Description
CROSS-REFERENCE
[0001] This application claims priority from pending provisional
patent application Ser. No. 61/687,711 filed Apr. 30, 2012.
BACKGROUND
[0002] 1. Field of the Invention
[0003] A roof mounting system and method for mounting an array of
discrete modules to a roof.
[0004] 2. Description of the Prior Art
[0005] Existing attachment systems for mounting solar and other
equipment to the exteriors of building envelopes commonly follow
one of two general approaches.
[0006] The first attachment system includes penetration of the
envelope by mechanical attachment devices.
[0007] The second system consists of ballasting equipment in place
by loads of magnitudes greater than the predicted wind uplift and
overturning forces.
[0008] Each approach has significant drawbacks. For example,
mechanical anchors compromise the integrity of the building
envelope and increase the likelihood of leaks and magnify wind
forces by concentrating them all at a limited number of attachment
points.
[0009] On the other hand, ballasting can require loads greater than
the building envelope or roof can support. Most commercial roofs
are designed for a live load of 40 pounds per square foot, whereas
wind uplift in Florida and other high wind areas can exceed 80 per
square foot.
[0010] While some of the prior art may contain some similarities
relating to the present invention, none of them teach, suggest or
include all of the advantages and unique features of the invention
disclosed hereafter.
[0011] The present invention overcomes these problems by keeping
the wind as a distributed force over the entire footprint on the
building envelope of the equipment being installed or a lesser
attachment area as needed based upon site specific wind
engineering.
SUMMARY OF THE INVENTION
[0012] The present invention relates to a roof mounting system and
method for mounting an array of discrete modules to a roof.
[0013] The roof mounting system employs structural roofing
insulation or water proofing adhesive such as spray polyurethane
foam or other chemical agent to secure the roof mounting system in
place. This transfers the load forces directly to large areas of
the surface covering of the building envelope. Securing the roof
mounting system in this manner does not alter the wind forces at a
given location other than decoupling the internal portion (18%) of
the total wind force from the external portion of the total wind
force (82%). The building envelope resists internal pressure.
[0014] Furthermore, the roof mounting system resists the external
wind force and transfers the force through the adhesion to the
envelope of the building structural framing. The only change in
forces experienced by the building framing is the relatively small
additional gravity load of the roof mounting system adhered to the
envelope.
[0015] The roof mounting system is particularly useful in securing
a solar panel array to a roof by spray polyurethane foam that
creates a minimal gravity load of about 6 pounds per square foot
for typical installation well within the acceptable live load on
any current code compliant building.
[0016] The invention accordingly comprises the features of
construction, combination of elements, and arrangement of parts
which will be exemplified in the construction hereinafter set
forth, and the scope of the invention will be indicated in the
claims.
BRIEF DESCRIPTION OF THE DRAWINGS
[0017] For a fuller understanding of the nature and object of the
invention, reference should be had to the following detailed
description taken in connection with the accompanying drawings in
which: Similar reference characters refer to similar parts
throughout the several views of the drawings.
[0018] FIG. 1 is a perspective view of the roof mounting system of
the present invention.
[0019] FIG. 2 is a view of a stanchion of the present
invention.
[0020] FIG. 3 is a detailed disassembled view of the stanchion of
the present invention.
[0021] FIG. 4 is a partial view of an array of photovoltaic modules
mounted to a roof on support rails secured to the roof by a
plurality of stanchions.
DETAILED DESCRIPTION OF THE INVENTION
[0022] As shown in FIGS. 1 and 4, the present invention relates to
a roof mounting system and method for mounting an array of discrete
modules to a roof.
[0023] Specifically, a plurality of support rails each indicated as
1 is arranged on a roof 3 to cooperatively form a grid to support a
plurality of discrete modules such as a photovoltaic panels 5.
[0024] The plurality of support rails 1 may be secured or adhered
directly to the roof 3 by a spray polyurethane foam 2 upon the
spray polyurethane 2 may be combined with or covered by a
protective coating of elastomeric material.
[0025] Alternately, the support rails 1 may be mounted on a
plurality of stanchions each generally indicated as 6. Each
stanchion 6 comprises a base plate 7 coupled to an upright member 8
by a coupling element 9. Each stanchion 6 further includes a
fastening member 10 including a centrally disposed aperture or hole
11 to receive a fastener 12 thereto to secure the rails 1 to a
corresponding upright member 8 of the corresponding stanchion 6 by
a corresponding rail clamp 13.
[0026] The base plate 7 of each stanchion 6 is embedded or adhered
to the roof 3 by the spray polyurethane foam 2.
[0027] Spray polyurethane foam roofing systems exhibit excellent
adhesion properties to a variety of substrates including metal,
wood, concrete and built up roofing. However, the spray
polyurethane foam must be protected by elastomeric coatings or
other coverings to prevent UV-induced surface degradation.
[0028] Benefits of using spray polyurethane foam as an adhesive
include; rigid, lightweight, flexible, wind resistant, effective in
extreme weather and temperature conditions and high insulating
values.
[0029] It will thus be seen that the objects set forth above, among
those made apparent from the preceding description are efficiently
attained and since certain changes may be made in the above
construction without departing from the scope of the invention, it
is intended that all matter contained in the above description or
shown in the accompanying drawing shall be interpreted as
illustrative and not in a limiting sense.
[0030] It is also to be understood that the following claims are
intended to cover all of the generic and specific features of the
invention herein described, and all statements of the scope of the
invention which, as a matter of language, might be said to fall
therebetween.
[0031] Now that the invention has been described,
