Description

Technical Field

[0001] The invention relates to the technical field of building construction, in particular to a ground membrane laying device for a building project. Background Art

[0002] Construction engineering is a general term for various buildings and engineering facilities that provide material and technical basis for human life and production. Construction engineering is an organized, purposeful, large-scale economic activity of human beings. According to their natural attributes, construction engineering can be divided into three categories: construction engineering, civil engineering and electromechanical engineering. Construction engineering is an organized, purposeful, large-scale economic activity of human beings. It is an engineering project that forms comprehensive production capacity or exerts engineering benefits in the process of fixed asset reproduction. Construction engineering refers to the construction of new or the transformation 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' process of laying plastic film, the insulation measures are difficult to control, the edge pressing is not in place, and the plastic film is easily damaged, which reduces the maintenance of the concrete products.

[0004] Traditionally, workers lay plastic film, which 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. Summary of the invention

[0005] The purpose of the present invention is to overcome the problems raised in the above-mentioned background technology and provide a device for laying ground membrane in 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 the present invention is mainly achieved through the following technical solutions:

[0007] A ground film laying device for construction engineering includes a support rod, a roller is arranged below the support rod, the roller is connected to the support rod and can rotate around its own axis; a connecting arm is connected to the support rod, a roller is arranged at one end of the connecting arm away from the support rod, and the roller can rotate around its own axis; a water guide cylinder is arranged outside the support rod, a connecting rod is arranged between the water guide cylinder and the support rod, the two ends of the connecting rod are respectively fixed to the water guide cylinder and the support rod, and a plurality of nozzles are arranged on the outer wall of the water guide cylinder, and the nozzles are connected to the inside of the water guide cylinder. In the field of construction, the protection measures for the finished products of newly poured concrete on floors and walkways are different due to the different coverage areas of the film. However, the traditional workers' laying of plastic film technology, insulation measures are difficult to control, the edge pressing is not in place, and the plastic film is easy to break, which reduces the maintenance of the finished concrete. The traditional workers' laying of plastic film is also affected by the size of the coverage area. If the coverage area of ​​the floor is large, workers walking on the newly poured surface are easy to disturb the final setting of the finished concrete or damage it during the covering process of the plastic film. At the same time, watering and maintenance are required after film covering. At present, watering is done manually with a water pipe after film covering. The watering strength and position are different, and it is difficult to achieve uniform watering. At the same time, the surface of the newly covered concrete is soft. If the watering strength is not properly controlled, the concrete surface will be incomplete, 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, which is a steel body supporting the overall structure. A roller is arranged under the support rod. The roller and the support rod are connected to the overall structure through 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 arranged at the end of the connecting arm away from the support rod, and the roller can rotate around its own axis. The device is moved by the roller, thereby improving the moving speed. Moreover, the roller can also press the edge of the unfolded plastic film when moving, and workers do not need to cooperate in pressing the edge, thereby improving construction efficiency. A water guide cylinder is arranged outside the support rod, a connecting rod is arranged between the water guide cylinder and the support rod, two ends of the connecting rod are respectively fixed to the water guide cylinder and the support rod, a plurality 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, and water can be evenly sprayed on the unfolded film through the nozzles to achieve cooling of the concrete, and the whole process is sprayed evenly, and the spraying intensity can also be controlled, so as to protect the integrity of the concrete surface and improve the quality of the concrete. The equipment is simple to operate and highly flexible, and the maintenance measures of the film on the construction access road and floor concrete surface are improved.

[0008] Furthermore, since it is necessary to move continuously along the concrete surface, a component that is easy for manual holding 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 then extends above the support rod, and a cross bar is provided on the part above the support rod, and the cross bar is vertically fixed to the two guide rods at the same time. The cross bar is convenient for workers to hold up the device, so that the plastic film on the drum is easier to be pulled open, and 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 preferred to locate the roller between the longitudinal regions of the drum, so that when the plastic film is unfolded, the roller always rotates on the plastic film, and the wheel surface of the roller is just located at the edge of the plastic film according to the width calculation.

[0010] Furthermore, the rollers are respectively located between the connecting arms and the connecting rods, and the rollers are provided with connecting shafts, which pass through both ends of the rollers and are respectively connected to the connecting arms and the connecting rods, and the rollers can rotate around the axis of the connecting shafts. With this structural design, the rollers can remain stable, and their moving tracks are located in a straight line, so that the plastic film can be compacted and pressed.

[0011] In summary, compared with the prior art, the present invention has the following beneficial effects: the present invention 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, and the whole process is sprayed evenly, and the spraying intensity can also be controlled, thereby protecting the integrity of the concrete surface and improving the quality of 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.

[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 concrete finished products such as most floor slabs, basement floors, sidewalks, ramps, roofs, etc., and adopts an internal hollow support rod 1 as the main supporting component of the entire device. A roller 3 is arranged 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. 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] By connecting the connecting arm 10 to the support rod 1, the connecting arm 10 is provided with a roller 5 at one end away from the support rod 1, and the roller 5 can rotate around its own axis, the width of the plastic film 7 is slightly wider than the rollers 5 on both sides, and the starting point of the driving is the starting point of the film covering. During the driving process, the two sides of the plastic film 7 in the width direction are rolled and pressed by the rollers 5, and workers do not need to cooperate in pressing the edges. The roller 5 is located between the longitudinal areas of the drum 3. In this way, when the plastic film 7 is unfolded, the roller 5 rotates and is always located on the plastic film 7. According to the optimal width calculation, the wheel surface of the roller 5 is just located at the edge of the plastic film 7.

[0022] A water guide tube 6 is arranged outside the support rod 1, a connecting rod 4 is arranged between the water guide tube 6 and the support rod 1, and the two ends of the connecting rod 4 are respectively fixed to the water guide tube 6 and the support rod 1, and a plurality of nozzles are arranged on the outer wall of the water guide tube 6, and the nozzles are connected with the inside of the water guide tube 6. A water pipe can be introduced at the end of the water guide tube 6, and water can be evenly sprayed on the unfolded film through the nozzle to achieve cooling of the concrete, and the whole process is sprayed evenly, and the spraying intensity can also be controlled, so as to protect the integrity of the concrete surface and improve the quality of the concrete. The equipment is simple to operate and highly flexible, and the maintenance measures of the film on the construction access road and floor concrete surface are improved.

[0023] Since it is necessary to move continuously along the concrete surface, a component that is easy for manual holding 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 vertically fixed to the two guide rods 2 at the same time. The cross bar is convenient for workers to hold up the device, so that the plastic film 7 on the drum 5 is easier to be pulled open, and the center of gravity of the equipment is lowered, which 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 respectively located between the connecting arms 10 and the connecting rods 4. The rollers 5 are provided with connecting shafts. The connecting shafts pass through the two ends of the rollers 5 and are respectively connected to the connecting arms 10 and the connecting rods 4. The rollers 5 can rotate around the axis of the connecting shafts.
