Fast lifting slip form

Abstract

The invention provides a fast lifting slip form, comprising a formwork, a formwork enclosure ring and a formwork gantry climbing mechanism, wherein the formwork comprises a molding enclosure plate and a toothed molding enclosure plate at the lower part of the molding enclosure plate; and the gantry vertical beam of the formwork gantry climbing mechanism is fixedly connected with the molding enclosure plate or the molding enclosure ring. In the technical scheme provided by the invention, the toothed molding enclosure plate is adopted at the lower part of the formwork, so that obvious deformation is not caused in the whole climbing distance bedding surface of a slip plate, the technical problem of large-area collapse is not easily caused, especially after the combination of the toothed molding enclosure plate structure with a steam curing structure, on the premise of ensuring construction quality, the construction progress is accelerated, therefore the building construction quality and progress problems are solved under low-temperature weather conditions.

Description

technical field [0001] The patent application of the present invention relates to a sliding form device for implementing concrete cast-in-place forming construction construction projects. Background technique [0002] Sliding form is a forming mold assembly mechanism used in cast-in-place concrete building construction. It mainly includes forming formwork, formwork enclosure, formwork door frame sliding mechanism, and the gap between two formworks, or between formwork and the foundation wall. Concrete is poured in layers from bottom to top in the sleeve groove. After the lower concrete in the sleeve groove reaches the condensation degree required by the technology, the whole set of sliding form slides up and moves up. Complete building molding construction. The templates in the existing sliding form are all rectangular slabs, and the technical requirement is that the template should be lifted when the lower poured concrete in the groove has not lost its plasticity, so as to...

AI Technical Summary

Problems solved by technology

[0003] At present, the main technical problem in slip form construction is how to accurately grasp the timing of formwork lifting, which is a key link that affects construction quality and construction progress

If the timing of the formwork sliding is early, the concrete layer just out of the formwork will have low plasticity loss, poor plasticity, easy deformation, or even collapse. If the timing of the formwork sliding is late, the concrete will be excessively solidified and stick to the formwork, resulting in the formwork being unable to slide up , or cause the upper layer to solidify and form cold seams, especially in low temperature climates, this technical problem is more prominent; another technical problem is that it takes a long time to wait for the forming of the sliding mold, the construction speed is slow, and the construction progress cannot be guaranteed

[0004] In addition, the technical understanding of using steam to speed up the curing and hardening of concrete is getting deeper and wider, and the application is becoming more and more extensive. However, most of the existing steam curing technologies are only for independent building components, and there is no steam curing combined with a sliding form mechanism. mechanism
