Description

Technical Field

[0001] The present invention relates to the field of building construction, and particularly to a concrete film covering device. Background Art

[0002] After concrete is poured, if the climate is hot and the air is dry, and curing is not carried out in time, the water in the concrete will evaporate too quickly, forming a dehydration phenomenon, which will cause the cement particles that have formed a gel to not be fully hydrated and cannot be transformed into stable crystals, lacking sufficient bonding force, and thus flaky or powdery peeling will occur on the concrete surface. In addition, when the concrete does not yet have sufficient strength, premature evaporation of water will also cause large shrinkage deformation and dry shrinkage cracks. Therefore, the curing in the initial stage after concrete pouring is very important, and curing should be carried out immediately after the concrete has finally set. Covering with a film for curing can continuously keep the moisture and maintain the surface temperature, prevent early cracking, reduce vertical capillary channels, maintain the tensile capacity of the concrete, and effectively resist the generation of cracks in the middle and late stages.

[0003] The traditional laying of concrete film materials is in the way of manual hand-pulling, vibrating and leveling the surface on the wet concrete and then laying the film. The existing concrete film covering machines simply combine the vibrating plate and the reel, and lay the film by the way of manual hand-pulling. The above laying methods rely on a large amount of labor, have low efficiency, and at the same time have problems such as waste of film materials and non-standard operations, and it is difficult to ensure the compliance and high efficiency of the laying work.

When the membrane material is laid, the position of the cutting piece is moved to cut the membrane material, and the frame is moved upward to make the roller leave the concrete surface, which solves the problem of low efficiency and waste of manpower and material resources in the traditional concrete film coating method.

[0034] like Figures 1 to 3 As shown, the concrete film covering device of the present invention comprises:

[0035] A frame 11 mounted on the power equipment in a height-adjustable manner;

[0036] A vibrating ruler 111 mounted on the frame 11 and capable of reciprocating up and down to vibrate the surface of the concrete;

[0037] The reel 112 mounted on the frame 11 is rotated, and the reel 112 rolls up the film material 1121;

[0038] Rotate the roller 12 mounted on the frame 11 and parallel to the reel 112, and the roller 12 is located on the side of the reel 112 away from the vibrating ruler 111, so that the membrane 1121 passes around the bottom of the roller 12 and adheres to the surface of the concrete; and

[0039] The cutting member 14 is adjustably mounted on the frame 11 and is disposed corresponding to the roller 12 . The cutting member 14 is moved so as to cut the film material 1121 .

[0040] Furthermore, it also includes a cylinder 15 with one end fixed to the power equipment and telescopically adjustable, and the other end of the cylinder 15 is fixedly connected to the frame 11.

[0041] Specifically, it also includes a vibration motor installed on the vibrating ruler 111.

[0042] As a preferred embodiment of the present invention, it also includes a toggle member 121 with a U-shaped vertical section and an end portion rotatably connected to the frame 11, the film 1121 is sandwiched between the toggle member 121 and the roller 12, and the cutting member is located on the side of the roller 12 away from the reel 112;

[0043] The outer wall of the drum 12 is used to rotate the toggle member 121 to the top of the cutting member 14 , so as to drive the film material 1121 below the drum 12 to be lifted to the cutting member 14 , and then the cutting member 14 is moved to cut the film material 1121 .

[0044] Specifically, the drum 12 is rotatably connected to the frame 11 via a rotating shaft;

[0045] The toggle member 121 includes two end plates that are oppositely arranged and respectively located on both sides of the roller 12 and an arc plate connected to the opposite ends of the two end plates. The arc plate is arc-shaped to match the surface of the roller 12. The end of the end plate away from the arc plate is sleeved on the rotating shaft, and the film material 1121 is clamped between the arc plate and the roller 12.

[0046] Preferably, two shifting members 121 are symmetrically arranged along the rotation axis.

[0047] Furthermore, it also includes a telescopic member 13 installed on the frame 11 and located above the cutting member 14. The length of the telescopic member 13 is adjustable. By extending the telescopic member 13, the telescopic member 13 can be pressed against the film material 1121 lifted to the top of the cutting member 14 by the shifting member 121.

[0048] Specifically, it also includes a groove 1211 corresponding to the telescopic member 13 and opened on the arc plate. By extending the telescopic member 13, the telescopic member 13 is pressed against the corresponding film material 1121 and passes through the groove 1211 and presses against the film material 1121 attached to the roller 12 and the roller 12.

[0049] Furthermore, the cutting member 14 includes two guide rails arranged opposite to each other and mounted on the frame 11, a slider slidably mounted on the guide rails, and a heating wire connected to the two sliders;

[0050] The slider moves along the guide rail toward the film material 1121 , and then the film material 1121 is cut by the electric heating wire.

[0051] The specific implementation of the present invention is as follows:

[0052] The frame 11 is lowered by the cylinder 15 so that the roller 12 is placed on the surface of the concrete. At this time, the membrane material 1121 bypasses the bottom of the roller 12 and is placed on the surface of the concrete. The vibrating ruler 111 is turned on and moved along the concrete surface. Figure 3 ① In the figure, the power device (which may be a mobile trolley, etc.) is moved in the direction of the arrow, so that the vibrating ruler 111 vibrates the surface of the concrete, and the reel 112 rotates to release the membrane material 1121 and the roller 12 presses over the membrane material 1121, so that the membrane material 1121 is attached to the surface of the concrete. At this time, the toggle member 121 is located at a position close to the bottom of the roller 12 (i.e., the position marked 1 in the figure), and the membrane material 1121 is between the toggle member 121 and the roller 12;

[0053] After the film material 1121 is laid, the cylinder 15 is used to lift the frame 11 upward (as shown in Figure ②), and the toggle member 121 is rotated (as shown in Figure ③). At this time, the toggle member 121 rotates clockwise in the figure (rotated to the position marked 2 in the figure), so that part of the film material 1121 is lifted above the cutting member 14, and there are two layers of film material 1121 at the cutting member 14 (one layer is the lifted film material close to the cutting member, and the other layer is the film material attached to the surface of the roller, and there is a set distance between the lifted film material and the film material attached to the roller to prevent the cutting member from cutting the lifted film material and cutting the film material attached to the roller);

[0054] The telescopic member 13 is extended (as shown in FIG. ④ ), so that the telescopic member 13 abuts against the lifted film material 1121 and abuts against the film material 1121 attached to the roller 12 through the groove 1211 of the arc plate and against the roller 12, thereby fixing the film material 1121, and then the cutting member 14 is moved in the direction of the arrow, so that the electric heating wire of the cutting member 14 cuts the lifted film material 1121;

[0055] At this time, the power equipment can be used to move the frame 11 to the position where the next membrane material 1121 is to be laid, and the cutting member 14 is moved (as shown in FIG. ⑤) and the toggle member 121 is rotated counterclockwise (so that the toggle member returns to the position marked 1). Since the telescopic member 13 is still against the membrane material 1121 at this time, the membrane material 1121 has not been put down yet;

[0056] The frame 11 is moved downward by the cylinder 15 (as shown in FIG. 6 ), the roller is placed on the surface of the concrete, and part of the membrane material 1121 is pressed under the roller 12;

[0057] The telescopic member 13 is retracted (as shown in FIG. 7 ), and the lifted membrane material 1121 falls to the surface of the concrete due to gravity, and the above steps can be repeated for coating.

[0058] The present invention also provides a method for using the concrete film covering device, the method comprising the following steps:

[0059] A concrete coating device is provided to adjust the height of the frame 11 so that the roller 12 fits the surface of the concrete;

[0060] The frame 11 is driven by a power device to move along the surface of the concrete, and the vibrating ruler 111 is reciprocated up and down, so that the vibrating ruler 111 vibrates the surface of the concrete and the membrane material 1121 is laid on the vibrated surface of the concrete;

[0061] After the film material 1121 is laid, the cutting member 14 is moved to cut the film material 1121 .

[0062] The specific operation mode of the actual implementation of the method provided by the present invention is as follows:

[0063] Lower the frame body 11 by using the air cylinder 15 so that the roller 12 is placed on the surface of the concrete. At this time, the film material 1121 bypasses the bottom of the roller 12 and is placed on the surface of the concrete. Turn on the vibrating ruler 111 and move the power equipment (which can be a moving trolley, etc.) along the Figure 3 direction of the arrow in Figure ①. Thus, the vibrating ruler 111 levels the surface of the concrete, and the reel 112 rotates to release the film material 1121 and the roller 12 presses on the film material 1121, making the film material 1121 adhere to the surface of the concrete. At this time, the toggling member 121 is located at a position close to the bottom of the roller 12 (i.e., the position labeled 1 in the figure), and the film material 1121 is between the toggling member 121 and the roller 12;

[0064] After the film material 1121 is laid, lift the frame body 11 upward by using the air cylinder 15 (as shown in Figure ②), and rotate the toggling member 121 (as shown in Figure ③). At this time, the toggling member 121 rotates in the clockwise direction in the figure (rotating to the position labeled 2 in the figure), so that part of the film material 1121 is lifted above the cutting member 14, and there are two layers of film material 1121 at the cutting member 14 (one layer is the lifted film material close to the cutting member, and one layer is the film material adhering to the surface of the roller, and there is a set distance between the lifted film material and the film material adhering to the roller to prevent the cutting member from cutting the film material adhering to the roller when cutting the lifted film material);

[0065] Extend the telescopic member 13 (as shown in Figure ④), so that the telescopic member 13 abuts against the lifted film material 1121 and abuts against the film material 1121 adhering to the roller 12 through the groove 1211 of the arc-shaped plate and abuts against the roller 12, thereby fixing the film material 1121. Then move the cutting member 14 along the arrow direction, so that the heating wire of the cutting member 14 cuts the lifted film material 1121;

[0066] At this time, the frame body 11 can be moved to the next position where the film material 1121 is to be laid by using the power equipment, move the cutting member 14 (as shown in Figure ⑤) and rotate the toggling member 121 counterclockwise (so that the toggling member returns to the position labeled 1). Since the telescopic member 13 still abuts against the film material 1121 at this time, the film material 1121 has not been put down;

[0067] Lower the frame body 11 by using the air cylinder 15 (as shown in Figure ⑥), the roller is placed on the surface of the concrete, and part of the film material 1121 is pressed under the roller 12;

[0068] Shrink the telescopic member 13 (as shown in Figure ⑦), and the lifted film material 1121 falls onto the surface of the concrete due to gravity. The above steps can be repeated to carry out film covering.

[0069] The present invention has been described in detail in conjunction with the embodiments with reference to the accompanying drawings. Those of ordinary skill in the art can make various variations to the present invention according to the above description. Therefore, certain details in the embodiments should not constitute a limitation to the present invention, and the protection scope of the present invention will be defined by the scope defined in the appended claims.
