Description

Detection apparatus convenient to floor thickness detects

Technical Field

Background

In the quality detection of the construction engineering structure, the thickness of the floor slab is one of the very important indexes, and the thickness of the floor slab plays a very important role in the safety of the engineering structure, so that the thickness detection of the floor slab is one of the necessary inspection items in the quality detection of the engineering. The thickness of the floor slab refers to the vertical distance from the surface of the floor slab to the bottom surface of the floor slab after the reinforced concrete is poured. Current floor thickness testing methods generally include damage testing and non-damage testing. The damage detection method is characterized in that a percussion drill is used for drilling a floor vertically downwards at a point to be measured, and then a vernier caliper is used for measuring the distance between the bottom and the top of a hole. The conventional device mainly used for detecting the thickness of the floor slab in the non-damage detection method generally uses a floor slab thickness gauge, the floor slab thickness gauge mainly comprises a transmitting probe and a receiving probe, when the receiving probe receives an electromagnetic signal of the transmitting probe, a signal processing unit analyzes the electromagnetic signal according to the kinematic characteristics of the electromagnetic wave, and automatically calculates the distance between the transmitting probe and the receiving probe, wherein the distance is the thickness of the floor slab. However, when the floor thickness gauge is used, an operator needs to hold the receiving probe at one side of the wall and another operator needs to hold the transmitting probe at the other side of the wall for detection, and the receiving probe and the transmitting probe cannot be aligned up and down accurately and quickly due to the fact that the floor is separated, but when the floor thickness gauge is used for detection, the detection personnel on the building and under the building cannot accurately determine the position of the other side, the coarse position is determined firstly through the interphone, then the transmitting probe is fixed by the person under the building, the person on the building uses the receiving probe to move the probe back and forth in a general position range, the minimum thickness value is searched to be used as a detection value, the detection method not only has high abrasion degree on the probe, but also greatly reduces the detection efficiency, has certain error, and needs to be repositioned when the floor thickness gauge is moved to the next detection point, and the processes need to be repeated, until the detection of the whole floor is completed, when the detection is carried out, the searching and positioning of the detection point occupies more than half of the time of the whole detection process, so that the whole detection efficiency is greatly reduced.
