Description

Technical Field

[0001] This utility model relates to the field of building steel components technology, and in particular to a reinforced building steel component. Background Technology

[0002] In steel structure engineering, T-shaped or L-shaped joints composed of vertical and horizontal steel bars are critical load-bearing parts. Under static loads and dynamic loads such as wind and earthquakes, there is a serious stress concentration phenomenon in the angle area of ​​the joint, which can easily lead to local buckling of the steel plate in the joint area, cracking of the connection weld, and other damage, thereby endangering the safety of the overall structure.

[0003] In the existing technology, the most common reinforcement method is to weld triangular stiffening plates (commonly known as stiffening ribs) at the joint angle. Although this method can improve the local stiffness of the joint area to a certain extent, it has obvious shortcomings. First, its reinforcement effect is limited to the vicinity of the joint and cannot effectively disperse and transfer concentrated stress to other parts of the component, resulting in poor stress redistribution. Second, for the overall or local bending instability that may occur when the vertical steel is used as a compression member, the traditional triangular stiffening plate provides almost no restraint, resulting in the failure to fully utilize the stable bearing capacity of the vertical steel. Utility Model Content

[0004] The purpose of this utility model is to provide a reinforced building steel component in order to solve the above-mentioned problems.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: a reinforced building steel component, comprising a vertical steel and a horizontal steel disposed at one end of the vertical steel, a triangular reinforcing plate disposed at the angle between the horizontal steel and the vertical steel, a side plate disposed at the other end of the vertical steel, a sling connecting the side plate and the reinforcing plate, an N-shaped support plate disposed on the inner side of the vertical steel, and the support plate and the side plate being flush with the horizontal steel.

[0006] Preferably, the reinforcing plate and the horizontal steel are fixed together by fastener one, the reinforcing plate and the vertical steel are fixed together by fastener two, the support plate and the vertical steel are fixed together by fastener three, and the support plate, the vertical steel and the side plate are fixed together by fastener four.

[0007] Preferably, a rod is inserted through the upper end of the reinforcing plate and the middle of the side plate, and a fixing cylinder is installed on both sides of the rod.

[0008] Preferably, the sling includes a wire rope, a swivel, and a sleeve. The two ends of the wire rope pass through the swivel and are bent into a hook shape. The sleeve is installed on the outside of the hook shape. A screw is installed on the outside of the swivel and threaded to the inside of the fixed sleeve. A nut is threaded to the outside of the fixed sleeve.

[0009] Preferably, an ear plate is installed at the middle of the outer side of the support plate, and a hook that fits against the outer side of the wire rope is installed on the outer side of the ear plate.

[0010] In summary, due to the adoption of the above technical solution, the beneficial effects of this utility model are:

[0011] 1. In this application, by setting a triangular reinforcing plate at the node and a side plate at the other end of the vertical steel, and connecting the two with slings, an internal force transmission path is constructed from the node to the far end of the vertical steel. When the node is under stress, part of the stress can be transmitted and distributed to the side plate and the vertical steel body in the form of tension through the tensioned slings, which improves the stress concentration in the node area, transforms the local high stress into the overall internal force of the component, and realizes the efficient redistribution of force.

[0012] 2. In this application, an N-shaped support plate is set up, which together with the side plate and the horizontal steel forms a stable support frame. This frame not only provides reliable intermediate support for the vertical steel, effectively constrains the bending deformation of the vertical steel, and improves its stable bearing capacity, but also serves as the end point of the force transmission path of the sling. Working together with the sling, it reliably anchors the tension transmitted by the sling, thus jointly enhancing the component's ability to resist lateral loads. Furthermore, the hooks set on the support plate play an effective intermediate support and positioning role for the sling, avoiding wear or fatigue caused by swaying and vibration during long-term use of the sling, ensuring the long-term effectiveness of the prestressed tie system, and optimizing the stress form of the sling.

[0019] 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 skilled in the art without creative effort are within the protection scope of the present utility model.

[0020] Please see Figure 1 and Figure 2 This utility model provides a technical solution: a reinforced building steel component, including a vertical steel 1 and a horizontal steel 2 set at one end of the vertical steel 1, which form a T-shaped or L-shaped node. A triangular reinforcing plate 3 is set at the angle between the horizontal steel 2 and the vertical steel 1 to enhance the rigidity of the node area and resist the initial deformation of the node. A side plate 4 is set at the other end of the vertical steel 1, and a sling 5 is connected between the side plate 4 and the reinforcing plate 3. When the reinforcing plate 3 (node) is subjected to a downward force or bending moment, the tensioned sling 5 will be stretched, thereby transferring this force to the side plate 4 at the other end of the vertical steel 1 in the form of tension. In this way, the huge stress originally concentrated in the triangular area of ​​the node is effectively diverted and redistributed to a larger area of ​​the vertical steel 1, significantly reducing the stress peak in the node area and avoiding local damage.

[0021] An N-shaped support plate 6 is provided on the inner side of the vertical steel 1. The support plate 6 and the side plate 4 are flush with the horizontal steel 2. The N-shaped support plate 6, the side plate 4, and the horizontal steel 2 together form a sturdy support frame, providing strong intermediate support for the vertical steel 1, restraining the lateral bending deformation of the vertical steel 1, thereby improving its overall stability and compressive bearing capacity.

[0022] The reinforcing plate 3 and the horizontal steel 2 are fixed together by fastener 7, the reinforcing plate 3 and the vertical steel 1 are fixed together by fastener 8, the support plate 6 and the vertical steel 1 are fixed together by fastener 9, and the support plate 6, the vertical steel 1 and the side plate 4 are fixed together by fastener 10. Fasteners 7, 8, 9 and 10 are all high-strength bolts, which ensures the reliability of the connection and facilitates later maintenance, inspection or replacement.

[0023] Specifically, such as Figure 3 As shown, a rod 11 is inserted through the upper end of the reinforcing plate 3 and the middle of the side plate 4. A fixing cylinder 12 is installed on both sides of the rod 11. The rod 11 and the fixing cylinder 12 form a double-sided anchor point, providing a reliable connection foundation for the sling 5.

[0024] The sling 5 includes a wire rope 13, a hanging ring 15, and a sleeve 14. The two ends of the wire rope 13 pass through the hanging ring 15 and are bent into a hook shape. The sleeve 14 is installed on the outside of the hook shape. In specific implementation, the sleeve 14 is fixed to both ends of the wire rope 13 by high pressure, so that the two ends of the wire rope 13 form loops and connect with the hanging ring 15. A screw 16 is installed on the outside of the hanging ring 15 and is threaded to the inside of the fixed cylinder 12. A nut 17 is threaded to the outside of the fixed cylinder 12. By rotating the nut 17, the position of the screw 16 in the fixed cylinder 12 can be adjusted, which can adjust the preload of the wire rope 13.

[0025] Specifically, such as Figure 4 As shown, an ear plate 18 is installed at the middle of the outer side of the support plate 6. A hook 19 that fits against the outer side of the wire rope 13 is installed on the outer side of the ear plate 18. The middle part of the wire rope 13 of the sling 5 rests naturally or is slightly inserted into the hook 19, thereby providing intermediate support and positioning for the sling 5, preventing it from swaying during long-term use, and optimizing the stress pattern of the sling 5.
