Dual-function shock absorbing supporting structure for liquid storage tank

Abstract

The invention relates to a dual-function shock absorbing supporting structure for a liquid storage tank. The dual-function shock absorbing supporting structure comprises a plurality of columns made from profile steel. The bottom end of each column is welded to the bottom end of the liquid storage tank. The supporting structure also comprises pedestals and energy-consuming members, the numbers of which are consistent with the number of the columns, one end of each energy-consuming member is connected to the outer side surface of the corresponding column while the other end of each energy-consuming member is connected to the corresponding pedestal. Each pedestal is fixed to a mounting foundation, a horizontal restraint steel plate is connected between every two adjacent columns, and each horizontal restraint steel plate is horizontally mounted on the mounting foundation and is embedded into a groove of the connected column. Compared with the prior art, the dual-function shock absorbing supporting structure can reduce seismic response of a supported liquid storage tank structure and improve the anti-seismic property of the supported liquid storage tank structure, can be detached and replaced conveniently after disaster, restores normal use of the liquid storage tank quickly, and has dual functions that the dual-function shock absorbing supporting structure is not damaged in a small earthquake and can be replaced after a large earthquake.

Description

technical field [0001] The invention relates to the technical field of material storage and transportation, in particular to a dual-function shock-absorbing support structure for a liquid storage tank. Background technique [0002] In order to meet the increasing energy storage and demand, liquid storage tanks are widely used in practical projects. Due to the flammable and explosive properties of LNG, the construction and design of liquid storage tanks have strict requirements. The construction of large liquid storage tanks has become a development trend with the continuous advancement of technology. my country is located in the volcanic seismic belt around the Pacific Ocean, and most of the petrochemical industry is located in the earthquake area. As a sudden and highly harmful natural disaster, an earthquake may cause damage to the structure of the LNG storage tank, fire, Secondary disasters such as environmental pollution and explosions cause casualties and huge economic ...

AI Technical Summary

Problems solved by technology

The structural system has no energy-dissipating components, and it is prone to damage under earthquake loads. There are mainly two forms. One is that the tank wall at the welded part of the pillar and the tank body will undergo yield damage, and the other is that the pillar will undergo bending damage. Both will enter the plastic stage and cannot be repaired, and the liquid storage tank cannot continue to be used
