Description

Prefabricated polyethylene double frame water tank

The present invention relates to a prefabricated PDF water tank, and more particularly, a through hole is formed in a portion where the synthetic resin hollow panel and the synthetic resin hollow panel are in close contact, and then a fixing bracket is inserted, and the side wall portion and the horizontal reinforcing portion are formed through bolts and nuts. And because the outer bracket is firmly fixed, it reinforces the flexural strength to prevent deformation of the synthetic resin hollow panel, and because the PE sheet is heat-sealed while covering the fixed part on the bottom and sidewalls, leakage is effectively prevented during shrinkage expansion or structural deformation. The present invention relates to a prefabricated PDF water tank that not only prevents, but also simplifies the configuration of devices for internal and external reinforcement of the prefabricated water tank to secure economic efficiency.

In general, prefabricated water tanks are storage containers that store a certain amount of water and supply it to buildings that use a lot of water for living, such as residential apartments and business buildings, and these are stainless panel tanks and synthetic resin (SMC) panel tanks depending on the material. , Concrete tank, etc.

The stainless panel water tank is formed by cutting and pressing a stainless steel plate of a predetermined thickness to a certain standard to form an embossing, and bending the flange of the edge to form a unit panel. Each side of the unit panel is joined by argon welding. After forming in the shape of a case, a panel tank is formed to reinforce horizontal reinforcing material at each corner of the corresponding unit panel.

However, the stainless panel water tank has a problem in that the manufacturing cost increases due to the increase in the cost of raw materials, and the welding part of the stainless steel is corroded by the chlorine gas contained in the tap water, so its durability is poor, and during argon welding, the stainless steel plate material due to high temperature heat. There is a problem that corrosion occurs in a short time due to the destruction of the corrosion resistant layer of the passivation film on the surface.

In addition, the synthetic resin (SMC) panel water tank forms a unit panel with a mold by combining a filler, a catalyst, and a glass fiber with a polyester resin, and fastening with bolts/nuts while the gasket is in close contact with the flange of the unit panel. After forming in the shape of a case, a panel tank is formed to reinforce with horizontal stiffeners at each corner of the corresponding unit panel.

However, in the synthetic resin panel tank, the tensile and flexural strength of the unit panel is weak to about 1/4 of that of the steel plate, so in order to maintain the same tensile and flexural strength as the steel plate, the thickness of the unit panel must be relatively thicker than that of the steel plate. There was a problem that the manufacturing cost increased due to the increase, and the gasket is tightly attached between the unit panel and the unit panel, and it is completely fixed by tightening with bolts/nuts. However, due to the hardening of the gasket, the bolt/nut tightening part becomes loose and leaks. There was a problem that occurred.

In order to solve the above problems, a large-capacity water tank has been registered as Korean Utility Model Registration No. 20-0371267.

The pre-registered utility model is a configuration in which a vertical member and a reinforcing member are welded on-site to form an enclosure, and a hollow resin plate is installed inside, and then a waterproof sheet is heat-sealed. There was a problem in that the manufacturing cost was increased due to excessive steel frame material consumption, and there was a problem in that economic feasibility was decreased due to the increase in time due to the complicated work process.

Recently, in order to solve the above problems, a prefabricated water tank using a synthetic resin hollow panel has been registered as Korean Patent No. 10-1455819.

The pre-registered patent is assembled by placing the floor panel in a grid shape on the stems spaced at regular intervals and forming a side wall part using a synthetic resin hollow panel, and fixing a sealing member between the hollow panel and the hollow panel. There is an advantage of solving the above problems by simplifying the process, but the synthetic resin hollow panel is deformed and cracked due to high water pressure, and the bolt penetrates through the four elements to fix the inner bracket and the outer reinforcement part. There was a problem in that water leakage frequently occurs whenever the low and high water levels change.

In addition, there is a problem of water leakage due to frequent cracks in the synthetic resin hollow panel at the edge where the shrinkage and expansion stress is concentrated according to the water level fluctuation of the water tank.
