Combined early-disassembly template device

Abstract

The invention discloses a combined early-disassembly template device, comprising an open-web steel frame plywood form block, a steel plate stamping beam, a horizontal steel pipe and a plate fastener frame, wherein the steel plate stamping beam and the horizontal steel pipe are respectively arranged at the upper part of the plate fastener frame, the open-web steel frame plywood form block is arranged on the horizontal steel pipe, the plate fastener frame comprises at least four plate fastener frame vertical column units, horizontal rods and inclined rods, and the four plate fastener frame vertical column units are connected through the horizontal rods and the inclined rods; each plate fastener frame vertical column unit comprises an inner inserting pipe, a main vertical rod sleeve, a base and an early-disassembly column head, the early-disassembly column head is connected with the upper part of the inner inserting pipe, and the base is fixedly connected with the bottom of the main vertical rod sleeve; and the horizontal steel pipe is arranged on the early-disassembly column head. The combined early-disassembly template device disclosed by the invention can be suitable for various change floor supporting moulds for construction of a beam plate and has the advantages of lighter self weight, larger rigidity, good economical duration performance and adjustable height.

Description

technical field [0001] The invention belongs to the field of formwork engineering for building engineering construction, and specifically relates to a combined early-demolition formwork device, which is suitable for manual assembly and disassembly of early-demolition formwork in the construction of cast-in-place concrete beam-slab structures in construction projects. Background technique [0002] The form work of cast-in-place concrete slab construction includes the formwork that contacts the concrete and shapes it and the support frame that supports the formwork. Reducing the configuration quantity of floor formwork and brackets and speeding up their turnover and use are the most concerned issues of the project department at present. At present, the construction of cast-in-place concrete slabs in construction projects mostly uses traditional wood plywood as the formwork panel, wooden squares or steel pipes with a diameter of 48mm as the panel back corrugation, and fastener-...

AI Technical Summary

Problems solved by technology

The top of the adjustable steel pillar is equipped with a lift-type early demolition column head. The top supporting plate of the column head is directly in contact with the concrete floor. The steel beam supporting the formwork can be placed on the casing that can be lifted and lowered by the column head. The span of the steel beam is less than 2m. Under the hammer and other tools, the clamping plate that prevents the sliding of the casing from sliding, the casing of the lifting column head, the steel beam and the formwork block are lowered by about 150mm, and the top supporting plate of the lifting column head is still supporting the floor. If it is less than 2m, the formwork blocks and supporting steel beams can be removed early; in this support system, the force-transmitting steel beams on which the formwork blocks are placed are fixed-length, and the versatility is poor; there are no formwork installation operators for independent adjustable steel pillars The standing horizontal bar does not match the habits of domestic workers

In addition, the formwork blocks in the known early-demolition formwork system are mainly steel frame plywood formwork blocks or aluminum alloy frame plywood formwork blocks with a solid web frame height of 75mm. Framed plywood formwork blocks are expensive and easy to be damaged

Due to the above-mentioned problems, the early demolition formwork matching the manual assembly and disassembly of formwork and the structural characteristics of Chinese concrete floors has not been well developed and applied. The promotion and application of technology has directly affected the realization of the goal of green construction led by the country
