Problems solved by technology

[0004] The object of the present invention is to provide a construction method for deep connecting beams with built-in diagonal steel trusses in laminated shear walls with openings. The structural steel truss of the laminated wall piece bears the new role of the internal force of the structure, so that the laminated deep connecting beam can meet the structural force and seismic requirements without adding additional reinforcement, which is in line with the "strong shear weak bending" of deep connecting beams The principle of ductility design and effectively solve the problem of difficult reinforcement arrangement in the construction process

Abstract

The invention relates to a construction method for a composite shear wall with an opening and a built-in diagonal steel truss deep connecting beam, which comprises the following steps: a prefabricated processing plant manufactures a prefabricated composite shear wall, which is used to manufacture the overall reinforced skeleton of the composite shear wall , two obliquely arranged steel bar trusses are placed crosswise between the longitudinally stressed steel bars of the coupling beams, and then the steel bar skeletons of the coupling beams are effectively connected with the steel mesh pieces in the prefabricated wall panels of the inner and outer leaves, and finally the concrete of the wall panels is poured to form a prefabricated Composite shear wall: transport the prepared prefabricated composite shear wall to the construction site, pour the core concrete and wait for the core concrete to reach a certain strength, then carry out the construction of the superstructure to complete the construction of the entire shear wall structure. The present invention utilizes obliquely arranged steel bar trusses to improve the shear resistance of the laminated deep connecting beams, endows the structural steel bar trusses connected to the laminated wall pieces with a new function of bearing structural internal forces, and makes the laminated deep connecting beams without additional reinforcement Under the circumstances, it can meet the structural force and seismic requirements.

Description

technical field [0001] The invention relates to the technical field of building engineering construction, in particular to a construction method for a deep connecting beam with a built-in diagonal steel bar truss in a superimposed shear wall with an opening. Background technique [0002] As an important part of the shear wall structure system, the coupling beam has a decisive influence on the seismic performance of the structure. In the frame-shear wall structure and frame-core tube structure, since the shear wall and the core tube bear most of the horizontal load, when necessary, it is advisable to select coupling beams with a small span-to-height ratio (for example, less than 2.5) to ensure that the structure In other cases, it is also possible to choose a coupling beam with a smaller span-to-height ratio due to structural reasons. Due to the relatively small shear-bending ratio of this type of coupling beam, if the section design and reinforcement method of conventional ...
