Description

[Technical field]

[0001] The present invention relates to a support for a folded-plate roofing material that is installed and fixed on an underlay folded-plate roof and is suitable for laying an overlay folded-plate roof. [Background technology]

[0002] A folded-plate roof is made by forming a coil of steel sheet into a roofing material with a shape and length that corresponds to the shape and length of the roof using a roll forming machine installed at the construction site.The formed roofing material is then appropriately fixed to a tight frame placed on the base material of the building structure, and the roof is installed by fastening the upper and lower seams.The appearance of a folded-plate roof has a corrugated shape with alternating peaks and valleys.

[0003] Such a folded-plate roof can economically ensure ease of construction, wind pressure resistance, and water-stopping properties, and it is also possible to construct a double-layer folded-plate roof with high insulating properties by inserting insulation material between the underlayment folded-plate roof and the toplayment folded-plate roof, and it has become widely used for large-area roofs such as those in factories, warehouses, and large stores.

[0004] Prior art for laying an overlay folded-plate roof on an underlay folded-plate roof involves connecting the upper and lower connecting fittings with insulating fittings, arranging and fixing the lower connecting fittings to the top of the underlayment material, while placing the overlay folded-plate roof material on top of the upper connecting fittings and fastening them to the top surfaces of the peaks of the adjacent folded-plate roof materials, thereby laying the overlay folded-plate roof. For example, a support device such as that described in Patent Document 1 is known.

[0005] However, the above-mentioned conventional support is fixed to the underlayment folded plate roof by tightening the tightening bolt, and the degree of tightening varies depending on the worker, and if the degree of tightening is too large, the connecting part of the tight frame and the folded plate roof material may be excessively deformed, or the support itself may be deformed. Conversely, if the degree of tightening is small, there is a concern that the fixation of the support may become unstable, and there is still room for improvement.

This is a support device for folded plate roofing material.

[0009] In the support having the above configuration, one of the pair of legs has a notch portion formed with an open end at the lower end edge of the leg, the pair of legs each have a flange that rises at the widthwise end edge and extends continuously from the upper end to the lower end edge, the head is horizontal and flat, and has a top wall on which the folded plate roof material is grounded when supporting the folded plate roof material to prevent it from slipping out, the top wall is formed leaving the edge area of ​​the top wall, and has a partition recess that can connect the bottom wall and the connecting piece via a fastening means, and further, the partition recess has one or more openings in at least one of the bottom wall and the peripheral wall connecting the bottom wall and the top wall. In addition, the present invention can provide a widening piece that widens the leg body in the width direction at the end of the pair of legs. Effect of the Invention

[0010] According to the present invention, a rib is provided on the connecting piece, and when the fastening means is tightened, the end faces of the rib are abutted against each inner wall surface of the leg, preventing further tightening. Therefore, the support can be fixed and held on the underlayment corrugated roof with a constant degree of tightening.

[0011] In addition, according to the present invention, by providing a notch at the lower edge of the leg and making it possible to recognize that the tightening portion of the fastening means is on the side where this notch is present or on the opposite side, fastening work can be performed quickly, making it possible to efficiently install the corrugated roof.

[0013] The present invention will now be described in more detail with reference to the drawings. FIG. 1 is a schematic perspective view of a single piece of folded-plate roofing material used to lay a folded-plate roof, and FIG. 2 is a diagram showing two peaks of a folded-plate roof laid using the folded-plate roofing material shown in FIG.

[0014] The folded plate roofing material used for the folded plate roof is made of anti-rust treated steel plate such as hot-dip galvanized steel plate or color steel plate, or stainless steel plate, aluminum alloy plate, or zinc plate, which has a thickness of about 0.6 mm to 1.0 mm, and is formed by roll forming or press forming.

[0015] In Figures 1 and 2, the symbol 1a denotes a stepped groove plate shown in a rectangular shape, 1b and 1c denote stepped inclined side walls that are integrally connected over the entire length of the widthwise end of the groove plate 1a and rise at an angle outward in the widthwise direction, 1d and 1e denote peaks that are integrally connected to the upper ends of the inclined side walls 1b and 1c, and 1f and 1g denote upper and lower seams provided on the peaks 1d and 1e.

[0016] In this folded-plate roofing material, the upper seam 1f and the lower seam 1g are connected to the lower seam 1g' and the upper seam 1f' of another adjacent folded-plate roofing material. The jaws 1h, 1i, 1h', 1i' formed at the boundary between the peak top surface 1d, 1e, 1d', 1e' and the inclined side walls 1b, 1c, 1b', 1c' are hooked to the protruding parts 2a1, 2a2 formed on the head 2a of the tight frame 2, and the seam is rolled up while maintaining that state, thereby fixing and holding it to the tight frame 2. As a result, a folded-plate roof having a wave shape in which the grooves (concave parts) M and the peaks (convex parts) Y are alternately repeated along the eaves of the roof is laid.

[0017] Usually, to construct a double folded-plate roof using this type of folded-plate roofing material, a support as shown in Fig. 3 is used, in which the upper connection fitting 3 and the lower connection fitting 4 are connected with a heat-insulating fitting 5 (see Fig. 4). Then, as shown in Fig. 4(a), the support is installed on the underlay folded-plate roof 6, and the lower connection fitting 4 is fixed to the peak top surface 6a of the underlay folded-plate roof 6 by tightening the nut 7a of the fastening bolt 7, which is the fastening means. Furthermore, the overlay folded-plate roofing material 8, 8' is placed on the upper connection fitting 3, the jaws 8a1, 8a1' are hooked to the upper connection fitting 3, and the upper seam 8b and the lower seam 8c' provided on the peak top surface 8a, 8a' are seam-tightened to cover the overlay folded-plate roof.

[0018] However, in the support shown in Fig. 3, the degree of tightening of the nut 7a of the fastening bolt 7 varies depending on the worker, and if the degree of tightening of the nut 7a is too large, the connecting part of the tight frame 2 and the folded roof material may be excessively deformed, or the support itself may be deformed as shown in Fig. 4(b). Conversely, as mentioned above, there was a concern that if the degree of tightening of the nut 7a is not large enough, the fixation of the support may become unstable.

[0019] The present invention aims to construct a double folded-plate roof by laying an overlay folded-plate roof on an underlay folded-plate roof without causing such problems.

[0020] FIG. 5 is an external perspective view showing an embodiment of the support according to the present invention, and FIG. 6 is an external perspective view showing the support shown in FIG. 5 in an exploded state. FIG. 7 is a front view of the support shown in FIG. 5, and FIG. 8 is a view showing the support shown in FIG. 7 with the head removed. FIG. 9 is a plan view of the support shown in FIG. 7, FIG. 10 is a bottom view of the support shown in FIG. 7, FIG. 11 is a view showing the left side of the support shown in FIG. 7, FIG. 12 is a view showing the right side of the support shown in FIG. 7, FIG. 13 is a view showing the AA cross section of FIG. 9, FIG. 14 is a view showing the BB cross section of FIG. 9, and FIG. 15 is a view showing the use state of the support according to the present invention in which a heat insulating material is arranged between the underlay folded plate roof and the overlay folded plate roof.

[0021] Reference numerals 9 and 10 in Fig. 5 to Fig. 15 denote a pair of legs arranged to sandwich the mountain top surface portion 6a of the underlay folded plate roof 6 from both sides. The legs 9 and 10 are composed of a leg body 9a, 10a formed by appropriately bending a metal plate-like member, and a flange 9b, 10b that stands at the edge in the width direction of the leg body 9a, 10a and extends continuously from the upper end to the lower end. The leg body 9a, 10a is provided with jaws 9c, 10c that are hooked via the underlay folded plate roof 6 to the overhanging portions 2a1, 2a2 provided on the head portion 2a of the tight frame 2 that supports the underlay folded plate roof 6 by fastening with a fastening means described later, and protruding portions 9d, 10d, for example, having a trapezoidal shape that bulges outward to increase the strength of the leg body 9a, 10a. The projections 9d and 10d may be bulging inward, and there is no limitation on their shapes.

[0022] 5 to 15, reference numeral 11 denotes a connecting piece that connects the upper ends of the pair of legs 9, 10. The connecting piece 11, like the legs 9, 10, is made of a metal plate-like member.

[0023] 5 to 15 denotes a fastening means that is disposed across the pair of legs 9, 10 and that, when fastened, hooks the jaws 9c, 10c of the legs 9, 10 onto the protruding parts 2a1, 2a2 of the head 2a of the tight frame 2. The fastening means 12 may be one that is made up of a connecting bolt 12a and a nut 12b that screws onto the connecting bolt 12a.

[0024] Also, the reference numeral 13 in Figs. 5 to 15 denotes a head portion that is fixed and held to the connecting piece 11 via an intermediate member S, and that links the overlay folded-plate roofing material 8, 8' to the jaw portion 8a1, 8a1' to hold the overlay folded-plate roofing material 8, 8' in place. The head portion 13 is made of a metal member, and has a trapezoidal front shape. On both the left and right ends of the head portion 13, there are provided overhanging portions 13a, 13b that can be linked to the jaw portion 8a1, 8a1' of the overlay folded-plate roofing material 8. The intermediate member S forms a heat insulating layer between the legs 9, 10 including the connecting piece 11 and the head portion 13, and is made of, for example, a material such as synthetic resin or rubber. The intermediate member S can also function as a spacer that adjusts the height of the head portion 13.

[0025] The head 13 is horizontal and flat, and has a top wall 13c on which the overlay folded-plate roofing materials 8, 8' contact when supporting the folded-plate roofing materials 8, 8' to prevent them from slipping out. The top wall 13c is preferably provided with a track-shaped, planar compartment recess 13d that is formed leaving its edge area and whose bottom can be connected to the connecting piece 11 via a fastening means 14.

[0026] When the fastening means 14 is composed of a connecting bolt 14a and a nut 14b screwed onto the connecting bolt 14a, the compartment recess 13d forms a space for accommodating the nut 14b or the head of the connecting bolt 14a. One or more openings 13e can be provided in at least one of the bottom wall of the compartment recess 13d and the peripheral wall connecting the bottom wall and the top wall 13c. By providing the openings 13e, even if moisture such as rainwater enters the compartment recess 13d of the head 13, it can be efficiently discharged from the openings 13e.

[0027] The fastening means 14 may connect the head 13 and the connecting piece 11 by using rivets, rivets, welding, etc. instead of the connecting bolts 14a and nuts 14b.

[0028] The connecting bolt 14a can also be reversed to position the head of the connecting bolt 14a within the compartment recess 13d, and then rotated to tighten the connecting bolt 14a into the nut 14b fixed to the underside of the connecting piece 11.

[0029] 5 to 15, reference numeral 15 denotes a rib suspended from each widthwise edge of the connecting piece 11. The rib 15 has an end face 15a directed toward each inner wall face of the legs 9, 10.

[0030] The rib 15 reinforces the connecting piece 11, and also functions as a stopper that regulates the distance between the legs 9, 10 when the nut 12b of the fastening means 12 is tightened, with the end face 15a coming into contact with the inner wall surfaces of the legs 9, 10. The rib 15 is made of the same material as the connecting piece 11 and the legs 9, 10.

[0031] Between the connection part of the width direction end of the rib 15 with the connecting piece 11 and the connection part of the upper end of the legs 9, 10 with the connecting piece 11, a bridge part 15b that connects the rib 15 and the legs 9, 10 to each other via the connecting piece 11 can be provided. The bridge part 15b elastically connects the legs 9, 10 to the connecting piece 11 (applies a spring-like biasing force (restoring force)). For example, when the fastening by the nut 12b of the fastening means 12 is released to remove the support from the peak top surface 6a of the underlay folded plate roof 6, the biasing force makes it possible to return the mutual distance between the legs 9, 10 to the original distance, making it easy to remove the support. Note that the bridge part 15b can be a convex part or the like that is bulged outward by bending.

[0032] 5 to 15 designate a notch provided in leg 10. It is preferable that notch 16 be provided in an area excluding the center in the width direction of leg 10, but it is also possible to provide it in the center in the width direction, or it is also possible to provide it in leg 9.

[0033] To fix the support according to the present invention onto the underlayment folded plate roof 6, the legs 9, 10 of the support are positioned on both sides of the peak portion 6a of the underlayment folded plate roof 6, and the nuts 12b of the fastening means 12 are tightened.

[0034] As the nut 12b of the fastening means 12 is tightened, the legs 9, 10 move closer to each other while undergoing elastic deformation, starting from the connection points of the connecting pieces 11, until the end faces 15a of the ribs 15 come into contact with the inner wall surfaces of the legs 9, 10.

[0035] The nuts 12b of the fastening means 12 cannot be tightened any further when the end faces 15a of the ribs 15 are in contact with the inner wall faces of the legs 9 and 10. Therefore, the tight frame 2 and the support will not be deformed due to excessive tightening, and conversely, the fixation of the support will not become unstable due to insufficient tightening.

[0036] The gap h (see Figure 8) formed between the end face 15a of the rib 15 and the inner wall surfaces of the legs 9, 10 is preferably set to about 1.0 to 5.0 mm, a value that allows the legs 9, 10 to securely clamp the tight frame 2 together with the peak top surface 6a without excessive deformation of the tight frame 2 or the underlaying folded plate roof 6.

[0037] Figures 16(a) and (b) show the essential parts of another embodiment of a support according to the present invention, in which a protrusion 17 is provided on the inner wall surface of the leg main bodies 9a and 10a so that the end face 15a of the rib 15 comes into surface contact with the inner wall surface of the leg main bodies 9a and 10a.

[0038] The provision of the protrusions 17 stabilizes the contact posture of the legs 9, 10 against the end faces 15a of the ribs 15. Although the protrusions 17 are shown provided on the leg bodies 9a, 10a, they can also be provided on the end faces 15a of the ribs 15, and the end faces of the ribs 15 can also be shaped to contact with each other on a surface.

[0039] The cutout 16 is provided on the leg 10 as an example, but in this case, the head of the connecting bolt 12a of the fastening means 12 is located on the side opposite to the side on which the cutout 16 is provided, so the nut 12b of the fastening means 12 is located on the opposite side to the side on which the cutout 16 is provided. Therefore, it is possible to know which side the nut 12b is located just by visually checking the cutout 16, and the overlay folded plate roof can be efficiently laid. In particular, the existence of the cutout 16 is very significant when the fastening means 12 cannot be visually observed during the complicated work of fixing the support while positioning the overlay folded plate roof material 8, 8' above the support, or when the fixing work needs to be performed while looking at the support from directly above.

[0040] In the support device according to the present invention, the leg bodies 9a, 10a, flanges 9b, 10b, connecting pieces 11, and ribs 15 that constitute the legs 9, 10 can be formed from a single metal plate-shaped member by press processing or the like, which has the advantage of requiring a small number of parts.

[0041] 17 and 18 show still another embodiment of the support device according to the present invention. The support shown in Figures 17 and 18 above is similar to the support shown in Figure 5 above in that it has a rib 15 whose end face 15a abuts the inner wall surface of the legs 9 and 10 to avoid excessive tightening by the nut 12b of the fastening means 12, but it has a configuration in which widening pieces 18 and 19 are integrally provided at the ends of the legs 9 and 10 to widen the leg bodies 9a and 10a, respectively, in the width direction.

[0042] The widening pieces 18, 19 increase the contact area with the roof and stabilize the fixing position of the support. The rib 15 may be exposed from the lower end of the head 13 as shown in Fig. 7, or may be sized to fit inside the head 13.

[0043] Needless to say, the support members shown in Figs. 17 and 18 may also be provided with the notches 16 as required. [Industrial Applicability]

[0044] According to the present invention, a support for a folded-plate roof material can be provided that can be fixed and held on an underlay folded-plate roof with a constant degree of tightening. [Explanation of symbols]
