Description

Technical Field

[0001] This application relates to the technical field of shaft construction, and particularly to a shaft formwork reinforcement and demolition device and a shaft formwork system. Background Art

[0002] At the present stage, the industrialization development speed in our country is getting faster and faster, and the requirements for the one-time forming quality of building structures are getting higher and higher during the construction process. In the traditional building construction process, most of the caissons, elevator shafts, energy dissipation shafts, etc. adopt reinforced concrete structures. During the construction process, it is necessary to install formwork support structures in the shaft to support the wall formwork. In the related technologies, it is rather troublesome for workers to carry and reinforce the formwork support materials. Especially when operating in a relatively small space of the shaft, it is even more inconvenient to operate, and the installation efficiency is low. If the formwork is not firmly reinforced, it is easy to cause problems such as formwork bulging in the shaft, insufficient thickness of the steel bar protection layer, and large structural deformation. In severe cases, structural distortion may occur, affecting the normal function. After the construction is completed, it is also necessary to remove the formwork support structures one by one, which is time-consuming and labor-intensive. Utility Model Content
