Horizontal adjustment type measuring device for building floor installation

Abstract

The invention provides a horizontal adjustment type measuring device for building floor installation, which relates to the technical field of measuring devices and comprises a first scale and a marking part. A mounting groove is formed in the top end face of the first ruler, a sliding groove is further formed in the top end face of the first ruler, and the sliding groove is in sliding connection with the sliding protrusion of the second ruler. Through arrangement of a cleaning block, a cleaning block B is adhered to the right end face of a second ruler, and the distance between the bottom end face of the cleaning block B and the top end face of a first ruler is 0.3 cm, so that the cleaning block B cannot erase a mark when the second ruler slides left and right, and the mark can be erased only when the cleaning block B is pressed downwards; the problems that in the prior art, if the length of a measuring ruler is not enough during measurement, individual workers do not want to move a ladder, the individual workers can stretch the hands to the maximum extent and even tilt the body to conduct measurement, and the ladder easily topples over to cause safety accidents are solved.

Description

technical field [0001] The invention relates to the technical field of measuring devices, in particular to a level-adjusting measuring device used for installation of building floor slabs. Background technique [0002] Pre-measurement is required before the floor slab is installed at the corner of the building. When measuring the outer floor slab, the construction personnel need to climb to a high place through a ladder for measurement. [0003] However, as far as the current traditional horizontal adjustment measuring device used for building floor installation is concerned, first of all, the length of the current measuring ruler is not enough, and the realization of the measurement needs to change the position many times, so when measuring at a high place, it is necessary to adjust the ladder repeatedly. The location of the ladder will affect the construction efficiency; secondly, if the length of the measuring ruler is not long enough for individual workers and they do no...

Problems solved by technology

[0003] However, as far as the current traditional level-adjusting measuring device for building floor installation is concerned, first of all, the length of the current measuring ruler is not enough. The realization of the measurement needs to change the position many times, so the ladder needs to be adjusted repeatedly when measuring at a high place. The position affects the construction efficiency; secondly, at present, if the length of the measuring ruler is not enough and the individual staff does not want to move the ladder, at this time, the individual staff will stretch their hands to the greatest extent or even tilt their bodies to measure. It is easy to cause the ladder to fall and cause a safety accident
