Floor thickness detection auxiliary device

The utility model discloses a floor thickness detection auxiliary device, belongs to the field of building construction, and solves the problem that a transmitting probe and a receiving probe of a floor thickness detector are difficult to align when a cast-in-place building floor is detected. The device comprises a strong magnet, a magnetic needle and a laser range finder, the strong magnet is located on the lower surface of a floor slab, two supports are arranged on the upper surface of the floor slab, the magnetic needle is rotationally connected to the supports, and the magnetic needle is connected with the laser range finder. A magnetic field generated by the strong magnet is utilized, so that the magnetic needle drives laser rays emitted by the laser emitter to intersect at one point, and the floor thickness detection position can be accurately determined. The device is simple in structure and convenient to install and detect, and has good practicability and economical efficiency. 本实用新型公开了一种楼板厚度检测辅助装置，属于
