Rustproof construction process of steel structure building using structural steel beams coated with steel beam permanent formwork pouring concrete

Abstract

The invention discloses a rustproof construction process of a steel structure building using structural steel beams coated with steel beam permanent formwork pouring concrete. The rustproof construction process is characterized by comprising the following steps that (1) the structural steel beams are installed; (2) formwork steel angles are fixed; (3) steel beam permanent formworks are installed,specifically, the steel beam permanent formwork installation principle is that first outer beams are installed and then inner beams are installed and first main beams are installed and then secondarybeams are installed; (4) non-dismantling corrugated board bottom formworks are installed; (5) floor steel bars are bound; (6) mechanical pouring concrete is performed, specifically, floor debris is cleaned, then a mechanical pump sends goods concrete to pour the floor, and in principle, firstly concrete in the steel beam permanent formworks is packed and tamped and concrete is poured to the non-dismantling corrugated board bottom formworks; and (7) concrete watering curing is performed. The steel beam permanent formworks are filled with concrete and the concrete is poured to the non-dismantling corrugated board bottom formworks, the steel beams and all steam members are coated with concrete and not exposed, and the problem of structural steel beam long-term rust protection of the steel structure building is completely solved.

Description

technical field [0001] The invention relates to the steel structure construction industry, in particular to an antirust construction process for steel structure buildings using steel beams without form removal and pouring concrete to wrap structural steel beams. Background technique [0002] Prefabricated buildings have quickly been widely recognized and accepted by the society, and have been rapidly promoted and applied in the construction field. However, the structural frames of prefabricated buildings are still mainly reinforced concrete frames and steel structure frames, and their floors are generally cast-in-place. Concrete floors, although some reinforced concrete frame buildings have achieved a certain degree of prefabricated construction, it is still relatively difficult, and the construction process is complicated and difficult. [0003] Compared with the reinforced concrete frame building, the steel structure frame building has a much higher construction and assemb...

[0002] Prefabricated buildings have quickly been widely recognized and accepted by the society, and have been rapidly promoted and applied in the construction field. However, the structural frames of prefabricated buildings are still mainly reinforced concrete frames and steel structure frames, and their floors are generally cast-in-place. Concrete floors, although some reinforced concrete frame buildings have achieved a certain degree of prefabricated construction, it is still relatively difficult, and the process is complex and difficult to construct

[0003] Compared with the reinforced concrete frame building, the steel structure frame building has a much higher construction and assembly rate. In addition to the foundation, floor, and sloping roof panels, the cast-in-place concrete is used for on-site pouring, and its stressed beams, columns and other steel components and walls The body can be completely decorated and constructed, and its building assembly rate and construction efficiency have been substantially improved, but its fatal flaw is that the anti-rust treatment of exposed steel components is a difficult problem. The traditional method is to use paint for anti-rust treatment Compared with steel structures such as outdoors, bridges, and structures, it is relatively feasible regardless of the construction process or later anti-rust maintenance; but for the exposed steel components of civil buildings, paint coatings are used to prevent rust, the paint smell is harmful to people, and the later period Anti-rust maintenance by painting is quite difficult and not feasible, so it is of great practical significance to solve the long-term anti-rust problem of exposed components of steel structure frames in a scientific, simple and effective way
