Description

Circular storage tank and construction method

The present invention relates to a circular storage tank, and more particularly, to be manufactured by assembling a panel made of stainless steel can be assembled and installed more easily, at the same time to prevent corrosion as well as to the bottom of the storage tank The present invention relates to a circular storage tank and a method of constructing the sediment which can be easily discharged to the outside.

In general, the storage tank installed in the building is used in case of emergency in case of water or fire by storing water supplied from the outside in the tank, and in the case of general houses, such as FRP, concrete, steel, etc. Storage tanks with small materials are used, and large storage tanks made of stainless steel are used for simple water supply and large buildings.

The storage tank using the FRP, concrete, steel, etc. is inconvenient in construction, poor in watertightness and hygiene, weak in external impacts, so there is a high possibility of cracking or breaking, and it is impossible to recycle when disposing according to the service life. The incineration itself is prohibited due to the large amount of harmful substances generated in the human body during incineration treatment.

Recently, as the number of buildings such as large apartments increases, the demand for large-capacity storage tanks is increasing, and the storage tanks are manufactured by dividing several panels made of stainless steel and welding them together for the convenience of construction. Or they are assembled using fastening means such as bolts.

In the case of the storage tank made of such a stainless material, there is a problem that the cost of the manufacturing cost rises slightly, but it has high strength and is recyclable, and has excellent heat resistance and impact resistance as well as strong corrosion resistance.

However, when joining the stainless steel panel by welding, not only the construction is easy but also the brittleness of this part increases due to the change in the mechanical properties of the welded portion, so that cracks are generated and corrosion is easily generated. There is a problem of contamination.

Therefore, in recent years, a number of stainless panels are manufactured by dividing and assembling them by fastening means such as bolts. For example, Korean Patent Laid-Open No. 2001-0049248 (published on Jan. 15, 2015) As disclosed in, a plurality of fan-shaped panels, arc-shaped panels, packing members, and reinforcing members are used, and they are fastened to each other using a plurality of bolts and nuts.

In addition, the arc-shaped panel at the bottom of the tank is inclined toward the center, and a drain pipe is installed at the center thereof so that the sediment inside the tank is directly discharged to the outside through the drain pipe.

However, this tank structure can utilize the inherent properties of the stainless material and can be easily drained and cleaned, but since the upper and lower portions of the tank are conical, it is very difficult to be fixed to the concrete pad. Due to the nature, a number of vertical reinforcing bars must be installed in the center of the tank.

The present invention has been made in view of the problems of the prior art as described above, and an object of the present invention is to make it easier to work by dividing each member constituting the circular storage tank and to be stacked inside the tank. It is to provide a circular storage tank that can be easily discharged to the outside by the drain panel.

Another object of the present invention is to provide a construction method of a circular storage tank that can be easily assembled and installed in the field to make the members constituting the storage tank, to improve the structural stability to further increase the service life as well as to reduce the installation cost.
