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 double roof (hereinafter referred to as the "gable end"), which is covered on the top and bottom with folded-plate roofing materials. [Background technology]

[0002] In the case of a gable-type double roof that is covered with folded-plate roofing materials, it is essential to install a gable cover at the end of the gable side to protect it from rain, and a support structure for this is known, for example, as disclosed in Patent Document 1.

[0003] The support structure disclosed in the above Patent Document 1 is constructed in such a way that the fixing portion of one of the clamping members of the support member that fixes the end of the top roof panel and the end of the underlayment roof panel is fixed to the top surface of the roof support frame by a third fastening member via the mounting portion of the fastener, the upper outer surface of the inclined surface of the underlayment roof panel is abutted against the inclined portion of the other clamping member, and the folded portion is positioned above the step portion of the underlayment roof panel, and it was said that this could stabilize the assembled state of the support member.

[0004] However, conventional support structures for gable covers simply hook the peaks of the top roof shingles onto the hooking parts that are bent upward in a convex shape, and there is a concern that when an excessive load is applied locally, such as when the weight of a worker is placed on the top roof shingle during roof installation work, or when excessive negative pressure acts on the roof, the peaks of the top roof shingles will be pulled in a direction away from the hooking parts, and the shape of the peaks will be deformed, causing the top roof shingle to shift from its designated position.

[0005] In addition, this support structure attaches intermediate fittings to the peaks of the roof shingles in areas where there is no roof support frame, and the inside of the gable wrap is fixed via these intermediate fittings, which requires the preparation of separate members from the support members, and the work of fixing the gable wrap to the intermediate fittings must be done separately from the work of attaching the support members installed on the roof support frame, making it difficult to efficiently install the gable wrap. Moreover, the fixing strength of the gable wrap depends on the deformation strength of the peaks of the roof shingles, and if the peaks of the roof shingles are unexpectedly deformed, there is a risk that the fixing of the gable wrap will become unstable. [Prior art documents] [Patent documents]

[0006] [Patent Document 1] Japanese Patent Application Publication No. 8-333848 DISCLOSURE OF THE INVENTION [Problem to be solved by the invention]

[0007] The object of the present invention is to propose a support and a support structure that can reliably fasten a folded-plate roof material and stably support a gable wrap with high mounting strength. [Means for solving the problem]

[0008] The present invention is a support device for fixing and supporting a gable wrap that covers and conceals the gable end of a double roof, which is covered above and below with folded plate roofing materials, to the gable end, and is characterized by having a base that is placed between the lower and upper folded plate roofing materials of the double roof and connects its legs to the end tight frame that supports the lower folded plate roofing material, and the base has a presser plate attached to its top that clamps the upper folded plate roofing material between itself and the top of the base and supports the gable wrap, and a locking plate attached to the presser plate that can be connected via fastening means to an inner plate that is held hanging at the edge of the top plate of the gable wrap.

[0009] In the gable roof support having the above-mentioned configuration, the base has a cushioning member at its leg portion that is interposed between the end tight frame and the end tight frame to block heat that goes in and out through the end tight frame, and the holding plate has a connecting wall that can be connected to the leg portion of the base, a standing wall that rises from one end of the connecting wall, a top wall that is connected to the upper end of the standing wall and supports the top plate of the gable roof on its upper surface, and a top wall that is suspended from the edge of the top wall and cooperates with the standing wall and the top wall to support the top wall of the folded plate roof material located above. A specific means for solving the problem is preferably one that has a hanging wall that forms a storage space for the installed upper or lower seam, and a grounding wall that is connected to the lower end of the hanging wall and is grounded along the head of the base, and further, the pressure plate is connected to the grounding wall and has a bent convex portion that fits into a constricted portion formed at the top of the inclined side wall of the upper folded plate roof material and applies a pulling force to the upper folded plate roof material toward the head of the base, and further, the pressure plate has a through hole to pass a fastener through.

[0010] The present invention also provides a support structure for a gable wrap that supports the gable wrap on the gable end of a double 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]

[0011] According to the present invention, the gable wrap can be stably supported with high attachment strength while the folded plate roof material is securely fastened at the gable end.

[0012] In addition, according to the present invention, the cushioning member placed between the legs of the base and the end tight frame can block heat from entering or leaving through the end tight frame, thereby improving the insulating efficiency of the gable end of the double roof.

[0014] 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 device according to the present invention is attached to an end tight frame placed at the gable end of a double-layered roof on which thermal insulation is laid, and the support device supports a gable wrap. Fig. 2 is a perspective view of the exterior of the support device for the gable wrap according to the present invention, and Fig. 3 is a view showing the support device in an exploded state.

[0015] 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 to roof a double-layered roof.

[0016] 1 to 3, the reference numeral 1 denotes a folded-plate roofing material. As shown in Figures 4(a) and (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.

[0017] As shown in FIG. 5, the folded plate roof material 1 having the above-mentioned configuration has its upper seam 1d and lower seam 1e as joint ends adapted to the lower seam 1e and upper seam 1d of another adjacent folded plate roof material 1, and these seam fastened to connect the folded plate roof materials together. The lower folded plate roof material 1 is supported on the tight frame T, and once this support is complete, the upper folded plate roof material 1 is supported via the support bracket U. This work is repeated above and below, and by appropriately laying insulation material Z between the lower folded plate roof material 1 and the upper folded plate roof material 1, as shown in FIG. 6, a double roof (insulated double roof) with a corrugated shape in which peaks and valleys are alternately arranged from one gable end to the other gable end is laid.

[0018] The tight frame T that holds the lower-positioned corrugated roof material 1 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 corrugated roof material 1 to hold the corrugated roof material 1 in place.

[0019] In addition, the support bracket U that supports the upper folded plate roofing material 1 is a retaining clipless type that has a pair of legs U1 that fit into the narrowed portion K of the lower folded plate roofing material 1 to securely hold the support bracket U, and a head U2 provided at the upper end of the pair of legs U1, and by fitting the claw portion U21 formed on the head U2 into the narrowed portion K of the upper folded plate roofing material 1, the folded plate roofing material 1 is held in place by the support bracket U.

[0020] 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.

[0021] 1 to 3 designates a gable cover. The gable cover 2 is made up of an outer panel 2a located outside the gable end of the double-layered 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 capable of abutting 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.

[0022] 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.

[0023] 1 to 3, the reference numeral 3 denotes an end tight frame that supports the lower folded-plate roofing material 1 at the gable end. The end tight frame 3 is installed on the base material at intervals of 1 meter or less along the eaves to ridge of the double-layered roof, and is made up of a pair of legs 3a, 3b, a head 3c that is integrally connected to the upper ends of the pair of legs 3a, 3b, and a bottom wall piece 3d that connects the legs 3a, 3b to each other at their lower ends.

[0024] Of the pair of legs 3a, 3b, the outer leg 3a is held in a vertical position, and the inner leg 3b is held in an inclined position with an inclination equivalent to that of the inclined side wall 1b of the lower corrugated roof material 1, and at the boundary between the leg 3b and the head 3c, a constricted portion 3e is provided that fits into the constricted portion K formed at the top of the inclined side wall 1b of the corrugated roof material 1.

[0025] The inclined side wall 1b and top wall 1f of the lower folded plate roof material 1, including its constricted portion K, are installed in close contact with the leg portion 3b, head portion 3c, and constricted portion 3e of the end tight frame 3.

[0026] 1 to 3, reference numeral 4 denotes a support according to the present invention. The support 4 is manufactured by bending a metal plate material having a thickness of approximately 0.8 to 3.2 mm, such as a zinc-plated 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 thereof, into the desired shape. The support 4 is composed of a base 4a, a pressure plate 4b, and a locking plate 4c. The base 4a is disposed between the lower folded-plate roofing material 1 and the upper folded-plate roofing material 1, and the pressure plate 4b is attached to the top of the base 4a and clamps the upper folded-plate roofing material 1 between the base 4a and the top of the base 4a, while its upper surface supports the top plate 2b of the gable roof covering 2. In addition, the locking plate 4c is provided on the upper surface of the pressure plate 4b (an upper surface at a position different from the upper surface supporting the top plate 2b of the gable cover 2) and is connected to the inner plate 2c held hanging down at the edge of the top plate 2b of the gable cover 2 via fastening means 5 such as drill screws.

[0027] In the support 4, the base 4a can be configured with a leg 4a1 located on the outside and connected to the leg 3a of the end-mounted tight frame 3 held in a vertical position via a connecting piece 6, a leg 4a2 located on the inside and connected to the leg 3b of the end-mounted tight frame 3 via a fastening means penetrating the lower folded-plate roofing material 1, and a head 4a3 integrally connected to the upper ends of the legs 4a1 and 4a2. In this case, the leg 4a2 is given a slope equivalent to the sloped sidewall 1b of the upper folded-plate roofing material 1, and a constricted portion 4a4 is provided at the boundary between the leg 4a2 and the head 4a3 to fit the constricted portion K formed at the top of the sloped sidewall 1b of the upper folded-plate roofing material 1. Note that both legs 4a1 and 4a2 can be provided with grounding pieces 4a11 and 4a21 at their lower ends.

[0028] In the support 4, the pressing plate 4b comprises a connecting wall 4b1 connected to the leg 4a1 of the base 4a via a connecting piece 7, an upright wall 4b2 rising from one end of the connecting wall 4b1, a top wall 4b3 connected to the upper end of the upright wall 4b2 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 (see Fig. 1) provided on the top wall 1f, 1g of the folded-plate roof material 1 located above the upright wall 4b2 and the top wall 4b3. In the example shown, the roof is configured with a hanging wall 4b4 that forms a storage space M for storing a roofing member (shown as an upper seam 1d), and a ground wall 4b5 that is connected to the lower end of the hanging wall 4b4 and is grounded along the head 4a3 of the base 4a. The ground wall 4b5 is provided with a bent convex portion 4b6 that is connected to the ground wall 4b5 and fits into the constricted portion K formed at the upper part of 1b of the folded-plate roofing material 1, and a tongue piece 4b7 that is connected to the bent convex portion 4b6 and abuts against the inclined side wall 1b of the folded-plate roofing material 1. The ground wall 4b5 can be provided with a bolt 4b8 that is crimped at that position, and the bolt 4b8 can be inserted into a through hole formed in the locking plate 4c and tightened with a nut 4b9 to connect the holding plate 4b and the locking plate 4c. The tongue piece 4b7 can be provided with a through hole 4b10 as required, and a fastener 4b11 such as a drill screw can be passed through the through hole 4b10.

[0029] The retaining plate 4c in the support 4 can be composed of a vertical wall 4c1 that fits with the hanging wall 4b4 of the pressure plate 4b, a horizontal wall 4c2 that connects to the lower end of the vertical wall 4c1 and fits with the ground wall 4b5 of the pressure plate 4b, and an upright wall 4c3 with a lip that connects to the end of the horizontal wall 4c2.

[0030] 1 to 3, reference numeral 8 denotes a buffer member attached to the grounding pieces 4a11 and 4a21 of the legs 4a1 and 4a2 of the base 4a. The buffer member 8 is interposed between the end-mounted tight frames 3 to block heat entering and leaving through the end-mounted tight frames 3, thereby improving the thermal insulation performance of the gable end of the double-layered roof. The buffer member 8 is made of synthetic resin or rubber. Insertion grooves may be provided in the buffer member 8 into which the grounding pieces 4a11 and 4a21 of the legs 4a1 and 4a2 can be inserted. By using the insertion grooves to attach the buffer member 8 to the grounding pieces 4a11 and 4a21 of the legs 4a1 and 4a2 in advance, the base 4a can be efficiently attached to the end-mounted tight frames 3. The boundaries between the legs 4a1 and 4a11 and between the legs 4a2 and 4a21 each have notches to allow for insertion and installation of the buffer member 8.

[0031] The support device 4 according to the present invention firmly clamps the folded-plate roof material 1 between the base 4a and the clamp plate 4b, with the bent convex portion 4b6 of the clamp plate 4b fitting into the constricted portion K of the folded-plate roof material 1. At this time, the bent convex portion 4b6 acts on the folded-plate roof material 1 to pull it up toward the head 4a3 of the base 4a. 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 to the base 4a, and the folded-plate roof material 1 will not easily shift position.

[0032] In addition, the support device 4 according to the present invention can block heat entering and leaving through the end tight frame 3 using the buffer member 8, making it possible to improve the insulation at the gable end of the double roof, and the gable wrapping 2 has high water-tightness because it is fixed to the locking plate 4c through the inner plate 2c, and furthermore, since the folded plate roof material 1 and the gable wrapping 2 are not fastened together, there is an advantage that even if there is a difference in thermal expansion and contraction between the long folded plate roof material 1 and the short gable wrapping 2, the adverse effects caused by this, such as the head of the fixing screw falling off due to breakage, or noise caused by the release of accumulated strain, can be effectively avoided.

[0033] In particular, by providing a lipped upright wall 4c3 on the locking plate 4c, as shown in Figure 7, a through angle 9 with a grooved or L-shaped cross section can be temporarily fixed using a flat screw H, and the gable wrap 2 can be fixed 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, making it possible to support the gable wrap 2 even more firmly as a strong wind specification.

[0034] In addition, when using a clasp-less type tight frame such as the Tight Frame T or the End Tight Frame 3, it cannot be said that the upper folded plate roofing material 1 will not shift toward the eaves due to the influence of snow loads, etc. For this reason, when using a clasp-less type tight frame, the support 4 according to the present invention is targeted at at least one support 4 located on the ridge side of the double roof, and it is possible to fix the hold-down plate 4b to the base 4a together with the folded plate roofing material 1 by passing a fastener 4b11 such as a drill screw through the through hole 4b10 formed in the tongue 4b7 of the hold-down plate 4b. This allows the gable wrap 2 to 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.

[0035] 8 is a diagram showing an example of a support structure in which a gable cover 2 is supported at the end of the gable side using a base 4a, retaining clips 10, and a top plate fitting 11 fixed by the retaining clips 10. Even in this structure, it is possible to provide buffer members 8 on the grounding pieces 4a11, 4a21 of the legs 4a1, 4a2 of the base 4a, blocking heat entering and leaving through the end tight frame 3 and improving insulation efficiency. [Industrial Applicability]

[0036] The present invention provides a support device and support structure that can stably support the gable wrap with high attachment strength while maintaining a secure engagement of the folded-plate roof material at the gable end. Also, the present invention can improve the insulation efficiency of the gable end of the double-layered roof. [Explanation of symbols]
