[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.

[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 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 is integrally formed with the locking part on the front side of the upper end and the top piece mounting part on the rear side.
The above water side, which is fixed to the inner engaging part of the horizontal roof board at the position closest to the water side of the horizontal roof and whose bottom piece attachment part is fixed to the supporting material, forming a part hanging down from one side of the upper surface part. The upper surface part and the hanging part of the gutter cover the inner engaging part at the water side position, and the lower end of the drooping part is positioned on the main plate of the horizontal roofing board, and the upper part is attached to the composite mounting bracket. The water-side repair structure of the horizontal roof that is fixed to the top piece attachment part allows for an extremely simple construction, good workability, and good rain closure (watertightness), which solves the above problems. It is.

〔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 7 is formed from the bottom piece attachment part 6.
A composite mounting bracket A in which a locking part 8 is integrally formed on the front side of the upper end and a top piece mounting part 9 is integrally formed on the rear side of the upper end.
The locking part 8 of the horizontal roof is secured to the inner engaging part 4b of the horizontal roof board 4 located on the water side of the horizontal roof, and the bottom piece attachment part 6 is fixed to the supporting material 2.
The upper surface part 12 and the drooping part 13 of the water-side draining material B which has a drooping part 13 formed thereon from one side cover the inner engaging part 4b at the water-side position, and the drooping part 1 thereof
3. Position the lower end on the main plate 4a of the horizontal roofing plate 4,
Moreover, by fixing the upper surface part 12 to the top piece mounting part 9 of the composite mounting bracket A, firstly, the structure can be extremely simple, secondly, workability can be improved, and thirdly,
It also has the effect of improving rain protection (watertightness).

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.

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.

Further, while covering the inner engaging portion 4b with the upper surface portion 12 and the hanging portion 13 of the above-water side gutter B, the lower end of the hanging portion 13 is connected to the main plate 4 of the horizontal roofing board 4.
By locating it above a, it is possible to suitably provide rain protection (watertightness) for repairs on the water side such as ridge parts and wall joint parts. In other words, the hanging portion 13 acts as a dam for rainwater, making it extremely difficult for rainwater to enter. Even if rainwater does infiltrate, a hollow section is formed inside by the water-side draining material B, so that capillary action will not occur. It is possible to reliably prevent water from entering the room. Furthermore, such a simple and watertight structure can provide effects such as soundproofing, dustproofing, insectproofing, and snowproofing.

In addition, by fixing the upper surface part 12 of the water-side water cutting material B to the top piece mounting part 9 of the composite mounting bracket A,
This is similar to attaching it to a strong hanger, and the part on the water side can be made relatively strong.

In addition, by providing the leg part 10 at the end of the top piece attachment part 9 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. In addition, if the above-water drainage material B having an arc-shaped part as shown in Fig. 5 is used, the steel structures will not vibrate independently relative to the concrete structure, or the steel structures will be subject to thermal expansion and contraction. However, within the allowable range of elasticity of the arc-shaped portion, these can be absorbed and a strong installation can be achieved.
