Prefabricated standard assembling piece and an assembly type reinforced concrete column using the same

Abstract

The invention belongs to the field of building structures, and particularly relates to a prefabricated standard assembling piece and an assembly type reinforced concrete column using the same. The assembling piece comprises a steel bar truss and a prefabricated concrete coating layer, wherein the steel bar truss comprises horizontal steel bars, longitudinal steel bars and web member steel bars; and the horizontal reinforcing steel bars extend out of one end of the prefabricated standard assembling piece to form a square hoop. The assembling piece has the advantages of being small in size, light in self weight and easy to transport. Meanwhile, the invention further provides an assembly type reinforced concrete column using the assembly piece, and the installation workload of the assembly type column can be reduced on the premise that the performance of the column is guaranteed. The concrete column comprises a prefabricated concrete outer layer and a cast-in-place concrete inner layer, the prefabricated concrete outer layer is formed by connecting prefabricated standard assembling pieces in the horizontal direction end to end. And the prefabricated concrete outer layer middle squarehoop and the longitudinal connecting steel bars in the prefabricated concrete outer-layer middle square hoop jointly form an embedded column framework.

Description

technical field [0001] The invention belongs to the field of building structures, and in particular relates to a prefabricated standard assembly piece and an assembled reinforced concrete column using the assembly piece. 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.

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
