Description

Technical Field

[0001] The utility model relates to the technical field of masonry mortar construction tools, in particular to an adjustable masonry mortar spreading box. Background Art

[0002] In standard bricklaying construction techniques, the construction steps first include the construction workers manually spreading a layer of masonry mortar evenly on the prepared base or the existing brick wall, and then manually placing the bricks one by one to ensure precise alignment between the bricks.

[0003] However, in the process of manual mortar laying, not only will there be frequent problems of mortar overflow, dripping or excessive use, resulting in material waste and increasing the difficulty and labor intensity of subsequent cleaning work, but also manual mortar laying is difficult to ensure the uniformity of the interface between mortar and bricks, which may lead to uneven structure and reduced strength of the final wall and increase the risk of cracks. Secondly, this labor-intensive process is significantly less efficient than mechanized construction methods, especially in large-scale construction projects, which may significantly extend the construction period.

[0004] In order to improve the construction efficiency of mortar laying and reduce manual labor, the present application provides an adjustable masonry mortar spreading box.

[0005] The present application provides an adjustable masonry mortar paving box adopts the following technical solution:

[0006] An adjustable masonry mortar paving box comprises a first connecting part, a second connecting part and a movable scraper;

[0007] The first connecting portion includes a first side panel, a first back panel connected to one end of the first side panel, and a first extension panel connected to the bottom end of the first side panel; the second connecting portion includes a second side panel, a second back panel connected to one end of the second side panel, and a second extension panel connected to the bottom end of the second side panel; the first back panel is provided with a plurality of groups of back panel sliding grooves, the second back panel is provided with a plurality of back panel sliding rods, the back panel sliding rods are correspondingly penetrated and slide in the back panel sliding grooves, the second back panel is slidably connected to the first back panel by the sliding of the back panel sliding rods in the back panel sliding grooves, and the back panel sliding rods are also threadedly connected to a back panel fixing member for fixing; anti-overflow strips are respectively fixedly provided on the sides facing each other of the first extension panel and the second extension panel;

[0008] The movable scraper is provided with a plurality of scraper slide grooves extending horizontally, and a plurality of scraper slide rods are respectively provided at one end of the first side plate away from the first back plate and one end of the second side plate away from the second back plate. The scraper slide rods are correspondingly penetrated and slide in the scraper slide grooves, and the movable scraper is slidably connected with the first side plate and the second side plate through the sliding of the scraper slide rods in the scraper slide grooves, and the scraper slide rods are also threadedly connected with scraper fixings for fixing.

[0009] By adopting the above technical solution, the first connection part, the second connection part and the movable scraper are slidably connected to each other and form a frame structure surrounded by four sides. When mortar laying is carried out, it is only necessary to place the paving box on the top of the brick to be laid, and adjust the distance between the first connection part and the second connection part by sliding, so that the first extension plate and the second extension plate are correspondingly close to the two side edges of the brick, and the anti-overflow strip is stuck on both sides of the top of the brick. At this time, a discharge port is formed between the movable scraper and the top of the brick, and then mortar is added to the frame, and the paving box is pulled. The mortar flows out of the discharge port and is laid on the top of the brick. With the movable scraper, the mortar can be evenly laid and scraped flat at the same time. Not only is the mortar laying method simple and convenient, but the movable scraper can also evenly scrape flat during the laying process, which is conducive to improving the uniformity of mortar laying and improving construction efficiency. Secondly, since the distance between the first connection part and the second connection part can be adjusted by sliding, the overall frame width of the paving box can adapt to bricks of different thicknesses, which is conducive to improving the adaptability of the paving box.

[0011] By adopting the above technical solution, using the fixed position on the sliding slot, the distance between the first connecting part and the second connecting part can be pre-set to correspond to the thickness of the marked bricks. Therefore, when it is necessary to lay mortar on bricks of standard thickness, it is only necessary to slide the sliding card rod to the fixed position of the corresponding sliding slot to quickly adjust the distance between the first connecting part and the second connecting part to the corresponding width, thereby achieving rapid adaptation of the paving box and helping to improve construction efficiency.

[0012] Optionally, at least three groups of the backplane slide grooves are provided, and the number of the backplane slide rods provided corresponds one-to-one to the backplane slide grooves.

[0013] By adopting the above technical solution, when the first connection part and the second connection part slide relative to each other, they can be limited to each other by multiple groups of backplane sliding bars to keep the first connection part and the second connection part sliding along a straight line.

[0014] Optionally, the movable scraper is tilted, the vertical distance from the top of the movable scraper to the first back plate is smaller than the vertical distance from the bottom of the movable scraper to the first back plate, and the tilt angle of the movable scraper is 45°-60°.

[0015] By adopting the above technical scheme, due to the inclined setting of the movable scraper, the outlet of the paving box is larger than the inlet, which not only increases the single paving area of ​​the mortar, which is beneficial to improving the paving efficiency, but also the inclined movable scraper also gives certain guidance and downward pressure to the mortar in the paving box, which is beneficial to allow the mortar in the paving box to flow fully and be spread on the bricks.

[0016] Optionally, scraping teeth are provided at the bottom end of the movable scraper.

[0017] By adopting the above technical solution, when the paving box is paving mortar, the scraping teeth on the movable scraper can simultaneously scrape out uniform scratches, without the need for subsequent manual scraping, which is conducive to improving construction efficiency.

[0018] Optionally, the first side plate and the second side plate are slidably connected with grouting members on their sides facing away from each other. The grouting members extend vertically downward, and a horizontally extending grouting sheet is provided at the bottom end of the grouting members.

[0019] By adopting the above technical solution, construction workers can adjust the downward extension length of the grouting piece by sliding, so that the grouting piece can adapt to bricks of different heights, and the grouting piece can grout the mortar spread on the upper layer of bricks while spreading the mortar, which is conducive to improving construction efficiency.

[0020] Optionally, the grouting piece is provided with a grouting groove, and a plurality of grouting slide rods are respectively provided on the sides of the first side panel and the second side panel facing away from each other, and the plurality of grouting slide rods located on the same side are arranged in the vertical direction, and the grouting slide rods are correspondingly passed through and slide in the grouting grooves, and the grouting piece is slidably connected with the first side panel and the second side panel through the sliding of the grouting slide rods in the grouting grooves, and the grouting slide rods are also threadedly connected with a grouting fixing piece for fixing.

[0021] By adopting the above technical solution, the grouting slide rod is inserted and slid into the grouting slide groove of the grouting piece, and the grouting fixing piece is matched, so that the construction personnel can adjust the length of the grouting piece extending downward by sliding and fixing, so that the grouting piece can adapt to bricks of different heights, and the mortar on the upper layer of the bricks can be grouted while the mortar is being spread, which is conducive to improving construction efficiency. Secondly, since the several grouting slide rods located on the same side are arranged in the vertical direction, the several grouting slide rods can cooperate with each other and limit the grouting piece, so that the grouting piece is not easy to rotate during the sliding process, and the grouting piece can effectively keep sliding in the vertical direction.

[0022] Optionally, the width of the anti-overflow strip is 10-15 mm.

[0023] By adopting the above technical solution, when the paving box is moving to spread mortar, the anti-overflow strips on both sides can reserve a width of 10-15mm on both sides of the top of the brick, which is helpful to prevent the mortar from overflowing the edge of the brick and reduce material waste.

[0024] In summary, the technical solution of this application includes at least one of the following beneficial effects:

The first side plate 11 is arranged opposite to the second side plate 21, the first back plate 12 is slidably connected to the second back plate 22, and the two sides of the movable scraper 3 are respectively slidably connected to the end of the first side plate 11 away from the first back plate 12 and the end of the second side plate 21 away from the second back plate 22, so that the first connecting part 1, the second connecting part 2 and the movable scraper 3 are slidably connected to each other to form a frame structure surrounded on all four sides.

[0039] Reference Figure 2 and Figure 3 The first back plate 12 is provided with a plurality of back plate slide grooves 121, and the second back plate 22 is provided with a plurality of back plate slide bars 221 corresponding to the back plate slide grooves 121. The back plate slide bars 221 are inserted into the corresponding back plate slide grooves 121 and can slide along the back plate slide grooves 121, so that the second back plate 22 slides in the back plate slide grooves 121 through the back plate slide bars 221 to achieve a sliding connection with the first back plate 12, that is, a sliding connection between the first connection part 1 and the second connection part 2 is achieved. In this embodiment, three back plate slide grooves 121 and three back plate slide bars 221 are respectively provided, and more groups of back plate slide grooves 121 and back plate slide bars 221 may be provided in other embodiments. Specifically, the three backplane grooves 121 are evenly arranged along the vertical direction of the first backplane 12, and the three backplane slide bars 221 are respectively inserted into the three backplane grooves 121, so that when the first connection part 1 and the second connection part 2 slide relative to each other, the three backplane slide bars 221 can limit each other and keep the first connection part 1 and the second connection part 2 sliding in a straight line.

[0040] Furthermore, the back panel slide rod 221 is threadedly connected with a back panel fixing part 222 for fixing the first back panel 12 and the second back panel 22. Specifically, in the present embodiment, the back panel slide rod 221 is a screw rod, and the back panel fixing part 222 is a butterfly nut, so that when the butterfly nut is tightened, the first back panel 12 and the second back panel 22 are pressed against each other. At this time, the first back panel 12 and the second back panel 22 cannot slide relative to each other, thereby achieving the fixation of the first connection part 1 and the second connection part 2.

[0041] Reference Figure 3The back plate slide groove 121 includes a main slide groove 1211 and a plurality of groups of slide slots 1212, wherein the main slide groove 1211 extends in the horizontal direction, and the plurality of groups of slide slots 1212 are evenly arranged and distributed along the extension direction of the main slide groove 1211, and are interconnected with the main slide groove 1211. Further, the slide slot 1212 is in a "7" shape or a "1" shape, wherein the end of the "7"-shaped slide slot 1212 away from the main slide groove 1211 is provided with two groups of fixed positions 1213, and the end of the "1"-shaped slide slot 1212 away from the main slide groove 1211 is provided with a group of fixed positions 1213, when the back plate slide bar 221 slides to the fixed positions 1213 of the slide slot 1212, the distance between the first connection part 1 and the second connection part 2 corresponds to the thickness of a standard brick wall block. Specifically, in this embodiment, there are four groups of "7"-shaped sliding slots 1212 and one group of "1"-shaped sliding slots 1212, so there are nine groups of fixed positions 1213, and the fixed positions 1213 correspond to brick wall blocks with thicknesses of 100mm, 120mm, 125mm, 150mm, 180mm, 200mm, 240mm, 250mm and 300mm, respectively. Therefore, when it is necessary to lay mortar on bricks with the above standard thickness, the distance between the first connection part 1 and the second connection part 2 can be quickly adjusted by sliding the sliding card rod to the corresponding fixed position 1213, so as to achieve rapid adaptation of the paving box, which is conducive to improving construction efficiency.

[0042] Reference Figure 1 , Figure 4 and Figure 5 The movable scraper 3 is provided with a plurality of scraper slide grooves 31, which extend in the horizontal direction and are evenly distributed along the direction of the movable scraper 3. A plurality of scraper slide bars 4 are respectively provided at one end of the first side plate 11 away from the first back plate 12 and at one end of the second side plate 21 away from the second back plate 22. The plurality of scraper slide bars 4 correspond to the plurality of scraper slide grooves 31 one by one. The scraper slide bars 4 are inserted and slide in the scraper slide grooves 31. The movable scraper 3 is slidably connected with the first side plate 11 and the second side plate 21 by the sliding of the scraper slide bars 4 in the scraper slide grooves 31, that is, the sliding connection between the movable scraper 3 and the first connecting portion 1 and the second connecting portion 2 is realized, so that the movable scraper 3 does not cause any interference effect on the distance adjustment between the first connecting portion 1 and the second connecting portion 2. Specifically, in the present embodiment, the movable scraper 3 is provided with two scraper grooves 31, the two scraper grooves 31 are parallel to each other, and the first side plate 11 and the second side plate 21 are respectively provided with two scraper slide rods 4 passing through the two scraper grooves 31, so that when the first connection part 1 and the second connection part 2 slide relative to each other, the two scraper slide rods 4 on either side can limit each other and keep the first connection part 1 and the second connection part 2 sliding in a straight line close to one end of the movable scraper 3.

[0043] Furthermore, the scraper slide bar 4 is threadedly connected with a scraper fixing member 41, and the scraper fixing member 41 is used to fix the movable scraper 3 and the first side plate 11 and the second side plate 21. Specifically, in the present embodiment, the scraper slide bar 4 is a screw rod, and the scraper fixing member 41 is a butterfly nut, so that when the butterfly nut is tightened, the two sides of the movable scraper 3 are respectively pressed against the first side plate 11 and the second side plate 21. At this time, the movable scraper 3 and the first side plate 11 and the second side plate 21 cannot slide relative to each other, thereby realizing the fixation of the movable scraper 3 and the first connecting part 1 and the second connecting part 2.

[0044] Reference Figure 1 and Figure 4 , the movable scraper 3 is inclined. Specifically, the vertical distance from the top of the movable scraper 3 to the first back plate 12 is smaller than the vertical distance from the bottom of the movable scraper 3 to the first back plate 12, and the inclination angle of the movable scraper 3 is 45°-60°. In this embodiment, the inclination angle of the movable scraper 3 is 60°. This can effectively increase the discharge port of the paving box and increase the paving area of ​​the mortar, which is beneficial to improving construction efficiency. In addition, the bottom end of the movable scraper 3 is also provided with scraping teeth 32, so that when the paving box is paving the mortar, the scraping teeth 32 on the movable scraper 3 can scrape out uniform scratches at the same time, without the need for subsequent manual scraping, which is beneficial to improving construction efficiency.

[0045] Reference Figure 4 and Figure 6 The first side panel 11 and the second side panel 21 are both connected with a grouting member 5 in a sliding manner in the vertical direction on the side facing away from each other. The bottom end of the grouting member 5 is provided with a horizontally extending grouting piece 51, and the grouting piece 51 is parallel to the first side panel 11 or the second side panel 21, wherein the grouting piece 51 is used to grout the mortar paved on the previous layer. Specifically, the grouting member 5 is provided with a grouting slot 52, and the first side panel 11 and the second side panel 21 are respectively provided with a plurality of grouting slide bars 6 on the side facing away from each other. The grouting slide bars 6 are correspondingly inserted and slide in the grouting slot 52. The grouting member 5 is slidably connected with the first side panel 11 and the second side panel 21 by the sliding of the grouting slide bars 6 in the grouting slot 52, so that the construction personnel can adjust the downward extension length of the grouting member 5 by sliding, so that the grouting piece 51 can adapt to bricks of different heights and grout the mortar paved on the previous layer.

[0046] Furthermore, the grouting slide rod 6 is threadedly connected with a grouting fixing member 61 for fixing the grouting member 5. Specifically, in the present embodiment, the grouting slide rod 6 is a screw rod, and the grouting fixing member 61 is a butterfly nut, so that when the butterfly nut is tightened, the grouting member 5 is pressed against the first side plate 11 or the second side plate 21, and at this time, relative sliding cannot occur between the grouting member 5 and the first back plate 12 or the second back plate 22, thereby achieving fixation of the grouting member 5.

[0047] Reference Figure 4 , the first extension plate 13 and the second extension plate 23 are respectively fixed with anti-overflow strips 7 on the side facing each other, wherein the anti-overflow strips 7 are used to assist in supporting the entire paving box and prevent the mortar from overflowing the edge of the brick. Specifically, the top of the anti-overflow strip 7 on the first extension plate 13 is flush with the top of the first extension plate 13, and the top of the anti-overflow strip 7 on the second extension plate 23 is flush with the top of the second extension plate 23, so that when the paving box is placed on the top of the brick, the anti-overflow strip 7 is stuck on both sides of the top of the brick and supports the entire paving box. At this time, a discharge port is formed between the movable scraper 3 and the brick, so that when the paving box is pulled, the mortar can flow out of the movable scraper 3 evenly. Furthermore, the width of the anti-overflow strip 7 is 10-15mm. When the paving box is moving to spread the mortar, the anti-overflow strips 7 on both sides can reserve a width of 10-15mm on both sides of the top of the brick, which is conducive to preventing the mortar from overflowing the edge of the brick and reducing material waste. Specifically, in this embodiment, the width of the anti-overflow strip 7 is 10 mm.

[0048] The implementation principle of an adjustable masonry mortar paving box in the embodiment of the present application is:

[0049] When mortar laying is required, the distance between the first connection part 1 and the second connection part 2 is adjusted according to the thickness of the required paving bricks. Specifically, the distance can be easily adjusted by sliding the back plate slide bar 221 in the back plate slide groove 121. If the thickness of the required paving bricks is the standard thickness, the adjustment can be completed by directly sliding the back plate slide bar 221 to the fixed position 1213 corresponding to the sliding groove 1212.

[0050] After the adjustment is completed, the paving box can be placed directly on the top of the brick. At this time, the first extension plate 13 and the second extension plate 23 are correspondingly close to the two side edges of the brick, the anti-overflow strip 7 is stuck on both sides of the top of the brick, and a discharge port is formed between the movable scraper 3 and the top of the brick. Then, the length of the grouting piece 5 extending downward is adjusted according to the height of the brick, so that the grouting piece 51 can be aligned with the position of the mortar layer on the brick.

[0051] Finally, add mortar to the paving box, pull the paving box, and the mortar will flow out from the discharge port and be laid on the top of the brick. The movable scraper 3 will fully scrape the mortar and leave scratches, and the mortar laying construction is completed. While laying, the grouting sheet 51 can grout the mortar of the upper layer, and the anti-overflow strip 7 can reserve a certain width on both sides of the top of the brick and effectively prevent the mortar from overflowing the edge of the brick, reducing material waste.

[0052] This specific implementation manner is merely an explanation of the present application and is not a limitation of the present application. After reading this specification, those skilled in the art may make non-creative modifications to the specific implementation manner as needed, but such modifications are protected by the patent law as long as they are within the scope of the claims of the present application.
