Cast-in-place concrete plate fast-assembly and early-disassembly formwork system

Abstract

The invention belongs to the technical field of building formworks, and particularly relates to a cast-in-place concrete plate fast-assembly and early-disassembly formwork system which comprises a supporting column assembly, a frame beam and a face plate, the supporting column assembly comprises a steel pipe vertical rod and a screw rod, the screw rod is provided with two adjusting nuts, an early-disassembly support is arranged above the adjusting nut on the upper side, and a top support is fixed to the top of the screw rod. A transverse U-shaped support is arranged at the top of the early dismounting support, and limiting through holes are formed in the inner surfaces of the two ends, not provided with the limiting wing plates, of the horizontal plane of the transverse U-shaped support; the frame beam comprises a main beam and a small beam, and limiting rods matched with the limiting through holes are fixedly arranged at the positions, corresponding to the limiting through holes, of the bottom of the frame beam; the small beam is a combined type small beam, and a panel is erected above the top of the combined type small beam. Compared with the prior art, the formwork has the following advantages that all the components can be modularly produced in a factory and spliced on site, the geometric dimension of the formwork can be guaranteed, then the geometric dimension after concrete forming is guaranteed, the construction quality is guaranteed, the material turnover rate is increased, and the construction cost is reduced.

Description

technical field [0001] The invention belongs to the technical field of building formwork, in particular to a formwork system for quick assembly and early dismantling of cast-in-place concrete slabs. Background technique [0002] At present, the common construction industry formwork systems in the market include wood formwork, steel formwork, aluminum alloy formwork, and plastic formwork. Each system has its own advantages and is widely used in various construction projects. The existing formwork system has a complex structure. , There are many types. In order to shorten the construction period, the best solution is to design and produce formwork in advance, and on-site installation is the best solution. However, due to the different structures and construction conditions of different floors, the requirements for formwork systems are relatively high, and large quantities will appear during the design process.

[0002] At present, the common construction industry formwork systems in the market include wood formwork, steel formwork, aluminum alloy formwork, and plastic formwork. Each system has its own advantages and is widely used in various construction projects. The existing formwork system has a complex structure. , There are many types. In order to shorten the construction period, the best solution is to design and produce formwork in advance, and on-site installation is the best solution. However, due to the different structures and construction conditions of different floors, the requirements for formwork systems are relatively high, and large quantities will appear during the design process. The production of heterogeneous components leads to low turnover times, resulting in a great waste of resources and increasing construction costs

[0003] The existing concrete slab formwork construction scheme uses early dismantling lead screw U brackets locally, so that most of the formwork on the concrete slab surface can be dismantled in advance, but some components need to be further processed before installation to facilitate installation, and it is easy to appear during the dismantling process. Due to problems such as formwork falling, the geometric dimensions after formwork formation are limited by construction workers’ skills, sense of responsibility, material quality, temperature, humidity and many other factors, so the geometric dimensions of concrete formation cannot be guaranteed. Therefore, it is necessary to Involving a formwork construction system that is simple to use and easy to operate
