Description

Seismic prefabricated water tank with PE composite stainless steel plate edge reinforcement structure}

The present invention relates to a prefabricated water tank, and more specifically, to provide an earthquake-resistant designed water tank in a prefabricated form to prevent earthquake motion transmitted from the ground from being transmitted to the water tank, and to have an earthquake-resistant PE composite stainless steel plate edge reinforcement structure. This is about an earthquake-resistant prefabricated water tank.

In general, prefabricated water tanks aim to achieve structural stability by preventing earthquake motion from the ground from being transmitted to the superstructure.

In addition, prefabricated water tanks use multiple panels in the field and are provided in a cylindrical or box-shaped assembly structure to suit water storage.

These prefabricated water tanks are composed of a plurality of unit panels made of stainless steel (SUS) or other steel plates.

Here, the unit panel includes a frame that extends through the floor, side walls, and ceiling and penetrates the inside, depending on where it is installed in the prefabricated water tank.

In other words, the prefabricated water tank is composed of a water tank with a hexahedral outer wall by assembling the flanges of adjacent unit panels through mutual welding or fastening, and has the disadvantage of being easily damaged due to the pressure of stored water being concentrated at each corner.

Therefore, Patent Document 1 proposes a technology for improving the reinforcement performance of the side wall corners of a water tank by using corner reinforcement materials or corner reinforcement bars.

That is, Patent Document 1 constructs a wall assembled in a box shape by continuously connecting unit panels, and improves the strength of the side wall corners by combining corner reinforcement and corner reinforcement bars at the corners.

Therefore, we are minimizing welding work in order to prevent safety accidents at construction sites, and since fire accidents at construction sites are generally caused by welding, we are minimizing welding work as part of our efforts to reduce this. There is a trend towards no welding.

However, in Patent Document 1, the prefabricated water tank configures the side wall corners by bringing the flanges of the side wall unit panels of the square plate into direct contact with each other and then fixing the flanges by welding them, so it is difficult to minimize welding work, let alone non-welding. , there is a problem that the construction time is longer than before.
