Embodiment Construction

[0053] Examples see Figure 5 , Image 6 As shown, a prefabricated T-shaped mixed limb wall includes a first wall unit 1 and a second wall unit 2 that are vertically connected together to form a T shape, and the first wall unit 1 and the second wall unit 2 All are prefabricated components, the concrete strength grade is not less than C30 and not higher than C60, and the two are connected by joint post-casting belt 3; the joint short beam 1.5 of the first wall unit and the joint short beam of the second wall unit 2.5 The two are butted and poured inside the joint post-casting belt 3, and the joint post-casting belt 3 is also equipped with a vertical reinforcement bar 3.1 and a joint placed outside the joint post-casting belt vertical reinforcement 3.1. Stirrup bars 3.2 are cast after the seam, and when the vertical reinforcement 3.1 with the post-cast joint is two rows, the vertical reinforcement 3.1 with the post-cast joint is placed on the joint short beam 1.5 of the first w...

Abstract

An assembled T-shaped mixed limb wall and its construction method. The assembled T-shaped mixed limb wall includes a first wall unit and a second wall unit that are vertically connected to each other and form a T shape. The first wall unit and the second wall unit The two wall units are all prefabricated components, and the two are connected by post-cast joints. 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 and a lot of construction waste on the construction site, which is convenient to meet the requirements of building use and simplifies the assembly process; after butt welding of short beams at seams, a relatively large rigidity has been formed between the wall units, which is conducive to the construction of the wall during the construction process. The stability of the structure saves the process of prefabricated shear walls as temporary support, ensuring 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...
