Problems solved by technology

[0004] The above-mentioned patent application has a complex structure with a large number of components, and the assembly is time-consuming and laborious; the structure is a pure steel structure. If you want to obtain a higher bearing capacity, the size of the column limbs is large, and there may be a phenomenon of "convex beams and columns"; there are a large number of On-site welding will easily lead to changes in the structure and performance of the welded joints of components, resulting in residual stress and deformation, affecting the quality of the structure, and reducing the bearing capacity; to ensure good welding quality, there are high requirements for the level of construction personnel; a large number of on-site welding and assembly lead to slow construction, which is not conducive to the requirements of the construction period

Embodiment 1

[0095] The present invention is a new type of steel-concrete combined special-shaped lattice column, which is composed of square steel pipe concrete column 1, channel steel 2, and strip 3, and adopts the form of type I "L" combined special-shaped lattice column. The sectional view is as attached figure 1 shown.

[0096] The square concrete-filled steel tube column 1 is a seamless square steel tube, and ordinary concrete C30 is poured inside, and it can also be any one of lightweight aggregate concrete or high-performance concrete, not limited to the above types.

[0097] There are four rows of first reserved holes along the length of the column on the square steel tube concrete column for the passage of bolts;

[0098] The channel steel 2 connected with the square steel tube concrete column 1 has high-strength bolt rods welded on its web plate, and four rows of high-strength bolt rods are arranged along the length direction of the channel steel. The reserved four rows of firs...

Embodiment 2

[0214] The difference from Example 1 is that Type I "T"-shaped composite special-shaped lattice column is adopted, and the cross-sectional view is shown in the attached figure 2 shown.

[0215] Lightweight aggregate concrete is poured inside the square steel tube concrete column 1 .

[0216] The steel of the combined special-shaped lattice column is selected from low-alloy high-strength structural steel Q390 grade.

[0217] All the other are identical with embodiment 1.

Embodiment 3

[0219] The difference from Example 1 is that the type I "ten"-shaped combined special-shaped lattice column is adopted, and the cross-sectional view is shown in the attached image 3 shown.

[0220] High-performance concrete is poured inside the square concrete-filled steel tube column 1 .

[0221] The steel of the combined special-shaped lattice column is selected from low-alloy high-strength structural steel Q420 grade.

[0222] All the other are identical with embodiment 1.

[0223] From the above structure, the present invention adopts square steel pipes, channel steels, and trim strips, and the above raw materials can be prefabricated in factories, which is fast in processing, convenient in construction, and improves the efficiency in specific construction, and because the present invention adopts the above-mentioned The structure can provide a variety of cross-sectional forms, which can effectively improve its bearing capacity and seismic performance while adapting to ...

Abstract

The invention relates to the technical field of steel structure houses and public buildings, in particular to a steel-concrete combined special-shaped lattice column. The combined special-shaped lattice column provided by the present invention is composed of square steel pipe concrete column, channel steel, and strips. There are two structural types, namely type I and type II, and each has three cross-sectional forms, which are "L" type , "T" and "Ten" shapes; Bolt-assembled K-shaped strips are used for connection. The present invention overcomes the problems of inflexible structural arrangement, difficulty in factory prefabrication of components and low degree of standardization of components in the prior art, and most of the components used can be prefabricated in the factory. Prefabricated autoclaved blocks form an "intelligent" combined special-shaped lattice column integrating structure, heat preservation and sound insulation.

Description

technical field [0001] The invention relates to the technical field of steel structure houses and public buildings, more specifically, it relates to a novel steel-concrete composite special-shaped lattice column. Background technique [0002] With the sustained and rapid economic growth and the continuous development of urbanization, the urban population has increased dramatically. In order to meet people's growing living and working needs, it has become an inevitable trend to build various economically applicable high-rise buildings in limited urban land resources. Although the steel pipe bundle composite structure system, multi-cavity steel pipe composite system, and fabricated steel beam column system studied at present have solved the problem of the upward development of steel structure houses, there are more or less convex beams and convex columns, inflexible structural layout, and structural components. Difficulties in factory prefabrication, a large number of wet ope...
