Abstract

The invention discloses a concrete frame seismic reinforcement structure applying expanded metal. A to-be-reinforced concrete frame is formed by to-be-reinforced frame columns and to-be-reinforced frame beams. The expanded metal is connected between every two adjacent to-be-reinforced frame columns and every two adjacent to-be-reinforced frame beams on the same vertical plane respectively, constraint external members are fixed between the expanded metal and the to-be-reinforced concrete frame through connecting parts, steel with the yield strength smaller than that of the constraint external members is adopted in the expanded metal, and the connecting parts comprise high-strength bolts for connecting the expanded metal and the constraint external members and chemical bolts for connecting the constraint external members and the to-be-reinforced concrete frame. The constraint external members can improve the ductility of the to-be-reinforced frame columns. The expanded metal can improve the bearing capacity and energy-dissipating capacity of the to-be-reinforced structure. The concrete frame seismic reinforcement structure is used for structural reinforcement, the wet construction workload is small, the constraint external members can be prefabricated in a factory, only installation of the chemical bolts and the high-strength bolts needs to be completed on site, the industrial degree is high, construction is convenient and rapid, and the influences on normal use of a building are reduced.

Description

technical field [0001] The invention belongs to the technical field of anti-seismic reinforcement, and in particular relates to an anti-seismic reinforcement structure of a concrete frame. Background technique [0002] The frame structure is a structure composed of beams and columns that jointly resist the horizontal and vertical loads that occur during use. It has the advantages of flexible space separation, light weight, good for earthquake resistance, material saving and flexible building layout. Large use space, often used in teaching buildings, residential buildings, office buildings and commercial buildings. In recent years, there have been many strong earthquakes around the world, which have caused great harm to local buildings, economy and people's lives. It is a difficult problem to be solved urgently to inspect and strengthen the post-earthquake buildings to ensure their normal use during the remaining service period. [0003] At present, the commonly used anti-s...
