Description

Technical Field

[0001] This application relates to the field of ceramic tile layout technology, and in particular to a method for applying intelligent tile layout based on BIM technology. Background Technology

[0002] In the process of home decoration and renovation, the laying of tiles on the floors and walls is undoubtedly a crucial step. It not only directly affects the overall aesthetics of the interior space but is also a key component supporting practical functions. A smooth and clean tile surface enhances the cleanliness and texture of the space, while precise laying techniques ensure the durability of the floors and walls, preventing problems such as hollow spots and tile detachment due to improper installation. This directly impacts the comfort and safety of living, making it an indispensable part of creating a beautiful and practical living environment. Before tiling, workers need to meticulously measure the floor and walls of the house. This includes accurately measuring the length, width, and height of the space, as well as the dimensions of key locations such as corners, doorways, and window openings, based on which the tile layout is planned. During the tile layout process, factors such as the tile size, texture direction, and spatial layout must be comprehensively considered to rationally design the tile arrangement, ensuring a continuous pattern and neat joints after installation. Simultaneously, the amount of tile cutting should be minimized to maximize material utilization and lay a solid foundation for subsequent tiling work. The common method of tiling is to start from the edge and lay the tiles sequentially. While this method is relatively simple and direct, it has certain problems in practical application. Laying tiles from the edge without scientifically planning according to the spatial boundaries results in low utilization of whole tiles and significant cutting waste. Furthermore, when dealing with key locations such as spatial layouts, doorways, and external corners, it's difficult to flexibly adjust the starting point, easily leading to chaotic tile arrangement, visual breaks, and damage to the overall aesthetics of the space. Summary of the Invention

[0003] The purpose of this application is to address the problem mentioned in the background technology that when laying tiles, the starting point is often taken from the edge position without scientific planning based on the spatial boundary, resulting in low utilization of whole tiles. Furthermore, when facing key positions such as spatial layout, door openings, and external corners, the starting point cannot be flexibly adjusted, which easily leads to chaotic tile arrangement and visual breaks. This application provides a method for intelligent tile laying based on BIM technology.

[0004] To achieve the above objectives, this application specifically adopts the following technical solution: A method for intelligent bricklaying based on BIM technology, which includes the following steps: Step 1: Project Data Preparation: Obtain the Building Information Model according to the project type. The above project types include new projects and renovation projects. New projects are built using Revit to create a full-discipline BIM model. Renovation projects are built using a 3D laser scanner to obtain point cloud data, which is then preprocessed and used to create a BIM model using reverse modeling tools. Step 2: Setting brick laying parameters: Extract the boundary data of the spatial area based on the BIM model, and set the brick laying type, size specifications, material parameters and base thickness; Step 3, Intelligent Brick Laying Process: Set the starting point according to the brick laying parameters, generate a three-dimensional brick laying model according to the preset laying principle, and perform collision detection between the three-dimensional brick laying model and the building structure, electromechanical pipelines and end points. If there is a collision, adjust the layout logic until the constraint conditions are met. Step 4: Key Data Generation: Encode the bricks in the 3D bricklaying model, calculate the engineering quantities, generate detailed drawings of the processing dimensions, and convert the BIM model into a lightweight model; Step 5: Output construction guidance results: Output the plan and elevation system construction drawings, material statistics table, layout and processing detail drawings, and the lightweight model mentioned above, according to the drafting standards, to guide on-site construction.

[0005] Furthermore, the point cloud data preprocessing in step one includes multi-station registration, noise reduction, and thinning to eliminate equipment errors and redundant data.

[0006] Furthermore, in step two, the boundary data of the spatial area is extracted from the BIM model using a BIM plugin to ensure error-free control of the paving range.

[0007] Furthermore, the pre-set paving principles in step three include: floor tiles are laid out to both sides based on the center line of the entrance to ensure that the main passage is made of whole tiles; wall tiles are laid starting from the external corner, and tiles are symmetrically divided at door and window openings; cut tiles are used in the ceiling area, and whole tiles are used within the line of sight.

[0008] Furthermore, in step four, the coding adopts the form of spatial area, floor tile / wall tile, and serial number, and the engineering quantity statistics are performed according to preset key field parameters such as elevation, room type, paving type, material, specifications, area, thickness, and whether it is a whole tile.

[0009] Furthermore, the 3D laser scanner includes a mounting frame, inside which the laser scanner body is mounted. Rotary shafts are fixed on both sides of the laser scanner body, and these shafts are rotatably connected to the mounting frame. A touchscreen is mounted on the side of the laser scanner body, and a scanning head is mounted inside the laser scanner body. A rotating support is mounted at the lower end of the mounting frame, and a support leg is fixed at the lower end of the rotating support. An adjustment structure for vertical adjustment of the laser scanner body is provided between the mounting frame and the laser scanner body.

[0010] By adopting the above technical solution, when using this 3D laser scanner to scan indoor walls and floors, the support legs are placed on the ground to support the laser scanner body. Then, the parameters are adjusted via the touch screen to start scanning. During scanning, the mounting bracket drives the laser scanner body to rotate, thereby scanning the walls and floors. When the wall scanning is completed, if it is necessary to scan the floor and the junction of the wall and the floor, the vertical angle of the laser scanner body is adjusted by adjusting the structure so that the scanning head faces the ground, and then the rotation scanning is performed again.

[0011] Furthermore, the adjustment structure includes an adjustment tooth block fixed to the lower end of the laser scanner body, an adjustment shaft rotatably connected inside the mounting bracket, an adjustment gear meshing with the adjustment tooth block fixed on the adjustment shaft, a mounting housing fixed to the side of the mounting bracket, and a drive assembly provided on the mounting housing.

[0012] By adopting the above technical solution, the drive component works to drive the adjustment shaft to rotate, thereby causing the adjustment gear to drive the adjustment block to rotate, realizing the angle adjustment of the laser scanner body, which is more conducive to scanning the ground.

[0013] Furthermore, the drive assembly includes a servo motor fixed to the side of the mounting housing, the output end of the servo motor extending into the interior of the mounting housing and fixed with a drive shaft, a drive gear fixed on the drive shaft, and one end of the adjustment shaft extending into the interior of the mounting housing and fixed with a driven gear meshing with the drive gear.

[0014] By adopting the above technical solution, the servo motor drives the drive shaft to rotate, which in turn drives the driven gear to rotate, and finally drives the adjustment shaft to rotate, thus playing a transmission role.

[0015] Furthermore, the mounting bracket has a movable groove, a counterweight is slidably disposed inside the movable groove, a ball screw is rotatably connected inside the movable groove, a ball nut adapted to the ball screw is fixed inside the counterweight, and the counterweight is sleeved on the ball screw through the ball nut.

[0016] By adopting the above technical solution, when the scanning head is adjusted to face the ground, the counterweight will gradually extend out of the movable groove when the ball screw rotates, so that the mounting frame is evenly weighted, making subsequent scanning more stable.

[0017] Furthermore, a first bevel gear is fixed on the ball screw, the end of the drive shaft away from the servo motor extends into the movable groove and is rotatably connected to the mounting bracket, and a second bevel gear that meshes with the first bevel gear is fixed at the end of the drive shaft that extends into the movable groove.

[0018] By adopting the above technical solution, when the drive shaft rotates, it drives the second bevel gear to rotate, and the rotation of the second bevel gear drives the rotation of the first bevel gear, thereby causing the ball screw to rotate and playing a transmission role.

[0019] In summary, this application includes at least one of the following beneficial effects; 1. This application describes a tiling method that uses a 3D laser scanner to precisely collect point cloud data and combines it with a BIM plugin to extract room and surface data from the model, achieving precise control over the tiling area. Simultaneously, setting the starting point based on the boundary for whole-brick tiling effectively reduces cutting waste. The resulting 3D tiling model allows for flexible adjustment of the starting point according to spatial layout, doorways, and external corners, ensuring visual continuity and providing convenient and efficient technical support for subsequent tiling construction.

[0020] 2. In this application, when scanning the ground and the junction of the wall and the ground is required, the servo motor is controlled to rotate its output end clockwise. Then, under the action of the drive shaft, the driving gear, the driven gear, and the adjusting shaft, the adjusting gear rotates. The rotation of the adjusting gear, in turn, drives the laser scanner body to rotate, so that the scanning head faces the ground, thus completing the angle adjustment of the scanning head. By adjusting the angle of the scanning head, the problem of frequently moving the laser scanner due to incomplete scanning of the ground and the junction of the wall and the ground can be effectively reduced.

[0021] 3. In this application, by adjusting the vertical angle of the scanning head before scanning, the scanning accuracy can be improved, making the scanned data clearer and providing a better foundation for subsequent tile layout.

[0022] 4. When the drive shaft drives the adjustment shaft to adjust the angle of the laser scanner body, the rotation of the second and first bevel gears causes the ball screw to rotate, which in turn forces the ball nut inside the counterweight. Simultaneously, the counterweight is restricted by the movable groove, causing it to gradually extend out of the groove. During vertical angle adjustment of the laser scanner, the counterweight moves synchronously, resulting in a more even distribution of weight across the entire mounting frame. This effectively prevents changes in the counterweight during laser scanner body angle adjustment, avoiding instability and potential displacement or tilting of the scanner when it rotates to drive the laser scanner body for scanning. This improves the stability of the scanning process. Attached Figure Description

[0025] The following is in conjunction with the appendix Figures 1-4 This application will be described in further detail.

[0026] This application discloses a method for intelligent bricklaying based on BIM technology.

[0027] A method for intelligent bricklaying based on BIM technology, which includes the following steps: Step 1: Project Data Preparation: Obtain the Building Information Model according to the project type. The above project types include new projects and renovation projects. New projects are built using Revit to create a full-discipline BIM model. Renovation projects are built using a 3D laser scanner to obtain point cloud data, which is then preprocessed and used to create a BIM model using reverse modeling tools. Step 2: Setting brick laying parameters: Extract the boundary data of the spatial area based on the BIM model, and set the brick laying type, size specifications, material parameters and base thickness; Step 3, Intelligent Brick Laying Process: Set the starting point according to the brick laying parameters, generate a three-dimensional brick laying model according to the preset laying principle, and perform collision detection between the three-dimensional brick laying model and the building structure, electromechanical pipelines and end points. If there is a collision, adjust the layout logic until the constraint conditions are met. Step 4: Key Data Generation: Encode the bricks in the 3D bricklaying model, calculate the engineering quantities, generate detailed drawings of the processing dimensions, and convert the BIM model into a lightweight model; Step 5: Output construction guidance results: Output the plan and elevation system construction drawings, material statistics table, layout and processing detail drawings and lightweight model according to the drafting standards to guide on-site construction.

[0028] Step one, point cloud data preprocessing, includes multi-station registration, noise reduction, and thinning to eliminate equipment errors and redundant data.

[0029] In step two, the boundary data of the spatial area is extracted from the BIM model using a BIM plugin to ensure error-free control of the paving range.

[0030] The pre-set tiling principles in step three include: floor tiles are laid out from the center line of the entrance to both sides to ensure that the main passage is made of whole tiles; wall tiles are laid starting from the external corner, and tiles are symmetrically divided at door and window openings; cut tiles are used in the ceiling area, and whole tiles are used within the line of sight.

[0031] In step four, the coding adopts the form of spatial area + floor tile / wall tile + serial number. The quantity of work is calculated according to the preset key field parameters such as elevation, room type, paving type, material, specifications, area, thickness and whether it is a whole tile.

[0032] This tiling method uses a 3D laser scanner to precisely collect point cloud data and combines it with a BIM plugin to extract room and surface data from the model, enabling precise control over the tiling area. Simultaneously, setting the starting point based on the boundary for whole-brick laying effectively reduces cutting waste. The resulting 3D tiling model allows for flexible adjustment of the starting point according to spatial layout, doorways, and external corners, ensuring visual continuity and providing convenient and efficient technical support for subsequent tiling construction.

[0033] Reference Figures 1-3The 3D laser scanner includes a mounting frame 1, inside which a laser scanner body 11 is installed. Rotary shafts 12 are fixed on both sides of the laser scanner body 11, and the shafts 12 are rotatably connected to the mounting frame 1. A touch screen 13 is installed on the side of the laser scanner body 11. A scanning head 14 is installed inside the laser scanner body 11. A rotating support 15 is installed at the lower end of the mounting frame 1, and a support leg 16 is fixed at the lower end of the rotating support 15. An adjustment structure for vertical adjustment of the laser scanner body 11 is provided between the mounting frame 1 and the laser scanner body 11.

[0034] When using this 3D laser scanner to scan indoor walls and floors, support the support leg 16 on the ground, then install the mounting bracket 1 on the bracket. After adjusting the parameters via the touch screen 13, start scanning. During scanning, the mounting bracket 1 drives the laser scanner body 11 to rotate under the action of the rotating support 15, thereby scanning the walls and floors. When the wall scanning is completed, and it is necessary to scan the floor and the junction of the wall and the floor, adjust the vertical angle of the laser scanner body 11 by adjusting the structure so that the scanning head 14 faces the ground, and then rotate and scan again.

[0035] The adjustment structure includes an adjustment tooth block 2 fixed to the lower end of the laser scanner body 11, an adjustment shaft 21 rotatably connected inside the mounting frame 1, an adjustment gear 22 that meshes with the adjustment tooth block 2 fixed on the adjustment shaft 21, a mounting housing 23 fixed to the side of the mounting frame 1, and a drive assembly provided on the mounting housing 23.

[0036] The drive assembly includes a servo motor 24 fixed to the side of the mounting housing 23. The output end of the servo motor 24 extends into the interior of the mounting housing 23 and is fixed with a drive shaft 241. A drive gear 242 is fixed on the drive shaft 241. One end of the adjusting shaft 21 extends into the interior of the mounting housing 23 and is fixed with a driven gear 243 that meshes with the drive gear 242.

[0037] When scanning the ground and the junction between the wall and the ground, the servo motor 24 is controlled to rotate clockwise. This clockwise rotation of the servo motor 24 drives the drive shaft 241 to rotate, which in turn drives the drive gear 242. The drive gear 242 then drives the driven gear 243, which in turn drives the adjusting shaft 21. This, in turn, drives the adjusting gear 22, which in turn rotates the laser scanner body 11, causing the scanning head 14 to face the ground, thus adjusting the angle of the scanning head 14. Adjusting the angle of the scanning head 14 effectively reduces the need for frequent movement of the laser scanner due to incomplete scanning at the ground and the junction between the wall and the ground. Furthermore, adjusting the vertical angle of the scanning head 14 improves scanning accuracy, resulting in clearer scanned data and providing a better foundation for subsequent tile layout.

[0038] When the scanning is completed and the laser scanner body 11 needs to be reset, the servo motor 24 is controlled to work, so that its output end rotates counterclockwise. Then, under the action of the drive shaft 241, the drive gear 242, and the driven gear 243, the adjusting shaft 21 drives the adjusting gear 22 to rotate, thereby resetting the laser scanner body 11.

[0039] Reference Figures 2-4 The mounting bracket 1 has a movable groove 25, and a counterweight 251 is slidably arranged inside the movable groove 25. A ball screw 252 is rotatably connected inside the movable groove 25. A ball nut that matches the ball screw 252 is fixed inside the counterweight 251. The counterweight 251 is sleeved on the ball screw 252 through the ball nut.

[0040] The ball screw 252 is fixed with a first bevel gear 253, the end of the drive shaft 241 away from the servo motor 24 extends into the movable groove 25 and is rotatably connected to the mounting bracket 1, and the end of the drive shaft 241 extending into the movable groove 25 is fixed with a second bevel gear 254 that meshes with the first bevel gear 253.

[0041] When the drive shaft 241 drives the adjustment shaft 21 to rotate, the second bevel gear 254 on the drive shaft 241 rotates accordingly. The rotation of the second bevel gear 254 drives the first bevel gear 253 to rotate, causing the ball screw 252 to rotate. The rotation of the ball screw 252 causes the ball nut inside the counterweight block 251 to be stressed. Simultaneously, the counterweight block 251 is restricted by the movable groove 25, thus gradually extending out from inside the movable groove 25. When the laser scanner's vertical angle is adjusted, the counterweight block 251 moves synchronously, making the weight distribution of the entire mounting frame 1 more uniform. This effectively prevents changes in the weight distribution of the mounting frame 1 when the laser scanner body 11 is adjusted, avoiding instability of the entire mounting frame 1 and preventing offset or tilting of the entire scanner when the mounting frame 1 drives the laser scanner body 11 to rotate for scanning. This improves the stability of the scanning process.

[0042] Working principle: When using this 3D laser scanner to scan indoor walls and floors, support leg 16 is placed on the ground, and then mounting bracket 1 is installed on the bracket. After adjusting the parameters through touch screen 13, scanning begins. During scanning, under the action of rotating support 15, mounting bracket 1 drives laser scanner body 11 to rotate, thereby scanning the walls and floors. After the wall scanning is completed, when scanning the floor and the junction between the wall and the floor is required, the servo motor 24 is controlled to rotate clockwise. This clockwise rotation of the servo motor 24 drives the drive shaft 241 to rotate, which in turn drives the drive gear 242 to rotate. The drive gear 242 then drives the driven gear 243 to rotate, which in turn drives the adjusting shaft 21 to rotate. This, in turn, drives the adjusting gear 22 to rotate, which in turn rotates the laser scanner body 11, causing the scanning head 14 to face the floor, thus adjusting the angle of the scanning head 14. By adjusting the angle of the scanning head 14, the problem of frequently moving the laser scanner due to incomplete scanning of the floor and the junction between the wall and the floor can be effectively reduced. When the drive shaft 241 drives the adjustment shaft 21 to rotate and adjust the angle of the laser scanner body 11, the second bevel gear 254 on the drive shaft 241 rotates accordingly. When the second bevel gear 254 rotates, it drives the first bevel gear 253 to rotate, causing the ball screw 252 to rotate. When the ball screw 252 rotates, the ball nut inside the counterweight block 251 is subjected to force. At the same time, the counterweight block 251 is restricted by the movable groove 25, thus gradually extending out from inside the movable groove 25. When the laser scanner is adjusted vertically, the counterweight block 251 moves synchronously, making the weight distribution of the entire mounting frame 1 more uniform. This effectively avoids changes in the weight distribution of the mounting frame 1 when the laser scanner body 11 is adjusted, which could cause instability in the entire mounting frame 1 and lead to offset or tilting of the entire scanner when the mounting frame 1 drives the laser scanner body 11 to rotate for scanning. This improves the stability of the scanning process. When the scanning is completed and the laser scanner body 11 needs to be reset, the servo motor 24 is controlled to work, causing its output end to rotate counterclockwise. Then, under the action of the drive shaft 241, the drive gear 242, and the driven gear 243, the adjusting shaft 21 drives the adjusting gear 22 to rotate, thereby resetting the laser scanner body 11. When the output end of the servo motor 24 rotates counterclockwise, under the action of the second bevel gear 254 and the first bevel gear 253, the ball nut rotates, thereby causing the counterweight 251 to gradually retract into the movable groove 25.
