Composite fireproof anti-corrosion sound-insulation heat-preservation special-shaped steel pipe combination system and preparation method

Abstract

The invention relates to the technical field of steel pipe materials, and discloses a composite fireproof anti-corrosion sound-insulation heat-preservation special-shaped steel pipe combination system. The system comprises reinforcing ribs, steel pipes, web pipes, wing pipes, beams and columns, wherein connecting holes which are equally distributed are formed in the front faces of the web pipes, pouring auxiliary holes are formed in one faces of the web pipes, the left ends and the right ends of the web pipes and the wing pipes are fixedly connected with one sides of steel plates, and H-shapedsteel is formed between the reinforcing ribs and the steel pipes. According to the composite fireproof anti-corrosion sound-insulation heat-preservation special-shaped steel pipe combination system and a preparation method, the plasticity performance of a sectional material can be enhanced by arranging high-performance concrete of the steel pipes, brittle failure of the concrete in the pipes is prevented, the shock resistance is good, sound transmission generated by a steel structure can be effectively prevented by pouring the high-performance concrete into the steel pipes, a fireproof effectcan be achieved through a fireproof plate, and under the constraint of the steel pipes, the elasticity of the high-performance concrete is improved, and meanwhile the brittleness of the high-performance concrete is reduced.

Description

technical field [0001] The invention relates to the technical field of steel pipe materials, in particular to a combination system of composite fireproof, anticorrosion, sound insulation and heat preservation special-shaped steel pipes and a preparation method thereof. Background technique [0002] Steel structure housing is a project that my country will focus on promoting during the Tenth Five-Year Period. It has the characteristics of high strength, small structure size, light weight, fast construction speed, good seismic performance and high degree of industrialization. Housing industrialization is the only way for the development of my country's housing industry, because it will become a new growth point to promote my country's economic development. The steel structure residential system is easy to realize industrialized production and standardized production, and the matching wall materials can use new energy-saving and environmentally friendly materials. It is a green...

Problems solved by technology

[0004] The object of the present invention is to provide a combination system and preparation method of composite fireproof, anti-corrosion, sound-insulating and heat-insulating special-shaped steel pipes, which solves the problem that the existing steel is easy to rust, and protective measures should be taken, and the existing steel is heat-resistant but not high-temperature resistant. As the temperature rises, the strength decreases. When there is radiant heat around and the temperature is above 150 degrees, shielding measures should be taken. If a fire breaks out and the temperature of the structure reaches above 500 degrees, it may all collapse instantaneously. Secondly, The existing steel structure has high thermal conductivity, fast heat transfer and poor heat preservation performance, and the steel structure has fast sound transmission and poor sound insulation and vibration reduction effect
