Description

Technical Field

[0001] This utility model belongs to the field of steel structure technology, and in particular relates to a prefabricated H-shaped steel structure beam flange plate reinforcement component. Background Technology

[0002] H-shaped steel structures have advantages such as lightweight, high strength, fast construction, good seismic resistance, energy saving and environmental protection in prefabricated buildings. They are prefabricated in factories with high precision, convenient on-site installation, high space utilization, low overall cost, and recyclability, making them a commonly used structural component in prefabricated buildings.

[0003] H-beams consist of two relatively parallel flanges and a web connecting the two flanges. The flanges are located at the upper and lower ends of the H-beam and are perpendicularly connected to the web. They mainly play the role of resisting bending and compression, bearing most of the load-bearing capacity of the H-beam structure and maintaining the strength stability of the beam during the stress process.

[0004] Wedge-shaped cover plates are typically installed at specific locations on the flange plates of H-shaped steel beams. They increase the local thickness of the flange plates, effectively improving the bending and shear resistance in that area. This prevents the flange plates from locally yielding or failing when the beam is under load. Therefore, we need to design a prefabricated flange plate reinforcement component for H-shaped steel beams, using a structure that reinforces the connection between the flange plate and the wedge-shaped cover plate. After being connected to the flange plate, this increases the overall stiffness of the H-shaped steel beam, constrains the beam's deformation under load, reduces the beam's deflection under vertical loads and lateral displacement under horizontal loads, maintains structural stability, enhances resistance to overturning and instability, and strengthens the rigidity and integrity of the flange plate joint. Utility Model Content

[0005] The purpose of this utility model is to provide a prefabricated H-shaped steel structure beam flange plate reinforcement component, which has the advantages of improving the overall stiffness of the H-shaped steel structure beam, restraining the deformation of the beam under load, reducing the deflection of the beam under vertical load and the lateral displacement under horizontal load, maintaining structural stability, and enhancing the rigidity and integrity of the flange plate node, so as to solve the above-mentioned technical problems.

[0007] Preferably, square U-shaped plates are fixedly connected to both sides of the web plate by bolts, and the side of the square U-shaped plate away from the web plate is fixedly connected to the stiffening plate by bolts.

[0008] Preferably, four lower connecting plates are fixedly connected to one side of the lower flange plate, and the upper connecting plate and the lower connecting plate are fixedly connected to the opposite side by bolts with reinforcement members.

[0009] Preferably, the tops of the four lower connecting plates are fixedly connected to lower horizontal corner braces by bolts, and a reinforcing plate is fixedly connected between the lower horizontal corner braces and the upper horizontal corner braces.

[0010] Preferably, the surface of the fixing sleeve is fixedly connected with a plurality of stiffening ribs by bolts, and the plurality of stiffening ribs are fixedly connected to the wedge-shaped cover plate by bolts.

[0011] The beneficial effects of this utility model are:

[0012] 1. This utility model uses the combination of L-shaped vertical plates, square U-shaped plates and stiffening plates to alleviate stress concentration at the connection point when the square steel and flange plates are connected and reinforced, so that the stress is transmitted and distributed more evenly, preventing fatigue failure caused by stress concentration. After the flange plates are reinforced and connected with the wedge-shaped cover plates, the overall stiffness of the H-shaped steel structure beam is improved, which can achieve the purpose of improving the overall stiffness of the H-shaped steel structure beam, restraining the deformation of the beam under load, reducing the deflection of the beam under vertical load and the lateral displacement under horizontal load, maintaining structural stability, and enhancing the rigidity and integrity of the flange plate node.

[0013] 2. By setting up a square U-shaped plate, this utility model can increase the connection area between the web plate and the stiffening plate, making the connection between the web plate and the stiffening plate tighter, effectively transmitting tensile and compressive loads, reducing relative displacement and loosening at the connection between the web plate and the stiffening plate, and limiting the deformation of the web plate and the stiffening plate under load.

[0014] 3. By setting up the lower horizontal corner brace, this utility model effectively prevents the square steel from buckling out of plane under the influence of the flange plate, increases the lateral stiffness of the connection structure between the square steel and the web and flange plate, improves the overall stability, and reduces the risk of deformation and instability of the connection structure between the square steel and the web and flange plate under load.

Detailed Implementation

[0022] In the following description, embodiments of the prefabricated H-shaped steel structure beam flange plate reinforcement component of this utility model will be described with reference to the accompanying drawings.

[0023] Figure 1-4This invention illustrates an embodiment of a prefabricated H-shaped steel beam flange reinforcement component, comprising a square steel 1, a fixing sleeve 2 fixedly connected to the surface of the square steel 1, web plates 3 fixedly connected to both sides and the front side of the fixing sleeve 2, multiple flange plates 4 fixedly connected to the top and bottom of the three web plates 3, an L-shaped vertical plate 5 fixedly connected to the fixing sleeve 2 and the web plates 3 by bolts, both sides of the web plates 3 fixedly connected to the L-shaped vertical plate 5 by bolts, and the side of the L-shaped vertical plate 5 away from the web plates 3 fixedly connected to the square steel 1 and the fixing sleeve 2 by bolts. The connection is achieved by a stiffening plate 7 between the two flange plates 4, and square U-shaped plates 6 are bolted to both sides of the web plate 3. The side of the square U-shaped plate 6 away from the web plate 3 is bolted to the stiffening plate 7. The square U-shaped plates 6 increase the connection area between the web plate 3 and the stiffening plate 7, making the connection tighter, effectively transmitting tensile and compressive loads, reducing relative displacement and loosening at the connection point, and limiting the deformation of the web plate 3 and the stiffening plate 7 under load. Four upper connecting plates 8 are fixedly connected to one side of the upper flange plate 4, and four lower connecting plates 9 are fixedly connected to one side of the lower flange plate 4. Reinforcing members 10 are bolted to the facing sides of the upper and lower connecting plates 8 and 9. Upper horizontal corner braces 12 are bolted to the bottom of the four upper connecting plates 8, and lower horizontal corner braces 11 are bolted to the top of the four lower connecting plates 9. A reinforcing plate 13 is fixedly connected between the lower horizontal corner braces 11 and the upper horizontal corner braces 12. The design effectively prevents the square steel 1 from buckling out of plane under the influence of the flange plate 4, increases the lateral stiffness of the connection structure between the square steel 1 and the web plate 3 and the flange plate 4, improves the overall stability, and reduces the risk of deformation and instability of the connection structure between the square steel 1 and the web plate 3 and the flange plate 4 under load. The top and bottom of multiple flange plates 4 are fixedly connected with wedge-shaped cover plates 15, and the surface of the fixing sleeve 2 is fixedly connected with multiple stiffening ribs 14 by bolts. The multiple stiffening ribs 14 are fixedly connected to the wedge-shaped cover plates 15 by bolts.

[0024] Working Principle: In use, the L-shaped vertical plate 5 is bolted to the front and rear sides of the web plate 3, thereby stabilizing the connection between the web plate 3, the fixing sleeve 2, and the square steel 1. Then, the wedge-shaped cover plate 15 is welded to the top and bottom of the flange plate 4. In steel structures, this helps the flange plate better withstand bending moments and shear forces, making the force transmission smoother under load. The stiffening plate 7 then supports the upper and lower wedge-shaped cover plates 15, ensuring a stable connection between them. Since the square U-shaped plate 6 is bolted to the stiffening plate 7 and the web plate 3, the square U-shaped plate 6 increases the connection between the web plate 3 and the stiffening plate. The connection area of ​​7 makes the connection between the web plate 3 and the stiffening plate 7 tighter, effectively transmitting tensile and compressive loads, reducing relative displacement and loosening at the connection between the web plate 3 and the stiffening plate 7, and limiting the deformation of the web plate 3 and the stiffening plate 7 under load. Multiple stiffening ribs 14 are connected to the wedge-shaped cover plate 15 by bolts, making the connection node between the wedge-shaped cover plate 15 and the flange plate 4 more secure. Subsequently, the reinforcement member 10 plays a fixing role between the upper connecting plate 8 and the lower connecting plate 9, making the connection node between the upper connecting plate 8 and the lower connecting plate 9 and the lower horizontal corner brace 11 and the upper horizontal corner brace 12 more stable. Finally, the flange plate 4 and the wedge-shaped cover plate 15 are more stably reinforced on the surface of the square steel 1.

[0025] In summary, this prefabricated H-shaped steel beam flange reinforcement component, through the combined use of L-shaped vertical plate 5, square U-shaped plate 6, and stiffening plate 7, alleviates stress concentration at the connection point when the square steel 1 and flange plate 4 are connected and reinforced, allowing for more uniform stress transmission and distribution, preventing fatigue failure caused by stress concentration. After the flange plate 4 is reinforced and connected with the wedge-shaped cover plate 15, the overall stiffness of the H-shaped steel beam is improved. This achieves the goal of increasing the overall stiffness of the H-shaped steel beam, constraining the beam's deformation under load, reducing the beam's deflection under vertical loads and lateral displacement under horizontal loads, maintaining structural stability, and enhancing the rigidity and integrity of the flange plate joint.
