Description
Technical Field
[0001] The utility model relates to the technical field of concrete construction, and particularly relates to a device for laying a concrete curing film. Background Art
[0002] With the rapid development of modern construction industry, the requirements for the construction quality and efficiency of concrete are increasing day by day. As one of the most basic and crucial materials in construction engineering, the strength, durability and appearance quality of concrete are directly related to the safety and service life of the whole project. Therefore, the effective curing after concrete pouring is particularly important, and the technological innovation and optimization of film covering, as an economical and widely used curing method, have become the focus of the industry.
[0003] At present, although the method of bending round steel into a triangular structure to assist in laying the film has realized the auxiliary laying of the film to a certain extent, some limitations still exist in the actual application of this technology. When the existing technology needs to cut the film, it often relies on manual use of knives or scissors to cut at specific positions, and it is impossible to cut the film conveniently and quickly, which results in low laying efficiency of the film. In addition, since the laying of the film completely depends on manual dragging of the triangular device, this dragging method only makes the film roll on the concrete surface, and it is difficult to ensure the uniform tension of the film during the laying process, resulting in the film not fitting well with the concrete surface layer during the laying process and affecting the curing effect. Summary of the Utility Model
[0004] The purpose of the utility model is to overcome the problem that when using round steel bent into a triangular structure to assist in laying the film in the prior art, it is impossible to cut the film conveniently and quickly, which results in low laying efficiency of the film, so as to provide a device for laying a concrete curing film.
[0005] The utility model provides a device for laying a concrete curing film, including:
[0006] A handle, and two fork arms are connected to the handle.
[0007] A reel, and both ends of the reel are connected between the two fork arms, and the reel is used for installing a film roll.
[0008] A first roller, and both ends of the first roller are connected to the ends of the two fork arms. The first roller is used for pressing the film onto the concrete surface during the laying process.
[0009] A cutting component, and both ends of the cutting component are connected between the two fork arms, and the cutting component is located between the reel and the first roller.
[0010] A second roller, both ends of the second roller are slidably connected to the two fork arms along the axial direction of the fork arms. The second roller is located between the reel and the first roller. The second roller can approach or move away from the cutting member, and the film can be cut by contacting the second roller with the cutting member.
[0011] The utility model provides a device for laying a concrete curing film. The handle is used to drag the whole device to move when laying the film. The reel is used to install the film roll. The film is led out from the film roll, passes through the area between the cutting member and the second roller, and continues to extend to the lower side of the first roller. Then the film is pressed on the concrete surface by the gravity of the first roller. The second roller can approach or move away from the cutting member. When it is necessary to disconnect the film, the second roller is moved close to the cutting member, and the film is squeezed between the second roller and the cutting member, so that the film can be cut off at the position of the cutting member. Then the second roller is moved away from the cutting member to continue laying the next section of the film. This solution can cut off the film conveniently and quickly, improving the laying efficiency of the film.
[0012] Preferably, the second roller is located between the cutting member and the first roller.
[0013] Preferably, the second roller is provided with a transmission member, and the transmission member can drive the second roller to move. The transmission member improves the convenience of moving the second roller.
[0014] Preferably, both of the fork arms are provided with sliding grooves, and both ends of the second roller are placed in the sliding grooves, and the second roller can approach or move away from the cutting member along the sliding grooves.
[0015] Preferably, the transmission member is a rope, and both ends of the rope are respectively connected to both ends of the second roller. This solution can complete the connection through one rope, and by pulling the middle position of the rope, the two ends of the second roller can be driven to move synchronously, ensuring the synchronism of the movement of both ends of the second roller.
[0016] Preferably, a spring is provided at one end of the sliding groove close to the cutting member, and the spring can reset the second roller.
[0017] Preferably, both ends of the reel are detachably connected to the two fork arms. This solution is convenient for replacing the film roll.
[0018] Preferably, both of the fork arms are provided with installation grooves, the installation grooves are provided with openings, and both ends of the reel can be put into the installation grooves or taken out from the installation grooves through the openings. The detachable connection method of this solution makes the replacement of the film roll more convenient.
[0019] Preferably, the cutting member is provided with a flash structure detachably connected thereto. By using the flash structure and the second roller to extrude the film, the convenience of cutting the film can be improved. The flash structure is a strip-shaped member arranged along the axial direction of the cutting member, and the strip-shaped member has irregular burrs. The burrs can pierce the film under the extrusion action to achieve the effect of disconnecting the film. Compared with a blade, the flash structure is safer during the construction process because it avoids the risk of cuts that may be caused by direct contact with the blade.
[0020] Preferably, the flash structure and the cutting member are connected by spot welding. After the flash structure is worn, it can be conveniently removed and a new flash structure can be spot welded again. This solution ensures the firm connection of the flash structure; at the same time, it reduces the difficulty of replacement.

[0044] Embodiment 1
[0045] As Figures 1 to 3 shown, a device for laying a concrete curing film includes a handle 1, a fork arm 2, a reel 3, a cutting member 5, a first roller 7, and a second roller 6.
[0046] Two fork arms 2 are connected to the handle 1.
[0047] Both ends of the reel 3 are connected between the two fork arms 2, and the reel 3 is used for installing the film roll 4.
[0048] Both ends of the first roller 7 are connected to the ends of the two fork arms 2. The first roller 7 is used for rolling forward during the laying process and pressing the film 8 onto the concrete surface. The film 8 is not shown Figure 2 in the figure.
[0049] Both ends of the cutting member 5 are connected between the two fork arms 2, and the cutting member 5 is located between the reel 3 and the first roller 7. The cutting member 5 can be provided with a blade, a serrated edge, or a burr structure for cutting the film 8.
[0050] Both ends of the second roller 6 are slidably connected to the two fork arms 2 along the axial direction of the fork arms 2. The second roller 6 is located between the reel 3 and the first roller 7. The second roller 6 can approach or move away from the cutting member 5, and the film 8 can be cut by the contact between the second roller 6 and the cutting member 5.
[0051] The two ends of the second roller 6 can be slidably connected to the two fork arms 2 in such a way that U-shaped blocks are provided at both ends of the second roller 6, the size of the U-shaped blocks matches that of the fork arms 2, the fork arms 2 are placed in the U-shaped blocks, and the U-shaped blocks can slide along the length direction of the fork arms 2 within a certain range to achieve the purpose of sliding connection. The way of the sliding connection can also be that sliding grooves 22 are formed on the fork arms 2, and sliding blocks matching the sliding grooves 22 are provided at both ends of the second roller 6, and the sliding blocks can slide within the sliding grooves 22 to realize the sliding connection.
[0052] The positional relationship between the cutting member 5 and the second roller 6 can be that the second roller 6 is located between the cutting member 5 and the first roller 7. During the use of this device, the second roller 6 can naturally droop under the action of gravity, so as to be away from the cutting member 5. When it is necessary to cut the film 8, a force pointing to the cutting member 5 is applied to the second roller 6 to make it close to the cutting member 5.
[0053] The positional relationship between the cutting member 5 and the second roller 6 can also be that the cutting member 5 is located between the second roller 6 and the first roller 7. During the use of this device, by applying a force away from the cutting member 5, the second roller 6 is made to be away from the cutting member 5. When it is necessary to cut the film 8, the force applied to the second roller 6 is stopped, and at this time the second roller 6 can approach the cutting member 5 under the action of gravity.
[0054] In an alternative embodiment, the second roller 6 can be located between the cutting member 5 and the first roller 7. As Figure 2 shown, the reel 3, the cutting member 5, the second roller 6 and the first roller 7 are all parallel to each other, and in the arrangement order from top to bottom, they are the reel 3, the cutting member 5, the second roller 6, and the first roller 7 in sequence. In this embodiment, as Figure 1 shown, the film 8 is led out from the upper side of the film roll 4, passes through the area between the cutting member 5 and the second roller 6, and continues to wind around the lower sides of the second roller 6 and the first roller 7, and then is laid on the surface of the concrete. In this embodiment, the second roller 6 also serves the function of tensioning the film 8.

The transmission member 9 can be a connecting rod, one end of the connecting rod is rotatably connected to the second roller 6, and pulling or pushing the other end of the connecting rod along the axial direction of the connecting rod can drive the second roller 6 to move. The transmission member 9 can also be a rope, a part of the rope is connected to the second roller 6, and pulling the rope can drive the second roller 6 to move. It should be noted that the transmission member 9 is not shown in Figure 1 the figure.
[0056] In an alternative embodiment, the transmission member 9 may be a rope, and both ends of the rope are respectively connected to both ends of the second roller 6. The middle part of the rope is close to the handle 1 for facilitating the pulling of the rope.

When the spring 61 is compressed, it can provide a force to move the second roller 6 back to the initial position. When a force is applied to the second roller 6 to move it closer to the cutting member 5, the spring 61 will be compressed. When the force applied to the second roller 6 stops, the compressed spring 61 and the gravity of the second roller 6 together move the second roller 6 in a direction away from the cutting member 5, that is, restore the second roller 6 to the initial position.
