DETAILED DESCRIPTION

[0025] In order to make the technical problems, technical solutions and beneficial effects to be solved by the present invention clearer and more understandable, the following is a summary of the technical problems, technical solutions and beneficial effects to be solved by the present invention. Figure 1-8 It should be understood that the specific embodiments described herein are only used to explain the present invention and are not used to limit the present invention.

[0026] Reference Figure 1 , Figure 2 and Figure 3, A displacement monitoring and warning device for a high-rise corridor control platform. The control platform 1 is horizontally arranged between the first building 2 and the second building 3. A frame column 21 is vertically arranged in the first building 2. One side of the control platform 1 is fixed on the frame column 21 of the first building 2. The monitoring and warning device 4 is fixedly arranged on the shear wall 31 of the second building 3. The other side of the control platform 1 is arranged on the monitoring and warning device 4. Thus, the displacement of the control platform 1 is monitored by the monitoring and warning device 4.

[0027] Refer to Figure 4-Figure 7 , The monitoring and warning device 4 includes a beam bracket 41, a hanging plate 42, a plurality of vertical displacement sensors 43 and a plurality of horizontal displacement sensors 44. The beam bracket 41 includes a concrete corbel 411 and a steel structure corbel 412. One side of the concrete corbel 411 is fixedly arranged at the shear wall 31 of the second building 3. The steel structure corbel 412 is on the side of the concrete corbel 411 away from the shear wall 31 of the second building 3. The concrete corbel 411 is composed of a plurality of horizontal bars 5, a plurality of vertical stirrups 6, a plurality of longitudinal bars 7 and a concrete layer 8. Among them, both the horizontal bars 5 and the longitudinal bars 7 are in a "U" shape, and the vertical stirrups 6 are in a "square" shape. The longitudinal bars 7 are vertically arranged so that the plane where the longitudinal bars 7 are located is a vertical plane, and the distance between adjacent two longitudinal bars 7 is kept the same. A plurality of vertical stirrups 6 are arranged inside the longitudinal bars 7 and are evenly distributed along the length direction of the longitudinal bars 7. Each vertical stirrup 6 is welded and fixed to the longitudinal bars 7. In addition, a plurality of horizontal bars 5 are evenly distributed in the vertical direction, and each horizontal bar 5 is welded and fixed to the vertical stirrups and the longitudinal bars 7. One end of a plurality of longitudinal bars 7 and horizontal bars 5 penetrates into the shear wall 31 of the second building 3. A plurality of horizontal bars 5, a plurality of vertical stirrups 6 and a plurality of longitudinal bars 7 are concreted to form a concrete layer 8. The plurality of horizontal bars 5, a plurality of vertical stirrups 6 and a plurality of longitudinal bars 7 form a three-way steel cage structure, thereby making the concrete corbel 411 have stronger structural strength. And by adding the concrete corbel 411 and the steel structure corbel 412, when the control platform 1 has excessive vertical displacement, it can bear part of the shear force of the control platform 1, increasing the structural ductility and safety margin. The structure is simple, convenient for construction, and easy to maintain and replace.

[0028] Refer to Figure 2 and Figure 7The control platform 1 includes a plurality of steel beams 11 and a plurality of horizontal supports 12. The plurality of steel beams 11 are arranged in a mesh structure, and the steel beams 11 are welded and fixed to each other. A connecting plate 13 is provided at the bottom end of each steel beam 11, and the two ends of the horizontal support 12 are fixedly connected to the two connecting plates 13, respectively, so that a "M"-shaped structure is formed between the four horizontal supports 12 and the steel beams 11 fixed to the same connecting plate 13. The setting of the connecting plate 13 increases the welding area of ​​the horizontal support 12 and enhances the connection strength between the horizontal support 12 and the steel beam 11. When fixing, one end of the steel beam 11 is fixedly connected to the frame column 21 in the first building 2, and the steel beam 11 is kept in a horizontal state. A corner brace 14 is provided at one end of the bottom of some steel beams 11. The setting of the corner brace 14 improves the stability of the installation of each steel beam 11 structure. In order to ensure that the beam support 41 can ensure the stability of the control platform 1, the width of the control platform 1 is set to "L", the width of the concrete corbel 411 is set to "A", and the relationship between the width of the control platform 1 and the width of the concrete corbel 411 satisfies 20A. <L<30A。

[0029] Reference Figure 7 and Figure 8 In the monitoring and early warning device 4, the vertical displacement sensor 43 is arranged above the steel structure bracket 412, the steel beam 11 on the side close to the second building 3 in the control platform 1 is fixedly arranged on the vertical displacement sensor 43, the horizontal displacement sensor 44 is horizontally fixedly arranged on one side of the steel structure bracket 412, and the lower hanging plate 42 is vertically arranged so that the bottom end of the lower hanging plate 42 is fixed to the horizontal displacement sensor 44, and the top end of the lower hanging plate 42 is fixed to the steel beam 11 on the side close to the second building 3 in the control platform 1.

[0030] The vertical displacement sensor 43 and the horizontal displacement sensor 44 are set with a critical value of the early warning signal. When the control platform 1 undergoes vertical displacement, the force is transmitted to the vertical displacement sensor 43. When the vertical displacement sensor 43 detects that the vertical displacement of the control platform 1 exceeds the set critical value, the vertical displacement sensor 43 will send out an early warning signal. When the control platform 1 undergoes horizontal displacement, the horizontal displacement is transmitted to the horizontal displacement sensor 44 through the lower hanging plate 42 fixedly connected thereto. When the horizontal displacement sensor 44 detects that the horizontal displacement of the control platform 1 exceeds the set critical value, the horizontal displacement sensor 44 will also send out an early warning signal. In this way, pedestrians on the corridor can gain time to escape, and at the same time, the early warning signal is transmitted to the central control console. By analyzing the displacement of the corridor and combining the structural characteristics of the corridor itself, the damage of the main structure can be inferred, which is convenient for management personnel to identify and conduct the next step of inspection and maintenance.

[0031] Reference Figure 2 and Figure 3In order to further enhance the structural strength of the control platform 1, a diagonal brace 15 is fixedly provided at the bottom end of the control platform 1, and the top end of the diagonal brace 15 is fixed to the middle position of the bottom of the control platform 1. The bottom end of the diagonal brace 15 is welded and fixed to the connection between the next layer of control platform 1 and the frame column 21. The force received by the middle position of the control platform 1 is transmitted to the frame column 21 through the diagonal brace 15, thereby enhancing the structural strength and seismic resistance of the control platform 1.

[0032] The specific implementation principle of the embodiment of the present application is as follows: according to the working conditions of different control platform 1, the alarm limit values ​​of the vertical displacement sensor 43 and the horizontal displacement sensor 44 are adjusted respectively. When the control platform 1 undergoes vertical displacement, the control platform 1 generates a force on the vertical displacement sensor 43 located at its bottom. When the vertical displacement sensor 43 detects that the amount of vertical displacement of the control platform 1 reaches the alarm limit value, the vertical displacement sensor will send out an early warning signal; when the control platform 1 undergoes horizontal displacement, the control platform 1 will transfer the amount of its horizontal displacement to the horizontal displacement sensor 44 through the lower hanging plate 42, and thus the horizontal displacement sensor 44 will also send out an early warning signal. The vertical displacement and horizontal displacement of the control platform 1 are monitored separately, thereby having a higher monitoring accuracy for the displacement monitoring of the control platform 1; when the vertical displacement sensor 43 or the horizontal displacement sensor 44 sends out an early warning signal, it can buy time for the pedestrians on the corridor to escape, and at the same time transmit the early warning signal to the central control console. By analyzing the displacement of the corridor and combining the structural characteristics of the corridor itself, the damage of the main structure can be inferred, which is convenient for the management personnel to identify and conduct the next step of detection and maintenance.

[0033] The utility model is described above by way of example in conjunction with the accompanying drawings. It is obvious that the specific implementation of the utility model is not limited to the above-mentioned method. As long as various non-substantial improvements are made using the method concept and technical solution of the utility model, or the concept and technical solution of the utility model are directly applied to other occasions without improvement, they are all protected by the utility model.
