Installation and construction method for energy-dissipating type buckling-restrained brace

Abstract

The invention discloses an installation and construction method for an energy-dissipating type buckling-restrained brace. The method comprises following steps: installing embedded parts, installing gusset plates, connecting supports and filling a wall body and the like. The embedded parts are made in the manner that webs are utilized for opening H-type steel plates. The gusset plates and the supports are installed in a high-precision welding mode. After a wall body is filled, a galvanized steel wire net is arranged in order to prevent cracks of the wall surface. The installation and construction method for the energy-dissipating type buckling-restrained brace has following beneficial effects: by adoption of a construction method, installation of the energy-dissipating type buckling-restrained brace is convenient and rapid so that anti-seismic performance of the supports can be given into full play and operation and construction can be conveniently carried out; an application scope of the energy-dissipating type buckling-restrained brace in the building construction is broadened so that anti-seismic performance of the structure is ensured, engineering quality is ensured and the anti-seismic performance of the overall construction is enhanced; when a slight earthquake occurs, the wall surface is not easily cracked so that aesthetic property of a building is ensured; meanwhile, little material is consumed so that the installation and construction method is of great popularization and application value.

Description

technical field [0001] The invention relates to the field of construction engineering, in particular to an installation and construction method of an energy-consuming buckling restraint support. Background technique [0002] Our country has a vast territory and is also a country where various natural disasters occur frequently, and earthquake disasters are one of them. With the continuous progress of society and the development of national economy, people have higher and higher requirements for improving the ability of public buildings to resist earthquake disasters and reducing casualties and property losses in earthquakes. In the method of improving the seismic capacity of structures, buckling-restrained braces are efficient, economical, and high-tech new structural members that can combine load-bearing members and energy-dissipating shock-absorbing members. By taking restraint measures on ordinary steel supports, it can Compressive buckling is completely avoided, and the...

Problems solved by technology

[0003] There are many types of buckling-restrained braces, including bearing-type buckling-restrained braces, energy-dissipating buckling-restrained braces, and buckling-restrained brace dampers. Among them, energy-dissipating buckling-restrained braces have the most obvious anti-seismic effect and are the most widely used, but their installation is relatively difficult. The precision requirements are high, many supports do not achieve the ideal anti-seismic effect, and some walls with supports are prone to cracks or wall peeling.
