Embedded shock-absorption steel frame for seismic hardening

Abstract

The invention relates to an embedded shock-absorption steel frame for seismic hardening, which is mainly applied to building seismic hardening. The shock-absorption steel frame is arranged at each layer of some spans of a building; the shock-absorption steel frame comprises an upper steel frame, a lower steel frame and a metallic yield damper; the upper steel frame and the lower steel frame respectively consist of a left part structure and a right part structure the relative positions of which are adjustable; the relative positions of the upper steel frame and the lower steel frame are adjustable, and after the position are well adjusted, the upper steel frame and the lower steel frame are connected through a bolt to form a rectangle frame; and the two ends of the metallic yield damper are respectively connected with the upper steel frame and the lower steel frame through bolts. The invention is explicit in force transmission; the cooperative work between the embedded shock-absorptionsteel frames of each layer and between the shock-absorption steel frame and a main structure is reliable; the harmful operation of carrying out shock resistance and shock absorption by means of eating off the anti-seismic bearing capacity of the existing pillars and nodes is changed; and the load of earthquakes on the existing main structure can be effectively reduced.

Description

technical field [0001] The invention relates to an embedded shock-absorbing steel frame for anti-seismic reinforcement, which is mainly used for anti-seismic reinforcement of buildings and belongs to the field of energy dissipation and shock absorption of civil engineering structures. Background technique [0002] At present, the most commonly used reinforcement method in the design of concrete structures is the enlarged section reinforcement method. However, the method of enlarging the cross-section reinforcement method has its disadvantages. For example, the wet operation time of on-site construction is long, which has a certain impact on production and life, and the internal space of the building is reduced after reinforcement, which affects its use function. Contents of the invention [0003] The object of the present invention is to overcome the above-mentioned defects of the reinforcement method with enlarged section, and propose a built-in shock-absorbing steel fram...
