Description

[Detailed description of the invention] [Industrial application field] The present invention is a large-sized chevron roof that has an extremely simple structure and can prevent the noise caused by the thermal expansion and contraction of large-sized chevron roofs due to changes in outside temperature. This invention relates to a structure for preventing noise at a connecting part of a roof.

[Conventional technology and its problems]

Conventionally, in the construction of large-sized chevron roofs with long spans, the L-shaped metal fittings at both lower ends of the struts provided at predetermined intervals on the underside of the large-sized chevron roofing material are fastened to the L-shaped metal fittings of the adjacent large-sized gabled roofing material. The structure is such that they are connected using metal fittings.

The large mountain-shaped roof has a so-called soft structure that prevents external forces from concentrating on it, making the whole building strong. Therefore, the connecting portions of the large-sized chevron roofing materials in the width direction are not fixed, and each of the large-sized chevron-shaped roofing materials is configured to be able to expand and contract independently.

However, if the adjacent large mountain-shaped roof expands and contracts due to changes in outside temperature, the difference in the amount of expansion and contraction will cause misalignment between the L-shaped fittings, causing noise and causing discomfort to residents. There was a problem.

[Means for solving problems]

Therefore, as a result of intensive research to solve the above-mentioned problems, the inventor has devised the present invention by installing reinforcement bones with approximately the same cross-section as this on the lower surface of the roof skin material at predetermined intervals in the longitudinal direction. A large chevron roofing material is created by fixing multiple pieces of L-shaped metal fittings so as to wrap around the inclined edges of both ends of the strength bones, and by installing a large number of these large chevron-shaped roofing materials on top of the structural material, both adjacent L-shaped metal fittings can be used simultaneously. The above-mentioned problem was solved by creating a noise-preventing structure for the joints of large-sized mountain-shaped roofing materials with synthetic resin tape interposed between the rising parts, thereby solving the noise phenomenon caused by thermal expansion and contraction of large-sized mountain-shaped roofs. It is.

[Effect of idea]

In the present invention, a plurality of reinforcement ribs 2 having substantially the same cross section as the roof skin material 1 are fixed at predetermined intervals in the longitudinal direction to the lower surface of the roof skin material 1, and the inclined edges 2c, 2c at both ends of the reinforcement bones 2 are covered. The L-shaped metal fittings 3, 3 are fixed together to form a large-sized chevron roofing material A.
A large number of these are installed on the structural members 5, 5, and a synthetic resin tape 8 is interposed between the two rising parts 3a, 3a of both adjacent L-shaped metal fittings 3, 3 to create a noise prevention structure at the connection part of the large mountain-shaped roof. As a result, firstly, the noise phenomenon between the L-shaped fittings 3, which are the connecting parts, can be prevented, and secondly, the rising part 3a of the L-shaped fittings 3 is in the form of a flat plate, so that it is possible to prevent both the facing parts. The synthetic resin tape 8 interposed between the upper parts 3a, 3a is difficult to come off,
Thirdly, the structure is simple and it is extremely easy to construct.

To explain these effects in detail, the first
Furthermore, due to the relationship between the shape of the large-sized chevron roofing material A and the angle of solar radiation, there is often a significant temperature difference between the right side and left side of the chevron-shaped cross section of the large-sized chevron-shaped roofing material A. For this reason, the L-shaped metal fittings 3, 3 at the connecting part of the adjacent large-sized chevron-shaped roofing materials A, A.
During this period, a shift occurs due to the difference in expansion and contraction, and at this time, the sound of the rising portions 3a, 3a rubbing against each other often becomes a noise, causing discomfort to the occupants.

For this reason, in the present invention, since the synthetic resin tape 8 is interposed between the rising parts 3a, 3a of the L-shaped fittings 3, 3, the rising parts 3a, 3a do not come into direct contact with each other, but shift relative to each other. Therefore, it is possible to prevent the noise generated when the metals shift relative to each other, and since the synthetic resin tape 8 also has the effect of absorbing vibrations, albeit slightly, it is possible to prevent the noise phenomenon extremely well.

Second, the rising portion 3a is flat, and even if the L-shaped fittings 3, 3 shift relative to each other, most of the synthetic resin tape 8 remains on the rising portion 3a.
Since it is sandwiched between a and 3a, it does not easily come off from the L-shaped fittings 3, 3, and therefore the effect of preventing the noise phenomenon can be maintained for a long period of time.

Thirdly, the structure of the present invention is extremely simple, that is, the large-sized chevron roofing material A,
Just by installing A, . . . together, the effect of preventing the noise phenomenon can be achieved.

Therefore, the construction work can be carried out almost the same as the conventional roofing work for large-sized chevron roofs.
