Description

Technical Field

[0001] This utility model relates to the field of steel beam structure technology, specifically a novel high-strength, fatigue-resistant steel beam structure. Background Technology

[0002] Steel beam structures are a widely used load-bearing component in building engineering. They are typically made of steel and are used to support horizontal or inclined loads on buildings or bridges. Thanks to steel's high strength, lightweight, plasticity, and durability, steel beams have become an indispensable part of modern engineering, especially suitable for large-span, high-rise buildings and complex structures.

[0003] Bolting is a common connection method in the manufacturing and installation of steel beam structures, but this process can damage the anti-rust layer on the steel beam surface. During bolting, especially when tightening bolts with a wrench, the tightening force can cause friction or scratches on the steel beam surface, leading to damage to the anti-rust layer. This damage exposes the steel beam connection to air and moisture, causing rusting. Rusting leads to corrosion of the metal on the steel beam surface, forming oxides. This not only affects the appearance and durability of the steel beam but also reduces the strength of the connection, potentially leading to fatigue failure of the structure. First, rust is a product of oxidation on the steel surface, typically manifesting as rust (iron oxide). Rust causes a loss of mass in the metal on the steel beam surface, weakening areas of the originally robust beam. As corrosion continues, the cross-section of the steel beam gradually decreases, reducing its load-bearing capacity. Second, rust can also form irregular corrosion pits and cracks on the steel beam surface. These localized damages can cause stress concentration, increasing the material's susceptibility. Stress concentration makes steel beams more prone to cracking or fracture under stress, especially under long-term loads, which reduces the fatigue performance of the structure.

[0004] In view of this, we propose a new type of high-strength, fatigue-resistant steel beam structure. Utility Model Content

[0005] The purpose of this utility model is to provide a new type of high-strength, fatigue-resistant steel beam structure. This new type of high-strength, fatigue-resistant steel beam structure solves the problem that the strength and load-bearing capacity of the steel beam are affected after the anti-rust layer is damaged by bolt connections during the manufacturing and installation process.

[0006] To achieve the above objectives, this utility model provides the following technical solution:

[0007] A novel high-strength, fatigue-resistant steel beam structure includes a steel beam with a connecting mechanism. The connecting mechanism includes: a receiving frame; a hollow frustum component rotatably connected to the inner wall of the receiving frame; a circular ring block fixedly connected to the inner wall of the receiving frame; and two square plates provided on the inner wall of the receiving frame, which are elastically connected by a connecting spring. A sealing mechanism is provided on the receiving frame to seal the inner wall of the receiving frame.

[0008] Preferably, the receiving frame is a hollow cuboid structure, and the receiving frame is used to be inserted into the inner wall of the steel beam.

[0009] Preferably, the hollow frustum component is hollow, and a chamfer is provided on the side of the hollow frustum component away from the receiving frame, and the steel beam is provided with through holes for easy installation.

[0010] Preferably, the two block plates are fixedly connected to the inner wall of the receiving frame by bolts, and the connecting spring is located in the inner space of the ring block.

[0011] Preferably, the sealing mechanism includes a placement groove and a return spring. The placement groove is disposed on the inner wall of the receiving frame. A hollow cylindrical block is fixedly connected to the outer wall of the square plate. A connecting cylinder is elastically connected to the inner wall of the hollow cylindrical block through a return spring. A cover plate is rotatably connected to the side of the connecting cylinder away from the return spring.

[0012] Preferably, the connecting cylinder is slidably connected to the inner wall of the hollow cylindrical block, and the cover plate is used to insert into the placement groove to form a seal.

[0013] Preferably, a sealing ring is provided on the side of the cover plate near the placement groove to enhance the sealing of the cover plate, and a handle is provided on the side of the cover plate away from the placement groove to facilitate the removal of the cover plate.

[0014] By employing the above technical solution, this utility model provides a novel high-strength, fatigue-resistant steel beam structure. It possesses at least the following beneficial effects:

[0015] 1. This utility model incorporates a connecting mechanism where, during bolt fixing, the bolt nut contacts the outer side of the hollow frustum component, and the bolt shank contacts the inner side of the hollow frustum component. This prevents the bolt from directly contacting the steel beam, avoiding damage to the anti-rust layer of the steel beam during bolt tightening. The advantage of this design is that the anti-rust layer of the steel beam remains intact, preventing scratches or friction damage during tightening, thus effectively preventing rust on the steel beam surface, extending the service life of the structure, and ensuring the corrosion resistance and fatigue resistance of the connection points, further enhancing the strength and safety of the structure.

[0016] 2. This utility model incorporates a connecting mechanism that inserts the steel beams on both sides between two receiving frames. At this time, the connecting spring provides a restoring force to the block plate and simultaneously provides a force that brings the receiving frames, which are fixed to the block plate, closer together until the holes on the steel beams engage with the hollow frustum-shaped component, thus pre-fixing the steel beams. Because this connecting spring has an elastic design, it ensures that when the block plate is in the predetermined position, the receiving frames can stably support the initial position of the steel beams, thereby achieving rapid and accurate positioning. This avoids structural instability caused by inaccurate installation and greatly improves installation efficiency and precision.

[0017] 3. This utility model incorporates a sealing mechanism. When tightening the bolts, the cover plate is pulled open and rotated, exposing the interior of the receiving frame for easy installation and adjustment. After all installation steps are completed, the cover plate is rotated to align with the placement groove, and a return spring seals the receiving frame. The return spring design ensures that the cover plate returns to its original position after installation and interlocks with the placement groove to form a seal, preventing displacement or loosening due to external forces and ensuring long-term stability of the sealing performance. Through this elastic structural design, the inner wall of the receiving frame is effectively sealed, preventing the entry of external moisture, contaminants, and corrosive gases, thus ensuring the protective effect of the internal structure. Simultaneously, the application of the sealing structure greatly enhances the equipment's corrosion resistance, preventing corrosion of internal components caused by the external environment during long-term use, and improving the overall structural durability and fatigue resistance.

[0029] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. 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.

[0030] Please see Figure 1 - Figure 9As shown, this utility model provides a technical solution: a novel high-strength, fatigue-resistant steel beam structure, including a steel beam 1, a connecting mechanism 2 on the steel beam 1, the connecting mechanism 2 including: a receiving frame 21, a hollow frustum component 22 rotatably connected to the inner wall of the receiving frame 21, a ring block 23 fixedly connected to the inner wall of the receiving frame 21, and two square plates 24 provided on the inner wall of the receiving frame 21, the two square plates 24 being elastically connected by a connecting spring 25; a sealing mechanism 3 is provided on the receiving frame 21, the sealing mechanism 3 is used to seal the inner wall of the receiving frame 21, this sealing mechanism 3 can not only effectively prevent external moisture and pollutants from entering the receiving frame 21, but also improve the corrosion resistance of the structure and extend its service life. The receiving frame 21 is a hollow cuboid structure. The connecting frame 21 is inserted into the inner wall of the steel beam 1, serving a supporting function. The hollow cuboid structure of the connecting frame 21 has good weight bearing capacity and space utilization efficiency, effectively distributing the load of the steel beam 1 and enhancing the overall structural strength. The hollow frustum 22 is hollow and is used for fastening with bolts. The side of the hollow frustum 22 away from the connecting frame 21 is chamfered. The steel beam 1 is provided with through holes for easy installation, facilitating the insertion of the hollow frustum 22 into the through holes of the steel beam 1. The ring block 23 is also inserted into the through holes of the steel beam 1. By setting through holes and chamfers, the ease and accuracy of installation can be effectively improved, ensuring the stability of the connection and the uniformity of force distribution. The two square plates 24 are fixedly connected to the inner wall of the connecting frame 21 with bolts, and the connecting spring 25 is located in the inner space of the ring block 23.

[0031] The sealing mechanism 3 includes a placement groove 31 and a return spring 33. The placement groove 31 is located on the inner wall of the receiving frame 21. A hollow cylindrical block 32 is fixedly connected to the outer wall of the square plate 24. A connecting cylinder 34 is elastically connected to the inner wall of the hollow cylindrical block 32 via the return spring 33. A cover plate 35 is rotatably connected to the side of the connecting cylinder 34 away from the return spring 33. Through a precise elastic structure design, the sealing mechanism 3 effectively seals the inner wall of the receiving frame 21, ensuring its protective performance and preventing damage to the inner wall due to external factors during long-term use. The corrosion of the components is addressed by the sliding connection between the connecting cylinder 34 and the inner wall of the hollow cylindrical block 32. The cover plate 35 is used to insert into the placement groove 31 to form a seal. A sealing ring 36 is provided on the side of the cover plate 35 near the placement groove 31 to enhance the sealing of the cover plate 35. A handle 37 is provided on the side of the cover plate 35 away from the placement groove 31 to facilitate the removal of the cover plate 35. The design of the sealing ring 36 increases the sealing effect between the cover plate 35 and the placement groove 31. The handle 37 makes the cover plate 35 more convenient to operate when needed, reducing the difficulty of operation.

[0032] In use, the novel high-strength, fatigue-resistant steel beam structure of this invention involves inserting the steel beams 1 on both sides between two receiving frames 21. At this time, the connecting spring 25 provides a restoring force to the block plate 24 and also provides a force that brings the receiving frames 21, which are fixed to the block plate 24, closer together until the holes on the steel beams 1 engage with the hollow frustum-shaped piece 22, thus pre-fixing the steel beams 1. Because the connecting spring 25 has an elastic design, it ensures that when the block plate 24 is in the predetermined position, the receiving frames 21 can stably support the initial position of the steel beams 1, thereby achieving rapid and accurate positioning and avoiding structural instability caused by inaccurate installation, greatly improving installation efficiency and accuracy.

[0033] Then, bolts are passed through the hollow frustum 22, fixing the two sides of the hollow frustum 22 in place. Simultaneously, the two receiving frames 21 are also brought closer together and locked, thus achieving a stable fixation of the steel beam 1. During bolt fixing, the bolt nut contacts the outer side of the hollow frustum 22, and the bolt shank contacts the inner side of the hollow frustum 22, preventing direct contact between the bolt and the steel beam 1 and avoiding damage to the anti-rust layer of the steel beam 1 during bolt tightening. The advantage of this design is that the anti-rust layer of the steel beam 1 remains intact, preventing scratches or friction damage during tightening, effectively preventing rust on the surface of the steel beam 1, extending the service life of the structure, and ensuring the corrosion resistance and fatigue resistance of the connection parts, further enhancing the structural safety.

[0034] Furthermore, when tightening the bolts, the cover plate 35 is pulled open and rotated, exposing the interior of the receiving frame 21 for easy installation and adjustment. After completing all installation steps, the cover plate 35 is rotated to align with the placement groove 31, and the receiving frame 21 is sealed by the return spring 33. The design of the return spring 33 ensures that the cover plate 35 returns to its original position after installation and interlocks with the placement groove 31 to form a seal, preventing the cover plate 35 from shifting or loosening due to external forces, and ensuring the long-term stability of the sealing performance. Through this elastic structural design, the inner wall of the receiving frame 21 is effectively sealed, preventing external moisture, contaminants, and corrosive gases from entering, thereby ensuring the protective effect of the internal structure. At the same time, the application of the sealing structure greatly enhances the corrosion resistance of the equipment, avoiding corrosion problems of internal components caused by the external environment during long-term use, and improving the overall durability and fatigue resistance of the structure.
