Description

[Detailed Description of the Invention] [Industrial Application Field] The present invention allows for watertight construction, relatively simple construction, and thermal expansion and contraction in the longitudinal direction of horizontal roofing panels at the exit point. This invention relates to a ridge repair structure for side-roofed roofs that can be well adapted to.

[Conventional technology and its problems]

Conventionally, when repairing the ridge part of a horizontal roof, a ridge wrapping material or the like is attached, but the structure is generally complicated and the construction is troublesome. In addition, there were drawbacks such as spoiling the aesthetic appearance. Additionally, there were drawbacks such as strong wind and rain at the point where the ridge was dropped off, and poor watertightness. In addition, there was also the drawback that it was not possible to adequately cope with thermal expansion and contraction in the longitudinal direction of the horizontal roof panels at the point where the ridge fell.

[Means to solve the problem]

Therefore, the inventor worked diligently to solve the above problem.
As a result of repeated research, the present invention has been applied to the lower ridge of a horizontal roof, which is constructed by engaging the inner engaging part and the outer engaging part of the horizontal roof shingles. An elongated descending member, which has an inward facing part, a hanging part from both inner ends, a bottom part outward from both lower ends, and a folded edge above both outer ends. A ridge cover is attached along the lower ridge, and the opposite ends of the horizontal roofing plates at the lowering point are cut to form a substantially parallel appropriate interval, and the ends of the horizontal roofing plates are connected to the lowering ridge. Provided so as to be located on the bottom part of the cover, and between the main plate end and the inward part of the ridge cover, formed into a substantially sawtooth shape so that the lower surface has the same cross-sectional shape as the horizontal roof. By inserting the side door material, water-tight construction is possible, the construction is relatively simple, and it can cope well with thermal expansion and contraction in the longitudinal direction of the horizontal roof panels at the drop-off point, which solves the above problems. It is resolved.

〔Effect of the invention〕

In the present invention, in the lower ridge of the horizontal roof, which is constructed by engaging the inner engaging part 11 and the outer engaging part 12 of the horizontal roofing board B, the lower inward direction from both ends of the top part 4 is applied. Inward facing portions 5, 5 are formed, hanging portions 6, 6 are formed from both inner ends thereof, bottom portions 7, 7 are provided outwardly from both lower ends, and folded upward from these two outer ends. A long ridge cover A with edges 8, 8 formed thereon is attached along the ridge, and the opposing horizontal roofing plates B at the ridge part are cut at the ends of B so as to be approximately parallel to each other at appropriate intervals. The horizontal roof plates B are provided so that the ends of B are located on the bottom surfaces 7, 7 of the ridge cover A, and the upper end of the main plate 10 and the inward facing part 5 of the ridge cover A are formed. By inserting a side door material 14 whose lower surface is roughly sawtooth-shaped so that the cross-sectional shape is the same as the cross-sectional shape of the horizontal roof, firstly, the connection part at the point where the ridge falls is made extremely watertight. Second, it is relatively easy and quick to install the connection points, thirdly, it can respond well to thermal expansion and contraction in the longitudinal direction of the horizontal building board B, and fourth, it is strong. , it has effects such as improving the architectural aesthetics.

To explain these in detail, first, the long ridge cover A is installed along the ridge, and the opposing horizontal roof plates B and B ends of the ridge are cut off to form approximately parallel sections. The horizontal roof plates B are provided so that the B ends are located on the bottom surfaces 7, 7 of the lower ridge cover A, while forming a gap between the main plate 10 and the inner side of the lower ridge cover A. By inserting a panel door material 14 whose lower surface is formed into a substantially sawtooth shape so that the cross-sectional shape is the same as that of the horizontal roof, even if rainwater tries to enter from the end of the main plate 10, it will be prevented from entering. The side door material 14 can be used as a barrier to block rainwater, and even if rainwater enters from there, it will flow down to the bottom part 7 of the ridge cover A. Since this bottom part 7 has a hanging part 6 and a folded edge 8 formed on both sides, it plays the role of a gutter, and the water flows out to the outside below the water and does not penetrate inside, making it extremely watertight ( It is possible to provide a ridge repair structure for horizontal roofs with excellent rain protection.

In the present invention, the ridge cover A is attached, the horizontal roofing boards B are sequentially roofed on this, and the side door material 1
4 is inserted, and has the advantage that the structure is relatively simple and the construction can be relatively simple and quick.

Furthermore, at the connecting part of the lower ridge, since the end of the horizontal roof plate B and the hanging part 6 of the lower ridge cover A are configured to have an appropriate distance, the horizontal roof Even if the roofing board B is made of a highly elastic material (copper, etc.), or the horizontal roofing board B
Even if there is a large temperature difference in the region where the roof is installed, the horizontal roofing sheets B can absorb the thermal expansion and contraction that occurs in response to the outside temperature in the longitudinal direction at the above-mentioned intervals. Therefore, no thermal stress is generated on the horizontal roof panels B, B, and even the entire horizontal roof, and in particular, almost no deformation strain occurs in the main plate 10 of the horizontal roof panels B exposed on the outer surface. Can be done. This makes it possible to create a strong connection structure in which almost no deformation strain occurs even when subjected to external forces such as earthquakes, and it is possible to prevent the conventional reduction in strength due to strain generation and the plate rattling phenomenon.

In addition, in the present invention, a ridge cover A with a large section modulus is arranged at the ridge lowering point, and the ends of the horizontal roof plates B, B are inserted into the U-shaped portions on both sides of the ridge cover A, so that Even when large wind pressure is applied, the edges of the horizontal roofing plate B will not come off, making it highly durable. Furthermore, this allows construction to be carried out at the point where the horizontal roof falls. It can also be used as a completely innovative way to train.
