Construction method for self-compaction of constructional column concrete

Abstract

The invention discloses a construction method for self-compaction of constructional column concrete. The construction method comprises the following steps: (1) designing a concrete mix proportion; (2)designing a formwork; (3) mounting the formwork; (4) pumping and jacking concrete; (5) closing a check valve when full jacking is achieved; and (6) removing the formwork. Commercial concrete is directly input into the constructional column formwork through the root of the constructional column through a pump pipe by utilizing the conveying pressure of the concrete pump and is compactly packed. Atraditional constructional column concrete construction process is simplified, and the problems that constructional column concrete construction is not compact, vibration is difficult, concrete transportation is difficult, pouring at the joint of the top and the beam is not compact, and one-time construction cannot be achieved are solved.

Description

technical field [0001] The invention belongs to the technical field of building construction, and in particular relates to a self-compacting construction method for structural column concrete. Background technique [0002] Since the implementation of standards and norms related to structural columns, domestic research on structural columns has mostly focused on construction operation methods, mainly for quality problems such as grout running out, exposed tendons, pockmarked surfaces, broken roots and faults in the construction of structural columns. However, few people have been involved in the research on fundamentally changing the traditional practice of structural columns. In order to solve the construction difficulties and quality problems of traditional structural columns, and better adapt to the requirements of my country's new rural urbanization construction, the new technology of prefabricated structural columns has been developed. It mainly uses prefabricated blocks...

Problems solved by technology

[0003] Purpose of the invention: The purpose of the present invention is to address the deficiencies of the prior art and provide a self-compacting construction method for structural column concrete. The present invention uses the delivery pressure of the concrete pump to directly input the commercial concrete through the root of the structural column into the formwork of the structural column through the pump pipe. And fill it densely; the present invention simplifies the traditional structural column concrete construction technology, and solves the problems that the structural column concrete construction is not dense, difficult to vibrate, difficult to transport concrete, and the joint between the top and the beam is not densely poured and cannot be constructed at one time
