Column-plate-concrete combined shear wall and construction method thereof

Abstract

The invention discloses a column-plate-concrete combined shear wall. The column-plate-concrete combined shear wall comprises steel stand columns, steel forms, connecting fasteners and cast-in-place concrete layers, wherein the steel stand columns comprise flange units, the connecting fasteners are fixed to the steel forms and can be fastened to the flange units of the steel stand columns in the length direction of the steel stand columns, and every connecting fastener is composed of a fastening unit and an expanding unit; the steel forms are composed of internal forms and outer forms, betweenwhich the cast-in-place concrete layers are arranged. The column-plate-concrete combined shear wall has the advantages that good quality stability and high production efficiency are achieved; the steel stand columns provide out-of-plane support force for assembly of the steel forms to save support during assembly of the steel forms, improve the construction efficiency and reduce construction procedures; the steel stand columns arranged on the left and right of the column-plate-concrete combined shear wall can ensure reliable connection between the column-plate-concrete combined shear wall between a neighboring steel beam; the steel forms and the steel stand columns are combined into the formwork of the cast-in-place concrete layers and serve as the permanent stress components of the skeleton of the column-plate-concrete combined shear wall, and the steel forms and the steel stand columns are combined and connected in a fastening manner to achieve high construction efficiency and reliable connection.

Description

technical field [0001] The invention relates to a column-slab concrete combined shear wall and a construction method thereof. Background technique [0002] Shear walls, also known as wind-resistant walls, earthquake-resistant walls or structural walls, are walls in houses or structures that mainly bear the horizontal loads caused by wind loads or earthquakes, and prevent structural shear (shear) damage. According to the structural materials, shear walls can be divided into steel plate shear walls, reinforced concrete shear walls and reinforced block shear walls. Among them, reinforced concrete shear walls are the most commonly used. Reinforced concrete shear walls are heavy, the cast-in-place construction procedures are cumbersome, and construction efficiency is low; prefabricated production, transportation and installation costs are high, and the reliability of on-site installation and connection of prefabricated concrete shear walls is poor.

Problems solved by technology

Reinforced concrete shear walls are heavy, and the cast-in-place construction procedures are cumbersome and construction efficiency is low; prefabricated production, transportation and installation costs are high, and the reliability of on-site installation and connection of prefabricated concrete shear walls is poor

[0003] Steel plate shear walls can be divided into single steel plate shear walls and double steel plate shear walls. Single steel plate shear walls need on-site formwork and steel bar binding. The construction process is cumbersome and the construction efficiency is low. It is not suitable for industrial production and assembly construction; The steel plate shear wall needs to be temporarily supported on site. At the same time, if the double steel plate is prefabricated in the factory, the weight of the single piece is relatively heavy. If it is combined on site, it needs to be connected by welding or bolts. It is difficult to set up the connection nodes between the double steel plate shear wall and the adjacent steel beam, and the reliability is difficult to guarantee
