A concrete slab thickness detector

Abstract

The invention relates to a concrete slab thickness detector, which includes a workbench, a transverse guide rail, a transverse electric slider, a mounting frame and a detection device. The workbench is symmetrically installed with transverse guide rails front and rear, and a transverse electric slide is installed slidingly on the transverse guide rail. A mounting frame is installed between the transverse electric sliders symmetrically arranged front and back, and a detection device is installed on the mounting frame, and a sliding groove is opened on the mounting frame. The mounting frame is a retractable structure up and down. Cylinder, cylinder cover, detection rod, lifting plate, reset compression spring and marking mechanism. The invention can carry out comprehensive detection on the concrete slab. When the protrusion or depression on the concrete slab is detected, the detection device will make appropriate marks on the corresponding position of the concrete slab, so that the staff can intuitively judge the type of defect and the occurrence of the defect. location for subsequent follow-up on the defect.

Description

technical field [0001] The invention relates to the construction field, in particular to a concrete slab thickness detector. Background technique [0002] Concrete slab is a slab made of reinforced concrete, which is the basic structure or component in building construction and various engineering structures. It is often used as roof, floor, platform, wall, retaining wall, foundation, floor, road surface, Pools, etc., a wide range of applications. According to the plane shape, it can be divided into square plate, circular plate and special-shaped plate. According to the force action mode of the structure, it is divided into one-way plate and two-way plate. [0003] The thickness of the concrete slab should meet the requirements of strength and rigidity, so it is necessary to detect the thickness of the concrete slab after it is formed. The existing detection equipment can be divided into two types: contact type and non-contact type. Existing equipment is used to detect squ...

Problems solved by technology

[0004] Contact thickness detection equipment usually uses inductive displacement sensors, capacitive displacement sensors, potentiometer displacement sensors, Hall displacement sensors, etc. for contact thickness measurement; contact thickness detection equipment usually uses eddy current thickness sensors, magnetic thickness sensors , ultrasonic thickness sensor, X-ray thickness sensor, etc. for non-contact thickness measurement. After the detection of these two detection equipment, because there is no clear mark on the concrete slab, the staff cannot quickly judge the defect location and defect type. Extended time for subsequent processing of concrete slabs
