Description

Technical Field

[0001] This utility model relates to a masonry leveling device, and more particularly to a leak-proof device for leveling mortar in aerated block masonry. Background Technology

[0002] The application of aerated concrete block masonry technology is increasing day by day. On construction sites where manual smearing is used, the traditional smearing method consumes a lot of time and is inefficient. The bonding surface is not sufficiently covered and mortar is left behind, resulting in a lot of waste and increasing construction costs.

[0003] To improve the efficiency of manual masonry construction, optimize the operation steps, and enhance the quality of masonry work, this utility model designs a mortar leveling and leak-proof device. Utility Model Content

[0004] To solve the above-mentioned technical problems, this utility model provides a masonry mortar leveling and leak-proof device that is low in cost, simple to operate, highly efficient in construction, has good leak-proof effect, and high uniformity.

[0005] This utility model discloses a mortar leveling and leak-proof device, comprising a material holding part and a leveling part. The material holding part includes a first side wall, a second side wall, a third side wall, and a base plate. The first side wall, the second side wall, and the third side wall are all vertically arranged on the upper surface of the base plate and form a U-shaped structure. The third side wall is connected between the first side wall and the second side wall. The ends of the first side wall and the second side wall away from the third side wall are both inclined. The upper end of the inclined surface is closer to the third side wall than the lower end. The leveling part is slidably arranged on the inclined surfaces of the first side wall and the second side wall.

[0006] This utility model relates to a mortar leveling and leak-proof device, wherein the leveling part is a leveling knife, and the lower end of the leveling knife is provided with discharge teeth.

[0007] This utility model discloses a mortar leveling and leak-proof device, wherein a guide device is provided on the inclined surfaces of the first and second side walls, and a sliding device corresponding to the guide device is provided on one surface of the leveling trowel. The leveling trowel is slidably connected to the guide device through the sliding device.

[0008] This utility model discloses a mortar smoothing and leak-proof device, wherein the guiding device is a T-shaped groove, the sliding device is a T-shaped slider, and the smoothing knife is slidably disposed in the T-shaped groove of the first side wall and the second side wall through the T-shaped slider.

[0009] This utility model discloses a mortar leveling and leak-proof device, wherein the guiding device is a Z-shaped groove, the sliding device is an L-shaped slider, and the leveling knife is slidably disposed in the Z-shaped groove of the first side wall and the second side wall via the L-shaped slider.

[0010] This utility model relates to a mortar leveling and leak-proof device, wherein the leveling knife is provided with a handle, and the handle is located on another surface of the leveling knife.

[0011] This utility model relates to a mortar leveling and leak-proof device, wherein the slope of the first sidewall and the second sidewall is 45 degrees.

[0012] The difference between this utility model and the prior art is that this utility model uses a material holding part with a groove to hold the masonry mortar, and then uses a trowel blade that slides to connect with it to discharge and smooth the mortar. The trowel blade is provided with discharge teeth for discharging the mortar. By sliding the trowel blade up and down, the masonry mortar in the material holding part is evenly spread onto the aerated block through the discharge teeth, thus completing the material distribution.

[0013] This utility model provides a mortar leveling and leak-proof device that includes at least the following beneficial effects:

[0014] During the masonry process, not only is the operation simple, but the material is also evenly distributed (i.e., the thickness of the masonry mortar is uniform), which can also effectively prevent the masonry mortar from flowing out, save construction costs, and improve construction efficiency.

[0015] The present invention will be further described below with reference to the accompanying drawings. Attached Figure Description

Detailed Implementation

[0024] like Figure 1 , 3 As shown, this utility model discloses a mortar leveling and leak-proof device, comprising a material holding part 01 and a leveling part 02.

[0025] The material holding part 01 includes a first side wall 11, a second side wall 13, a third side wall 14 and a base plate 15. The first side wall 11, the second side wall 13 and the third side wall 14 are all vertically arranged on the upper surface of the base plate 15 and form a U-shaped structure. The third side wall 14 is connected between the first side wall 11 and the second side wall 13. The ends of the first side wall 11 and the second side wall 13 away from the third side wall 14 are both set with inclined surfaces 123. The upper end of the inclined surface 123 is arranged closer to the third side wall 14 than the lower end. The smoothing part 02 is slidably arranged on the inclined surface 123 of the first side wall 11 and the second side wall 13.

[0026] During construction, the smoothing part 02 is installed on the material holding part 01 and slid down to the bottom of the material holding part 01, i.e., the lower end of the first side wall 11 and the second side wall 13. The material holding part 01 and the smoothing part 02 form a U-shaped material holding structure with an opening on the right side. The masonry mortar is poured into the material holding part 01 from the open top. Then, the smoothing and leak-proof device is placed on the wall being built (i.e., on the aerated concrete block). The smoothing part 02 is slid upward to leave a certain gap between the smoothing part 02 and the bottom of the material holding part 01. The size of the gap is not specifically limited here and can be set according to the actual situation. The thickness of the masonry mortar laid on the wall is controlled by this gap. At this time, the masonry mortar in the material holding part 01 flows out from the gap. The smoothing and leak-proof device is gradually pulled backward to spread the masonry mortar evenly on the wall surface, completing the material placement. Then, the aerated concrete block is built on the masonry mortar, and the cycle is repeated to complete the construction of the wall.

[0027] During the masonry process, not only is the operation simple, but the material is also evenly distributed (i.e., the thickness of the masonry mortar is uniform), which can also effectively prevent the masonry mortar from flowing out, save construction costs, and improve construction efficiency.

[0028] It should be noted that the smoothing and leak-proof device of this utility model is not only applicable to the construction of aerated concrete block walls, but also to other block walls, such as brick walls and stone walls.

[0029] The materials for the first sidewall 11, the second sidewall 13, the third sidewall 14, and the base plate 15 are not particularly limited here; wear-resistant and corrosion-resistant materials such as engineering plastics, stainless steel, and aluminum alloys can be used. All three sidewalls are firmly fixed to the upper surface of the base plate 15 and perpendicular to it. They can be connected by welding, bolting, riveting, adhesive bonding, or a combination of these methods. The first sidewall 11 and the second sidewall 13 are fixed to both ends of the base plate 15, the third sidewall 14 is fixed to the left end of the base plate 15, and the smoothing part 02 is located at the right end of the base plate 15, thus forming a seamless, leak-proof material-holding structure to ensure that the masonry mortar does not overflow.

[0030] The first sidewall 11 and the second sidewall 13 adopt a right-angled trapezoidal structure. The inclined surface 123 of the right-angled trapezoid with a certain angle cooperates with the smoothing part 02 to form an inclined discharge port. The inclined surface 123 is inclined downward from left to right (that is, the upper end of the inclined surface 123 is closer to the third sidewall 14 than the lower end). On the one hand, it is convenient to contact the wall (such as a right-angled corner), and on the other hand, it can prevent the masonry mortar from splashing and discharge the material evenly.

[0031] like Figure 1 As shown, the smoothing section 02 uses a smoothing blade 21, and the lower end of the smoothing blade 21 is provided with discharge teeth 22.

[0032] The smoothing section 02 uses a rectangular smoothing knife 21, but other shapes are also possible. The rectangular smoothing knife 21 is more convenient to cooperate with the material holding section 01 (i.e., the first and second side walls and the rectangular base plate 15 in the shape of a right-angled trapezoid) to form a material discharge gap. The lower end of the smoothing knife 21 has multiple discharge teeth 22 evenly arranged along its length. During construction, the smoothing knife 21 is slid upward, and the masonry mortar flows out from the discharge teeth 22 and is evenly distributed on the wall. Moreover, multiple stripes are formed on the distributed masonry mortar, reducing unnecessary mortar coverage area. This not only saves materials, but also enhances the bonding and friction between aerated blocks, thereby improving the quality of the masonry wall.

[0033] like Figure 1 As shown, guide devices 12 are provided on the inclined surfaces 123 of the first sidewall 11 and the second sidewall 13. A sliding device 24 corresponding to the guide device 12 is provided on one surface of the smoothing knife 21. The smoothing knife 21 is slidably connected to the guide device 12 through the sliding device 24.

[0034] The guide device 12 is disposed on the inclined surface 123 of the first side wall 11 and the second side wall 13, such as Figure 3 As shown, a sliding device 24 is provided at both the upper and lower ends of the left side surface of the smoothing knife 21. The smoothing knife 21 is installed in the guide device 12 of the first side wall 11 and the second side wall 13 through the two sliding devices 24, so as to realize the sliding connection between the two.

[0035] A sliding device 24 is provided at both ends of the smoothing part 02. A guide device 12 is also provided on both sides of the material holding part 01 (i.e. on the inclined surfaces of the first side wall 11 and the second side wall 13). The guide device 12 corresponds to the sliding device 24. The smoothing part 02 is installed on the guide device 12 of the first side wall 11 and the second side wall 13 through the two sliding devices 24, and can be removed at any time for easy maintenance or replacement of parts.

[0036] During construction, when loading material into the material holding section 01, the trowel 21 is slid to the lower end of the material holding section 01, ensuring a seamless fit between the trowel 21 and the bottom plate 15, first side wall 11, and second side wall 13 of the material holding section 01. This tight fit without gaps ensures that the mortar will not leak from the connection between the trowel 21 and the walls during the loading process. When spreading the mortar, the trowel 21 is slid upwards, creating a gap between the discharge teeth 22 on the trowel 21 and the material holding section 01, allowing the mortar to flow out and completing the spreading process.

[0037] like Figure 1 , 2 As shown, the guide device 12 is a T-shaped groove 121, the sliding device 24 is a T-shaped slider 241, and the smoothing knife 21 is slidably disposed in the T-shaped groove 121 of the first side wall 11 and the second side wall 13 through the T-shaped slider 241.

[0038] In one embodiment, the guide device 12 is a T-shaped groove 121 provided on the inclined surface 123 of the first sidewall 11 and the second sidewall 13, such as Figure 3 As shown, the sliding device 24 is a T-shaped slider 241 that can be adapted to the T-shaped groove 121, allowing the trowel 21 to slide on the material holding part 01. The fit between the trowel 21 and the material holding part 01 is relatively tight, ensuring that the masonry mortar will not leak. During installation or disassembly, the T-shaped slider 241 on the trowel 21 is inserted into or removed from the upper end of the T-shaped groove 121. The operation is simple and facilitates maintenance and component replacement.

[0039] like Figure 4 , 5 As shown, the guide device 12 is a Z-shaped groove 122, the sliding device 24 is an L-shaped slider 242, and the smoothing knife 21 is slidably disposed in the Z-shaped groove 122 of the first side wall 11 and the second side wall 13 through the L-shaped slider 242.

[0040] In another embodiment, the guide device 12 is configured as a Z-shaped groove 122, such as Figure 6As shown, the sliding device 24 is configured with an L-shaped slider 242 that is compatible with it, which facilitates smooth sliding of both. Compared with the T-shaped groove 121, the Z-shaped groove 122 has better stability and more precise positioning (such as the cooperation between the L-shaped slider and the Z-shaped groove, which can better resist shaking caused by external forces). When the smoothing knife 21 slides on the material holding part 01, the smoothing knife 21 can be locked at the corner of the Z-shaped groove 122 by the L-shaped slider 242 to limit its position and ensure that the smoothing knife 21 can be fixed in a certain position on the material holding part 01 and will not slip off.

[0041] When laying the mortar, slide the trowel 21 upwards and lock it at a corner of the Z-shaped groove 122 of the material holding section 01. The masonry mortar in the material holding section 01 flows out from the discharge teeth 22 of the trowel 21, completing the laying process. This makes laying the mortar more convenient and improves construction efficiency.

[0042] like Figure 3 , 6 As shown, a handle 23 is provided on the smoothing knife 21, and the handle 23 is provided on another surface of the smoothing knife 21.

[0043] A handle 23 is bolted or welded to the right side of the trowel 21. The material and shape of the handle 23 are not specifically limited. Given the wide variety of materials available on the market and varying budgets, the material and shape of the handle 23 are not strictly limited. Common and economical materials such as plastic and wood, or sturdy but more expensive materials such as metal, can be flexibly selected based on cost budget to avoid resource waste. The handle 23 serves two purposes: firstly, it facilitates the operation of the trowel 21; secondly, during mortar application, the handle 23 applies pressure to the trowel 21, ensuring a tight fit with the mortar-holding section 01, preventing mortar leakage. It also prevents the trowel 21 from being squeezed by the mortar in the mortar-holding section 01, which could cause excessive stress on the sliding device 24 and breakage, thus extending the service life of the troweling and leak-proof device.

[0044] like Figure 1 As shown, the inclination of the inclined plane 123 of the first sidewall 11 and the second sidewall 13 is 45 degrees.

[0045] The first and second side walls 11 and 13 are right-angled trapezoids. Their inclined surfaces 123 have a certain degree of inclination. Based on extensive construction practice and experience, the optimal inclination is 45 degrees. Of course, other degrees can also be set. When the inclination is 45 degrees, on the one hand, it ensures that the material holding part 01 has a sufficiently large capacity. On the other hand, during the material distribution process, the 45-degree inclined surface 123 allows the masonry mortar to flow out from the discharge tooth 22 at a more suitable speed and angle under the action of gravity. Construction workers can more easily control the discharge amount and speed as needed, avoiding problems such as uneven material distribution or excessive waste caused by the mortar flowing out too fast or too slow.
