Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Application of the Invention] The present invention relates to a reinforcing structure for reinforcing a ceiling by fixing it to a side wall of a storage tank, and a structure of a reinforcing device thereof.

[Background technology]

So-called prefabricated storage tanks, which are installed on the roofs or basements of buildings, require extremely high earthquake resistance. (2) The bottom wall can be fixed to a frame that is fixed to the base, but for side walls that stand upright from this, there is no means to firmly fix the bottom wall, and the space between the opposing sides r4 The anti-ILv property was increased by installing ten/yonrondo and passing diagonal places between the side walls and the castle walls.

In recent years, external reinforcement methods have been developed to replace these so-called internal reinforcement methods, and the seismic performance of side walls has significantly improved. The ceiling wall, which is attached to the top of the side wall using bolts and nuts, has no effective means of improving seismic resistance. may occur.

[Purpose of the invention]

The present invention was developed in view of the above facts, and its purpose is to provide a storage tank reinforcement structure and its reinforcement structure that will not be destroyed even in the event of a major earthquake. ).

[Summary of the invention]

The storage tank ceiling reinforcement structure according to the present invention is constructed by connecting the flanges of the L-7' IC side wall panel with the flange facing outward. The upper part of the side wall is watertightly fixed to the bottom wall, and on the top of the side wall, 1. ',
1. r (n87 for ceiling panels with flanges)
In a storage tank formed by fixing flanges around the ceiling wall, which are connected with the runs facing inward, 1) at the top of the side wall.
This invention relates to an invention in which the flanges around the ceiling wall are fixed with nuts through the flange around the ceiling wall, and the four panels for the ceiling are bent at right angles from the flanges around the ceiling wall. The reinforcing device consists of 8 pieces with fixing holes to the flanges of the ceiling panel at the upper end, and 8 pieces bent at an internal angle at the lower end to the frame body which is in contact with the inner surface 1 of the side wall. It is characterized by having fixing holes in each of the eight pieces on the side wall.

Due to its ri-like structure, it was able to achieve its intended purpose without destroying the storage tank even in the event of an extremely large earthquake.
