Integrated beam-slab-column formwork structure system and construction method

Abstract

The invention relates to the technical field of construction engineering, in particular to an integrated beam-slab-column formwork structure system and a construction method. The structural system is a frame structure formwork system composed of unremovable column formwork, beam formwork, beam-column joint formwork and floor formwork; the column formwork, beam-column joint formwork, beam formwork and floor formwork are respectively spliced ​​by corresponding formwork units Composition; the demolition-free formwork unit is made of a thin-walled shell structure, used as a formwork when pouring concrete, and later used as a decoration material, one side is treated with a rough surface, and the other side is smooth; the joints of the formwork units are embedded with each other in the form of concave-convex grooves; The outer side of the demolition formwork is fastened with fastening hoops to resist the lateral pressure of cast-in-place concrete; the beam-column joint formwork makes the integrated beam-slab-column formwork structural system suitable for prefabricated structural components, and is also suitable for on-site cast-in-place; prefabricated components or cast-in-place concrete A building unit that forms a frame structure, and multiple building units form a multi-storey or high-rise frame structure.

Description

technical field [0001] The invention relates to the technical field of construction engineering, in particular to a frame beam-slab-column formwork structure system and a construction process that apply an industrialization model to the field of building structures. Background technique [0002] The traditional construction sequence of the frame structure is to tie the steel bars-support the formwork-pour the concrete-remove the formwork. This process is not only labor-intensive and material-intensive, but also the construction is relatively complicated. The quality of the components is greatly affected when the formwork is removed. For decoration, the bond between the plaster layer and the concrete surface is not strong, and hollow cracks are easy to occur, which takes a long time and costs a lot. For large-scale steel formwork pouring, large-scale hoisting equipment must be used for its installation and removal, and the safety risk factor is high. The emergence of prefabri...

[0002] The traditional construction sequence of the frame structure is to tie the steel bars-support the formwork-pour the concrete-remove the formwork. This process is not only labor-intensive and material-intensive, but also the construction is relatively complicated. The quality of the components is greatly affected when the formwork is removed. Decoration, the plaster layer and the concrete surface are not bonded firmly, and hollowing cracks are easy to occur, which takes a long time and costs a lot. For large-scale steel formwork pouring, large-scale hoisting equipment must be used for its installation and removal, and the safety risk factor is high. ;The emergence of prefabricated components has brought factoryization into the construction field, shortening the construction period, but the connection effect of beam-column joints is difficult to reach the level of cast-in-place, which affects the seismic performance of the entire structure
