Embodiment Construction

[0041] Below in conjunction with accompanying drawing, the present invention is described in further detail:

[0042] like figure 1 As shown, it is the self-supporting node connection structure of concrete prefabricated components according to the present invention, including hollow column 1 , beam 2 and I-shaped self-supporting structure 3 .

[0043] like figure 2 and image 3 As shown, the hollow column 1 can be a cylinder or a square column. In this embodiment, a square column is used. The wall thickness of the hollow column is 20-30 mm. Fixed on the inner wall, 1 / 2 of the cross section of the column continuous stirrup 5 is embedded in the inner wall, and 1 / 2 protrudes from its inner surface.

[0044] The hollow column 1 is provided with a first reinforcing bar 6, and the first reinforcing bar 6 is arranged along the length direction of the hollow column 1. In this embodiment, the number of the first reinforcing bar 6 is eight, which are respectively located in the cent...

Abstract

The invention discloses a self-supporting node connection structure of concrete prefabricated components and an installation method thereof, comprising a hollow column, a beam and an I-shaped self-supporting structure; the hollow column is filled with concrete, and a through hole is arranged at the center of the concrete. The axial direction of the through hole is consistent with the length direction of the hollow column; the interior of the beam is provided with right-angle partitions at the end positions, which isolates the hollow area below the end of the beam, the end of the beam is provided with a gap in the hollow area, and the beam is in the hollow area. The interior is filled with concrete; I-type self-supporting structure includes T-shaped support and butterfly support; T-shaped support includes base plate and support column, and the support column is vertically arranged on the base plate; butterfly support includes sleeve, vertical plate and The horizontal plate, the sleeve is nested and fixed on the support column, one end of the vertical plate is connected with the sleeve, and the horizontal plate is arranged on the other end of the vertical plate; the height of the hollow area at the end of the beam is equal to the distance from the bottom of the bottom plate to the top of the horizontal plate. Reduce bolts and other connecting parts, the installation method is convenient, and the installation efficiency is improved.

Description

technical field [0001] The invention belongs to the field of prefabricated concrete structures, and relates to a self-supporting node connection structure of concrete prefabricated components and an installation method thereof. Background technique [0002] At present, most of the buildings in our country are constructed with cast-in-place reinforced concrete technology. With the popularization and application of prefabricated concrete technology, in order to ensure that the structural performance of prefabricated concrete structures is not lower than that of cast-in-place concrete structures, my country has also formulated corresponding technical specifications for concrete structures, including structural design, component prefabrication, and on-site construction. The basic idea is to pass the cast-in-place concrete structure through reasonable disassembly, factory prefabricated components, and on-site assembly. The disassembly is conducive to factory prefabrication and on-...
