Description

Technical Field

[0001] The present invention relates to the technical field of building construction, and specifically to a concrete floor curing device. Background Art

[0002] When curing a concrete floor, workers need to lay a plastic film on the concrete floor. When the plastic film is wrapped around the concrete floor, it can reduce the evaporation rate of water in the concrete and prevent the concrete from cracking prematurely. After the plastic film is laid on the concrete floor, workers need to spray water on the plastic film. When the concrete floor is firmly formed, workers need to tear off the plastic film on the concrete floor. The common methods of tearing off the plastic film on the market are mainly that construction workers use a rake or palm to tear off the plastic film on the concrete floor. This method can indeed achieve a good tearing effect on the plastic film on the concrete floor, but in the actual use process, there are still some deficiencies: 1. When using a rake or palm to tear off the plastic film on the concrete floor, it is easy to cause the plastic film to be damaged. The damaged plastic film is not easy to clean and transport, and it is also easy for the damaged plastic film to adhere to the concrete floor, which is not convenient for workers to cure the concrete floor subsequently; 2. When the plastic film is wrapped around the concrete floor, the plastic film is easy to adhere to concrete, and these concretes will solidify into concrete blocks. When construction workers tear off the plastic film wrapped around the concrete floor, it is easy for the concrete on the plastic film to splash. The splashed concrete will not only pollute the concrete floor, but also easily scratch the construction workers; 3. When the plastic film is wrapped around the concrete floor, there will be air bubbles between the concrete floor and the plastic film. These air bubbles will affect the curing effect of the plastic film on the concrete floor and are also easy to cause the plastic film to be damaged.

[0003] Therefore, we propose a concrete floor curing device. Summary of the Invention

[0021] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0022] Embodiment 1: Please refer to Figures 1-6 , the present invention provides a technical solution: A concrete floor curing device includes a bracket structure 3 and a first conveying structure 1 and a second conveying structure 2 distributed on the bracket structure 3. The first conveying structure 1 and the second conveying structure 2 can drive the plastic film on the concrete floor to separate from the concrete floor. It further includes: An abutting structure 4, which is distributed at the collection ends of the first conveying structure 1 and the second conveying structure 2. The abutting structure 4 can abut against the plastic film covering the concrete floor. A water spraying pipe 6 is distributed above the first conveying structure 1 and the second conveying structure 2. The water spraying pipe 6 can spray water on the plastic film abutted by the abutting structure 4. A pushing structure 5 is fixedly connected to the water spraying pipe 6; During the actual use of the maintenance device, the staff can drive the water spray pipe 6 to move back and forth through the pushing structure 5. Subsequently, the water receiving end of the water spray pipe 6 is connected to an external pump, and the water spray pipe 6 can spray water on the concrete floor slab; Embodiment 2: Please refer to Figure 1 , 2 , 4-6, 9-11. The present invention provides a technical solution: The abutting structure 4 includes a rolling column 41 and an elastic strip 45 fixedly connected to the rolling column 41. The rolling column 41 can cooperate with the elastic strip 45 to form a sealed columnar cavity structure. Rotating tubes 44 are fixedly connected to both ends of the rolling column 41, and a pushing plate 42 is rotatably connected to the rotating tubes 44; When air is injected into the rolling column 41, the elastic strip 45 can be squeezed and expanded. At this time, the elastic strip 45 can cooperate with the rolling column 41 to form a smooth columnar cavity structure, and the rolling column 41 can drive the elastic strip 45 to roll the plastic film on the surface of the concrete floor slab, which can prevent air from existing between the concrete floor slab and the plastic film. When the air inside the rolling column 41 is discharged, the elastic strip 45 is no longer squeezed. At this time, the elastic strip 45 and the rolling column 41 form a non-smooth columnar cavity structure. When the rolling column 41 rotates, it can cooperate with the elastic strip 45 to lift the plastic film, and the separation of the plastic film from the concrete floor slab can be realized.

[0023] Embodiment 3: Please refer to Figures 1-5 , the present invention provides a technical solution: The structures of the first conveying structure 1 and the second conveying structure 2 are the same.

The second push wheel 11 includes a push wheel structure 111 and an elastic sheet 117 fixedly connected to the push wheel structure 111. The push wheel structure 111 can also cooperate with the elastic sheet 117 to form a sealed columnar cavity structure; A rotating tube 44 is also fixedly connected to the push wheel structure 111. The rotating tube 44 on the push wheel structure 111 penetrates through the support structure 3, and the rotation of the push wheel structure 111 on the support structure 3 can be realized. An end air cap 113 is fixedly connected to the rotating tube 44 on the push wheel structure 111, a connecting tube 114 is fixedly connected to the end air cap 113, and an extrusion air bag 112 is fixedly connected to the end of the connecting tube 114 away from the end air cap 113; When the extrusion airbag 112 is squeezed, the air inside the extrusion airbag 112 can enter the inside of the push wheel structure 111 through the connecting pipe 114. When the elastic piece 117 is squeezed and expanded, the elastic piece 117 can form a smooth columnar cavity structure with the push wheel structure 111, which can prevent the second push wheel 11 and the first push wheel 9 from damaging the plastic film. When the elastic piece 117 resets, the elastic piece 117 can contract. At this time, the surfaces of the second push wheel 11 and the first push wheel 9 are recessed, which can increase the friction between the second push wheel 11 and the first push wheel 9 and the ground.

Pressing gears 124 are fixedly connected to both ends of the first roller 123, and the transmission gear 121 and the pressing gears 124 are meshed.

[0026] The inner sides of the pressing gears 124 and the transmission gear 121 are not in contact with the belt structure 25. A swing rod 128 is sleeved between the transmission gear 121 and the second roller 125 on the transmission end column 127.

A fixing rod 82 is fixedly connected to the gas collecting structure 8. The gas collecting structure 8 is fixedly connected to the water spraying pipe 6 through the fixing rod 82. The gas collecting structure 8 is a hollow structure. The first valve 81, the second valve 83 and the limiting rod 84 are distributed at the part of the gas collecting structure 8 close to the gas guide pipe 43. The inner cavity of the gas collecting structure 8 is communicated with the inner cavity of the gas guide pipe 43 by using the first valve 81 and the second valve 83. When the hand of the staff drives the water spray pipe 6 to move forward through the pushing structure 5, the bottom of the air collecting structure 8 can slide on the air guide pipe 43. At this time, the upper end of the air guide pipe 43 abuts against the second valve 83, and the air inside the air collecting structure 8 can be transported to the inside of the air guide pipe 43 through the second valve 83.
