Formwork supporting structure for reserved hole roof cover construction

Abstract

The invention discloses a formwork supporting structure for reserved hole roof cover construction. The structure comprises a plurality of layers of reserved holes. Fixed type steel beams are arranged at the two opposite side edges of an opening of the reserved hole in the top layer, a plurality of uniformly-distributed secondary beams are fixedly arranged between the two side steel beams, the two ends of the secondary beams are fixed to the two side steel beams, supporting scaffolds are erected on the two side steel beams, and bases of the supporting scaffolds are arranged on the two side steel beams respectively; two supporting beams below a board are arranged on the tops of the supporting scaffolds, the two supporting beams below the board are right opposite to the two steel beams, a plurality of uniformly-distributed secondary beams below the board are fixedly arranged between the two supporting beams below the board, and the two ends of the secondary beams below the board are arranged on the two supporting beams below the board respectively; a formwork is arranged above the supporting beams below the board and the secondary beams below the board. According to the formwork supporting structure, the problem that in the prior art, during reserved hole roof cover casting construction, potential safety hazards exist when a floor type formwork support is arranged is solved, and the purposes of lowering potential safety hazards while supporting is provided for reserved hole roof cover cast-in-place are achieved.

Description

Technical field [0001] The invention relates to the field of civil construction, in particular to a formwork support structure for reserved hole roof construction. Background technique [0002] In the civil construction of a large-scale complex project, the middle layer of the main structure will have several consecutive layers with large-area reserved holes, such as reserved holes for escalators, hollow-out reserved holes in the atrium, etc., which are reserved holes Usually the area is larger. In the prior art, when the concrete top cover at the top of the reserved hole is cast-in-place, the bottom formwork support frame can only adopt a floor-standing formwork support in a conventional way, usually a very high super-elevated structure. Complicated, time-consuming and labor-consuming, and at the same time, due to the high height, there are still greater safety risks. Summary of the invention [0003] The purpose of the present invention is to provide a formwork support structu...
