Embodiment 1

[0034] see Figure 1 to Figure 3 The present invention provides an on-site splicing structure of thin-coated steel concrete composite columns with better economic benefits and easier installation. The technical solution provides an assembled splicing node for composite columns; It is made by assembling or welding multiple sections of columns, and the technical concept of the prefabricated type is to leave the complex process in the factory for prefabrication and leave the simple process to the site, so it is possible to improve the efficiency of on-site construction, and the factory can be machined production, and it is more economical Energy saving. To this end, the splicing structure includes at least two H-shaped steels 1 , the sides of the H-shaped steels 1 are filled with thin clad concrete 11 , the rear end of the H-shaped steel 1 is provided with a first end plate 21 , and the head end is provided with a first end plate 21 . The second end plate 23, a rear cladding spa...

Embodiment 2

[0047] The present invention also provides a method for assembling the above-mentioned thin-coated steel concrete composite column on-site splicing structure, which includes two main steps, one is a prefabrication step in a factory, and the other is a construction step on the construction site. Here, the two steps of prefabrication and on-site installation only take the entire process of two H-beams 1 as detailed descriptions. As for how many H-beams 1 are required for on-site construction, it is only necessary to prefabricate the corresponding number of prefabricated columns according to S1, and then repeat S2 on-site installation. on-site installation steps. specific:

[0048] S1 Prefab:

[0049] A first end plate 21 and a second end plate 23 are welded to the tail end and the head end of the H-beam 1 respectively, and a first splicing hole 211 for splicing is opened in the first end plate 21, and the second end plate 23 A second splicing hole 231 for splicing is opened; a...

Abstract

The invention provides an on-site splicing structure and a splicing construction method.The splicing structure comprises at least two pieces of H-shaped steel 1, the side portions of the H-shaped steel 1 are filled with thin cladding concrete 11, the tail ends of the H-shaped steel 1 are provided with first end plates 21, and the head ends of the H-shaped steel 1 are provided with second end plates 23; a rear cladding space 13 used for splicing is reserved between the first end plate 21 and / or the second end plate 23 and the thin cladding concrete 11; a first splicing hole 211 is formed in the first end plate 21, a second splicing hole 231 is formed in the second end plate 23, the first splicing hole 211 and the second splicing hole 231 form a splicing joint in the rear wrapping space 13 through a splicing bolt 24, and the splicing joint and the rear wrapping space 13 are wrapped by rear wrapping concrete in a pouring mode.

Description

technical field [0001] The invention relates to the field of prefabricated building structures, in particular to an on-site splicing structure of thin-clad steel concrete composite columns and an assembling construction method thereof. Background technique [0002] There are many forms of prefabricated columns commonly used at present, but each has its own shortcomings, such as: [0003] Precast concrete column: heavy weight is difficult to hoist, and the connection node with the beam is generally cast-in-place wet connection; [0004] Steel column: need to do anti-corrosion paint, fire-proof coating, the economy is poor; [0005] Steel-reinforced concrete column: Due to the large thickness of concrete outside the steel frame and the large cross-sectional size (minimum side length 450mm), a large number of studs need to be welded on the steel frame, and the reinforcement configuration is complicated, which is inconvenient for prefabrication; [0006] CFST column: Although ...
