Description

Technical Field

[0001] The utility model relates to an automatic leveling and rough surface treatment system for a cast-in-place concrete floor slab surface, belonging to the technical field of building construction. Background Art

[0002] During the construction of a house, leveling and roughening of the cast-in-place concrete floor slab surface are essential and important steps in completing the entire construction.

[0003] Traditional surface leveling usually adopts manual leveling method, which uses a scraper to scrape the concrete according to the horizontal points. This leveling method has high technical requirements for the operator, and it is necessary to grasp the timing of leveling. If leveling is too late, the workers' operating force will not be enough, and local uneven leveling may easily occur.

[0004] Traditional surface roughening typically involves manual roughening with a brown-bristle brush or wire brush. This process also requires careful timing. Roughening during the early stages of concrete setting is prone to water secretion, resulting in poor surface finish. Roughening before final setting requires increased force, significantly impacting construction speed. Furthermore, insufficient force can compromise the finish. Therefore, manual roughening cannot meet the optimal timing for surface roughening.

[0005] In summary, the above two steps are required to complete the leveling and roughening of the concrete surface layer. The stability of the workers' operating level seriously affects the surface forming effect, and the manual construction speed is slow, and the construction speed cannot meet the operational timing of the concrete surface layer leveling and roughening. The existing technology obviously has inconveniences and defects in actual use, so it is necessary to improve it. Utility Model Content

[0006] In response to the deficiencies in the background technology, the utility model provides an automatic leveling and roughening system for cast-in-place concrete floor slab surface layers. The system can be operated after the concrete of the floor slab surface layer absorbs water, and the timing of the operation is easy to control. The system can achieve automatic leveling and automatic roughening of the surface at the same time, and the two processes are completed in one step, which significantly improves the construction speed.

[0007] In order to solve the above technical problems, the present invention adopts the following technical solutions:

[0008] The automatic leveling and roughening system for cast-in-place concrete floor slabs includes a frame with rollers at the bottom and a bracket fixedly installed above the frame. Two telescopic arms arranged side by side are fixedly installed at the ends of the bracket, and the bottom ends of the telescopic arms are connected to the seat plate through supports; a scraper plate and a wire brush are installed at the bottom of the seat plate, and a laser projection component is fixedly installed in the middle position above the seat plate; the telescopic arm includes a fixed arm and a movable arm connected in a sliding manner, and both the fixed arm and the movable arm are hollow structures. A telescopic cylinder is installed inside the fixed arm, and the telescopic cylinder provides power for the movable arm to slide along the fixed arm.

[0009] Furthermore, the scraping plate is arranged close to the roller at the bottom of the frame.

[0010] Furthermore, the top of the scraping plate is fixedly connected to the bottom of the seat plate, and a plurality of ribs are respectively provided on both sides of the connection between the scraping plate and the seat plate.

[0011] Furthermore, the wire brush is rotatably mounted on the bottom of the seat plate, the shaft heads at both ends of the wire brush are passed through the bearing seat, and the bearing seat is fixedly mounted on the bottom of the seat plate.

[0012] Furthermore, the telescopic arm is arranged in a vertical direction.

[0013] Furthermore, the fixed arm is fixedly connected to the end of the bracket.

[0014] Furthermore, the movable arm extends from the bottom end of the fixed arm, and the bottom end of the movable arm is hingedly connected to the support.

[0015] Furthermore, the tail of the telescopic cylinder is connected to the fixed arm, and the head of the telescopic cylinder is connected to the movable arm.

[0016] Furthermore, a handle is fixedly mounted on the frame.

[0017] Compared with the prior art, the present invention has the following advantages after adopting the above technical solution:

[0018] The utility model installs a scraper plate and a wire brush at the bottom of the seat plate. The scraper plate can level the surface layer of the concrete floor during the lateral movement, and the wire brush can roughen the surface layer of the concrete floor. The leveling and roughening processes are combined into one step instead of the original two processes, which significantly improves the construction speed. The seat plate is installed at the bottom of the telescopic arm, so that the height and angle of the seat plate can be adjusted. The laser projection component is installed on the seat plate, and the laser projection component can project a laser horizontal line for verification with the horizontal line measured on site, so as to ensure that the seat plate is in a horizontal state in real time, and further ensure that the scraper plate and the wire brush are in a horizontal state to prevent tilting from affecting the leveling and roughening effects.
