A construction method for concrete pouring in super high-rise steel pipe columns

Abstract

The invention discloses a super high-rise steel pipe column interior concrete pouring construction method. The method mainly comprises the steps of detaching a last section of steel pipe column top sealing hole thin steel plate; hoisting the present section of steel tube column; locating the present section of steel tube column after hoisting a first floor layer steel beam of the present section of steel tube column; arranging a detachable construction steel platform; enabling a sectional connectable serial barrel to extend into the steel pipe column through a locating hole of the construction steel platform; filling same-grade concrete protoplasmic into the steel pipe column; pouring concrete; when the concrete pouring height surpasses the single section serial barrel, detaching one section and continuing concrete pouring construction, and then conducting subsequent pouring; slowing down the speed of concrete discharging and the speed of pouring when a concrete puring face is close to a partition plate in the steel pipe column; pouring the concrete to a certain distance below the top of the steel pipe column and then stopping; adopting a thin steel plate to close the steel pipe column top pouring hole. By the adoption of the construction method, the concrete pouring construction is made to be more convenient, potential safety hazards are eliminated, the construction period is shortened, and manpower and turnover material consumption are reduced.

Description

technical field [0001] The invention belongs to the field of building construction, and in particular relates to a construction method for pouring concrete in a super high-rise steel pipe column. Background technique [0002] With the progress of society and the rapid development of urban construction, people pay more and more attention to the quality of life. In the architectural design stage, more and more steel structure systems are used in super high-rise structures, especially the frame column members are in the form of steel pipe columns to reduce the column cross-section and increase the building area, thereby reducing the overall cost of the project, while promoting green construction and environmental protection. . [0003] At this stage, the design has strict requirements for the construction of steel pipe columns in super high-rise buildings. After the construction of steel pipe columns reaches a certain number of floors, the concrete pouring in the steel pipe co...

Problems solved by technology

Combined with the steel structure construction process, under normal circumstances, after the steel columns and steel beams are installed in each construction section (generally three floors are one section), the floor slab construction will be carried out. If all steel beams and floor slabs in each construction section are constructed in sequence Then pouring the concrete inside the steel pipe column in this construction section will seriously restrict the progress of the project; if an operation platform is built from the bottom of each construction section, each steel pipe column with a height of nearly 10 meters needs to be erected. Occupied for a long time, it consumes a lot. Second, the construction progress is restricted by the process of erecting and dismantling the frame body, and the position occupied by the operating platform affects the construction work surface of the floor slab. Third, for the side column construction, the construction of the platform has certain construction difficulties , there is a large safety hazard; in addition, when pouring concrete in a steel pipe column nearly 10 meters high, it is necessary to control the quality control hidden dangers caused by unfavorable factors such as high height, relatively closed steel pipe column, and internal partitions.
