Description

Technical Field

[0001] This utility model belongs to the field of waterproof asphalt coating technology, specifically relating to an asphalt coating device for waterproof membrane rolls. Background Technology

[0002] Asphalt coating of waterproof membrane is a common waterproofing construction method. The substrate surface should be firm, flat, dry, clean, and free of dust and oil. Corners should be beveled at 50mm x 50mm or rounded at 50mm radius. Apply a primer evenly to the qualified substrate. The primer should be thoroughly stirred before application. The coating should be applied evenly, without any gaps or accumulation. Heat the non-curing rubber asphalt waterproof coating in a heating tank until it reaches a liquid state. The heated asphalt needs to be treated with a scraper. The heating temperature for manual scraping should be ≥120℃. Apply the heated non-curing rubber asphalt waterproof coating evenly to the substrate with a scraper, with a thickness of about 1mm.

[0003] Currently, commonly used scraping devices include horizontally set scrapers and handles fixed to the scrapers. Since the size of the horizontally set scrapers is constant, the liquid asphalt will flow to both sides of the scraper during scraping, which requires multiple scrapings to make the asphalt smooth, resulting in low scraping efficiency. Utility Model Content

An installation tube is fixed to the scraper, and a handle is inserted into the installation tube. The metal elastic piece in the handle pushes the positioning rod into the positioning hole on the installation tube, thus fixing the handle to the scraper. Squeezing the positioning rod causes the metal elastic piece to move downwards. After the positioning rod moves out of the positioning hole, the installation tube separates from the handle, facilitating the installation and disassembly of the scraper and improving the ease of scraper replacement.

[0009] Preferably, one end of the handle is fixedly fitted with an anti-slip sleeve, and the other end of the handle is fitted into the mounting tube. The positioning mechanism includes a metal elastic piece with a V-shaped structure embedded in the handle and a positioning rod fixed to the top of the metal elastic piece.

[0012] Furthermore, a groove is provided at the center of the side wall of the connecting block, and elastic parts are provided at both ends of the connecting block. The side wall of the elastic part is fixed with a card block embedded in the card slot.

[0013] Furthermore, the connecting block is fixed to the side wall of the extension plate, the extension plate has an arc-shaped part, and a leak-proof plate is installed obliquely along the plate through the arc-shaped part.

[0014] Furthermore, the extension plate is horizontally arranged in an L-shape, and the sidewalls of the extension plate are fixed to the connecting block.

[0015] Furthermore, the connecting block is set separately, and the connecting block fits into the connecting groove at the same horizontal position as the side wall of the scraper.

[0016] (3) Beneficial effects

[0017] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0018] This utility model has extension plates installed at both ends of the scraper. The extension plates increase the scraping area of ​​the scraper. At the same time, the arc-shaped part and the anti-leak plate on the extension plate can collect liquid asphalt, avoiding the asphalt from flowing on both sides of the scraper during the scraping process, thus improving the scraping efficiency of asphalt.

[0019] By fixing an installation tube to the scraper, inserting the handle into the installation tube, and pushing the positioning rod into the positioning hole on the installation tube with the metal elastic piece in the handle, the handle and scraper are kept fixed.

[0027] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0028] This specific embodiment is a waterproof membrane asphalt coating device, the structural diagram of which is shown below. Figure 1 and Figure 2As shown, the waterproof membrane asphalt coating device includes a scraper 1 and a handle 4 detachably fixed to the scraper 1. Both ends of the scraper 1 are provided with connecting grooves 6. Connecting blocks 13 are inserted into the connecting grooves 6 and extension plates 3 fixed to the scraper 1 are installed through the connecting blocks 13. An installation tube 7 is fixed at the center of the scraper 1. A positioning hole 2 is provided at the top of the installation tube 7. A positioning mechanism that engages with the positioning hole 2 is provided in the handle 4.

[0029] One end of the handle 4 is fixedly fitted with an anti-slip sleeve 5, and the other end of the handle 4 is inserted into the mounting tube 7. The positioning mechanism includes a metal elastic piece 9 embedded in the handle 4 in a V-shape and a positioning rod 8 fixed to the top of the metal elastic piece 9. The positioning rod 8 is slidably inserted into the outer wall of the handle 4, and the top of the positioning rod 8 passes through the handle 4 and is inserted into the positioning hole 2. The handle 4 is inserted into the mounting tube 7. The metal elastic piece 9 in the handle 4 pushes the positioning rod 8 into the positioning hole 2 on the mounting tube 7, thereby keeping the handle 4 and the scraper 1 fixed. Squeezing the positioning rod 8 causes it to squeeze the metal elastic piece 9 to move downward. After the positioning rod 8 moves out of the positioning hole 2, the mounting tube 7 is separated from the handle 4, which facilitates the installation and removal of the scraper 1.

[0030] like Figures 3 to 5 As shown, both ends of the scraper 1 are provided with slots 10 that communicate with the connecting groove 6. A connecting block 13 is inserted into the connecting groove 6. A groove 16 is provided at the center of the side wall of the connecting block 13. Both ends of the connecting block 13 are provided with elastic parts 15. The side wall of the elastic part 15 is fixed with a locking block 14 embedded in the slot 10. When the connecting block 13 is installed, it is inserted into the connecting groove 6. The inclined part on the locking block 14 abuts against the inner wall of the connecting groove 6, causing the elastic part 15 to retract into the groove 16. After the connecting block 13 is fully inserted into the connecting groove 6, the elastic part 15 drives the locking block 14 to be inserted into the slot 10 and fixed.

[0031] In the first embodiment, the connecting block 13 is fixed to the side wall of the extension plate 3. An arc-shaped part 12 is fixed on the extension plate 3, and a leak-proof plate 11 is installed obliquely along the plate through the arc-shaped part 12. At the same time, the arc-shaped part 12 and the leak-proof plate 11 on the extension plate 3 can collect liquid asphalt, thus preventing the asphalt from flowing on both sides of the scraper 1 during the scraping process.

[0032] In the second embodiment, the extension plate 3 is horizontally arranged in an L-shape, and the side wall of the extension plate 3 is fixed to the connecting block 13. The extension plate 3 increases the scraping area of ​​the scraper 1, which greatly increases the scraping area of ​​the scraper 1.

[0033] In the third embodiment, the connecting block 13 is set separately and is inserted into the connecting groove 6 at the same horizontal position as the side wall of the scraper 1. The scraper 1 is used alone for scraping and coating, which is suitable for narrow spaces. The connecting block 13 is inserted into the connecting groove 6 on the scraper 1 to block it, thereby avoiding the situation where asphalt enters the connecting groove 6 and the slot 10 and causes blockage when the scraper 1 is used alone.

[0034] Working principle: When using the device of this technical solution, the handle 4 is inserted into the installation tube 7. The metal elastic piece 9 in the handle 4 pushes the positioning rod 8 into the positioning hole 2 on the installation tube 7, so that the handle 4 and the scraper 1 are fixed. The connecting block 13 is inserted into the connecting groove 6 during installation. The inclined part on the locking block 14 abuts against the inner wall of the connecting groove 6, so that the elastic part 15 retracts into the groove 16 until the connecting block 13 is fully inserted into the connecting groove 6. Then, the elastic part 15 drives the locking block 14 to be inserted into the locking groove 10 and fixed. The extension plate 3 increases the scraping area of ​​the scraper 1. At the same time, the arc-shaped part 12 and the anti-leakage plate 11 on the extension plate 3 can collect liquid asphalt, avoiding the situation that the asphalt flows on both sides of the scraper 1 during the scraping process, thus improving the scraping efficiency of asphalt.

[0035] All technical features in this embodiment can be freely combined according to actual needs.

[0036] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model.
