Description

Technical Field

[0001] The present invention relates to the technical field of detection, and particularly to a quality detection system for prefabricated buildings. Background Art

[0002] A prefabricated building refers to a building in which a large amount of on-site operation work in the traditional construction method is transferred to a factory. Components and fittings for construction (such as floor slabs, wall panels, stairs, balconies, etc.) are processed and manufactured in the factory, and then transported to the construction site of the building, and assembled and installed on-site through reliable connection methods.

[0003] The detection of prefabricated buildings is an important link to ensure the quality, safety and stability of buildings. After the prefabricated buildings are processed, quality detection is required. For example, anti-friction inspection is carried out on the plates to ensure subsequent assembly and use.

[0004] Currently, there is still a lack of a detection system that can conveniently perform anti-friction detection on prefabricated building plates. Instead of using the form of reciprocating linear movement to contact the plates for detection, it uses methods such as rotational friction, pressing friction, and scraping friction to rub against the plates to reflect the performance of the plates under complex friction conditions.

[0005] Therefore, in view of the above problems, a quality detection system for prefabricated buildings is proposed to solve the above problems. Summary of the Invention
