Description

[Detailed Description of the Invention] [Technical Field] The present invention relates to an improvement in the fixing structure of an underfloor storage.

[Background technology]

Conventionally, when installing an underfloor storage, underfloor storage box 1
1st on the mounting base 5 of foundation concrete etc.
Since it was only mounted as shown in the figure, if water flooded under the floor during a flood, the underfloor storage box 1 would float up due to buoyancy, causing damage to the floorboard 8.

[Purpose of invention]

This invention eliminates the above-mentioned conventional drawbacks,
This is intended to securely and firmly fix the underfloor storage box.

[Disclosure of invention]

In the present invention, as shown in FIG. 2, an underfloor storage box 1 is attached to a mounting base 5 made of foundation concrete or the like using an L-shaped angle 6. In this case, as shown in FIG. 3, a recess 3 is provided at the lower end of the circumferential wall 2 of the underfloor storage box 1, and the plate 4 is secured to the recess 3, and the anchor bolt is secured to the recess 3. The upright piece of the L-shaped angle 6 attached to the mounting base 5 at 9 and the plate 4 are fastened with bolts 7, and both clamp the peripheral side wall 2 of the underfloor storage box 1. 10
is Natsuto. Here, it is desirable that the lower edge of the plate 4 be in close contact with the bottom surface of the underfloor storage box 1. Further, the recess 3 may be substantially aligned with the plate 4 as shown in FIG. 4, or may be groove-shaped as shown in FIG. Furthermore, when attaching the L-shaped angle 6, as shown in FIG.
The mounting position in the direction and the Y direction may be freely adjustable.

[Effect of idea]

In the present invention, since the underfloor storage box is fixed to the mounting base, even if water floods below the floor, the underfloor storage box will not float up and the floorboard will not be damaged. In addition, when securing the underfloor storage box with an L-shaped angle, a plate fixed to a recess in the circumferential wall is used, so even if the underfloor storage box receives buoyancy due to flooding, the width of the lower end of the plate is Since it is dispersed in the direction, it is not subject to concentrated force and does not cause any rattling at the mounting part. Moreover, since the recess into which the plate is locked projects outward, the plate, bolt heads, etc. do not protrude into the underfloor storage box, and a sufficient capacity can be ensured.
