Metal tank with a synthetic resin sheet, and unit panel

Abstract

The present invention relates to a metal tank with a synthetic resin sheet, which comprises a tank body constructed of a plurality of a first unit panels installed to form a bottom surface of the tank body, each of the first unit panels being made by stacking a synthetic resin sheet, a first metal plate, and a thermal insulation material in order, and a plurality of second unit panels installed to correspond to edges of the first unit panels and to form side surfaces and an upper surface of the tank body, each of the second unit panels being made by stacking the synthetic resin sheet, the first metal plate, the thermal insulation material, and a second metal plate in order; a plurality of stay reinforcement members, respective both ends of which are installed at edges of the first unit panels and edges of the second unit panels constituting a ceil surface of the tank body; a plurality of beam reinforcement members, respective both ends of which are installed at opposing edges of the second unit panels constituting the side surfaces of the tank body, the respective beam reinforcement member being partially welded to the respective stay reinforcement member; and securing means provided to secure the corresponding edges of the adjacent unit panels to the outside wall of the tank body, to thereby accomplish the metal tank, which is harmless to the human body, good in durability and waterproof property without using the high-cost stainless steel, and can increase the productivity of work by using a color steel plate to the second metal plate to thereby remove separate melt plating or painting.

Description

TECHNICAL FIELD [0001] The present invention relates to a metal tank with a synthetic resin sheet, in particular to a metal tank with a synthetic resin sheet and a unit panel for it, which is constructed by engaging a plurality of unit elements in correspondence with the desired volume, each of which is fabricated by attaching a polyethylene sheet harmless to the human body on a portion of one surface of a galvanized iron plate and filling a urethane resin between the other surface of the galvanized iron plate and a metal plate, thereby ensuring excellence in cost competitiveness and waterproof property and durability while being harmless to the human body. BACKGROUND ART [0002] In general, a rubber lining is good in chemical-resistant property, wear resistant property, high adhesion property, high reliability, and high construction property, as well as economic anti-erosion processing, and easy in repair and maintenance of the defect portions during the use, in comparison with the ...

AI Technical Summary

Benefits of technology

[0019] According to the first embodiment of the present invention with the structure described above, it is possible to implement the metal tank, without using high-cost stainless steel, which is harmless to the human body and excellent in durability and waterproof property, and it is good in workability because a painted color steel plate is used in the second metal plate to remove the necessity of separate melt plating or painting.

[0020] Also, in the present embodiment, it is possible to reduce production cost and clean the inside of the tank easily because separate internal reinforcing work is not required, dissimilarly to the SMC tank or the water purifying tank made of the stainless steel.

[0021] In addition, in the present embodiment, workability is good because no welding work is carried out in the inside of the tank, and it is very advantageous for making the tank requiring sanitary work as is in the water purifying tank.

[0022] Further, according to another embodiment of the present invention, it is not only possible to improve the durability by radically preventing the peeling of the interface through the foaming of the polyethylene without using the adhesives, but also to accomplish desirable thermal insulation performance by preventing the compression of the thermal insulation material by means of the engagement member.

[0023] Also, according to the embodiment of the present invention, it is possible to reduce the production cost because the first metal plate is not used in the second unit panel of the metal tank.

Problems solved by technology

In the case of the water purifying tank made of the concrete structure, water-proof structure is accomplished by carrying out a paint after constructing a mortar mixed with a water proof solution at the inside wall surface of the concrete tank, however, cracks can be produced due to the repeated expansion and contraction of the concrete so that rubber lining is requisitely required.

Further, in the case of the water purifying tank made of the metal material, rubber lining is not constructed in the inside of the tank without at the ceiling surface in which the chloride can be remained, and it uses a harmless stainless steel.

However, in such a water purifying tank constructed of the stainless steel, it is not cost competent because the cost of the material for the tank is high.

In addition, such a water purifying tank made of the stainless steel is provided with a plurality of separate reinforcement angles to reinforce the side portion at the inside and the corner portion to thereby increase the production cost as well as the complexity of the use, making it difficult to clean and wash.

Such technology is excellence in hygiene property and earthquake resistant property, however, it is low in cost competitiveness because a special mold is required.
