and a water cutting section 37 that is bent and connected to the lower end surface, and the water cutting section 37 is connected to the groove 15.
The vertical fixing piece 36 can be fixed to the vertical inner wall of the groove 15 by making it contact the waterproof sheet 30 on the lower inner wall of the groove 15 and by making its tip sufficiently protrude outside the outer walls 14, 14. . Once the fixing of the water cutout fitting 33 is completed, the heads of the screws 34, etc. are covered with caulking material 38, and further, from the outside, the space between the water cutout pieces 37 and the upper inner wall of the groove 15 is covered. It is preferable to fill with a sealing material 39 such as urethane, and on the other hand, it is preferable to apply the protective mortar 31 using the water cutting parting fitting 33 as a ruler. Note that the above-mentioned waterproofing treatment in the present invention is not limited to the embodiments, and for example, the outer wall body 14,
The lower part of the outer wall surface, the lower end surface, and the lower part of the inner wall surface of 14 may be impregnated with a waterproofing agent, and when the waterproofing agent is impregnated, for example, without attaching the waterproof sheet 30 to the lower end surface of the outer wall bodies 14, 14. You can leave it there.

Next, the manner in which a semi-basement is formed by the above-mentioned semi-basement units will be explained. In forming a semi-basement, first, as shown in FIGS. 5 and 6, units 1, 1, ...... is installed adjacent to the cloth foundation 4 previously provided in the root cutting excavation part (not shown) using a hanging jig 50. As shown in FIG. 12, it is preferable that the cloth foundation 4 is waterproofed at least on its upper end surface and outer surface.
This is done by pasting 0. Of course, this does not prevent the waterproofing of the inner surface of the cloth foundation 4, and in fact, as shown in FIG. , a moisture-proof sheet 41 made of a polyethylene sheet is attached. When installing the units 1, 1 of the present invention, which are also waterproofed, on the cloth foundation 4 which has been subjected to waterproof treatment, the lower end surfaces of the outer walls 14, 14, . . . As shown in FIGS. 10 and 12, a fixed-shaped gasket 60 is interposed between the upper end surface of the fixed-shaped gasket 60 and a joint 6 is formed outside the fixed-shaped gasket 60. The size of the standard gasket 60 is the same as that of the outer wall 1.
It is preferable to use a material that can seal between the lower end surfaces of 4 and 14 and the upper end surface of the cloth foundation 4. Incidentally, the load of the units 1, 1 is mainly supported by the hard elastic body 52 between the steel frame 10 and the cloth foundation 4, and by the anchor bolts (not shown) passing through the inside thereof. Moreover, when the above-mentioned unit 1 without the floor panel 11 is installed on the cloth foundation 4, the earthen floor concrete part 51 is formed higher than that shown in FIG. It is best to form the floor by painting it.

After the adjacent installation work of the units 1, 1, .
Waterproof joint treatment is performed on the waterproof joints 7 between the outer walls 14, 14 of the adjacent units 1, 1, as shown in FIGS. 8 and 9.

The above-mentioned waterproof joint treatment on the outside of the regular gasket 60 may be carried out by filling the joint portion 6 with a sealant 61 such as urethane foam and the regular gasket 60 as a back-up material, as shown in FIG. 12, and is preferably performed. As shown in the figure, an additional waterproof sheet 62 may be attached between the underground outer surface of the waterproof sheet 30 and the outer surface of the waterproof sheet 40. In addition, in FIG. 12, reference numerals 63, 63 are caulking materials for sealing the upper and lower edges of the waterproof sheet 62.

Furthermore, the waterproof joint treatment of the joint 7 between the units 1 and 1 can be carried out in the same manner as the waterproof joint treatment of the unit 1 itself described above in FIG. 3, and as shown in detail in FIG. After inserting the back-up material 70 into the joint and filling the outside of the sealing material 71, the outside of the joint 7 is closed with an insulating tape 72, and the outer walls 14, 14 are covered from above the tape 72. This can be done by attaching an additional waterproof sheet 73 on top of the waterproof sheet and applying protective mortar 74 to the outside thereof.
In addition, in order to facilitate the application of additional waterproof sheet 73 and the application of protective mortar 74, the application of protective mortar 31 in the above-mentioned waterproofing of the unit 1 itself covers the joints 2 and the outer wall. Preferably, it is not carried out at the side ends of the bodies 14,14.

After performing waterproof joint treatment in this way, a semi-basement with a waterproof structure can be formed by backfilling the excavated part of the roots. However, by performing the following work before backfilling, it is possible to The structure can be made complete, and the appearance of the semi-basement can be made beautiful. That is, FIGS. 10 and 12
As shown in the figure, if a protective material 80 such as a polypropylene hollow sheet is provided over the entire underground outer surface of the outer wall body 14 and the outer surface of the cloth foundation 4, all of the above-mentioned waterproofing sections and waterproof joint processing sections can be protected. Waterproof effect can be protected. Note that the protective material 80 is the first
As shown in Figure 0, it is preferable to arrange the upper edge of the protective mortar 31 on the surface of the outer wall 14 so as to coincide with the lower edge of the protective mortar 31, and after the arrangement is completed, between that surface and the surface of the protective mortar 31. It is a good idea to apply waterproof sealing tape. Immediately before the backfilling of the excavated root section is completed, it is preferable to apply a regular mortar 81 to the surface of the protective mortar 31 using a brush finish or the like, as shown in FIGS. 7, 10, and 11. By doing this, as shown in FIG. 7, the outer surface of the semi-basement which is not buried underground can be given the appearance of a cloth foundation. Normally, the mortar 81 has a protective mortar 31 as a base material, and the waterproof sheet 30 to which the protective mortar 31 is applied is not firmly attached to the outer wall 14 due to the water-cutting fittings 33 and adhesive.
