Embodiment 1

[0034] Such as figure 1 As shown, the assembled circular steel pipe casing fiber concrete column connection node of the present invention includes an outer high-strength circular steel pipe 1, an inner high-strength circular steel pipe 2 and a circular casing conversion partition plate 4, and an inner high-strength circular steel pipe The steel pipe is located in the outsourced high-strength circular steel pipe and is concentric with the outsourced high-strength circular steel pipe. The upper and lower steel pipe casing fiber concrete columns are connected by a circular sleeve conversion partition plate, and the outside of the outsourced high-strength circular steel pipe is welded with an outer reinforcement ring. 10. The outer reinforcing ring is connected to the steel beam 11 by means of welding or bolting.

[0035] Such as figure 2 Both ends of the outer high-strength circular steel pipe and the inner high-strength circular steel pipe are provided with wedge-shaped connec...

Embodiment 2

[0048] The difference between this embodiment and Embodiment 1 is that there are two groups of wedge-shaped connecting teeth on the side wall of each steel pipe, the central angle of each group of wedge-shaped connecting teeth is 90 degrees, and the interval angle between each group of wedge-shaped connecting teeth is 90 degrees. Such as Figure 7 shown. All the other are identical with embodiment 1.

Abstract

The invention relates to the technical field of structural engineering, and discloses a connection joint of a fabricated circular steel tube casing fiber concrete column. The connection joint of the fabricated circular steel tube casing fiber concrete column comprises an outer-wrapped high-strength circular steel pipe, an inner sleeve high-strength round steel pipe and a circular casing conversion splitter plate, wherein wedge-shaped connecting teeth are arranged at the two ends of the outer-wrapped high-strength round steel pipe and the inner sleeve high-strength round steel pipe, the wedge-shaped connecting teeth are uncontinuously and evenly distributed along the circumference. The circular casing conversion splitter plate comprises a circular plate. A center through-hole is formed in the central position of the circular plate, the upper and lower faces of the circular plate are provided with vertical partition boards, each vertical partition board is provided with wedge-shaped chutes matched with the wedge-shaped connecting teeth, and the steel pipe and the circular casing conversion splitter plate are fixedly connected by the coordination between the wedge-shaped connecting teeth and the wedge-shaped chutes. According the connection joint and installation method of fabricated circular steel tube casing fiber concrete column, field welding between high-strength circular steel pipes is avoided, the reliability of the joint is improved, the steel part of the whole joint is produced by a factory and is assembled on the site, the concrete is poured on the site, and the influence of the construction on the quality is furthest minimized.

Description

technical field [0001] The invention relates to the technical field of structural engineering, in particular to an assembled circular steel pipe casing fiber concrete column connection node and an installation method. Background technique [0002] Due to the excess steel production in my country, the country strongly supports fabricated steel structure buildings. High-strength steel has been widely used in building structures. It is conducive to the development of my country's building industrialization, improving production efficiency and saving energy, developing green and environmentally friendly buildings, and improving and guarantee the quality of construction projects. Prefabricated steel structure buildings are conducive to green construction, because prefabricated construction can better meet the requirements of green construction such as land saving, energy saving, material saving, water saving and environmental protection, reduce the negative impact on the environme...
