Core materials 10 to 1 framed in these rectangular shapes
The plywoods 20 and 21 of the same shape as the face material are attached to both side surfaces of the core member 4 so that the upper and lower ends of the core materials 10 to 14 and the both side edges are aligned with each other.

As a result, the core materials 10 to 14 and the plywood 2
Space parts 30 and 31 partitioned by 0 and 21 are formed inside.

In the space portion 30, a square pipe 40 as a downspout set to be longer than the core members 10 to 12 is provided.
The core material 1 is vertically arranged inside and the upper and lower ends thereof are upper and lower.
It is attached so as to penetrate through 3, 14 and open at the top and bottom.

Specifically, the square pipe 40 is a tubular body having a rectangular cross section, which is molded from synthetic resin or the like, and the orthogonal surface portions 4 are formed.
The corners 1 and 42 are attached so as to coincide with the corners between the inner surface of the face material 20 and the side surface of the central core material 11. In this way, by aligning the corners of the face portions 41 and 42 with the corners of the face material 20 and the core material 11, the square pipe 40 is positioned in the plane direction.

Further, the projecting lengths of the opening end portions 43, 44 projecting vertically from the upper and lower core members 13, 14 are as shown in FIGS.
As shown in, the thickness of the floor panels 600 and 610 is set to be substantially equal.

Next, the drainage structure of the snowless roof according to this embodiment, to which the gutter-embedded wall panel is applied, will be described with reference to FIGS.
It will be described with reference to FIG.

In constructing a house with a snow-free roof in FIG. 1, when the foundation 500 is first attached, it corresponds to the square pipe opening end 44 of the gutter built-in wall panel 1 (110) which is erected on the first floor. A notch 71 that opens upward is formed at a location of the base 500.

Then, as also shown in FIG. 4, a funnel body 60 into which the lower opening end portion 44 can be fitted is attached upward in the notch 70. Reference numeral 61 is a pipe leading to a drainage basin (not shown).

Then, the floor panel 600 of the first floor is laid on the foundation 500. At this time, the core members 601 and 601 of the floor panels 600 and 600 laid at the position of the funnel body 60 are placed. Is provided with a cutout hole 71 that escapes from the funnel body 60.

Next, as shown in FIG. 1, the gutter built-in wall panel 110 is erected on the laid floor panel 600 together with other wall panels.

At this time, as shown in FIG. 4, the square pipe 40
When the lower opening end portion 44 of the above is fitted inside the funnel body 60,
Since the square pipe 40 and the funnel body 60 are connected and the lower surface of the wall panel 110 with a built-in gutter abuts on the upper surface of the floor panel 600, in this state, the wall panel 110 with a built-in gutter is tightened through the tightening operation hole 90. If the floor panel 600 is bolted and fixed, the gutter built-in wall panel 110 is erected and fixed on the floor panel 600.

The floor panel 610 on the second floor is located above the gutter built-in wall panel 110 and other wall panels erected in this way.
Is laid. Also at this time, as shown in FIG. 5, the floor panel 6 laid on the upper side of the gutter built-in wall panel 110.
Cutout holes 71 that escape from the upper open end portion 43 of the square pipe 40 are provided in the core members 611 and 611 of the reference numerals 10 and 610.

Then, as shown in FIG. 1, a gutter-incorporated wall panel 120 on the second floor is erected on the laid floor panel 610 together with other wall panels.

At this time, as shown in FIG. 5, the lower opening end 44 of the square pipe 40 arranged in the gutter built-in wall panel 120 on the second floor is arranged in the gutter built-in wall panel 110 on the first floor. When it is fitted inside the upper opening 43 of the above, the square pipes 40, 40 on the first floor and the second floor are connected, and the lower surface of the gutter built-in wall panel 120 on the second floor contacts the upper surface of the floor panel 610 on the second floor. So, in this state, the gutter built-in wall panel 12
0 is bolted and fixed on the floor panel 610 through the tightening operation hole 90, the gutter built-in wall panel 120 becomes the floor panel 61.
It is erected and fixed on 0.

Finally, a snow-free roof (not shown) is formed,
The square pipe 40 of the gutter built-in wall panel 120 on the second floor is connected to the gutter 300 arranged below the gap in the central valley portion.

As shown in FIG. 6, the horizontal gutter 300 and the square pipe 40 are connected to each other by connecting the lower end 80 of the connecting pipe 81 whose upper end is attached to the horizontal gutter 300 to the upper opening end portion 43 of the square pipe 40.
It is done by fitting it inside.

That is, the upper open end 4 of the square pipe 40.
The position of 3 is displaced from the position directly below the gutter 300, and the connection pipe 81 is also formed correspondingly to the position of the upper and lower ends, and the connection pipe 81 is used to connect the gutter 300 and the square pipe. 40 is connected.

In this way, the drainage structure from the gutter 300 to the funnel body 60 below is completed, so that the snowmelt and rainwater that have reached the inside of the gutter from the gap of the snow-free roof will not enter the corner inside the gutter built-in wall panel 1. It reaches the funnel body 60 via the pipe 40 and is discharged to the sewer via the hose 61 of the funnel body 60.

At this time, the sound of snow melt down flowing through the square pipe 40 is absorbed by the heat insulating material 50 inside the gutter built-in wall panel 1, so that the resident does not hear the sound of falling snow melt. .

As described above, according to the drainage structure of the snowless roof of this embodiment, the plumbing work of the wall panel 1 with a built-in gutter and the plumbing work of the square pipes 40 are automatically performed at the same time to construct a house. Since the snowfall roof is assembled and the drainage structure of the snowfall roof is completed at the same time, it is not necessary to attach pipes for temporary drainage as in the conventional example described above.
It is possible to speed up the construction site work and save labor.

Further, since the square pipe 40 as a downspout in the wall panel is built in, it is not necessary to provide a special space portion for piping the downspout unlike the conventional example.

In this embodiment, the square pipe 40 is used as the vertical gutter built in the wall panel, but it goes without saying that a round pipe may be used.

[0047]

As described above, in the method for constructing the drainage structure for a snowless roof according to the present invention, since a house is constructed and the snowless roof is assembled, the plumbing pipe is completed at the same time. It does not require on-site work for mounting and can save labor on construction site work.

Further, since the work of attaching and detaching the temporary pipe is omitted, there is an excellent effect that the construction work can be speeded up.
