Construction method for pouring composite steel pipe column core concrete and composite steel pipe column

Abstract

The application discloses a construction method for concrete pouring of a composite column steel tube column core and a composite column steel tube column. It includes: opening a pouring hole on the side wall of the steel pipe column to match the pump pipe, and the position of the pouring hole is higher than the upper floor; installing the steel pipe column and building the upper floor, inserting the pump pipe into the pouring hole on the upper floor, Concrete is pumped to pour the lower steel pipe column core. The application also discloses a superimposed column steel pipe column. The workers in this application can work on the floor, which avoids the risk of high-altitude operations and tower cranes lifting the hopper at night, and reduces the impact of strong winds on the construction progress of the project, speeding up the construction progress; The steel pipe column core concrete, the wall column and the floor concrete are poured at the same time at the same time. The column core concrete does not need to use relatively high-cost high-throw vibration-free concrete, which not only ensures the construction quality, but also reduces the cost.

Description

technical field [0001] The present application relates to the field of building construction, and in particular to a construction method for concrete pouring of a composite steel pipe column core and a composite steel pipe column. Background technique [0002] In the design of super high-rise buildings, in order to reduce the size and weight of structural columns and increase the effective space and area, designers often design stiff steel pipes inside or on the surface of structural columns to increase the rigidity and strength of structural columns. But in the construction of this kind of rigid steel pipe laminated column, the pouring of the column core concrete has become a construction problem. [0003] In the prior art, the construction method of pouring steel pipe column core concrete adopts the construction method of high-throw vibration-free concrete pouring, that is, the method of manually hoisting the work platform by using a steel structure (or erecting the work p...

AI Technical Summary

Problems solved by technology

The high-altitude pouring cost of the high-throw vibration-free concrete pouring construction method is relatively high, and the existing technology has the intersection of steel structure hoisting and civil engineering reinforced concrete pouring procedures, and the construction progress of civil engineering restricts the construction progress of steel structures; moreover, this method is very easy. Affected by bad weather, construction cannot be carried out in strong winds or rainstorms. In order to improve the utilization rate of the tower crane and not directly affect the construction progress of the project, the project generally arranges night construction. There are great safety hazards such as falling from high altitudes, object strikes, and mechanical injuries.
