Problems solved by technology

[0005] The purpose of the present invention is to propose a reinforced concrete shear wall with built-in positioning prefabricated parts for the existing reinforced concrete shear wall and its construction methods, such as poor positioning of steel bars, inaccurate thickness of the protective layer, and easy formwork bulging of the formwork. and construction methods, in the construction of reinforced concrete shear walls, vertical ladder bars and horizontal ladder bars are used as the positioning support frame for the binding of steel bars, and the positioning prefabricated parts are clamped into the horizontal and vertical distribution bars to ensure the thickness of the protective layer and strengthen the steel mesh at the same time Assembled steel formwork is installed on both sides of the steel mesh piece, and the tensioning screw is passed through the connecting steel pipe and fastened by bolts. The diagonal brace of the steel formwork is connected to the embedded part of the floor structure, and finally concrete is poured to form a shear wall structure.

Abstract

The invention relates to a reinforced concrete shear wall with a positioning prefabricated member inside and a construction method of the reinforced concrete shear wall. The construction method includes: manufacturing the prefabricated member; arranging the prefabricated member on a floor slab structure; making positioning ladder rebars; binding rebars; mounting the prefabricated member; mounting steel formworks; setting up a steel formwork inclined strut. During constructing the reinforced concrete shear wall, vertical ladder rebars and horizontal ladder rebars are adopted as a positioning supporting frame for rebar binding, and the positioning prefabricated member is clamped in horizontally-vertically-distributed rebars, so that thickness of a protection layer is guaranteed and connection of rebar nets is enhanced; the assembly steel formworks are arranged on two sides of the rebar nets, oppositely-puling threaded rods penetrate connecting steel pipes to be fastened on embedded members of the steel formwork inclined strut and the floor slab structure through screws, and concrete is poured to form a shear wall structure. By using the construction method, construction site order and construction efficiency are improved, related measures guarantee construction quality of the shear wall, rebar positioning accuracy and thickness accuracy of the protection layer are improved remarkably, and the construction method has good technical and economic benefit.

Description

technical field [0001] The invention relates to a reinforced concrete shear wall with a built-in positioning prefabricated part and a construction method thereof, which is suitable for the construction of a reinforced concrete shear wall in frame shear wall structures of industrial and civil buildings. Background technique [0002] The anti-seismic fortification of buildings is the first line of defense to ensure the safety of people's lives and properties. Since the Wenchuan earthquake, the "Code for Seismic Design of Buildings" (GB50011-2010) has improved the anti-seismic fortification intensity of buildings in earthquake-prone areas. Increase the seismic level accordingly. Engineering practice shows that the frame-shear wall structure of high-rise buildings has excellent seismic performance, and the shear wall structure can provide strong horizontal force resistance when an earthquake occurs, thereby ensuring the safety of the building. [0003] The construction quality ...
