Description

Technical Field

[0001] This application relates to the field of waterproof membrane laying technology, and in particular to a device for preventing edge curling during waterproof membrane laying. Background Technology

[0002] In the field of building waterproofing engineering, traditional waterproof membrane laying operations face numerous technical challenges. On the one hand, manual laying of waterproof membranes relies heavily on workers manually rolling and compacting them, which is not only labor-intensive and inefficient but also makes it difficult to ensure the adhesion between the membrane and the substrate, easily leading to problems such as curling edges and wrinkles, affecting the waterproofing effect and project quality. On the other hand, existing mechanical laying equipment suffers from limitations in functionality and adaptability: some equipment only has simple membrane laying functions and lacks methods to clean excess adhesive and debris from the membrane surface, resulting in an uneven surface and reduced adhesion; while equipment with scraping structures often uses a rigid contact design, which cannot adapt to the unevenness of the substrate surface, easily leading to over-scraping or uneven scraping, or even damage to the membrane surface. In addition, most equipment is difficult to flexibly adjust the working angle and pressure, making it difficult to meet diverse laying needs when constructing on complex terrain or irregular structures, thus restricting the construction efficiency and quality improvement of waterproofing projects.

[0003] The information disclosed in this background section is only intended to enhance the understanding of the background technology of this application, and therefore may include prior art that is not known to those skilled in the art. Utility Model Content

[0004] To address the issue that manual installation of waterproof membrane relies heavily on workers rolling and compacting the material, which is not only labor-intensive and inefficient but also makes it difficult to ensure the adhesion between the membrane and the substrate, easily leading to problems such as curling and wrinkles, this application provides a device to prevent curling during waterproof membrane installation.

[0012] In summary, this application includes the following beneficial technical effects:

[0013] This application utilizes a combination of pusher, connecting arm, and mounting bracket, along with pulleys, to enable the laying vehicle to move and steer flexibly in complex environments.

Detailed Implementation

[0018] The following is in conjunction with the appendix Figure 1-3 This application will be described in further detail.

[0019] This application discloses a device for preventing edge curling during the laying of waterproof membrane. (Refer to...) Figures 1-2The system includes a laying vehicle 1, with a mounting frame 3 rotatably mounted on its top. A connecting arm 4 is connected to the middle of the mounting frame 3, and a pusher 5 is fixed to the top of the connecting arm 4. Pulleys 2 are connected to both sides of the laying vehicle 1, and a movable cavity 8 is formed at the bottom of the laying vehicle 1. A set of rotating shafts 6 are rotatably connected to the inner wall of the movable cavity 8, and anti-warping smoothing rollers 7 are fixed to the outside of the rotating shafts 6. The pusher 5, connecting arm 4, and mounting frame 3 allow operators to flexibly adjust the angle of the laying vehicle 1, enabling flexible steering and movement of the equipment in complex construction environments, significantly improving laying efficiency. The anti-warping smoothing rollers 7, through the rotation design of the rotating shafts 6, automatically roll and compress the roll material during the movement of the laying vehicle 1, requiring no additional power drive. This simplifies the operation process while ensuring a tight fit between the roll material and the substrate, effectively preventing warping.

[0020] like Figure 3 As shown, brackets 12 are fixed on both sides of the inner wall of the movable cavity 8, and movable scrapers 16 are connected inside the brackets 12. Mounting components 11 are symmetrically welded to the outer wall of the top of the laying vehicle 1. A screw 9 is threadedly connected to the inner wall of the mounting component 11, and the bottom end of the screw 9 is movably connected to the top of the scraper 16. Sliding grooves 10 adapted to the scraper 16 are provided in the middle of both sides of the laying vehicle 1. The threaded adjustment structure of the screw 9 and the scraper 16 allows for control of the distance between the scraper 16 and the surface of the waterproof membrane. The scraping force can be flexibly adjusted according to construction needs, effectively removing excess adhesive and debris, ensuring a smooth membrane surface, providing an ideal foundation for subsequent bonding processes, and improving the quality of waterproof construction.

[0021] In this application, the inner wall of the support 12 is symmetrically provided with inner grooves 13. A matching sliding block 15 is slidably mounted inside the inner groove 13. A spring 14 connects the sliding block 15 to the inner wall of the inner groove 13. One end of the sliding block 15 extends outside the inner groove 13 and is fixed to the outer wall of the scraper 16. The buffer system composed of the sliding block 15, spring 14, and inner groove 13 gives the scraper 16 adaptive adjustment capability. When encountering uneven substrates or changes in resistance, the compression and rebound of the spring 14 can adjust the contact pressure of the scraper 16 in real time, avoiding equipment damage caused by rigid contact and ensuring the continuity and stability of the scraping operation, significantly enhancing the equipment's adaptability to complex construction environments.

[0022] The implementation principle of the waterproof membrane laying anti-curling device in this application embodiment is as follows:

[0023] In use, the angle of the mounting frame 3 can be adjusted by operating the connecting arm 4 of the hand-held pusher 5, which allows the laying vehicle 1 to move flexibly on the ground. When the laying vehicle 1 moves on the waterproof membrane, the anti-curling smoothing roller 7 rotates outside the rotating shaft 6 under frictional force, rolling and squeezing the waterproof membrane to fully adhere it to the base surface, while smoothing out any wrinkles on the surface of the membrane to prevent curling.

[0024] After the initial rolling and pressing, the screw 9 is rotated again. As the screw 9 moves up and down, it causes the scraper 16 to slide up and down within the groove 10, thereby adjusting the distance between the scraper 16 and the surface of the waterproof membrane. When the scraper 16 descends to the appropriate position, during the movement of the laying vehicle 1, the scraper 16 can remove excess adhesive or debris from the surface of the waterproof membrane, making the surface of the membrane smoother and facilitating the adhesion of the membrane and preventing edge curling.

[0025] Furthermore, during the movement of the scraper 16, the sliding block 15 simultaneously slides and compresses the spring 14 within the inner groove 13. When the scraper 16 encounters an uneven surface or significant resistance during operation, it experiences a reaction force. At this time, the sliding block 15 slides within the inner groove 13 and compresses the spring 14. The spring 14 acts as a buffer, preventing the scraper 16 from being damaged by excessive impact. It also ensures that the scraper 16 maintains appropriate contact pressure with the surface of the waterproof membrane, ensuring effective scraping.
