Description

Technical Field

[0001] The invention belongs to the technical field of building construction, and in particular relates to a rapid reinforcement device and a reinforcement method for a floor conveying pump pipe. Background Art

[0002] At present, in high-rise building concrete construction projects, the traditional reinforcement method for conveying pump pipes passing through reserved holes in floor slabs is usually to insert wooden wedges between the conveying pump pipe and the reserved hole after the vertical conveying pump pipe passes through the hole, so as to block the gap between the pump pipe and the reserved hole in the floor slab. However, this method is not strong enough for reinforcement. During the concrete pouring process, the fixed wooden wedges are easy to fall off due to the up and down floating of the pump pipe during the plastering process, resulting in the lack of reinforcement of the pump pipe. At the same time, the up and down floating and left and right swinging of the pump pipe will also cause a certain probability of damage to the pump pipe, resulting in the increase of manpower to replace the pump pipe in the later stage. If the replacement time is too long, it will directly lead to the blockage of the pump pipe. In severe cases, it will cause the friction between the template and the pump pipe at the reserved hole of the working layer, causing the formwork system to become unstable and collapse. The existing technology also uses reinforcement devices such as fixed frames, but most of them have complex structures, cumbersome installation, and low work efficiency. Therefore, it is necessary to develop a new type of rapid reinforcement device. Summary of the invention
