打込み乾燥せしめる。First, a rod-shaped plug member 4 formed by twisting a bar-shaped member, such as newspaper, is fitted into the upper end of the drainage pipe 3 with its tip properly projected so that the concrete 2 does not flow into the drainage pipe 3. To do so. Next, as shown in FIG. 9, concrete 2 is poured into the pool-like space formed by the mold 1 and dried.

水平保持が困難であるという不具合な点があった。Further, since the drainage structure of the building is constructed after the drain installation space 5 is formed in the concrete 2 as described above, it takes a lot of time and labor and is uneconomical. Although mortar is injected into the gap between the drain installation space 5 and the drain to solidify it, the solidified mortar must be modified in shape and it is difficult to hold the drain horizontally.

Next, as shown in FIG. 1, the concrete 2 is poured into the pool-shaped space assembled in the mold 1 so that the upper surface of the concrete 2 is located below the upper surface of the mold member 6 and dried and solidified. After that, the mold member 6 is deformed to remove it from the concrete 2, and a recess 10 having a desired shape is formed in the concrete 2 as shown in FIG. At this time, since the mold member 6 is made of resin, it can be easily removed from the concrete 2 by breaking the shape of the mold member 6 with bare hands without using a special tool, that is,
As shown in FIG. 3, the concave portion 10 having a shape corresponding to the mold member 6 can be easily formed in the concrete 2, and the surface of the mold member 6 is smooth (no unevenness). The surface becomes smooth, and it is convenient that the surface of the concrete 2 does not need to be subjected to post-processing such as polishing. The mold member 6 may be easily peeled (or pulled out) from the concrete 2 by attaching a release agent, oil paper, or the like to the surface where the mold member 6 and the concrete 2 contact each other. The outer diameter of the disk 8 may be increased as the distance from the cylindrical body 7 is increased, and the outer diameter of the cylindrical body 7 may be increased as the disk 8 is approached to facilitate peeling.

That is, in the drain 11, as shown in FIGS. 4 and 5, a cylindrical wall (may be a polygonal cylindrical wall) 14 is concentric with the drain pipe 12 on the lower surface of the large diameter portion 13 which is continuous with the drain pipe 12. The outer peripheral surface of the cylindrical wall 14 and the large diameter portion 13 are provided.

They are provided at equal intervals. Further, reference numeral 19 in the drawing denotes a seat of a plurality of protrusions (three in the drawing) provided on the upper surface of the large diameter portion 13 of the drain 11 as shown in FIGS.

っかりと固定することができる。As shown in FIG. 4, the drain 11 configured as described above is fitted with the lower end of the drain pipe portion 12 on the upper end of the drain pipe 3 and the lower end of the cylindrical wall 14 stands on the bottom surface of the recess 10 of the concrete 2. Installed and placed in a supported state,
Next, the mortar 25 is poured into a ring-shaped space formed by the inner peripheral surface and the bottom surface of the recess 10 and the outer peripheral surface of the cylindrical wall 14 to be solidified. At this time, the outer diameter of the large-diameter portion 13 of the drain 11 is substantially the same as the inner diameter of the concave portion 10, and the outer circumference of the large-diameter portion 13 and the concave portion 10 are the same.
It is difficult to inject the mortar 25 into the recess 10 from between the inner periphery of the recess 10 and the mortar 25, but the protrusion 9 of the mold member 6 causes the recess 10 to move.
Since the mortar 25 can be injected by using the passage portion 10a extended on the outer peripheral surface of the mortar 25, it is not necessary to use a dedicated device for injecting the mortar 25 or to newly provide an injection passage for the mortar 25. The cylindrical wall 14 allows the mortar 25 to move to the drain pipe 3 and the concrete 2 as well.
There is no need to perform post-processing because it does not flow into the gap between the mortar and the mortar by fixing the fixing plate 15 and the fixing rod 16 of the drain 11 while keeping the drain 11 horizontal by the cylindrical wall 14. Since 25 is poured and solidified, the drain 11 can be firmly fixed to the concrete 2 in a stable state.

The waterproof sheet 27 is adhesively fixed and covered over the upper surface of 6 and the concrete 2, and then the lid 21 is fixed to the protruding seat 19 of the large diameter portion 13 of the drain 11 by the fixing screw 24. Therefore, since the packing sheet 26 and the waterproof sheet 27 have a double waterproof structure from the midway portion of the upper surface of the large diameter portion 13 of the drain 11 to the upper surface of the concrete 2, the permeation of the drainage into the mortar 25 and the concrete 2 is prevented. This can be reliably prevented, and since the drain 11 is made of aluminum alloy or resin, corrosion such as rust does not occur in the drain 11, and as a result, the useful life of the building can be significantly extended.

At that time, the flow dividing wall 17 can prevent swirling of the inflowing drainage, and the drainage can smoothly flow out.

2 is passed through the cylindrical wall 14, the lower end of which is fitted to the upper end of the drainage pipe 3 and horizontally supported on the upper end of the cylindrical wall 14 and is placed in the recess 10, and the mortar 25 is poured into the recess 10 and solidified. . After that, the packing sheet 26 and the waterproof sheet 27 are covered in the same manner as in the above-mentioned embodiment, and the lid 21 is attached to the drain 11.

And the mortar 25 is injected through the gap 28. Therefore, it is not necessary to provide the protruding portion 9 on the disk 8 of the mold member 6, and the surface of the mortar 25 exposed from the gap portion 28 is horizontal, but the concrete 2 with the same inclination as the upper surface of the large diameter portion 13 of the drain 11 is used. As shown in FIG. 7, a continuous inclined surface is formed from the large diameter portion 13 of the drain 11 to the edge of the recess 10 of the concrete 2 by only partially applying the mortar 25 so as to be continuously connected to the edge of the recess 10. It can be easily formed to facilitate drainage inflow.

を発揮する。According to the method for constructing a drainage structure of a building of the present invention, a drainage structure for a building is constructed by interposing a cylindrical wall between a recess formed in concrete and a drain installed in the recess. Therefore, it is possible to prevent the mortar injected into the recess from flowing out, and it is economical without the need for post-processing associated with the mortar outflow.In addition, by pouring the mortar and solidifying it, the drain can be kept horizontal and firmly attached to the concrete. It has an excellent effect that it can be fixed with a convenient position.
