Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to an underground storage.

[0002]

[Prior art]

 Traditionally, underground storage has been constructed to secure storage spaces such as storage units and sheds in a limited land area.

That is, as shown in FIG. 2, the underground storage 1 has a box-shaped storage main body 2 consisting of a bottom wall 21, a peripheral wall 22 and a ceiling wall 23 made of resin concrete or the like and buried underground. Then, a rectangular opening 2a is formed as a doorway at one corner of the ceiling wall 23. The opening 2a of the storage case body 2 is located facing the opening 10a formed in the floor plate 10 of the house. A pair of L-shaped mounting brackets 3 are fixed to the inner wall surface 23a of the opening 2a of the storage case main body 2 near the peripheral wall 22 of the storage case main body 2. The stairs 4 are fixed and are leaned against the inner surface of the bottom wall 21.

Specifically, the stairs 4 includes a pair of columns 41, a plurality of treads 42 fixed to the columns 41 with a kick-up h1 and a tread w1 and a handrail fixed to the outer surface of one column 41. The support column 41 of the stairs 4 is connected and fixed to the mounting bracket 3 via a screw. Therefore, in the opening 2a of the storage case main body 2, the stairs 4 having a constant gradient are arranged from the inner wall surface 23a on one short side to the inner wall surface 23b on the other short side.

The above-mentioned floor board 10 is supported via the haul 11 and joists 12, and an opening / closing floor hatch 13 is provided in the opening 10a.

[0006]

[Problems to be Solved by the Invention] By the way, when the first step is going through the opening 10a formed in the floor board 10 in order to descend into the underground storage 1, the floor board 10 and the ceiling wall 23 of the storage body 2 are separated from each other. Considering the height, the uppermost tread 42 of the stairs 4 is arranged so as to be located in the opening 2a. As a result, the tread 42 narrows the area of the opening 2a, which makes it difficult for people to enter and exit and it is difficult to descend.

It is impossible to make the opening 2a larger than a certain size because the opening 2a becomes smaller in strength of the storage case body 2.

In addition, in order to make it easier to descend the stairs 4 in the above-described stairs 4, if the gradient determined by the ratio of the tread w1 and the lift h1 is set gently, the inner wall surface on the other short side of the opening 2a in the course of descending Since the head and the like collide with 23b, steep stairs must be used so that a person who goes down the stairs may not come into contact with the stairs, and there is a risk of stepping off.

The present invention has been made in view of the above problems, and provides an underground storage that can secure an entrance and exit opening of a sufficient size and can build stairs with a gentle slope. Is.

[0010]

[Means for Solving the Problems]

 The present invention embeds a box-shaped storage main body composed of a bottom wall, a peripheral wall and a ceiling wall in the ground so that a rectangular opening formed in one corner of the ceiling wall faces an opening formed in a floorboard of a house. In addition, the tread plate is fixed to the outer surface of the ceiling wall along which the inner wall surface on the short side close to the one peripheral wall of the opening in the main body of the storage is located. It is characterized in that a staircase having a tread plate fixed between a pair of side plates is installed between the tread plate fixed to the outer surface of the ceiling wall and the corresponding inner surface of the ceiling wall and the inner surface of the bottom wall.

[0011]

[Operation] A tread plate is fixed to the outer surface of the ceiling wall along which the inner wall surface on the short side close to the one peripheral wall of the opening of the storage main body is arranged, and further, the tread plate is lifted and the tread surface is provided with a plurality of tread plates based on the tread plate. The stairs, which are fixed to a pair of side plates, are installed between the inner surface of the ceiling wall and the inner surface of the bottom wall corresponding to the tread plate fixed to the outer surface of the ceiling wall.

[0012] As a result, when descending into the underground storage from the floor plate through the treads fixed to the outer surface of the ceiling wall and the treads of the stairs, the top tread of the stairs goes over the opening formed in the ceiling wall and the storage main body Since it can be located inside, it is possible to construct stairs with a gentle slope without narrowing the entrance / exit of the main body of the storage, and it is possible to descend safely with room.

[0013]

【Example】

 Hereinafter, embodiments of the present invention will be described with reference to the drawings.

FIG. 1 shows an underground storage 1 of the present invention. The underground storage 1 is made of resin concrete and has a box-like shape composed of a bottom wall 21, a peripheral wall 22 and a ceiling wall 23, as in the conventional case. The storage main body 2 is buried underground, and a rectangular opening 2a is formed at one corner of the ceiling wall 23, and the opening 2a faces the opening 10a formed on the floor plate 10 of the house. Is located in.

By the way, on the outer surface of the ceiling wall 23 of the storage main body 2, a tread plate 52A is fixed along the short side inner wall surface 23a of the opening 2a which is close to the one peripheral wall 22, and the tread plate 52A is also fixed. The stairs 5 are provided between the inner surface of the bottom wall 21 and the inner surface corresponding to the outer surface of the ceiling wall 23 to which 52A is fixed. The stairs 5 are configured by fixing a plurality of treads 52 between a pair of side plates 51, 51 with a foot h and a tread w on the outer surface of the ceiling wall 23 as a reference. There is.

Therefore, in order to descend from the house side into the underground storage 1, first, the floor hatch 13 is lifted to form the opening 10a, and then fixed to the outer surface of the ceiling wall 23 of the storage main body 2 through the opening 10a. The first step may be placed on the stepped plate 52A, and thereafter, the stairs 5 may be stepped down via the plurality of treads 52 fixed at the rise h and the tread w.

In this case, since the uppermost step plate 52 in the stairs 5 is located inside the storage case main body 2 beyond the opening 2a, the opening 2a can be lowered without a narrowing. Further, since the uppermost tread 52 is located inside the storage case body 2 beyond the opening 2a, the position of the uppermost tread 52 is moved to a lower position than in the conventional case. The slope of the stairs 5 determined by w can be gently formed, and the stairs 5 can be safely descended.

[0018]

[Effect of device]

 As described above, according to the present invention, the box-shaped storage body including the bottom wall, the peripheral wall, and the ceiling wall has a rectangular opening formed in one corner of the ceiling wall facing the opening formed in the floorboard of the house. It is buried underground as described above, and the tread plate is fixed to the outer surface of the ceiling wall along which the inner wall surface on the short side close to the one peripheral wall of the opening of the storage main body extends, and the rise and tread surfaces are set with this tread plate as a reference. In addition, the stairs with a plurality of treads fixed between a pair of side plates were installed between the inner surface of the ceiling wall and the inner surface of the bottom wall corresponding to the treads fixed to the outer surface of the ceiling wall. When going down to the underground storage via the treads fixed to the outer surface of the ceiling wall and the treads of the stairs, the top tread of the stairs can be positioned inside the storage main body beyond the opening formed in the ceiling wall. Narrowing the entrance and exit of the storage body DOO no, also, it is possible to construction a gentle staircase slope, with a margin, and it is possible to safely descend.
