Detection device and detection method for detecting bonding strength of wet basal plane

Abstract

The invention relates to a detection device for detecting the bonding strength of a wet base surface and a detection method thereof. The device comprises a double-arm type universal testing machine, wherein a lower end of a lower cross beam of the double-arm type universal testing machine is connected with a lifting rod for lifting a to-be-tested material , a lower end of the lifting rod is of a hollow structure, a first bolt hole is transversely formed in the lower end of the lifting rod, a fixing frame is fixedly connected with the portion, below the double-arm type universal testing machine, of a workbench, a standard-size concrete plate is installed on a lower-layer plate of the fixing frame, a test piece is formed on the concrete plate and the test piece, a drawing connector is bondedto a forming face of the test piece through high-strength bonding agent, and a second plug pin hole is formed in an upper end of a drawing rod. The device is advantaged in that the device is simple in structure, convenient to use, controllable in loading speed and force and accurate in detection.

Description

technical field [0001] The invention relates to a detection device and a detection method thereof, in particular to a detection device and a detection method thereof for detecting the bonding strength of a wet base surface. Background technique [0002] Cement-based waterproof coating is a waterproof material widely used in engineering. Its mechanism of action is to use its rich active substances to penetrate into the concrete through the water carrier, form water-insoluble crystals in the concrete, and fill the capillary channels. , so that the concrete is dense and waterproof. It belongs to the coating waterproof material of infiltration repair type. Because of its good rigidity and excellent waterproof effect, it is widely used in construction projects such as bridges, tunnels, subways, reservoirs, underground parts of industrial and civil buildings, and various underground projects. Plugging works, maintenance of all structural defects of concrete building facilities. ...

AI Technical Summary

Problems solved by technology

In the actual testing process, there are the following problems: 1. The test requires high precision and constant load stretching, which cannot be realized by ordinary simple drawing instruments; 2. The size of the test piece is large, and the concrete standard concrete slab and The size of the test piece is 400mm×200mm, small instruments cannot be erected and fixed, and the existing large-scale pull-out testing machines cannot be directly tested; 3. During the test, the connection method needs to not produce any bending stress, and ordinary equipment cannot avoid the damage caused by tilting. error

4. There is a lack of special equipment for testing the bond strength of cement-based waterproof coatings on the wet base surface in the market
