Description

DETAILED DESCRIPTION OF THE INVENTION "Field of Industrial Application" This invention #i relates to an underground low temperature warehouse that is easy to construct and has low running costs.

"Conventional Technology" Conventionally, low-temperature warehouses that use underground spaces as storage locations are known. In this underground warehouse, the temperature and humidity in the underground space remain almost constant throughout the year, and the heat capacity of the ground itself is large, so it is not susceptible to fluctuations in outside temperature and humidity, and as a result, storage costs are low. This kind of underground warehouse has the advantage of being easy to use! , an internal IC5lI ice bit is installed, and this ice making pit stores cold heat using outside cold air in winter or cheap late-night electricity, and uses the cold energy to keep the inside of the refrigerator at a constant low temperature.

``Problem to be solved by the invention'' In the above-mentioned underground cryogenic warehouse, if the ground is rock-like, which is structurally safe, this will not be much of a problem.
If the ground is other than bedrock, there will be problems with the strength of the structure of the underground space if it is left as is, so it is necessary to pour concrete into the walls, floor, and ceiling of the underground space on which circular surface for reinforcement. , which has traditionally been done.

By the way, when pouring concrete, it is naturally necessary to transport the concrete formwork, but as is well known,
The formwork is relatively large in size and volume, making loading and unloading operations complicated.Moreover, in the limited underground work space, various restrictions arise, making the work difficult and increasing the number of construction man-hours. ing.

This invention was made in view of the above circumstances, and aims to provide an underground low-temperature warehouse that has low running costs and is easy to construct.

"Means for Solving Problems" The underground low temperature warehouse according to the present invention replaces the conventional formwork,
A formwork is used that has a container shape that can store water inside and can be connected to each other in the vertical and horizontal directions.The formwork with this shape is used to pour reinforcing concrete, and the formwork Fi is dismantled. Instead, one of the molds was left as is, water was poured into the molds, and many of these molds were used as ice-making pits.

"Function" According to the above configuration, each formwork is formed into a hollow container shape that can be filled with water, so it is small and easy to transport and assemble at 04F, and can also be used as an #ia ice pit after concrete pouring. This eliminates waste and eliminates the need for carrying out the work, making it possible to significantly reduce the number of man-hours required for trench construction.

Hereinafter, this invention will be explained in more detail with reference to Examples.

"Embodiment" FIG. 1 shows an embodiment of the present invention, and reference numeral I in the figure shows an embodiment of the present invention.
This shows an underground space where Fi is stored. Concrete 2 is poured to reinforce the inner wall surface 1 &VC#'i of this underground space 1, and inside the concrete 2, there is a formwork c of a special structure used at the time of pouring, and a formwork that also serves as a cold storage heat source. A large number of tanks (referred to as tanks) 3 are connected and fixed to the inner wall surface.

This formwork and cold storage heat #i13 is shown in Figure 142 (~, (h)K
As shown, it is a box-shaped container whose periphery is sealed, and its upper, lower, left, and right surfaces each extend outward in the shape of a brim to form a seven-rank portion 3a for connection. This 7 rank part 3aK
Fi, bolt holes 4 for connecting a large number of formwork/cool storage heat tanks 3 to each other vertically and horizontally are bored. Also,
This formwork and cold storage heat tank 3 is provided with a water supply port and a drainage port (not shown), so that treated water can be stored inside after installation.

Therefore, this formwork/cold storage heat M3 is connected in large numbers along the inner wall surface of the underground space l and fixed with a large number of anchors 5, 6 for pouring reinforcing concrete. Even after installing the concrete 2 between the tank 3 and the inner wall surface 1, it can be left as is and used as an ice making pit. As described above, after the formwork and cold storage heat tank 3 is installed, even if it simply stores water, it can store cold heat when cold air from outside enters the chamber in winter, but when using cold air from outside, , 1II of this formwork
IJ! ! If you install a heat pipe that thermally connects the IfK interior and the water storage, or provide an outside cold air introduction hole in the ground to directly introduce outside cold air into this formwork and cold storage heat tank 3, it will be even better. Efficient cold storage and heat storage can be performed. Also, when storing cold heat using late-night electricity, is it possible to store it outside the refrigerator? T? An r-freezing machine may be installed to make ice in the formwork/cold storage heat tank 3 via a prine.

As mentioned above, the formwork and cold storage heat tank 3 is a small hollow container, so it is lightweight and easy to transport, and the formwork is easy to assemble, and after concrete is poured, it can be left as is. By injecting water inside, it can also be used as an ice making pit for storing cold heat, making it easy to disassemble the formwork and
There is no need to carry out the work, and the number of man-hours required for R4 construction can be significantly reduced.

In the above embodiment, the shape of the formwork and cold storage heat tank is cylindrical, but it is not limited to this shape, and other shapes may be used as long as they exhibit the same effect. for example,
If the shape is a hexagonal column with a hollow short axis, the structure becomes a so-called honeycomb structure after the formwork is assembled, so that a high-strength underground structure can be constructed. Therefore, there are only methods for constructing an existing underground space or an underground space #C after excavation, for example,
A dome-shaped hollow monument with a honeycomb structure is formed by combining the short-axis hollow hexagonal column-shaped frame and cold storage heat tank in a large depression.Concrete is poured on the outside of this structure, and finally it is covered with earth and sand. By filling in the depression mentioned above, a relatively large underground low-temperature warehouse with a capacity of 8 and Q can be constructed. At this time, water was injected into the formwork to be used as an ice-making pit only on the side walls, and water was not poured into the ceiling for 1 minute to maintain the overall strength. It is desirable to keep it.

"Effects" As explained above, the underground low temperature warehouse of the present invention has a construction formwork shaped like a hollow container that can be filled with water, so it is small and easy to transport and assemble in one piece. After concrete is poured, it is used as an ice-making bit, so there is no waste, and there is no need to carry it out, so it has the advantage of significantly reducing construction man-hours.
