Concrete filled steel tube row column shear wall with structural steel support and manufacturing method thereof

Abstract

The invention discloses a concrete filled steel tube row column shear wall with a structural steel support and a manufacturing method thereof. The shear wall comprises prefabricated concrete filled steel tubular columns arranged at certain intervals, structural steel supporting components, sleeve connecting components for connecting structural steel and concrete filled steel tubes, concrete poured into a wall space in a filling mode, and steel bar nets which are used for preventing early cracking of the concrete and arranged on two sides of a wall body in advance. The shear wall gives full play to the good axial compressive performance of the concrete filled steel tubular columns. The rigidity of the wall body is increased due to addition of the structural steel supporting components. A rubber pad layer is arranged in each sleeve connecting component, so that partial damage at the joints of the concrete filled steel tubular columns and the supporting components is reduced to a certain extent. Bulging of steel tubes is restrained due to the hooping function of sleeves to the concrete filled steel tubes, and the three layers of defenses including the concrete, the structural steel support and the concrete filled steel tubes are formed. The combined shear wall has high bearing capacity and a good anti-seismic property, most of the components are prefabricated components and are convenient to splice after being conveyed to a construction site, and work time is saved.

Description

technical field [0001] The invention relates to the technical field of building structures, in particular to a steel pipe concrete row column shear wall with steel support and a manufacturing method thereof. Background technique [0002] With the increasing height of super high-rise buildings and the continuous complexity of structural forms, the vertical load and horizontal load that the shear wall needs to bear are increasing. The anti-seismic ability needs to continuously increase the cross-section, resulting in problems such as self-heaviness and difficult construction. [0003] Steel and concrete composite shear walls can combine the advantages of the two materials to achieve high lateral stiffness, bearing capacity and good ductility. Among them, the steel plate-concrete composite shear wall is the most widely used, but the steel plate-concrete composite shear wall The vertical bearing capacity of the wall is low, and the out-of-plane buckling of the steel plate needs...

[0002] With the increasing height of super high-rise buildings and the continuous complexity of structural forms, the vertical load and horizontal load that the shear wall needs to bear are increasing. The anti-seismic ability needs to continuously increase the cross-section, resulting in problems such as self-heaviness and difficult construction

[0003] Steel and concrete composite shear walls can combine the advantages of the two materials to achieve high lateral stiffness, bearing capacity and good ductility. Among them, the steel plate-concrete composite shear wall is the most widely used, but the steel plate-concrete composite shear wall The vertical bearing capacity of the wall is low, and the out-of-plane buckling of the steel plate needs to be controlled during the transportation and installation process, which is relatively difficult; whether using cast-in-place concrete or prefabricated concrete slabs, fasteners need to be installed on site, which is inconvenient , the construction progress is delayed, and the transportation of precast concrete slabs is also extremely inconvenient. It is necessary to avoid cracking and damage of concrete slabs during transportation.

Moreover, after the damage of the shear wall, the whole panel needs to be replaced for maintenance, which is not economical.
