Description

Technical Field

[0001] This invention relates to the field of building load-bearing slab applications, and in particular to a load-bearing slab structure used in metal roofing panel construction projects. Background Technology

[0002] Metal roofing panel construction refers to the process of using metal materials to cover the roof in a building project. Metal roofing panels are usually made of thin metal sheets, such as steel, aluminum, zinc or copper, while load-bearing panels are fixed to the wall for use so that people can walk on them.

[0003] The common method involves rotating a handle to drive a lead screw, which in turn causes the lead screw slider to slide up and down within a groove, thereby raising or lowering the load-bearing plate and adjusting its height to suit different construction needs.

[0004] However, because this method uses a single-panel load-bearing structure, it lacks an auxiliary structure that can be adjusted according to needs when personnel need to adopt various postures on the surface of the load-bearing panel during operation. This can easily lead to fatigue and discomfort, affecting construction efficiency and quality, and reducing the practicality of the load-bearing panel. Furthermore, when the load-bearing panel is under pressure, the stress concentration can lead to difficulty in bearing large loads, resulting in limited overall practicality of the load-bearing panel and affecting its effective use under different working conditions. Moreover, because the load-bearing panel of the single-panel structure lacks an external support structure, the load-bearing panel is prone to bending when personnel step on the end away from the wall, which can easily lead to safety accidents. This method cannot meet the working requirements of building load-bearing panels. Therefore, a load-bearing panel structure for metal roofing panel construction is proposed. Summary of the Invention

A first motor is inserted into the lower side of the assembly plate, and the top of the rotor of the first motor passes through the middle through slot. The first lead screw is coaxially connected to the top of the rotor of the first motor. Guide rods are inserted into the through slots on both the left and right sides. Slider blocks are sleeved on the outside of the guide rods and the first lead screw. A load-bearing plate is welded to the front side of the slider. An extension plate is installed at the front end of a load-bearing plate. A second motor is mounted on the front side of the extension plate via a bracket.

A second lead screw is coaxially connected to the outer end of the rotor of the second motor. A transmission block is screwed onto the outside of the second lead screw. Transmission arms are hinged to the left and right sides of the outside of the transmission block. A hinge block is installed on the top inner side of the transmission arm through a bearing. Connecting columns are installed on the left and right sides of the front part of the extension plate. A steel rope is connected to the outside of the connecting column. The outer end of the steel rope passes through the upper left and right sides of the assembly plate. A counterweight is installed on the outer end of the steel rope.

[0006] Preferably, the top end of the first lead screw is connected to the corresponding position of the top of the inner cavity of the through groove via a ball bearing, and reinforcing ribs are welded to the upper and lower ends of the load-bearing plate and the connection points of the sliders on the left and right sides.

[0007] Preferably, the upper surface of the load-bearing plate is covered with anti-slip rubber, and a groove is provided at the top center of the extension plate. A locking block is inserted into the groove, and the top of the locking block is connected to the bottom of the transmission block at the corresponding position.

[0008] Preferably, the rear end of the second lead screw is fitted with a mating plate via a ball bearing, the bottom end of the mating plate is connected to the corresponding position of the upper surface of the extension plate, and the top of the hinge block is connected to the corresponding position of the bottom of the support plate.

[0009] Preferably, the connection points between the assembly plate and the steel rope are hollow structures, and rollers are inserted into the cavities of the assembly plate through rotating shafts, with the steel ropes being secured inside the rollers.

[0010] Preferably, a flexible pad is laid on the top of the support plate, ventilation holes are opened inside the support plate, and an assembly cylinder is connected to the left side of the support plate.

[0011] Preferably, a rod is inserted inside the assembly cylinder, and both the assembly cylinder and the rod have through holes. The number of through holes inside the assembly cylinder is 3-6 sets.

[0012] Preferably, a spring is connected to the bottom of the through hole cavity inside the insertion rod, and a limiting pin is installed at the outer end of the spring, with the front end of the limiting pin penetrating the interior of the through hole.

[0013] Preferably, the outer end of the insertion rod is connected to an extension plate, the length of which is the same as the length of the support plate, and the top of the extension plate is arc-shaped.

[0014] Preferably, the connecting frame is L-shaped, and mounting holes are provided on both the left and right sides of the interior of the connecting frame, with 2-4 sets of mounting holes.

[0015] In summary, compared with the prior art, the present invention provides a load-bearing plate structure for metal roofing panel construction projects, which has the following beneficial effects: 1. This invention, through the addition of a first motor, can drive the rotation of a first lead screw, thereby driving the load-bearing plate to move up and down via a slider. Furthermore, a second motor can drive the rotation of a second lead screw, allowing the support plate to tilt via a transmission block and transmission arm. This enables workers to lean on the tilted support plate during construction of metal roof panels on sloping surfaces, reducing the risk of falls due to loss of balance. Since workers need to adopt different postures on the load-bearing plate surface during construction, such as bending, squatting, or standing, the tilted support plate can be adjusted according to their needs, allowing for more comfortable and natural construction postures, reducing fatigue and discomfort. The combination of the support plate and the load-bearing plate increases the overall integrity and stability of the structure. Under pressure, the support plate can share some of the load, reducing stress concentration on the load-bearing plate, thereby improving the overall load-bearing capacity of the structure and enhancing the practicality of the load-bearing plate. 2. By adding steel ropes and counterweights, this invention provides additional tensile constraints on the outer side of the load-bearing plate and the extension plate. This constraint can limit the lateral deformation or displacement of the load-bearing plate when it is under load, thereby improving the stability of the load-bearing plate during use, avoiding the problem of bending and breaking of the load-bearing plate, and improving the safety of the load-bearing plate during use.

[0024] 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.

[0025] This invention provides a technical solution: a load-bearing plate structure for metal roof panel construction, comprising an assembly plate 1, a connecting frame 2, a through groove 3, a first motor 4, a guide rod 5, a first lead screw 6, a slider 7, a load-bearing plate 8, an extension plate 9, a hinge seat 10, a support plate 11, a second motor 12, a second lead screw 13, a transmission block 14, a hinge block 15, a transmission arm 16, a connecting column 17, a steel rope 18, a roller 19, a counterweight 20, a slide groove 21, a mating plate 22, a locking block 23, an assembly cylinder 24, an insert rod 25, a through hole 26, a spring 27, a limiting pin 28, an extension support plate 29, and a reinforcing rib 30. Please see Figure 1The mounting plate 1 has connecting brackets 2 installed on both the upper and lower sides of its back. Each connecting bracket 2 has 2-4 sets of mounting holes on both the left and right sides of its interior. The connecting brackets 2 are L-shaped and play a crucial role in connecting and supporting the upper and lower sides of the mounting plate 1. The connecting brackets 2 are made of high-strength metal, which has excellent compressive strength and corrosion resistance, ensuring that they will not easily deform or be damaged during long-term use. The L-shaped design of the connecting brackets 2 makes the connection between the mounting plate 1 and other structures more stable, and the L-shape better disperses stress. The 2-4 sets of mounting holes on both the left and right sides of the connecting brackets 2 allow for the use of various standard bolts or connectors, facilitating connection with other components and providing convenience for future maintenance or modification. This design allows the mounting plate 1 to be flexibly combined with other structures. For example, in metal roofing panel construction projects, it can be tightly connected to the supporting frame to ensure the stability of the entire structure. This connection method also has a certain vibration damping effect. When subjected to external vibrations, the connecting frame 2 can effectively absorb and disperse vibration energy through its own structural characteristics and its connection with other components, reducing the impact on the entire structure and thus extending the service life of the structure. Please refer to [link / reference]. Figure 2 The assembly plate 1 has through slots 3 in the middle and on both sides. The first motor 4 is inserted into the lower part of the assembly plate 1, and the top of the rotor of the first motor 4 passes through the interior of the middle through slot 3. The opening of the through slot 3 can optimize the space utilization inside the assembly plate 1 and provide the necessary space for the installation and movement of other components. The inner wall of the through slot 3 is finely polished and has a smooth surface, which can reduce the friction of other components when they move in it, reduce the wear of components, and improve the operating efficiency of the entire structure. Please see Figure 3 The first lead screw 6 is coaxially connected to the top of the rotor of the first motor 4. Guide rods 5 are inserted into the through slots 3 on both the left and right sides. Slider 7 is sleeved on the outside of both the guide rods 5 and the first lead screw 6. (See also...) Figure 2Each slider 7 has a load-bearing plate 8 welded to its front side. The top of the first lead screw 6 is connected to the corresponding position of the top of the inner cavity of the through groove 3 via a ball bearing. Reinforcing ribs 30 are welded to the upper and lower ends of the load-bearing plate 8 at the connection points with the left and right sliders 7. The reinforcing ribs 30 improve the strength of the connection between the load-bearing plate 8 and the slider 7. The reinforcing ribs 30 adopt a triangular structure, which is one of the most mechanically stable shapes and can effectively distribute stress over a larger area. The material of the reinforcing ribs 30 is the same as that of the load-bearing plate 8, and welding technology is used during the welding process to ensure welding quality, making the reinforcing ribs 30, the load-bearing plate 8, and the slider 7 form a whole. This improves the shear resistance and load-bearing capacity of the connection point, thus ensuring that the load-bearing plate 8 will not break or deform at the connection point with the slider 7 when subjected to large loads. The upper surface of the load-bearing plate 8 is covered with anti-slip rubber. The anti-slip rubber provides good anti-slip performance for personnel working on the load-bearing plate 8 and for equipment placed on it. Furthermore, the surface of the anti-slip rubber has a special texture that increases friction, preventing personnel from slipping or equipment from sliding. The anti-slip rubber also has a certain degree of elasticity, which can buffer the impact of heavy objects on the load-bearing plate 8 to a certain extent and protect the surface of the load-bearing plate 8 from damage. At the same time, the anti-slip rubber is made of materials with good weather resistance, which can maintain its anti-slip performance under different ambient temperature and humidity conditions and extend its service life. Please see Figure 4 Expansion plate 9 is installed at the front end of load-bearing plate 8. Please refer to [link / reference]. Figure 5 The front side of the extension plate 9 is equipped with a second motor 12 via a bracket. The left and right sides of the rear of the extension plate 9 are equipped with hinge seats 10. The inner side of the hinge seats 10 is hinged with a support plate 11 via a bearing. The outer end of the rotor of the second motor 12 is coaxially connected to a second lead screw 13. The transmission block 14 is screwed onto the outside of the second lead screw 13. (See attached image.) Figure 6 Transmission arms 16 are hinged to both the left and right sides of the transmission block 14. The hinges between the transmission arms 16 and the transmission block 14 utilize high-strength pins, which are hardened to provide high hardness and wear resistance. This hinge design allows the transmission arms 16 to rotate flexibly under the influence of the transmission block 14 while ensuring a secure connection. The length and shape of the transmission arms 16 are optimized to effectively transmit power to the support plate 11 during the movement of the transmission block 14, and the direction of force transmission can be adjusted according to the rotational requirements of the support plate 11. Please refer to [link to relevant documentation]. Figure 5 The top inner side of the transmission arm 16 is equipped with hinge blocks 15 via bearings. Please refer to [link / reference]. Figure 4 Connecting posts 17 are installed on both the left and right sides of the front part of the expansion plate 9. Steel cables 18 are connected to the outside of the connecting posts 17. Please refer to [link / reference]. Figure 1The outer ends of the steel rope 18 pass through the upper left and right sides of the assembly plate 1, and counterweights 20 are installed at the outer ends of the steel rope 18. A groove 21 is opened in the middle of the top of the extension plate 9. A locking block 23 is inserted into the groove 21. The top of the locking block 23 is connected to the bottom of the transmission block 14 at the corresponding position. The rear end of the second lead screw 13 is equipped with a mating plate 22 through a ball bearing. The bottom end of the mating plate 22 is connected to the upper surface of the extension plate 9 at the corresponding position. The groove 21 provides precise guidance for the movement of the locking block 23. The inner wall of the groove 21 is smooth, and its dimensional accuracy ensures that the locking block 23 moves smoothly and accurately within it. The depth and width of the groove 21 are designed according to the size of the locking block 23, and there is an appropriate gap between them. This ensures the free movement of the locking block 23 and prevents the locking block 23 from shaking or dislodging from the groove 21 during movement. The ball bearing between the second lead screw 13 and the mating plate 22 plays a role in reducing friction and providing precise axial positioning. The ball bearing has a precise internal structure, ensuring minimal friction between the second lead screw 13 and the mating plate 22 during rotation, thus improving the overall operating efficiency. The bottom end of the mating plate 22 connects to the corresponding position on the upper surface of the extension plate 9. The mating plate 22 provides rear-end support for the second lead screw 13, preventing axial movement during rotation and improving its stability. The top of the hinge block 15 connects to the corresponding position on the bottom of the support plate 11. Both the assembly plate 1 and the steel rope 18 have hollow penetrations. Rollers 19 are inserted into the cavities of the assembly plate 1 via rotating shafts, and the steel rope 18 is secured inside each roller 19. The steel rope 18 is made of high-strength steel wire rope, with internal wires processed using a special twisting technique, resulting in high tensile strength. The hollow structure of the assembly plate 1 provides a smooth passage for the steel rope 18 as it passes through the upper left and right sides of the assembly plate 1. Meanwhile, rollers 19 are inserted into the cavities of the assembly plate 1 via rotating shafts, and steel ropes 18 are all secured inside the rollers 19. The rollers 19 greatly reduce the friction of the steel ropes 18 during the passage process, extending the service life of the steel ropes 18, and ensuring that the steel ropes 18 can move flexibly under tension without jamming. The weight of the counterweight 20 is precisely calculated to provide appropriate tensile constraints for the entire structure. The counterweight 20 is made of high-density metal materials, such as cast iron or lead alloy, which can achieve a large weight in a small volume. The shape of the counterweight 20 is designed for easy installation on the outer end of the steel rope 18, and the connection between it and the steel rope 18 is reinforced to ensure a firm connection and prevent the counterweight 20 from falling off during use. The presence of the counterweight 20 can limit the lateral deformation or displacement of the load-bearing plate 8 and the extension plate 9 under load, improving the stability of the load-bearing plate 8 and the extension plate 9 during use, avoiding the problem of bending and breaking of the load-bearing plate 8, and improving the safety of the entire structure. A flexible pad is laid on top of the support plate 11, providing a more comfortable support experience for construction workers. The flexible pad is made of soft, elastic materials, such as rubber or foam. This material can deform to a certain extent according to the shape of the construction worker's body, better conforming to the curves of the human body, reducing pressure points when leaning against it, and reducing fatigue. At the same time, the flexible pad has good breathability, allowing air to circulate within it, preventing stuffiness caused by prolonged leaning. The flexible pad also has a certain degree of anti-slip property, preventing slippage during leaning. Ventilation holes are provided inside the support plate 11, which helps improve its comfort and practicality. These ventilation holes allow air to circulate within the support plate 11, allowing heat and moisture emitted by the body to dissipate when the construction worker leans against it, keeping the surface of the support plate 11 dry and comfortable. Furthermore, the ventilation holes can also reduce the weight of the support plate 11 to some extent, improving its portability and ease of installation. Please refer to [link to relevant documentation]. Figure 6 and Figure 7 An assembly cylinder 24 is connected to the left side of the support plate 11. An insert rod 25 is inserted inside the assembly cylinder 24. Both the assembly cylinder 24 and the insert rod 25 have through holes 26 inside. The number of through holes 26 inside the assembly cylinder 24 is 3-6 sets. A spring 27 is connected to the bottom of the inner cavity of the through hole 26 inside the insert rod 25. A limit pin 28 is installed at the outer end of the spring 27, and the front end of the limit pin 28 penetrates the interior of the through hole 26. An extension plate 29 is connected to the outer end of the insert rod 25. The length of the extension plate 29 is the same as the length of the support plate 11. The top of the extension plate 29 is arc-shaped. The connection between the extension plate 29 and the insert rod 25 is firm, using welding or threaded connection methods. The extension plate 29 increases the support area of ​​the support plate 11. When a larger support range is needed, the extension plate 29 can be pulled out. The length of the extension plate 29 is the same as the length of the support plate 11. This design ensures that the overall aesthetics and coordination are maintained when expanding the support area. The top of the extended pallet 29 is curved. The curved top design conforms to the ergonomic principle. When construction workers need to place tools or lean on the extended pallet 29, the curved surface can better fit the tools or the human body, preventing the tools from slipping and improving the comfort of the construction workers.

[0026] This design incorporates a first motor 4 to drive the rotation of a first lead screw 6, which in turn drives the up-and-down movement of the load-bearing plate 8 via a slider 7. Furthermore, a second motor 12 drives the rotation of a second lead screw 13, which in turn drives the tilting of the support plate 11 via a transmission block 14 and a transmission arm 16. This allows workers to lean on the tilted support plate 11 during construction on the metal roof panel, reducing the risk of falls due to loss of balance. Since workers need to assume various postures on the load-bearing plate 8 during construction, such as bending, squatting, or standing, the tilted support plate 11 can be adjusted to allow for more comfortable and natural postures, reducing fatigue and discomfort. The combination of the support plate 11 and the load-bearing plate 8 increases the overall integrity and stability of the structure. Under pressure, the support plate 11 can share some of the load, reducing stress concentration on the load-bearing plate 8 and thus improving the overall load-bearing capacity and practicality of the load-bearing plate 8.

[0027] This solution, through the addition of steel rope 18 and counterweight 20, provides additional tensile constraints on the outer side of the load-bearing plate 8 and extension plate 9. This constraint can limit the lateral deformation or displacement of the load-bearing plate 8 when it is under load, thereby improving the stability of the load-bearing plate 8 during use, avoiding the problem of bending and breaking of the load-bearing plate 8, and improving the safety of the load-bearing plate 8 during use.

[0028] Therefore, this design ensures that the coordination between the first motor 4, the first lead screw 6, the slider 7, and the load-bearing plate 8 guarantees stable and efficient conversion of the motor's rotational motion into linear motion during rotation. The slider 7 is fitted over the first lead screw 6 and the guide rod 5. The guide rod 5 plays a crucial guiding role in this process, acting like a track to ensure that the slider 7 moves only in the predetermined direction. The fit between the slider 7, the first lead screw 6, and the guide rod 5 is extremely precise. The internal structure of the slider 7 allows it to tightly engage with the threads of the first lead screw 6 while sliding smoothly on the guide rod 5, enabling the slider 7 to move precisely up and down under the rotation of the first lead screw 6. The front side of the slider 7 is welded to the load-bearing plate 8. The load-bearing plate 8 is a crucial load-bearing component in the entire structure, ensuring a firm and reliable connection between the slider 7 and the load-bearing plate 8. When the slider 7 moves up and down, it drives the load-bearing plate 8 to move up and down as well. This up-and-down movement function is of great significance in the construction of metal roof panels. For example, at construction locations at different heights, the height of the support plate 8 can be adjusted to allow construction workers to more easily reach the appropriate working height, improving the flexibility and convenience of construction. Next, let's examine the relationship between the second motor 12, the second lead screw 13, the transmission block 14, the transmission arm 16, and the support plate 11. The second motor 12 is also a high-performance power device, driving the second lead screw 13 to rotate. The second lead screw 13 is coaxially connected to the outer end of the rotor of the second motor 12, ensuring efficient and accurate power transmission. The transmission block 14 is screwed onto the outside of the second lead screw 13, with its internal threads tightly engaging with the threads of the second lead screw 13. Transmission arms 16 are hinged to the left and right sides of the outer side of the transmission block 14, allowing the transmission arms 16 to rotate flexibly within a certain range. A hinge block 15 is mounted on the inner top of the transmission arm 16 via a bearing, and the hinge block 15 is connected to the bottom of the support plate 11. When the second motor 12 drives the second lead screw 13 to rotate, the transmission block 14 moves linearly along the thread of the second lead screw 13, thereby driving the transmission arm 16 to move, ultimately achieving the tilting of the support plate 11. In metal roof panel construction, especially in sloping scenarios, the tilting function of the support plate 11 has an undeniable advantage. When working on a slope, it is difficult for construction workers to maintain their balance, and they are prone to falling, posing a significant safety hazard. The tilting support plate 11 in this solution provides a reliable support point for construction workers. Workers can lean against the support plate 11, using its support to maintain their balance, thus greatly reducing the risk of falling. Furthermore, construction workers need to adopt different postures on the surface of the load-bearing plate 8 during construction, such as bending over, squatting, or standing. Since the support plate 11 can be tilted according to the needs of the construction workers, they can adjust the support plate 11 to the most suitable angle based on their current work, allowing them to work in a more comfortable and natural posture.This ergonomic design effectively reduces fatigue and discomfort for construction workers. Maintaining an uncomfortable posture for extended periods can exacerbate physical fatigue, impacting construction efficiency and quality. Simultaneously, the combination of the support plate 11 and the load-bearing plate 8 contributes positively to the overall integrity and stability of the structure. The connection between the support plate 11 and the load-bearing plate 8 is carefully designed to ensure they work collaboratively under pressure. When external loads act on the entire structure, the support plate 11 can share a portion of the load, preventing stress concentration on the load-bearing plate 8. For example, when bearing large roof loads or temporary loads during construction, the support plate 11 acts as an auxiliary support, distributing some of the load. This not only reduces the burden on the load-bearing plate 8 but also improves the overall load-bearing capacity of the structure, significantly enhancing the practicality of the load-bearing plate 8. Furthermore, the steel rope 18 and counterweight 20 in this design also play crucial roles. The steel rope 18 uses high-strength steel wire rope, with its internal steel wires undergoing a special twisting process, resulting in extremely high tensile strength. The counterweight 20 is made of high-density metal materials, such as cast iron or lead alloy, to ensure a large weight in a small volume. One end of the steel rope 18 is connected to the connecting post 17 of the extension plate 9, and the other end passes through the upper left and right sides of the assembly plate 1 and connects to the counterweight 20. This connection method allows the steel rope 18 and the counterweight 20 to provide additional tensile restraint to the outer side of the load-bearing plate 8 and the extension plate 9. When the load-bearing plate 8 is under load, especially under lateral load, lateral deformation or displacement problems are prone to occur. The tensile restraint of the steel rope 18 and the counterweight 20 is like an invisible hand, tightly holding the load-bearing plate 8 and the extension plate 9, restricting their lateral movement. This restraint is crucial for improving the stability of the load-bearing plate 8 during use. If the load-bearing plate 8 undergoes lateral deformation or displacement, it may lead to an imbalance of forces in the entire structure, resulting in a series of safety problems, such as bending and breaking of the load-bearing plate 8. The tension restraint provided by steel cable 18 and counterweight 20 effectively prevents these problems from occurring, greatly improving the safety of the load-bearing plate 8 during use. This is crucial for the long-term stable use of metal roofing panels and for ensuring the safety of construction workers.
