Corbel column concrete construction method

Abstract

The invention discloses a cow-leg post concrete construction method. The method comprises the step of arranging a cow-leg post template on a construction foundation. The step of arranging the cow-leg post template comprises the following steps of forming a notch which extends downwards in the top of the cow-leg post template when the cow-leg post template is mounted, wherein the height of the template below the notch is respectively three times of concrete casting heights, forming a plurality of slurry outlets at intervals along the peripheral direction in the cow-leg post template according to each time of concrete casting height; while filling concrete into the template, vibrating the concrete through the notch; after initial set and before final set of each layer of concrete, using pressure water to flush and clean a construction seam through the notch; finally, coating a layer of concrete curing plastic film on the surface of the third concrete after initial set of the third concrete until the curing period ends. A layered casting method is adopted, so that the phenomenon that the concrete is not compact after the concrete is vibrated when the reinforcement ratio is too high is avoided, the phenomenon that the concrete is cracked when a large-size cow-leg is casted is also avoided, the concrete construction quality is improved, the construction difficulty is reduced, and construction is more convenient to perform.

Description

technical field [0001] The invention relates to the field of building construction, in particular to a corbel concrete construction method. Background technique [0002] The so-called corbel is a small platform structure on the column, on which horizontal structural beams can be placed, and the column with such a corbel is called a corbel column. Corbel columns are generally used in reinforced concrete structures, and transverse beams are placed on the corbels of the columns and combined with other columns and beams to form a building structure. The corbel column is an integral component under transverse tension and oblique compression inside, and its three-way reinforcement is more complicated and dense compared with column beam components. In addition, the embedded parts on the corbel column are accurately positioned, and its concrete construction requires one-time construction. Construction joints shall not be reserved for permanent pouring, and the positions of steel ba...

AI Technical Summary

Problems solved by technology

For corbel columns with oblique ring beams, tension beams, inter-column supports and multiple embedded parts, the overall space is limited, the diameter of steel bars is large, and the number of interspersed steel bars is large; and the size of steel embedded parts in corbel columns Large, complex anchor foot design, interspersed with multiple components

In addition, the corbels are large in size, the weight of the concrete is too large, and the concentrated load is too large. If the pouring is completed at one time, it is easy to cause cracking of the concrete. At the same time, the reinforcement is too dense, and the vibration is not easy to reach, resulting in voids inside the corbel. Exterior honeycomb numbness, exposed tendons, etc.
