Technical Field
The utility model relates to a building field especially relates to a novel low shear wall structure of embedded PVC pipe reinforced concrete.
Background
In order to meet the multifunctional use requirements of buildings, high-rise buildings with large spaces at the bottom are more and more widely applied to urban construction. Due to the limitation of the height of the structural layer and the relatively large opening and depth of the underlying frame, the aspect ratio of the shear wall in this case is generally less than 1, forming a so-called low shear wall. According to the survey results of earthquake damage of the past and a large number of experimental researches, the low shear wall mainly takes shear deformation as main, brittle failure occurs, the member is not obviously damaged, the earthquake-resistant performance is poor, the existing structural technology does not meet the earthquake-resistant requirement of the building or influences the building attractiveness after the building is built, and the low shear wall cannot be popularized to the majority of buildings. Therefore, engineering technicians need a novel embedded PVC pipe reinforced concrete low shear wall structure, and the earthquake resistance of the low shear wall at the bottom of a building is improved on the premise of ensuring the neat appearance of the building.
SUMMERY OF THE UTILITY MODEL
An object of the utility model is to prior art's defect with not enough, provide a novel low shear wall structure of buried PVC pipe reinforced concrete, under the clean and tidy prerequisite of assurance building outward appearance, improve the anti-seismic performance of the low shear wall of building bottom.
In order to realize the technical purpose, the utility model discloses a technical scheme is: a novel embedded PVC pipe reinforced concrete low shear wall structure comprises a ground beam, a frame beam, a shear wall and PVC pipes; the shear wall is arranged between the ground beam and the frame beam, and PVC pipes are arranged inside the shear wall to form an integral anti-seismic shear wall structure with the PVC pipes embedded inside; the ground beam is a building foundation beam and is used as a building bottom layer stress member; the frame beam is a bearing component of the upper structure of the building; the shear wall comprises a concrete layer and a reinforcing steel layer, wherein the reinforcing steel layer is uniformly arranged from a ground beam to a frame beam according to building specifications, is arranged along the arrangement direction of the shear wall, and reserves a PVC pipe installation embedding position; the PVC pipe is a PVC environment-friendly circular pipe, is uniformly arranged among the steel bar layers, and is provided with reinforcing steel bars at two sides so as to ensure the shearing resistance of the PVC pipe; after the PVC pipes are arranged, sealing ports at two ends of the PVC pipes, and pouring to form a concrete layer to form an integral shear wall structure; holes are reserved at two ends of the PVC pipe, penetrate through the reinforcing steel bars and are bound and fixed with the stressed reinforcing steel bars on the reinforcing steel bar layer, and the anti-floating effect of the PVC pipe in the concrete layer pouring process is guaranteed.
Preferably, the thickness of the shear wall is set to be 200 mm.
Preferably, the arrangement distance of the PVC pipes inside the shear wall is 400 mm.
The utility model has the advantages that: the utility model can convert the common low shear wall into a plurality of wall columns with the height-width ratio larger than 1, which is characterized in that the low shear wall is converted into the bending damage of each wall limb unit from the integral shearing damage, the strength of the material is fully utilized, and the energy consumption capability of the low shear wall is improved; on the premise of not influencing the appearance of the building, the anti-seismic performance of the building shear wall can be effectively improved.
