[0027] The first stress sensor 5 on the support frame 2 and the second stress sensor 6 on the support block 1 monitor the stress changes of the corresponding positions in real time and transmit the data to the control sensor 25. The control sensor 25 analyzes and processes these data. When the monitored stress value exceeds the pre-set safety threshold value, the control sensor 25 sends a signal to the alarm 24, and the alarm 24 issues an alarm to remind the construction personnel to take timely measures to avoid the occurrence of safety accidents such as concrete rupture and connection failure caused by excessive stress.

[0028] Specifically, the clamping mechanism comprises the insertion rod 14, the limiting plate 15 and the clamping assembly. The connecting block 3 and the support frame 2 are both provided with the through hole 16, the insertion rod 14 penetrates through the through hole 16, the limiting plate 15 is fixedly connected to one end of the insertion rod 14, the clamping assembly comprises the mounting block 17, the reset spring 18, the clamping block 19 and the push plate 20, the mounting block 17 is fixedly connected to the support frame 2, the mounting slot 21 is formed in the mounting block 17, the reset spring 18 is mounted in the mounting slot 21, the reset spring 18 is connected with the clamping block 19, the push plate 20 is connected with the clamping block 19, the clamping slot 22 is formed in the insertion rod 14, and one end of the clamping block 19, which is away from the push plate 20, is connected with the clamping slot 22.

[0029] The insertion rod 14 penetrates through the through holes 16 of the connecting block 3 and the support frame 2, and the insertion rod 14 preliminarily connects the two at this time. The push plate 20 is pushed, the push plate 20 drives the clamping block 19 to move in the mounting slot 21 of the mounting block 17, the reset spring 18 is compressed, and the clamping block 19 is away from the insertion rod 14.
