Prefabricated Tank Structure

The present invention is for storing a variety of liquids (water, chemical liquids), and particularly relates to a prefabricated tank structure that is easy to manufacture, while having a rigid structure corresponding to the hydraulic pressure and bending load acted by the stored liquids. will be.

Previous prefabricated tank structures have been mainly manufactured as steel, and these steel tank structures have structural strength and rigidity corresponding to hydraulic pressure or bending loads applied from the inside due to their material properties, while liquid tanks stored therein Easily corroded, its service life was shortened, and due to the high cost of materials, the production cost was increased, and the installation and handling were difficult.

Recently, a prefabricated tank structure manufactured as a plastic panel has been developed and widely used.

As such, the prefabricated tank structure made of plastic material is relatively lighter in weight than steel, so it is easy to manufacture and handle, and the manufacturing cost can be reduced due to the low material cost. It is true that it has a positive advantage such as prolonging the service life since it can expect a beneficial effect on prevention.

However, the prefabricated tank structure of plastic material is deformed to the extent that the strain against the hydraulic pressure or bending stress applied from the inside is too large to maintain its original shape, and thus the tank structure cannot function faithfully. This is accompanied by the production of the connection bolt as a fastening bolt one by one, the work load is increased, and the productivity is accompanied with the drawbacks.

In order to overcome the above-mentioned problems, the present application is rectangular in shape and has a bottom plate portion horizontally placed on the bottom of the bottom, a cylindrical wall plate portion integrally joined to all around the bottom plate portion and extended to the upper portion, and above the wall plate portion. The bottom plate portion, the wall plate portion, the upper plate portion has been developed as a tank structure made of a synthetic resin hollow panel, each of which has a hollow portion therein as a hollow cross section.

Such a tank structure is manufactured as a synthetic resin hollow panel having a hollow cross-sectional structure with a large cross-sectional secondary moment per unit area, and has an advantage in that it can cope with hydraulic pressure or bending stress that is used from the inside as the cross-sectional performance is improved.

However, such a conventional tank structure is also unable to improve the characteristics of the synthetic resin material itself, so the lower part of the cylindrical wall plate that is subjected to intensive hydraulic pressure or bending loads from the inside is not curved, and deformed to the original shape Was not maintained correctly and, in severe cases, structural defects such as breakage of vulnerable joints of the cylindrical wallboard were caused.

The present invention is to structurally reinforce the wall plate portion in which the action force applied from the inside is concentrated, firstly to provide a rigid tank structure corresponding to the hydraulic pressure or bending load by the stored liquid, and secondly, to simplify the assembly installation work and To provide a tank structure that improves productivity by aiming for simplicity.
