Description

Technical Field

[0001] The utility model relates to the technical field of building steel structures, in particular to a detection device for building steel structures. Background Technique

[0002] Building steel structures such as steel plates need to be subjected to pressure detection. The purpose is to detect the deformation of the steel structure under a certain pressure, so as to better understand the bearing capacity of the steel structure. Here, the steel structure is a square long steel plate.

[0003] Its working principle is to place the steel plate on the platform, and use a cylinder or a hydraulic cylinder to apply pressure to the points of the steel plate, penetrate the deformation of the steel plate, and record the pressure value at this time.

[0004] However, for the pressure detection of long steel plates, the position of the steel plate needs to be continuously adjusted on the platform. Since the steel plate is relatively heavy, it is not convenient and laborious to adjust, so a new detection device for building steel structures is proposed to solve the above problems.

Next, these electrical signals will go through a series of processes, including amplification, filtering, and analog-to-digital conversion. The processed electrical signals will be transmitted to the interface of the digital display screen.
