Description

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

[Conventional technology and its problems]

BACKGROUND ART Conventionally, large-sized chevron roofs have been constructed by installing a large number of long-span large-sized chevron-shaped roofing materials between opposing beams at the top of a structure.

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, when adjacent large-sized chevron roofing materials thermally expand and contract due to changes in outside temperature, the difference in the amount of expansion and contraction causes misalignment between the joints of the large-sized chevron-shaped roofing materials, causing large noises and other problems. This caused problems such as discomfort caused to residents.

[Means for solving problems]

Therefore, as a result of intensive research to solve the above-mentioned problems, the inventor has developed the present invention by forming an inclined edge outwardly upward from both bottoms of the chevron-shaped portion, and extending upwardly inwardly from the upper end of the inclined edge. A large chevron-shaped roofing material is obtained by fixing reinforcing bones that have approximately the same cross-sectional shape as this cross-section at predetermined intervals in the longitudinal direction to the lower surface of the roof skin material with an edge formed on the edge, and then attaching this large-sized chevron-shaped roofing material to the structural material. Noise noise at the exterior joints of large mountain-shaped roofs that are installed in large numbers, and where synthetic resin tape is interposed between the intersections of the sloped edges and edges of adjacent large-sized mountain-shaped roof materials, and cap material is fitted between the edges. The preventive structure prevents the noise phenomenon caused by thermal expansion and contraction of a large mountain-shaped roof, thereby solving the above-mentioned problems.

[Effect of idea]

In the present invention, both bottom portions 1 of the chevron-shaped portion 1a
Slanted edges 1c, 1c facing outward and upward from b, 1b
, and on the lower surface of the roof skin material 1 on which edges 1d, 1d are formed inside and above the upper ends of the inclined edges 1c, 1c, reinforcement bones 22 having substantially the same cross section as this are placed at predetermined intervals in the longitudinal direction. Large chevron roofing material A
A large number of large-sized chevron-shaped roofing materials A are installed on the structural members 5, 5, and the intersections 1e,
First of all, by creating a noise-preventing structure for the exterior connection part of a large mountain-shaped roof in which a synthetic resin tape 8 is interposed between 1e and a cap material 9 is fitted between the edges 1c and 1c. A certain intersection 1
It is possible to prevent the noise phenomenon that occurs between e and 1e, and the intersection part 1e of the second adjacent large-sized chevron roofing materials A,
By interposing the synthetic resin tape 8 between 1e, watertightness becomes extremely good, and thirdly, it is possible to prevent the noise phenomenon with an extremely simple structure.

To explain these effects in detail, the first
Furthermore, since a large mountain-shaped roof has a mountain-shaped cross section, there is often a significant temperature difference between the right sloped side and the left sloped side of the mountain-shaped portion 1a depending on the direction and angle of solar radiation.

For this reason, the amount of thermal expansion and contraction of the two intersection parts 1e, 1e, which are the exterior connecting parts of the adjacent large-sized chevron roofing materials A, A, is different, and a relative displacement effect occurs between the two intersection parts 1e, 1e. .

At this time, the two intersections 1e, 1e often rub against each other, producing noise and causing discomfort to the occupants. Synthetic resin tape 8 between
Since the intersecting parts 1e and 1e do not come into direct contact with each other, and the intersecting parts 1e and 1e shift and move with the synthetic resin tape 8 in between, there is no friction noise between metals, which is extremely good. It is possible to prevent the noise phenomenon.

Second, by interposing the synthetic resin tape 8 at the intersections 1e, 1e, which are the exterior connecting parts of the adjacent large-sized chevron roofing materials A, A, both intersections 1e,
Since the tapes 1e are in close contact with both sides of the synthetic resin tape 8, the area between the two intersections 1e and 1e is extremely watertight, which is effective in blocking the infiltration of rainwater and the like.

Thirdly, the structure of the present invention is extremely simple, that is, the synthetic resin tape 8 is simply interposed between the opposing intersections 1e, 1e of the adjacent large-sized chevron roofing materials A, A. The synthetic resin tape 8 can be attached to the intersection 1e of the large-sized chevron roofing material A both in the factory and on-site, and therefore the construction can be carried out almost unchanged from the conventional roofing work for large-sized chevron roofs. Furthermore, the present invention can be provided at an extremely low cost.

In addition, by interposing the synthetic resin tape 8 between the L-shaped metal fittings 3, 3, it is possible to reliably prevent noise at the joint between the large-sized chevron roofing materials A and A.
