Beam-wall mechanical connection sleeve reserved pre-embedded positioning device

The utility model discloses a beam-wall mechanical connecting sleeve reserved pre-embedded positioning device which comprises a U-shaped sliding guide rail fixed in a preset steel formwork, a fixed guide rail capable of sliding up and down is arranged in the U-shaped sliding guide rail, a connecting sleeve is placed in the U-shaped sliding guide rail, and the U-shaped sliding guide rail is provided with a fixed guide rail capable of sliding up and down. And the connecting sleeve is positioned by the fixed guide rail. The device is low in machining difficulty, can be machined according to the size of the cross section of a beam, the number of steel bars and the distance between the steel bars, and then is welded to the inner side of a creeping formwork in the construction process, deviation of the reserved pre-burying part in the pouring process is reduced, the reserved pre-burying positioning precision is improved, meanwhile, deviation of the sleeve can be avoided, and the construction efficiency is improved.
