Description

CYLINDER TYPE STORAGE TANK WITH CURVEDLY AND VERTICALLY EXTENDED PANEL ASSEMBLY STRUCTURE}

The present invention relates to a cylindrical storage tank of a curved vertical extension panel coupling structure, and more particularly to a cylindrical storage tank of a curved vertical extension panel coupling structure that is easy to manufacture the panel, easy to assemble and mass-produce.

In general, the cylindrical storage tank is for storing oil, living and factory water, drinking water, etc., and provides a structural characteristic that can support the internal pressure more effectively and stably than the rectangular storage tank, and its material is made of stainless steel Because of the use of the material, it is possible to suppress the growth of bacteria and the generation of moss, and keep the stored water clean.

The present applicant can efficiently manufacture in an automated factory and can provide a minimum welding line through an easy manufacturing method, but in order to ensure the stability of the product and to minimize the use of expensive stainless steel materials in an optimal design Much research and effort have been made to calculate the thickness.

As a result, the applicant has filed a patent in Korea and registered in 2001 after applying for its dual application in the `` cylindrical storage tank and manufacturing method thereof '' of the registered utility model No. 246330 (Technology Evaluation Maintenance Decision Clause 1-5). By stacking cylindrical units in multiple stages and welding them, high-altitude work was relatively easy.

In addition, the present applicant is a device and method for manufacturing a flanged cylindrical unit of a storage tank of 2001 Patent Application No. 17648 and a flanged cylindrical unit manufactured by the same, and the multi-layer flange type of a storage tank of the same patent application No. 18184 Cylindrical unit manufacturing apparatus and method and a multilayer flanged cylindrical unit manufactured by the same are devised.

The manufacturing apparatus used in this application can vertically fold both flange parts integrally and horizontally in sheet metal processing by vertically standing strips of stainless steel or composite steel. If the flange bending machine is removed from the manufacturing apparatus, the left and right flange sides may be integrally formed on the left and right sides of the flat body surface.

In particular, 2001 Patent Application No. 18184 has a flange bending machine that can bend the upper and lower flanges of the cylindrical unit at an acute angle. If a plurality of rolls capable of forming a corrugation in the flange bending machine is mounted, it will be possible to process the sheet metal body into a corrugated body surface.

Stainless steel compact water tank according to the prior art is filed on July 16, 2003, as shown in 2003 Utility Model Registration No. 328909 and Figure 1, it is formed in a circular shape of a certain width, the center protrudes a predetermined height upwards A support plate 1 having a curved surface formed thereon and having a reinforcing pipe supporting the curved surface; A cylindrical body (2) seated around an upper surface of the support plate (1) to form a space therein; It is characterized in that the cover 3 is seated on the cylindrical body 2 upper surface to block the inside, the outside is fixed by welding.

Here, each cylindrical body 2 is laminated in multiple stages, and forms a support piece 2b like a flange bent outwardly on the upper and lower sides in the height direction of the cylindrical stainless circumferential surface 2a. And the fixing pieces 2c are formed at both ends in the longitudinal direction so as to be rolled in a circular shape, and then, the outer surface of the circumferential surface 2a has the width of the support pieces 2b and the fixing pieces 2c. The heat insulating material 4 is attached.

However, the cylindrical storage tank according to the prior art has been disclosed in the registered Utility Model No. 246330, in which the present applicant has been registered and whose rights are valid, and since the unitary cylindrical body is laminated in the height direction, The welding line in the direction is formed in plural wherever the cylindrical bodies are stacked.

That is, the plurality of circumferential welding lines are formed in the height direction as a layer, and maintain a gap corresponding to the height of the cylindrical body.

However, the hydraulic pressure in the cylindrical storage tank of the prior art can be calculated by multiplying the specific weight of the water by the height, and for this reason, the cylindrical storage tank of the prior art can be stored as can be seen through the conventional structural analysis Very sensitive and vulnerable to the effects of height.

At the same time, as the height of the cylindrical storage tank increases in the height direction, the number of welding seams in the circumferential direction increases while maintaining a predetermined distance in the height direction, so that structural stability, yield yield factor, or breakdown safety factor design in the height direction is very difficult. It is true.

Therefore, when the cylindrical storage tank according to the prior art is small in height and large in diameter, the number of welding lines in the circumferential direction may not be relatively increased in the height direction and thus may be suitable for large diameter structures.

However, it is very difficult to secure structural stability due to the relatively high number of circumferential weld seams and high heights under conditions requiring a relatively large amount of water at a location where only a small installation area is allowed. It is a situation that can not only be manufactured at a high cost by using a separate, the additional reinforcement shaft to be attached by welding, there is a disadvantage in that a lot of unnecessary welding line is formed in the circumferential direction or the height direction.

In addition, the cylindrical storage tank according to the prior art has a disadvantage in that it is very uncomfortable and difficult to stack the cylindrical body of a much heavier cylindrical body in the height direction than the panel.

That is, stainless steel strips, which are made of cylindrical storage tanks, are usually used to have a width of 1 meter. Therefore, the height of the cylindrical body has a height of 1 meter or less in consideration of the support piece such as the flange.

In this situation, in order to perform the installation of the storage tank with a total height of 4 meters, a separate construction facility for lifting each of the four cylindrical bodies, which are relatively heavy compared to the vertical extension panel of the present invention, is required at the construction site. The construction of a heavy object can not ignore the risk of a safety accident.

It is an object of the present invention to provide a cylindrical storage tank of a curved vertical extension panel coupling structure that is easy to install and very economical by welding a plurality of vertically extending panels that are relatively light and easy to handle in a storage tank construction site.

In addition, another object of the present invention is by the curved vertical extension panel coupling structure, it is possible to configure a relatively high water tank compared to the plane area, to ensure the durability and safety of the water tank with a relatively high height, The present invention provides a cylindrical storage tank having a curved vertically extending panel coupled structure that can solve the problem that the water pressure generated during the storage of water is very sensitive and vulnerable to the influence of the reservoir height.
