Problems solved by technology

[0004] The purpose of the present invention is to address the existing cast-in-place structure and the traditional assembled integral shear wall structure that require on-site wet work, a large amount of engineering, difficult construction quality, and large damage to the structure after the earthquake and large residual deformation of the structure. Due to the high cost or irreparable deficiencies, this application proposes a vertical prestressed assembled energy-dissipating joint wall structure and its assembly method to solve the above technical problems

Embodiment 1

[0053] This embodiment 1 proposes a vertical prestressed assembled energy-dissipating combined limb wall structure, the main structure of which mainly includes vertical segmental prefabricated wall limb assemblies 100, reinforced concrete connecting beams 200, vertical unbonded prestressed tendons 300 , prestressed steel rod 400 , energy-dissipating connection joint assembly 500 at the end of the connecting beam, and energy-dissipating connection joint 600 at the vertical wall pier.

[0054] When setting, the top and bottom elevations of the vertical section prefabricated wall pier assembly 100 are respectively located at the floor elevation. Among them, the vertical section prefabricated wall pier assembly 100 includes the bottom vertical section prefabricated wall pier 101 and several adjoining layer vertical section prefabricated wall pier 102, the bottom vertical section prefabricated wall pier 101 and the adjoining layer vertical section A row of vertical prestressed tend...

Embodiment 2

[0066] Embodiment 2 discloses a method for assembling a vertically prestressed energy-dissipating joint wall structure, including the following steps:

[0067] Step 1: The prefabricated wall plinth 101 of the foundation and the vertical section of the bottom layer is cast-in-place;

[0068] Step 2: pre-embed the vertical unbonded prestressed tendons 300 at the bottom of the foundation and pass through the vertical prestressed tendon holes 103 on the prefabricated wall pier 101 of the bottom vertical section;

[0069] Step 3: Lay ultra-high-performance concrete mortar cushion 104 on the upper part of the prefabricated wall plinth 101 of the vertical section of the bottom layer, and then place the prefabricated wall pier 102 of the vertical section of the adjoining layer in place, and vertically unbonded prestressed tendons 300 Pass through the vertical prestressing tendon hole 103 reserved on the prefabricated wall pier 102 of the vertical section of the adjoining layer, and in...

Abstract

The invention relates to the technical field of construction, and specifically discloses a vertical prestressed assembled energy-consuming joint wall structure and an assembly method thereof, comprising a vertical segment prefabricated wall assembly, a reinforced concrete connecting beam, a vertical unbonded prefab Stress tendons, prestressed steel rods, coupling beam end energy dissipation connection joint assemblies and vertical wall pier energy dissipation connection joints, the vertical segment prefabricated wall pier assembly includes a bottom vertical segment prefabricated wall pier and several The vertical segment prefabricated wall pier of the addition layer, the vertical energy dissipation wall pier energy dissipation connection joint includes a plurality of first energy dissipation pads arranged on the front and rear sides of the wall pier and second energy dissipation pads arranged on the left and right ends of the wall pier The lifting and connecting limb wall structure of the present invention does not require on-site wet operation, belongs to dry connection, and uses the rebound effect of the vertical prestressed tendons to reset the structure after the earthquake, the residual deformation is small, and the damage is concentrated at the node connection. It is mainly concentrated on replaceable energy-consuming components, and the post-earthquake repair is simple and quick, which can realize the rapid recovery of structural functions after the earthquake.

Description

technical field [0001] The invention relates to the technical field of buildings, and specifically discloses a vertically prestressed assembled energy-dissipating joint wall structure and an assembly method thereof. Background technique [0002] Both the cast-in-place structure and the traditional assembled integral shear wall structure, the two traditional shear wall structures, require on-site wet work, the structure of the wall and connecting beam reinforcement is complex, the site engineering is large, and the construction quality is difficult to guarantee. In addition, these two shear wall structures dissipate seismic energy through ductile damage under the action of a large earthquake. The damage and residual deformation of the structure after the earthquake are large, and the repair cost is high or cannot be repaired. The structure can only be demolished and rebuilt, resulting in Huge waste. [0003] For example, the invention patent with the application number CN200...
