Abstract

The invention discloses a building crack continuous observation ruler. It includes the first and second fixing plates; the first and second fixing plates are respectively provided with fixing holes; The right end of the second fixed plate is equipped with a rigid transmission rod changing gear, the top of the rigid transmission rod changing gear is hinged to the second rigid transmission rod, and the first rigid transmission rod and the second rigid transmission rod are articulated together; The variable guide rail is installed horizontally, and the top and opposite sides of the variable guide rail are provided with variable guide rail teeth, and the variable guide rail teeth are meshed with the rigid transmission rod direction change gear; the second fixed plate is installed with a compass pointer gear through the rotation of the rotating shaft , the compass pointer gear meshes with the variable guide rail teeth, a compass is fixedly installed on the second fixed plate, the rotating shaft passes through the compass upwards and is connected with a compass pointer at the top of the rotating shaft. The invention can continuously observe the cracks.

Description

technical field [0001] The invention belongs to the field of building engineering construction and reinforcement, in particular to a continuous observation ruler for building cracks. Background technique [0002] In construction projects, there will be relatively large cracks in some ancient buildings and building components with quality problems. The existing crack observation methods generally use a ruler to measure, or use a feeler gauge to measure the crack. A straightedge is inaccurate in measuring cracks, and there is no continuity. Feeler gauges are generally suitable for smaller cracks and are not very accurate. In order to continuously observe these cracks, it is urgent to invent an observation ruler with relatively high sensitivity to solve the above-mentioned problem of observation of building cracks. SUMMARY OF THE INVENTION [0003] In order to overcome the deficiencies in the prior art, the purpose of the present invention is to provide a continuous observ...
