Template overhanging construction method for floor system with composite structure by utilizing profiled steel beams

Abstract

The invention discloses a template overhanging construction method for a floor system with a composite structure by utilizing profiled steel beams. In the construction method, the profiled steel beams are utilized for overhanging templates to establish a supporting system; H-shaped steel joists are used as mail joists; the main joists are connected with the profiled steel beams through overhanging rings; a template system is suspended on the profiled steel beams, and the excellent mechanical properties of the H-shaped steel joists are sufficiently utilized to effectively transmit loads of the upper template to the profiled steel beams, so that the defects of the lower full hall scaffold supporting system of templates are overcome, the method is safe and reliable, the construction progress is greatly enhanced, and the labor intensity of workers is reduced; besides, the template system can be recycled, so that the use rate of materials is increased, and the construction cost is reduced; besides, the templates and sub-joists are made of macromolecular plastics, so that the loads of the template system are greatly reduced, and the whole stability of the supporting system is largely improved; materials are not easy to damage, so that the material turnover rate is greatly increased; the method is specially suitable for the construction of steel structural concrete floor and frame-structure concrete floor plates of high-rise buildings.

Description

technical field [0001] The invention relates to a formwork-hanging construction method, in particular to a formwork-hanging construction method for a composite structure floor utilizing shaped steel beams, and belongs to the technical field of formwork support systems. Background technique [0002] At present, in my country's high-rise and super-high-rise structures, two construction methods are widely used for the support system of the steel structure outer frame floor: one is the traditional steel pipe full frame + wooden square + formwork as the support system, this method is safe and reliable, but The construction progress is slow, the labor intensity of the operator is high, and the cost is high; the other is the floor deck system of profiled steel plate or steel truss that is convenient for construction and stable in quality, but this method is relatively expensive, and the profiled steel plate is One-way bearing plates cannot meet the conditions of use in some construct...

[0002] At present, in my country's high-rise and super-high-rise structures, two construction methods are widely used for the support system of the steel structure outer frame floor: one is the traditional steel pipe full frame + wooden square + formwork as the support system, this method is safe and reliable, but The construction progress is slow, the labor intensity of the operator is high, and the cost is high; the other is the floor deck system of profiled steel plate or steel truss that is convenient for construction and stable in quality, but this method is relatively expensive, and the profiled steel plate is One-way bearing plate cannot meet the conditions of use in some construction situations

[0003] In addition, the support systems used in the construction of the above two steel structure outer frame slabs still have low formwork reuse rate and excessive material waste, which greatly increases the construction cost, and the formwork system itself has a heavy load, which leads to the overall failure of the support system. Reduced stability
