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

Embodiment 1

[0041] In the first embodiment, the prefabricated reinforced concrete column is a solid rectangular prefabricated reinforced concrete column.

[0042] 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 one end of the prefabricated standard assembly piece is extended to form a square hoop 12a. The shape of the web steel bar 14 is as follows Figure 2-4 Shown is wavy, and its crest top and longitudinal steel bar 13 are connected by binding or welding, while the top of its trough protrudes from ...

Embodiment 2

[0052] In the second embodiment, the prefabricated reinforced concrete column is a hollow or solid rectangular prefabricated reinforced concrete column.

[0053] 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.

[0054] In the specific implementation process, the steel pipe 24 or section st...

Embodiment 3

[0057] In the third embodiment, the prefabricated reinforced concrete column is a circular prefabricated reinforced concrete column.

[0058] 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 segmental assembly of prefabricated standard assembly pieces, and then the cast-in-place concrete inner layer 20 is poured in sections. ...

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. On February 6, 2016...
