Prefabricated steel beam joint cross-shaped mixed limb wall and its construction method

Abstract

An assembled steel beam joint cross-shaped mixed limb wall and its construction method, the assembled steel beam joint cross-shaped mixed limb wall includes a first wall unit and a second wall unit that are vertically connected to each other to form a cross shape, wherein The first wall unit is symmetrically distributed on both sides of the second wall unit, both of the first wall unit and the second wall unit are prefabricated components, and the two are connected by joint post-casting strips. The invention uses shaped steel columns instead of edge-constrained reinforced concrete concealed columns, so that the mixed limb wall has better energy consumption capacity and continuous collapse resistance than the traditional limb wall, and the factory prefabrication and on-site installation are carried out at the same time, which solves the problem of wet operation on the construction site The assembly process is simplified due to the problems of large quantity and construction waste; after butt welding of the short beams at the joints, a relatively large rigidity has been formed between the wall units, which is conducive to the stability of the wall during the construction process, eliminating the need for prefabricated shear walls as temporary supports The process ensures the construction efficiency. It can be widely used in the construction of mixed limb walls in construction projects.

Description

technical field [0001] The invention relates to a connected limb wall for construction engineering and a construction method thereof, in particular to an assembled mixed limb wall and a construction method thereof. Background technique [0002] The high-rise building structure is an inevitable choice to solve the contradiction between the growing urban population and the gradual shortage of urban land in the process of urbanization in my country, and the connected wall structure system is an indispensable element in the high-rise building structure. According to previous measured data, the attached wall system not only inherits the advantages of simple shear wall engineering, such as low cost and high lateral stiffness, but also reflects the yield energy consumption of the connecting beam under the action of strong earthquakes, and reduces the concentration of a large number of cracks at the bottom of the wall. , to reduce the cost of post-earthquake repairs. However, in th...
