Description

[Detailed Description of the Invention] [Technical Field] The present invention relates to a ventilation structure in the attic below the floor of a multi-story house such as a two-story building, and specifically relates to a technique for improving construction efficiency.

[Background technology]

Conventionally, as a ventilation structure for discharging hot air rising from the attic to the outside, the communication path that communicates with the attic is covered with a drainage board over the entire length of the corner part, and this drainage board is bent to close the bent part. A communication hole that communicates with the communication path is formed in this bent part, and a corner cover is provided on the upper surface of the draining plate over the entire length of the corner part, and the corner cover is lowered from the corner part toward the eaves. Ventilation vents open to the outdoors are formed at certain points, and the structure is such that hot air from the ceiling is discharged outside through the vents through the communication holes. However, in such a structure, the drain plate and the corner cover are installed along the entire length of the corner, and since they are long pieces, the workability is poor, and furthermore, the drain plate and corner cover are installed along the entire length of the corner. There were problems such as the seals that ensure watertightness were also cumbersome.

[Purpose of invention]

The present invention was devised in view of these problems, and its purpose is to provide a ventilation structure for the attic below the floor of a multi-story house that is easy to construct.

[Disclosure of invention]

The present invention covers a communication passage 3 communicating with the attic 10 on the lower floor over a fixed distance in the corner length direction at the corner formed by the roof 1 on the lower floor and the outer wall 2 on the upper floor, and also covers the communication passage 3 communicating with the communication passage 3 in the corner length direction. A ventilation unit 6 is constructed by connecting a draining plate 4 having holes 5 and a corner cover 9 having a ventilation opening 11 which is arranged on the outside of the draining plate 4 and is approximately the same length as the draining plate 4 and is open to the outdoors. A connecting part 7 is formed at one end of the ventilation unit 6, a connected part 8 is formed at the other end, and the connecting part 7 and the connected part 8 are connected to connect the ventilation unit 6 group to the corner part. This is a ventilation structure in the attic below the floor of a multi-story house constructed over the entire length of the building, and by configuring it in this way,
We were able to achieve the above objectives. In other words, by using the ventilation unit 6 that connects the draining plate 4 and the corner cover 9, the connection part 7 and the connected part 8 can be connected to perform construction of the corner part. It is designed so that it can be done easily and easily.

Embodiments of the present invention will be described in detail below based on the drawings.

A communication path 3 that communicates with the attic 10 on the lower floor at the corner formed by the roof 1 on the lower floor and the outer wall 2 on the upper floor
is formed over the entire length of the corner portion. A draining plate 4 which covers this corner portion over a certain distance and has a communication hole 5 communicating with the communication path 3 is formed by bending it into an approximately L shape. The communication hole 5 is approximately circular, and a hat-shaped rain shield 12 is installed in the circular communication hole 5.
is installed to prevent rainwater from entering the communication hole 5. A corner cover 9 is formed by bending a corner cover 9 which is disposed outside the draining plate 4 and has a ventilation opening 11 that is approximately the same length as the draining plate 4 and is open to the outdoors. be. A drainage port 22 is formed at the lower end of the corner cover 9 so that rainwater that has entered through the ventilation port 11 can be drained. The ventilation unit 6 is constructed by connecting the draining plate 4 and the corner cover 9 with rivets or the like. In this case, the corner cover 9 is supported with respect to the draining plate 4 by a narrow metal fitting 13 via a heat insulating material 23 to prevent its deformation. As shown in FIG. 3, the ventilation unit 6 has a corner cover 9 with one end protruding beyond the drain plate 4 to form a connecting portion 7. The other end of the corner cover 9 is formed as a connected portion 8 by folding back the folded piece 4 outward. By overlapping and connecting the connecting portion 7 and the connected portion 8 as shown in FIG. 4, the connection can be made while maintaining watertightness. Further, one end of the draining plate 4 extends laterally beyond the connected portion 8, and this extended portion is folded back outward to form a connecting side 15. And draining board 4
The other end is a connected side 16 that is overlapped on the fold 17 of the connecting side 15. Therefore, six groups of ventilation units are constructed along the entire length of the corner part, and a communication passage 3 communicating with the attic 10 is created at the corner between the roof 1 on the lower floor and the outer wall 2 on the upper floor, along the entire length of the corner part. ventilation unit 6
It is covered with. The specific construction structure is as follows. Rafters 18 are installed at intervals in the corner length direction on beams (not shown) extending over the entire length of the corner part, and a roof base material 19 is pasted between these rafters 18, so that the top part of the roof base material 19 is A communication path 3 communicates with the attic 10. A roof base material 19 is covered with flat tiles 20, and a ventilation unit 6 is constructed by placing a drainage board 4 on these flat tiles 20 via a ridge 21.

[Effect of idea]

In summary, the present invention forms a connection part at one end of the ventilation unit, forms a connected part at the other end, connects the connection part and the connected part, and connects the ventilation unit group in the length direction of the corner part. Since the construction is carried out along the entire length, the ventilation unit that connects the draining plate and the corner cover can be used to connect the connecting part and the connected part to perform the construction of the corner part. It has the advantage of being easy to construct.
