Problems solved by technology

[0004] The present invention mainly solves technical problems such as difficult calculation of additional internal force, complex construction, high cost and other technical problems caused by the difference in vertical deformation at both ends of the "hard-resistant" coupling beam in the prior art, and proposes a construction of coupling beams between shear wall limbs The method, installation structure and combined structure can release the additional internal force generated by the different vertical settlement at both ends of the coupling beam, reduce the cross-sectional size of the coupling beam, and reduce the steel content of the coupling beam

Abstract

The invention relates to the field of constructional engineering and provides a construction method, a mounting structure and a combined structure for a coupling beam between shear wall limbs. The construction method includes: burying anchor bolts in a shear wall limb on one side; fixing a steel support frame on the shear wall limb with the anchor bolt via anchor bolts and nuts; above the steel support frame, constructing stirrups and longitudinal reinforcement steel bars of the coupling beam; pouring concrete of the coupling beam to enable one end of the poured section of the coupling beam to be mounted on the shear wall limb without the steel support frame, enable the other end of the poured section of the coupling beam to overlap on the steel support frame and reverse a vertical seam between the poured section of the coupling beam and the shear wall limb with the steel support frame; after vertical differential settlement between each of two ends of the poured section of the coupling beam and the corresponding shear wall limb is smaller than 2-4mm, pouring concrete to the vertical seam to form an integral coupling beam. The construction method, the mounting structure and the combined structure have the advantages that additional internal force generated from vertical deformation difference between two ends of the coupling beam can be released, section size of the coupling beam can be decreased, and steel content of the coupling beam is decreased.

Description

technical field [0001] The invention relates to the field of construction engineering, in particular to a construction method, an installation structure and a combined structure of a connecting beam between limbs of a shear wall. Background technique [0002] At present, due to the diversification, individuation, and complexity of architectural design, in order to meet the building function and use requirements, the distance between two shear walls is often very close during structural design, and the vertical loads borne by these two shear walls are different. It is very large, so that the vertical deformation of the two shear wall piers under the vertical load is quite different, so the vertical deformation of the two ends of the connecting beams connecting the two shear walls is quite different, resulting in the connection Beams generate large additional internal forces. In order to meet the stability and rigidity requirements of the entire structure, the two ends of the...
