A damage detection method for floor slab thickness

Abstract

The invention discloses a damage detection method for the thickness of a floor slab, which comprises a transparent glass cylinder and a floor slab, the transparent glass cylinder has a detection rod plugged into the inside of the transparent glass cylinder, and a sliding sliding rod is sleeved on the outside of the transparent glass cylinder. shaft, the outer surface of the sliding shaft is fixedly connected with an upper positioning rod, one side of the sliding shaft is provided with a fixing bolt, and the bottom end of the detection rod is fixedly connected with a bottom shaft. The damage detection method for the thickness of the floor slab improves the measurement of the damage method measuring device for detecting the thickness of the floor slab more accurately, is convenient to use, simple to operate, saves time and effort, and the damage method measuring device for detecting the thickness of the floor slab only needs One-person operation can complete the measurement, which can improve the efficiency of measuring floor thickness by using the damage method and reduce personnel operations. It is convenient and efficient, and easy to carry. Compared with the previous two-person operation, it saves manpower and can avoid the unevenness of the formwork joints. error, the prior art is more accurate.

Description

technical field [0001] The invention relates to the technical field of floor thickness measurement, in particular to a damage detection method for floor thickness. Background technique [0002] The thickness of the slab plays a very important role in the safety of the engineering structure. The increase or decrease of the thickness of the slab will cause the deflection of the center of the slab to increase and the bearing capacity to decrease. This factor is one of the main reasons for the cracking of the floor. The reduced thickness of the floor slab also brings a series of problems such as sound insulation, heat insulation, and waterproof. In addition, the floor slab also plays a very important role in resisting the lateral displacement of the building during earthquakes. When the damage method is used to assist in measuring the thickness of the floor slab, the current method: first use an electric drill to drill a through hole of 8-10mm in the floor, and then two people w...

Problems solved by technology

Solve the problem of using an electric drill to drill a through hole of 8-10mm in the floor, and then two people work together. First, one person inserts an iron rod into the drill hole upstairs, while the other person supports it on the roof downstairs, and finally uses the positioning steel sheet on the iron rod. Use a scale to measure after marking the position. The measured data has large errors, the tool size is large, it is not easy to carry, there are many working procedures, and the accuracy is low. At least 2 people are required to work together. It is inconvenient for the two parties to communicate across the floor, and the operation is laborious. time consuming problem
