and the longitudinal beam
in a right-angled manner, and to obtain a rack capable of achieving
complete drainage.

DESCRIPTION OF EMBODIMENTS
[0048] The present invention has an object to provide a single-lip
channel steel bar capable of enhancing drainage of each rack in a
case where the single-lip channel steel bar is used as a transverse
beam or a longitudinal beam and a flat-plate-like solar panel
module or the like is placed on the transverse beam.
Embodiments
[0049] In the following, single-lip channel steel bars according to
preferred embodiments of the present invention are described with
reference to the drawings.
[0050] Note that, the same or corresponding components as those of
the conventional example are denoted by the same reference symbols,
and description thereof is omitted.
[0051] Reference numeral 4 of FIG. 1 denotes base members.
Longitudinal beams 3 are supported in an inclined state on the base
members 4 through the intermediation of a plurality of pillars
5.
[0052] A plurality of transverse beams 2 are provided on each of
the longitudinal beams 3. Each of the transverse beams 2 has a
longitudinal direction "B" along a direction orthogonal to a
longitudinal direction "A" of each of the longitudinal beams 3.
[0053] On the transverse beams 2, a plate-like solar panel module 1
illustrated in FIG. 6 is fixed with an adhesive, or a fixing member
such as a bolt and a screw.
[0054] As illustrated in FIG. 2 in an enlarged manner, each
transverse beam 2 is formed of a single-lip channel steel bar
including a channel steel bar body 10 having a C-shape in overall
cross-sectional view. On both sides of a back plate 12 of the
transverse beam 2, a first side plate 14 including a lip 13, and a
right-angled plate 15 including no lip 13 are formed, respectively.
The right-angled plate 15 is formed only of a flat-plate-like flat
surface portion and forms a right angle with the back plate 12.
[0055] The right-angled plate 15 extends in a right-angled
direction orthogonal to a plate height direction 12a of the back
plate 12, and includes no lip 13. Accordingly, the right-angled
plate 15 is formed only of a flat plate so as to prevent formation
of puddles.
[0056] Note that, as illustrated also in FIG. 3, in a case where a
force indicated by an arrow C is applied to the transverse beam 2
and thus a load test is performed, the entire transverse beam 2
bends to a medium extent as indicated by a dotted line and a solid
line. Therefore, the transverse beam 2 has a sufficient load
capacity.
[0057] In addition, the longitudinal direction "A" of the
longitudinal beam 3 is oblique in FIG. 1, and hence even the same
double-lip channel steel bar as that used in the conventional
configuration is applicable as the longitudinal beam 3. However,
the single-lip channel steel bar of FIG. 2 having the same
configuration as that of the transverse beam 2 can be used as the
longitudinal beam 3.
[0058] Next, in a case of another embodiment of the present
invention illustrated in FIGS. 4 to 6, each longitudinal beam 3
provided on the base members 4 is disposed in a horizontal state,
and the plurality of transverse beams 2 are provided on the
longitudinal beam 3 so as to be orthogonal to the longitudinal beam
3. The solar panel module 1 is placed and provided on the
transverse beams 2.
[0059] Therefore, all of the longitudinal beams 3, the transverse
beams 2, and the solar panel module 1 provided on the base members
4 are disposed in a horizontal state, and the other structural
components are the same as those of the configuration illustrated
in FIGS. 1 to 3. Accordingly, herein, the same components are
denoted by the same reference symbols, and description thereof is
omitted.
[0060] Next, in a case of still another embodiment of the present
invention illustrated in FIGS. 7 to 10, the transverse beam 2 and
the longitudinal beam 3 each have a configuration different from
the configurations illustrated in FIGS. 1 to 6.
[0061] That is, as illustrated in FIGS. 7 to 10, the transverse
beam 2 is formed of a single-lip channel steel bar. As illustrated
in FIG. 9, the back plate 12, the first side plate 14, and the lip
13 are the same as those of the configuration illustrated in FIG.
1, but the second side plate 15 is formed of a non-right-angled
plate 15a. The non-right-angled plate 15a extends in a
non-right-angled direction inclined at 90 degrees or more with
respect to the plate height direction 12a of the back plate 12, and
is formed only of a flat surface portion that is inclined
downward.
[0062] Therefore, on each longitudinal beam 3 provided in a
horizontal posture on the base members 4 and having a longitudinal
shape, the transverse beams 2 are disposed in a horizontal posture.
On the transverse beams 2, the plate-like solar panel module 1 is
placed and disposed in a horizontal state.
[0063] The longitudinal beam 3 has the same structure as that of
the transverse beam 2. In a case where the longitudinal beam 3 is
placed on the base members 4, an inclined member 20 having a wedge
shape is interposed between the non-right-angled plate 15a and each
of the base members 4, and the inclined member 20 is interposed
also between the longitudinal beam 3 and the non-right-angled plate
15a of each of the transverse beams 2. In this manner, the solar
panel module 1, the transverse beams 2, and the longitudinal beams
3 can be disposed in a horizontal state on the base members 4.
[0064] The non-right-angled plate 15a of each of the beams 2, 3
extends to be inclined downward. Accordingly, for example, as
illustrated in FIG. 8, water is not collected on the
non-right-angled plate 15a and is completely drained away. As a
result, durability of each of the beams 2, 3 is significantly
enhanced.
[0065] Next, FIGS. 11 and 12 illustrate an assembly configuration
of each of the beams 2, 3 in a case where each of the beams 2, 3
illustrated in FIGS. 7 to 10 includes the non-right-angled plate as
the second side plate 15a.
[0066] That is, as illustrated in FIG. 11, the inclined member 20
is fitted onto an anchor bolt 21 of the base member 4, and the
longitudinal beam 3 is placed and fitted onto the anchor bolt
21.
[0067] Further, as illustrated in FIG. 12, the inclined member 20
is fitted onto a bolt 22 of the longitudinal beam 3 provided on the
base member 4, and the transverse beam 2 is laid on the inclined
member 20 and fitted onto the anchor bolt 22 through a hole 2a of
the transverse beam 2.
[0068] Therefore, according to the above-mentioned configuration,
the longitudinal beam 3 and the transverse beam 2 are arranged to
be orthogonal to each other and arranged to be stacked
vertically.
[0069] FIGS. 13 and 14 illustrate the configuration after
completion of assembly of the beams 2, 3 illustrated in FIG. 12.
FIG. 13 illustrates a lateral view of the transverse beam 2 that is
fastened with a nut 25. FIG. 14 illustrates a longitudinal view of
the transverse beam 2.
[0070] Note that, an inclined washer 30 and a nut 31 are used to
fix the longitudinal beam 3 as illustrated in FIG. 13, and the
inclined washer 30 is used to fix the transverse beam 2 as
illustrated in FIG. 14.
[0071] Next, configuration diagrams of FIGS. 15 to 29 illustrate
single-lip channel steel bars according to still other embodiments
of the present invention.
[0072] Note that, the same or corresponding components as those
used in the conventional example and the configurations illustrated
in FIGS. 1 to 14 are denoted by the same reference symbols, and
description thereof is omitted. Configurations illustrated in FIGS.
15 to 29 are different from the configurations illustrated in FIGS.
1 to 14 in that a protruding length of the second side plate 15 and
a protruding length of the second side plate 15a are smaller than
the protruding length used in the configuration illustrated in FIG.
2.
[0073] Reference numeral 4 of FIG. 15 denotes the base members. The
longitudinal beams 3 are supported in an inclined state on the base
members 4 through the intermediation of the plurality of pillars
5.
[0074] The plurality of transverse beams 2 are provided on each of
the longitudinal beams 3. Each of the transverse beams 2 has the
longitudinal direction "B" along the direction orthogonal to the
longitudinal direction "A" of each of the longitudinal beams 3.
[0075] On the transverse beams 2, the plate-like solar panel module
1 illustrated in FIG. 6 is fixed with an adhesive, or a fixing
member such as a bolt and a screw.
[0076] As illustrated in FIG. 16 in an enlarged manner, each
transverse beam 2 is formed of a single-lip channel steel bar
including the channel steel bar body 10 having an L-shape in
overall cross-sectional view. On one side portion of the back plate
12 of the transverse beam 2, the first side plate 14 including the
lip 13 is formed. On the other side portion thereof, the second
side plate 15 is formed. The second side plate 15 is formed of a
right-angled plate that is formed only of a flat-plate-like flat
surface portion. Note that, the lip 13 and the second side plate 15
have the same protruding length, and hence the transverse beam 2
apparently has a double-lip shape . However, the second side plate
15 may have a slightly larger length than that of the lip 13.
[0077] The second side plate 15 as the right-angled plate extends
in the right-angled direction orthogonal to the plate height
direction 12a of the back plate 12, and includes no lip 13.
Accordingly, the second side plate 15 is formed only of a flat
plate so as to prevent formation of puddles.
[0078] Note that, as illustrated also in FIG. 18, in a case where
the force indicated by the arrow C is applied to the transverse
beam 2 and thus the load test is performed, the entire transverse
beam 2 bends to a medium extent as indicated by a dotted line and a
solid line. Therefore, the transverse beam 2 has a sufficient load
capacity.
[0079] In addition, the longitudinal direction "A" of the
longitudinal beam 3 is oblique in FIG. 15, and hence even the same
double-lip channel steel bar as that used in the conventional
configuration is applicable as the longitudinal beam 3. However,
the single-lip channel steel bar of FIG, 16 having the same
configuration as that of the transverse beam 2 can be used as the
longitudinal beam 3.
[0080] Note that, a side plate width W.sub.1 of the side plate 14
extending in a direction orthogonal to the longitudinal direction
"A" is smaller than a back plate width W.sub.2 of the back plate 12
extending in another direction orthogonal to the longitudinal
direction "A". In a case of another embodiment illustrated in FIG.
17 corresponding to FIG. 16, the second side plate 15 is formed of
a lip, and the plate width W.sub.1 of the side plate 14 and the
plate width W.sub.2 of the back plate 12, which respectively extend
in the directions orthogonal to the longitudinal direction "A", are
equal to each other. The lip 13, the second side plate 15, the
first side plate 14, and the back plate 12 form a single-lip angle
steel bar 40 as a single-lip channel steel bar, and provide the
same actions on drainage and the like as those of the
above-mentioned embodiment illustrated in FIG. 16.
[0081] Further, a first protruding length WA of the second side
plate 15 protruding from the back plate 12, or a first protruding
length WA of the second side plate 15a protruding from the back
plate 12 is equal to a second protruding length WB of the lip 13
protruding from the first side plate 14.
[0082] Next, in a case of still another embodiment of the present
invention illustrated in FIGS. 19 and 20, each longitudinal beam 3
provided on the base members 4 is disposed in a horizontal state,
and the plurality of transverse beams 2 are provided on the
longitudinal beam 3 so as to be orthogonal to the longitudinal beam
3. The solar panel module 1 illustrated in FIG. 6 is placed and
provided on the transverse beams 2.
[0083] Therefore, all of the longitudinal beams 3, the transverse
beams 2, and the solar panel module 1 provided on the base members
4 are disposed in a horizontal state, and the other structural
components are the same as those of the configuration illustrated
in FIGS. 15 to 18. Accordingly, herein, the same components are
denoted by the same reference symbols, and description thereof is
omitted.
[0084] Next, in a case of still another embodiment of the present
invention illustrated in FIGS. 23 to 25, the transverse beam 2 and
the longitudinal beam 3 each have a configuration different from
the configurations illustrated in FIGS. 15 to 20.
[0085] That is, as illustrated in FIGS. 23 to 25, the transverse
beam 2 is formed of a single-lip channel steel bar corresponding to
the single-lip channel steel bars 2, 3 in the other embodiments
illustrated in FIGS. 16 and 17. As illustrated in FIGS. 21 and 22,
the back plate 12, the side plate 14, and the lip 13 are the same
as those of the configurations illustrated in FIGS. 16 and 17, but
the second side plate 15 is formed of the non-right-angled plate
15a. The non-right-angled plate 15a extends in the non-right-angled
direction inclined at 90 degrees or more with respect to the plate
height direction 12a of the back plate 12, and is formed only of
the flat surface portion that is inclined downward.
[0086] Therefore, on each longitudinal beam 3 provided in a
horizontal posture on the base members 4 and having a longitudinal
shape, the transverse beams 2 are disposed in a horizontal posture.
On the transverse beams 2, the plate-like solar panel module 1 is
placed and disposed in a horizontal state.
[0087] The longitudinal beam 3 has the same structure as that of
the transverse beam 2. In a case where the longitudinal beam 3 is
placed on the base members 4, the inclined member 20 having a wedge
shape is interposed between the non-right-angled plate 15a as the
second side plate 15 and each of the base members 4, and the
inclined member 20 is interposed also between the longitudinal beam
3 and the non-right-angled plate 15a of each of the transverse
beams 2. In this mariner, the solar panel module 1, the transverse
beams 2, and the longitudinal beams 3 can be disposed in a
horizontal state on the base members 4.
[0088] The non-right-angled plate 15a of each of the beams 2, 3
extends to be inclined downward. Accordingly, for example, unlike
the conventional configuration illustrated in FIG. 31, water is not
collected on the non-right-angled plate 15a and is completely
drained away. As a result, durability of each of the beams 2, 3 is
significantly enhanced.
[0089] Next, FIGS. 26 and 27 illustrate an assembly configuration
of each of the beams 2, 3 in a case where each of the beams 2, 3
illustrated in FIGS. 10 to 12 includes the non-right-angled plate
as the second side plate 15a.
[0090] That is, as illustrated in FIG. 26, the inclined member 20
is fitted onto the anchor bolt 21 of the base member 4, and the
longitudinal beam 3 is placed and fitted onto the anchor bolt
21.
[0091] Further, as illustrated in FIG. 27, the inclined member 20
is fitted onto the bolt 22 of the longitudinal beam 3 provided on
the base member 4, and the transverse beam 2 is laid on the
inclined member 20 and fitted onto the anchor bolt 22 through the
hole 2a of the transverse beam 2.
[0092] Therefore, according to the above-mentioned configuration,
the longitudinal beam 3 and the transverse beam 2 are arranged to
be orthogonal to each other and arranged to be stacked
vertically.
[0093] FIGS. 28 and 29 illustrate the configuration after
completion of assembly of the beams 2, 3 illustrated in FIG. 27.
FIG. 28 illustrates a lateral view of the transverse beam 2 that is
fastened with the nut 25. FIG. 29 illustrates a longitudinal view
of the transverse beam 2.
[0094] Note that, the inclined washer 30 and the nut 31 are used to
fix the longitudinal beam 3 as illustrated in FIG. 28, and the
inclined washer 30 is used to fix the transverse beam 2 as
illustrated in FIG. 29.

invention are applicable not only to a support block for an object,
but also to a bar frame, a scaffold, and the like for a house and
the like.
