Description

Technical Field

[0001] This utility model relates to the field of beam lap joint technology, and in particular to a building beam lap joint structure. Background Technology

[0002] A lap joint structure for building beams refers to a construction method used to connect main beams and secondary beams in a building. Lap joints ensure the stability of the building under gravity loads and external forces, distribute the load, and improve the overall strength and stability of the structure. This structural design typically involves considerations such as lap length, connectors, and welding or bolting connections to ensure that the lap joint has sufficient load-bearing capacity and stiffness.

[0003] In existing technologies, lap joints are commonly used to connect building beams. However, many lap joints fail to provide sufficient support when connecting and fixing beams, resulting in the inability to effectively distribute the load. This may cause stress concentration in the lap area, increasing the risk of beam damage or deformation. Long-term exposure to uneven or excessive loads may lead to fatigue damage at the beam connection points, thereby shortening the service life of the beam.

[0004] Therefore, those skilled in the art have provided a building beam lap structure to solve the problems mentioned in the background art. Utility Model Content

[0005] The purpose of this utility model is to address the shortcomings of existing technologies by proposing a building beam lap joint structure. During use, this structure, through its arched support frame, effectively disperses and transfers loads, reducing stress concentration and thus providing greater stability when the beam bears gravity and other external forces. Simultaneously, the connecting plate and upper limiting plate further enhance the rigidity and strength of the connection area, preventing beam deformation under stress and allowing the beam to maintain its original shape. This ensures the overall stability of the building and prevents structural problems caused by beam deformation, thereby effectively extending the building's service life.

[0006] To achieve the above objectives, the present invention provides the following technical solution:

[0007] A building beam lap structure includes a frame, with connecting plates fixedly connected to both ends of the frame, and limiting plates fixedly connected to one side of one end of multiple connecting plates. Arched support frames are fixedly connected to the upper and lower ends of the frame, and threaded posts are threadedly connected to the four corners of the middle of two arched support frames. Lifting rings are fixedly connected to one side of multiple threaded posts, and positioning pins are fitted inside the multiple lifting rings. Beam bodies are provided on both sides of the interior of the frame, and through holes are opened at both ends of one side of the upper and lower ends of the two beam bodies.

[0008] Through the above technical solution, the structure, with its arched support frame, can effectively distribute and transfer loads, reducing stress concentration and thus providing greater stability when the beam bears gravity and other external forces. At the same time, the connecting plate and upper limiting plate further enhance the rigidity and strength of the connection area, preventing the beam from deforming under stress. This allows the beam to maintain its original shape, ensuring the overall stability of the building and preventing structural problems caused by beam deformation, thereby effectively extending the service life of the building.

[0009] Furthermore, each of the aforementioned positioning pins has a pin on its inner side;

[0010] Through the above technical solution, the pin can further fix the position of the positioning pin, thereby enhancing the stability of the threaded post, preventing it from loosening due to vibration or external force, and effectively improving the safety and reliability of the structure.

[0011] Furthermore, one end face of each of the multiple threaded columns penetrates the interior of the through hole in the beam body;

[0012] Through the above technical solutions, the threaded column can be more firmly connected to the beam body, ensuring that it will not slip or fall off during use, thereby improving the load-bearing capacity and safety performance of the entire structure.

[0013] Furthermore, both sides of one end face of the two bow-shaped support frames are at a 30-degree angle to the crossbeam body;

[0014] Through the above technical solution, the bow-shaped support frame forms a 30-degree angle with the crossbeam body, which enables the bow-shaped support frame to more stably distribute and bear forces from all directions, effectively improving the overall structure's seismic and compressive resistance.

[0015] Furthermore, the outer walls of all of the aforementioned limiting plates are tightly fitted to the crossbeam body;

[0016] Through the above technical solution, the limiting plate is closely fitted to the crossbeam body, which can effectively prevent the crossbeam body from shifting or deviating, thereby ensuring the overall stability and safety of the structure and extending its service life.

[0017] Furthermore, the inner wall of the frame is tightly fitted to the outer wall of the beam body;

[0018] Through the above technical solution, the frame and the beam body are closely fitted, ensuring a firm connection between the beam body and the frame, reducing the risk of loosening and swaying of the structure, thereby improving the overall strength and stability of the frame.

[0019] This utility model has the following beneficial effects:

[0020] 1. The present invention proposes a building beam lap joint structure. Compared with existing building beam lap joint structures, this building beam lap joint structure, through the setting of the bow-shaped support frame, can effectively disperse and transfer the load, reduce stress concentration, and thus provide greater stability when the beam bears gravity and other external forces. At the same time, the setting of the connecting plate and the upper limit plate further enhances the rigidity and strength of the connection area, preventing the beam from deforming under force, thereby enabling the beam to maintain its original shape, ensuring the overall stability of the building, preventing structural problems caused by beam deformation, and thus effectively extending the service life of the building.

[0021] 2. The building beam lap joint structure proposed in this utility model, compared with the existing building beam lap joint structure, has a threaded post that penetrates the inner beam body during use, and a positioning pin that penetrates the upper end of the threaded post to fix the lifting ring, so that the threaded post will not come out of the beam body due to vibration, thereby effectively avoiding accidents caused by the collapse of the beam body due to vibration, and improving the safety of the overall structure.

[0029] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of specific embodiments. Obviously, the described specific embodiments are only a part of the specific embodiments of the present invention, and not all of them. Based on the specific embodiments of the present invention, all other specific embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0030] Reference Figure 1-5 This utility model provides a specific embodiment: a building beam lap structure, including a frame 1, with connecting plates 4 fixedly connected to both ends of the frame 1, and limiting plates 5 fixedly connected to one end of each of the connecting plates 4. Arched support frames 2 are fixedly connected to the upper and lower ends of the frame 1, and threaded posts 6 are threadedly connected to the four corners of the middle of each of the two arched support frames 2. Lifting rings 7 are fixedly connected to one end of each of the threaded posts 6, and positioning pins 8 are fitted inside each of the lifting rings 7. Beam bodies 3 are provided on both sides inside the frame 1. Both ends of the upper and lower face are provided with through holes 10. When in use, the structure can effectively distribute and transfer the load through the set bow-shaped support frame 2, reduce stress concentration, and thus provide greater stability when the beam bears gravity and other external forces. At the same time, the set connecting plate 4 and upper limit plate further enhance the rigidity and strength of the connection area, prevent the beam from deforming when under force, so that the beam can maintain its original shape, ensure the overall stability of the building, and prevent structural problems caused by beam deformation, thereby effectively extending the service life of the building.

[0031] Each of the multiple locating pins 8 has a pin 9 on one side inside. The pin 9 can further fix the position of the locating pin 8, thereby enhancing the stability of the threaded post 6 and preventing it from loosening due to vibration or external force, effectively improving the safety and reliability of the structure. One end face of each of the multiple threaded posts 6 penetrates the interior of the through hole 10 of the crossbeam body 3, allowing the threaded posts 6 to be more firmly connected to the crossbeam body 3, ensuring that they will not slip or fall off during use, thereby improving the load-bearing capacity and safety performance of the entire structure. Both sides of one end face of the two bow-shaped support frames 2 are at a 30-degree angle to the crossbeam body 3, forming a 30-degree angle between the bow-shaped support frame 2 and the crossbeam body 3. This allows the bow-shaped support frame 2 to more stably distribute and bear forces from all directions, effectively improving the overall structure's seismic and compressive resistance. The outer walls of multiple limiting plates 5 are tightly fitted to the crossbeam body 3. The tight fit between the limiting plates 5 and the crossbeam body 3 effectively prevents the crossbeam body 3 from shifting or deviating, thereby ensuring the overall stability and safety of the structure and extending its service life. The inner wall of the frame 1 is tightly fitted to the outer wall of the crossbeam body 3, ensuring a firm connection between the crossbeam body 3 and the frame 1, reducing the risk of loosening and swaying of the structure, and thus improving the overall strength and stability of the frame 1.

[0032] Working Principle: During use, workers place the two ends of the crossbeam body 3 into the frame 1, thread the bolt column into the arched support frame 2, and pass one end of the bolt column through the crossbeam body 3. After the bolt column is in place, workers insert the positioning pin 8 through the lifting ring 7 fixed to the upper end of the threaded column 6, and insert a pin 9 into one end of the positioning pin 8 to prevent the threaded column 6 from detaching from the crossbeam body 3 due to vibration. This effectively avoids accidents caused by the collapse of the crossbeam body 3 due to vibration, improving the overall structural safety. Simultaneously, the arched support frame 2 at the upper end of the frame 1 effectively disperses and transfers the load, reducing stress concentration and providing greater stability when the crossbeam bears gravity and other external forces. Furthermore, the connecting plate 4 and limiting plate 5 at the upper end of the frame 1 further enhance the rigidity and strength of the connection area, preventing deformation of the crossbeam under stress. This allows the crossbeam to maintain its original shape, ensuring the overall stability of the building, preventing structural problems caused by crossbeam deformation, and effectively extending the building's service life.
