Problems solved by technology

Compared with the cast-in-place reinforced concrete column, the concrete column of this structure can shorten the construction period, but because the concrete is prefabricated in the single-layer segmented column, the weight and volume are large, and the transportation and installation workload is relatively large. less secure installation
[0006] Like the prefabricated reinforced concrete columns, the connection nodes of the current steel pipe concrete columns and steel concrete columns are also prefabricated on site, and the structural columns of this structure use a lot of steel and are expensive

Embodiment 1

[0072] Figure 1 to Figure 12 The standard assembly section in the shown embodiment one is a square column.

[0073] figure 1 It is a structural schematic diagram of the composite column of Embodiment 1 of the present invention, such as figure 1 As shown, the composite column of this embodiment is formed by splicing and fixing the upper and lower parts of the standard assembly section 1 assembled from prefabricated components and pouring in-situ concrete. The ends of two adjacent standard assembled sections 1 are welded and fixed, and are connected by several structural bars 2 anchored in the concrete, and the two ends of the structural bars 2 respectively extend into the single-layer section frame 11 ( mentioned below), such as figure 2 As shown, the length extending into the single-layer segmented frame 11 is at least LaE, and LaE is the seismic anchorage length, and the specific value of LaE can be obtained by looking up the table according to requirements.

Embodiment 2

[0112] The standard assembly section in the second embodiment is a circular column.

[0113] Such as Figure 13 As shown, the single-layer segmented frame in Embodiment 2 is the same as Embodiment 1, and is also composed of a main steel frame 111, a finished plate 113 surrounding the main steel frame, and a reinforcement cage 112 welded in the main steel frame 111. . The column longitudinal bars 112a in the reinforcement cage 112 are arranged circumferentially along the inner wall of the main steel frame 111 to form a cylindrical shape corresponding to the inner profile of the main steel frame 111 .

[0114] In this embodiment, the main steel frame 111 includes steel hoops 111b, and four vertically arranged and cylindrical support plates 111c. The steel hoops 111b are connected to adjacent support plates 111c for shaping to form a steel frame. The support plate 111c is an arc-shaped plate, and the four support plates 111c are evenly distributed on the circumference of the cy...

Embodiment 3

[0121] The standard assembly section in the third embodiment is a special-shaped column.

[0122] Such as Figure 17 As shown, the single-layer segmented frame in the third embodiment is the same as the first embodiment, and is also composed of the main steel frame 111, the finished plate 113 surrounding the main steel frame, and the reinforcement cage 112 welded in the main steel frame 111. . The column longitudinal bars 112a in the reinforcement cage 112 are arranged circumferentially along the inner wall of the main steel frame 111 to form a columnar structure with a trapezoidal cross-section whose shape corresponds to the inner shape of the main steel frame 111 .

[0123] In this embodiment, the main body steel frame 111 includes a support plate 111c and a corner member 111a. Both the support plate 111c and the corner member 111a are arranged vertically. Between the two corner members 111a on the long side, a trapezoidal column structure is formed. The main steel frame 1...

Abstract

The invention discloses a standard assembly section of an assembly-type concrete composite column and the composite column formed through the assemble section. The standard assembly section comprises a single-layer section frame in a single-layer section column and steel joints, the single-layer section frame comprises a main steel frame and a steel reinforcement cage arranged in the main steel frame, the steel joints serving as prefabricated parts are fixed at the top and / or bottom of the single-layer section frame to form a columnar steel frame with the single-layer section frame, the interior of the steel frame is provided with one concrete pouring channel which is through up and down, and the concrete pouring channel is used for splicing and fixing a plurality of assembly sections end to end prior to concrete pouring in site construction so as to construct the assembly-type concrete composite column. The standard assembly section is light and easy to transport, transportation cost is greatly reduced, safety in transportation and construction is improved, installation load in assembly of the assembly-type concrete composite column can be greatly reduced on the premise that performance of the composite column can be guaranteed, and construction efficiency in prefabricating the assembly column is improved.

Description

technical field [0001] The invention relates to a building structural member in the technical field of construction engineering, in particular to a standard assembly joint for constructing an assembled concrete composite column, and also to an assembled composite column composed of the standard assembly joint. Background technique [0002] The General Office of the State Council promulgated "Several Opinions on Promoting Housing Industrialization and Improving Housing Quality" in 1999. On January 1, 2013, in the form of 2013 No. 1 document, the National Development and Reform Commission and the Ministry of Housing and Urban-Rural Development "Green Building Action Plan" (State Council Attachment 1 of Banfa [2013] No. 1), the document focuses on fully understanding the implementation of green building actions, and lists "promoting the industrialization of construction" as one of the ten important tasks. [0003] At present, the structural columns used in buildings in various ...
