The directions mentioned in the utility model, such as "up", "down", "front", "back", "left", "right", "top", "bottom", etc., are only the directions of the attached drawings. Therefore, the directions used are used to explain and understand the utility model, not to limit the utility model.

[0021] As Figs. 1-3The device for detecting the compression resistance of a calcium sulfate-based active floor shown in the application comprises an oil cylinder support 1, a clamping assembly 2, a hydraulic cylinder 3 and a pressure gauge 4. The clamping assembly 2 is movably connected with the oil cylinder support 1. The hydraulic cylinder 3 is fixedly arranged on the top of the oil cylinder support 1. The pressure gauge 4 is installed on the outer side of the oil cylinder support 1. The clamping assembly 2 comprises an adjusting frame 21, an installation plate 22, a support frame 23, a limiting plate 24, a displacement sensor 25, an adjusting support knob 26, a clamping shaft 27 and a pressing plate 28. The installation plate 22 is fixedly arranged on the top of the adjusting frame 21. The support frame 23 is clamped on the top of the installation plate 22. The limiting plate 24 is fixedly arranged on the inner side of the support frame 23. The displacement sensor 25 is installed on the middle part of the installation plate 22. The adjusting support knob 26 is movably connected with the top of the displacement sensor 25. The clamping shaft 27 is fixed on the upper surface of the installation plate 22. The pressing plate 28 is movably connected with the top of the clamping shaft 27.

[0022] Specifically, the upper surface of the installation plate 22 is provided with a clamping groove matched with the bottom of the support frame 23. The bottom of the limiting plate 24 is in contact with the upper surface of the installation plate 22. The end of the pressing plate 28 is fixedly provided with a sleeve. The end sleeve of the pressing plate 28 is movably connected with the clamping shaft 27. The bottom of the pressing plate 28 is clamped on the top of the limiting plate 24. The bottom outer side of the adjusting support knob 26 is provided with a thread. The top of the displacement sensor 25 is provided with a thread hole matched therewith. The both ends of the adjusting frame 21 are provided with insertion holes. The surface of the oil cylinder support 1 is provided with limiting holes matched therewith. Limiting pin shafts are clamped in the limiting holes on the surface of the oil cylinder support 1 and the both ends of the adjusting frame 21. The end of the limiting pin shaft is clamped with a limiting clamping spring.

[0023] In this embodiment, first, the appropriate support frame 23 is selected according to the size of the active floor. The bottom of the support frame 23 is clamped into the clamping hole on the surface of the installation plate 22 until the bottom of the limiting plate 24 is in contact with the upper surface of the installation plate 22. Then, the pressing plate 28 on the surface of the clamping shaft 27 is rotated so that the pressing plate 28 is rotated through the sleeve at the end of the clamping shaft 27 until the bottom of the pressing plate 28 is pressed on the upper surface of the limiting plate 24, thereby effectively fixing the support frame 23. Then, the adjusting support knob 26 is rotated so that the top end of the adjusting support knob 26 is flush with the bottom surface of the top platform of the support frame 23. In this way, when the active floor is installed, the upper surface of the adjusting support knob 26 will be in contact with the bottom surface of the active floor.

[0024] Further, the hydraulic cylinder 3 on the top of the oil cylinder support 1 is extended so that the telescopic end thereof acts on the surface of the active floor. The pressure received by the active floor will be displayed on the pressure gauge 4 in real time, and an external display can be connected to display the pressure curve. After the floor is pressed, it will be deformed to a certain extent, and the deformation amount will be drawn into a curve and displayed on the external display through the displacement sensor 25 until the floor is broken. At this time, the pressure received by the floor will instantaneously decrease, and the reading of the displacement sensor 25 will instantaneously increase. Therefore, the critical pressure and deformation amount at which the floor is broken under pressure can be recorded, and the corresponding data can be obtained. After the detection is completed, the adjusting frame 21 can be disassembled, thereby facilitating the rapid cleaning of the surface of the installation plate 22.
