Description
Technical field
The present invention relates to a kind of pouring procedure of coupled shear wall structure, belong to building engineering field.
Background technology
Shear wall structure (shearwall structure) replaces the beam column in the frame construction with reinforced concrete wall panel; Can bear the internal force that all kinds of loads cause; And the effective horizontal force of control structure, this structure of bearing vertical and horizontal force with reinforced concrete wall panel is called shear wall structure.It is the bearing system that a kind of reinforced concrete wall constitutes.The anti-side rigidity of shear wall structure is bigger, and the distortion of generation is the flexure type distortion basically.This kind distortion is caused that by normal stress one side is drawn a side pressurized (the anti-side rigidity of frame construction is less, and stratified deformation rises with floor height and reduces, and the distortion of generation is the shearing-type distortion basically, is caused by shear stress) during distortion.At present, shear wall structure is widely used in building engineering.Along with improving constantly of social production force level, the popularization and application of commercial concrete and pumping of concrete technology, concrete poring rate has had large increase, has also promoted the fast development of shear wall structure.
The pouring procedure of existing coupled shear wall structure generally is a cast-in-situ steel reinforced concrete; Promptly at the construction field (site) reinforcing bar both sides are assembled row's common templates respectively; Placing of concrete is starched between two row's common templates again; After waiting to solidify, remove the common templates of both sides, get final product so that concrete grout is floating in surface of wall again.Yet there is following problem in above-mentioned pouring procedure: the engineering time of (1) said method is longer, must increase cost, and receives weather conditions and to influence the chance of construction period higher; (2) traditional template generally is wooden form or steel form, and wooden form has expended a large amount of forest reserves in producing use, and recovery utilization rate is low, has expended a large amount of material resources manpowers, and the environment to China has caused serious harm simultaneously; And traditional steel form exist from great, repeat usage is low, dismounting is difficult, operator's labour intensity is big, and problem such as construction quality is not high.
Therefore, develop a kind of pouring procedure of new coupled shear wall structure,, have active operation significance to improve efficiency of construction and construction quality.
