Assembly type reinforced concrete column construction process based on prefabricated standard assembling pieces

Abstract

The invention belongs to the field of building structures, and particularly relates to an assembly type reinforced concrete column construction process based on prefabricated standard assembling pieces. The assembly type reinforced concrete column construction process comprises the following steps of (1) building a three-dimensional grid framework; 2) assembling the prefabricated standard assembling pieces; 3) forming a prefabricated concrete outer layer; and 4) forming the cast-in-place concrete inner layer. On one hand, a series of construction quality problems such as the honeycomb pitted surface of the outer surface of the column in cast-in-place construction are avoided; on the other hand, compared with a traditional assembly type column, is adopted; the single assembling component has the advantages of being small in size, light in self weight, easy to transport, free of large construction machinery and the like, the assembly type column installation workload can be reduced on the premise that the column performance is guaranteed, construction is convenient, the construction efficiency is improved, the application range of the fabricated structure is further expanded, and themarket prospect is wide.

Description

technical field [0001] The invention belongs to the field of building structures, and in particular relates to a construction process for assembled reinforced concrete columns based on prefabricated standard assembled pieces. Background technique [0002] Construction industrialization is the mainstream development trend of the construction industry after the social and economic development enters the middle and high income level. For more than half a century, construction industrialization has been widely used at home and abroad. Compared with foreign countries, since my country has always been dominated by cast-in-place construction, the technical foundation and condition reserves of industrialized buildings are relatively weak. In recent years, with the rapid development of my country's economy, in order to meet the needs of the development of my country's construction industrialization, government departments have carried out corresponding policy support. On February 6,...

Problems solved by technology

[0003] When the cast-in-place concrete column is constructed on site, it needs to complete a series of processes from steel bar binding, formwork support to concrete pouring and maintenance. The construction volume is large and the construction period is long. In addition, a large amount of formwork materials are consumed in the process of formwork support and formwork removal, resulting in waste.

However, the existing prefabricated concrete columns often adopt the form of single-layer segmented columns; although the prefabricated assembled columns of this structure have the advantages of shortening the on-site construction period and saving energy compared with cast-in-place concrete columns, but due to It manufactures and constructs structural columns in units of layers. For structural columns with large cross-sections in large and medium-sized buildings or bridge structures, it is easy to cause a single prefabricated column to have a large weight and volume, resulting in cumbersome transportation and installation work and poor safety. , which brings many problems to the actual construction
