Description

Synthetic resin tank structure and its manufacturing method

The present invention relates to a tank structure in which a liquid is contained therein, such as various large water tanks, septic tanks, chemical liquid storage tanks, and the like, and in particular, a tank structure made of a synthetic resin that has a more robust structural strength while efficiently manufacturing the structure. And a method for producing the same.

Various tank-type structures in which a liquid is contained therein are subjected to internal hydraulic pressure, large load from the outside, and earth pressure.

The tank structure manufactured as a synthetic resin can be expected to have an excellent effect in preventing leakage and corrosion, but it is deformed to maintain its original shape when subjected to great force from the outside because the strain against load and earth pressure is too large. It has been judged to be difficult to perform sufficiently.

In order to overcome this problem, the present applicant has both a bottom plate portion placed on the floor and a vertical cylinder portion whose vertical bottom portion is fixed to the bottom plate portion to be erected vertically in the shape of a cylinder. By fabricating a hollow panel made of synthetic resin in which hollow plates are integrally welded to form hollow portions, a structure having improved cross-sectional performance has been developed.

As such, the structure manufactured by using the hollow panel made of synthetic resin has an advantage of improving the ability to cope with vertical loads by improving cross-sectional performance.

However, the synthetic resin structure as described above does not fundamentally improve the properties of the synthetic resin material itself, so when a large hydraulic pressure acts inside the structure, or when a bending load such as earth pressure, which is buried in the ground and is transmitted from the outside, is applied. Severe structural defects have been found, such as the vertical cylinders failing to handle this, resulting in curvature of the original body, and failure to maintain the original shape.

In order to solve the structural defects of the structure, the present applicant is responsible for the internal hydraulic pressure or the external bending load by reinforcing the various reinforcing bars to the inner, outer, corners or joints of the wall plates forming the vertical cylinder portion. Reinforced synthetic resin tank structures have been developed and manufactured.

It is true that such reinforced plastic tank structures have a sufficient function to prevent deformation and breakage of the structure due to internal hydraulic pressure or external bending load.

However, the synthetic resin tank structure, which has been reinforced with reinforcing bars as described above, has not fundamentally solved the difficult joining operation between the members and the weak structure of the joining parts, which are problems that the structure originally had.

That is, in the above structure, first, the hollow panel is bent to join the bent part and the joint part of the vertical cylindrical part which is erected in the shape of a cylindrical body, and the fixing part which is fixed by joining and fixing the bottom plate part and the vertical cylindrical part by welding. At this time, the welding work is not only very demanding but also requires careful attention and cannot be performed by skilled welders, and the manufacturing cost of the structure is inevitably increased due to the long time required for the work. Secondly, since there are limitations in the plastic welding technology to date to join the spaced apart members, and secondly, joining the spaced members into a single rigid structure, the joints are often damaged even with the best welding to ensure watertightness and airtightness. Third, the bottom plate portion and the vertical problem is difficult to secure a reliable product By attaching reinforcements to the body, the construction period of the structure is delayed by the time required for the reinforcement of the reinforcement, and the appearance of the product is made coarse due to the presence of reinforcements scattered here and there. There were various problems such as being a big obstacle.

Accordingly, the applicant has a need to develop a new type of resin tank structure to solve the above problems.

The object of the present invention is to reinforce the hollow plastic panel made of synthetic materials used in the material of the structure, and to improve the joining method of the joints, first, to make it easier and faster production, second, to greatly improve the durability Third, to provide a reliability of the product, and third, to provide a synthetic resin tank structure and its manufacturing method that eliminates the obstacles to management in use because of its beautiful appearance.
