Description

Technical Field

[0001] The utility model relates to the technical field of auxiliary devices for reserved holes, in particular to a combined reserved hole alignment device. Background Art

[0002] Reserved holes refer to the holes reserved for the burial of water supply, heating and other equipment pipes in the main body of the building during construction. Especially for high-rise buildings, the water supply and heating equipment pipes in the high-rise buildings need to pass through the floor slabs. Reserved holes are required for almost every floor slab. If these reserved holes can be aligned up and down, the corresponding pipeline layout will be relatively simple; if these reserved holes are horizontally misaligned, the difficulty of corresponding pipeline layout will increase; if the horizontal misalignment is serious, the pipeline equipment cannot be installed normally. The reserved holes are formed by supporting the formwork when the floor slab is poured; when the floor slab is poured, the formwork is supported in the correct position, and the size of the formwork corresponds to the reserved hole, so that the reserved hole can be aligned up and down; the existing construction method is based on the designated load-bearing column that runs through the building, and the reserved hole formwork is performed at the same position when each floor slab is poured.
