Problems solved by technology

[0005] For this reason, the present invention provides a conveniently disassembled assembled fireproof steel structure to solve the problem of the existing fireproof steel structure, which does not have a corresponding fireproof filler inside and only sprays simple fireproof paint on its surface, which has poor fire resistance and The steel structures are mainly fixed by riveting or welding. The stability is poor, and the disassembly and assembly process is very time-consuming and laborious. It is impossible to flexibly adjust the height and support inclination of the steel structure according to the actual construction needs, and it is difficult to adapt to the current construction. demand problem

Abstract

The invention discloses an assembled fireproof steel structure convenient to disassemble, and particularly relates to the technical field of fireproof steel structures. According to the technical scheme, the assembled fireproof steel structure comprises a cylindrical outer pipe, a first round hole is formed in the cylindrical outer pipe and communicates with the outside, a first inner copper column is arranged in the first round hole, an outer thread is arranged on the outer wall of the first inner copper column, an inner thread is arranged on the inner wall of the first round hole, the first inner copper column is connected into the first round hole in a threaded mode, a material storage cavity is formed in the first inner copper column, a fireproof structure is arranged in the material storage cavity, and a sealing component is arranged at the top end of the material storage cavity. The fireproof steel structure has the beneficial effects that the height and the deflection angle can be flexibly adjusted, so that different construction requirements are met, the stability is better, the disassembly and assembly process is more convenient and rapid, no complex fixing structure exists, the whole fireproof steel structure is more scientific and reasonable in design, the manufacturing cost is lower, the application range is wider, and the fireproof steel structure is worthy of being popularized and used in the later period.

Description

technical field [0001] The invention relates to the technical field of fireproof steel structures, in particular to an assembled fireproof steel structure which is easy to disassemble. Background technique [0002] Steel is characterized by high strength, light weight, good overall rigidity, and strong resistance to deformation, so it is especially suitable for building large-span, ultra-high, and ultra-heavy buildings; the material has good homogeneity and isotropy, and is ideal elasticity body, which is most in line with the basic assumptions of general engineering mechanics; the material has good plasticity and toughness, can have large deformation, and can withstand dynamic loads well; the construction period is short; its high degree of industrialization can carry out specialized production with a high degree of mechanization, In modern buildings, in order to further improve the stability and fire resistance of the building, fire-resistant steel structure materials are ...
