Description

Technical Field

[0001] This application relates to the field of concrete curing, and in particular to a concrete curing plastic film laying device. Background Technology

[0002] During concrete construction, the purpose of curing is to ensure that the concrete structure maintains suitable moisture conditions during the hardening process to promote the normal development of its strength. In the initial stage after concrete is poured, the surface moisture of the concrete is easily evaporated rapidly due to external environmental factors such as wind and temperature, resulting in the concrete surface drying too quickly and causing shrinkage cracks. This not only affects the aesthetics of the concrete but also reduces its overall structural strength and service life.

[0003] Currently, a common method used in concrete curing is laying a curing membrane. This membrane is typically made of plastic, offering good waterproofing and breathability, effectively slowing down the evaporation of moisture from the concrete surface and providing a relatively stable humidity environment. In practice, after the concrete is poured and initially leveled, workers quickly lay a layer of plastic film on its surface, minimizing gaps between the film and the concrete to ensure effective curing. This method is simple to operate, low in cost, and effectively protects the concrete surface from adverse environmental influences.

[0004] However, existing methods for laying curing membranes have a significant problem. Because concrete remains relatively soft for a period after pouring, workers often step on the concrete surface when laying the curing membrane. This inevitably leaves numerous footprints, disrupting the smooth surface and reducing the adhesion between the curing membrane and the concrete, creating localized gaps and affecting the membrane's protective effect. Furthermore, footprints can become potential starting points for cracks in the concrete surface, further increasing the risk of cracking. Utility Model Content

[0031] Exemplary embodiments will now be described more fully with reference to the accompanying drawings. However, these exemplary embodiments can be implemented in many forms and should not be construed as limited to the examples set forth herein; rather, these embodiments are provided to make the present invention more comprehensive and complete, and to fully convey the concept of the exemplary embodiments to those skilled in the art. The described features, structures, or characteristics may be combined in any suitable manner in one or more embodiments. In the following description, numerous specific details are provided to give a full understanding of the implementation of embodiments of the present invention.

[0032] In the concrete curing process, laying a curing membrane made of plastic material is a common and effective method. Its excellent waterproof and breathable properties successfully slow down the evaporation of moisture from the concrete surface, creating a curing environment with constant humidity. However, in practice, because concrete is soft in the initial stages of pouring, workers inevitably leave footprints on the concrete surface when laying the curing membrane. This not only disrupts the surface smoothness and reduces the adhesion between the curing membrane and the concrete, creating localized gaps and weakening the protective effect, but may also become a potential starting point for surface cracks, increasing the risk of cracking.

[0033] To address the aforementioned problems, this application provides a concrete curing plastic film laying device, referring to... Figures 1-4 As shown, this concrete curing plastic film laying device mainly consists of a film covering component 10, a fixing component 20, and an extension component 30.

[0034] The covering component 10 includes a plastic curing film 1 and a roller 2. The plastic curing film 1 is directly applied to the concrete surface. Its material has good waterproof and breathable properties, which can effectively slow down the evaporation of moisture from the concrete surface. The roller 2 serves as an auxiliary tool. The plastic curing film 1 is fitted over the outside of the roller 2, making it easy to roll and lay on the concrete surface, reducing damage caused by manual dragging.

[0035] The fixing component 20 mainly serves to support and fix the roller 2. The roller 2 is fitted onto the fixing component 20 to ensure that the roller remains stable during rolling. The fixing component 20 is further fixed to the crossbar 6, which serves as the main support structure of the entire device. Its length and strength can be designed according to specific construction requirements.

[0036] The extension assembly 30 includes a crossbar 6 and an extension rod 7. The extension rod 7 is located inside the crossbar 6 and is connected to the crossbar 6 via a sliding connection. By adjusting the length of the extension rod 7 extending beyond the crossbar 6, the working width of the entire device can be flexibly adjusted to adapt to concrete curing areas of different sizes.

[0037] In this embodiment, the concrete curing plastic film laying device is first fixed to the crossbar 6, ensuring that the roller 2 is fitted onto the fixed component 20 and can rotate smoothly. The length of the extension rod 7 is adjusted according to the width of the laying area to achieve the required working width. The plastic curing film 1 is gradually unfolded from the roller 2, ensuring it adheres tightly to the concrete surface. During the unfolding process, the rolling action of the roller 2 can be used to reduce damage and unevenness caused by manual dragging.

[0038] During installation, specialized tools (such as nails, clips, or tape) can be used to secure the curing membrane to the concrete edge or supports to prevent it from being blown away or shifting. Simultaneously, ensure that there is sufficient overlap between the plastic curing membrane sections to improve sealing. After installation, conduct a thorough inspection of the plastic curing membrane to ensure it is free of damage, bubbles, and wrinkles, and adheres tightly to the concrete surface. Local adjustments can be made if necessary.

[0039] This embodiment of the concrete curing plastic film laying device solves the problem of workers easily leaving footprints on the concrete surface when laying the curing film in actual operation. Specifically, the device uses the cooperation of roller 2 and fixing component 20 to achieve smooth rolling laying of the plastic curing film 1 on the concrete surface, avoiding damage and unevenness caused by manual dragging. At the same time, by adjusting the length of extension rod 7, the working width of the device can be flexibly adjusted to adapt to concrete curing areas of different sizes.

[0040] This device improves laying efficiency and quality, reduces damage and unevenness caused by manual dragging, and further enhances the adhesion between the curing membrane and the concrete, reducing the formation of local voids and improving the protective effect. The device reduces the risk of concrete surface cracking and extends the service life of the concrete. At the same time, the device is versatile and flexible, and can be applied to narrow or complex environments.

[0041] In some embodiments of this application, reference is made to Figure 3As shown, the fixing assembly 20 includes a support rod 3, a fixing plate 4, and a curing film winding roller 5. Specifically, the fixing plate 4 is fixed to one end of the support rod 3, forming a stable support structure. There are two support rods 3 and two fixing plates 4, which are symmetrically arranged at both ends of the curing film winding roller 5 to ensure the smooth rotation of the curing film winding roller 5. The curing film winding roller 5 passes through the ends of the two support rods 3 away from the fixing plate 4 and is used to hold the plastic curing film 1. The roller 2 is sleeved on the fixing assembly 20, and the structural stability of the entire device is achieved through the fixed connection between the fixing plate 4 and the crossbar 6.

[0042] Support rod 3 supports the entire fixing assembly 20 and roller 2, ensuring the stability of the device during the laying process. Fixing plate 4 connects support rod 3 and curing film winding roller 5, and achieves structural stability of the entire device by fixing it to crossbar 6. At the same time, the design of fixing plate 4 also takes into account the sleeve requirements of roller 2, ensuring that roller 2 can rotate smoothly.

[0043] The curing film winding roller 5 is used to place the plastic curing film 1, so that the plastic curing film 1 can be easily unfolded and recycled. At the same time, the rotation of the curing film winding roller 5 also drives the rotation of the roller 2, thereby realizing the rolling laying of the plastic curing film 1 on the concrete surface.

[0044] This embodiment, by specifying the structure of the fixing component 20, solves the problems that workers often encounter when laying the curing film, such as unstable rollers and inconvenient management of the curing film. Specifically, the design of the fixing component 20 enables the roller 2 to rotate smoothly, while the introduction of the curing film winding roller 5 facilitates the unfolding and recycling of the plastic curing film 1.

[0045] In practical use, the fixing component 20 is first fixed to the crossbar 6 via the support rod 3 and the fixing plate 4. Then, the curing film winding roller 5 is installed on the support rod 3. Next, the roller 2 is fitted onto the fixing component 20, and the length of the extension rod 7 is adjusted to suit the working width. Finally, the plastic curing film 1 is smoothly laid on the concrete surface by rolling the roller 2. This embodiment further improves the efficiency and stability of the concrete curing plastic film laying device, facilitates the management of the curing film, and enhances the adaptability of the device.

[0046] In some embodiments of this application, the crossbar 6 has through holes at both ends, and the extension rod 7 has a positioning pin. The extension rod 7 is connected to the crossbar 6 by a sliding connection. In use, the extension rod 7 can be pulled out, and the positioning pin will be inserted into the through hole near the extension rod 7 to fix the extension rod 7. At this time, the operator can hold the end of the extension rod 7 away from the crossbar 6 to lay the plastic curing film 1. After laying, the positioning pin can be pressed down to insert the extension rod 7 back into the crossbar 6, and the positioning pin will then be inserted into the through hole at the other end of the crossbar 6 to realize the storage and fixation of the extension rod 7.

[0047] This embodiment solves the problem of inconvenient adjustment of the working width of the device in actual operation by using the cooperation of through holes and positioning pins. Specifically, when it is necessary to adjust the working width, simply move the extension rod 7 to the appropriate position inside the crossbar 6, and then insert the positioning pin into the corresponding through hole. This design not only simplifies the adjustment process of the working width, but also improves the adjustment accuracy and stability.

[0048] In some embodiments of this application, the fixing plate 4 is U-shaped, allowing it to be nested on the crossbar 6. Screws are provided on the side of the fixing plate 4 near the support rod 3, forming a detachable connection between the fixing plate 4 and the crossbar 6. The fixing plate 4 can wrap around a portion of the crossbar 6 through its U-shaped opening, and then the fixing plate 4 is fastened to the crossbar 6 with screws, thus forming a fixed connection structure.

[0049] The detachable connection ensures stability while facilitating subsequent disassembly and maintenance. During use, the fixing plate 4 is nested onto the crossbar 6, and the stability and reliability of the connection are ensured by adjusting the tightness of the screws. The solution has a simple structure and is easy to implement, reducing manufacturing costs and installation difficulty.

[0050] In some embodiments of this application, the two ends of the curing film winding roller 5 are respectively connected to the support rod 3 via bearings. The inner ring of the bearing is sleeved on the end of the curing film winding roller 5, and the outer ring of the bearing is fixed to the support rod 3. The bearings allow the curing film winding roller 5 to rotate more flexibly on the support rod 3, while ensuring the smoothness and durability of the rotation.

[0051] By using bearings as connecting components, friction and wear during rotation are reduced, while rotational accuracy and stability are improved. Simultaneously, the inner and outer rings of the bearings fit tightly with the curing film winding roller 5 and the support rod 3, ensuring a strong and reliable connection. This results in a smoother laying process for the plastic curing film 1, improving the laying quality.

[0052] In some embodiments of this application, an axial elastic gasket is provided between the bearing and the curing film winding roller 5, and the thickness of the elastic gasket is 0.5-1mm. The elastic gasket mainly serves to buffer, dampen shocks, and provide axial positioning. It can absorb axial forces and vibrations caused by rotation, load changes, or installation errors, thereby protecting the bearing and the curing film winding roller 5 from unnecessary damage.

[0053] In practical applications, shims that are too thin may not provide sufficient cushioning, while shims that are too thick may increase rotational resistance and even affect the normal operation of the bearing. Therefore, setting the thickness of the elastic shim between 0.5 and 1 mm ensures sufficient cushioning and shock absorption without negatively impacting rotational performance.

[0054] Specifically, a lower limit of 0.5mm ensures that the gasket has a certain degree of elasticity, providing basic cushioning while avoiding installation difficulties or functional deficiencies due to excessive thinness. An upper limit of 1mm ensures that the gasket provides sufficient cushioning without increasing unnecessary rotational resistance or affecting bearing accuracy due to excessive thickness.

[0055] In some embodiments of this application, the edge of the plastic curing film 1 is provided with embedded nylon reinforcing ribs, and the cross-section of the reinforcing ribs is rectangular.

[0056] The plastic protective film 1 serves as the primary covering material, protecting various surfaces from dust, moisture, and other contaminants. However, traditional plastic protective films are often fragile at the edges, making them susceptible to tearing or abrasion. Nylon reinforcing ribs are embedded reinforcing structures made of nylon, a high-strength, wear-resistant, and chemically resistant synthetic fiber with excellent physical and chemical properties. By embedding nylon reinforcing ribs into the edges of the plastic protective film 1, the strength and durability of that area can be significantly improved.

[0057] Traditional plastic protective films are prone to damage at the edges, which not only affects their service life but may also reduce their protective effect. This embodiment effectively solves this problem by introducing nylon reinforcing ribs. In practical use, the plastic protective film 1 is laid on surfaces requiring protection, such as construction sites, machinery, or furniture. Because of the embedded nylon reinforcing ribs at the edges, the edges of the protective film are less prone to tearing or wear when subjected to external forces, such as wind, rain, or human trampling. This not only extends the service life of the protective film but also ensures its long-term protective effect. The rectangular cross-section design of the reinforcing ribs provides additional support and strength, making the edges of the plastic protective film 1 more robust and durable.

[0058] In some embodiments of this application, the outer side of the crossbar 6 is provided with a guide groove, the length of which is greater than the width of the plastic curing film 1; the guide groove and the outer surface of the crossbar 6 have a gap, the gap being greater than the thickness of the plastic curing film 1, and the edge of the plastic curing film 1 passes through the gap.

[0059] The guide groove ensures that the plastic curing membrane 1 can move smoothly along the predetermined path during the laying process, avoiding misalignment and wrinkles. At the same time, the guide groove also serves to fix the edges of the plastic curing membrane 1, preventing it from moving under wind or other external forces. The gap allows the plastic curing membrane 1 to easily pass through and embed itself in the guide groove without causing wear or tear due to excessive tight contact.

[0060] Traditional methods for laying plastic curing films often suffer from uneven laying, misalignment, and difficulty in securing them. This embodiment effectively solves these problems by introducing a crossbar 6 and its outer guide groove design. The guide groove not only provides a clear laying path for the curing film but also ensures its stability and firmness through its limiting function. Simultaneously, the gap design makes the laying process smoother and avoids damage caused by friction.

[0061] In some embodiments of this application, ball bearings are provided on the inner sidewall of the guide groove facing the crossbar 6, and the ball bearings are in contact with the side of the plastic curing film 1 laid on the concrete.

[0062] The ball bearings are in direct contact with the plastic curing film 1, forming a low-friction rolling interface. This further reduces the resistance of the plastic curing film 1 during movement. Due to the presence of the ball bearings, the plastic curing film 1 can slide easily during the laying process without excessive manual pulling or adjustment, thus simplifying the laying process and protecting the plastic curing film 1.

[0063] The combined use of guide grooves and ball bearings ensures the flatness and stability of the plastic curing film 1, preventing misalignment and wrinkles. At the same time, due to the simplified laying process and increased efficiency, this embodiment can significantly save labor and time costs.

[0064] In some embodiments of this application, the side wall of the crossbar 6 is provided with scale lines distributed along the length direction, the spacing between the scale lines is 10cm, and the outer surface of the extension rod 7 is provided with indicator marks corresponding to the scale lines.

[0065] The scale lines make the crossbar 6 an intuitive and accurate measuring tool, while the indicator marks ensure the consistency of measurements after the extension bar and the crossbar are connected. This not only simplifies the laying process but also improves the accuracy and efficiency of the laying. Based on the width of the laying site and the required laying position, pull out the extension bar 7, find the corresponding scale line position on the crossbar 6, fix the extension bar 7, align the edge of the plastic curing film 1, and lay it along the guide groove.

[0066] The scale lines and indicator marks in this embodiment simplify the measurement and positioning steps during the laying process, reducing the difficulty and complexity of laying. Because measurement and positioning become simpler and more accurate, the laying process is accelerated, thereby improving laying efficiency. Furthermore, by connecting the extension rod 7, this embodiment allows for flexible adjustment of the entire laying system's length to adapt to laying areas of different sizes.

[0067] As described above, the concrete curing plastic film laying device provided in this application utilizes a roller-assisted laying component, reducing the opportunity for direct manual contact with the concrete surface; the fixing component ensures the stability and accuracy of the curing film during laying; and the extension component, through a sliding connection and positioning pin design, allows for flexible adjustment of the crossbar length, facilitating storage and use. Furthermore, the guide groove and ball bearing design further reduce frictional resistance during laying, protecting the curing film from damage. The introduction of scale lines and indicator marks provides intuitive and accurate measuring tools, ensuring the precision and efficiency of laying. The nylon reinforcing ribs enhance the strength and durability of the curing film edges, extending its service life. This device effectively solves the problems existing in the prior art, improves the precision and efficiency of laying, protects the integrity of the concrete surface, and reduces the risk of cracking, demonstrating significant beneficial effects.
