Description

Technical Field

[0001] The utility model belongs to the technical field of building construction, in particular to a fixing device for a rotatable floor sleeve. Background Art

[0002] In the construction of modern high-rise buildings, most of the pipelines passing through the floor slabs are required to be worn in casings. At the same time, due to problems with the conventional casing fixing method, many casings are found to be not in a vertical direction during the later stage of pipe insertion. At this time, chiseling out and pre-embedding the casing will increase the cost. In order to reduce the cost, a post-cast slab is generally set here, and a hole is reserved during the structural construction. The casing is buried and the post-cast slab concrete is poured after the line is laid from top to bottom. Although this method can ensure the positioning of the casing, the cost of the secondary pouring is relatively high. For this reason, a casing fixing device is needed to reduce the cost.
