Description

Technical Field

[0001] The present utility model relates to the technical field of steel components, in particular to a lateral displacement resistant transverse bracing steel component. Background Art

[0002] In steel structure engineering, especially in prefabricated frame structures, high-rise steel structure buildings, bridge steel towers, machine room frameworks, curtain wall support frameworks and other structures, it is often necessary to arrange transverse support structures between components to enhance the overall seismic capacity and lateral stability.

[0003] At present, common transverse bracing steel components have relatively simple structures, and most of them adopt single-layer cross rods or cross tie rods to be welded and fixed between frame nodes. Although such structures have a certain connecting effect, they have the following main problems: First, the lateral displacement resistance effect is limited, and it is prone to shaking or inter-node offset when subjected to lateral forces such as wall joints and earthquakes; Second, the node stiffness is insufficient, and it is difficult to replace or adjust after the connecting piece deforms, which affects the overall structural life. Most of them are welded non-detachable structures, which are difficult to install and adjust, and are not conducive to later maintenance or component replacement.

[0004] Therefore, there is an urgent need for a lateral displacement resistant transverse bracing steel component to improve the stability and safety of prefabricated steel structures in actual use. Contents of the Utility Model

[0005] The purpose of the present utility model is to provide a lateral displacement resistant transverse bracing steel component to solve the problems of poor lateral stiffness and inconvenient construction and maintenance proposed in the above background art.

[0006] To achieve the above purpose, the present utility model provides the following technical solution: a lateral displacement resistant transverse bracing steel component, comprising side wall plates and vertical beams, wherein the vertical beam is located between two groups of side wall plates, a connecting seat is welded at the upper flange of the vertical beam, sockets are respectively inserted and connected on both sides of the connecting seat, a cross beam is inserted and connected in the socket, the connecting end of the cross beam and the side wall plate is fixed by a T-shaped head, a pin plate is welded at the lower flange of the vertical beam, a diagonal brace is welded between the T-shaped head and the pin plate, and a connecting arm is fixed between the lower flange of the vertical beam and the side wall plate.

[0007] As a further technical solution of the present utility model, the vertical beam, the diagonal braces and the cross beams form a triangular transverse bracing structure, and two groups of upper and lower adjacent vertical beams are symmetrically arranged.

[0008] As a further technical solution of the present utility model, the vertical beam, four groups of diagonal braces and two groups of connecting arms together form a "meter" shaped structure.

[0009] As a further technical solution of the present utility model, the socket is inserted into the connecting seat, a cover plate is additionally installed on a side of the socket away from the connecting seat, and a cover plate bolt is fixedly connected between the socket and the cover plate.

[0010] As a further technical solution of this utility model, the crossbeam extends through the cover plate, and the crossbeam is fixedly connected to the outer wall of the socket with fixing bolts, and the crossbeam is fixedly connected to the T-heads with T-head bolts.

[0011] As a further technical solution of this utility model, the T-shaped head has a slot machined on its edge. The slot is a concave steel sheet with openings at the top and bottom. The top of the diagonal brace is welded and fixed to the slot, and the bottom of the diagonal brace is welded to the pin.

[0012] As a further technical solution of this utility model, an arm seat is fixedly connected between the connecting arm and the side wall panel, and a connecting bolt is fixedly connected between the connecting arm and the vertical beam wing.

[0013] As a further technical solution of this utility model, the inner sides of the connecting seat are provided with inner grooves for fixing the socket, and the socket is fixed to the connecting seat by bolts.

[0014] Compared with the prior art, the beneficial effects of this utility model are as follows: by setting up vertical beams, diagonal braces, horizontal beams, T-shaped heads, pins and connecting arms, a stable triangular horizontal brace unit and an overall "rice" shaped frame are formed in the structure. The top of the diagonal brace is welded to the slot at the edge of the T-shaped head, and the bottom is welded to the pin. With the rigid connection between the horizontal beam and the vertical beam, it has a geometric self-locking force effect. The upper and lower sets of vertical beams are fixed by the connecting arms, which enhances the spatial stability of the overall frame and resists the lateral shear deformation or vibration impact that may occur on the construction site, thereby improving the resistance to lateral displacement. By incorporating a connecting seat, socket, cover plate, fixing bolts, cover plate bolts, and T-head bolts, the crossbeam is designed to be detachable and installable at both ends. After the crossbeam is inserted into the socket, it is fixed by bolts in the socket and the inner groove of the connecting seat. Multiple locking mechanisms are achieved using the fixing bolts and T-head bolts. A cover plate is added at the far end, and the sealing is further reinforced by the cover plate bolts. This design not only ensures a secure installation and precise positioning but also facilitates quick replacement in case of crossbeam deformation. Attached Figure Description

[0017] The following will clearly and completely describe the technical solutions in the embodiments of the present utility model with reference to the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only part of the embodiments of the present utility model, not all of them. Based on the embodiments of the present utility model, all other embodiments obtained by a person of ordinary skill in the art without creative work shall fall within the protection scope of the present utility model.

[0018] Please refer to Figure 1-6 , the present utility model provides an embodiment: an anti-side sway cross-braced steel member, comprising side wall plates 1 and vertical beams 6, the vertical beam 6 is located between two sets of side wall plates 1, a connecting seat 5 is welded at the upper flange of the vertical beam 6, two sides of the connecting seat 5 are respectively inserted with sockets 4, a cross beam 3 is inserted into the socket 4, the connecting end of the cross beam 3 and the side wall plate 1 is fixed by a T-shaped head 2, a pin plate 8 is welded at the lower flange of the vertical beam 6, a diagonal brace 7 is welded between the T-shaped head 2 and the pin plate 8, a connecting arm 14 is fixed between the lower flange of the vertical beam 6 and the side wall plate 1, an arm seat 15 is fixedly connected between the connecting arm 14 and the connecting side of the side wall plate 1, and a connecting bolt 16 is fixedly connected between the connecting arm 14 and the flange of the vertical beam 6; Specifically, as shown in Figure 1 , Figure 2 and Figure 6 , by arranging the vertically symmetric vertical beams 6 and connecting arms 14, the force between adjacent vertical beams 6 is clearer. One end of the connecting arm 14 is fixed on the side wall plate 1, and the other end is fixed on the flange of the vertical beam 6, which improves the stiffness and stability of the overall member under transverse load, and reduces the side sway risk of the member during construction under external conditions such as earthquakes.

[0019] The vertical beam 6, the diagonal brace 7 and the cross beam 3 form a triangular cross-brace structure, two sets of upper and lower adjacent vertical beams 6 are symmetrically arranged, and the vertical beam 6, four sets of diagonal braces 7 and two sets of connecting arms 14 together form a "rice" shaped structure; Specifically, as shown in Figure 1 , Figure 2 and Figure 3As shown, by setting diagonal braces 7, with their tops welded to T-heads 2 and their bottoms welded to pins 8, a stable triangular structure is formed between the diagonal braces 7, the vertical beams 6, and the horizontal beams 3. This structure has good geometric self-locking characteristics and can be converted into axial force transmission when the component is under stress, thereby improving shear and lateral stiffness and enhancing the stability and durability of the joint.

[0020] The edge of the T-head 2 is machined with a slot 10. The slot 10 is a concave steel sheet with openings at the top and bottom. The top of the diagonal brace 7 is welded to the slot 10 and the bottom of the diagonal brace 7 is welded to the pin 8. Specifically, such as Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 and Figure 6 As shown, the crossbeam 3 can be double-fixed to the side wall panel 1 through the T-head 2 and the connecting seat 5. While ensuring installation accuracy, it is convenient for later maintenance or replacement, and prevents the crossbeam 3 from loosening or shifting after long-term use. This ensures that the whole component still has reliable lateral stability support when subjected to lateral force.

[0021] The socket 4 is inserted into the connector 5. A cover plate 12 is installed on the side of the socket 4 away from the connector 5. A cover plate bolt 13 is fixedly connected between the socket 4 and the cover plate 12. A crossbeam 3 extends out from the cover plate 12. A fixing bolt 11 is fixedly connected between the crossbeam 3 and the outer wall of the socket 4. A T-head bolt 9 is fixedly connected between the crossbeam 3 and the T-head 2. The connector 5 has inner grooves on both sides for fixing the socket 4. The socket 4 and the connector 5 are fixed by bolts. Specifically, such as Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 5 As shown, the T-head bolts 9, fixing bolts 11, and cover plates 12, etc., connect and fasten the socket 4 so that the socket 4 can be disassembled while ensuring the assembly firmness between the crossbeam 3 and the socket 4, avoiding structural loosening due to vibration or displacement. The cover plate bolts 13 reinforce the crossbeam 3, control the slippage of the crossbeam 3 in the socket 4, and improve the overall structure's resistance to lateral displacement.

[0022] Working principle: The vertical beam 6 is set between the two sets of side wall panels 1, and the connecting seat 5 and pin 8 are welded to the upper and lower flanges respectively. The two ends of the horizontal beam 3 are inserted into the socket 4 in sequence, and the socket 4 is then inserted and fixed in the connecting seat 5. The connection and positioning between the horizontal beam 3 and the side wall panel 1 is achieved by fixing bolts 11 and T-head bolts 9. The middle part of the horizontal beam 3 is connected to the T-head 2. The edge of the T-head 2 is provided with a slot 10 for welding the upper end of the diagonal brace 7. The lower end of the diagonal brace 7 is welded to the pin 8. The two adjacent sets of vertical beams 6 are connected by a connecting arm. 14 is connected, with one end of the connecting arm 14 fixed to the flange of the vertical beam 6, and the other end fixed to the side wall plate 1 via the connecting bolt 16 and the arm seat 15. When the structure is subjected to lateral load or vibration, the crossbeam 3 bears the horizontal force transmission, and the force is transmitted to the diagonal brace 7 through the T-head 2. The diagonal brace 7 then distributes the force to the pin plate 8 and the vertical beam 6. The vertical beam 6 and the connecting arm 14 form an upper and lower tie rod structure, which rebounds the force back to the side wall plate 1, forming a stable triangular and "rice" shaped rigid frame, thereby controlling lateral displacement and improving node stability.
