Next, a second embodiment of the present invention will be described. This second embodiment has a particularly constructed wall joint construction as shown in Figs. 4 and 5, and many of its constituent members are the same as those of the first embodiment. The symbol shall be given as follows. Particularly in the case of the second embodiment, it corresponds to the wall material 16 or the wall portion 17 of the reinforced concrete structure, and serves as a wall joining member, and this

"Effect of the Invention J In the present invention, in a horizontal roof that is constructed by engaging the lower part 4b and the upper part 4C of the horizontal roofing board 4, the rising part 7 is formed from the bottom attachment part 6. Then, the suspender retaining part 8 of the composite mounting bracket A, in which the suspender retaining part 8 is integrally formed on the front side and the top side attaching part 9 is integrally formed on the rear side of this upper end, is attached to the most water-side position of the horizontal roof. The upper surface of the above-water side gutter B, which has a base attachment portion 6 fixed to the support member 2 while being locked to the lower edge portion 4b of the horizontal roofing board 4, and a hanging portion 13 formed from one side of the upper surface portion 12. The lower part 4b at the above water side position in the part 12 and the hanging part 13
The lower end of the hanging portion 13 is substantially in contact with the main plate 4a of the horizontal roofing board 4 while the upper surface portion 12 is fixed to the top side mounting portion 9 of the composite mounting bracket A. It has the following effects: it can be constructed extremely easily, secondly, it has good workability, and thirdly, it has good 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, it can be used to repair water on both sides with an extremely simple structure.

Conventionally, such a configuration requires at least two
However, 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 simple, the installation can be done by simply attaching the composite mounting bracket A, which is a single member, to the support material 2.
It is possible to attach the hanger and the bracket at the same time, which has the effect of significantly improving workability.

Furthermore, the upper surface portion 12 and the hanging portion 13 of the above-water side flashing material B cover the lower part 4b, and the lower end of the hanging portion 13 is substantially in contact with the main plate 4a of the horizontal roofing board 4. This makes it possible to suitably protect against rain (watertightness) in areas above water such as ridges and wall joints. In other words, the hanging portion 13 acts as a weir for rainwater, making it extremely difficult for rainwater to enter. Even if rainwater does infiltrate, a void is formed inside by the water-side draining material B, so that capillary action is prevented. It is possible to reliably prevent it 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 draining material B to the top mounting part 9 of the composite mounting bracket A, it is the same as attaching it to a strong hanger, and the water-side part is constructed relatively firmly. can. Furthermore, if the part on the water side is the ridge, the wind force coefficient in architectural engineering is several times higher at the ridge than at the middle part of the roof, but this can be made sufficiently satisfying.
Furthermore, it can sufficiently withstand snow loads.

In addition, by providing the leg portion 10 at the end of the top mounting portion 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 strengthened. 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.
