Description

Technical Field

[0001] This utility model relates to the field of concrete construction technology, and in particular to a two-in-one tool for finishing the surface and covering with a film. Background Technology

[0002] After the concrete is poured, the concrete surface needs to be smoothed and finished. Then, a plastic film is laid on the concrete surface to prevent the water in the concrete from evaporating and to keep the concrete sufficiently moist. During this process, the concrete construction team performs concrete finishing and film covering operations to ensure the flatness of the concrete surface and maintain a certain level of humidity to facilitate the formation of crystals inside the concrete.

[0003] Existing two-in-one tools for finishing and covering concrete surfaces combine a finishing panel and a plastic film using a frame. However, the plastic film is rolled up on the surface of a film roller, while the bottom of the frame is rotatably connected to the film roller. As the finishing panel and plastic film slide across the concrete surface, concrete debris easily adheres to the connection between the frame and the film roller, causing friction and wear, or even jamming. This makes it difficult for the frame to smoothly pull the film roller to rotate and unfold the plastic film. At the same time, when the finishing panel moves with the frame to smooth and finish the concrete surface, the installation position between the finishing panel and the frame is relatively fixed, as is the distance between the finishing panel and the film roller. The position of the finishing panel on the frame surface cannot be adjusted, making it inconvenient to lift the frame to different heights to smooth and finish the concrete surface.

[0004] Therefore, a tool combining surface covering and film covering is proposed. Utility Model Content

[0005] The purpose of this invention is to solve the problem in the prior art where concrete debris easily adheres to the connection between the frame and the film roller as the receiving panel and plastic film slide across the concrete surface, causing friction and wear or even jamming at the connection, making it difficult for the frame to smoothly pull the film roller to rotate and unfold the plastic film. Therefore, this invention proposes a two-in-one tool for receiving the panel and covering the film.

[0006] To achieve the above objectives, this utility model provides the following technical solution: Design a tool that combines film gathering and covering, including a frame, a film roller rotatably mounted at the bottom of the frame, a plastic film wound onto the surface of the film roller, a snap-fit ​​connection mechanism between the two ends of the film roller and the bottom of the frame, a gathering panel mounted at the bottom of the frame, and an adjustment and mounting mechanism between the gathering panel and the frame. The snap-fit ​​connection mechanism includes snap-fit ​​posts and connecting posts. The connecting posts are fixed at both ends of the film roller. The bottom end of the frame has an insertion hole. The connecting posts slide through the insertion hole. The surface of the connecting posts has a snap-fit ​​groove. The snap-fit ​​posts elastically slide through the bottom surface of the frame, and their inner ends slide against the inside of the snap-fit ​​groove. The adjustment and installation mechanism includes a mounting plate and an adjustment plate. The adjustment plate is slidably mounted on the surface of the frame, and the mounting plate is fixed to the bottom end of the adjustment plate, with its bottom end abutting against the bottom end of the receiving panel.

[0007] Furthermore, the film roller is a hollow circular roller structure and is horizontally arranged, the connecting column is a cylindrical structure, the snap-fit ​​groove is an annular groove structure, and the frame is a U-shaped structure.

[0008] Furthermore, guide holes are provided on the upper and lower sides of the insertion hole, and the snap-fit ​​post slides through the guide holes.

[0009] Furthermore, a limiting plate is fixed to the outer end of the snap-fit ​​post, and a tension spring is sleeved on the surface of the snap-fit ​​post. The two ends of the tension spring are respectively connected to the inner side of the limiting plate and the outer side of the frame.

[0010] Furthermore, the receiving panel is inclined and has a gap between it and the plastic film, and the surface of the receiving panel has mounting holes.

[0011] Furthermore, a mounting post is fixed to the bottom end of the mounting plate. The mounting post slides through the mounting hole. The mounting post has a threaded post structure, and a nut is connected to its surface at a position on the surface of the receiving panel. The mounting plate is inclinedly disposed at the bottom end of the adjusting plate.

[0012] Furthermore, the adjusting plate has adjusting holes at both ends, the side of the frame slides through the adjusting holes, the adjusting plate is perpendicular to the side of the frame, and the adjusting plate has a driving hole in the middle, which is a threaded hole structure.

[0013] Furthermore, a reinforcing plate is fixed inside the frame near the top. A rotating hole is opened in the middle of the reinforcing plate. A rotating rod slides through the rotating hole. Limiting rings are fixed on the surface of the rotating rod at positions on both sides of the rotating hole. The rotating rod has a threaded rod structure, and its bottom end rotates through the driving hole. The rotating rod is perpendicular to both the adjusting plate and the reinforcing plate. A rotating frame is fixed at the top of the rotating rod.

[0014] The present invention provides a two-in-one tool for both surface finishing and film covering, which has the following advantages: 1. This utility model fixes connecting columns at both ends of the film roller, pulls the limiting plate and tension spring upward, and opens the bottom end of the frame outward, so that the two ends of the frame are rotatably connected to the connecting columns through the insertion holes. Then, the tension spring is released, and the tension spring pulls the snap-fit ​​column to move into the insertion hole and slides into the snap-fit ​​groove, thereby maintaining a stable installation connection between the frame and the film roller through the connecting columns, and facilitating quick disassembly and installation. It also facilitates the cleaning of concrete debris adhering to the frame and connecting columns, and promotes smooth rotational connection between the frame and the film roller, making it easy to spread plastic film on the concrete surface.

[0015] 2. In this utility model, a detachable finishing panel is installed at the bottom of the frame via an mounting plate and a mounting column. A gap is provided between the finishing panel and the film roller. Thus, by rotating the rotating rod through the rotating frame, the adjusting plate is moved along the side of the frame through the drive hole. In turn, the finishing panel is moved and adjusted at the bottom of the frame via the mounting plate and the mounting column, so that the finishing panel is in different positions at the bottom of the frame. This makes it convenient to lift the frame to different heights and then pull the finishing panel to smooth and finish the concrete surface. Attached Figure Description

This also facilitates the cleaning of concrete debris adhering to the frame 1 and connecting post 12, and promotes smooth rotational connection between frame 1 and film roller 17, making it easy to spread plastic film 11 on the concrete surface.

[0025] Furthermore, the adjustment and installation mechanism includes a mounting plate 7 and an adjustment plate 6. The adjustment plate 6 is slidably mounted on the surface of the frame 1, and the mounting plate 7 is fixed to the bottom end of the adjustment plate 6, with its bottom end abutting against the bottom end of the receiving panel 10.
