Perpendicularity measuring device and method of telescopic hack lever plumb bob

Abstract

The invention discloses a perpendicularity measuring device and method of a telescopic hack lever plumb bob. The perpendicularity measuring device the telescopic hack lever plumb bob comprises a base, a telescopic rod and a plumb bob, a winder is arranged on the telescopic rod, scales are arranged in the length direction of the telescopic rod, the lower end of the telescopic rod is connected to the base, the upper end of the telescopic rod is provided with a transverse rod perpendicular to the telescopic rod, a pulley set is arranged on the transverse rod, a track and a graduated scale are arranged in the length direction on the transverse rod, the pulley set is arranged on the track and can move along the track, the plumb bob is connected to one end of a string and is freely hung downward, and the other end of the string is wound around a fixed pulley set, routed along the telescopic rod and connected to the winder. The perpendicularity measuring device of the telescopic hack lever plumb bob is simple in structure and convenient to operate, the measurement of the perpendicularity can be finished at the bottom of a building component, safety hidden dangers are sharply reduced, the detection precision is improved, and the device can be applicable to measurement of different heights.

Description

technical field [0001] The invention relates to the technical field of building construction, in particular to a verticality measuring device and method for a telescopic mast erecting hammer. Background technique [0002] In the process of building construction, from the foundation to the positive and negative zero to the upper layer of the structure, the verticality of the columns and walls is usually checked and controlled in the process, and the line hammer is generally used for manual measurement. During the measurement, because the hand is easy to tremble, Eyes are too close to the line and other factors, resulting in a large error in the measured verticality, which leads to rework and repair in the later stage. Contents of the invention [0003] The technical problem to be solved by the present invention is to provide a verticality measuring device and method for a telescopic mast erecting hammer in view of the above-mentioned defects in the prior art. The measureme...
