Assembly-type steel beam joint cross-shaped mixed coupled wall and construction method thereof

Abstract

Disclosed are an assembly-type steel beam joint cross-shaped mixed coupled wall and a construction method thereof. The assembly-type steel beam joint cross-shaped mixed coupled wall comprises first wall units and a second wall unit which are connected together perpendicularly and form a cross shape. The first wall units are symmetrically distributed on the two sides of the second wall unit, the first wall units and the second wall unit are all prefabricated parts, and the first wall units and the second wall unit are connected through joint post-pouring belts. According to the assembly-type steel beam joint cross-shaped mixed coupled wall, steel beams are used for replacing concrete beams and section steel columns are used for replacing edge constraint reinforced concrete embedded columns, so that the mixed coupled wall has better energy-dissipating capacity and progressive-collapse-resistant capacity than a traditional coupled wall; prefabrication and on-site installation are conducted at the same time, therefore, the problems that the quantity of wet construction on a construction site is large and a lot of construction waste is generated are solved and assembly procedures are simplified; after butt welding is conducted on joint short beams, high rigidity is formed between the wall units, therefore, the stability of wall bodies in the construction process is facilitated, the procedure that a shear wall is prefabricated to be used as a temporary support is omitted and the construction efficiency is guaranteed. The construction method can be widely applied to construction of mixed coupled walls in constructional engineering.

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...
