BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a drainage device in a building assembled such as an approach.

[0002]

2. Description of the Related Art Conventionally, for example, an approach drainage system is
Plastic gutter members for structural materials such as beams and columns,
It was known that the gutter was provided by the so-called interior method by attaching it by so-called external attachment, or by making a hole in the structural material such as beams and columns, or by providing a water passage inside the structural material. .

[0003]

However, when the above-mentioned conventional plastic gutter member is externally attached to the structural material of the approach, the gutter member is liable to be cracked, and the appearance is bad and it does not look good. There was a problem. In addition, when a trough is provided inside the structural material by the above-mentioned conventional interior system, if water is directly passed inside the structural material, the structural material itself will be corroded and the durability will be poor, and the structural material will not be punctured. There is a problem that the strength of the structural material is weakened by opening the holes.

The object of the present invention is to solve the above-mentioned problems of the prior art, to allow the drainage device to be integrated with the approach body, and to prevent the strength of the structural material from being lowered, and at the same time, to improve the structural material itself. An object of the present invention is to provide a drainage device in an assembly building such as an approach, which is capable of preventing corrosion, has excellent durability, and is capable of eliminating deterioration in appearance.

[0005]

SUMMARY OF THE INVENTION In order to achieve the above object, the present invention provides a pair of left and right girder members provided on the left and right side edges of the roof and having eaves gutters, and a front and rear portion under the roof. In a prefabricated building such as an approach including a plurality of pillars arranged at required intervals and a roof supporting beam member attached to the upper end of each pillar to support the roof, , A connecting gutter member having a connecting gutter portion is placed in the longitudinal direction, and the left and right end portions of the roof supporting beam member and the connecting gutter member and the required portions of the left and right girder members are respectively connected via connecting members. Along with being connected, the eaves gutters of both left and right girder members are made to communicate with each other through the connection gutters of the above connection gutter members, and the left and right ends of the roof support beam and the connection gutter members are covered with caps. Vertical with a gutter along one side of the pillar A drainage device in an assembled building, such as an approach, is designed so that the rainwater in the connecting gutter part of the connecting gutter member can be drained by flowing down the inside of the vertical gutter part of the vertical gutter member along the pillar on the same side. It is a summary.

[0006] In the above description, the columns are usually arranged two to four in the front and rear at required intervals, although it depends on the length of the drainage device in the assembly building such as the approach.

[0007]

In the above, the connection gutter member having the connection gutter portion is placed on the roof supporting beam, and the eaves gutter portions of the left and right girder members of the roof are mutually connected via the connection gutter portion of the connection gutter member. It is in communication. Further, a down gutter member having a down gutter portion is attached along one side surface of the column.

Then, the rainwater that has fallen on the roof flows into the eaves gutters of the left and right girders, respectively, and the rainwater then moves from these eaves gutters to the connection gutters of the connection gutter members. Furthermore, the rainwater flows down through the water discharge hole provided at the required location on the side wall of one of the connecting gutter members, through the inside of the vertical gutter part of the vertical gutter member along the pillar on the same side, and is discharged to the outside from the lower end of the vertical gutter member. It can be done.

Therefore, according to the present invention, the drainage device in an assembled building such as an approach can be integrated with the main body of the assembled building composed of the roof supporting beam and the columns, thereby eliminating the appearance deterioration. The appearance is very clean, the appearance is good, and the design is good.

Rainwater flowing from the roof into the eaves gutters of the left and right girders is discharged to the outside through the connection gutter of the connection gutter member and the vertical gutter part of the vertical gutter member along the column on the same side. So, inside structural materials such as columns and roof support beams,
It has excellent durability because it can prevent corrosion of structural materials without passing water directly. Further, the trough does not crack with time.

Further, even if corrosion occurs in the connecting gutter member or the vertical gutter member, the drainage device can be repaired easily and inexpensively by replacing these members in the worst case.

Further, since water holes are not formed in the structural material itself such as the support columns and the roof supporting beam material, it is possible to prevent the structural material from being deteriorated in strength and have excellent durability.
