Description

[Detailed Description of the Invention] [Field of Industrial Application] The present invention is directed to horizontal roofs that have a relatively simple ventilation structure, are easy to construct, and have good rain protection (watertightness). Regarding the above-water side repair structure for ventilation.

[Conventional technology and its problems]

Conventional horizontal roof roofs have been repaired on the water side, such as at the ridge and wall joints, by attaching ridge wrapping materials or wall joint sluices, but the structure is generally complex and construction is troublesome. Furthermore, when the water side was the ridge, there were drawbacks such as strong wind and rain hitting this area and poor watertightness. In addition, there is a demand for a ventilation structure in areas above the water due to problems such as internal condensation.

[Means for solving problems]

Therefore, the inventor worked diligently to solve the above problem.
As a result of repeated research, the present invention has been developed to form a rising part from the bottom piece attachment part in a horizontal roof that is constructed by engaging the inner engaging part and the outer engaging part of the horizontal roof plate. The locking part of the composite mounting bracket, which is integrally formed with a locking part on the front side of the upper end and a top piece mounting part whose height becomes higher on the rear side, is attached to the horizontal roof plate at the most above water position of the horizontal roof. The bottom piece attachment part is fixed to the support member while being locked to the inner engaging part of the upper part, and a hanging part is formed from one side of the upper surface part, and a bent edge is formed inward from the lower end of the water cutting material. upper surface part and hanging part,
The bending edge has a hollow part and is provided so as to cover the inner engaging part at the water side position, and the upper surface part is fixed to the top piece mounting part of the composite mounting bracket, which makes it relatively simple. This solves the above-mentioned problems by providing a ventilated structure, good workability, and good rain protection (watertightness).

〔Effect of the invention〕

In the present invention, in a horizontal roof that is constructed by engaging the inner engaging part 4b and the outer engaging part 4c of the horizontal roofing board 4, the rising part 8 is raised from the bottom piece attachment part 7.
The locking part 9 of the composite mounting bracket A is integrally formed with a locking part 9 on the front side of the upper end and a top piece mounting part 10 whose height is higher than that on the rear side. The bottom piece attachment part 7 is fixed to the support material 2 while being locked to the inner engaging part 4b of the horizontal roofing board 4 located above the water, and the part 14 hanging down from one side of the upper surface part 13
The upper surface part 13 and the hanging part 1 of the water-side draining material B have a bent edge 15 formed inward from the lower end.
4. The bent edge 15 has a hollow part 17 and is provided so as to cover the inner engaging part 4b at the water side position, and its upper surface part 13 is fixed to the top piece mounting part 10 of the composite mounting bracket A. As a result, firstly, it is extremely easy to modify the above-water side for ventilation, secondly, it is easier to construct, and thirdly, rain protection (watertightness) can be improved. .

To explain these in detail, the composite mounting bracket A has both a hanger for attaching the horizontal roofing board 4 and a receiving bracket for attaching the above-water side drainage material B, which serves as a ridge wrapping material and a wall joining member. Since it is a single member, repairs on the water side using this can be made extremely simple.

Conventionally, at least two members were required to construct such a structure, but the present invention has the great advantage that it can be easily constructed using only a single member. This allows the repair to be carried out relatively inexpensively.

In addition, only the water-side drainage material B serves as a ventilation member, and good ventilation can be achieved by the inflow and outflow of air from the hollow part 17. In this way, by using a composite mounting bracket A with only a higher height of the top piece mounting portion 10, it can be easily installed on the water side for ventilation, which is an epoch-making effect.

Also, since it is so easy to install,
By simply attaching the composite mounting fitting A, which is a single member, to the support member 2, it is possible to attach the hanger and the receiving fitting at the same time, which has the effect of significantly improving workability.

Furthermore, by providing the upper surface portion 13 and the bent portion 15 of the hanging portion 14 of the water-side draining member B so as to cover the inner engaging portion 4b at the water-side position, the hollow portion 17 is configured. However, the presence of the bent portion 15 can prevent rainwater from entering from the hollow portion 17.

In addition, by fixing the upper surface part 13 of the water-side drain member B to the top piece attachment part 10 of the composite mounting bracket A, it is the same as attaching it to a strong hanger, and the water-side part is made relatively strong. It can be configured as follows.

As shown in FIGS. 4 and 5, by providing the water return material 21, it is possible to reliably prevent rainwater from entering from the 17 empty spaces. Further, as shown in FIG. 6, if a mesh plate 22 is provided, insect-proof, dust-proof, snow-proof, etc. effects can be achieved. Furthermore, by providing the leg portion 11 at the end of the top piece attachment portion 10 of the composite mounting bracket A, the composite mounting bracket A can be made even stronger, and the above-water side repair structure can also be made stronger.
