[0002] In the field of modern timber-framed construction, with the increasing emphasis on timber as a renewable, low-carbon, and environmentally friendly building material, the development of lightweight and efficient timber-framed floor systems is of paramount importance for improving timber utilization efficiency and reducing construction costs. However, a series of problems urgently need to be addressed in the actual application and construction of timber-framed floors.
[0003] From a construction technology perspective, existing timber floor slab construction processes are complex and inefficient. Traditional construction methods largely rely on extensive manual labor, which is not only labor-intensive but also makes it difficult to guarantee construction accuracy. Especially in the component installation and connection stages, complex procedures can easily lead to the accumulation of construction errors, thereby affecting the stability and safety of the entire floor slab structure. In addition, the construction process requires a large number of customized molds or supporting structures to assist in construction, which undoubtedly increases production costs and construction complexity, resulting in low assembly efficiency for timber ribbed floor slabs. Summary of the Invention
[0004] The main objective of this application is to provide a method for manufacturing and assembling wooden ribbed floor slabs, which aims to solve the technical problem of low assembly efficiency of wooden ribbed floor slabs.
[0005] To achieve the above objectives, this application proposes a method for manufacturing and assembling wooden ribbed floor slabs, the method comprising:
[0006] The robot picks up pre-processed timber from the material table, and after the end connection surfaces are cut by the CNC platform, the timber to be assembled is obtained.
[0007] Position the timber to be assembled onto the pre-installed wooden floor load-bearing panel, and use a pneumatic nail gun to fix the timber to be assembled onto the wooden floor load-bearing panel to complete the installation of the circumferential secondary ribs.
[0008] According to the preset assembly plan, apply wood structure adhesive evenly to the preset contact surface between the laminated wood strips to be assembled and the wooden floor load-bearing panel.
[0009] Using the circumferential secondary rib as a template, the laminated wood strips are bent into radial main ribs by a robot, and self-tapping screws are installed to complete the node connection.
[0010] Self-tapping screws are used to connect the column head nodes to the wooden floor load-bearing panel, thereby centrally transmitting the end shear force of the radial main ribs to the supporting column;
[0011] Through the processes of floor slab flipping and top reinforcement, the robot adds self-tapping screws to complete the assembly of the wooden ribbed floor slab.
[0012] Optionally, standardized timber prefabricated circumferential secondary ribs are used, and according to the assembly scheme, the circumferential secondary ribs serve as bending templates for the radial main ribs during construction, and are retained as structural components after construction is completed.
[0013] Optionally, the robot is equipped with a pneumatic gripper and an electric screw tool end, which, in conjunction with a CNC machining tool, completes the end processing and installation of the circumferential secondary rib component, and achieves the bending and forming of the radial main rib by applying pressure through the screw.
[0014] Optionally, the column head node uses a hardwood cover plate as a connecting member, which is fixedly connected to the end of the radial main rib by self-tapping screws.
[0015] Optionally, after the floor slab is flipped, the robot can install additional top screws at the main rib locations to enhance the overall rigidity and stability of the floor slab.

[0019] Optionally, during the process of the robot installing circumferential secondary ribs and bending radial main ribs, the positional accuracy and bending shape of the timber are monitored in real time by a laser scanner or vision sensor. The monitoring data is fed back to the control system, which automatically adjusts the robot's operating parameters according to the deviation to ensure that the assembly accuracy meets the design requirements.
[0020] Optionally, a waterproof sealing layer is provided between the load-bearing panel of the wooden floor slab and the circumferential secondary ribs and radial main ribs. The waterproof sealing layer is made of waterproof coating or sealing tape to prevent moisture intrusion that could lead to wood decay or a decline in structural performance.
[0021] This application proposes a method for manufacturing and assembling wooden ribbed floor slabs.

Understandably, this application uses robots to accurately cut and position the timber, and the robots bend the laminated wood strips to achieve precise installation of the rib curves, ultimately improving the assembly efficiency of the wooden rib floor slab.

[0034] It should be understood that the specific embodiments described herein are merely illustrative of the technical solutions of this application and are not intended to limit this application.
[0035] This application provides a method for manufacturing and assembling a wooden ribbed floor slab, referring to... Figure 1 , Figure 1 This is a flowchart illustrating the first embodiment of the method for manufacturing and assembling wooden ribbed floorboards according to this application.
[0036] In this embodiment, the method for manufacturing and assembling the wooden ribbed floorboards includes steps S10 to S60:
[0037] Step S10: The robot picks up the pre-processed timber from the material table, and after the end connection surface is cut by the CNC platform, the timber to be assembled is obtained.
[0038] Specifically, the robot picks up pre-processed timber from the material table. The length and cross-sectional dimensions of these timbers are predetermined according to design requirements. The robot then transfers the timber to a CNC platform, where the platform precisely cuts the end joints of the timber according to a pre-programmed procedure to ensure a tight fit with subsequent connecting components. After cutting, the timber becomes ready for assembly, preparing it for subsequent installation steps.
[0039] Step S20: Position the timber to be assembled onto the pre-installed wooden floor load-bearing panel, and use a pneumatic nail gun to fix the timber to be assembled onto the wooden floor load-bearing panel to complete the installation of the circumferential secondary ribs.
[0040] Specifically, the pre-installed wooden floor slab load-bearing panels can be materials with in-plane stiffness and uniform load transfer capabilities, such as cross-laminated timber (CLT) or oriented strand board (OSB). The robot precisely positions the timber to be assembled onto the pre-designed locations on the load-bearing panels, and then uses a pneumatic nail gun to firmly fix the timber to the panels, thus completing the installation of the circumferential secondary ribs. These circumferential secondary ribs serve as supports and formwork for the subsequent installation of the radial main ribs, playing a crucial role in the entire floor structure.
[0041] Step S30: According to the preset assembly plan, apply wood structure adhesive evenly to the preset contact surface between the laminated wood strip to be assembled and the wooden floor load-bearing panel.
[0042] Based on the pre-established assembly plan, determine the bonding areas between the laminated wood strips and the load-bearing wooden floor panels. Apply wood structural adhesive evenly to the pre-designed contact surfaces in these areas to ensure the bond strength and connection stability between the laminated wood strips and the load-bearing panels. The adhesive should be applied evenly and completely to fully utilize its bonding performance.
[0043] Step S40: Using the circumferential secondary rib as a template, the laminated wood strip is bent into radial main ribs by a robot, and self-tapping screws are installed to complete the node connection.
[0044] Using the pre-installed circumferential secondary ribs as bending templates, the robot bends the laminated wood strips along the shape of the circumferential secondary ribs to form radial main ribs. During the bending process, the robot applies uniform pressure to the laminated wood strips through its onboard electric screw tool end, gradually bending them into the designed shape. Simultaneously, self-tapping screws are installed at the connection nodes between the laminated wood strips and the circumferential secondary ribs, firmly connecting the two together to form a stable node structure.
[0045] Step S50: Use self-tapping screws to connect the column head node to the wooden floor load-bearing panel to centrally transfer the end shear force of the radial main rib to the support column;
[0046] The column head joint is a key component connecting the radial main ribs and the supporting columns, and is typically made of hardwood capping. Self-tapping screws are used to fix the column head joint to the load-bearing panel of the wooden floor slab, ensuring that the end shear force of the radial main ribs can be effectively transferred to the supporting columns through the column head joint, thereby guaranteeing the stability and load-bearing capacity of the entire floor structure.
[0047] Specifically, refer to Figure 1 The wooden ribbed floor slab includes radial main ribs 2, circumferential secondary ribs 3, and column head nodes 4. The radial main ribs 2 are formed by bending laminated wood strips along a pre-defined curved path, serving as the main load-bearing components, optimizing the bending moment transmission path, and improving the overall stiffness of the floor slab. The layers are connected by adhesive. The cross-section is rectangular, and the height is determined according to the floor slab span. The main ribs are first connected to the load-bearing panel 1 with adhesive. After the overall construction is completed, self-tapping screws are driven vertically into the radial main ribs 2 from the top of the load-bearing panel 1 to further reinforce the connection between the radial main ribs 2 and the load-bearing panel 1.
[0048] The circumferential secondary rib 3 is a segmented, polygonal line, perpendicular to the radial main rib 2, forming an orthogonal grid. Each segment is made of standard timber with a rectangular cross-section, cut to the appropriate length and angle at the ends. The circumferential secondary rib 3 is connected to the load-bearing panel 1 using a pneumatic nail gun. During construction, it serves as an in-situ bending template for the radial main rib 2, constraining its geometry. The radial main rib 2 is connected to the ends of the circumferential secondary rib 3 using self-tapping screws. During use, it provides lateral stiffness to the floor slab, preventing local buckling.
[0049] The column head node 4 uses a hardwood cover plate as a connecting component. The hardwood cover plate is fixedly connected to the end of the radial main rib 2 by high-strength self-tapping screws, which concentrates the end shear force of the radial main rib 2 to the support column 5.
[0050] In step S60, through the floor slab flipping and top reinforcement process, the robot adds self-tapping screws to complete the wooden rib floor slab assembly.
[0051] The floor slab is flipped over to reinforce the top. The robot then installs additional top screws at the main ribs to further enhance the overall rigidity and stability of the floor slab, ensuring its safety and reliability during use.
[0052] Specifically, refer to Figure 3 For a single floor slab module, robot 6 first precisely installs the circumferential secondary rib 3 component. It picks up pre-processed timber 10 from the material table 8, cuts the end connection surfaces 9 using a CNC platform, and positions the component 10 onto the floor slab load-bearing panel 1, securing it with a pneumatic nail gun. Next, the radial main rib 2 is formed and installed. Wood structure adhesive is evenly applied between the laminates 11 of the radial main rib 2 and on the contact surfaces with the load-bearing panel 1. Robot 6 first clamps the already installed circumferential secondary rib 3 to ensure the floor slab does not shift during bending. Then, using the installed circumferential secondary rib 3 as a natural bending template, robot 6, with the tool end 7, bends the laminated timber strips 11 into radial main rib 2. Manual assistance is used to install self-tapping screws to complete the node connection. Finally, through the floor slab flipping and top reinforcement process, robot 6 adds self-tapping screws to form a complete load-bearing system.
[0053] Optionally, standardized timber prefabricated circumferential secondary ribs are used, and according to the assembly scheme, the circumferential secondary ribs serve as bending templates for the radial main ribs during construction, and are retained as structural components after construction is completed.
[0054] The circumferential secondary ribs are prefabricated using standardized timber, which not only improves production efficiency but also reduces production costs. During construction, the circumferential secondary ribs serve as bending templates for the radial main ribs, providing precise geometry and stable support for their formation. After construction, the circumferential secondary ribs are retained as part of the floor slab structure, sharing the floor load with the radial main ribs and improving the overall structural performance of the floor slab.
[0055] Optionally, the robot is equipped with a pneumatic gripper and an electric screw tool end, which, in conjunction with a CNC machining tool, completes the end processing and installation of the circumferential secondary rib component, and achieves the bending and forming of the radial main rib by applying pressure through the screw.
[0056] Reference Figure 4 The robot's tool end includes a pneumatic gripper and an electric screw clamp. The pneumatic gripper, driven by a cylinder, holds the timber strips with two claws and is responsible for the installation and positioning of the circumferential secondary ribs. The electric screw clamp, driven by a motor, uses two horizontal screws to drive a metal claw, applying uniform pressure to the laminated timber strips to achieve the bending and shaping of the radial main ribs. This design of the robot's tool end enables the robot to efficiently and accurately complete the installation of circumferential secondary ribs and the bending and shaping of radial main ribs, improving assembly efficiency and quality.
[0057] Optionally, the column head node uses a hardwood cover plate as a connecting member, which is fixedly connected to the end of the radial main rib by self-tapping screws.
[0058] Hardwood caps possess high strength and rigidity, effectively transferring the end shear force of the radial main ribs to the supporting columns. At the column head joint, the hardwood caps are tightly connected to the ends of the radial main ribs using self-tapping screws, forming a robust joint structure. This connection method is not only simple to operate but also ensures the load-bearing capacity and connection stability of the joint.
[0059] Optionally, after the floor slab is flipped, the robot can install additional top screws at the main rib locations to enhance the overall rigidity and stability of the floor slab.
[0060] After the floor slab is flipped, the robot installs additional top screws at the main rib locations, further enhancing the overall rigidity and stability of the floor slab. The installation location and number of top screws are determined according to design requirements to ensure the safety and reliability of the floor slab under various loads.
[0061] Optionally, the load-bearing panels of the wooden floor slab are made of cross-laminated timber or oriented strand board, providing in-plane stiffness and uniform load transfer function.
[0062] Cross-laminated timber (CLT) and oriented strand board (OSB) are common load-bearing panel materials for wood-based flooring. CLT has high strength and stiffness, enabling it to withstand large loads; OSB, on the other hand, offers good dimensional stability and cost-effectiveness. The choice of these materials can be determined based on specific project requirements and design specifications to meet the performance requirements of the flooring.
[0063] Optionally, in the step of cutting the end connection surface through the CNC platform, the cutting angle is precisely calculated and adjusted according to the connection angle between the circumferential secondary rib and the radial main rib to ensure tight connection and precise assembly between components.
[0064] When cutting the end connecting surface on the CNC platform, the cutting angle is precisely calculated and adjusted according to the connection angle between the circumferential secondary rib and the radial main rib. High-precision CNC cutting technology ensures that the cut end connecting surface can tightly fit with the circumferential secondary rib and the radial main rib, thereby improving assembly accuracy and connection strength.
[0065] Optionally, during the process of bending the laminated wood strips into radial main ribs, a real-time monitoring and feedback control system is used to monitor the stress and deformation during the bending process to ensure the accuracy and quality of the bending process and to prevent the wood from cracking or being damaged during the bending process.
[0066] During the bending process of laminated wood strips, a real-time monitoring and feedback control system monitors stress and deformation in real time. Once the detected stress or deformation exceeds a preset threshold, the system automatically adjusts the robot's operating parameters, such as pressure and speed, to ensure the accuracy and quality of the bending process. Simultaneously, this real-time monitoring and feedback control helps prevent cracking or damage to the wood during bending, improving production efficiency and yield.
[0067] Optionally, during the process of the robot installing circumferential secondary ribs and bending radial main ribs, the positional accuracy and bending shape of the timber are monitored in real time by a laser scanner or vision sensor. The monitoring data is fed back to the control system, which automatically adjusts the robot's operating parameters according to the deviation to ensure that the assembly accuracy meets the design requirements.
[0068] During the robot's installation of circumferential secondary ribs and bending of radial main ribs, a laser scanner or vision sensor is used to monitor the positional accuracy and bending shape of the timber in real time. The monitoring data is fed back to the control system, which automatically adjusts the robot's operating parameters, such as position and posture, based on the deviations to ensure that the assembly accuracy meets design requirements. This real-time monitoring and feedback control technology significantly improves assembly accuracy and quality, and reduces the impact of human error.
[0069] Optionally, a waterproof sealing layer is provided between the load-bearing panel of the wooden floor slab and the circumferential secondary ribs and radial main ribs. The waterproof sealing layer is made of waterproof coating or sealing tape to prevent moisture intrusion that could lead to wood decay or a decline in structural performance.
[0070] To improve the durability and service life of timber ribbed floor slabs, a waterproof sealing layer is installed between the load-bearing panel and the circumferential secondary ribs and radial main ribs. This waterproof sealing layer, which can be made of waterproof coatings or sealing tape, effectively prevents moisture from penetrating the wood, thus avoiding wood decay or structural performance degradation. This waterproofing treatment is of great significance for improving the long-term stability and safety of the floor slab.
