Description

Technical Field

[0001] This invention relates to the field of building wall plastering construction technology, and in particular to a building plastering process and its plastering device. Background Technology

[0002] Wall plastering refers to the application of cement mortar, mixed mortar, or lime mortar to the surface of walls. Interior and exterior wall plastering is a process performed after the completion of building structure construction. Proper plastering can provide functions such as moisture protection, weathering prevention, and heat insulation, preventing the building walls from being eroded by wind, rain, and snow.

[0003] Most interior wall plastering construction nowadays includes the following steps: plastering with mortar spots, wire mesh installation, first plaster layer, and second plaster finish layer. During construction, longitudinal ribs of the same thickness as the mortar spots are usually built on the wall to control the thickness of the mortar spots. However, in this construction process, the plastering material still needs to be applied to the wall manually using a plastering board. This application method requires a high level of skill from the construction workers. In addition, the plastering board is small, and the area covered each time is small. Furthermore, some plastering material will fall off under gravity during the application process, resulting in low plastering efficiency. Summary of the Invention

[0004] The purpose of this invention is to provide a plastering process and device for building construction in order to solve the problem of low plastering efficiency.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] A plastering device for building construction includes longitudinal ribs fixedly connected to a wall. The top and bottom of each longitudinal rib abut against the roof and floor, respectively. Multiple longitudinal ribs are arranged at longitudinal intervals. The top and bottom ends of each longitudinal rib are detachably connected to transversely distributed positioning ribs. A positioning plate is provided on the front side of each longitudinal rib, abutting against it. The top and bottom rear sides of the positioning plate have positioning recesses that fit with the transverse positioning ribs. The longitudinal ribs have a detachable multi-layered structure. The transverse width of the positioning plate is greater than the spacing between adjacent longitudinal ribs. The plastering device also includes a feeding mechanism communicating with the positioning plate. The top front side of the positioning plate has a pressure relief return pipe communicating with the top rear side of the positioning plate.

[0007] As a further description of the above technical solution:

[0008] The feeding mechanism includes a movable base with a stirring assembly on it. The stirring assembly is connected to multiple conveying hoses via a pump, and the ends of the conveying hoses are detachably connected to the positioning plate.

[0009] As a further description of the above technical solution:

[0010] The ends of the multiple delivery hoses are longitudinally spaced at the points where they connect with the positioning plate.

[0011] As a further description of the above technical solution:

[0012] The stirring assembly includes a stirring tank mounted on top of a movable base, a stirring frame rotating inside the stirring tank, a drive motor for driving the stirring frame to rotate mounted on the bottom of the movable base, an input end of a pump connected to the stirring tank, and a free end of a pressure relief return pipe connected to the stirring tank.

[0013] As a further description of the above technical solution:

[0014] The lateral width of the positioning plate is 1.5-2 times the spacing between adjacent longitudinal ribs, and the ends of the plurality of conveying hoses are located on the vertical centerline of the positioning plate.

[0015] As a further description of the above technical solution:

[0016] A handle is fixedly connected to the front side of the positioning plate.

[0017] As a further description of the above technical solution:

[0018] A plastering process for building construction includes the following steps:

[0019] S1. Customize longitudinal ribs according to the thickness of the wall plaster spots and the first plaster layer as needed. The longitudinal ribs are two-layer structures with the same thickness as the plaster spot thickness and the first plaster layer thickness and can be disassembled and assembled. Cut the customized longitudinal ribs into multiple pieces with the same height as the wall to be plastered.

[0020] S2. Leave a 40-50cm interval at the corner of the wall to be plastered as the initial installation position of the first longitudinal reinforcement bar. Mark the installation positions of subsequent longitudinal reinforcement bars along the wall to be plastered, 60-80cm apart from the initial installation position of the first longitudinal reinforcement bar.

[0021] S3. Grind the vertical strips at the vertical installation position of each longitudinal rib. Use a laser level to control the grinding position so that the installation position of each longitudinal rib is on the same plane.

[0022] S4. Fix one layer of each longitudinal rib with the same thickness as the plaster spot to the installation position of each longitudinal rib on the wall. Then cut two horizontal positioning ribs with the same width as the horizontal width of the wall to be plastered. Fix the two horizontal positioning ribs to the top and bottom of the front side of multiple longitudinal ribs with bolts.

[0023] S5. Remove the burrs from the wall surface, then wet the wall and place the positioning plate on the front side of the first and second longitudinal ribs. The positioning notch of the positioning plate should fit with the transverse positioning rib. The mixed ash paste material is fed into the area between the positioning plate and the wall through the feeding mechanism. The positioning plate is slid back and forth along the transverse positioning rib to make the ash paste material evenly applied to the area between the two longitudinal ribs.

[0024] S6. After the mortar spots in the area between the two longitudinal ribs are evenly applied, slide the positioning plate to the area between the two adjacent longitudinal ribs to apply the mortar spot material until the mortar spot material in the last area is applied.

[0025] S7. Remove the horizontal positioning ribs, then manually apply mortar to the area where the first and last longitudinal ribs meet the wall edge. After sliding the horizontal bar up and down with the two adjacent longitudinal ribs, smooth the manually applied mortar.

[0026] S8. After the plaster has set, fix the metal mesh to the front of the plaster. The edge of the metal mesh should be in contact with the longitudinal ribs. Then fix the longitudinal ribs and the second layer of longitudinal ribs with the same thickness as the first plaster layer to the upper layer of longitudinal ribs with bolts. Fix the metal mesh with the two layers of longitudinal ribs.

[0027] S9. Perform a fixed slurry application operation between the metal mesh and the ash cake;

[0028] S10. The second layer of the horizontal positioning rib and the longitudinal rib is fixed by bolts. After the positioning plate is attached to the horizontal positioning rib and the longitudinal rib, the first plaster layer is applied by repeating steps S5 and S6.

[0029] S11. Disassemble the transverse positioning ribs. In the initial setting state of the first plaster layer, attach the mesh cloth to the first plaster layer, and then scrape the second plaster surface layer onto the outside of the first plaster layer until the second plaster surface layer covers the mesh cloth and longitudinal ribs and then smooths it.

[0030] In summary, due to the adoption of the above technical solution, the beneficial effects of the present invention are:

[0031] By using multiple longitudinal ribs, the wall is divided into several areas. Horizontal positioning ribs, along with the positioning notch of the positioning plate, prevent material from overflowing from the top and bottom of the positioning plate during the pouring process. The longitudinal ribs form a detachable, multi-layered structure, allowing for precise control of the thickness of each layer during plastering. The horizontal width of the positioning plate is greater than the spacing between adjacent longitudinal ribs, ensuring stable and complete coverage of the area between them. When the feeding mechanism pours material into the area behind the positioning plate, it can slide laterally, ensuring uniform material pouring within a given area. After pouring material into one area, the positioning plate slides directly to the next area, improving the efficiency of each layer and solving the problem of low plastering efficiency.

[0037] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0038] Please see Figure 1-3This invention provides a technical solution: a plastering device for building engineering, including longitudinal ribs 9 fixedly connected to the wall, the top and bottom of the longitudinal ribs 9 abutting against the roof and the floor respectively, and multiple longitudinal ribs 9 are distributed longitudinally at intervals. The front sides of the top and bottom ends of the multiple longitudinal ribs 9 are detachably connected to transverse positioning ribs 10 distributed laterally. The front side of the longitudinal ribs 9 is provided with a positioning plate 6 abutting against the longitudinal ribs 9. The top and bottom rear sides of the positioning plate 6 have positioning notches 601 that fit with the transverse positioning ribs 10. The longitudinal ribs 9 are detachable multi-layer structures. The transverse width of the positioning plate 6 is greater than the spacing between adjacent longitudinal ribs 9. The plastering device also includes a feeding mechanism communicating with the positioning plate 6. The front side of the top of the positioning plate 6 has a pressure relief return pipe 11 communicating with the rear side of the top of the positioning plate 6.

[0039] The wall is divided into multiple areas by the setting of multiple longitudinal ribs 9. The horizontal positioning ribs 10, through which the positioning recess 601 of the positioning plate 6 abuts and slides against the horizontal positioning ribs 10, prevent material from overflowing from the top and bottom of the positioning plate 6 during the injection process to the rear side of the positioning plate 6. The longitudinal ribs 9 have a detachable multi-layer structure, making it suitable for controlling the thickness of each layer of material during plastering. The horizontal width of the positioning plate 6 is greater than the spacing between adjacent longitudinal ribs 9, ensuring that the positioning plate 6 can stably hold adjacent longitudinal ribs 9 in place. The area between the ribs 9 is completely covered, so when the feeding mechanism injects material into the rear side of the positioning plate 6, the positioning plate 6 can slide laterally, ensuring the uniformity of material injection in a region. After the material injection in one region is completed, the positioning plate 6 can be slid directly to the next region for material injection, improving the efficiency of material injection in each layer. The pressure relief return pipe 11 is set to relieve pressure on the rear side of the positioning plate 6 during the injection process of the feeding mechanism. At the same time, the return flow of the pressure relief return pipe 11 is used to control the injection, thereby appropriately adjusting the feeding rate.

[0040] Specifically, such as Figure 1 As shown, the feeding mechanism includes a movable base 1, on which a stirring assembly is mounted. Multiple conveying hoses 7 are connected to the stirring assembly via a pump 5, and the ends of the conveying hoses 7 are detachably connected to a positioning plate 6.

[0041] Specifically, such as Figure 1 As shown, the ends of multiple delivery hoses 7 are longitudinally spaced at the connection points with the positioning plate 6.

[0042] This ensures that the positioning plate 6 can be fed in multiple vertical layers. In actual distribution, since the material will flow downward under the action of gravity, the multiple conveying hoses 7 distributed longitudinally can be densely arranged above the vertical layer and loosely arranged below, further ensuring the uniformity of feeding. In addition, a control valve is set at the end of the conveying hose 7. During the actual feeding process, when the return flow of the pressure relief return pipe 11 increases, the control valve of the conveying hose 7 located below the vertical layer can be closed, and the feeding efficiency in the feeding mechanism of the machine can be adjusted to prevent the feeding rate from being too high when the area behind the positioning plate 6 is about to overflow, which would cause excessive pressure on the rear side of the positioning plate 6.

[0043] Specifically, such as Figure 1 As shown, the mixing assembly includes a mixing tank 2 mounted on top of a movable base 1, a mixing frame 3 rotating inside the mixing tank 2, a drive motor 4 for driving the mixing frame 3 to rotate mounted on the bottom of the movable base 1, an input end of a pump 5 connected to the mixing tank 2, and a free end of a pressure relief return pipe 11 connected to the mixing tank 2.

[0044] The mixing assembly can be configured to directly transport the mixed material into the mixing tank 2, and drive the mixing frame 3 to rotate via the drive motor 4, thereby preventing material sedimentation. Alternatively, unmixed raw materials can be transported into the mixing tank 2 for mixing and then transported to the rear of the positioning plate 6 via the pump 5. The pressure relief return pipe 11 is connected to the mixing tank 2, which can return the plastering material to the inside of the mixing tank 2.

[0045] Specifically, such as Figure 1 As shown, the lateral width of the positioning plate 6 is 1.5-2 times the spacing between adjacent longitudinal ribs 9, and the ends of multiple conveying hoses 7 are located on the vertical centerline of the positioning plate 6.

[0046] The lateral width of the positioning plate 6 is 1.5-2 times the spacing between adjacent longitudinal ribs 9, so that when the conveying hose 7 is located in the middle of the positioning plate 6, the output end of the conveying hose 7 can take into account the area formed by an adjacent longitudinal rib 9 as much as possible during the lateral sliding process of the positioning plate 6.

[0047] Specifically, such as Figure 1 As shown, a handle 8 is fixedly connected to the front side of the positioning plate 6.

[0048] The handle 8 is designed to facilitate manual sliding of the positioning plate 6 laterally.

[0049] Specifically, such as Figure 1-3 As shown, a plastering process for building construction includes the following steps:

[0050] S1. Customize longitudinal ribs 9 according to the thickness of the wall plaster spots and the first plaster layer as required. The longitudinal ribs 9 are two-layer structures with the same thickness as the thickness of the plaster spots and the first plaster layer, and can be disassembled and assembled. Cut the customized longitudinal ribs 9 into multiple pieces with the same height as the wall to be plastered.

[0051] S2. Leave a 40-50cm interval at the corner of the wall to be plastered as the initial installation position of the first longitudinal stiffener 9. Mark the installation positions of subsequent longitudinal stiffeners 9 along the wall to be plastered, 60-80cm apart from the initial installation position of the first longitudinal stiffener 9.

[0052] S3. Grind the vertical strips flat at the vertical installation position of each longitudinal rib 9. Use a laser level to control the grinding position so that the installation position of each longitudinal rib 9 is on the same plane.

[0053] S4. Fix one layer of each longitudinal stiffener 9 with the same thickness as the plaster spot to the installation position of each longitudinal stiffener 9 on the wall. Then cut two horizontal positioning stiffeners 10 with the same horizontal width as the wall to be plastered. Fix the two horizontal positioning stiffeners 10 to the top and bottom of the front side of multiple longitudinal stiffeners 9 with bolts.

[0054] S5. Remove the burrs from the wall surface, then wet the wall, and cover the front side of the first and second longitudinal ribs 9 with the positioning plate 6, and the positioning notch 601 of the positioning plate 6 is in contact with the transverse positioning rib 10. The mixed ash paste material is fed into the area between the positioning plate 6 and the wall through the feeding mechanism. The positioning plate 6 is slid back and forth along the transverse positioning rib 10 to make the ash paste material evenly applied to the area between the two longitudinal ribs 9.

[0055] S6. After the mortar patch is evenly applied in the area between the two longitudinal ribs 9, slide the positioning plate 6 to the area between the two adjacent longitudinal ribs 9 to apply the mortar patch material until the mortar patch material is applied in the last area.

[0056] S7. Disassemble the horizontal positioning rib 10, then manually apply mortar to the area where the first longitudinal rib 9 and the last longitudinal rib 9 meet the wall edge. Then slide the horizontal bar up and down after it is attached to the two adjacent longitudinal ribs 9 to smooth the manually applied mortar.

[0057] S8. After the plaster has set, fix the metal mesh to the front of the plaster. The edge of the metal mesh should be in contact with the longitudinal rib 9. Then fix the longitudinal rib 9 and the second longitudinal rib 9 with the same thickness as the first plaster layer to the upper longitudinal rib 9 with bolts. Fix the metal mesh with the two longitudinal ribs 9.

[0058] S9. Perform a fixed slurry application operation between the metal mesh and the ash cake;

[0059] S10. The second layer of the horizontal positioning rib 10 and the longitudinal rib 9 is fixed by bolts. Then, the positioning plate 6 is attached to the horizontal positioning rib 10 and the longitudinal rib 9. Repeat steps S5 and S6 to apply the first plaster layer.

[0060] S11. Disassemble the transverse positioning ribs 10. In the initial setting state of the first plaster layer, attach the mesh cloth to the first plaster layer, and then scrape the second plaster surface layer to the outside of the first plaster layer until the second plaster surface layer covers the mesh cloth and longitudinal ribs 9 and then smooths it.

[0061] This plastering process, with its multi-layered structure of varying thicknesses for the longitudinal ribs 9, facilitates control over the thickness of each plaster layer. The positioning plate 6 forms a material injection zone between adjacent longitudinal ribs 9. The material in the injection zone is shaped by the rear face of the positioning plate 6, resulting in a smooth plastering layer. The positioning plate 6 slides to different material injection zones, enabling rapid material injection and shaping of the wall, thus improving construction efficiency. Furthermore, the stability of the metal mesh is ensured by fixing the edges of the metal mesh between the two layers of the longitudinal ribs 9, given that the longitudinal ribs 9 are multi-layered structures of varying thicknesses.

[0062] The above description is only a preferred embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in the present invention, based on the technical solution and inventive concept of the present invention, should be covered within the scope of protection of the present invention.
