Description

Technical Field

[0001] This utility model relates to the field of prefabricated building technology, and in particular to a non-destructive testing system for the quality of connection nodes in prefabricated buildings. Background Technology

[0002] Prefabricated construction, as an emerging construction method, boasts numerous advantages such as rapid construction speed, easy quality control, and energy conservation and environmental protection, leading to its widespread application in the modern construction industry. The quality of connection nodes in prefabricated buildings directly affects the safety and stability of the entire building structure, making their quality inspection crucial. Traditional inspection methods, including visual inspection and localized damage detection, suffer from low efficiency and an inability to accurately identify internal defects. Non-destructive testing (NDT) technology, on the other hand, can effectively inspect the internal quality of connection nodes without damaging the structure, providing a powerful tool for quality control in prefabricated buildings. Based on this, a NDT system for the quality of connection nodes in prefabricated buildings has emerged. This system integrates advanced sensor technology, data acquisition and processing technology, and intelligent analysis algorithms, enabling it to quickly and accurately detect quality problems in connection nodes, thus possessing significant engineering application value and socio-economic benefits.

[0003] A search revealed Chinese Patent Publication No. CN212228772U, which discloses a non-destructive testing system for the construction quality of large vertical joints in concrete structures. This system comprises two symmetrically arranged automatic lifting systems, an X-ray machine, a radiation receiving plate, and a related data processing system. The data processing system identifies internal defects in the sleeve. While the system is convenient and reliable, and the testing method is low-cost, slight shaking during adjustment can cause minor changes in the position of the detector collecting data, leading to signal deviations and affecting the judgment of internal defects in the connection joint.

[0046] Please see the appendix Figure 1 Appendix Figure 2 and attached Figure 5 The support plate 202 has a mounting base 18 fixedly connected to the top rear end of the right side, and a lighting lamp 19 fixedly connected to the top of the mounting base 18. An X-ray machine 12 is mounted on the top of the mounting plate 3. A knob 13 is fixedly connected to the front side of the threaded rod 9.

Finally, the L-shaped plate 4 is moved to fix and limit the height of the detector. Then, the sliding rod 7 is engaged with the inner wall of the corresponding positioning hole 5 to achieve the fixing effect. The multiple fixing effects can avoid shaking during detection and adjustment, and ensure that the detector can stably collect data in a fixed position, making the X-ray detection data accurate and reliable.

At the same time, it can adapt to detectors of different specifications, improve the versatility of the detection system, and reduce the cost of replacing different mounting devices due to different detector specifications.

[0049] The motor 204 drives the gear 205 to rotate, and the rotation of the gear 205 causes the connecting plate 207 to move up and down. The movement of the connecting plate 207 causes the support plate 1 to be adjusted, thereby enabling the detection of connection nodes at different locations. Whether the connection node is located on the ground floor, high floor, or in a special structural part of the building, it can reach the detection position, improving the versatility and applicability of the detection system and meeting diverse detection needs.
