2. Description of the Related Art When installing a waterproof pan that constitutes a floor of a unit bathroom or the like, it is necessary to adjust the height thereof, and as a method therefor, the lower surface of the conventional waterproof pan is used. A large number of adjustment bolts are provided on the side facing downward, and these adjustment bolts are rotated.

However, in this case, a large number of bolts must be adjusted by lifting the waterproof pan and extending the hands downward from the peripheral edge, which is very difficult for the work.

On the other hand, the height of the adjusting bolts is adjusted only at the four corners of the waterproof pan, these are grounded to the installation surface, the other bolts are left floating, and the bolts in the floating state are As shown in FIG. 4, the uncured mortar 102 contained inside the tubular member 100.
It is also practiced to embed it and harden the mortar 102 to support it.

However, even in the case of this method, there is a problem that it takes a lot of time and labor such as installation of a large number of cylindrical members 100, filling of the mortar 102, and curing for hardening the mortar 102.

[0006]

The invention of the present application has been made to solve such a problem. Thus, in the invention of the present application, the waterproof pan is provided with the adjusting bolt projecting downward and the through hole is provided in the waterproof pan at the upper part of the adjusting bolt, and the waterproof pan is placed on the installation surface. Adjusting the height of the adjusting bolt from the through hole,
After that, the through hole is closed (claim 1).

Another invention of the present application is characterized in that the through hole is filled with an elastic putty having rubber-like elasticity after curing in an uncured state to close the through hole (claim 2).

Still another invention of the present application is characterized in that a part of the through hole is filled with a backup member, and a filling material is filled on the backup member to close the through hole. 3).

Still another aspect of the present invention is characterized in that the adjusting bolt is provided at a portion closer to the center of the waterproof pan than the rising portion of the peripheral edge of the waterproof pan (claim 4).

[0010]

As described above, according to the first aspect of the invention, the waterproof pan is provided with a through hole corresponding to the adjusting bolt, and the adjusting bolt is adjusted using this hole.

According to this method, it is not necessary to lift the waterproof pan or to insert the hand from the peripheral edge to the lower side to perform the work in an unreasonable posture, and to adjust each adjusting bolt from the upper side of the waterproof pan. You can Therefore, the height of the waterproof pan can be easily adjusted, and the installation work of the waterproof pan can be easily performed in a short time.

According to the second aspect of the present invention, the through-hole of the waterproof pan is closed by using the elastic putty, which exhibits rubber-like elasticity after the curing reaction, so that the following effects can be obtained.

Generally, the waterproof pan is made of a plastic material such as FRP. Therefore, a resin material is generally considered as a filling material for closing the through hole, but when such a resin material is filled in the through hole, shrinkage occurs due to the curing reaction of the resin material, and the filling is performed based on this shrinkage. A crack occurs between the material and the inner surface of the through hole or in the filler itself. When such a crack is generated, water may leak from the crack.

However, since the elastic putty of the present invention has rubber-like elasticity even after the curing reaction, it does not cause such cracks, and therefore does not cause the problem of water leakage due to the cracks.

The elastic putty also prevents the occurrence of cracks due to its elasticity even when a person is placed on the waterproof pan and the waterproof pan bends due to its load.

According to the third aspect of the present invention, a part of the through hole is filled with a backup material such as foam material, and a filling material such as elastic putty is filled on the backup material to close the through hole. The advantage is that less filler is required and the filling operation of the filler is simplified.

According to a fourth aspect of the present invention, adjusting bolts are provided closer to the center of the waterproof pan than the rising portion of the peripheral edge of the waterproof pan, and the height is adjusted by these adjusting bolts.

When installing the waterproof pan, it becomes more difficult to operate the adjusting bolt as the position of the bolt becomes farther from the periphery of the waterproof pan. However, when the waterproof pan is provided with a through hole and the adjustment bolt is operated through the through hole, the operation can be easily performed regardless of the position of the bolt. That is, the present invention is particularly effective when the adjusting bolt is located closer to the center of the waterproof pan than the peripheral edge of the waterproof pan.
