Description

DETAILED DESCRIPTION OF THE INVENTION [Technical Field] The present invention relates to a semi-underground storage shed whose lower part is buried underground.

[Background technology]

In recent years, so-called semi-underground storage has been developed, in which the lower part of a large box is buried underground and the upper part is opened to the floor so that the user can enter and exit the box through the opening in the floor. However, since the semi-underground storage is large, attempts are made to make effective use of the interior by attaching a shelf support frame inside and placing shelves on it, but as shown in Figure 1, the shelf support frame 18 is Since it was attached to the body 9 with bolts 19 and nuts 20, there was a problem that water could enter the interior through the through hole for inserting the bolts 19. As another conventional example, as shown in FIG. 2, a step 21 is provided on the inner circumference of the box 9, and a shelf support frame 18 is placed on the step 21, thereby eliminating the need for bolts and nuts. There is a type to which the shelf support frame 18 is attached, but since the lower part of the box body 9 is buried in the soil, when earth pressure Wo is applied, the shelf support frame 18 tries to come out from the stepped part 21 with a force W ₁ This causes the shelf holder frame 18 to come off, and if it comes off like this, the shelf holder frame 18 cannot be expected to have a reinforcing effect on the box 9.

[Purpose of the invention]

The present invention aims to solve the above-mentioned conventional problems.

[Disclosure of the invention]

The semi-underground storage of the present invention is provided with a lower part 2 and an upper part 3 at the center and upper end in the vertical direction of the inner peripheral part of the lower container body 1 which is open at the top.
The lower shelf receiving frame 4 placed on the upper shelf part 3 and the upper shelf receiving frame 8 placed on the upper part 3 are connected by a column 5, and a cylindrical structure having a lower part and an upper part opened at the upper opening of the lower container body 1 is formed. The lower opening of the upper body 6 is connected, and the lower horizontal piece 7 provided at the lower opening of the upper body 6 is positioned above the upper shelf receiving frame 4. This achieves the above-mentioned object of the present invention.

The present invention will be explained in detail below with reference to Examples. A box body 9 made of synthetic resin such as FRP consists of a lower container body 1 with an open upper part and a cylindrical upper body 6 with open upper and lower parts.
It is formed by combining. The lower container body 1 is provided with a lower part 2 and an upper part 3 at the vertical center and upper end of the inner circumferential part, respectively, a lower shelf receiving frame 4 is placed on the lower part 2, and an upper part 3 An upper shelf receiving frame 8 is placed thereon, and the lower shelf receiving frame 4 and the upper shelf receiving frame 8 are connected by a column 5. The lower opening of the upper body 6 is connected to the upper opening of the lower container body 1. Here, the flange 10 of the lower container body 1
and the flange 11 of the upper body 6 are joined together to secure the lower container body 1 and the upper body 6 to form the box body 9. In this case, the lower horizontal piece at the base of the flange 11 of the upper body 6 7 is located above the upper shelf receiving frame 8 to prevent the upper shelf receiving frame 8 from floating upward. In the figure, 12 is a spacer. In the box body 9 having the above-mentioned structure, approximately the lower half is buried in the ground 13, and the upper opening 14 and the opening 16 provided in the floor 15 are buried in the ground 13.
A lid (not shown) is removably covered over the opening 16 of the floor 15, and a person can enter and exit the box body 9 by removing the lid. be. Note that the box body 9 has a height that allows a person to stand if he or she enters the interior. Further, a shelf 22 is placed on the lower shelf receiving frame 4 and the upper shelf receiving frame 8.

〔Effect of the invention〕

In the present invention, as described above, a lower stage part and an upper stage part are provided at the vertical center part and the upper end part of the inner peripheral part of the lower container body, respectively, and the lower shelf receiving frame is placed on the lower stage part. , Since the upper shelf support frame is placed on the upper part, a bolt insertion hole is provided to penetrate the bolt, as in the conventional case.
It does not need to be attached with nuts, and there is no risk of water intruding from the attachment parts of the lower shelf holder frame and upper shelf holder frame, and the lower shelf holder frame placed on the lower tier and the upper shelf placed on the upper tier. The receiving frame is connected with a column, the lower opening of the cylindrical upper body with openings at the bottom and the upper part is connected to the upper opening of the lower container body, and the lower side provided in the lower opening of the upper body is connected to the upper opening of the lower container body. Since the piece is placed on top of the upper shelf support frame, the lower shelf support frame and the upper shelf support frame will not float upwards even when earth pressure is high, increasing the reinforcing effect and making it strong against earth pressure. It can provide semi-underground storage.
