Lifting installation system for buckling restrained supporting member and construction method thereof

Abstract

The invention provides a lifting installation system for a buckling restrained supporting member and a construction method of the lifting installation system for the buckling restrained supporting member. In the installation system, chain blocks used for lifting the buckling restrained supporting member are fixed to a beam or supporting stand columns of the buckling restrained supporting member to be installed respectively through hanging plates or temporary supports. The hanging plates and the temporary supports are simple in structure and can be used repeatedly, construction is convenient, manpower and material resources are saved, and the problems that in the current construction, the rate of progress is low, the construction can be finished only with cooperation of several persons, waste of manpower and material resources is caused, and engineering cost is high are solved. The invention further provides the normative construction method. The problems that in the prior art, construction specifications are relatively lacked, and construction methods are different and operation are not standard in current construction are solved. In addition, lifting installation performed on the buckling restrained supporting member can be finished under the condition of narrow spaces, and the problems that in the current construction, the chain blocks are applied with high requirements for spaces of construction environments, and adaptability to the narrow spaces of construction is not high are solved.

Description

technical field [0001] The invention belongs to the application field of building engineering construction, and in particular relates to a lifting installation system and a construction method of a buckling constrained support member. Background technique [0002] The buckling restrained support member is also called buckling-resistant support and unbonded support. It is improved on the basis of ordinary steel supports that are prone to buckling under pressure and have poor hysteretic energy dissipation capacity after buckling. It is a new type of support. Metal yield type damper. The working mechanism is to dissipate the energy of earthquake or wind vibration by using the core material with low yield point under axial compression and tension to dissipate the energy of earthquake or wind vibration. It is a kind of passive displacement related damper with better energy dissipation effect among all kinds of dampers used in buildings at present. It can be widely used in all ki...

Problems solved by technology

[0003] The main purpose of the present invention is to provide a lifting and installation system and construction method for buckling restrained support members, which solves the problems of relatively lack of construction specifications in the prior art, different construction methods in current construction, and irregular operations; at the same time, it solves the problems in the current construction The existing problems are that the progress is slow, many people need to cooperate with the construction to complete the construction, resulting in waste of manpower and material resources, and high project costs; in addition, it also solves the problem that the application of the chain-down in the current construction has high space requirements for the construction environment, and the construction space is relatively high. The problem of poor applicability in narrow situations
