Description

Technical Field

[0001] The utility model relates to the technical field of assembled buildings, in particular to an internal detection device for assembled building component connectors. Background Art

[0002] Prefabricated buildings are buildings assembled on site with prefabricated components. Compared with traditional construction methods, prefabricated buildings are fast to build, less restricted by climatic conditions and save labor. Its characteristics are "building blocks" and "producing" houses on assembly lines. Although the traditional reinforced concrete cast-in-place technology, also known as wet operation, has made great contributions to the rapid development of urban and rural construction, its drawbacks are becoming increasingly prominent, such as serious waste of steel and cement; excessive water consumption; poor site environment and other problems. Therefore, changing the traditional construction method and developing prefabricated buildings is also a demand for energy conservation and environmental protection. In prefabricated buildings, since the prefabricated components are prefabricated in the factory, the quality of the prefabricated components can be well guaranteed. The safety of the prefabricated structure mainly depends on the connection between these components and the surrounding components. The earthquake damage survey of each major earthquake found that in the overall collapsed buildings, the prefabricated beams and columns were less damaged, and the main cause of the collapse was the damage to the connection between the components in the frame structure.

[0003] The Chinese utility model patent with the publication number CN218036586U discloses an internal detection device for prefabricated building component connectors, which relates to the field of prefabricated building engineering technology, including a frame, a second clamping seat is fixed at the bottom of the inner cavity of the frame, a sleeve body is arranged at the top of the second clamping seat, both ends of the top of the frame are penetrated by movable rods, the tops of the two groups of movable rods are extended out of the frame, the bottoms of the two groups of movable rods are installed with a first clamping seat, and the outer walls of the two groups of movable rods are sleeved with a reset spring, which is located between the top of the first clamping seat and the inner top wall of the frame. The application can adjust the spacing between the first clamping seat and the second clamping seat through the coordinated arrangement of the frame, the first clamping seat, the second clamping seat, the movable rod and the reset spring, so as to facilitate the placement of the sleeve body between the first clamping seat and the second clamping seat for fixed clamping, and try to avoid the sleeve body from rolling during detection, thereby improving the detection accuracy of the device.

[0004] However, the above patent still has the following shortcomings during actual use: the first clamping seat and the second clamping seat of the patent fix the sleeve body, but since the first clamping seat and the second clamping seat cannot move horizontally, when the length of the sleeve body is too long, the first clamping seat and the second clamping seat can only clamp the middle part of the sleeve body, and the clamping effect is not stable enough, which affects the detection work.
