Description

Technical Field

[0001] The utility model relates to the technical field of steel structure detection, in particular to a deformation detection device for a steel structure of a house. Background Art

[0002] Prefabricated steel structures have been widely used in large factories, stadiums, super-high-rise buildings and other construction fields due to their light weight and simple construction. During the service of prefabricated steel structure buildings, sensors are often used to detect the stress and deformation of the steel structure, and the correspondence between the strain distribution of the steel structure and the changes in longitudinal and transverse deflections is studied. The steel structure is pressure tested by a hydraulic press, and the compressed steel structure is placed on a bracket. Data on the connection damage and transverse stress distribution of the steel structure are collected, and a steel structure connection damage diagnosis model is established based on the collected data, which can realize rapid and accurate diagnosis of steel structure damage.

[0003] After searching, a Chinese patent discloses a deformation detection device for assembled steel structures (authorization announcement number CN216869468U), including a base, a connecting plate fixedly arranged on the base, a clamping portion arranged on the connecting plate; an inspection ring slidably arranged on the connecting plate, a detection ring rotatably arranged inside the inspection ring, and a sensor arranged on the detection ring; a motor fixedly arranged on the connecting plate, wherein a lead screw is arranged at the output end of the motor, and a driving gear for driving the detection ring to rotate is arranged on the lead screw, and when the lead screw rotates, the driving gear reciprocates on the lead screw. Although this patented technology reduces the number of sensors, reduces the detection cost, and simplifies the sampling steps, it ensures the comprehensiveness and high efficiency of data collection, greatly improves the accuracy of establishing the data model, and provides more accurate data for subsequent analysis of damage diagnosis of steel structure connections.

[0004] However, the above-mentioned device still has some shortcomings in actual use. The most obvious one is that in the above-mentioned deformation detection device for prefabricated steel structures, the prefabricated steel of the I-shaped structure is clamped by telescopic rods and guide wheels, but the clamping setting of the guide wheels cannot adapt to the clamping of square and circular prefabricated steel structures of different sizes. Therefore, during the detection process, the detection results will be inaccurate due to unstable clamping, and thus the production requirements of square and circular prefabricated steel structures cannot be met, reducing the flexibility and practicality of the device.
