AI Technical Summary

Technical Problem

In existing technologies, when testing external wall insulation materials on-site, the testing instruments are directly attached to the surface of the external wall, which can easily generate lateral forces parallel to the bonding surface, resulting in inaccurate test results. Furthermore, the work efficiency is low due to the unevenness of the contact surface of the external wall.

Method used

A reaction plate for on-site testing of tensile bond strength is designed, which uses two resistance plates and a telescopic adapter mechanism. The L-shaped clamp is stably attached to the external wall insulation material to avoid the influence of lateral forces. The telescopic adapter mechanism is used to adapt to different distances to ensure the stability of the test.

Benefits of technology

This approach achieves accuracy and stability in test results, avoids the influence of lateral forces, and improves test efficiency and data reliability.

Abstract

A counter-force plate for field detection of tensile bonding strength belongs to the technical field of external wall insulation board bonding strength detection auxiliary equipment and comprises two resistance plates, a telescopic switching mechanism is mounted between the two resistance plates, L-shaped clamping plates are fixedly mounted on the lower surfaces of the resistance plates in a front-back symmetry manner, and the four L-shaped clamping plates are oppositely arranged. In practical application, the anti-blocking plate can replace an external wall thermal insulation material to be in contact with a frame body of a drawing instrument, lateral force parallel to a bonding surface can be prevented from being generated in the whole detection process, and it is ensured that the accuracy of a detection result is not affected. Besides, through cooperative cooperation of the telescopic switching mechanism and the four L-shaped clamping plates, stable attachment of the resistance plate and the external wall thermal insulation material can be achieved, so that the stability of the resistance plate during detection is ensured, and the detection effect is ensured.
