[0002] Building safety testing is a comprehensive inspection and assessment of the building's structure, equipment, materials, environment, etc. to ensure the building's safety and reliability. For building floors, thickness gauges are used to test the floor slabs, and ultrasonic thickness gauges are one of the most commonly used types.

[0003] After searching, the patent number is CN218034939U, and the name is a utility model of a floor thickness gauge, including a bottom box. Through research and analysis, it is found that although it can be conveniently adjusted according to floors of different thicknesses, it still has the following disadvantages to a certain extent.

[0004] For example, the device needs to place the receiver above the floor and the detector above the floor. This method requires the floor to be in an empty state. In actual application, the detection convenience is generally general, and it does not have the function of rapid positioning. During the detection process, the staff must always maintain the flatness and stability of the equipment installation, which has certain limitations. In order to solve the above technical problems, we have designed a floor thickness gauge with a rapid positioning function for building safety detection. Utility Model Content

[0024] See also Figure 3 and Figure 4 The bottom of the guide rod 402 is fixedly connected with an auxiliary block 408, and the bottom of the auxiliary block 408 is fixedly installed with a vacuum suction cup 407;

[0025] See also Figure 3 and Figure 4 A drainage airway 406 is provided on the top of the inner cavity of the vacuum suction cup 407, and a small vacuum generator 405 is fixedly installed on the surface of the vacuum suction cup 407 and at the outer end of the drainage airway 406;

[0026] See also Figure 3 and Figure 4 , the top of the spring 404 is fixedly connected to the bottom of the fixed block 403, and the bottom of the spring 404 is fixedly connected to the top of the auxiliary block 408;

[0027] See also Figure 2 and Figure 3, the bottom of the left and right sides of the controller 1 are fixedly installed with anti-sliding blocks 2, and the number of negative pressure positioning components 4 is three;

[0028] The detection signals of the ultrasonic probe 7 and the pressure sensor 9 are transmitted to the controller 1 and displayed numerically on the display screen 6 to facilitate observation by the staff;

[0029] By providing the anti-sliding block 2, the contact friction can be increased when the staff holds the controller 1, so as to achieve the anti-slip protection effect. By providing the connecting column 3 and the arc groove 8, it is convenient for the staff to hold and adjust the position of the ultrasonic probe 7 well.

[0030] By providing the guide hole 401 and the guide rod 402, a positioning and guiding function can be achieved, so that the guide rod 402 can stably move up and down. By providing the fixing block 403, it can be fixedly installed on the outer ring of the fixing sleeve 10 to form a plurality of negative pressure positioning components 4, thereby improving the positioning and supporting stability of the connecting column 3.

[0031] By setting the spring 404, it can play the role of elastic support and provide the auxiliary block 408 with an automatic reset force. By setting the small vacuum generator 405 and the drainage airway 406, when the small vacuum generator 405 is in the working state, the drainage airway 406 can lead out the gas in the vacuum suction cup 407, so that the vacuum suction cup 407 forms a negative pressure state.

[0032] By setting a transmission cable 5, the connection column 3 can be connected to the controller 1, the position of the connection column 3 can be conveniently adjusted, and the detection signals of the pressure sensor 9 and the ultrasonic probe 7 are transmitted to the controller 1. By setting a display screen 6, the detection signals of the ultrasonic probe 7 and the pressure sensor 9 can be displayed in real time;

[0033] In practical applications, this equipment is well suited for floors with flat and smooth surfaces, such as reinforced concrete floor slabs, steel floor slabs and wooden floor slabs.

[0034] When in use, all components are in the initial installation state, the preset pressure sensor 9 detects the pressure value, the staff holds the controller 1, and puts the finger in the arc groove 8, pinches the connecting column 3, and makes the connecting column 3 gradually move down. In this process, the bottom of the vacuum suction cup 407 first fits with the floor slab, and as the connecting column 3 moves down, the auxiliary block 408 moves up synchronously. Under the action of the guide rod 402 and the guide hole 401, the displacement stability of the auxiliary block 408 is guaranteed, and the spring 404 is compressed until the ultrasonic probe 7 fits with the floor slab. However, since the staff needs to overcome the spring 404, the auxiliary block 408 is pressed against the floor slab. In order to provide elasticity, the connecting column 3 needs to be pinched with force, wherein the pinching pressure is detected by the pressure sensor 9. When the pinching pressure exceeds the preset pressure, the controller 1 receives a signal from the pressure sensor 9 and automatically controls the small vacuum generator 405 to work. With the cooperation of the drainage airway 406, the vacuum suction cup 407 tightly adsorbs the floor slab to ensure the stability of the position of the connecting column 3 and the ultrasonic probe 7. At this time, the staff does not need to support the connecting column 3 again, and the ultrasonic probe 7 can be stably placed to measure the thickness of the floor slab, and the detection value is displayed on the display screen 6.

[0035] In summary: the floor thickness gauge with rapid positioning function for building safety inspection solves the problem that the equipment requires the floor to be in a vacant state, the detection convenience is general in actual application, and it does not have the function of rapid positioning. During the detection process, the staff must always maintain the flatness and stability of the equipment installation by setting a controller 1, a connecting column 3, a negative pressure positioning component 4, a transmission cable 5, a display screen 6, an ultrasonic probe 7, a pressure sensor 9 and a fixing sleeve 10.
