Installation and construction method for reinforcing steel bars in core area of beam-column joint

Abstract

The invention discloses a beam column joint core area reinforcing steel bar installation construction method which comprises the following steps that stirrups in the range from the bottom of a beam column to a plate face are reserved and not installed, and the stirrups which should be originally installed in a beam column core area are reversely arranged above the plate face and fixed to column main reinforcements; arranging an electric welder to weld four sides of each upturned stirrup by using a steel bar head with the same beam height; after beam steel bars are bound, the uppermost set of stirrups fixed to column main bars are unfastened, meanwhile, the erected beam steel bar support is loosened, the whole beam steel bars fall to a beam bottom column, a core hoop is also installed in place, and the stirrup binding quality in a beam column core area is guaranteed; the beam bottom bar binding quality at the beam column joint is ensured; and the working efficiency is improved, the working efficiency of woodworking is improved, and good technical support is provided for promoting the engineering construction progress.

Description

technical field [0001] The invention relates to the technical field of building construction, in particular to a method for installing steel bars in the core area of ​​beam-column joints. Background technique [0002] With the continuous emergence of various new structural forms in my country's architectural field, the methods of structural design have gradually become diversified. From the design point of view, it is necessary to ensure the "safety and firmness" of the physical structure and the "functional use, beautiful appearance and exquisiteness" of the formed building. With the continuous development of my country's construction industry, large-scale commercial complex projects need The expectations of users are also constantly increasing, that is to say, on the premise of meeting the "limit state of bearing capacity", users have a deeper understanding and requirements for the "limit state of normal use" of the building. The beam and column components of the frame str...

Problems solved by technology

[0003] As we all know, there are many steel bars in the core area of ​​the beam-column joint, and there has always been the problem of binding difficulties. In the conventional method, the beam bottom bars at the beam-column junction require carpenters to leave beam side plates to ensure the quality of the beam bottom steel bar binding. The traditional method is time-consuming and laborious. The quality of steel bar binding cannot be guaranteed, and the installation progress is relatively long
