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

Abstract

A prefabricated steel beam joint L-shaped mixed limb wall and its construction method, the fabricated steel beam joint L-shaped mixed limb wall includes a first wall unit and a second wall that are vertically connected together to form an L shape The units, the first wall unit and the second wall unit are all prefabricated components, and the two are connected by joint post-casting tapes. The present invention uses steel beams instead of concrete beams, and steel columns instead of edge-constrained reinforced concrete concealed columns, so that the hybrid connected limb wall has better energy consumption capacity and continuous collapse resistance than the traditional connected limb wall, and the factory prefabrication and on-site installation can be carried out at the same time. It solves the problems of large amount of wet work on the construction site and a lot of construction waste, and simplifies the assembly process; after butt welding of the short joints, the wall units have formed a relatively large rigidity, which is conducive to the stability of the wall during the construction process, eliminating the need for The process of prefabricated shear walls as temporary support ensures 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...
