Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of building construction, in particular to a ground film laying device for a construction project. Background Art
[0002] Construction projects are a general term for all types of buildings and engineering facilities that provide the material and technological foundation for human life and production. Construction projects are organized, purposeful, and large-scale economic activities. Based on their physical attributes, construction projects can be categorized into three types: architectural engineering, civil engineering, and mechanical and electrical engineering. Construction projects are organized, purposeful, and large-scale economic activities. They are engineering projects that generate comprehensive production capacity or maximize project benefits during the reproduction of fixed assets. Construction projects refer to the construction of new or the renovation of existing fixed assets.
[0003] In the construction field, the protection measures for newly poured concrete products of floors and sidewalks are different due to the different maintenance methods selected for the different film coverage areas. The traditional workers' plastic film laying process, insulation measures are difficult to control, edge pressing is not in place, and plastic film is easily damaged, which reduces the maintenance of concrete products.
[0004] Traditional workers laying plastic film is also affected by the size of the coverage area. If the floor coverage area is large, workers walking on the newly poured surface may easily disturb the final setting of the finished concrete or damage the plastic film during the covering process. Utility Model Content
[0005] The purpose of the present invention is to overcome the problems raised in the above-mentioned background technology and provide a ground film laying device for construction projects, which improves construction efficiency, is simple to operate, has high flexibility, and improves the maintenance measures of the film on the construction access road and floor concrete surface.
[0006] The purpose of this utility model is mainly achieved through the following technical solutions:
[0007] A ground film laying device for construction projects comprises a support rod, a roller disposed below the support rod, the roller being connected to the support rod and capable of rotating about its own axis; a connecting arm connected to the support rod, a roller being disposed at one end of the connecting arm remote from the support rod and capable of rotating about its own axis; a water guide tube disposed on the exterior of the support rod, a connecting rod disposed between the water guide tube and the support rod, the ends of the connecting rod being fixed to the water guide tube and the support rod, respectively; a plurality of nozzles disposed on the outer wall of the water guide tube, and the nozzles being connected to the interior of the water guide tube. In the construction industry, the protection measures for newly cast concrete products on floors and sidewalks vary depending on the area covered by the film. However, traditional workers' processes for laying plastic film result in problems such as difficulty controlling insulation measures, inadequate edge pressing, and easy damage to the plastic film, which reduces the curing efficiency of the finished concrete products. Traditional workers' methods for laying plastic film are also affected by the size of the coverage area. If the floor coverage area is large, workers walking on the newly cast surface can easily disturb the final setting of the finished concrete or damage the plastic film during the covering process. At the same time, watering and maintenance are required after covering the film. Currently, watering is done manually with a water pipe after covering the film. The watering force and position are different, making it difficult to achieve uniform watering. At the same time, the surface of the newly covered concrete is soft. If the watering force is not properly controlled, the concrete surface will be damaged, affecting the quality. In order to solve the above problems, this scheme designs a ground film laying device for construction projects, including a support rod. The support rod adopts an internal hollow metal tube and is a steel body that supports the overall structure. A roller is provided under the support rod. The roller and the support rod are connected to form an overall structure by a short tube. The roller can rotate around its own axis, and the plastic film is wrapped around the roller. A connecting arm is connected to the support rod. A roller is provided at the end of the connecting arm away from the support rod, and the roller can rotate around its own axis. The roller is used to realize the movement of the device, thereby improving the moving speed. Moreover, the roller can also press the edge of the unfolded plastic film when moving, without the need for workers to cooperate in pressing the edge, thereby improving construction efficiency. A water guide cylinder is arranged outside the support rod, and a connecting rod is arranged between the water guide cylinder and the support rod. Both ends of the connecting rod are fixed to the water guide cylinder and the support rod respectively. A number of nozzles are arranged on the outer wall of the water guide cylinder, and the nozzles are connected with the inside of the water guide cylinder. A water pipe can be introduced into the end of the water guide cylinder to spray water evenly on the unfolded film through the nozzles to cool the concrete. Moreover, the spraying is uniform throughout the whole process and the spraying intensity can also be controlled, thereby protecting the integrity of the concrete surface and improving the quality of the concrete. The equipment is simple to operate and highly flexible, and improves the maintenance measures of the film on the construction access road and floor concrete surface.
[0008] Furthermore, since it is necessary to move continuously along the concrete surface, a component that is easy for manual gripping needs to be provided. The support rod is not convenient to operate, so a guide rod is provided on the water guide cylinder, and one end of the guide rod is fixed to the water guide cylinder, and the other end is fixed to the support rod and extends above the support rod, and a cross rod is provided on the part above the support rod, and the cross rod is fixed vertically to the two guide rods at the same time. The cross rod makes it easy for workers to hold up the device, making it easier to pull open the plastic film on the drum, and at the same time the center of gravity of the equipment is lowered, which is more labor-saving when moving. At the same time, the guide rod is located between the connecting rods to stabilize the center of gravity and evenly distribute the force.
[0009] Furthermore, it is best to locate the roller between the longitudinal areas of the drum so that when the plastic film is unfolded, the roller always rotates on the plastic film. According to the width calculation, the wheel surface of the roller is just at the edge of the plastic film.
[0010] Furthermore, the rollers are positioned between the connecting arms and the connecting rod, each with a connecting shaft. The shaft passes through both ends of the rollers and connects to the connecting arms and the connecting rod, respectively. The rollers are capable of rotating about the shaft axis. This structural design allows the rollers to remain stable and their movement paths to lie in a straight line, thereby compacting and tightening the plastic film.
[0011] In summary, compared with the existing technology, the utility model has the following beneficial effects: the utility model can introduce a water pipe at the end of the water guide tube, and spray water evenly on the unfolded film through the nozzle to achieve cooling of the concrete. Moreover, the spraying is uniform throughout the entire process, and the spraying intensity can also be controlled, thereby protecting the integrity of the concrete surface and improving the quality of the concrete. The equipment is simple to operate and highly flexible, and improves the maintenance measures of the film on the construction access road and floor concrete surface. BRIEF DESCRIPTION OF THE DRAWINGS

[0017] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.
[0018] In the description of the present invention, it needs to be understood that the directions or positional relationships indicated by directional words such as "front, back, up, down, left, right", "horizontal, vertical, vertical, horizontal" and "top, bottom" are usually based on the directions or positional relationships shown in the drawings. They are only for the convenience of describing the present invention and simplifying the description. Unless otherwise specified, these directional words do not indicate or imply that the device or element referred to must have a specific direction or be constructed and operated in a specific direction. Therefore, they cannot be understood as limiting the scope of protection of the present invention; the directional words "inside and outside" refer to the inside and outside relative to the outline of each component itself.
[0019] In addition, it should be noted that the use of words such as "first" and "second" to limit components is only for the convenience of distinguishing the corresponding components. Unless otherwise stated, the above words have no special meaning and therefore cannot be understood as limiting the scope of protection of this utility model.
[0020] like Figure 1 and Figure 2 As shown, a ground film laying device for construction projects in this embodiment provides an effective plastic film covering method to meet the maintenance measures of most floor slabs, basement floors, sidewalks, ramps, roofs and other concrete finished products. An internal hollow support rod 1 is used as the main supporting component of the entire device, and a roller 3 is provided under the support rod 1. The roller 3 and the support rod 1 are connected to form an integral structure through a short tube. The roller 3 can rotate around its own axis, and the plastic film 7 is wound on the roller 3. First, a concrete surface 9 is laid on the ground 8, and then the end of the plastic film 7 is pulled out and attached to the concrete surface 9. As the device moves, the plastic film 7 can be automatically pulled out and attached to the concrete surface 9. The roller 3 can rotate around its own axis, thereby realizing automatic bonding, and the bonding efficiency is also high, thereby improving construction efficiency.
[0021] Connecting arms 10 are attached to support rods 1. Rollers 5 are positioned at the ends of connecting arms 10 facing away from support rods 1. These rollers 5 are capable of rotating about their own axes. The width of the plastic film 7 is slightly wider than the rollers 5 on either side. The starting point of the roll is the film's covering point. During roll operation, the rollers 5 press the edges of the plastic film 7 on both sides of the width, eliminating the need for workers to perform the press. Rollers 5 are positioned between the longitudinal sections of drum 3. This ensures that as the plastic film 7 is unrolled, the rollers 5 always rotate over the film 7. Based on the optimal width calculation, the rollers 5's wheel surfaces precisely align with the edges of the film 7.
[0022] A water guide tube 6 is disposed outside the support rod 1. A connecting rod 4 is disposed between the water guide tube 6 and the support rod 1. The ends of the connecting rod 4 are fixed to the water guide tube 6 and the support rod 1, respectively. Several nozzles are disposed on the outer wall of the water guide tube 6, and the nozzles are connected to the interior of the water guide tube 6. A water pipe can be introduced into the end of the water guide tube 6, and water is evenly sprayed onto the unfolded film through the nozzles to cool the concrete. The entire spraying process is uniform and the spraying intensity can be controlled, thereby protecting the integrity of the concrete surface and improving concrete quality. The equipment is simple to operate and highly flexible, and improves the maintenance measures for the film on the construction access road and floor concrete surface.
[0023] Since it is necessary to move continuously along the concrete surface, a component that is easy for manual gripping is required. The support rod 1 is not easy to operate, so a guide rod 2 is provided on the water guide cylinder 6, and one end of the guide rod 2 is fixed to the water guide cylinder 6, and the other end is fixed to the support rod 1 and extends above the support rod 1, and a cross bar is provided on the part above the support rod 1, and the cross bar is fixed vertically to the two guide rods 2 at the same time. The cross bar makes it easy for workers to hold up the device, making it easier to pull open the plastic film 7 on the roller 5. At the same time, the center of gravity of the equipment is lowered, and it is more labor-saving when moving. At the same time, the guide rod 2 is located between the connecting rods 4, so that the center of gravity is stable and the force is evenly distributed.
[0024] The rollers 5 are positioned between the connecting arms 10 and the connecting rod 4. A connecting shaft extends through each end of the roller 5, connecting to the connecting arms 10 and the connecting rod 4, respectively. The rollers 5 are capable of rotating about the shaft's axis. This structural design ensures that the rollers 5 remain stable and their movement trajectory lies in a straight line, compacting and tightening the plastic film 7. The film rotates synchronously with the rollers under the tension of the paving, achieving efficient film laying.
