Description

Technical Field

[0001] This utility model relates to the field of building component technology, and in particular to a BIM-based prefabricated building component structure. Background Technology

[0002] BIM-based prefabricated building component structures are an advanced building structure system that combines Building Information Modeling (BIM) technology with prefabricated building components. In this structure, BIM technology is used for 3D modeling to accurately design various prefabricated building components. The size, shape, and connection method of the components are planned and optimized in detail. Through the BIM model, the production, transportation, and assembly process of the components can be simulated, and potential problems can be identified and solved in advance. This improves the quality and efficiency of building projects, reduces resource waste and environmental pollution, and promotes the development of the construction industry towards industrialization and informatization.

[0003] A search revealed Chinese Patent Publication No. CN215759604U, which discloses a BIM-based prefabricated building component structure and its usage method. The structure includes a first panel and a second panel, with the first panel located in front of the second panel. A first splicing block is provided on the rear side of the first panel, and a second splicing block adapted to the first splicing block is provided on the front side of the second panel. A first recessed receiving groove is formed on the front side of the second panel. This utility model relates to the field of prefabricated building technology. This BIM-based prefabricated building component structure allows for easy disassembly. When disassembly is required, manual operation involves pulling a sliding rack plate, which rotates a gear roller, pulling the rack plate into the first receiving groove. This allows for manual removal of the second splicing block from the first splicing block, eliminating the need for forced disassembly, thus improving panel protection, reducing panel waste during construction, and facilitating manual disassembly of assembled panels. However, during component assembly, manual alignment of the first and second panels is required, leading to low installation efficiency and a high risk of errors. Utility Model Content

[0004] To overcome the above shortcomings, this utility model provides a BIM-based prefabricated building component structure, which aims to improve the problem in the existing technology that requires manual alignment of the first and second plates during component docking, resulting in low installation efficiency and easy errors.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: a BIM-based prefabricated building component structure, comprising a support plate, an installation plate one fixedly connected to the top rear side of the support plate, an installation plate two slidably connected to the top left side of the support plate, an inner guide plate fixedly connected to the top of the support plate, an outer guide plate fixedly connected to the top of the support plate, a rear plate fixedly connected to the rear side of the outer wall of the outer guide plate, multiple guide grooves provided on the front side of the outer wall of the installation plate one, multiple guide blocks fixedly connected to the rear side of the outer wall of the installation plate two, multiple transverse reinforcing ribs fixedly connected to the outer walls of both the installation plate one and the installation plate two, multiple vertical reinforcing ribs fixedly connected to the outer walls of both the installation plate one and the installation plate two, and two locking mechanisms provided between adjacent installation plates one and two.

[0006] Through the above technical solution: the support plate provides stable support, the mounting plate one and the mounting plate two form the component docking surface, the inner guide plate, the outer guide plate and the rear plate form a guide and limit system, the guide groove and the guide block cooperate to achieve preliminary positioning, and the horizontal and vertical reinforcing ribs enhance the structural strength of the mounting plate.

[0007] As a further description of the above technical solution: The locking mechanism includes a slide block, the rear side of the outer wall of the slide block is fixedly connected to the front side of the inner wall of the mounting plate, a slide plate is slidably connected to the inner wall of the slide block, two locking plates are rotatably connected to the front side of the outer wall of the slide plate, a sleeve rod is rotatably connected to the rear side of the outer wall of each of the two locking plates, a spring is rotatably connected to the rear side of the outer wall of each of the two locking plates, a screw is threadedly connected to the inner wall of the slide plate, and a throttle is fixedly connected to the rear end of the screw.

[0008] The above technical solution provides a sliding track for the skateboard. The locking plate, sleeve rod, and spring work together to achieve automatic initial locking. The screw and throttle make it easy for the operator to precisely control the movement of the skateboard, thereby enhancing the locking force. Compared with the traditional connection method, it reduces manual intervention, improves connection efficiency and reliability, ensures that mounting plate one and mounting plate two are firmly connected, and prevents components from loosening.

[0009] As a further description of the above technical solution: The outer walls of both the inner and outer guide plates are provided with multiple wheel holes, and the inner walls of each of the multiple wheel holes are fixedly connected to two wheel axles.

[0010] The above technical solution lays the foundation for the rolling auxiliary system. The wheel hole is used to install the wheel axle, which makes the subsequent installation and rotation of the roller possible. It can effectively reduce the friction when the second mounting plate slides, reduce the installation resistance, make the second mounting plate slide more smoothly in the guide system, improve the ease of operation during component docking, and improve the overall installation efficiency.

[0011] As a further description of the above technical solution: Rollers are rotatably connected to the outer walls of the multiple axles, and bases are fixedly connected to the bottoms of the inner guide plate and the outer guide plate.

[0012] Through the above technical solution, the roller and the axle cooperate to form a rolling structure, which further reduces the friction of the sliding of the mounting plate, making the component docking easier and more efficient. The base firmly installs the inner guide plate and the outer guide plate on the support plate, which enhances the stability of the guiding system, ensures that the guiding structure will not be displaced during the component installation process, guarantees the guiding accuracy, and provides a reliable guarantee for accurate component docking.

[0013] As a further description of the above technical solution: The inner walls of both bases are slidably connected with two positioning pins, and the top of the support plate is provided with multiple positioning holes.

[0014] The above technical solution achieves precise positioning and secure fixing of the inner and outer guide plates. The positioning pins are inserted into the positioning holes to ensure accurate positioning between the base and the support plate, preventing the guide plates from shifting or shaking during use, ensuring the stability and reliability of the guiding system, and thus providing a stable guiding foundation for the precise docking of components, further improving the installation quality of prefabricated building components.

[0015] As a further description of the above technical solution: The outer wall of the inner guide plate is fixedly connected with multiple reinforcing strips, and the outer wall of the screw is fixedly connected with a limit block.

[0016] The above technical solutions improve the reliability and safety of the structure. The reinforcing strip enhances the structural strength of the inner guide plate, making it less prone to deformation under the external force when the components are joined, thus ensuring its continuous and stable guiding function. The limiting block restricts the rotation stroke of the screw, preventing the screw from rotating excessively and causing the slide plate to exceed its normal working range. This also avoids damage to the locking mechanism due to improper operation, ensuring the safe and stable operation of the locking mechanism and guaranteeing reliable component connection.

[0017] As a further description of the above technical solution: The inner wall of the first mounting plate has two limiting grooves, and the rear side of the outer wall of the second mounting plate has two inserts fixedly connected.

[0018] The above technical solution optimizes the component docking and locking process. The limiting groove and the limiting block cooperate to limit the position of the screw. During the installation process, the insert block contacts the locking plate and pushes it to rotate, triggering the locking mechanism. This makes the docking and locking process of mounting plate one and mounting plate two more precise and orderly, improving the stability and reliability of the component connection.

[0019] As a further description of the above technical solution: Two locking grooves are provided on the rear side of the outer wall of the second mounting plate, and two baffles are fixedly connected to the front side of the outer wall of the slide plate.

[0020] The above technical solution ensures the effective operation of the locking mechanism. The lock groove and the lock plate cooperate to achieve the positioning connection and final locking of mounting plate one and mounting plate two. The baffle prevents the lock plate from rotating excessively, keeping it at a vertical angle and accurately falling into the lock groove. This ensures the accuracy and stability of the locking action of the locking mechanism, prevents the component connection from being unstable due to improper rotation angle of the lock plate, and further improves the reliability of the connection of prefabricated building components.

[0021] This utility model has the following beneficial effects: 1. In this utility model, the inner guide plate and the outer guide plate are fixed to the top of the support plate to form a guiding system, which provides clear guidance during the installation of components and enables more accurate docking. At the same time, the guide groove and the guide block cooperate with each other to enable adjacent components to be accurately positioned, reducing the amount of manual adjustment and improving docking efficiency.

[0022] 2. In this utility model, the spring releases its elastic force instantly to push the locking plate to rotate forward, so that the locking plate can quickly fall into the locking groove, initially realizing the positioning connection of mounting plate one and mounting plate two. Then, the throttle is turned to drive the screw to rotate, so that the slide plate moves backward in the slide block, thereby driving the locking plate to apply greater pressure to mounting plate two, locking mounting plate one and mounting plate two together, preventing the components from loosening or shifting during use.

Detailed Implementation

[0025] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0026] See attached document Figure 2 Appendix Figure 3 and attached Figure 4This utility model provides an embodiment of a BIM-based prefabricated building component structure, including a support plate 1, which serves as a basic load-bearing component, providing a stable support platform for the entire structure and ensuring stability during component installation and use. An installation plate 3 is fixedly connected to the top rear side of the support plate 1, providing a base surface for component installation and facilitating connection with other components. An installation plate 4 is slidably connected to the top left side of the support plate 1, allowing the installation plate 4 to move flexibly on the support plate 1 and achieve docking installation with the installation plate 3. An inner guide plate 5 is fixedly connected to the top of the support plate 1. Together with the outer guide plate 6, they form a guiding system, providing guidance for the sliding of the second mounting plate 4 and ensuring the accuracy of its movement. The top of the support plate 1 is fixedly connected to the outer guide plate 6, further enhancing the guiding function. At the same time, it works with the inner guide plate 5 to limit the movement range of the second mounting plate 4. The rear side of the outer wall of the outer guide plate 6 is fixedly connected to the rear plate 7, which serves to limit and protect the second mounting plate 4 from excessive sliding and to protect the guiding system. The front side of the outer wall of the first mounting plate 3 has multiple guide grooves 8, which cooperate with the guide blocks 9 on the second mounting plate 4 to achieve preliminary and accurate positioning of adjacent components. To reduce manual adjustment workload, multiple guide blocks 9 are fixedly connected to the rear side of the outer wall of mounting plate 2 4, corresponding to the guide groove 8. These blocks slide along the guide groove 8 during movement, ensuring accurate component alignment. Multiple transverse reinforcing ribs 10 are fixedly connected to the outer walls of both mounting plate 1 3 and mounting plate 2 4, enhancing the horizontal structural strength of the mounting plates and improving their resistance to lateral loads. Multiple vertical reinforcing ribs 11 are also fixedly connected to the outer walls of both mounting plate 1 3 and mounting plate 2 4, enhancing the vertical structural strength of the mounting plates and ensuring they can withstand larger vertical loads. The inner guide plate 5... Multiple wheel holes 12 are provided on the outer wall of both the outer guide plate 6 and the outer guide plate 6 for mounting wheel axles 13, providing a mounting base for the rotation of the roller 14. Two wheel axles 13 are fixedly connected to the inner wall of each of the multiple wheel holes 12, supporting the roller 14 and enabling it to rotate flexibly. Rollers 14 are rotatably connected to the outer wall of each of the multiple wheel axles 13. When the mounting plate 2 4 slides, the roller 14 rotates on the wheel axle 13, reducing the friction during the sliding process of the mounting plate 2 4, making the sliding of the mounting plate 2 4 smoother, and improving the convenience and efficiency of component docking. Two locking mechanisms 2 are provided between the adjacent mounting plate 1 3 and mounting plate 2 4. Specifically, the support plate 1 serves as the basic load-bearing component, providing support for the overall structure. The inner guide plate 5 and the outer guide plate 6 are fixed to the top of the support plate 1. Together with the rear plate 7 on the rear side of the outer guide plate 6, they form a guiding and limiting system. During installation, the mounting plate 2 4 is inserted between the two guide plates and pushed backward. The guide block 9 on the rear side of its outer wall slides along the guide groove 8 on the front side of the outer wall of the mounting plate 1 3, achieving preliminary and accurate positioning of the component. The transverse reinforcing ribs 10 and vertical reinforcing ribs 11 set on the mounting plate 1 3 and the mounting plate 2 4 enhance the structural strength and stability of the mounting plate, ensuring that the component can withstand the load during installation and use. The wheel holes 12 on the inner guide plate 5 and the outer guide plate 6 are fixed with wheel axles 13. The wheel axles 13 are rotatably connected to rollers 14, forming a rolling auxiliary system. When the mounting plate 2 4 slides, the rollers 14 rotate on the wheel axles 13, reducing sliding friction and making the mounting plate 2 4 slide more smoothly, further improving the component docking efficiency.

[0027] See attached document Figure 4 Appendix Figure 5 and attached Figure 6 The locking mechanism 2 includes a slide block 201. The rear side of the outer wall of the slide block 201 is fixedly connected to the front side of the inner wall of the mounting plate 3, providing a sliding track and mounting base for the slide plate 202, ensuring the stability of the sliding direction of the slide plate 202. The slide plate 202 is slidably connected to the inner wall of the slide block 201. By sliding within the slide block 201, the locking plate 203 is moved to complete the locking action. Two locking plates 203 are rotatably connected to the front side of the outer wall of the slide plate 202. The locking plates 203 can rotate around the connection point with the slide plate 202 to cooperate with the insert block 21 and locking groove 22 on the mounting plate 4, completing the locking and unlocking of the components. The rear side of the outer wall of each of the two locking plates 203 is rotatably connected to a sleeve rod 204. During the rotation of the locking plate 203, the sleeve rod 204 extends and retracts to limit the rotation angle of the locking plate 203, ensuring the accuracy of the locking plate 203's action. The rear side of the outer wall of each of the two locking plates 203 is rotatably connected to a spring 205. When the locking plate 203 is compressed and rotates... The slide plate 202 stores elastic potential energy, and when released, it pushes the locking plate 203 to reset, realizing the automatic locking function. The inner wall of the slide plate 202 is threaded with a screw 206. The rotation of the screw 206 drives the slide plate 202 to slide along the slide block 201, realizing precise adjustment of the position of the locking plate 203. The rear end of the screw 206 is fixedly connected with a handle 207, which allows the operator to manually rotate the screw 206 to control the movement of the slide plate 202 and the locking plate 203. The rear side of the outer wall of the second mounting plate 4 is fixedly connected with two inserts 21. During the installation process, they contact the locking plate 203 and push it to rotate, triggering the locking action. The rear side of the outer wall of the second mounting plate 4 has two locking grooves 22 for accommodating the locking plate 203. They cooperate with the locking plate 203 to lock the first mounting plate 3 and the second mounting plate 4. The front side of the outer wall of the slide plate 202 is fixedly connected with two baffles 23 to limit the forward rotation angle of the locking plate 203, ensuring that the locking plate 203 remains stable in the locked state and preventing loosening. Specifically, when the guide block 9 is inserted into the guide groove 8, the insert block 21 contacts the two locking plates 203. Under the pressure of the insert block 21, the locking plate 203 rotates backward against the inner wall of the insert block 21. At this time, the sleeve rod 204 retracts and the spring 205 is compressed. When the guide block 9 is fully inserted into the guide groove 8, the locking plate 203 reaches the locking groove 22. The spring 205 releases its elastic force instantly, and the locking plate 203 rotates forward. Due to the blocking effect of the baffle 23, the locking plate 203 maintains a vertical angle. Then, the throttle 207 is turned, and the screw 206 drives the slide plate 202 to move backward in the slide block 201. At the same time, the rear outer wall of the locking plate 203 is pressed against the rear inner wall of the second mounting plate 4, thereby locking the first mounting plate 3 and the second mounting plate 4 together.

[0028] See attached document Figure 1 Appendix Figure 3 and attached Figure 5 Both the inner guide plate 5 and the outer guide plate 6 have bases 15 fixedly connected to their bottoms. The bases 15 securely mount the inner guide plate 5 and outer guide plate 6 to the top of the support plate 1, providing a stable support foundation for the guiding system and enhancing the overall stability of the guiding structure. Two positioning pins 16 are slidably connected to the inner walls of both bases 15. These positioning pins 16 can slide along the inner walls of the bases 15 and, by inserting into the positioning holes 17 on the top of the support plate 1, achieve precise positioning and fixation between the bases 15 and the support plate 1, preventing displacement of the inner guide plate 5 and outer guide plate 6 during use. The top of the support plate 1 has multiple positioning holes 17, which cooperate with the positioning pins 16 to provide a positioning reference for the installation of the inner guide plate 5 and outer guide plate 6, ensuring the accuracy of the guiding system's installation position. To ensure the accuracy of component docking guidance, the outer wall of the inner guide plate 5 is fixedly connected with multiple reinforcing strips 18. The reinforcing strips 18 enhance the structural strength and rigidity of the inner guide plate 5, improve the inner guide plate 5's ability to resist external deformation, and keep the inner guide plate 5 stable during component docking, so as to continuously play a guiding role. The outer wall of the screw 206 is fixedly connected with a limiting block 19. The limiting block 19 restricts the displacement of the screw 206 and prevents the screw 206 from changing its position during rotation. The inner wall of the mounting plate 1 3 has two limiting grooves 20. The limiting grooves 20 cooperate with the sliding plate 202 to limit the sliding range of the sliding plate 202 in the sliding seat 201, ensuring that the locking plate 203 is locked and unlocked in the correct position, so that the connection between the mounting plate 1 3 and the mounting plate 2 4 is reliable and stable. Specifically, the base 15 and the support plate 1 cooperate through the positioning pin 16 and the positioning hole 17 to achieve the stable installation and positioning of the inner guide plate 5 and the outer guide plate 6, ensuring the accurate installation of the guiding system, providing a reliable guiding benchmark for component docking, preventing the guide plate from shifting during use, and improving docking accuracy. The reinforcing strip 18 enhances the structural strength of the inner guide plate 5, enabling it to stably perform its guiding function during docking. The limiting block 19 restricts the displacement of the screw 206, ensuring the stability of the screw 206's position when rotating. Together with the limiting groove 20 and the sliding plate 202, it ensures that the locking plate 203 is locked and unlocked in the correct position, making the connection between the first mounting plate 3 and the second mounting plate 4 firm and reliable, avoiding connection failure caused by component displacement or operational deviation, and comprehensively improving the stability, reliability, and installation efficiency of the prefabricated building component structure.

[0029] Working principle: First, the support plate 1 serves as the basic load-bearing component, providing a stable support platform for the entire structure. The inner guide plate 5 and the outer guide plate 6 are fixed to the top of the support plate 1, together forming the guiding system. The rear plate 7 on the rear side of the outer wall of the outer guide plate 6 provides certain limiting and protection functions. The guide groove 8 on the front side of the outer wall of mounting plate one 3 cooperates with the guide block 9 on the rear side of the outer wall of mounting plate two 4. During installation, mounting plate two 4 is inserted between the inner guide plate 5 and the outer guide plate 6, and then mounted plate two 4 is pushed backward. The position and shape of the guide block 9 correspond to the guide groove 8. During the pushing process, the guide block 9 moves along the guide groove 8, realizing the initial precision of adjacent components. Precise positioning reduces the workload of manual position adjustment and improves docking efficiency. The horizontal reinforcing ribs 10 and vertical reinforcing ribs 11 on mounting plate 1 3 and mounting plate 2 4 enhance the structural strength and stability of the mounting plates, ensuring that the mounting plates can withstand large loads without easily deforming or being damaged during component installation and use. The wheel holes 12, wheel axles 13 and rollers 14 on the inner guide plate 5 and outer guide plate 6 form a rolling auxiliary system. When mounting plate 2 4 slides, the rollers 14 rotate on the wheel axles 13, reducing the friction during the sliding process of mounting plate 2 4, making the sliding of mounting plate 2 4 smoother and easier, and further improving the convenience and efficiency of component docking. Furthermore, the slide block 201 is fixed to the front side of the inner wall of the mounting plate 3, providing a sliding track for the slide plate 202 and limiting its direction of movement. The slide plate 202 can slide flexibly within the slide block 201. The two locking plates 203 are rotatably connected to the front side of the outer wall of the slide plate 202. When the guide block 9 is inserted into the guide groove 8, the insert block 21 on the mounting plate 4 contacts the locking plate 203. Under the pressure of the insert block 21, the locking plate 203 rotates backward around the rotation point of the slide plate 202, closely adhering to the inner wall of the insert block 21. At this time, the sleeve rod 204 rotatably connected to the locking plate 203 contracts, and the spring 205 is compressed. The spring 205 stores elastic potential energy during this process, accumulating force for the subsequent locking action. When the guide block 9 is fully inserted into the guide groove 8, the locking plate 203 reaches the locking groove 22 position on the mounting plate 4, and the spring 205 instantly releases its elastic force. The locking plate 203 is pushed forward to rotate. The baffle 23 on the front side of the outer wall of the sliding plate 202 prevents the locking plate 203 from rotating excessively, keeping it at a vertical angle and ensuring that the locking plate 203 falls accurately into the locking groove 22. This initially achieves the positioning and connection of the mounting plate 1 3 and the mounting plate 2 4. Subsequently, the operator turns the handle 207, which drives the screw 206 to rotate. Since the sliding plate 202 is threadedly connected to the screw 206, the rotation of the screw 206 is converted into the sliding plate 202 moving backward in the slide block 201. During the movement of the sliding plate 202, the rear outer wall of the locking plate 203 is in close contact with the rear inner wall of the mounting plate 2 4. As the sliding plate 202 continues to move backward, the locking plate 203 applies greater pressure to the mounting plate 2 4, firmly locking the mounting plate 1 3 and the mounting plate 2 4 together and preventing the components from loosening or shifting during use.
