[0002] A basement refers to a room whose floor height is lower than the outdoor ground plane by more than half of the clear height of the room. Multi-story and high-rise buildings require deeper foundations. To make use of this height, basements are built under the ground floor of buildings, which can not only increase the usable area but also save the backfill soil in the room center, and is relatively economical. Building a basement under the ground floor of a house can improve the efficiency of building land use. Some high-rise buildings have a very large buried depth of the foundation. Making full use of this depth to build a basement has excellent economic and usage effects. Basements are classified by function into ordinary basements and air-raid shelters, and by structural materials into brick wall structures and concrete structure basements. By structural form, there are full basements and semi-basements. In order to better protect the ground plane of the basement and prevent water seepage and leakage caused by wear of the ground plane of the basement, it is necessary to lay a wear-resistant layer on the ground plane of the basement.

The rotating connection is fixed to the bottom end of the screw 41. The resisting roller 44 is fixed to the bottom end of the fixing frame 43.

[0030] The working principle of the basement wear-resistant floor construction device provided by the present utility model is as follows:

[0031] When in use, first, a sufficient amount of emery is introduced into the storage bin 63 through the feed inlet 22 for storage. Then, the device is moved to the concrete in the initial setting stage laid in the basement. The motor 32 is connected to an external power source. By operating the controller 51 on the handle 1, the motor 32 drives the grinding disc 33 to rotate, and the grinding disc 33 grinds on the surface of the concrete in the initial setting stage. Then, by rotating the screw rod 41, the screw rod 41 is driven to push the fixed frame 43 downward, so that the abutting roller 44 squeezes the conveyor belt 71 to deform downward. At the same time, the conveyor belt 71 squeezes the limiting roller 81 to compress the spring 82, so that the bottom end of the conveyor belt 71 is squeezed to abut against the surface of the concrete in the initial setting stage. Then, by pulling the handle 1, the device moves through the rollers 24 installed at the bottom end. The rotation of the rollers 24 drives the rotating shaft 25 to drive the gears 26 to rotate, so that the gears 26 drive the conveyor belt 71 engaged with them to rotate. The conveyor belt 71 rotates inside the housing 21 under the support of the guide roller 73 and the limiting roller 81. During the rotation, the material guiding roller 62 in contact is driven to rotate, so that the material guiding roller 62 evenly discharges the emery stored in the storage bin 63 onto the surface of the conveyor belt 71. As the conveyor belt 71 rotates, the carried emery is discharged from the opening at the bottom end of the housing 21 and scattered onto the surface of the concrete in the initial setting stage. Then, the conveyor belt 71 squeezes the emery so that it is pressed into the surface of the concrete in the initial setting stage. Subsequently, the grinding disc 33 follows the movement of the device to grind the emery pressed into the surface of the concrete in the initial setting stage to make it flat, so that the emery can be completely solidified with the concrete, and a wear-resistant layer surface is formed on the surface of the concrete. This device has the advantages of accurately controlling the amount and evenness of emery spreading on the floor surface, and then strengthening the flatness of the subsequent grinding of the wear-resistant layer.

[0032] Compared with the related technologies, the basement wear-resistant floor construction device provided by the present utility model has the following beneficial effects:

[0033] The present utility model provides a basement wear-resistant floor construction device. First, carborundum is introduced into the interior of the material guiding structure 6 through the top opening of the body structure 2. The material guiding structure 6 can store a sufficient amount of carborundum in advance. Then, the device is moved to the freshly laid concrete in the basement at the initial setting stage. By connecting the grinding structure 3 to an external power supply and then controlling the grinding structure 3 through the control structure 5, the grinding structure 3 is made to rotate against the surface of the concrete at the initial setting stage. Then, through the screw rod 41 in the rotary lifting structure 4, the lifting structure 4 is driven to move downward inside the body, thereby squeezing the transportation structure 7 to deform downward. The limiting structure 8 contracts until it touches the surface of the concrete. Then, by pulling the handle 1, the roller 24 in the body structure 2 is driven to roll on the concrete surface. The movement of the body structure 2 will drive the transportation structure 7 to rotate inside it. The rotating transportation structure 7 will drive the material guiding roller 62 in the material guiding structure 6 in contact with it to rotate, evenly discharging the carborundum stored inside it onto the surface of the transportation structure 7. Then, the rotation of the transportation structure 7 will sprinkle it onto the surface of the concrete directly below. As the device moves, the transportation structure 7 will squeeze the carborundum sprinkled on the concrete surface, causing it to sink into the interior of the concrete surface layer. Then, with the grinding and leveling of the grinding structure 3, the carborundum is completely integrated with the concrete, forming a wear-resistant layer on the surface layer of the concrete. This device has the advantages of being able to accurately control the amount and evenness of carborundum spreading on the floor surface, thereby enhancing the flatness of the subsequent grinding of the wear-resistant layer.
