Continuous occlusion steel pipe concrete shear wall

Abstract

The invention discloses a continuous occlusion steel pipe concrete shear wall. The continuous occlusion steel pipe concrete shear wall comprises a steel pipe unit and an arc-shaped steel box unit, wherein the steel pipe unit is of a hollow cylindrical structure, and the interior of the steel pipe unit is used for pouring concrete; the arc-shaped steel box unit is defined by two stress side walls and two occlusion side walls, the two stress side walls are oppositely arranged, the two stress side walls are both of an arc surface structure, the two stress side walls protrude in the direction away from the center of the arc-shaped steel box unit, the two occlusion side walls are oppositely arranged, the two occlusion side walls are both of an arc surface structure, the two occlusion side walls protrude in the direction close to the center of the arc-shaped steel box unit, and the interior of the arc-shaped steel box unit is used for pouring concrete; and the side face of the steel pipe unit is fixedly connected with the occlusion side walls. According to the continuous occlusion steel pipe concrete shear wall, the steel pipe unit and the arc-shaped steel box unit are sequentially connected to jointly form the shear wall, the thickness of the shear wall is reduced, and the strength of the shear wall is improved.

Description

technical field [0001] The invention relates to the technical field of building structure engineering, in particular to a continuous occlusal steel pipe concrete shear wall. Background technique [0002] There are more and more super high-rise buildings, the height is getting higher and higher, and the thickness of the concrete shear wall of the core tube is getting thicker and thicker, which makes the actual utilization rate of the super high-rise building plane lower and lower, and the economy is also poor. At present, the common practice in the super high-rise core tube concrete shear wall is to add section steel, core steel pipe and other measures, but the actual effect of thinning the wall thickness is not obvious, and it increases the difficulty of construction, the construction cost is also greatly increased, and the construction quality is difficult to guarantee. . [0003] In addition, when it is necessary to make an arc-shaped shear wall with curvature, it is diff...

Problems solved by technology

[0002] There are more and more super high-rise buildings, the height is getting higher and higher, and the thickness of the concrete shear wall of the core tube is getting thicker and thicker, which makes the actual utilization rate of the super high-rise building plane lower and lower, and the economy is also poor

At present, the common practice in the super high-rise core tube concrete shear wall is to add section steel, core steel pipe and other measures, but the actual effect of thinning the wall thickness is not obvious, and it increases the difficulty of construction, the construction cost is also greatly increased, and the construction quality is difficult to guarantee.

[0003] In addition, when it is necessary to make an arc-shaped shear wall with curvature, it is difficult to use section steel or core for the core-tube concrete shear wall in the prior art where the arc curvature of the shear wall is relatively large. The steel pipe completely fills the part with larger arc curvature of the shear wall, which is the weak part where the stress concentration of the shear wall is, so when using the existing technology to construct the arc shear wall with curvature The body is prone to cracking, etc., which affects the beauty and safety of the building
