Floor down-turning thin-walled concrete integral fabricated steel formwork structure operating on same floor

Abstract

The invention discloses a floor down-turning thin-walled concrete integral fabricated steel formwork structure operating on the same floor. The floor down-turning thin-walled concrete integral fabricated steel formwork structure comprises a steel formwork groove, an opening of the steel formwork groove is formed upwards, the steel formwork groove is filled with reinforced concrete, the upper portion of the outer wall of one side of the steel formwork groove is attached to the outer end face of the floor, and the upper edges of the side walls of the two sides of the steel formwork groove are fixedly connected with the outer edge of the floor. According to the fabricated steel structure building, reinforced concrete plates are turned downwards around the floor, the steel formwork groove is adopted as a formwork so that the reinforced concrete plate can be prefabricated, the steel formwork groove does not need to be disassembled, construction is convenient, the structural strength is high, and the effect of fireproof separation is achieved; ground construction operation is carried out on the same floor, and high-altitude edge operation protection cost and safety risks are reduced; andthe comprehensive economic value of the overall construction cost is high, and the floor down-turning thin-walled concrete integral fabricated steel formwork structure is suitable for application andpopularization of fabricated steel structure similar projects.

Description

technical field [0001] The invention relates to the technical field of steel structure and concrete mixed buildings, in particular to an integrally assembled steel formwork structure for turning down thin-walled concrete on the same floor. Background technique [0002] In the super-high concrete building structure, the floors without walls must be fixed on the outside of the floor with the turned-down edge board. The traditional concrete structure uses the formwork to inject the reinforced concrete structure on the outside of the floor to form the edge The edge board plays the role of fire separation. Among them, when setting the formwork and the injection-molded reinforced concrete structure, it is necessary to erect scaffolding and support frames on the lower floor, which are used for the construction of personnel and the support of the formwork respectively. However, scaffolding is erected around super high buildings Very dangerous and time consuming. [0003] At present...

Problems solved by technology

[0002] In the super-high concrete building structure, the floors without walls must be fixed on the outside of the floor with the turned-down edge board. The traditional concrete structure uses the formwork to inject the reinforced concrete structure on the outside of the floor to form the edge The edge board plays the role of fire separation. Among them, when setting the formwork and the injection-molded reinforced concrete structure, it is necessary to erect scaffolding and support frames on the lower floor, which are used for the construction of personnel and the support of the formwork respectively. However, scaffolding is erected around super high buildings Very dangerous and time consuming

[0003] At present, due to the development of prefabricated steel building structures, super high buildings can also be prefabricated steel building structures, or mixed buildings of steel building structures and reinforced concrete, combined with the advantages of rapid construction and structural strength of steel structures, super high buildings The floor of the building is formed by steel structure assembly, but the super high building still needs to set up the reinforced concrete edge board on the outside of the floor. The construction needs to be carried out on the adjacent next floor facing the previous floor. There are problems such as difficult connection, difficult construction and high cost, and there is no similar plan to learn from.
