Description

Technical Field

[0001] This utility model relates to the field of building functional technology, and in particular to a mechanical performance testing device for precast floor slabs. Background Technology

[0002] Precast floor slabs are floor slab components that are prefabricated in a factory and then transported to the construction site for installation. Compared with traditional cast-in-place floor slabs, precast floor slabs have advantages such as high production efficiency, fast construction speed, and stable quality, and are therefore widely used in modern buildings. The mechanical properties of precast floor slabs directly affect the overall safety and service life of the building. Therefore, after the precast floor slabs are processed, their mechanical properties need to be tested, which typically includes testing the load-bearing capacity, flexural strength, and shear strength of the precast floor slabs. When testing the load-bearing capacity of precast floor slabs, pressure is usually applied to the top of the precast floor slab. The load is gradually increased, and the deformation and cracking of the precast floor slab are observed as a basis for assessing its load-bearing capacity. However, during the load-bearing capacity test, the precast floor slab will crack, which will generate some debris or particles. When the current testing equipment tests the precast floor slab, it is mostly exposed to the outside. When the precast floor slab deforms and cracks, the debris is easy to fly outside, which not only pollutes the environment but may also cause injury to nearby people. At the same time, the debris after the test is inconvenient to clean up. When removing the precast floor slab or replacing it with a new one, it is easy to cause injury to the workers. Utility Model Content

[0019] To better understand the technical content of this utility model, a specific embodiment is provided below, and the utility model will be further described in conjunction with the accompanying drawings.

[0020] See Figures 1 to 2This utility model provides a mechanical performance testing device for precast floor slabs, comprising a base plate 1, a support column 2, a top plate 3, a connecting rod 4, and a testing mechanism.

The testing mechanism includes a first hydraulic rod 5, a transparent cover 6, a second hydraulic rod 7, a load plate 8, a fan 9, a dust suction head 10, a dust pipe 11, an air pump 12, and a dust collection box 13. The first hydraulic rod 5 is disposed on the bottom surface of the top plate 3, and its output... The shaft is connected to the top surface of the transparent cover 6. The bottom of the transparent cover 6 is open and located above the support column 2. The second hydraulic rod 7 is set on the inner top surface of the transparent cover 6, and its output shaft is connected to the top surface of the load plate 8. The fan 9 is embedded in the side wall of the transparent cover 6. The dust suction head 10 is set on the inner side wall of the transparent cover 6 and is opposite to the fan 9. The air pump 12 and the dust collection box 13 are set on the outer wall of the transparent cover 6. The dust pipe 11 connects the dust suction head 10 and one end of the air pump 12. The other end of the air pump 12 is connected to the inside of the dust collection box 13.

[0021] Support columns 2 are installed on the upper surface of the base plate 1. The support columns 2 can support the precast floor slab. After the precast floor slab is placed, the first hydraulic rod 5 is activated. The first hydraulic rod 5 can drive the transparent cover 6 to descend and cover the outside of the precast floor slab. Then the second hydraulic rod 7 can drive the load plate 8 to descend. The load plate 8 can contact the top surface of the precast floor slab and provide vertical load to the precast floor slab. During the inspection process, the precast floor slab will deform and crack. The debris in the cracking process can be blocked by the transparent cover 6 to prevent it from splashing and polluting the environment and hitting nearby people. The transparent cover 6 can be used by staff to observe the internal inspection situation so as to control the inspection progress at any time. The first hydraulic rod 5 and the second hydraulic rod 7 are driven by hydraulic cylinders and hydraulic pumps.

[0022] After the precast floor slab is inspected, debris and dust will accumulate on the base slab 1. At this time, the air pump 12 and the fan 9 can be turned on. The fan 9 can blow the debris and dust on the base slab 1 toward the dust suction head 10. Then the air pump 12 can suck the dust and debris into the dust head and transport it through the dust pipe 11 to the dust collection box 13 for collection, so that there will not be too much dust and debris on the base slab 1. After cleaning, the first hydraulic rod 5 can drive the transparent cover 6 to move upward, so that the staff can replace the precast floor slab and avoid the dust and debris on the base slab 1 from affecting the handling of the precast floor slab.

[0023] Preferably, the top surface of the base plate 1 is provided with a rectangular annular groove 14, and the side wall of the transparent cover 6 is located above the rectangular annular groove 14.

[0026] During the descent of the transparent cover 6, the positioning plate 15 will first contact the top surface of the precast floor slab. As the transparent cover 6 continues to descend, the compression spring 16 will be compressed. The positioning plate 15 can achieve multi-point positioning and fixing of the precast floor slab, while the pad 17 can prevent the positioning plate 15 from sliding when it contacts the precast floor slab through several anti-slip protrusions 18 set on the bottom surface.

[0028] When the positioning plate 15 moves upward in contact with the precast floor slab or moves downward under the push of the compression spring 16, the limiting rod 19 can pass through the through hole 20. The limiting rod 19 can be limited through the through hole 20 to ensure that the movement of the positioning plate 15 will not deviate.

[0029] Preferably, the detection mechanism further includes an electric slide 21, a support rod 22, and a cleaning brush 23. The electric slide 21 is mounted on the side wall of the support column 2, and its mover is connected to one end of the support rod 22. The cleaning brush 23 is mounted on the bottom surface of the support rod 22.

[0030] After the test is completed, the electric slide 21 can move the support rod 22. The cleaning brush 23 can clean the dust and debris on the base plate 1, thereby pushing the debris to one side of the vacuum head 10 so that the vacuum head 10 can completely collect the dust and debris.

[0031] Preferably, the testing mechanism further includes an electric turntable 24, which is disposed on the moving side wall of the electric slide table 21, and its rotation surface is connected to one end of the bearing rod 22.

[0032] The electric turntable 24 can drive the support rod 22 to rotate, thereby adjusting the cleaning brush 23 to face upwards or downwards. When the fan 9 blows dust and debris, the cleaning brush 23 can be set to face upwards to avoid affecting the flow of air.

[0033] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
