Construction method for assembled building cantilevered element

Abstract

The invention discloses a construction method for an assembled building cantilevered element, and belongs to the technical field of the assembled building. The construction method for the assembled building cantilevered element comprises the steps that the construction is prepared; the element is hoisted; a pendant-fitting is hanged, and the pendant-fitting is connected with the element; the elevation, verticality and levelness of the element is adjusted; a reserved steel bar of the element is fixed with a plate tendon; slab concrete is poured; and after the concrete reaches the design strength, the pendant-fitting is removed. The construction method for the assembled building cantilevered element is based on the steel mixing assembled structure system, without the need for using a traditional support system, the construction site is clean, neat, and unblocked, the construction period is short and the construction cost is low.

Description

technical field [0001] The invention belongs to the technical field of prefabricated buildings, in particular to a construction method for cantilevered components of prefabricated buildings. Background technique [0002] The mixed structure of steel structure and concrete is called steel-concrete hybrid structure. This structural form has the advantages of good seismic performance and strong integrity. [0003] In accordance with the requirements of promoting supply-side structural reform and new urbanization development, vigorously develop prefabricated buildings such as steel structures and concrete, which has multiple effects such as developing new energy-saving and environmental protection industries, improving building safety levels, and promoting the resolution of excess capacity. With the strong support of policy guidance, prefabricated buildings have gradually entered people's field of vision, and prefabricated buildings have lived up to everyone's expectations. Wit...

Problems solved by technology

[0004] At present, there are many problems in the vigorous development of prefabricated buildings. Among them, the prefabricated construction site is not as uniform, clean and environmentally friendly as expected. Among them, a large number of support systems are still required during the installation of prefabricated components of prefabricated buildings. Chaotic, especially the overhanging components of some prefabricated buildings combined with the traditional full frame support method, the construction site is still difficult for people to walk, and there is a big safety hazard

Of course, there is also an independent support system that came into being along with the prefabricated building, which makes the whole construction site much cleaner and fresher, but a large number of triangular supports also make it very inconvenient to inspect and check in and out of the construction site, and safety accidents often occur

[0005] In addition, the installation process of the prefabricated cantilever components of the existing prefabricated buildings is usually constructed gradually from the ground floor to the top floor of the building, which also leads to a long construction period.
