[Industrial applications]

 The present invention relates to a thin metal rhombic roofing material that is used as a roof of a building.

[0002]

[Prior art]

 Conventionally, fired roof tiles and cement roof tiles have been used as roofing materials for buildings, but they have the drawbacks of being heavy and cracking, so in recent years they have been formed by bending thin metal plates. A roof material that is light and does not break is disclosed in, for example, Japanese Unexamined Patent Publication No. 4-62251, in which the upper side and the lower side of a diamond-shaped plate are bent to form a hook groove on the upper side and a height on the lower side. A roofing material with a side wall and a hooking piece that has been increased is proposed, and the work is performed while the lower hooking piece is fitted in the hooking groove on the upper side.

[0003]

[Problems to be solved by the device]

 However, in the roofing material described in the above publication, the sidewalls that are connected to both lower portions of the roofing material linearly increase in height to form the lower corners of the roofing material, and one roofing material A is not used for construction. Since it is constructed so as to cover the upper parts of the other roofing materials B and C arranged diagonally below, a relatively large gap is created between the lower roofing materials B and C and the upper roofing material A, When the wind and rain are strong, there is a problem that rainwater may enter through the gap due to rewinding. The present invention has been made in view of such circumstances, and an object of the present invention is to provide a rhombic roofing material which is strong in wind and rain and which is difficult for rainwater to enter even if it is rolled up.

[0004]

[Means for Solving the Problems]

 A rhombic roofing material according to claim 1, which is in accordance with the above object, has a retaining groove formed by folding back two sides on the upstream side of a diamond-shaped sheet material whose main part is a roof plate, and an upstream side of the retaining groove. The two sides folded back to the side are folded back to the front side, and a further extended roof base fixing portion is formed, and a side wall formed by bending the two sides at right angles to the back side on the downstream side of the plate material, and a tip portion of the side wall. Is a lozenge-shaped roofing material in which an engaging piece is formed by further bending the inner wall at a right angle and the height of the side wall is gradually increased toward the downstream side. A backup material made of plastic or rubber is attached to which the thickness gradually increases in the downstream direction according to the height of the side wall, and further, the downstream side intersections of the left and right side walls are further projected in the back surface direction. Front cover that closes the gap between adjacent diamond roof materials It is provided. The diamond roof material according to claim 2 is the diamond roof material according to claim 1, wherein an upstream end of the roof base fixing portion is folded back to the front surface side. Further, a rhombic roofing material according to a third aspect of the present invention is the rhombic roofing material according to the second aspect, wherein the plate material at the tip of the engaging piece is bent by 180 degrees. Here, the plate material includes, for example, a stainless plate, a corrosion-resistant coated iron plate, an aluminum plate, a clad steel plate, a titanium steel plate, a damping steel plate, and the like.

[Action]

 Next, the operation of the rhombic roofing material will be described, but for ease of understanding, different rhombic roofing materials will be described with different reference numerals A to D, respectively. The rhomboid roofing material according to claims 1 to 3 is formed by folding back two upstream sides of the rhomboidal plate material to the front surface side to form a retaining groove, and further extending the folding piece to form a roof base fixing portion. Therefore, by fixing this roof base fixing part to the roof base with nails or screws, each rhomboid roofing material is fixed to the roof base from the downstream side, and the entire roof except the bottom is constructed. it can. In this case, after one rhombic roofing material D is attached to the roof substrate, another rhomboidal roofing materials B and C arranged diagonally above both are formed by bending the downstream two sides at right angles to the back surface side. The thus-obtained hooking piece is inserted into the hooking groove in the upper portion of the diamond-shaped roofing material D and attached. Then, the other engaging pieces of the rhombic roofing material A are fitted in the adjacent retaining grooves of the two rhombic roofing materials B and C, respectively, and the rhombic roofing material A on the upstream side of the rhombic roofing material D is attached. In this case, the lower end of the rhombic roofing material A is provided with a front cover part that closes the gap between the adjacent rhombic roofing materials B and C so as to project downward. It is possible to prevent the infiltration of rainwater that is blown in by the wind. Then, since a backup material made of plastic or rubber is fixed along the thickness at the center of the rear surface side of each rhombic roof material, it is possible for an operator to stand on this rhombic roof material, Furthermore, heat insulation and soundproofing can be improved. Particularly, in the diamond roof material according to claim 2, since the upstream end portion of the roof base fixing portion is folded back to the surface side, it is possible to prevent the entry of rainwater blown by wind or the like, and further, the plate material. Since the cut end of is not exposed to the outside, it is less likely to cause injury during handling. In the diamond roof material according to the third aspect, since the tip end portion of the engaging piece is bent by 180 degrees, the portion is reinforced so that deformation is less likely to occur. Therefore, the straight line can be held, and insertion into the retaining groove is facilitated during construction. In addition, when this part is hooked on the hand and conveyed, injury or the like is unlikely to occur.

FIG. 4 is a perspective view when the diamond roof material is constructed, FIG. 5 is a sectional view taken along the line CC in FIG. 4, FIG. 6 is a partial front view of a diamond roof material according to another embodiment, and FIG. It is a partial bottom view.

As shown in FIG. 1 to FIG. 3, the plate material used for the rhomboid roofing material 10 according to one embodiment of the present invention has a thickness of about 0.3 to 1 mm, and has corrosion resistance treatment (eg, zinc plating) and corrosion resistance. Painted steel sheets or stainless steel sheets are used. A rhombic roofing material 10 according to one embodiment of the present invention is formed by folding back two sides of the substantially rhombic plate material on the upper side (that is, the upstream side) to the surface side, and further forming hooking grooves 11 and 12. At a portion of about 1 cm, it is folded back to the front side and extended by about 4 cm to form roof base fixing portions 13 and 14.

Then, the lower side (that is, the downstream side) of the plate member is bent at a right angle to the back surface side to form side walls 15 and 16, and the tip portion thereof is bent at a right angle to the inside, and the engaging piece 17 is formed. , 18 are formed. In this case, the bending positions are determined so that the heights of the side walls 15 and 16 are gradually increased in a straight line downward in a symmetrical manner. Thereby, as shown in FIG. 2, the inclination angle α of the central portion of the rhombic roofing material 10 becomes about 2 to 3 degrees. As shown in FIG. 3, the rhombic roofing material 10 according to this embodiment has a slight downward slope (β = 0.5 to 1 degree) in the left and right directions to increase the strength of the plate. The flow of rainwater is also made to flow slightly to the left and right.

A contour of the periphery of the roof plate 19 is formed by the bent portions of the retaining grooves 11 and 12 and the side walls 15 and 16. The crossover portions above the roof base fixing portions 13 and 14 are notches. A front cover portion 20 is provided at the lower intersection of the side walls 15 and 16. The front cover portion 20 has an arc shape in plan view, and upper portions on both sides thereof are connected to the side walls 15 and 16, and the height thereof is higher than the lower ends of the side walls 15 and 16 and protrudes downward. This protruding height is approximately the same as or slightly higher than the height on both sides of the rhombus roofing material 10, and its width H is, as shown in FIG. 4, when the rhombus roofing materials 10 are arranged side by side. It has a length that covers the connecting portion of the material.

A backup material 21 is attached to the back surface of the roof plate 19. The back-up material 21 is made of foamed plastic (for example, foamed polyethylene) or rubber, and is provided with an adhesive or the like at the center of the roof plate 19, more specifically, at a position that does not hinder the connection between the diamond-shaped roofing materials 10. It is joined. Further, the backup material 21 corresponds to the height of the side walls 15 and 16, and is gradually thickened linearly toward the downstream side. As a result, when a person is placed on the rhombic roofing material 10, it is prevented from being deformed, and the heat insulating effect and the soundproofing effect are exhibited.

Further, as shown in FIGS. 1 and 5, the tip end portions of the roof base fixing portions 13 and 14 are bent to the front side by 150 degrees (preferably about 120 to 180 degrees) to reinforce the ends. In addition, it is designed to prevent the entry of rainwater that is blown by the wind, etc., and the cut edge of the plate will not come out and cause injury. The tips of the engaging pieces 17 and 18 are bent to the back side by 180 degrees to reinforce the ends, and when the portions are hooked in the hand, the ends of the plates will not cause injury.

Therefore, in the construction of a roof using the rhombic roofing material 10, as shown in FIG. 4, the roofing material 22 that uses the upper half of the rhombic roofing material 10 and has a side wall at its downstream end is used. After being fixed on the roof base 23, the diamond-shaped roofing material 10 (D) is attached. In this case, as shown in FIG. 5, nails 24 (or screws) are driven into the portion of the roof base fixing portion 14 (same for 13) and fixed to the roof base 23. This nail hole (or screw hole) may be provided in advance.

Next, the rhombus roofing material 10 (B) and the rhombus roofing material 10 (C) are fixed to both diagonal sides of the rhombus roofing material 10 (D). In this case, the lower engaging pieces 17 and 18 of the rhombic roofing material 10 (B) and the rhomboidal roofing material 10 (C) are fitted into the retaining grooves 11 and 12 of the rhombic roofing material 10 (D), respectively, and then, respectively. The roof base fixing portions 13 and 14 are fixed to the roof base 23 by driving nails. After that, the diamond roof material 10 (A) is attached between the adjacent diamond roof materials 10 (B) and 10 (C) by the same procedure. At this time, the front cover portion 20 at the downstream portion of the rhombic roofing material 10 (A) covers the gap between the adjacent rhombic roofing material 10 (B) and the rhombic roofing material 10 (C). Therefore, it is possible to prevent the intrusion of rainwater from the bottom. In addition, the lower half of the diamond-shaped roofing material 10 is used for the uppermost part of the roof, and a roofing material having an appropriate roof base fixing portion on the upstream side is used as needed.

As shown in FIG. 2, the front cover portion 20 has a bottom portion that is bent inward and is not easily scratched on the lozenge-shaped roofing material 10 arranged below even when pressed. However, the molding is complicated. Therefore, as shown in FIGS. 6 and 7, folding portions 25 and 26 having a Z-shaped cross section may be provided at the end portions of the side walls 15 and 16 to form the arc-shaped front cover portion 27. In this case, it is preferable to bend the bottom end of the front cover portion 27 inward, but it is also possible to cut it off, and if necessary, an end cover made of plastic may be provided. In addition, a folded-back portion 27a (shown by a chain double-dashed line in Fig. 6) in which the lower end of the front cover portion 27 is bent inward in the range of 90 to 180 degrees is provided to prevent the lower roofing material from being damaged. Is preferred.

[Effect of device]

 Since the rhomboid roof material according to claims 1 to 3 is provided with the front cover portion on the downstream side, it is possible to cover the gap between the adjacent rhomboid roof materials, whereby rain wind blows from the downstream side of the roof. Even if there is, rainwater does not enter inside. This will prevent leaks and moisture on the roof. In addition, since a backing material is provided on the back side of the roof plate, this provides heat retention and soundproofing effects, and the lozenge-shaped roof material is not easily deformed even when a person is placed on the roof. Particularly, in the diamond-shaped roofing material according to claim 2, since the upstream end of the roof base fixing part is folded back to the surface side, this part is reinforced, and furthermore, the scrap of the plate is not exposed during handling. Don't get hurt. Also, even if there is rainwater that tries to enter the interior due to strong winds, it will be blocked at this part, making it difficult to enter the interior. In the rhomboid roofing material according to claim 3, since the plate material at the tip of the engaging piece is bent by 180 degrees, this portion can be reinforced and the lozenge roofing material can be conveyed by hooking this portion by hand. However, it has the advantage that it is hard to get injured on the edge of the plate.
