Description

Technical Field

[0001] This utility model belongs to the field of building construction tools technology, specifically to a slab paving scraper. Background Technology

[0002] With changing aesthetic standards, using marble and other stone materials as floor tiles has become a trend. In the process of laying sintered stone slabs, leveling mortar is first laid flat on the base surface, and then the sintered stone slabs are laid one by one on the leveling mortar layer using sintered stone slab adhesive, and finally tapped and compacted with a wooden mallet.

[0003] Before laying the slab, a squeegee is needed to spread the adhesive evenly to ensure that the adhesive slurry is of uniform height and that the slab is flat. The existing squeegee requires the construction worker to hold it and squat down to scrape the material, which is inconvenient to operate and can easily cause fatigue if squatting down for a long time.

[0026] The embodiments of this application are described in detail below. Examples of these embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain this application, and should not be construed as limiting this application.

[0027] In this application, unless otherwise expressly specified and limited, the terms "installation," "connection," "linking," and "fixing," etc., should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral part; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components. Those skilled in the art can understand the specific meaning of the above terms in this application according to the specific circumstances.

[0028] In this application, unless otherwise expressly specified and limited, "above" or "below" the second feature can mean that the first feature is in direct contact with the second feature, or that the first feature is in indirect contact with the second feature through an intermediate medium. Furthermore, "above," "on top of," and "over" the second feature can mean that the first feature is directly above or diagonally above the second feature, or simply that the first feature is at a higher horizontal level than the second feature. "Below," "below," and "under" the second feature can mean that the first feature is directly below or diagonally below the second feature, or simply that the first feature is at a lower horizontal level than the second feature.

[0029] Please refer to Figure 1-8 The image shows a slab paving scraper provided by this utility model. Example 1: Includes a scraper 1, which is mounted on a mounting base 2. One end of the scraper 1 has scraping teeth 11. A positioning guide block 3 is fixed at the bottom of the mounting base 2, and a handle rod 4 is connected to the rear. The positioning guide block 3 has an inclined mounting surface 31. The scraper 1 and the mounting base 2 are mounted on the mounting surface 31 and are inclined with the mounting surface 31. One end of the scraper 1 with scraping teeth 11 extends to the front side of the positioning guide block 3.

[0030] Mounting base 2 includes mounting square tube 21, and scraper 1 is bolted to the bottom surface of mounting square tube 21.

[0031] There are multiple positioning guide blocks 3, which are flat plates arranged in parallel to each other.

[0032] The bottom rear side of the positioning guide block 3 has a chamfer.

[0033] The upper rear side of the positioning guide block 3 has a hook block 32, which contacts and limits the mounting base 2.

[0034] Scraper 1 is made of elastic and wear-resistant material.

[0035] Among them, the positioning guide block 3 is triangular thin plate with a narrow bottom surface, which allows it to cut through the adhesive slurry when sliding on it, so that the bottom surface contacts the leveling mortar layer.

[0036] When in use, the construction worker holds the handle rod 4 and drags the scraper to move it, keeping the bottom of the positioning guide block 3 in contact with the leveling mortar layer, that is, keeping the angle of the handle rod 4 unchanged. At this time, the height of the scraper 1 and the scraper teeth 11 remains unchanged, and they move in parallel to scrape the mortar level.

[0037] In Embodiment 2, which is a further improvement on Embodiment 1, a support rod 5 is installed in the middle of the handle rod 4. The bottom surface of the support rod 5 is on the same plane as the bottom surface of the positioning guide block 3, and the support rod 5 is flat and long. That is, when the support rod 5 is supported on the leveling mortar layer, the angle of the handle rod 4 is the normal scraping angle, so that the construction personnel can better keep the angle of the handle rod 4 unchanged, and prevent the scraper from falling over when the scraping is interrupted and rested.

[0038] In Embodiment 3, which is a further improvement on Embodiment 2, the support rod 5 is shortened and a roller 51 is installed at the bottom of the support rod 5. Specifically, the roller 51 is in the shape of a thin sheet and is connected to the support rod 5 by bolts passing through the wheel center. The bottom contact point of the roller 51 is on the same plane as the bottom surface of the positioning guide block 3. Compared with Embodiment 2, the setting of the roller 51 makes the scraper more effortless and smooth when dragging, and it is less likely to cause vibration due to friction and impact caused by small protrusions on the leveling mortar layer.

[0039] In the improved embodiment four based on embodiment one, the handle rod 4 is hinged to the mounting base 2. At this time, even if the construction personnel raise or lower the handle rod 4, it will not affect the angle of the positioning guide block 3, the mounting base 2 and the scraper 1, which facilitates the movement of the construction personnel. However, the positioning guide block 3 lacks the force to keep its bottom in close contact with the leveling mortar layer. Therefore, a counterweight is also placed inside the mounting square tube 21. The counterweight can be made of on-site bricks, cement blocks, steel blocks, etc. The weight of the counterweight keeps the bottom of the positioning guide block 3 sliding along the leveling mortar layer.

[0040] In Embodiment 5, which is an improvement on Embodiments 3 and 4, the schemes of Embodiments 3 and 4 are combined, and the support rod 5 is set as a telescopic rod. Specifically, the lower half of the support rod 5 is changed to a hollow strip shape, and the upper half fits into the lower half. Uniform pin holes are opened at their intersection, and the pin is fixed by passing through the pin holes. At this time, the construction personnel can change the position of the pin hole through which the pin passes and adjust the length of the support rod 5 so that the handle rod 4 is kept at a comfortable angle and height when it is dragged.

[0041] Although embodiments of this application have been shown and described above, it is understood that the above embodiments are exemplary and should not be construed as limiting this application. Those skilled in the art can make changes, modifications, substitutions and variations to the above embodiments within the scope of this application.
