Plumb bob device for building construction measurement

Abstract

The invention discloses a plumb bob device for building construction measurement, which comprises a frame body, a winding mechanism, a shell, a limiting mechanism and a fixing mechanism, the winding mechanism is installed inside the frame body, and the shell is installed at the bottom of the frame body. The winding mechanism and the limiting mechanism are matched with each other, a handle drives adrum to rotate by rotating a rotating shaft, so that a pendant rope is wound on the surface of the drum, a pendant head is accommodated in the shell; then a limiting cover is rotated through a knob,the pendant head is limited by the limiting sleeve, a plumb bob is convenient to store; transportation and carrying processes are relatively convenient; meanwhile, during perpendicularity measurement,through mutual cooperation of a baffle and a fixing plate in the fixing mechanism, the distance between the baffle and the fixing plate can be adjusted according to the thickness of the wall, the plumb bob can be fixed conveniently, and compared with the mode that the plumb bob is held by hand for measurement, the measurement precision of the plumb bob is improved, and great convenience is brought to construction work.

Description

technical field [0001] The invention relates to the technical field of building construction, in particular to a line drop device for building construction measurement. Background technique [0002] Line pendants, also called plumb weights, are mainly used to measure the verticality of objects. Line pendants are needed in the construction process. For example, the application number: 201820662254.3 is a construction line pendant, including a cone, a line body and The water collecting box has a water collecting chamber in the middle of the water collecting chamber, a piston is installed in the water collecting chamber, a draw rod is arranged at the bottom of the piston, and a wire groove is arranged at the bottom extension end of the draw rod, and the top of the wire body is installed in the In the trunking, the top of the connecting block is provided with a lifting ring, the bottom of the line body is connected with the lifting ring, and the connecting block part extends int...

Problems solved by technology

The invention adopts the effect of magnet buffering, so that the swinging cone can be fast and stable, reducing shaking, and can make the whole wire absorb water through gravity, increase the overall weight of the wire, reduce the swing of the wire when it is in use, and increase the weight of the wire at the same time. The outer diameter makes it easier to observe, but it is not convenient for storage during use, and it is inconvenient during transportation and carrying. At the same time, when measuring verticality, because the line drop is not easy to fix, it is usually hand-held The measurement accuracy is relatively low, which brings great inconvenience to the construction work. Therefore, we propose a line pendant device for building construction measurement.
