Description
- 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.
- 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 other organic and inorganic anti-erosion materials, so that it occupies a unique position in the field of the anti-erosion processing and over whole industrious field in spite of the conspicuous development of the plastic industries.
- Conventionally, the rubber lining is one of the anti-erosion technologies about the several chemicals including the sulfur oxides (SOx), nitrogen oxides (NOx), and the other harmful gases, which reduce the durability of the iron reinforced concrete and the other structures, and is one of the high-tech anti-erosion method applied to the facilities for preventing the air pollution, facilities for processing the waste waters, the water processing facilities, and the other chemical facilities. Especially, the water-purifying tank employs the rubber lining technology to carry out the water-proof processing in the inside of it.
- Here, the rubber lining is divided into two types, one of which is to form a desired thickness of thick films on the inside wall surface of the water purifying tank by spraying the synthetic resin, and the other type is to attach the synthetic resin sheet.
- In general, the water-purifying tank can be divided into a concrete structure, which is excellence in construction property and cost competitiveness, and a metal water purifying tank.
- 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. Also, in such a concrete structure type water-purifying tank, the rubber lining should be repaired and conserved by a predetermined period due to its particular repeated expansion and contraction.
- 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.
- In order to solve such problems, in Korean Utility Model Registration No. 1,358,000 (Res. date: 1998. 11. 06), there is disclosed a large water tank made of the synthetic resin materials. In this invention, the large tank made of the synthetic resin materials has been manufactured by spraying the polyethylene resin at the inside wall of the of the tank made of the synthetic resin materials, so that the structural defects of the concrete structure can be solved and it has a cost competitiveness in comparison with the water purifying tank made of the stainless steel structure, however, it is very low in durability against the outer force in comparison with the concrete structure and the water purifying tank made of the stainless steel structure. Especially, as for the large or mid scale tank with a big static load or big dynamic load, it has been required that particular reinforcement technology be applied to the inside and outside of the tank.
- Another technology to solve such problems is a SMC (Sheet Molding Compound) tank, in which resin coating is applied to the metal plate made of the stainless steel or steel. Such technology is excellence in hygiene property and earthquake resistant property, however, it is low in cost competitiveness because a special mold is required.
- Accordingly, the structure of the present water purifying tank is urgently required that it is excellence in cost competitiveness as is the concrete structure, and is harmless to the human body as is the stainless steel as well as of a structure not requiring the repair and conservation.
- Technical Problem

Here, the detailed explanation about the sectional structure and constitution of theunit panel 500 will be abridged because they have been explained inFIGS. 7 and 8 . - With regard to the engagement, the engaging
screw 630 b passes through the engagement hole of the engagingreinforcement member 630 a, the through-hole of theengagement member 550, and the engagement hole (no numeral) of thereinforcement member FIG. 5 , with the upper surface of the engagement hole in theengagement member 550 be hermetically sealed thesynthetic resin sheet 561, the engagingscrew 630 b penetrates through thesynthetic resin sheet 561 and passes through the engagement hole of theengagement member 550. In this regard, thesynthetic resin sheet 561 functions as a packing for sealing. - The present invention is constructed that the
engagement member 550, which is made of the rigid body, supports theunit panel 500 so that it is not compressed, at the time of the engagement of theunit panel 500 and thereinforcement members - Although the present embodiment only has explained about the
second unit panel 500, as the same explanation can be applied to the first embodiment, the detailed explanation about it is abridged. Whereas, the only difference existed between the first andsecond panels FIG. 13 ). -
FIG. 11 is a cross-sectional view showing a portion of the metal tank shown inFIG. 9 .FIGS. 12 and 13 are enlarged cross-sectional views of the portions “A-1”, and “B-1”. - Referring now to FIGS. 11 to 13, the metal tank of the present invention is consisted of the
