Wood formwork early-dismantling supporting device and construction application method

Abstract

The invention provides a wood formwork early-dismantling supporting device and construction application method. The wood formwork early-dismantling supporting device comprises a jacking part and an adjustable supporting plate part; the jacking part is composed of a steel top plate (1), a screw rod (2), an upper adjusting nut (3) and a lower adjusting nut (4), wherein the screw rod (2) is welded to the bottom of the steel top plate, and the upper adjusting nut (3) is installed on the screw rod in a sleeving mode; handles (8) are correspondingly welded to the two sides of the upper adjusting nut and the lower adjusting nut; the adjustable supporting plate part is composed of a tray (5) and a casing pipe (6) which penetrates through the center of the tray; the casing pipe is installed on the screw rod in a sleeving mode and is located between the upper adjusting nut and a top plate. According to the wood formwork early-dismantling supporting device, through finalized design, the structure is safe and reliable, installing and disassembling turnover is convenient, universality is high, formwork early dismantling can be implemented in formwork construction, and the problem that a formwork in the key position cannot be dismantled in advance during top plate formwork construction is solved.

Description

technical field [0001] The invention belongs to the technical field of building construction formwork supporting devices, and is used for supporting the roof formwork when the building construction engineering structures such as high-rise, super high-rise, multi-storey residential and public buildings (roof), frame structure beams, floor slabs, etc. are performing concrete pouring construction . Background technique [0002] For a long time, the support of building construction formwork has only been used with jacking and steel pipe scaffolding. In the traditional roof formwork support system, the removal time of the supporting steel pipe and roof formwork (wooden square and bamboo plywood) depends on the curing age of the concrete, that is, the component concrete. The strength and the span of beams and slabs are dismantled in accordance with the regulations, and cannot be dismantled in blocks, which takes up a lot of formwork and greatly limits the turnover rate of the form...

Problems solved by technology

[0002] For a long time, the support of building construction formwork has only been used with jacking and steel pipe scaffolding. In the traditional roof formwork support system, the removal time of the supporting steel pipe and roof formwork (wooden square and bamboo plywood) depends on the curing age of the concrete, that is, the component concrete. The strength and the span of beams and slabs shall be dismantled in accordance with the specifications, and cannot be dismantled in blocks, which occupies a large number of formwork and greatly limits the turnover rate of the formwork

In addition, buildings with various structures and different storey heights are constantly increasing, and the requirements for jacking versatility are constantly increasing, and existing technologies are difficult to meet these requirements
