Problems solved by technology

The existing pouring process of concrete frame columns is: binding steel bars - building formwork - wetting - pouring - vibrating. The concrete frame columns manufactured by this conventional method often have rotten roots, and the pass rate is only about 50%. Concrete frame columns must be poured again, seriously affecting construction efficiency and cost

Embodiment Construction

[0028] When using the existing conventional construction technology, there are a large number of concrete frame columns with rotten roots. The applicant carefully studied the reasons for the rotten roots and found that most of the concrete frame columns with rotten roots existed in the pouring cavity before pouring. A small amount of stagnant water, stagnant water is produced during the wetting process, and wetting refers to watering the inside of the formwork and the steel bars, so as to keep the inside of the formwork and the steel bars in a wet state, so as to prevent the formwork and steel bars from absorbing water when pouring concrete. The existing formwork encloses a sealed pouring cavity, and excess water flows to the bottom of the pouring cavity and generates accumulated water, which causes rotten roots of the concrete frame columns after pouring, affecting the load-bearing capacity. In response to this phenomenon, the applicant made improvements to the prior art.

Abstract

The invention provides a pouring method of a high and large concrete frame column. The pouring method comprises the steps that a steel bar cage is formed by binding column steel bars, a plurality of vibrating holes are formed in the edge of the steel bar cage, and a pouring hole is formed in the central position of the steel bar cage; templates are arranged around the steel bar cage in a supportedmode, and drainage outlets are correspondingly formed in the bottoms of the templates; the templates and the steel bar cage are watered, so that the templates and the steel bar cage are wet, and thesurplus water flows to the bottom of a pouring cavity and is discharged from the drainage outlets; the drainage outlets are blocked; a layer of mortar is poured at the bottom of the pouring cavity; concrete is gradually injected into the pouring cavity by using a feeding guide pipe, and a concrete column is obtained; and the concrete column is vibrated. By forming the drainage outlets, the surpluswater can be quickly discharged from the drainage outlets, thus the concrete frame column root rot caused by ponding at the bottom of the pouring cavity is prevented, and the strength and bearing capacity of the concrete frame column are ensured; and in addition, by improving the vibration technology, the concrete can be vibrated quickly, holes in the concrete frame column are prevented, and theconstruction quality is ensured.

Description

technical field [0001] The invention relates to the technical field of building construction, in particular to a pouring method for tall concrete frame columns. Background technique [0002] Tall reinforced concrete frame column refers to a reinforced concrete frame column with a height greater than 8 meters. It is a commonly used supporting column in a factory building. It plays a load-bearing role. Defects such as pockmarks and holes. The existing pouring process of concrete frame columns is: binding steel bars - building formwork - wetting - pouring - vibrating. The concrete frame columns manufactured by this conventional method often have rotten roots, and the pass rate is only about 50%. Concrete frame columns must be poured again, seriously affecting construction efficiency and cost. Contents of the invention [0003] The technical problem to be solved by the present invention is to provide a concrete frame column pouring method, which can prevent root rot at the b...
