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 the roof panels could not cope well 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. A long egress ridge cover is attached along the egress ridge, and a gutter-like portion is formed from both inner ends of the elongated ridge cover, and a mounting portion is provided outwardly from both outer upper ends of the elongated ridge cover. The ends of the horizontal roofing plates facing each other at the lowering part are cut to form a substantially parallel appropriate interval, and the ends of the horizontal roofing plates are positioned on the gutter-shaped part of the lowering ridge cover. , and by inserting a panel door material with a roughly sawtooth shape whose lower surface has the same cross-sectional shape as the horizontal roof, it is watertight. This method solves the above-mentioned problems by being relatively easy to construct, and capable of coping well with thermal expansion and contraction in the longitudinal direction of the horizontal roof panels at the ridge-side-down location.

〔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 10 and the outer engaging part 11 of the horizontal roofing board B, the inner side is lowered inwardly from both ends of the top part 4. A long ridge cover A is provided, which has inward facing parts 5, 5, gutter-like parts 6, 6 formed from both inner ends thereof, and mounting parts 7, 7 provided outwardly from both outer upper ends thereof. It is installed along the said descending ridge, and the opposing horizontal roofing plates B and B ends of the descending ridge part are cut to form an approximately parallel appropriate interval, and the horizontal roofing plates B and B ends are cut. It is provided so as to be located on the gutter-like parts 6, 6 of the egress ridge cover A, and the main plate 9 thereof.
By inserting a side door material 13 formed into a substantially sawtooth shape whose lower surface is the same as the cross-sectional shape of the horizontal roof, the first Secondly, the connecting part of the ridge can be constructed in an extremely watertight manner, secondly, the connecting part can be installed relatively easily and quickly, and thirdly, the heat in the longitudinal direction of the building board B for horizontal roofing can be reduced. Can respond well to expansion and contraction,
Fourthly, it is strong and has the effect of improving architectural beauty.

To explain these in detail, first, a long ridge cover A is attached along the ridge, and the opposing horizontal roof plates B and B ends of the ridge are cut to form approximately parallel appropriate sections. These horizontal roofing plates B are provided so that the ends of B are located on the gutter-shaped parts 6, 6 of the ridge cover A, while forming a gap therebetween, and the main plate 9 thereof is
By inserting a side door material 13 formed into a substantially sawtooth shape whose lower surface is in the same cross-sectional shape as the cross-sectional shape of the horizontal roof, the main plate Even if rainwater tries to infiltrate from the 9th end, the surface door material 13 can act as a rainwater barrier and block it, and even if rainwater infiltrates from there, it will be blocked by the gutter-shaped part 6 of the ridge cover A. Flow down. The water flows out from this gutter-shaped part 6 to the outside on the lower side and does not intrude into the interior, thereby providing a roof repair structure for a horizontal roof with extremely excellent watertightness (rain closure). In this way, in the present invention, since the ridge cover A is particularly arranged with the gutter-like parts 6, 6 on both sides, even if rainwater is strongly trapped in the ridge area, the rainwater will surely flow into the gutter-like part. This has the great advantage of being able to reliably prevent the liquid from flowing down from the parts 6, 6 and infiltrating into the interior.

In the present invention, the ridge cover A is installed, the horizontal roofing boards B are sequentially roofed on this, and the side door material 1 is
3 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 it is configured to have an appropriate interval between the end of the horizontal roof plate B and the hanging part of the gutter-like part 6 of the lower ridge cover A, Even if the horizontal roofing board B is made of a highly elastic material (such as copper), or even if the temperature difference in the area where the horizontal roofing board B is installed is large,
The horizontal roofing board B can absorb thermal expansion and contraction occurring in the longitudinal direction corresponding to the outside temperature at the above-mentioned intervals. Therefore, no thermal stress is generated on the horizontal roofing boards B, B, and even the entire horizontal roofing, and in particular, almost no deformation strain or the like occurs in the main plate 9 of the horizontal roofing board 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 roofing plates B, B are inserted into the U-shaped parts on both sides of the ridge cover A. 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 gradual and progressive way to practice.
