Description

Technical Field

[0001] The present application relates to the technical field of concrete curing, and in particular to a tool for rapid laying of concrete curing membranes. Background Art

[0002] Concrete construction is an indispensable process in current infrastructure construction, and concrete maintenance is a key point that affects the quality control of the main concrete project. Film maintenance is a maintenance method that covers concrete structures or components. After the initial setting of concrete and before the final setting, the concrete maintenance film is manually laid to make the concrete maintenance film and the concrete surface closely combined, promote the hydration effect of concrete, and play a significant role in preventing cracks and moisturizing during the concrete maintenance process.

[0003] For large concrete floors, due to the large net depth of the main building, it is impossible to ensure that the film can be covered smoothly. In addition, the newly laid concrete floor has not yet solidified, and the marks left by people walking on the finished concrete will affect the appearance of the concrete surface. The workers in the middle cannot get close, making it difficult to lay the maintenance film in this area. If the concrete surface cannot be fully covered, the concrete surface will crack due to inadequate maintenance, affecting the quality of the concrete.

[0004] In the patent document with the announcement number CN 216076419 U, a concrete curing film covering tool is disclosed, including a push rod, a surface collecting drag plate for smoothing the concrete surface is provided at the lower end of the push rod, a film covering roller for winding the ground film is provided behind the surface collecting drag plate, a rolling tube is passed through the film covering roller, a traction frame for connecting the rolling tube and the push rod is provided between the rolling tube and the push rod, and a fixed frame is provided on the push rod along its length direction, and the upper end of the traction frame is passed through and hung in the fixed frame and can move and rotate back and forth in the fixed frame. When in use, the worker pulls the push rod and uses the rolling of the film covering roller to cover the curing film on the concrete surface. Although this method saves some effort for the workers in film covering and makes film covering faster, there is still a problem: for larger concrete paving areas, the central range is still inaccessible.

[0005] To this end, the present application provides a tool for rapid laying of concrete curing membrane to increase the coverage of the membrane. Utility Model Content

[0028] The following will be combined with the attached examples of the present application Figure 1-6 , the technical solutions in the embodiments of the present application are described clearly and completely. Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments.

[0029] In order to solve the problems existing in the prior art, the present embodiment provides a tool for quickly laying concrete curing membrane, including an arc-shaped traction frame 1, a pull rope is tied to the bent portion of the traction frame 1, and insertion rods 2 are provided at both ends of the traction frame 1. The suspended ends of the two insertion rods 2 are arranged opposite to each other, and an elastic member 3 is pulled between the two ends of the traction frame 1.

[0030] Principle details of this embodiment:

[0031] A tool for rapid laying of concrete curing membranes, comprising an arc-shaped traction frame 1, which can be C-shaped or V-shaped, and is made of a tough material, such as round steel metal (diameter not exceeding 10 mm) such as stainless steel bars, aluminum bars, or tough plastic. A pull rope is tied to the bent portion of the traction frame 1, and the two ends of the traction frame 1 are horizontally bent to form two insertion rods 2, the suspension ends of the two insertion rods 2 are arranged oppositely and the axes coincide, and the two ends of the traction frame 1 near the insertion rods 2 are jointly pulled with elastic members 3.

[0032] When in use, open the two ends of the traction frame 1 so that the insertion rods 2 on both sides are respectively inserted into the two ends of the curing film reel 12. Place the curing film reel 12 on the concrete surface, and pull the traction frame 1 by pulling the rope to pull the curing film reel 12 to roll on the concrete surface, so as to lay the curing film. For larger concrete floors, by adjusting the length of the binding rope, or connecting the rope, the curing film drum can be placed on one side of the concrete floor, and the worker stands on the other side to pull. In this way, the operating range of curing film laying can be greatly expanded, and the convenience of curing film laying on large concrete floors is greatly improved. In this way, not only is it avoided that the workers step on it and cause unnecessary secondary surface collection, which leads to increased construction costs, but it also reduces the workers' own position adjustment, and the coverage is in place with one pull. The curing film reel 12 can be inserted and removed by stretching the traction frame 1, which is easy to operate. And during the pulling process, the two ends of the traction frame 1 tend to be buckled through the elastic member 3, so that the insertion rod 2 is firmly inserted into the two ends of the curing film reel 12, thereby preventing the curing film reel 12 from falling off during the pulling process.

[0033] In this embodiment, the traction frame 1 can be made by processing through equipment or by workers randomly selecting materials from waste gas materials, which is very convenient. It has a simple structure, is easy to make, is compact and flexible, and can be made locally and processed at any time. When using the equipment in this solution, operators can effectively control the paving area of ​​the film, and the appearance quality of the concrete can also be improved, greatly improving the acceptance rate of concrete projects.

[0034] In the present application, the traction frame 1 has various sizes and can adapt to the application of curing film covering with different widths.

[0035] In a further embodiment of the present invention, two sleeves 6 and a pressure roller 8 are further included. The side walls of the sleeves 6 are fixed with mounting rods 7. Insertion holes are provided at both ends of the pressure roller 8. During installation, the two sleeves 6 are pressed against the two ends of the curing film reel 12 with their opposite sides, and against the bent connection between the traction frame 1 and the insertion rod 2 with their opposite sides, thereby limiting the sleeves 6 and preventing them from deflecting or shaking during the pulling process.

[0036] This embodiment has two usage states:

[0037] The first type: the pressure roller 8 is located in front of the curing film reel 12 in the direction of travel: the pressure roller 8 is plugged into the two plug rods 2, and the curing film reel 12 is plugged into the two mounting rods 7. During the pulling process, the pressure roller 8 will flatten the concrete floor within the curing film laying range to prevent the curing film from being scratched by punctures.

[0038] The second type: the pressure roller 8 is located at the rear side of the curing film reel 12 in the direction of travel: the pressure roller 8 is plugged into the two mounting rods 7, and the curing film reel 12 is plugged into the two plugging rods 2. During the pulling process, the pressure roller 8 will roll over the surface of the laid curing film, so that the curing film and the concrete are closely attached to prevent the loose attachment from being blown away by the wind and affecting the laying effect.

[0039] Preferably, two sets of shaft sleeves 6 and mounting rods 7, that is, two sets of pressure rollers 8, one each before and after the curing film reel 12, can be provided to achieve the above two effects.

[0040] In a further embodiment of the present invention, the inner sides of both ends of the traction frame 1 are provided with hanging ears 4, and the two hanging ears 4 are buckled with collars 5, and the elastic member 3 is arranged between the two collars 5. The elastic member 3 is detachable and easy to replace. In addition, before the traction frame 1 is stretched, the collar 5 on one side of the elastic member 3 is removed from the hanging ears 4, which can also reduce the stretching resistance.

[0041] In a further embodiment of this solution, the elastic member 3 is any one of an elastic rope and a spring, which can meet the tightening requirements and are also convenient to obtain.

[0042] In a further embodiment of the present invention, a fixing sleeve 9 is provided at the center of the bent portion of the traction frame 1, and a hook 11 is screwed on the side wall of the fixing sleeve 9, and the pull rope is tied to the hook 11. The hook 11 prevents the tied end of the pull rope from being offset during the pulling process, and also allows the pulling force to be located on the center line of the traction frame 1 to avoid pulling deviation. Moreover, the hook 11 is spirally installed on the traction frame 1, and can be removed and replaced after being deformed due to long-term pulling use.

[0043] In a further embodiment of the present invention, the fixing sleeve 9 is a C-shaped open sleeve. The fixing sleeve 9 has a certain toughness and can be opened and stretched to be removed, which is convenient and quick.

[0044] In a further embodiment of the present invention, the two side walls of the opening of the fixing sleeve 9 are provided with extension platforms, and the two extension platforms are provided with through holes, and bolts are inserted into the two through holes, and nuts are installed on the bolts to abut against the bottom wall of the lower extension platform. The fixing sleeve 9 is more firmly installed by the bolt and nut connection to avoid the phenomenon of active deviation.

[0045] In a further embodiment of the present solution, a U-shaped inserting bracket 10 is provided on the side wall of the fixing sleeve 9, a threaded hole is provided in the center of the inserting bracket 10, and a thread is provided at the bottom end of the hook 11, so that the hook 11 can be detachably installed on the inserting bracket 10. The inserting bracket 10 is arranged opposite to the opening of the fixing sleeve 9, and does not affect the expansion of the opening of the fixing sleeve 9. The arrangement of the inserting bracket 10 also increases the installation size of the hook 11, and the installation stability of the hook 11 can be improved by screwing a nut at the bottom end of the hook 11 on the lower side of the inserting bracket 10.
