Description

Cast-in-place concrete floor thickness measuring device Technical Field The utility model relates to the technical field of constructional engineering measuring equipment, in particular to a thickness measuring device for a cast-in-place concrete floor slab. Background The cast-in-place concrete is a concrete structure formed by in-situ formwork support and integral casting, and the core working procedures comprise formwork support, steel bar binding, concrete casting, curing and formwork removal, and have the advantages of strong integrity, good anti-seismic performance and the like. The thickness of the floor slab is the thickness from the floor slab surface to the floor slab bottom after the reinforced concrete floor slab is poured. In the existing floor thickness detection mode, after a detector uses an impact drill to vertically drill down through a floor at a point to be detected, a rigid plate is used for propping up the drilled hole on the next floor, so that the rigid plate is tightly attached to the bottom of the floor, and then a depth vernier caliper is used for measuring the distance between the bottom and the top of the hole. Such a detection mode is to detect the floor slab after the concrete is set. In the course of the measurement process, Therefore, we propose to design a cast-in-place concrete floor thickness measuring device.
