Concrete sliding formwork construction method and device

Abstract

The invention discloses a concrete sliding formwork construction method and device. The concrete sliding formwork construction method comprises the following steps of pouring a beam slab bottom die, pre-burying steel bars as connecting bars, building a lifting frame buttress, binding the steel bars, installing a lifting frame, and installing a lifting device on the lifting frame. According to the concrete sliding formwork construction method, the lifting frame and the lifting device are arranged, a first oil cylinder and a second oil cylinder can be directly purchased on the market, the first oil cylinder and the second oil cylinder are rigidly connected with a first connecting base and a second connecting base correspondingly, the lifting of a sliding formwork is facilitated, the sliding formwork can be alternately lifted by the first oil cylinder and the second oil cylinder, original jacking is changed into lifting, the structure is simple, the occupied space is small, the construction efficiency can be improved, and the problems of complex structure and large occupied space of an existing jacking mode, incapability of normal jacking of a hydraulic machine in the stretching and retracting process, low construction efficiency, incapability of guiding of the sliding and lifting of the sliding formwork and easiness in certain deviation are solved.

Description

technical field [0001] The invention belongs to the technical field of sliding form, in particular to a concrete sliding form construction method and device. Background technique [0002] The sliding form includes not only ordinary or special tool formwork, but also comprehensive technologies such as power sliding equipment and supporting construction technology. The hydraulic jack is mainly used as the driving force for sliding, and under the synchronous action of groups of jacks, it drives The tool formwork or sliding frame slides along the newly formed concrete surface or the formwork surface, and the concrete is poured into the groove from the upper opening of the formwork in layers, and each layer is generally not more than 30cm thick. When the concrete in the lowermost layer of the formwork reaches a certain strength Finally, relying on the action of the lifting machine, the formwork groove slides along the poured concrete surface or the sliding frame slides along the ...

AI Technical Summary

Problems solved by technology

[0004] Aiming at the problems existing in the prior art, the present invention provides a concrete sliding form construction method and device, equipped with the first oil cylinder and the second oil cylinder, which can alternately lift the sliding form, changing the original jacking to lifting, the structure is simple, and the occupation The space is small and the advantage of improving construction efficiency solves the problem that the existing jacking method has a complex structure and takes up a lot of space. The hydraulic machine cannot be lifted normally during the expansion and contraction process, the construction efficiency is low, and the sliding form cannot be lifted. Guided, prone to certain deviations
