Description

Technical Field

[0001] This utility model relates to the technical field of experimental devices for concrete materials, specifically an experimental device for high-toughness fiber-reinforced concrete materials. Background Technology

[0002] High-toughness fiber-reinforced concrete is a building material with high toughness and high tensile strength, primarily enhanced by incorporating fibers into the concrete. This material absorbs more energy when subjected to external forces, thus exhibiting better ductility and durability. High-toughness fiber-reinforced concrete is often tested using the core drilling method. This method involves drilling cylindrical core samples (typically 100-150mm in diameter) from a concrete structure using a specialized drilling rig. After cutting and grinding these cores into standard specimens, their compressive strength is directly tested on a pressure testing machine.

[0003] Existing pressure testing equipment lacks convenient cleaning capabilities. During the experiment, concrete materials generate a large amount of debris, which scatters everywhere, causing significant inconvenience for the staff's cleaning work and consequently affecting the efficiency of the experiment.

Through the overall design of the support leg 21, the bottom support frame 22, the receiving frame 23 and the inner support 24, the base 1 is supported as a whole by the inner support 24 and the structure below it. During the cleaning process, the user can sweep the concrete material debris generated on the base 1 into the inner cavity of the bottom support frame 22. The concrete debris is then guided by the first inclined plate 221 and the second inclined plate 222 to the discharge through hole 223 and discharged in a unified manner, which facilitates the cleaning work. The user can place the external container at the bottom of the discharge through hole 223 in advance to collect and process the concrete debris.

[0024] like Figures 1 to 4 As shown, a stainless steel mesh plate 251 is movably connected to the inner wall of the raised frame 25, and a movable block 252 is fixedly installed on the outer wall of the stainless steel mesh plate 251. The movable block 252 is detachably connected to the back of the inner wall of the raised frame 25. A connecting cover 253 is fixedly connected to the back of the raised frame 25, and a suction fan 254 is fixedly connected to the bottom of the connecting cover 253. A clean water tank 256 is fixedly installed on the back of the support leg 21, and a connecting pipe 255 is fixedly connected to the output end of the suction fan 254. The end furthest from the suction fan 254 extends into the inner cavity of the clean water tank 256. During the experiment, the suction fan 254 can be controlled to work, drawing air through the connecting cover 253 from the front of the stainless steel mesh plate 251 to absorb the smoke and dust generated during the experiment, reducing the pollution of the smoke and dust to the internal environment of the workshop. The smoke and dust are then guided to the bottom of the inner cavity of the clean water tank 256 through the connecting pipe 255. The inner cavity of the clean water tank 256 is pre-filled with clean water, which can then be used to suppress dust and increase environmental friendliness.

[0025] like Figure 5 , Figure 6As shown, the protective mechanism 3 includes a support block 31, which is fixedly installed on the top of the top seat 12. A rotating shaft 32 is rotatably connected to the outer wall of the inner side of the support block 31. A servo motor 34 is fixedly installed on the side of the support block 31. The output shaft of the servo motor 34 is fixedly connected to the end of the rotating shaft 32. A connecting arm 33 is fixedly installed on the outer wall of the rotating shaft 32. A connecting rod 35 is fixedly installed at the end of the connecting arm 33 away from the rotating shaft 32. An arc-shaped rod 36 is fixedly installed on the front of the connecting rod 35. A curved tempered glass 37 is fixedly installed between the adjacent sides of two curved rods 36. An adhesive layer 371 is provided on the inner wall of the curved tempered glass 37, and a hydrogel film 372 is provided on the inner wall of the adhesive layer 371.

The front of the electromagnet 39 is movably connected to the back of the iron block 38. During the experiment, the curved tempered glass 37... The design can block ejected debris, ensuring the safety of workers, while also facilitating observation. The electromagnet 39 is energized to generate magnetic force that attracts the iron block 38, ensuring the curved tempered glass 37 is firmly connected to the front of the base 1. After the experiment, the electromagnet 39 is de-energized to release the magnetic connection to the iron block 38. Then, the servo motor 34 is activated, driving the rotating shaft 32 to rotate inside the support block 31. Through the transmission of the connecting arm 33, the curved tempered glass 37 can be moved, achieving automatic opening. The hydrogel membrane 372 protects the inner wall of the curved tempered glass 37 from scratches. The hydrogel membrane 372 is connected to the inner wall of the curved tempered glass 37 via an adhesive layer 371. This design allows users to replace the hydrogel membrane 372 on the inner wall of the curved tempered glass 37 when it is damaged.

[0026] This utility model provides an experimental device for high-toughness fiber concrete materials. The specific working principle is as follows: The high-toughness fiber concrete material is placed on the top of the base 1, and then the pressure testing device body 13 is used to conduct the experiment. The pressure testing device body 13 is an existing device. Pressure is applied through a hydraulic system, and the force measurement system records and displays the force value data. The operator needs to set the loading speed and target load according to the test requirements. After the test is started, the system will automatically load and record the data. When the preset load is reached, the system will automatically stop and save the data. Before the experiment, the servo motor 34 is controlled to work, driving the rotating shaft 32 to rotate inside the support block 31. Then, through the transmission of the connecting arm 33, the curved tempered glass 37 can be moved as a whole, and the curved tempered glass 37 is automatically closed. Then, the electromagnet 39 is energized and works. The electromagnet 39 can generate magnetic force to magnetically attract the iron block 38, so that the bottom of the curved tempered glass 37 is firmly connected to the front of the base 1. Then the experiment can be carried out. During the experiment, the user can observe the material through the curved tempered glass 37.
