Description

[Detailed Description of the Invention] The present invention relates to a large mountain-shaped roof that is strong against wind pressure, earthquakes, etc. and has an extremely simple structure.

Conventionally, there have been factory-produced chevron roofing materials with long spans (length approximately 15 to 50 m) and large sizes (height approximately 1 to 1.5 m).

If the length is approximately 25 m or more, it is divided into two parts for convenience of transportation.

These large chevron-shaped roofing materials are transported to the site, lifted one by one onto the structure there using a large crane, etc., and placed and fixed between the opposing structural members at the top of the structure. These large chevron-shaped roofing materials are placed side by side and connected with bolts, etc. to form the roof.

When the gable side of this roof (the large chevron roofing materials at both ends of the roof in the direction in which the large chevron roofing materials are installed) receives a horizontal load such as wind pressure, even if it is large, it will not move horizontally because it has a long span. A large amount of flexure occurs, making it impossible to obtain strength, and there are drawbacks such as damage to the member attached to the end side.

Irregular deflections were particularly likely to occur in response to horizontal shakes caused by earthquakes.

For this reason, a truss beam with strong bending rigidity was fixed to the lower part of the large chevron-shaped roof material on the gable side and provided as a reinforcement beam.

Alternatively, a truss was constructed by fixing a large number of members such as braces to the lower part of the roof material.

The above-mentioned reinforcing materials have disadvantages such as a complicated structure, troublesome manufacturing and installation, and high cost as a whole.

Therefore, the present invention is to install a large number of large mountain-shaped roofing materials with bottoms outward from both lower ends of the large mountain-shaped parts on the structural members of the structure, and to connect both side edges of the roofing materials to the structural members at the same time. The large chevron roofing material near the gable side of the roof is fixed, and by connecting the plates between the bottoms of the large chevron section and over the entire length of the large chevron section, wind pressure is reduced on the gable side of the roof. When a horizontal load such as the above is applied, the roof material on the gable side becomes extremely strong, and the board plays the role of a ceiling board. Moreover, the structure is simple and can be provided at low cost, eliminating the above-mentioned drawbacks.

The configuration will be explained with reference to the drawings.

A is a large chevron roofing material with a long span, and bottom portions 2, 2 are formed outwardly from both lower ends of the large chevron portion 1 (approximately trapezoidal mountain shape).
An inclined edge 3 is formed outwardly and upwardly from the outer end of the bottom part 2, and an inclined edge 3' is formed upwardly inwardly from this upper end.
are integrally formed.

Reference numeral 4 refers to the supporting bones, which are the chevron portions 1 of this large chevron roofing material A;
The cross-sections have substantially the same shape as the bottom parts 2, 2 and the inclined edges 3, 3, and a plurality of them are fixed to the lower surface at predetermined intervals in the longitudinal direction.

L-shaped metal fittings 5, 5 are fixed to both bottom ends of this force bone 4.

Reference numeral 6 denotes a plate, which is fixed over the entire length of the large-sized chevron-shaped roofing material A so as to connect the bottom parts 2, 2.

This plate body 6 is provided on the large-sized chevron-shaped roof material A as required.

The force bone 4 and the upper metal fitting 5 protrude from the notch at the end of the plate body 6.

A heat insulating material, a decorative board, a lighting fixture mounting material, etc. are previously attached at a factory to the inner surface of the large-sized chevron-shaped roofing material A that is not provided with the plate 6, but these are omitted in the drawing.

Further, even if the plate body 6 is attached, a heat insulating material, etc. (not shown) is provided.

A large number of large-sized chevron-shaped roofing materials A (without plates 6) and large-sized chevron-shaped roofing materials A with plated bodies 6 are installed side by side on opposing structural members 7 at the upper part of the structure to form a roof.

The large chevron roofing material A with the plate body 6 is provided one or more (two in the drawing) on the gable side of the roof (both ends of the roof in the direction perpendicular to the large chevron roofing material A) or near the gable side, and The middle part is covered only with large chevron roofing material A.

The inclined edges 3', 3' of the large-sized chevron-shaped roofing materials A, A are fastened and connected by a cap material 8.

9 is the wall on the gable side of the structure. Next, the effects will be explained.

In this invention, a large number of large chevron roofing materials A are installed on the upper part of the structure, and large chevron roofing materials A are installed near the gable side of the roof.
By connecting the bottom parts 2 and 2 with the plate 6, the space between the bottom parts 2 and 2 is the lower ends of the large chevron, and the gap between them is large, and the wide plate 6 is connected there. The plate 6 and the large chevron roofing material A have a trapezoidal cross section and a large section modulus. By installing the large chevron roofing material A with 6 near the gable side of the roof, it is difficult to bend in the horizontal direction even with long spans, and the gable side can be made extremely strong. There is no need to provide a truss beam, the structure of the plate 6 is extremely simple, it is easy to install, the plate 6 also serves as a ceiling plate for the large mountain-shaped roof A, and the appearance is good, and the present invention is extremely inexpensive. It can be provided to
