Description

[Technical Field]

[0001] The present invention relates to a support device and a support structure for fixing and supporting a gable wrap to the "gable end" of a roof that is covered with folded-plate roofing materials. [Background technology]

[0002] In gable roofs that are covered with folded-plate roofing materials, it is essential to attach a gable cover to the end of the gable side from the perspective of weatherproofing, and examples of supporting structures for this are known, such as those disclosed in Patent Document 1 and Patent Document 2.

[0003] The support structures disclosed in the above Patent Documents 1 and 2 are both configured by attaching a support to an end tight frame that supports the corrugated roof material at the gable end, using this support to support the gable envelope, and engaging the joint ends (upper seam, lower seam, etc.) formed on the top wall of the corrugated roof material with the support to prevent the corrugated roof material from slipping out.

[0004] However, in the support structure of conventional gable wraps, when an excessive load is applied locally, such as when the weight of a worker is placed on the folded-plate roof material during roof-raising work, or when excessive negative pressure acts on the folded-plate roof, the fitting end of the folded-plate roof material is pulled in a direction away from the end tight frame, and the joint end comes into strong contact with the anti-slip portion of the support fixture, causing deformation. As a result, there is concern that the folded-plate roof material may shift from its designated position, and there is still room for improvement. [Prior art documents] [Patent documents]

[0005] [Patent Document 1] Japanese Patent Application Laid-Open No. 2006-45874 [Patent Document 2] Japanese Patent Application Publication No. 8-42075 DISCLOSURE OF THE INVENTION [Problem to be solved by the invention]

[0006] The object of the present invention is to propose a support device and a support structure that can stably support a gable wrap while maintaining a securely engaged state of a folded-plate roof material. [Means for solving the problem]

[0007] The present invention is a support device for fixing and supporting a gable wrap that covers and conceals the gable end of a roof covered with corrugated roofing material to the gable end, characterized in that it is connected to an end tight frame that supports the corrugated roof material at the gable end, and has a pressure plate that clamps the corrugated roof material between the head of the end tight frame and supports the gable wrap, and a locking plate that can be connected via a fastening means to an inner plate that is held hanging from the edge of the top plate of the gable wrap.

[0008] In the above support, the pressing plate has a connecting wall that can be connected to the leg of the end tight frame, an upright wall that rises from one end of the connecting wall, a top wall that is connected to the upper end of the upright wall and supports the top plate of the gable cover on its upper surface, a hanging wall that is suspended from the edge of the top wall and forms a storage space for the upper or lower seam provided on the top wall of the corrugated plate roof material located above in cooperation with the upright wall and the top wall, and a ground wall that is connected to the lower end of the hanging wall and is grounded along the head of the end tight frame, and the pressing plate is connected to the ground wall and fits into the constricted portion formed at the top of the inclined side wall of the corrugated plate roof material. It is preferable as a specific means for solving the problem that the corrugated roof material has a bent convex portion that applies a pulling force toward the head of the end tight frame, and that the pressure plate has a through hole for passing a fastener, and that the roof is a double roof with two roofs on the top and bottom, and the end tight frame is a lower end tight frame that supports the lower folded plate roof material of the double roof with two roofs on the top and bottom, and the pressure plate is connected to the head of the lower end tight frame via a base and clamps the upper folded plate roof material between the pressure plate and the base.

[0009] The present invention also provides a support structure for a gable wrap that supports the gable wrap on the gable end of a roof using a support device having the above-mentioned configuration, characterized in that the inner panel of the gable wrap is connected to the locking plate via a fastening means, and the lower end of the outer panel of the gable wrap is connected to the exterior wall via a fastening means. [Effects of the Invention]

[0010] According to the present invention, the folded-plate roofing material is sandwiched between the end tight frame and the retainer plate, so the folded-plate roofing material does not easily shift position. Also, according to the present invention, when the folded-plate roofing material is sandwiched between the end tight frame and the retainer plate, the bent convex portion applies a pulling force to the folded-plate roofing material toward the head of the end tight frame, and the folded-plate roofing material is firmly fastened to the end tight frame.

[0011] Furthermore, according to the present invention, the gable wrap is fixed to the locking plate through its inner panel, which provides high watertightness, and since the corrugated roof material and the gable wrap are not fastened together, even if there is a difference in thermal expansion and contraction between the corrugated roof material and the gable wrap, problems such as the head of the screw falling off due to the breakage of the fixing screw, or noise caused by the release of accumulated strain can be effectively avoided.

[0013] The present invention will now be described in more detail with reference to the drawings. Fig. 1 is a cross-sectional view of a support structure in which a support fixture according to the present invention is attached to an end tight frame placed at the gable end of a roof covered with folded-plate roofing materials, and the support fixture supports a gable wrap. Fig. 2 is a perspective view of the exterior of the support fixture according to the present invention, and Fig. 3 is a view showing the support fixture in an exploded state.

[0014] Before explaining the support devices and support structures of the present invention, we will first explain the folded-plate roofing materials, gable wrappers, and tight frames (including end tight frames) that support the folded-plate roofing materials used in roofing.

[0015] 1 to 3, the reference numeral 1 denotes a folded-plate roofing material used for roof construction. As shown in Figures 4(a) and 4(b), the folded-plate roofing material 1 is held in an upward outward opening position and is composed of a pair of inclined side walls 1a, 1b with a constricted portion K formed at the top, a groove wall 1c connecting the lower ends of the inclined side walls 1a, 1b, and top walls 1f, 1g connected via the constricted portion K formed at the top of the inclined side walls 1a, 1b and with an upper seam 1d and a lower seam 1e.

[0016] As shown in FIG. 5, the folded plate roof material 1 having the above-described configuration has its upper seam 1d and lower seam 1e, which serve as joint ends, fitted to the lower seam 1e and upper seam 1d of another adjacent folded plate roof material 1, and these are seam-fastened to connect the folded plate roof materials to each other. The folded plate roof material is supported by the tight frame T. By repeating this process, a wave-shaped roof is constructed in which peaks and valleys are alternately arranged from one end of the gable side to the other end of the gable side, as shown in FIG.

[0017] The tight frame T can be a clasp-less type having a pair of legs T1 and a head T2 provided at the upper ends of the pair of legs T1, and the claw portion T21 formed on the head T2 is fitted to the narrowed portion K of the folded-plate roofing material 1 to hold the folded-plate roofing material 1 in place.

[0018] The folded-plate roofing material 1 is made of a galvanized steel sheet, an aluminum-zinc alloy plated sheet, a stainless steel sheet, an aluminum sheet, a copper sheet, or a painted or coated steel sheet of these, each having a thickness of about 0.6 to 1.0 mm, more preferably about 0.8 mm, and is formed by subjecting a single plate material to forming processing such as roll forming. The length, width, and cross-sectional shape can be changed as appropriate and are not limited to those shown in the figure.

[0019] 1 to 3, the reference numeral 2 denotes a gable cover. The gable cover 2 is composed of an outer panel 2a located outside the gable end of the roof, a top panel 2b connected to the upper end of the outer panel 2a and extending toward the folded-plate roofing material 1, an inner panel 2c connected to the edge of the top panel 2b and suspended therefrom, a spring plate 2d connected to the lower end of the inner panel 2c and whose tip can abut against the outer surface of the folded-plate roofing material 1, and a connecting plate 2e connected to the lower end of the outer panel 2a and connected to the upper part of the exterior wall (such as a corrugated material) W of the building structure. A waterproof seal material (such as EPDM) S is placed between the spring plate 2d of the gable cover 2 and the folded-plate roofing material 1, and a chemical panel door W1 is placed at the upper end of the exterior wall W.

[0020] For the gable wrap 2, a galvanized steel plate, an aluminum-zinc alloy plated plate, a stainless steel plate, an aluminum plate, a copper plate, or a painted or coated steel plate of these, each having a thickness of about 0.6 to 1.0 mm, more preferably about 0.8 mm, can be used. The length and cross-sectional shape of the gable wrap 2 can be changed appropriately depending on the connection with the exterior wall, and are not limited to those shown in the figure.

[0021] 1 to 3, reference numeral 3 denotes an end frame supporting the roofing material 1 at the gable end. The end frame 3 is installed on the base material at intervals of 1 meter or less along the eaves to ridge of the roof. It is composed of a pair of legs 3a, 3b, a head 3c integrally connected to the upper ends of the legs 3a, 3b, and a bottom wall piece 3d connecting the legs 3a, 3b at their lower ends. Of the legs 3a, 3b, the outer leg 3a is held vertically, while the inner leg 3b is held at an angle equal to the slope of the sloped sidewall 1a of the roofing material 1. A constriction 3e is provided at the boundary between the leg 3b and the head 3c, matching the constriction K formed at the top of the sloped sidewall 1a of the roofing material 1.

[0022] The inclined side walls 1a and the top wall 1g of the folded-plate roofing material 1, including its constricted portion K, are installed in close contact with the legs 3b, head 3c, and constricted portion 3e of the end tight frame 3.

[0023] 1 to 3, reference numeral 4 denotes a support according to the present invention. The support 4 is fabricated by bending a metal plate material, such as zinc-plated steel, aluminum-zinc alloy-plated steel, stainless steel, aluminum, copper, or a painted or coated steel sheet of these materials, approximately 0.8 to 3.2 mm thick, into the desired shape. The support 4 is comprised of a pressure plate 4a and a locking plate 4b. The pressure plate 4a is connected to the leg 3a of the end frame 3 via a hook-shaped connecting piece 5, clamping the folded-plate roofing material 1 between itself and the head 3c of the end frame 3 and supporting the top plate 2b of the gable casing 2 with its upper surface. The locking plate 4b is provided on the upper surface of the pressure plate 4a (at a position different from the upper surface supporting the top plate 2b of the gable casing 2) and is connected to the inner plate 2c suspended at the edge of the top plate 2b of the gable casing 2 via fastening means 6, such as a drill screw.

[0024] The retaining plate 4a comprises a connecting wall 4a1 connectable to the leg 3a of the end tight frame 3 via a connecting piece 5, a standing wall 4a2 rising from one end of the connecting wall 4a1, a top wall 4a3 connected to the upper end of the standing wall 4a2 and supporting the top plate 2b of the gable roof covering 2 on its upper surface, and an upper seam 1d or a lower seam 1e (in the illustrated example, the lower seam 1e) provided on the top wall 1f, 1g of the folded-plate roof material 1 in cooperation with the standing wall 4a2 and the top wall 4a3. The roof is constructed of a hanging wall 4a4 that forms a storage space M (shown by Z1e), and a grounding wall 4a5 that is connected to the lower end of the hanging wall 4a4 and is grounded along the head 3c of the end tight frame 3, and the grounding wall 4a5 is connected to the grounding wall 4a5 and has a curved convex portion 4a6 that fits into the constricted portion K formed at the top of the inclined side wall 1a of the folded plate roof material 1, and a tongue piece 4a7 that is connected to the curved convex portion 4a6 and abuts against the inclined side wall 1a of the folded plate roof material 1.

[0025] The ground wall 4a5 can be provided with a bolt 4a8 crimped at that location, and the retaining plate 4a and the retaining plate 4b can be connected by inserting the bolt 4a8 into a through-hole formed in the retaining plate 4b and tightening a nut 4a9. The tongue 4a7 can be provided with a through-hole 4a10 as needed, and a fastener (such as a drill screw) 4a11 can be passed through the through-hole 4a10.

[0026] The retaining plate 4b can be composed of a vertical wall 4b1 that fits with the hanging wall 4a4 of the pressure plate 4a, a horizontal wall 4b2 that connects to the lower end of the vertical wall 4b1 and fits with the ground wall 4a5 of the pressure plate 4a, and an upright wall 4b3 with a lip that connects to the end of the horizontal wall 4b2.

[0027] The support device 4 according to the present invention firmly clamps the folded plate roof material 1 between the end tight frame 3 and the clamp plate 4a, with the bent convex portion 4a6 fitting into the constricted portion K of the folded plate roof material 1. At this time, the folded plate roof material 1 is subjected to a force that pulls the folded plate roof material 1 toward the head 3c of the end tight frame 3 by the bent convex portion 4a6. Therefore, even if an unexpected pulling force is applied to the folded plate roof material 1, the folded plate roof material 1 will be stably engaged and held in the end tight frame 3, and the folded plate roof material 1 will not easily shift position.

[0028] Furthermore, the support device 4 according to the present invention has high water-tightness because it can fix the gable wrap 2 to the locking plate 4b through its inner plate 2c, and furthermore, because the folded plate roof material 1 and the gable wrap 2 are not fastened together, even if there is a difference in thermal expansion and contraction between the long folded plate roof material 1 and the short gable wrap 2, there is an advantage that it is possible to effectively avoid the adverse effects that result from this, such as the head of the screw falling off due to the breakage of the fixing screw, or noise caused by the release of accumulated strain.

[0029] Furthermore, by providing a lipped upright wall 4b3 on the locking plate 4b, as shown in Figure 7, a through angle 7 with a grooved or L-shaped cross section can be temporarily fixed using a flat screw H, making it possible to fix the gable wrap 2 at multiple points from the eaves to the ridge of the roof without increasing the number of end tight frames 3 and supports 4 installed, and the gable wrap 2 can be supported even more firmly as a strong wind specification.

[0030] In addition, when using a retaining clip-less type tight frame such as the Tight Frame T or the End Tight Frame 3, it cannot be said that the folded plate roofing material 1 will not slide toward the eaves due to the influence of snow loads, etc. For this reason, when using a retaining clip-less type tight frame, the support 4 according to the present invention is intended for at least one support 4 located on the ridge side of the roof, and the support 4 is preferably fixed to the end tight frame 3 together with the folded plate roofing material 1 by passing a fastener 4a11 such as a drill screw through the through hole 4a10 formed in the tongue 4a7 of the retaining plate 4a. In this way, the gable wrap 2 can be supported by the support 4 without inhibiting the thermal expansion and contraction of the gable wrap 2 or the folded plate roofing material 1 in the eaves to ridge direction.

[0031] FIG. 8 is a diagram showing another embodiment in which a support 4 according to the present invention is applied to a double roof having an insulated structure, in which the roof is made up of folded-plate roofing materials 1 on top and bottom, and insulating material Z is laid between the layers as needed.

[0032] When applying the support 4 according to the present invention to a double roof, the end tight frame 3 is made into a lower end tight frame 8 consisting of legs 8a, 8b, a head 8c, and a bottom wall piece 8d, and supporting the lower folded plate roofing material 1 of the double roof that is laid on the top and bottom. Then, the holding plate 4a is connected to the lower end frame 8 via the base 9, and the upper folded plate roofing material 1 is sandwiched between the holding plate 4a and the base 9, and the gable wrapper 2 is supported on its upper surface. With the support 4 according to the present invention, the gable wrapper 2 can be reliably supported even at the gable end of the double roof.

[0033] The base 9 used for the double roof can be composed of a leg 9a with a grounding piece connected via a connecting piece 10 to the leg 8a of the lower end tight frame 8 located on the outside and held in a vertical position, a leg 9b with a grounding piece connected to the leg 8b of the lower end tight frame 8 located on the inside via a fastening means penetrating the lower folded plate roofing material 1, and a head 9c integrally connected to the upper ends of the legs 9a and 9b. In this case, the leg 9b is given a slope equivalent to the sloped sidewall 1a of the upper folded plate roofing material 1, and a constricted portion 9d is provided at the boundary between the leg 9b and the head 9c to fit the constricted portion K formed at the top of the sloped sidewall 1a of the upper folded plate roofing material 1. [Industrial Applicability]

[0034] According to the present invention, it is possible to provide a support device and a support structure that can stably support a gable wrap while maintaining a state in which the folded-plate roof material is securely engaged with the end tight frame. [Explanation of symbols]
