Description

Technical Field

[0001] This utility model relates to the technical field of waterproof membrane laying tools, and in particular to a modified bitumen waterproof membrane scraping device. Background Technology

[0002] Modified bitumen waterproof membrane is made from bitumen as a base material, with the addition of rubber and resin modifiers, through a mixing and calendering process. It improves upon the defects of traditional bitumen, such as low-temperature brittleness and high-temperature flow, and also possesses good weather resistance, ductility, and adhesion.

[0003] When laying this type of roll material, the adhesive must be evenly applied to the installation surface using a scraper. Only in this way can a continuous and uniform adhesive layer be formed, ensuring a tight bond between the waterproof roll material and the substrate. This avoids air pockets and bubbles caused by uneven adhesive distribution, thereby enhancing the overall stability of the waterproof system and reducing the risk of leakage.

[0004] However, in existing technologies, it is difficult to consistently control the applied force and scraping angle when manually operating a hand-held scraper. During operation, the force applied by the hand fluctuates due to changes in physical strength and differences in application habits, resulting in uneven adhesion pressure between the scraper and the substrate. This leads to deviations in the thickness of the adhesive in different areas, with thinner adhesive layers in areas of high pressure and thicker adhesive layers in areas of low pressure, ultimately failing to ensure uniform overall thickness. Utility Model Content

[0005] The purpose of this invention is to address the problem in the existing technology where, when manually operating a hand-held scraper, it is difficult to stably control the force and angle due to differences in physical strength and application habits, resulting in uneven bonding pressure and deviations in adhesive thickness (thinner adhesive layer where the pressure is high and thicker adhesive layer where the pressure is low), thus failing to ensure overall uniformity. The invention proposes a modified bitumen waterproof membrane scraping device.

[0006] The technical solution of this utility model is as follows: a modified bitumen waterproof membrane coating device, including a coating plate, and further including: a coating pad fixedly connected to the coating plate, a U-shaped rod provided on the coating plate, and a rolling mechanism provided at both ends of the U-shaped rod; an adjustment mechanism provided in the middle of the coating plate and the U-shaped rod, the adjustment mechanism being used to move the rolling mechanism up and down; and a limiting ruler plate installed on the coating plate corresponding to the adjustment mechanism.

[0007] Optionally, the adjusting mechanism includes a spiral support plate fixedly sleeved in the middle of the U-shaped rod, and a spiral rod that spirally passes through the spiral support plate is rotatably connected to the middle of the scraper plate. The end of the spiral support plate away from the spiral rod is provided with a groove for locking the limiting ruler plate.

[0008] Optionally, a handle is fixedly connected to the end of the auger rod away from the scraper.

[0009] Optionally, a pair of pointer blocks that lock the limiting ruler plate are fixedly connected to one end of the spiral support plate near the slot.

[0010] Optionally, the top of the limiting ruler plate is fixedly connected to a limiting plate that holds the spiral support plate.

[0011] Optionally, the scraper plate has a spiral hole, and the end of the limiting ruler plate away from the limiting plate is movably inserted with a mounting screw that is spirally connected to the spiral hole.

[0012] Optionally, the rolling mechanism includes protruding rods fixedly connected to both ends of the U-shaped rod, with rotating rods movably inserted into the bottom ends of each protruding rod, and rollers fixedly connected to both ends of each rotating rod.

[0013] Optionally, a handle is fixedly connected to the end of the scraper away from the scraper pad, and a pair of U-shaped support blocks that movably pass through the end of the U-shaped rod are fixedly connected to the end of the scraper near the scraper pad.

[0014] In summary, this application includes at least one of the following beneficial technical effects:

[0015] This invention utilizes the cooperation of a scraper plate, an adjustment mechanism, a rolling mechanism, and a limiting ruler plate. When using the device, the scraper plate is pushed by the handle, and the rollers contact the mounting surface to ensure smooth movement. Rotating the handle drives the spiral rod to adjust the height of the U-shaped rod, which, together with the pointer block and the limiting ruler plate, precisely controls the height of the scraper pad to ensure consistent adhesive thickness. The U-shaped support block limits and enhances stability, avoiding fluctuations in force and angle caused by manual operation due to physical strength and habits, solving the problems of uneven pressure and thickness deviation, and achieving uniform scraping.

[0027] Example

[0028] like Figures 1 to 4 As shown, this utility model proposes a modified bitumen waterproof membrane coating device, including a coating plate 1, a coating pad 11 fixedly connected to the coating plate 1, a U-shaped rod 3 on the coating plate 1, rolling mechanisms at both ends of the U-shaped rod 3, and an adjustment mechanism connected to the middle, which can move up and down under the action of the adjustment mechanism to drive the rolling mechanisms to adjust the height. The rolling mechanisms at both ends of the U-shaped rod 3 are used to move the rolling mechanisms up and down. A limiting ruler 4 corresponding to the adjustment mechanism is installed on the coating plate 1. The limiting ruler 4 is installed on the coating plate 1, corresponds to the adjustment mechanism, and has a scale, which, together with the pointer block 33, precisely controls the distance between the coating pad 11 and the mounting surface.

[0029] Among them, such as Figure 1 and Figure 3 As shown, an adjustment mechanism is provided in the middle of the scraper plate 1 and the U-shaped rod 3. The adjustment mechanism includes a spiral support plate 31 fixedly sleeved in the middle of the U-shaped rod 3. The spiral support plate 31 is fixedly sleeved in the middle of the U-shaped rod 3 and spirally connected to the spiral rod 34. Under the drive of the spiral rod 34, the U-shaped rod 3 moves up and down. A spiral rod 34 spirally passes through the spiral support plate 31 and is rotatably connected in the middle of the scraper plate 1. The spiral rod 34 is rotatably connected in the middle of the scraper plate 1 and spirally passes through the spiral support plate 31. When rotating, it drives the spiral support plate 31 and the U-shaped rod 3 to move up and down. A slot 32 for locking the limiting ruler plate 4 is opened at the end of the spiral support plate 31 away from the spiral rod 34. The slot 32 is opened at the end of the spiral support plate 31 away from the spiral rod 34 to lock the limiting ruler plate 4 and assist in limiting.

[0030] Secondly, such as Figure 1 and Figure 3As shown, a handle 35 is fixedly connected to the end of the spiral rod 34 away from the scraper plate 1. The handle 35 is fixed to the end of the spiral rod 34 away from the scraper plate 1, making it convenient for the operator to rotate the spiral rod 34 to adjust the height. A pair of pointer blocks 33 that lock the limiting ruler plate 4 are fixedly connected to the end of the spiral support plate 31 near the slot 32. The pointer blocks 33 are located at the end of the spiral support plate 31 away from the spiral rod 34 and are used to lock the limiting ruler plate 4 for auxiliary limiting. A limiting plate 41 that locks the spiral support plate 31 is fixedly connected to the top of the limiting ruler plate 4. The limiting plate 41 is fixed to the top of the limiting ruler plate 4 and is used to lock the spiral support plate 31, thus limiting the spiral support plate 31.

[0031] In addition, such as Figure 1 and Figure 3 As shown, a spiral hole 12 is provided on the scraper plate 1. The spiral hole 12 is provided on the scraper plate 1 and is spirally connected to the mounting screw 42 for fixing the limiting ruler plate 4. The end of the limiting ruler plate 4 away from the limiting clamping plate 41 is movably inserted with the mounting screw 42, which is spirally connected to the spiral hole 12. The mounting screw 42 is movably inserted at the end of the limiting ruler plate 4 away from the limiting clamping plate 41 and is spirally connected to the spiral hole 12, thus fixing the limiting ruler plate 4 to the scraper plate 1.

[0032] It is worth noting that, such as Figure 1 , Figure 2 and Figure 3 As shown, the rolling mechanism includes protruding rods 301 fixedly connected to both ends of the U-shaped rod 3. Rotating rods 302 are movably inserted into the bottom ends of the protruding rods 301. Rollers 303 are fixedly connected to both ends of the rotating rods 302, allowing them to rotate with the rollers 303, facilitating movement of the device. Rollers 303 are fixedly connected to both ends of the rotating rods 302, contacting the waterproof membrane mounting surface to enable device movement and assist in adjusting the distance between the coating pad 11 and the mounting surface.

[0033] Furthermore, such as Figures 1 to 2 As shown, a handle 2 is fixedly connected to the end of the scraper plate 1 away from the scraper pad 11. The handle 2 is fixed to the end of the scraper plate 1 away from the scraper pad 11 for the operator to hold and push the device for scraping operations. A pair of U-shaped support blocks 5 are fixedly connected to the end of the scraper plate 1 near the scraper pad 11, which movably pass through the end of the U-shaped rod 3. The U-shaped support blocks 5 are fixed to the end of the scraper plate 1 near the scraper pad 11 and movably pass through the end of the U-shaped rod 3, which limits the end of the U-shaped rod 3 and ensures the stability of the scraping operation.

[0034] In this embodiment, when using the modified bitumen waterproof membrane scraping device, the hand handle 2 is used to push the scraping plate 1. At this time, the roller 303 rotates on the convex rod 301 through the rotating rod 302 to realize the movement of the device, and each roller 303 will contact the installation surface of the waterproof membrane, laying the foundation for the uniform scraping of the adhesive.

[0035] Next, turning the handle 35 will rotate the spiral rod 34. Since the spiral rod 34 and the spiral support plate 31 are spirally connected, the spiral support plate 31 will move the U-shaped rod 3 up and down, thereby adjusting the relative height between the roller 303 and the bottom of the coating pad 11. After adjustment, the roller 303 can make the coating pad 11 form a certain distance from the installation surface of the waterproof membrane. This distance is the uniform thickness of the adhesive applied to the coating pad 11.

[0036] Subsequently, by coordinating the pointer block 33 on the limit ruler plate 4 to point to the scale of the limit ruler plate 4, the distance between the scraping pad 11 and the mounting surface can be precisely controlled, thereby ensuring that the thickness of the adhesive scraped by the scraping pad 11 on the mounting surface is precisely controlled.

[0037] Finally, when the coating pad 11 contacts the mounting surface, the U-shaped support block 5 will limit the end of the U-shaped rod 3 to ensure the stability of the coating process.

[0038] The preferred embodiments of this utility model described above are merely illustrative of the present utility model. These preferred embodiments do not exhaustively describe all details, nor do they limit the utility model to any specific implementation. Clearly, many modifications and variations can be made based on the content of this specification. This specification selects and specifically describes these embodiments to better explain the principles and practical applications of this utility model, thereby enabling those skilled in the art to better understand and utilize it. This utility model is limited only by the claims and their full scope and equivalents.
