Technical Field

[0001] This utility model relates to the field of building construction, and in particular to a plastering device for the outer surface of a circular column. Background Technology

[0002] Building plastering is an important process in construction engineering, mainly referring to the application of mortar to the structural surfaces of walls, columns, beams, etc., to achieve a smooth, aesthetically pleasing finish and protect the structure. This work not only affects the appearance of the building but also has a direct impact on the durability and waterproofing performance of the walls.

[0003] Many unfinished houses currently have circular columns, and during renovation, the surfaces of these columns need to be completely plastered. Traditionally, cement mortar is first applied to the surface of the circular columns, and then manually smoothed using a trowel or a curved smoothing tool. This process is inconvenient, affects construction efficiency, and needs improvement. Utility Model Content

[0014] The present invention will be further described in detail below with reference to the accompanying drawings.

[0015] like Figure 1 , Figure 2 As shown, a plastering device for the outer surface of a circular column includes a pair of lifting plates 1, a plastering component 2, and a driving component 3.

[0016] like Figure 1 , Figure 2 As shown, a pair of lifting plates 1 are arranged horizontally, and a semi-circular notch 11 is provided on the inner side of the lifting plate 1. After the pair of lifting plates 1 are interlocked, the notch 11 surrounds the circular column, and the inner wall of the notch 11 is 1-2 cm away from the surface of the circular column.

[0017] like Figure 1 , Figure 2 As shown, a semi-circular rubber plate 12 is provided on the inner side of the lifting plate 1. The rubber plate 12 is located in the notch 11 and is used to abut against the surface of the circular column and to stably support the cement mortar around the circular column.

[0018] like Figure 1 , Figure 2 As shown, the plastering assembly 2 includes an installation half-cylinder 21 and a scraper 22. The installation half-cylinder 21 is semi-circularly mounted on the lifting plate 1 and interlocks with each other to surround the circular column. The scraper 22 has an L-shaped cross-section and is semi-circularly arranged inside the installation half-cylinder 21.

[0019] like Figure 1 , Figure 2 As shown, the scraper blades 22 interlock and surround the circular column, with the inner wall of the scraper blades 22 flush with the inner wall of the notch 11. The horizontal section of the scraper blades 22 is rotatably connected to the mounting half-cylinder 21, forming an annular channel between the scraper blades 22, the mounting half-cylinder 21, and the lifting plate 1.

[0020] like Figure 1 , Figure 2 As shown, a material inlet 23 is provided through the installation half-cylinder 21, and multiple elongated slurry outlets 24 are vertically arranged and spaced apart on the inner side of the scraper 22. Multiple hollow support blocks 25 are evenly distributed on the inner side of the scraper 22. The support blocks 25 abut against the inner side of the installation half-cylinder 21 to achieve stable support between the installation half-cylinder 21 and the scraper 22. A guide roller 26 is vertically rotatably connected to the side of the support block 25 facing the installation half-cylinder 21 to increase the smoothness of rotation.

[0021] like Figure 1 , Figure 2 As shown, the drive assembly 3 is used to control the rotation of the scraper 22. The drive assembly 3 includes a gear ring 31, a mounting base 32, a motor 33, and a gear 34.

[0022] like Figure 1 , Figure 2 As shown, the toothed ring 31 is disposed on the upper outer wall of the scraper plate 22, the mounting base 32 is disposed on the lifting plate 1, the motor 33 is disposed on the mounting base 32, and the gear 34 is disposed on the motor 33 and meshes with the toothed ring 31.

[0023] When plastering is required on the outer surface of the circular column, a pair of lifting plates 1 are interlocked and then fixed, with the notch 11 on the lifting plate 1 arranged in a circle around the outer wall of the circular column. The distance between the inner wall of the notch 11 and the outer wall of the circular column is then measured, ensuring that the axial direction of the notch 11 is coaxial with that of the circular column.

[0024] When the lifting plates 1 are interlocked, the lifting plates 1 also cause the mounting half-cylinders 21 to interlock as well. Then, screws are used to fix the outer walls of the pair of mounting half-cylinders 21 to form a circular ring. At the same time, the scraper plates 22 are also interlocked and surround the circular column in a ring shape. The scraper plates 22 can also rotate along the circular direction of the mounting half-cylinders 21.

[0025] Then, the lifting plate 1 is raised to the highest position of the circular column, and the pump pipe is connected to the injection port 23, so that the cement mortar can enter the annular channel formed between the scraper plate 22, the installation half cylinder 21 and the lifting plate 1 along the injection port 23. Then the cement mortar is discharged outward along the outlet 24. At the same time, under the support of the rubber plate 12, the gap between the scraper plate 22 and the circular column is slowly filled with cement mortar.

[0026] Then, the motor 33 drives the gear 34 to rotate, which in turn drives the gear ring 31 to rotate. This causes the scraper 22 to slowly rotate along the circumference of the mounting half-cylinder 21. At this time, the inner wall of the scraper 22 automatically smooths the cement mortar on the outer surface of the circular column. Subsequently, the lifting plate 1 is controlled to move downwards a certain distance to achieve automatic smoothing of the cement mortar on the surface of the circular column for the next distance, and to evenly apply the cement mortar to the outer surface of the circular column.

[0027] Therefore, by setting up a lifting plate 1 that surrounds the surface of the circular column, and setting a ring-shaped plastering component 2 on the lifting plate 1, the plastering component 2 is used to evenly rotate and apply cement mortar to the surface of the circular column, thereby achieving automatic plastering and uniform plastering operations and improving plastering efficiency.

[0028] Meanwhile, by setting an injection port 23 that can be connected to a pump pipe on the plastering component 2 and setting a grout outlet 24 on the inner side, cement mortar can be automatically injected into the inner side of the plastering component 2, thereby realizing automatic cement mortar supply and plastering operation.

[0029] The specific embodiments are merely explanations of this utility model and are not intended to limit it. After reading this specification, those skilled in the art can make modifications to these embodiments without contributing any inventive step, but such modifications are protected by patent law as long as they fall within the scope of the claims of this utility model.
