Description

[Detailed Description of the Invention] [Technical Field] This invention relates to a mounting structure for an underfloor storage that utilizes the area under the floor to store stored items.

[Background technology]

Conventionally, in large under-floor storage rooms where people can enter and take out stored items, anchor bolts have been planted in the foundation concrete layer formed on the sub-floor surface in order to prevent floating due to sub-floor water seepage. The bottom piece of the underfloor storage is secured to this anchor bolt with a nut. However, because nuts were fastened to the anchor bolts inside the underfloor storage, water that had flooded under the floor or groundwater could enter the underfloor storage through the anchor bolts, resulting in poor waterproof performance. Was.

[Purpose of the invention] The purpose of the invention is to provide a mounting structure for an underfloor storage that can prevent floating due to underfloor water seepage and also has excellent waterproof performance.

[Disclosure of invention]

The mounting structure of the underfloor storage of this invention is that a recess is provided at the lower part of the outer surface of the underfloor storage, a bolt insertion hole is provided in the fixing piece consisting of the bottom piece of this recess, and the bolt is inserted into the foundation concrete layer into the bolt insertion hole. It is characterized by being fastened with a nut through an anchor bolt.

An embodiment of this invention will be described with reference to FIGS. 1 and 2. That is, as shown in both figures, the installation structure of this underfloor storage is such that anchor bolts 2 are planted in the basic concrete layer 1 formed on the subfloor surface, and anchor bolts provided in the fixing pieces 4 of the underfloor storage 3 are inserted. Pass the anchor bolt 2 through the hole 5,
A nut 7 is fastened to the anchor bolt 2 via a ring-shaped plate 6.

To explain in detail, the underfloor storage 3 has an entrance 8 at the top.
A box-like main body 9 having a main body 9, a mesh basket 10 that can be attached to and detached from the entrance 8, and a lid 11 that can open and close the entrance 8. The box-like main body 9 has storage sections 12 on all sides, one storage section 12 has a shelf board 13 that also serves as a staircase, and each storage section 12 has a stove 14, an electric fan 15, a travel bag 16, and a drink 1.
7. It is possible to store items such as the iron holder 18. Further, a recess 19 opening outward is provided at the lower part of the outer surface of each storage portion 12, and a bolt insertion hole 5 is provided in the fixing piece 4 constituting the bottom piece of each recess 19, so that each fixing piece 4 can be inserted as described above. Attach nuts to anchor bolts 2 respectively. In this case, the bottom piece 9a of the main body 9 is placed on the foundation concrete layer 1. Note that the entrance/exit 8 is connected to an opening formed in a floor surface (not shown).

In this way, the underfloor storage 3 is fixed to the foundation concrete layer 1 by passing the anchor bolt 2 through the bolt insertion hole 5 of the fixing piece 4 and tightening the nut 7. Since it is stopped, water that has flooded under the floor or underground water can be reliably prevented from penetrating into the underfloor storage 3 through the anchor bolts 2. Of course, it goes without saying that it is possible to prevent the underfloor storage 3 from floating due to underfloor flooding.

Further, the fixing piece 4 consists of a bottom piece of the recessed part 19,
It does not protrude from the outer surface of the main body 9. Therefore, it is easy to transport, there is no wasted space in the packaging case, and it can be stored compactly.

Furthermore, the fixing piece 4 is not damaged during handling and is easy to handle.

[Effect of idea]

According to the mounting structure of the underfloor storage of this invention, it is possible to prevent the floorboard from floating due to water seepage under the floor, and it is also possible to obtain the effects of excellent waterproof performance.
