Description

Technical Field

[0001] This utility model belongs to the field of herringbone beam technology, specifically relating to a high-strength steel structure beam. Background Technology

[0002] As a highly efficient structural form, the A-frame beam has been widely used in large-span structures such as industrial plants, large stadiums, bridges, and warehouses due to its excellent load-bearing performance.

[0003] Existing A-beams, traditional reinforcement methods such as adding haunches and attaching steel plates generally have the following common defects: a large amount of on-site welding, drilling and other operations will damage the integrity of the original component and create new weak points. Once the reinforcement is completed, its stiffness and load-bearing capacity are fixed and cannot be adjusted according to future load changes. Moreover, it is difficult to remove and belongs to irreversible permanent reinforcement. Utility Model Content

[0004] The purpose of this invention is to provide a high-strength steel structure beam, which aims to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: A high-strength steel structure beam, including a chevron beam. The two ends of the A-frame beam are bolted with support frames, the middle of the A-frame beam is equipped with a central reinforcement mechanism, and the two ends of the A-frame beam are equipped with side reinforcement mechanisms. The side reinforcement mechanism includes two first reinforcement frames, which are respectively sleeved on both sides of the end face of the herringbone beam. A connecting component is provided at the bottom of the two first reinforcement frames, and the connecting component is connected to the support frame. The central reinforcement mechanism includes two second reinforcement frames, which are respectively fitted on both sides of the middle part of the herringbone beam. A frame-type bracket is installed at the bottom of each of the two second reinforcement frames, and a support component is provided at the bottom of the frame-type bracket. The support component cooperates with the bottom surface of the herringbone beam.

[0006] As a preferred embodiment of this utility model, both the upper and lower ends of the two first reinforcing frames are provided with first protrusions, and adjacent two first protrusions are connected by bolts.

[0007] In a preferred embodiment of this utility model, the connecting assembly includes a vertical plate, the surface of which is close to the surface of the support frame. A plug-in plate is provided at the bottom end of the vertical plate, and a fixing frame is fixedly provided on the side of the support frame. The surface of the plug-in plate is snapped into the fixing frame, and the plug-in plate and the fixing frame are connected by bolts.

[0008] As a preferred embodiment of this utility model, the bottom of both frame-shaped supports is provided with a flat plate, and the top of the second reinforcing frame and the bottom of the flat plate are both provided with a second protrusion, and two adjacent second protrusions are connected by bolts.

[0009] As a preferred embodiment of this utility model, a semi-circular groove is provided at the connection point of the two flat plates, and the two semi-circular grooves are combined to form a complete mounting hole. A threaded groove is provided on the inner wall of the mounting hole.

[0015] To make the above-mentioned objectives, features and advantages of this utility model more apparent and understandable, the specific embodiments of this utility model will be described in detail below with reference to the accompanying drawings.

[0016] Many specific details are set forth in the following description in order to provide a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Those skilled in the art can make similar extensions without departing from the spirit of the present invention. Therefore, the present invention is not limited to the specific embodiments disclosed below.

[0017] Secondly, the term "an embodiment" or "embodiment" as used herein refers to a specific feature, structure, or characteristic that may be included in at least one implementation of the present invention. The phrase "in one embodiment" appearing in different places in this specification does not necessarily refer to the same embodiment, nor is it a single or selective embodiment that excludes other embodiments.

[0018] Example Reference Figure 1-4 This is an embodiment of the present invention, which provides a high-strength steel structure beam, including a herringbone beam 1. Support frames 2 are bolted to both ends of the A-beam 1, a central reinforcement mechanism 4 is installed in the middle of the A-beam 1, and side reinforcement mechanisms 3 are installed at both ends of the A-beam 1. The side reinforcement mechanism 3 includes two first reinforcement frames 5, which are respectively fitted on both sides of the end face of the herringbone beam 1. The bottom of the two first reinforcement frames 5 is provided with a connecting component, which is connected to the support frame 2. The central reinforcement mechanism 4 includes two second reinforcement frames 10, which are respectively fitted on both sides of the middle part of the herringbone beam 1. The bottom of each of the two second reinforcement frames 10 is equipped with a frame-type bracket 11, and the bottom of the frame-type bracket 11 is provided with a support component, which cooperates with the bottom surface of the herringbone beam 1.

[0019] In use, the two first reinforcing frames 5 clamp the beam from both sides of the end of the A-beam 1, which is equivalent to adding strong lateral restraint to the end of the beam, effectively preventing the A-beam 1 from lateral buckling or torsional deformation when subjected to vertical loads. Through the bottom connecting components, the first reinforcing frames 5 are firmly connected to the support frame 2. Part of the force acting on the end of the A-beam 1 can be directly transmitted to the support structure through the first reinforcing frames 5, and then transmitted from the support structure to the support frame 2, forming an additional and more direct force transmission path, reducing the burden on the bolt connections of the A-beam 1 itself. The two second reinforcing frames 10 also clamp the middle of the A-beam 1 from both sides, providing strong lateral restraint to prevent problems in the area of ​​the A-beam 1 most prone to bending and instability in the span. The frame-type bracket 11 connected to the bottom of the second reinforcing frame 10, together with the support components, forms a stable frame. When the middle of the A-beam 1 bends downward due to load, the support components will provide an upward reaction force, effectively resisting the downward deflection deformation of the beam.

[0020] In summary, the support of the side reinforcement mechanism 3 and the central reinforcement mechanism 4 forms a comprehensive constraint, which significantly enhances the A-beam 1's ability to resist lateral buckling, torsion, and overall instability. This allows the beam to maintain its original shape under heavy loads. The support components of the central reinforcement mechanism 4 directly provide upward support force, offsetting part of the downward load. This enables the A-beam 1 to withstand much larger vertical loads than ordinary beams without damage or excessive deformation. This design transforms the load from the traditional single beam bearing to a system jointly bearing the load of the beam, the side reinforcement mechanism 3, and the central reinforcement mechanism 4.

[0021] Furthermore, both ends of the two first reinforcing frames 5 are provided with first protruding strips 6, and adjacent first protruding strips 6 are connected by bolts.

[0022] In use, the two first reinforcing frames 5 are respectively fitted onto the two sides of the end of the herringbone beam 1. By setting the first protrusions 6 at the upper and lower ends and fastening them together with bolts, the two originally independent first reinforcing frames 5 are connected into a complete, closed rigid frame.

[0023] Furthermore, the connecting assembly includes a vertical plate 7, the surface of which is close to the surface of the support frame 2. A plug-in plate 8 is provided at the bottom of the vertical plate 7. A fixing frame 9 is fixedly provided on the side of the support frame 2. The surface of the plug-in plate 8 is snapped into the fixing frame 9, and the plug-in plate 8 and the fixing frame 9 are connected by bolts.

[0024] In use, the plug plate 8 is inserted and placed on the fixed frame 9. The fixed frame 9 acts as a support. After being connected by bolts, it can effectively bear and transmit vertical shear force. When the A-beam 1 is subjected to a downward load, part of the load will be transmitted to the vertical plate 7 through the first reinforcing frame 5, and then directly transmitted to the fixed frame 9 and the support frame 2 through the plug plate 8. The surface of the vertical plate 7 is in close contact with the surface of the support frame 2. This large-area surface contact can effectively transmit horizontal force parallel to the plate surface.

[0025] Furthermore, both frame brackets 11 have a flat plate at their bottom, and the top of the second reinforcing frame 10 and the bottom of the flat plate are both provided with a second protrusion 12, and two adjacent second protrusions 12 are connected by bolts.

[0026] In use, the upper and lower second protrusions 12 connected by bolts form a rigid connection node with a large height. The two second protrusions 12 and the plate between them are in close contact to form a whole. This makes the force transmission from the second reinforcing frame 10 to the frame bracket 11 continuous and direct, avoiding deformation and energy loss caused by loose connection.

[0027] Furthermore, a semi-circular groove 13 is provided at the connection of the two flat plates. The two semi-circular grooves 13 are combined to form a complete mounting hole. A threaded groove is provided on the inner wall of the mounting hole. The support component includes a reinforcing rod 14. The surface of the reinforcing rod 14 is provided with a threaded surface that meshes with the threaded groove. The mounting hole is set in an inclined shape. The reinforcing rod 14 is installed at an incline into the threaded groove. A connecting plate 15 is provided at the top of the reinforcing rod 14. The top of the connecting plate 15 is close to the bottom surface of the herringbone beam 1.

[0028] When in use, when the installer rotates the reinforcing rod 14, due to the self-locking and pushing action of the thread, the reinforcing rod 14 will be screwed upward and inward along the inclined threaded hole. The upward movement of the reinforcing rod 14 will force the top connecting plate 15 to press tightly against the bottom surface of the A-beam 1. As rotation continues, a huge pre-tension force will be generated inside the reinforcing rod 14, which is equivalent to giving the A-beam 1 a continuous upward and active pushing force.
