Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to the improvement of synthetic resin or metal basements.

Recently, in order to increase the storage capacity of conventional underfloor storages that utilize the underfloor space of kitchens, living rooms, etc., various types of basements have been proposed that are buried from under the floor to below the ground.

This basement is large enough that a person can open the floor cover on the floor of the house and climb into the basement using a ladder or the like to store and take out items, and the weight of the stored items is also large. Therefore, it must be fixed on a foundation installed underground.

Conventionally, the tip of an anchor bolt attached to the foundation was projected onto the floor of the basement and then tightened and fixed with a nut.

However, in the above case, the protruding part is formed on the floor surface, which not only gets in the way when placing stored items on the floor, but also makes it difficult to store and take out items. There was also the risk of tripping, which was not desirable.

The object of the invention is to provide a basement that does not have the above-mentioned disadvantages.

The present invention relates to a basement made of synthetic resin or metal, in which a recess is provided in the floor and an anchor bolt is fixed at the bottom of the recess.

There is no limit to the shape of the recess provided in the floor surface in the present invention, but the recess is usually provided integrally with the floor member of a basement, so it is preferable to have a simple shape such as a groove or hole. .

FIG. 1 is a sectional view of a basement partially buried under the ground as an embodiment of the present invention, and FIG. 2 is a partially cutaway plan view of the floor of the basement of FIG.

As shown in the figure, two grooves 2 are provided on the floor of the basement 1 with an interval between them.
An anchor bolt 5 protruding from the bottom surface is tightened and fixed with a nut 6 via a metal fitting 4. Reference numeral 14 is a foundation made of concrete or the like to which the anchor bolt 5 is attached, and 8 is a lid covering the groove 2, which is usually mounted on the groove 2 so as to have the same plane as the floor surface.
A pit 7 is formed on the floor of the basement 1 along the inner wall surface, and is connected to the groove 2 in the middle. Reference numeral 9 denotes an upper opening of the basement 1, which is usually covered with a floor cover 12a provided on the building floor 12.

FIG. 3 is a plan view of another floor surface different from FIG. 2, and FIG. 4 is an enlarged sectional view of the hole shown in FIG. 3. In this case, four holes 3 are provided at intervals on the floor of the basement 1, and within the holes 3, anchor bolts 5 protruding from the bottom of the holes 3 are connected to the metal fittings 4a and the seals 1.
1. It is tightened and fixed by the nut 6 via the holding nut 10. In the case of the hole 3, the area of the opening is smaller than that of the groove 4, so the cover does not necessarily have to be provided, but it may be used if necessary. 7
are the same pits as above, and are connected to the respective holes 3. Note that the configuration of the tightening member shown in FIG. 4 can also be applied to the groove 2.

According to the present invention, recesses such as grooves and holes are formed in the floor of the basement, and the anchor bolts are fixed at the bottom of the recess.Therefore, there is no protruding part on the floor, so the floor is free when storing items. Not only can it be used effectively, but it also makes it easier to store and take out items. Furthermore, since the recess is connected to the pit, it can be used as a collection area for condensation and leakage water that tends to occur in the basement.
