Description

Technical Field

[0001] This invention relates to the field of building construction technology, and in particular to a concrete curing and covering device for building construction. Background Technology

[0002] In construction sites, concrete foundations, large areas, main structural concrete slabs, and stairs are typically vibrated and compacted after pouring, followed by curing with a protective film. After the initial setting and before the final setting of the concrete, a concrete curing film is manually applied to ensure a tight bond between the film and the concrete surface, promoting hydration and providing crack prevention and moisture retention during the curing process. During the curing process, any depressions or protrusions in the concrete require manual repair to ensure proper coverage and prevent unevenness of the substrate. Traditional curing methods typically use a simple roller and are applied by hand. For example, patent document CN107956291B discloses a concrete curing tool that uses up-and-down vibration to prevent the film from not adhering properly to the substrate. However, for depressions or protrusions in the concrete, manual repair is still necessary, resulting in a significant workload. Furthermore, when the concrete's setting strength is low, manual entry into the site can easily damage the site. Summary of the Invention

[0003] In view of the above situation and to solve the problems existing in the prior art, the purpose of this invention is to provide a concrete film curing device for building construction, which can effectively solve the problems of cumbersome repair operations and low film curing efficiency.

[0004] The technical solution includes a transverse main beam, with a hopper installed at both ends of the main beam. Each hopper has a front-to-back support roller installed at its lower end via a bracket. Multiple material distribution devices are arranged sequentially at the lower end of the hopper.

[0005] The fabric feeding device includes an elastic telescopic rod on the outside and a vertical tube on the inside. The lower end of the telescopic rod is equipped with a roller. The upper end of the vertical tube is sealed and the side wall is provided with an opening. The upper end of the vertical tube is placed in the hopper. The vertical tube can move up and down and return to its original position. After the telescopic rod moves down, it can drive the vertical tube to rise, so that the opening on the side wall of the vertical tube is placed in the hopper.

[0006] A detachable film roll is installed in the middle of the main beam; a vertical rod fixed to the main beam is provided on both the left and right sides of the film roll, and a mounting plate is hinged to the lower end of each vertical rod; a pressure roller is installed on one end of each mounting plate facing the center of the film roll, and a scraper that can move back and forth vertically to the mounting plate and return to its original position is installed on the other end; two control rods that can move up and down are provided on the main beam, and the lower ends of the two control rods can squeeze the left and right mounting plates respectively, causing the mounting plates to tilt.

[0007] In order for the pressure roller to automatically press the film, a first tension spring is connected between the vertical rod and the mounting plate. The first tension spring causes the end of the mounting plate with the pressure roller to tilt downwards.

[0008] In order to enable the scraper to move back and forth vertically to the mounting plate and return to its original position, the scraper passes through the mounting plate, and a second tension spring is connected between the upper end of the scraper and the mounting plate.

[0009] Advantages of this invention: 1. This device eliminates the need for personnel to enter the construction site, avoiding damage and enabling remote construction. 2.

[0015] The specific embodiments of the present invention will be further described in detail below with reference to the accompanying drawings.

[0016] Depend on Figures 1 to 5 The present invention includes a transverse main beam 1, with a hopper 2 installed at both the left and right ends of the main beam 1, and a front-to-back support roller 5 installed at the lower end of each hopper 2 via a bracket 3; and multiple material feeding devices arranged in a front-to-back sequence are provided at the lower end of the hopper 2.

[0017] The fabric feeding device includes an elastic telescopic rod 4 on the outer side and a vertical tube 6 on the inner side. A roller 7 is installed at the lower end of the telescopic rod 4. The upper end of the vertical tube 6 is sealed and the side wall is provided with an opening 8. The upper end of the vertical tube 6 is placed in the hopper 2. The vertical tube 6 can move up and down and return to its original position downward. After the telescopic rod 4 moves downward, it can drive the vertical tube 6 to rise, so that the opening 8 on the side wall of the vertical tube 6 is placed in the hopper 2.

[0018] A detachable film roll 9 is installed in the middle of the main beam 1; a vertical rod 10 fixed on the main beam 1 is provided on both the left and right sides of the film roll 9, and a mounting plate 11 is hinged to the lower end of each vertical rod 10; a pressure roller 12 is installed on one end of each mounting plate 11 facing the center of the film roll 9, and a scraper 13 that can move back and forth vertically to the mounting plate 11 and return to its original position is installed on the other end; two control rods 14 that can move up and down are provided on the main beam 1, and the lower ends of the two control rods 14 can squeeze the two mounting plates 11 on the left and right respectively, so that the mounting plates 11 are tilted.

[0019] In order for the pressure roller 12 to automatically press the film, a first tension spring 15 is connected between the vertical rod 10 and the mounting plate 11. The first tension spring 15 causes the end of the mounting plate 11 with the pressure roller 12 to tilt downward.

[0020] In order to enable the scraper 13 to reciprocate and return to its original position vertically to the mounting plate 11, the scraper 13 passes through the mounting plate 11, and a second tension spring 16 is connected between the upper end of the scraper 13 and the mounting plate 11.

[0021] To achieve the upward movement of the vertical tube 6 when the telescopic rod 4 descends, the telescopic rod 4 consists of an outer shell and an inner core, with a spring between the outer shell and the inner core. A roller 7 is installed at the lower end of the inner core. A lever 17 is provided on the side wall of the inner core and the side wall of the vertical tube 6. A support shaft 18 in the front-to-back direction is provided on the bracket 3. A swing rod 19 that can swing is installed on the support shaft 18. The left and right ends of the swing rod 19 are located below the left and right levers 17.

[0022] In order to achieve the downward reset of the vertical tube 6, a compression spring 20 is fitted on the vertical tube 6.

[0023] To prevent concrete from adhering to the support rollers 5 and 7, mudguards 21 are provided on both the bracket 3 and the telescopic rod 4.

[0024] To facilitate the installation and replacement of the film roll 9, a through groove 22 is provided in the middle of the main beam 1, and the entire film roll 9 is placed in the through groove 22. A groove 23 is provided in the middle of the main beam 1, and the front and rear ends of the mandrel inside the film roll 9 are placed in the groove 23.

[0025] To facilitate construction, a hook 24 and a handrail 25 are installed on the outer side walls of both hoppers 2.

[0026] In order to control the stroke of the control rod 14, the control rod 14 passes through the main beam 1 and is provided with multiple positioning holes. The main beam 1 is provided with corresponding through holes, and the control rod 14 is controlled by a pin.

[0027] In use, the device is symmetrically arranged on both sides, allowing it to move bidirectionally. In actual use, concrete is first filled into the hoppers 2 on both sides. Support rollers 5 are mounted below each hopper 2 via brackets 3, thus supporting the entire device. The device is then placed horizontally on the surface of the concrete to be coated.

[0028] This device has two driving methods. The first method involves connecting ropes on both sides, with two workers standing on each side of the construction site. The two workers alternately pull the ropes, allowing the device to move left and right within the site without requiring personnel to enter. The second method involves personnel entering the site holding a handle 25mm to push and pull the device. The second method is suitable when the concrete has already set sufficiently for standing, while the first method is suitable for newly poured concrete. The appropriate method should be chosen based on the site conditions.

[0029] Taking the movement of this device from left to right as an example, the working principle is explained as follows: First, when the device moves from left to right, the control lever 14 on the right side needs to be pressed down and the control lever 14 on the left side needs to be pulled up. The position of the control lever 14 is then fixed using tools such as pins or bolts. At this time, the right ends of the mounting plates 11 on both the left and right sides are tilted downwards, that is, the scraper 13 on the right mounting plate 11 is facing downwards and the pressure roller 12 is raised, while the pressure roller 12 on the left mounting plate 11 is facing downwards and the scraper 13 is raised.

[0030] At this point, pull out the end of the film and spread it to the left after passing it around the pressure roller 12 on the left; this completes the initial setup of the device; then, pull the entire device to the right to achieve automated spreading.

[0031] Since the roller 7 located below the hopper 2 on the right side is at the foremost position, when the concrete base layer is depressed, the roller 7 corresponding to the depression will move downward under the action of the spring inside the telescopic rod 4, causing the inner core of the telescopic rod 4 to move downward as well. Then, the lever 17 on the telescopic rod 4 will actuate the swing rod 19, causing the left end of the swing rod 19 to tilt upward and push the corresponding precast vertical pipe 6 upward. After the vertical pipe 6 moves upward, the opening 8 on the side wall of the vertical pipe 6 will be inside the hopper 2. Subsequently, the concrete inside the hopper 2 will flow downward through the opening 8 on the side wall of the vertical pipe 6 and fall onto the concrete base layer.

[0032] The falling concrete is then spread out by the scraper 13, repairing depressions in the base layer. Furthermore, the scraper 13 also levels and spreads out higher areas of the base layer, achieving the effect of leveling high areas and repairing low areas; eliminating the need for manual repairs and greatly improving repair efficiency.

[0033] After the base layer is leveled by the scraper 13, the pressure roller 12 on the rear side of the device will press the film tightly on the base layer under the action of the first tension spring 15, thus achieving the spreading of the film.

[0034] Once the device is moved to the right end of the site, lift it forward or backward and continue the above operation. The difference this time is that the device needs to be pulled to the left to achieve automatic repair and coating again.

[0035] The entire device is supported by the left and right support rollers 5, while the telescopic rod 4 and the lower roller 7 do not provide support. Therefore, the height of the entire device off the ground remains constant. As a result, the positions of the lever 17 and the swing rod 19 in the fabric device can maintain a stable correspondence and are not affected by the weight of the entire device.

[0036] In this device, the two mounting plates 11 on the left and right are symmetrical and complement each other. When the scraper 13 of the right mounting plate 11 is working, the pressure roller 12 on the left is working, and vice versa. At the same time, when one end of the mounting plate 11 is working, the other end is raised to avoid interference between the two mounting plates 11 and to ensure that concrete does not stick when the pressure roller 12 is not working.

[0037] This device allows two workers to move left and right by pulling on ropes, eliminating the need for workers to enter the site and preventing them from affecting the concrete and causing unevenness such as footprints, which could affect the coating. It can also be used with partially set concrete and sites where the concrete strength is not high, thus expanding its applicability and simplifying the operation.
