Embodiment 1

[0039] see figure 1 and figure 2 As shown, the lightweight concrete-filled steel tube composite column of the steel structure building consists of core steel pipe 1, concrete 2, lightweight thermal insulation mortar 3, lightweight thermal insulation block 4, masonry mortar 5, crack-resistant mortar 6, and glass fiber mesh cloth 7 components, wherein the lightweight thermal insulation mortar 3 uses polystyrene granular foam concrete slurry, and the lightweight thermal insulation block 4 uses polystyrene granular concrete blocks. The cross section of the steel pipe 1 is circular.

[0040] The construction method of this lightweight steel tube concrete composite column is as follows:

[0041] Step 1: Cutting the core steel pipe 1 in the steel tube concrete according to the design requirements, and pouring high-strength concrete that meets the standards or design requirements in the core steel tube 1 to form a steel tube concrete column;

[0042] Step 2. Weld and fix the steel...

Embodiment 2

[0048] See eg figure 1 , figure 2 As shown, the lightweight concrete-filled steel tube composite column of a steel structure building is composed of steel pipe 1, concrete 2, lightweight thermal insulation mortar 3, lightweight thermal insulation block 4, masonry mortar 5, crack-resistant mortar 6, and glass fiber mesh 7; The difference from Example 1 is that foamed cement paste is used for the lightweight thermal insulation mortar, and foamed concrete blocks are used for the lightweight thermal insulation blocks.

[0049] The construction method of this lightweight steel tube concrete composite column is as follows:

[0050] Step 1: Cutting the core steel pipe 1 in the steel tube concrete according to the design requirements, and pouring high-strength concrete that meets the standards or design requirements in the core steel tube 1 to form a steel tube concrete column;

[0051] Step 2. Fix the steel tube concrete column and other steel structural components in the building...

Abstract

The invention relates to a lightweight concrete-filled steel tube composite column for a steel structure building and a construction method. The lightweight concrete-filled steel tube composite column comprises an internal core steel tube, concrete in the core steel tube, lightweight thermal insulation mortar, lightweight thermal insulation building blocks and masonry mortar; the lightweight thermal insulation building blocks are vertically overlapped in layers in a staggered joint manner and transversely surround the outside of the core steel tube; a gap between every two adjacent lightweight thermal insulation building blocks is filled with the masonry mortar, so that the lightweight thermal insulation building blocks are adhered to form one whole body; the space between the lightweight thermal insulation building blocks and the core steel tube is filled with lightweight thermal insulation mortar by pouring; and the outer surfaces of the lightweight thermal insulation building blocks are coated with outer wall external thermal insulation defend tiers. According to the invention, the technical problems of heavy dead weight, poor anti-seismic property and high heat conductivity coefficient of outside concrete of a conventional concrete-filled steel tube composite column are solved, and the technical problem of consumption of materials and labor caused by damage to the outside concrete caused by welding when the composite column is installed is solved.

Description

technical field [0001] The invention relates to a novel concrete-filled steel tube composite column and its construction method, in particular to a concrete-filled steel tube composite column formed by pouring light-weight thermal insulation mortar into a mold and its construction method. Background technique [0002] With the improvement of people's living standards, there are more and more buildings with safer structures and higher comfort. Mid-rise and super high-rise buildings have also become one of the mainstreams of modern buildings. It not only improves the bearing capacity of the internal concrete, but also overcomes the shortcoming that the steel pipe structure is prone to local yielding. The effect of the combination of the two materials is far greater than the simple superposition of the two, giving full play to the advantages of concrete and steel pipes. [0003] As a superimposed construction of steel pipe concrete, the composite steel pipe concrete column can...
