Abstract

The invention provides a construction method of an outrigger truss structure in order to release additional stress of the outrigger truss, solve the problem that the outrigger truss cannot be fixedlyconnected in time in the construction process of a building overall structure, eliminate the influence of the outrigger truss on the construction procedures and improve the construction efficiency. The construction method of the outrigger truss structure is used for connecting an outer frame column structure and a core tube structure. When stress is generated between different building structuresdue to differential deformation, vertical sliding devices used for one-way control over displacement can make the two sides of the outrigger truss structure slide mutually, so that the stress is released, and the construction quality is guaranteed.

Description

technical field [0001] The invention belongs to the technical field of building engineering construction, and in particular relates to a construction method of an outrigger truss structure. Background technique [0002] The continuous increase in the height of the building structure will lead to problems such as the decrease of the lateral stiffness of the overall structure of the building and the lengthening of the basic period of the structure. Under the action of lateral force, the lateral displacement of the structure increases, and the bottom of the structure is subjected to different degrees of tension, which intensifies the P-Δ effect of the structure. [0003] After years of research and practice, the engineering community has successfully adopted the method of setting horizontal outrigger reinforcement layers to increase the lateral stiffness of the structure to control the lateral displacement of the structure. The principle of the outrigger truss is to coordinate...
