Embodiment 1

[0041] as attached Figure 1-5As shown, this embodiment provides a prefabricated composite wall based on steel pipes, including a prefabricated wall panel 1, a wall connector 2 and a foundation embedded part 3, the prefabricated wall panel 1 is arranged on the foundation beam 4; the prefabricated wall panel 1 Including steel pipe composite wall skeleton 11, blocks 12 and concrete outer cladding, the steel pipe composite wall skeleton 11 adopts a rib structure formed by assembling and welding multiple steel pipes, the rib lattice structure is filled with blocks 12, and the concrete outer cladding is wrapped in ribs On the outside of the lattice structure, the surroundings of the block 12 are bonded with the concrete outer cladding. Preferably, the blocks 12 are made of aerated concrete blocks, and the aerated concrete blocks are made of recycled aggregate concrete instead of traditional concrete materials, which can effectively alleviate the consumption of raw materials and the...

Embodiment 2

[0059] as attached Figure 1-4 , 6, the structural design principle and manufacturing process of embodiment 2 and embodiment 1 are basically the same, the difference is that the side rib column 111, the middle rib column 112, the upper rib beam 113, and the lower rib column in the steel pipe composite wall skeleton Both the rib beam 114 and the middle rib beam 115 are rectangular steel pipes.

[0060] In this embodiment 2, the frame of the steel pipe compound wall is welded by rectangular steel pipes in the factory. By setting rib column end plates at the ends of the rectangular steel pipes, the rectangular steel pipes in the steel pipe composite wall skeleton are all sealed structures. After the steel pipes are sealed, their The internal air cannot circulate, so the heat cannot be effectively transferred, which effectively improves the thermal insulation effect of the prefabricated composite wall; by sealing the ends of the rectangular steel pipes, it is ensured that there is...

Embodiment 3

[0063] as attached Figure 1-4 , 7, the structural design principle and manufacturing process of embodiment 3 and embodiment 2 are basically the same, the difference is that the side rib column 111, the middle rib column 112, the upper rib beam 113, the lower rib column in the steel pipe composite wall skeleton The rib beam 114 and the middle rib beam 115 are both made of rectangular steel pipes, the webs of which are parallel to the surface of the prefabricated wall panel 1, and the webs of the rectangular steel pipes are evenly provided with circular or elliptical through holes.

[0064] In this embodiment 3, circular or elliptical through holes should be opened according to the design requirements in the webs of rectangular steel pipe beams and rectangular steel pipe beam columns, so as to facilitate concrete pouring; both ensured the pouring quality of concrete when making wall panels, and To a certain extent, the bonding strength between steel and concrete is enhanced, an...

Abstract

The invention discloses a fabricated composite wall based on steel pipes and a construction method thereof. The fabricated composite wall comprises a prefabricated wallboard which is arranged on a foundation beam, the prefabricated wallboard comprises a steel pipe composite wall framework, building blocks and a concrete outer cladding layer, the steel pipe composite wall framework is of a rib lattice structure formed by splicing a plurality of steel pipes, and the rib lattice structure is filled with building blocks; wall connecting pieces are evenly arranged at the bottom end of the prefabricated wallboard and arranged at the joints of rib columns and rib beams of the prefabricated wallboard; and a foundation embedded part is embedded in the top end of the foundation beam, and the wall connecting part is connected with the foundation embedded part through a high-strength bolt. According to the fabricated composite wall, through the synergistic effect of the steel pipe composite wall framework and the concrete, the advantages of good tensile and compressive properties of the steel pipe and high compressive capacity of the concrete are fully utilized, and the bearing capacity and seismic performance of the fabricated composite wall are effectively improved; and the wall connecting pieces and the foundation embedded part are connected through high-strength bolts, dry connection of the foundation horizontal joint of the prefabricated wallboard is achieved, and stability is high.

Description

technical field [0001] The invention belongs to the technical field of civil engineering, in particular to an assembled composite wall based on steel pipes and a construction method thereof. Background technique [0002] The prefabricated building is a type of building that is produced in a factory and installed on a construction site. It has the advantages of fine quality components, large-scale production, high resource utilization, low environmental pollution, fast installation speed, low project cost and high project quality; The ribs of the traditional densely ribbed composite wall are made of reinforced concrete. Due to the small size of the reinforced concrete ribbed section and the small diameter of the steel bars, the vertical and horizontal bearing capacity of the traditional densely ribbed composite wall is low. Just can not be used in the middle of high-rise buildings, so far, the vast majority of traditional dense rib composite walls are only used in the middle ...
