Description

[Detailed explanation of the invention] "Industrial application field" This invention is a method for underground storage, which is buried underground, for example, in a building, and is used to store and store goods in order to make effective use of the land. It is related to storage.

``Conventional technology'' Traditionally, in order to install an underground storage, a hole of a certain size is dug in the ground, a formwork is constructed in the desired shape, concrete is poured into the hole, and then concrete is poured into the hole for a certain period of time. After waiting for the concrete to harden, the formwork was removed and the construction was completed.

``Problem that the invention seeks to solve'' With the above structure, after digging a hole in the ground, the formwork is assembled, concrete is poured, and after waiting for the concrete to harden, the formwork is replaced. Since the removal work has to be performed, the construction period becomes longer and the work is also very troublesome.

``Means to Solve the Problem'' Therefore, the present invention has a box-shaped upper and lower frame that is open on one side, made of cement concrete mixed with reinforcing fibers such as glass fiber, and whose periphery is slightly protruded. , this part is polymerized and fixed, and the bottom of the lower frame is a gently sloped surface toward the center, with a water collection recess formed in the center, and at regular intervals on the outside, inside, ceiling, and floor of the upper and lower frames. A reinforcing strip is formed and an entrance is formed in a part of the ceiling, and this is manufactured in advance in a factory, assembled, and transported to the site for construction, which greatly shortens the construction period, and Since it is made of cement concrete reinforced with glass fiber or the like, the member thickness can be made thinner, and the above-mentioned disadvantages can be solved by making it possible to construct it strongly and inexpensively.

Its structure will be explained with reference to the drawings. 1 and 2 are box-shaped upper and lower frames that are open on one side, and are made of cement concrete mixed with reinforcing fibers such as glass fibers, and have projecting edges 3 and 4 slightly outward on the periphery. It is formed. A protrusion 5 is formed on the inner upper surface of the protrusion 4 of the lower frame 2, and a protrusion 6 is formed on the outer upper surface of the protrusion 5 of the upper frame 1.
When the projecting edges 3 and 4 of 2 are overlapped, the projecting ridges 5 and 6 are shifted and overlapped, and the projecting edges 3 and 4 are provided with bolt holes at appropriate intervals, and a bolt 7 is inserted through these holes and a nut 8 is inserted.
Alternatively, the projecting edges 3 and 4 may be polymerized and fixed using a strong adhesive. Reference numeral 9 denotes the bottom surface of the lower frame 2, which is a gently sloped surface toward the center, and a water collection recess 10 is formed in the center. 11 is the upper and lower frames 1 and 2
12 is a reinforcing strip provided on the ceiling surface of the upper frame 1, and 13 is a reinforcing strip provided on the inner bottom surface of the lower frame 2 and its periphery. Reference numeral 14 denotes an entrance provided in a part of the ceiling of the upper frame 1. 15 is an exhaust hole. 16 is a staircase, 17 is an exhaust pipe attached to the exhaust hole 15, 18 is a foundation, 19 is mortar, 20 is an embedded bolt, 21 is a mounting bracket, one side of which is fixed to the embedded bolt 20 with a nut 22, and the other The sides are fixed with bolts 23 by screwing into bolt holes of projections 24 provided on the outside of the bottom of the lower frame 1. 25 is the bottom frame 2
This is a floorboard placed on the reinforcing strips 13 on the bottom of the.
26 is the floor of the building, and 27 is a packing material interposed between the projecting edges 3 and 4. 28 depending on need,
This is a heat insulating material inserted inside the upper and lower frames 1 and 2.

"Function" Since the present invention has the above-mentioned structure, in order to construct it, a foundation 18 is provided at the bottom of the hole that has been dug, a mortar 19 is placed on top of the foundation 18, and the product of the present invention is placed on it. At the same time, the mounting bracket 21 is attached to the embedded bolt 20 with the nut 22.
Fix the other side of 1 to the lower frame 2 with bolts 23,
Construction is carried out by backfilling with earth and sand, and installing exhaust pipes 17, stairs 16, and floorboards 25.

``Effect of the invention'' The invention of the invention has the upper and lower frames 1 and 2 made of cement concrete mixed with reinforcing fibers such as glass fibers, so it is lightweight, strong, durable, and It has excellent fire resistance and heat insulation, and the reinforcement strips 11 on the outside, the reinforcement strips 12 on the ceiling surface,
The thickness of the upper and lower frames 1 and 2 can also be reduced by the reinforcing strips 13 on the floor and its periphery. Since this invention is produced separately in the factory into the upper and lower frames 1 and 2, the quality is stable, and since they are only joined at the factory and buried on site, construction can be done quickly and the construction period can be shortened. be able to. In addition, the bottom surface is a gently sloped surface, and the center thereof is a water collection recess 10, so water is collected in the water collection recess 10, and is either wetted with cloth and discharged to the outside, or Since it can be discharged by water, there is less humidity indoors, and since it is underground, it can escape from fire, and it is effective as a storage space for goods.By installing it in the basement of a building, land can be used effectively. It has the following effects.

In addition, by attaching the present invention to the base 18 via the attachment fittings 21, it can be firmly fixed. Further, by installing the exhaust pipe 17, it is possible to further prevent moisture inside the room, and by providing the stairs 16, it is possible to make going in and out easier. Further, by interposing the packing material 27 between the projecting edges 3 and 4, the airtightness is improved, and by fixing them with the bolts 7 and nuts 8, they can be firmly fixed.
