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 column...

Embodiment 1

[0048] In the first embodiment, the prefabricated reinforced concrete column is a solid rectangular prefabricated reinforced concrete column.

[0049] Such as Figure 1-2 As shown, a prefabricated reinforced concrete column is composed of a prefabricated concrete outer layer 10 and an in-situ concrete inner layer 20 enclosed by prefabricated standard assembled pieces, wherein the outer layer prefabricated standard assembled pieces contain steel bar trusses, and Such as Figure 2-3 Shown, steel bar truss is made up of horizontal steel bar 12, longitudinal steel bar 13 and web bar steel bar 14. The horizontal steel bar 12 is connected with the longitudinal steel bar 13 by binding, and extends out of one end of the prefabricated standard assembly piece to form a zigzag closed hoop 12a. The shape of the web steel bar 14 is as follows Figure 2-4 The shown wave shape, and the top of the crest and the longitudinal reinforcement 13 are connected by binding or welding, while the to...

Embodiment 2

[0059] In the second embodiment, the prefabricated reinforced concrete column is a hollow or solid rectangular prefabricated reinforced concrete column.

[0060] Such as Figure 5-6 As shown, the prefabricated reinforced concrete column is also composed of a prefabricated concrete outer layer 10 and a cast-in-place concrete inner layer 20 formed by enclosing the end to end of the prefabricated standard assembly pieces. The cast-in-place concrete inner layer 20 is a hollow or solid section, and the inside is equipped with vertical reinforcement 21, stirrup 22, longitudinal connection reinforcement 15, steel pipe 24 or section steel 23. in the vertical direction as Figure 7 As shown, the prefabricated reinforced concrete column is formed by assembling the prefabricated standard assembly pieces in sections and pouring the cast-in-place concrete inner layer 20 in sections. Complete the connection.

[0061] In the specific implementation process, the steel pipe 24 or section st...

Embodiment 3

[0064] In the third embodiment, the prefabricated reinforced concrete column is a circular prefabricated reinforced concrete column.

[0065] Such as Figure 9 As shown, in the horizontal direction, the prefabricated reinforced concrete column is composed of such as Figure 8 The prefabricated concrete outer layer 10 and the cast-in-place concrete inner layer 20 formed by the fan ring-shaped prefabricated standard assembly pieces enclosed end to end are formed. Wherein, the outer prefabricated standard assembly piece contains steel bar trusses, while the cast-in-place concrete inner layer 20 is a solid section, and is provided with a three-dimensional grid skeleton composed of vertical steel bars 21, stirrup bars 22 and longitudinal connecting steel bars 15. In the vertical direction, the prefabricated reinforced concrete column is formed by assembling the prefabricated standard assembly pieces in sections and pouring the cast-in-place concrete inner layer 20 in sections. Gr...

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,...
