Building top plate vertical drilling device used for building construction

Abstract

The invention discloses a vertical drilling device for building roofs for building construction, comprising a base plate, a plurality of casters are installed on the lower edge side of the base plate, and a plurality of threaded holes are opened on the base plate, threaded columns are screwed into the threaded holes, threaded The bottom end of the column is fixedly connected in the installation hole of the rotating shaft sleeve; the bottom plate is positioned horizontally by adjusting the rotating handle, which can ensure the verticality of the drilling hole, and the lifting column is moved upward by toggling the toggle block, which is easy to operate , Fast, easy to quickly adjust the height of the drill bit, press the two limit positions inward with your hand at the same time, so that the movable column moves to a certain place, so it is convenient to adjust the depth of the drill bit, the dust from the drill hole falls into the ring sleeve and It is discharged through the discharge pipe. Since the annular plate can shrink into the annular sleeve, the upper part of the annular plate is in contact with the roof of the building during the drilling process, so that the dust will not fall to the outside of the annular plate and improve the construction environment.

Description

technical field [0001] The invention relates to the technical field of building construction, in particular to a vertical drilling device for building roofs used in building construction. Background technique [0002] Building structural engineering masonry structural column chemical reinforcement drilling, decoration engineering ceiling suspender drilling, installation engineering pipeline suspender drilling, etc., often need to drill a large number of holes on the concrete roof during construction. At present, the traditional construction technology is manually operated by people climbing on the ladder, and the arms are forced upwards. The labor intensity is high, the work efficiency is low, and the drilling depth and verticality are not easy to control. In addition, the workman's operating height is generally greater than 2m, which has potential safety hazards, and the danger is even greater if drilling holes on the floor side. The drilling device made of steel pipe pole...

AI Technical Summary

Problems solved by technology

At present, the traditional construction technology is manually operated by people climbing on the ladder, and the arms are forced upwards. The labor intensity is high, the work efficiency is low, and the drilling depth and verticality are not easy to control.

In addition, the operating height of workers is generally greater than 2m, which has potential safety hazards. If drilling holes on the side of the floor is more dangerous

The drilling device made of steel pipe poles that appeared later was heavy and difficult to transport between floors, and the verticality of the drilling was greatly affected by the flatness of the ground.
