Description

Technical Field

[0001] This utility model relates to the field of concrete construction technology, specifically a portable concrete finishing and covering device. Background Technology

[0002] In construction engineering, newly poured concrete needs to be finished and covered with a film to ensure the smoothness of the concrete surface and reduce cracking. In the traditional process, workers need to use trowels and other finishing tools to manually smooth the concrete surface, and after initial setting, several workers work together to unfold a plastic film to cover it.

[0003] However, applying the film after finishing the surface can easily damage the incompletely solidified concrete surface, thus affecting the final appearance quality of the concrete. Furthermore, finishing the concrete surface before applying the film will consume a longer construction time and easily reduce construction efficiency. Utility Model Content

[0004] The purpose of this utility model is to provide a portable concrete finishing and film covering device. Through the structural design of the finishing plate, adjustment components and fixing parts, the concrete finishing and film covering can be integrated into one operation, which solves the problem that film covering after finishing is easy to damage the concrete surface that has not been fully solidified.

[0005] This utility model is achieved through the following technical solution:

[0006] This utility model is a portable concrete finishing and film covering device, including a finishing plate, a U-shaped frame on the finishing plate, an adjustment component at the top of the U-shaped frame, and two fixing parts on the adjustment component. The fixing parts include a movable seat, a T-shaped shaft rotatably mounted on the movable seat, a fixed cone at one end of the T-shaped shaft, and a film roll between the two fixed cones.

[0007] Furthermore, two inclined supports are provided on the top side of the U-shaped frame, and one end of each inclined support is provided with a through hole, with a guide roller rotating between the two through holes.

[0008] Furthermore, a through groove is provided on the movable seat, and a bearing is fitted in the through groove. The outer surface of the end of the T-shaped shaft away from the fixed cone is fitted with the inner ring of the bearing.

[0009] Furthermore, the outer surface of the fixed cone is uniformly provided with anti-slip protrusions, which are elastic rubber blocks.

[0010] Furthermore, the adjustment assembly includes a fixed plate with a rectangular groove. Two circular grooves are formed within the rectangular groove, and bearings are fitted into the circular grooves. A bidirectional screw is fitted between the inner rings of the two bearings. One end of the bidirectional screw passes through the circular groove to the outside of the fixed plate, and a turntable is provided at one end of the bidirectional screw. Two drive blocks are threaded onto the outer surface of the bidirectional screw, and one end of each drive block is connected to the surface of two movable seats, which are fitted with the fixed plate.

[0011] Furthermore, handrails are provided on the finishing plate.

[0012] This utility model has the following beneficial effects:

[0013] 1. This utility model, through the structural design of a finishing plate, adjusting components, and fixing parts, allows the finishing plate to slide on the concrete surface by pulling it with a handle. This causes the smooth arc surface at the bottom of the finishing plate to grind the concrete surface. As the finishing plate moves, the film on the film roll is released and guided by the rotation of the guide roller to adhere to the already finished and smoothed concrete surface. This enables integrated operation of concrete finishing and film covering, effectively improving the appearance quality and surface smoothness of the concrete, simplifying the construction process, shortening the operation time, and making the structure simple, easy to carry and use, thus greatly improving construction efficiency.

[0014] 2. This utility model, through the structural design of the adjustment components and fixing parts, drives the bidirectional screw to rotate within the fixing plate by rotating the turntable, causing the two fixed cones to move closer to each other and cooperate with the inner rings at both ends of the film roll, thereby realizing the installation and fixing of film rolls of different widths. This allows for the installation and fixing of film rolls of different widths, effectively improving the applicability of the device, facilitating the installation and use of film rolls, and enhancing construction convenience.

[0015] Of course, any product implementing this utility model does not necessarily need to achieve all of the advantages described above at the same time. Attached Figure Description

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0022] Please see Figure 1-4 This utility model provides a technical solution: a portable concrete finishing and covering device, including a finishing plate 1, the bottom of the finishing plate 1 is provided with a smooth arc surface, which can improve the finishing and smoothing effect of the finishing plate 1 on the concrete, the finishing plate 1 is provided with a handrail 8, which facilitates the pushing and pulling of the device, the finishing plate 1 is provided with a U-shaped frame 2, the top of the U-shaped frame 2 is provided with an adjustment component 3, and the adjustment component 3 is fitted with two fixing parts 4.

[0023] The fixing component 4 includes a movable seat 401, on which a T-shaped shaft 402 is rotatably mounted. A through groove is provided on the movable seat 401, and a bearing is fitted in the through groove. The outer surface of the end of the T-shaped shaft 402 away from the fixed cone 403 is fitted with the inner ring of the bearing, which can ensure the rotation effect of the T-shaped shaft 402 on the movable seat 401 and realize the release of the film on the film roll 5. A fixed cone 403 is provided at one end of the T-shaped shaft 402. The outer surface of the fixed cone 403 is evenly provided with anti-slip protrusions, which are elastic rubber blocks, to ensure the fixing effect of both ends of the film roll 5. The film roll 5 is fitted between the two fixed cones 403. Two inclined supports 6 are provided on the top side of the U-shaped frame 2. One end of each of the two inclined supports 6 is provided with a through hole. A guide roller 7 is rotatably fitted between the two through holes, which can guide the film released from the film roll 5 and ensure that the film can adhere to the concrete surface after finishing.

[0024] In use, the device is moved to the concrete pouring area. The film roll 5 is installed and fixed between the two fixed cones 403 by adjusting the component 3. Then, the film on the film roll 5 is pulled out and one end of the stretched film is passed through the bottom of the guide roller 7 so that the upper surface of the film on the film roll 5 contacts the bottom surface of the guide roller 7. Then, the bottom surface of one end of the film is attached to the concrete surface. Then, the finishing plate 1 is pulled by the handle 8 and slid on the concrete surface so that the smooth arc surface set at the bottom of the finishing plate 1 is ground flat on the concrete surface. As the finishing plate 1 moves, the film roll 5 rotates between the two fixed cones 403 through the corresponding T-shaped shaft 402. The film on the film roll 5 is released with the movement of the finishing plate 1 and is attached to the already finished and smoothed concrete surface by the rotation of the guide roller 7, thereby realizing the integrated operation of concrete finishing and film covering.

[0025] The adjusting assembly 3 includes a fixed plate 301, on which a rectangular groove 3011 is formed. Two circular grooves are formed in the rectangular groove 3011, and bearings are fitted in the circular grooves. A bidirectional screw 302 is fitted between the inner rings of the two bearings, which facilitates the rotation of the bidirectional screw 302 in the rectangular groove 3011. One end of the bidirectional screw 302 passes through the circular groove to the outside of the fixed plate 301. A turntable 3021 is provided at one end of the bidirectional screw 302, which facilitates the rotation of the bidirectional screw 302. Two drive blocks 303 are threadedly fitted on the outer surface of the bidirectional screw 302. One end of the two drive blocks 303 is connected to the surface of two movable seats 401 respectively. The movable seats 401 cooperate with the fixed plate 301, which facilitates the stable opposite movement of the two movable seats 401.

[0026] When it is necessary to use the film roll 5 to cover concrete, place the film roll 5 of appropriate width horizontally between two fixed cones 403 and keep the inner rings at both ends of the film roll 5 aligned with the two fixed cones 403. Then, by rotating the turntable 3021, the bidirectional screw 302 is driven to rotate in the fixed plate 301, so that the two driving blocks 303 slide towards each other in the rectangular groove 3011, so that the two movable seats 401 move closer to each other, thereby driving the two fixed cones 403 to move closer to each other and cooperate with the inner rings at both ends of the film roll 5. Through the anti-slip protrusions on the outer arc surface of the fixed cones 403, the inner rings at both ends of the film roll 5 are stably fitted on the surface of the corresponding fixed cones 403, thereby realizing the installation and fixing of film rolls 5 of different widths.
