Description

Technical Field

[0001] This application relates to the field of concrete curing technology, and in particular to a curing film application tool that can be operated by a single person. Background Technology

[0002] The application of concrete curing membrane is an important method in the concrete curing process. It aims to keep the concrete moist by covering it with a curing membrane, prevent moisture evaporation, and thus promote cement hydration, thereby improving the strength and durability of the concrete.

[0003] In existing technologies, the application of curing film is usually done manually by unwinding the roll, which generally requires multiple people to work together.

[0004] Regarding the aforementioned technologies, the inventors believe that this method results in slow laying speed, reduced efficiency, and impact on the construction period. Utility Model Content

[0005] The purpose of this application is to provide a single-person operation tool for laying maintenance films, in order to improve the problem of slow laying speed, inefficiency, and impact on construction period caused by the multi-person cooperation and collaborative operation of laying maintenance films.

[0006] This application provides a protective film application tool for single-person operation, which adopts the following technical solution:

[0007] A single-person operated curing film laying tool includes a slide plate placed on concrete; the slide plate has a through groove, and a film roll frame is arranged above the through groove, which slides relative to the slide plate in a vertical direction. A film roll roller for holding curing film rolls is rotatably arranged inside the film roll frame. The film roll frame can slide into the through groove so that the curing film on the film roll roller abuts against the concrete; the slide plate is provided with a drag bar along its traveling direction.

[0008] By adopting the above technical solution, the film roll is placed on the cement ground for easy dragging. By installing the film roll frame on the film roll, the curing film is pressed against the concrete surface through the through groove. This allows the film roll roller to rotate and evenly lay the curing film along the direction of travel when the operator drags the film roll with a drag bar. This makes it easy for one person to operate, quick and convenient, and improves work efficiency.

[0009] Optionally, height adjustment components are provided on both sides of the through groove. The height adjustment components are connected to the film roll frame. The height adjustment components include a fixed plate and a movable frame. The fixed plate has a sliding groove on the side near the through groove. The two ends of the movable frame slide synchronously in the sliding groove. The fixed plate is provided with fixing bolts that can abut against the movable frame to fix the movable frame.

[0010] By adopting the above technical solution, the height of the film roll frame can be easily adjusted by setting the height adjustment component, and the tightness of the curing film on the film roll against the concrete can be controlled. This is conducive to laying the curing film tightly according to actual needs, improving the laying quality of the curing film, and increasing the practicality of the device. The moving frame can be stabilized by setting fixing bolts to maintain its height and stability.

[0011] Optionally, a plurality of springs are provided between the movable frame and the film roll frame, with the two ends of the springs connected to the movable frame and the film roll frame respectively.

[0012] By adopting the above technical solution, and by setting up a spring-connected moving frame and film roll frame, the film roll frame has a certain buffering capacity and tight fitting ability, thereby improving the quality of curing film laying; at the same time, it enhances the adaptability of the bottom surface of the film roll frame and protects the film roll frame from damage when the concrete surface obstructs the movement of the film roll frame.

[0013] Optionally, the film roll holder is threaded at both ends with quick-release bolts that allow the film roll to rotate.

[0014] By adopting the above technical solution, the quick-release bolts are used to rotate and connect the film-rolling roller, which facilitates the rotation of the film-rolling roller to unroll the curing film. The quick-release bolts also facilitate the disassembly of the film-rolling roller, so as to add the curing film to the film-rolling roller and complete the large-area concrete paving.

[0015] Optionally, a plurality of pressure rollers are rotatably arranged in the through groove, parallel to the film rolling roller, and the pressure rollers are arranged on the side of the fixed plate away from the drag bar.

[0016] By adopting the above technical solution, and by setting a pressure roller to flatten the curing film immediately after laying it, the curing film is laid flat and tightly, thus improving the quality of the curing film laying.

[0017] Optionally, a vibrating plate is provided on the side of the fixed plate near the tow rod in the through groove. A vibrating motor for vibrating the vibrating plate is provided on the vibrating plate. Several connecting rods are connected between the vibrating plate and the tow plate. The two ends of each connecting rod are rotatably connected to the tow plate and the vibrating plate, respectively, so as to maintain the synchronous movement of the vibrating plate and the tow plate in the direction of travel without hindering the vibration of the vibrating plate.

[0018] By adopting the above technical solution, and by setting a vibratory motor to drive the vibratory plate to vibrate, the concrete surface can be kept more moist. Vibration compaction reduces the voids on the concrete surface, allowing the curing film to adhere more tightly to the concrete surface, preventing rapid evaporation of moisture, and thus improving the curing effect. The sliding plate is hinged to connect the vibratory plate and drive it to move synchronously without affecting the vibration compaction of the vibratory concrete.

[0019] Optionally, the tow bar is hinged to the tow plate.

[0020] By adopting the above technical solution, the tow bar set by the hinged tow plate makes it easy for operators of different heights and operating habits to operate the tow bar to pull the tow plate to lay the curing film.

[0021] Optionally, the side of the slide away from the pressure roller is provided with an arc-shaped traveling surface.

[0022] By adopting the above technical solution and setting a travel surface, the travel resistance in the direction of the slide is reduced, saving effort and making it easier for the operator to drag.

[0023] In summary, this application includes at least one of the following beneficial technical effects of a single-person operation protective film application tool:

[0024] 1. By setting up a sliding plate to be placed on the cement ground for easy dragging, and by installing the film roll frame on the sliding plate, the curing film is made to abut against the concrete surface through the through groove. This allows the film roll roller to rotate and evenly lay the curing film along the direction of travel when the operator drags the sliding plate with a tow bar. This makes it easy for one person to operate, quick and convenient, and improves work efficiency.

[0025] 2. The height adjustment component facilitates the adjustment of the film roll frame height, controls the tightness of the curing film on the film roll against the concrete, which is beneficial for laying the curing film tightly according to actual needs, improving the laying quality of the curing film, and increasing the practicality of the device; the moving frame is stabilized by fixing bolts to maintain its height and stability.

[0026] 3. By setting a vibratory motor to drive the vibratory plate, the concrete surface can be kept more moist. Vibration compaction reduces the voids on the concrete surface, allowing the curing film to adhere more tightly to the concrete surface, preventing rapid evaporation of moisture, and thus improving the curing effect. The sliding plate is hinged to drive the vibratory plate to move synchronously without affecting the vibration compaction of the vibratory concrete. Attached Figure Description
