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

Abstract

The invention relates to the technical field of constructional engineering, in particular to an integrated beam-slab-column formwork structural system and a construction method. The structural system is a frame structure formwork system composed of a non-dismantling column formwork, a beam formwork, a beam-column joint formwork and a slab formwork which are connected to each other; the column formwork, the beam-column joint formwork, the beam formwork and the slab formwork are respectively composed of corresponding formwork units by means of splicing; a non-dismantling formwork unit is made of a thin-wall shell structure and used as a formwork when pouring concrete, and also used as finishing material in the later stage, wherein one side of the non-dismantling formwork unit is processed into a rough surface and the other side is smooth; the splicing parts of the formwork units are built in by adopting a form of concave-convex groove and tongue; an outer side of the non-dismantling formwork is fastened by using a fastening hoop to resist the cast-in-situ concrete side pressure; the beam-column joint formwork makes the integrated beam-slab-column formwork structural system applicable to a preformed structural member, and also applicable to cast-in-situ; the preformed member is spliced or concrete is casted in situ to the preformed member to form one building unit of the frame structure, and a plurality of building units form a multilayer or a 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
