[0025] In order to elaborate in detail the technical content and structural features of the anti-displacement warning device for the connecting members of the present utility model, the following further description is made in conjunction with the implementation modes and with reference to the accompanying drawings. Embodiment 1

[0026] As Figure 1 , 2 shown, the anti-displacement warning device for the connecting members of the present utility model includes a scaffold vertical pole 4, an embedded steel pipe 11, a connecting pipe, a stainless steel pipe 6, an acousto-optic alarm 1 and a trigger sensor 8. The scaffold vertical pole 4 and the embedded steel pipe 11 are arranged vertically in parallel and are connected by a horizontal connecting pipe. The stainless steel pipe 6 is arranged parallel to the connecting pipe. Both ends of the stainless steel pipe 6 are respectively connected to the scaffold vertical pole 4 and the embedded steel pipe 11 by steel wire bindings 5 and 10. Both ends of the connecting pipe are respectively connected to the scaffold vertical pole 4 and the embedded steel pipe 11 by fasteners 3. The stainless steel pipe 6 is arranged above the connecting pipe, with a distance of 100 mm, which can better reflect the displacement of the connecting members.

[0027] The trigger sensor 8 is arranged inside the stainless steel pipe 6 and close to the embedded steel pipe 11. The trigger sensor 8 is connected to the acousto-optic alarm 1 through an electric wire 2. The acousto-optic alarm 1 is arranged on the scaffold vertical pole 4. One end of the electric wire 2 is connected to the trigger sensor 8, and the other end extends from the inside of the stainless steel pipe 6 to the outside and is connected to the acousto-optic alarm 1. The electric wire 2 passing through the stainless steel pipe 6 has a protective effect on the circuit. The bottom of the embedded steel pipe 11 is fixed inside the concrete structure 12. Embodiment 2

[0028] The difference between this embodiment and Embodiment 1 is that it further includes a base 9 (T-shaped pipe) and a sensor contact 7. The base 9 includes a horizontally integrated sleeve 91 and a C-shaped sleeve 92. The horizontally integrated sleeve 91 is connected to the stainless steel pipe 6. The C-shaped sleeve 92 is buckled on the embedded steel pipe 11. The C-shaped sleeve 92 ensures that the base 9 and the embedded steel pipe 11 can fit better, facilitating the firm fixation of the base 9. The base 9 is also reinforced on the embedded steel pipe 11 by a steel wire binding 10.

[0029] The trigger sensor 8 is located within the lateral sleeve 91. The ends of the trigger sensor 8 and the stainless steel pipe 6 are hermetically connected to the sensor contact 7 by hot melt adhesive 13 to ensure that rainwater does not leak. A contact point 71 is provided at the other end of the sensor contact 7. The contact point 71 extends onto the embedded steel pipe 11. The diameter of the sensor contact 7 is larger than that of the stainless steel pipe 6. Both the sensor contact 7 and the contact point 71 are located within the lateral sleeve 91, which can prevent rainwater from damaging the sensor. The stainless steel pipe 6 is prohibited from having an inward slope to prevent rainwater from entering the pipe.

[0030] The induction distance of the trigger sensor 8 is 10 mm, and there is a 9-mm distance between the end of the sensor contact 7 and the sensor induction head. Therefore, when the sensor contact moves 1 mm away from the embedded steel pipe (i.e., when the outer frame deflects outward and the trigger sensor becomes loose), the sound and light alarm 1 will be triggered to give a warning.

[0031] Specifications of the trigger sensor 8: diameter 18 mm, contact induction distance 10 mm, Omron E2B-M18KS08-WZ-C1.

[0032] Specifications of the stainless steel pipe 6: inner diameter 20 mm, wall thickness 2.5 mm, and the length is set according to the coupler.

[0033] The above-disclosed are only the preferred embodiments of the present utility model. Certainly, the scope of the rights of the present utility model cannot be limited thereby. Therefore, equivalent changes made according to the claims of the present utility model still fall within the scope covered by the present utility model.
