[Industrial applications]

 The present invention relates to a support structure for a metal plate roof on an asbestos corrugated slate roof, and in particular, a new roof for forming a metal plate roof on the upper surface of an existing roof of the asbestos corrugated slate roof without any modification. Related to the support structure of.

[0002]

[Prior Art]

 For buildings such as factories and warehouses that do not directly affect the habitability, a main building is installed in the hut structure and the asbestos slate that is formed into a corrugated shape without the use of floor boards is directly roofed. It is possible to obtain a perfect roof structure, and the asbestos slate as a building material is easy to process on site and has excellent fire resistance. It also adopts a dry structure and is well adapted to the prefabricated construction method. Asbestos corrugated slate roofs are widely used because of their advantages.

However, in the conventional support structure for a metal plate roof on an asbestos corrugated slate roof, even if it is common to follow that the purlins are arranged at a predetermined interval in parallel with the ridge and the eaves, the existing roof is used. Since the roof surface of the new roof is wavy, the arrangement and support of the members above the roof of the new roof are not compatible with both the direction of the flow of the roof and the direction perpendicular thereto, and are left as a blind spot of the roof structure. It can be said that no suitable support structure is known.

[0004]

[Problems to be solved by the device]

 On the other hand, recently, a situation has emerged in which the carcinogenicity of the raw material asbestos itself has become a problem, and this problem has come to the fore in the spraying method of steel fire-resistant coating materials. As for the processing of materials for asbestos slate thatched roofs, asbestos scattering is not regarded as a particular problem, including the stage of renovation work, but the workers involved in the construction are becoming more concerned about occupational diseases. However, it is considered that the impact directly affects the ups and downs of conventional asbestos corrugated slate roof construction. Since such a roof structure has a wide range of conventional applications, there are many opportunities for renovation work, especially in factory construction, where renovation work is required while continuing internal operations. , The solution was desired.

[0005]

[Means for Solving the Problems]

 In view of the above problems, the present invention allows the renovation work to be carried out while the operation of the factory etc. is continued by using the existing roof as it is as a groundwork. Focusing on its reasonableness, it was created for the purpose of providing a supporting structure for a metal plate roof on an asbestos corrugated slate roof, which is provided on the upper surface of the existing roof of the asbestos corrugated slate roof. In a support structure for a metal plate roof on an asbestos corrugated slate roof when forming a new roof using a metal roof plate in a horizontal direction, a metal roof is constructed on the upper surface of the existing roof. The support washer supporting the additional member is arranged, and the support washer consists of the base and the pillow seat mounted on the base, and the base is composed of the leg and the upper edge of the asbestos corrugated slate. Trapezoidal with a top plate that extends over the mountains The pedestal has a hat-shaped cross section with a flange in the direction of the top plate of the base, and the top plate of the base and the flange of the pillow are assembled by screws, The lower end of the screw penetrates the mountain portion of the lower asbestos corrugated slate, reaches the purlin and is fixed, and a new roof with a metal plate is constructed on the upper surface of the pillow.

[0006]

[Work]

 Therefore, according to the present invention, in a roof in which a metal roofing board is used in a horizontal direction and the roofing board is laterally roofed, a new roof with a metal roofing board is formed by directly using the existing roof of asbestos corrugated slate roofing as a base. However, the drawbacks associated with asbestos corrugated slate are eliminated from the viewpoint of carcinogenic hygiene and health problems as well as from the viewpoint of strength and other properties of building materials, and asbestos is prevented from scattering during repair work. In addition, the addition of a base plate to the slate or thatched roof improves the heat insulation performance and forms a support space for the supporting washers between the existing roof and the new roof. Ventilation or insulation structures formed on the roof can result in significantly improved specifications for the roof of a building. Furthermore, each part of the support washer consisting of two parts, upper and lower, is attached only by fixing to the existing roof, and not only is the assembly easy, but there is also the freedom of design change in the structure of the upper and lower two parts. The large size is another advantage that can be applied to the existing roof structure.

【Example】

 The details of the roof support structure of the present invention will be described with reference to the drawings illustrating an embodiment. FIG. 1 is a perspective view of a support washer used for a support structure of a metal plate roof on an asbestos corrugated slate roof of the present invention, and FIGS. 2 and 3 are respectively constructed by using the same metal. It is a front view of the support structure seen from the roof flow direction and a side view of the support structure. 2 and 3, the existing roof 1 of the asbestos corrugated slate roof has a roof plate of the asbestos corrugated slate 7 stretched vertically on a purlin 2 of C-shaped channel steel, and the flange of the upper side of the purlin 2 is extended. The hook 81 of the hook bolt 8 is hooked on, and the threaded portion 83 at the upper end of the main body portion 82 is penetrated through the upper surface of the asbestos corrugated slate 7 at the position of the mountain portion 71, so that the curved washer 84 and the nut 85 are fitted to the curved surface of the mountain portion 71. It was raised using and.

[0008] On the upper surface of the existing roof 1 of asbestos corrugated slate roof, to roof the new roof 10 by using the metal roof plate sideways, on the upper surface of the existing roof 1 stretched with the roof plate of the asbestos corrugated slate 7. , The support structure 11 for the new roof 10 is formed by leaving the existing roof 1 as it is. The support structure 11 is provided with a support washer 12 for supporting an additional member that constitutes a metal roof from the roof 3 to the roof plate 6 above the existing roof 1, and the support washer 12 is shown in FIG. As shown, it comprises a base 20 and a pillow 30 mounted on the base. The pedestal portion 20 has a leg portion 21 and a side wall portion 22 above the leg portion 21 in parallel with the adjacent valley portions 72 on the upper surface of the asbestos corrugated slate 7, and the top portions of the side wall portions 22 are connected to each other to form a mountain of the asbestos corrugated slate 7. It is composed of a top plate 23 that straddles the portion 71. One side edge 24 of the top plate 23 of the base portion 20 is linear, but an engaging portion 25 is formed by folding back on the upper surface side on the other opposing side.

The pillow base 30 fixed on the base 20 has a hat-shaped cross section perpendicular to the base 20 so as to be supported on substantially the entire top plate 23 and has an upper surface 31. And side walls 32 and flanges 33 on both sides. An engaging portion 34 is formed by folding back on the lower surface side at the end edge of one flange 33 so as to receive the linear side edge 24 of the base portion 20 and the other flange 33 of the other flange 33. The edge is directly received by the engaging portion 25 of the base.

When the pillow 30 is assembled on the pedestal 20, the screw 27 is inserted into the bolt hole 35 common to the flange 33 of the pillow 30 and the top plate 23 of the pedestal 20, and the screw 27 below it is inserted. The asbestos corrugated slate 7 is passed through the mountain portion 71 to reach the purlin 2 and fixed. Self-drilling screws are used for screws 27. At this time, in the support washer 12, the pillow 30 is erected in the shape of a beam on the top plate 23, and the top plate 23 and the flange 33 are provided with the engaging portions 25 and 34, respectively. This prevents the top plate 23 from bending downward during the fixing work of the self-drilling screw.

Next, the slack 3 is supported on the upper surface 31 of the pillow base 30, and between the slacks 3, the ground board 4 made of a wood wool cement board having the same thickness as the height of the slack 3 is dropped. The asphalt roofing waterproof sheet 5 is stretched on the upper surface of the base plate 4, and the metal roof plate 6 is horizontally used on the upper surface to fit the upper side engaging portion 61 and the lower side engaging portion 62. The supporting structure for a new metal sheet roof with an existing asbestos corrugated slate roof as a base is completed.

Various deformation designs are possible for the support washer used in the support structure. The support washer 13 shown in FIG. 4 is similar in structure to the support washer 12, but the top plate 23 of the base 20 does not have the engaging portion 25 as shown in FIG. In this example, one of the flanges 33 of the seat 30 is fixed with a screw 30a. The support washer 14 shown in FIG. 5 is an example in which the base 20 and the pillow 30 are continuously and integrally formed from a single material, and if explained by the member names of FIG. One side of the top plate 23 and one side edge of the flange 33 of the pillow 30 are integrally continuous with each other, and a part of a single steel plate is cut off without forming a folded back engaging portion with each other. However, it is an example of being formed by bending in a predetermined direction.

The support washer 15 shown in FIG. 6 is an example in which the combination of the base 20 and the pillow 30 is formed almost the same as the support washer 12 of FIG. 1, but each is provided as an independent member. As described above, it is manufactured separately. A notch 26 is formed on one side of the top plate 23 of the pedestal 20, and a similar notch 36 is formed on the flange 33 of the pillow 30 on the side not having the engaging part 34. Regardless of the length of the threaded portion 83 of the hook bolt 8 protruding from the mountain portion 71 of the asbestos corrugated slate 7 of the existing roof 1, consideration is given to the new roof 10 being formed on the support structure 11 and the construction site. Assembly in is easily accomplished by sliding in one direction.

A method of constructing a support structure for a metal plate roof on an asbestos corrugated slate roof according to the present invention will be described with reference to FIGS. 1 to 3. In FIG. 1, first, the support washer 12 is formed by bending a base 20 and a pillow 30 from steel plates, and the base 20 and the pillow 30 are arranged in this order on the upper surface of the asbestos corrugated slate 7 of the existing roof 1. Here, the support washer 12 is fixed to the purlin 2 using the self-drilling screw 27. On the other hand, in the middle of the tartar 3, the ground board 4 made of wood wool cement board is dropped, and the tarpaulin 5 such as asphalt roofing is laid on it, and the roof board 6 is laid on the tarpaulin. The existing roof 1 of slate roof is used as a base as it is, and a new roof 10 is completed on the upper surface of the roof with a supporting structure of a metal plate roof.

The support structure of the metal plate roof on the asbestos corrugated slate roof of the present invention is not limited to the above-mentioned embodiment, and the shape of the support washer, the base 20 and the pillow 30 are not limited to the above. Various design changes can be made to the combination and the like. Further, the space formed between the existing roof 1 and the new roof 10 is newly constructed by being insulated by the roof plate of the asbestos corrugated slate 7 and the base plate 4 of wood wool cement plate. A ventilation structure can be formed by connecting the attic from the top of the building to the outside. Further, as shown in FIG. 1, when the slack 3 is arranged, this space can be filled with glass wool 40 to enhance the heat insulating effect.
