Prefabricated reinforced concrete shear wall and construction method

Abstract

The invention discloses a prefabricated reinforced concrete shear wall and a construction method. The prefabricated reinforced concrete shear wall comprises a concrete wall body, wherein an edge member is arranged at one side of the concrete wall body, horizontal protruding longitudinal bars are arranged at the other side of the concrete wall body, vertical protruding longitudinal bars are arranged at the two sides of the concrete wall body, and steel beam adapting pieces are arranged at the two ends of the edge member. The construction method comprises the steps of 1, suspending the prefabricated reinforced concrete shear walls at the same layer to a specified position; 2, bundling up stirrups and longitudinal bars in a horizontal connecting area to obtain a lower-layer shear wall framework; 3, suspending two prefabricated reinforced concrete shear walls at the upper layer; 4, arranging hidden beam reinforcing steel bars and hidden beam longitudinal bars in a vertical connecting area;5, connecting and fixing the steel beam adapting pieces which are adjacent up and down, arranging longitudinal bar connectors among embedded column longitudinal bars, making the stirrups penetrate through stirrup holes; 6, setting up a concrete pouring formwork; and 7, conducting concrete pouring and forming to obtain a wall body of the current layer. The prefabricated reinforced concrete shear wall simultaneously has the advantages of low construction cost, convenience in connection and good fireproof performance.

Description

technical field [0001] The invention relates to a shear wall, in particular to a prefabricated reinforced concrete shear wall and a construction method. Background technique [0002] Shear walls are also known as seismic walls or structural walls; walls that mainly bear horizontal and vertical loads caused by wind loads or earthquakes in houses or structures. The existing traditional shear walls are mainly reinforced concrete structures, which are generally made of cast-in-place concrete. It needs to bind the steel skeleton and pour concrete on site. Not only is the construction speed slow, but it is also difficult to ensure the pouring quality; secondly, concrete beams The self-weight is relatively heavy, which affects the cost of vertical components and foundations, and the seismic performance of the structure is not high. Under the same span and load conditions, the beam height of the concrete beam is relatively high, which reduces the clear height of the building and aff...

AI Technical Summary

Problems solved by technology

The existing prefabricated shear wall structure system is mainly a steel plate composite shear wall, which is convenient to connect, fast in construction, and has guaranteed construction quality; however, the fire performance of the steel composite shear wall is poor, and additional fire protection is required, and the cost is relatively high. High, fireproof materials also occupy the usable area of ​​the building, resulting in inefficient use of the building

Fireproof materials are easily destroyed in the later decoration project, which affects the fireproof safety of the structure; at the same time, the steel consumption is high and the cost is high

Therefore, the existing technology has the problem of being unable to take into account low cost, convenient connection and good fire performance at the same time.
