Formwork support system and construction method of cast-in-place concrete beam-slab structure

Abstract

The invention provides a structure template supporting system for a cast-in-place concrete beam plate. The supporting system comprises a plurality of groups of supporting rod components, wherein each group of supporting rod components comprises a first supporting rod component and a second supporting rod component; each first supporting rod component comprises a telescopic supporting vertical rod, an adjustable top support, an adjustable base, a supporting beam and a joist; a plurality of trays are arranged on the telescopic supporting vertical rods in a sleeving mode; the adjustable top supports are arranged on the tops of the telescopic supporting vertical rods, and each second supporting rod component is formed in a manner that the beam support is additionally arranged on the telescopic supporting vertical rod of the first supporting rod component; the beam supports are arranged on the beam supports or the adjustable top supports, and the joists are arranged on the supporting beams; a horizontal rod is arranged on trays of the two adjacent telescopic supporting vertical rods, and the trays of all telescopic supporting vertical rods are connected to form the supporting system. The invention further provides a construction method for the structure template supporting system. The structure template supporting system is simple in structure and convenient to operate, so that the construction quality is improved.

Description

technical field [0001] The invention relates to the technical field of construction engineering, in particular to a formwork support system and construction method for cast-in-place concrete beam-slab structures. Background technique [0002] At present, in construction projects, for the formwork support system of cast-in-place concrete beam and slab structures, most of them use fastener-type steel pipe scaffolding or bowl-buckle-type steel pipe scaffolding, and the top of the fastener-type steel pipe scaffolding or bowl-buckle steel pipe scaffolding pole is adjustable. Jacking, then lay joists on the adjustable jacking, set joists on the joists, and then install beam slab formwork on the joists. This support system has the incompatibility between beam formwork support poles and floor formwork support poles. Common use leads to an increase in the amount of supporting poles, and it is difficult to erect the beam-slab formwork supporting poles, resulting in complex installatio...

[0002] At present, in construction projects, for the formwork support system of cast-in-place concrete beam and slab structures, most of them use fastener-type steel pipe scaffolding or bowl-buckle-type steel pipe scaffolding, and the top of the fastener-type steel pipe scaffolding or bowl-buckle steel pipe scaffolding pole is adjustable. Jacking, then lay joists on the adjustable jacking, set joists on the joists, and then install beam slab formwork on the joists. This support system has the incompatibility between beam formwork support poles and floor formwork support poles. Common use leads to an increase in the amount of support poles, and it is difficult to erect the support poles of the beam-slab formwork, resulting in complex installation processes and low installation efficiency

When the formwork support pole adopts the traditional adjustable steel pipe column, because the diameter of the inner casing and the outer casing of the column is different, which is inconsistent with the specification of the traditional horizontal rod, it is difficult to connect the vertical rod and the horizontal rod, and the quality is difficult to guarantee
