Description

Technical Field

[0001] The utility model relates to the technical field of building frame structures, in particular to a plate-reinforced cross-bracing node. Background Art

[0002] In steel-structured buildings, the frame structure system does not have vertical supports, allowing for larger column spacing and providing a larger usable space. However, pure frame structures have poor rigidity. As a single lateral force-resisting system, the consequences of a steel frame failure will be severe. The braced steel frame system is an ideal lateral force-resisting system, evolving from the steel frame system. Specifically, within one or several spans of the frame system, a supporting truss consisting of frame beams, columns, and diagonal bracing rods is installed vertically along the frame to share lateral loads with the steel frame. Under the action of horizontal forces, the supporting rods only bear tensile and compressive axial forces, and through the deformation coordination of the floor slab, they work together with the rigid frame to form a dual lateral force-resisting structural system. There are many different types of steel frame support systems, including centrally supported and eccentrically supported steel frames. Depending on the type, they are suitable for buildings of different heights. Among them, the central support has the best lateral stiffness and can be divided into cross support, single diagonal support, herringbone support and V-shaped support; the lateral stiffness of the cross support is twice that of the single support, but the cross support has an intersection node of the diagonal support, especially when the diagonal support uses a square tube section, the node structure is complex, and the rod needs to be disconnected and partitions need to be set inside, and the processing technology is complicated. The Chinese patent document CN111395537A, published on July 10, 2020, discloses a prefabricated building oblique support node steel structure, comprising a column, one side of which is fixedly mounted with two mounting and positioning blocks, a vertically symmetrical oblique support clamped between the two mounting and positioning blocks, the side of the oblique support passing through a fixed sleeve with a fixed shaft, both ends of the fixed shaft passing through the mounting and positioning blocks, a mounting node fixedly clamped between the two oblique supports, screw holes provided on both sides of the mounting node, a fastening swivel movably mounted at the bottom of the mounting node, a rotating shaft movably mounted in the middle of the fastening swivel, a fixed column fixedly connected to the bottom of the fastening swivel, the mounting node is fixed to the column by the fixing column and the fixing hook sleeved at its end, and the side of the mounting node is mounted on the mounting and positioning blocks by fixing bolts to increase the overall strength. However, the above-mentioned oblique support node steel structure is complex in structure, requires the rods to be disconnected, and has a complex manufacturing process and high processing costs. Utility Model Content

[0003] The purpose of the utility model is to solve the problem that when the cross support in the prior art adopts a square tube cross-section, the node structure is complex, the rods need to be disconnected, partitions need to be set inside, and the processing technology is complicated. The utility model provides a cross support node with plate reinforcement, which has the characteristics of simple node structure, no need to interrupt the continuous steel support, no need to set internal partitions, simple manufacturing process and low manufacturing cost.

[0004] The technical solution adopted by the present invention to solve the above-mentioned technical problems is a plate-reinforced cross-support node, comprising a continuous support and corbels arranged on both sides of the continuous support, wherein the continuous support is a rectangular steel tube arranged obliquely, and the corbels are symmetrically located on the left and right sides of the continuous support and on the same straight line, and end plates are provided at the connection between the corbels and the continuous support, and side plates are connected between the side edges of the end plates on both sides of the continuous support, and the continuous support is welded and fixed to the end plates and the side plates. The continuous support of the present invention is an oblique steel member; the corbels are steel members arranged in a mirror image with the continuous support, which are disconnected at the connection position of the continuous support to become two independent parts; the end plates are located on the outer surface of the continuous support and are fitted with the end faces of the corbels, and are distributed with the continuous support as the center of symmetry; the side plates are located on the outer surface of the continuous support, parallel to the corbels, and are fixed to the end plates on both sides. In this way, the utility model provides a cross-bracing node reinforced with a plate, which has the advantages of easy component processing, no need to interrupt the continuous steel support, no need to set up internal partitions, simple manufacturing process and low manufacturing cost; it solves the problem that the cross-bracing in the existing technology has a complex node structure when the diagonal brace adopts a square tube cross-section, the rod needs to be disconnected, partitions need to be set up inside, the processing process is complex and the cost is high.

[0005] Preferably, the width of the end plate is greater than the same-side length of the continuous support, and the width of the side plate is adapted to the same-side length of the continuous support. The side plate and the end plate are secured together by a groove weld. This structure minimizes welding deformation, and the groove is located at the edge of the side plate, resulting in a small and symmetrical weld, which contributes to structural stability.

[0006] Preferably, the thickness of the end plates is no less than that of the side plates, which in turn is no less than the wall thickness of the continuous brace. A thicker end plate can compensate for the higher stresses experienced at the connection. Because the end plates connect the continuous brace and the corbel, they must withstand significant shear forces and bending moments. Therefore, increasing the thickness of the end plates can improve their load-bearing capacity and resistance to deformation. A side plate thickness no less than the wall thickness of the continuous brace ensures that the side plates have at least the same strength and rigidity as the continuous brace, thus reinforcing the continuous brace at the connection.

[0007] Preferably, the corbel is a rectangular steel tube with the same cross-section as the continuous support, the length of the end plate is greater than the length of the same side of the corbel, the length of the side plate is adapted to the length of the side of the end plate, and the corbel is fixed to the end plate by welding. The corbel and the continuous support have the same cross-sectional dimensions to ensure that both have similar mechanical properties and load-bearing capacity. The length of the end plate is greater than the length of the same side of the corbel to provide a larger contact area, thereby improving the load-bearing capacity and stability of the node. The length of the side plate matches the side dimensions of the end plate to ensure that the side plate can completely cover the junction of the end plate and the corbel, providing sufficient reinforcement and support; the fixing of the corbel to the end plate by welding can ensure that the connection between the corbel and the end plate is sufficiently strong; an integral structure can be formed by welding to improve the strength and rigidity of the node.

[0008] Preferably, triangular extensions are provided at both ends of the end plate. The extensions extend in the same direction as the length of the continuous support, and the edges of the extensions are welded to the continuous support. This design prevents the weld lines between the end plate and the continuous support from converging on the same cross-section of the continuous support, dispersing stress and reducing stress concentration, thereby improving the fatigue life of the joint.

[0009] Preferably, reinforcing ribs are provided between the corbel and the end plates, with 4-6 ribs on each end plate. This arrangement effectively increases the local stiffness and overall stability of the joint, improving structural rigidity and preventing excessive deformation under load. Adding ribs between the corbel and end plates significantly improves the joint's resistance to bending and shearing.

[0010] Preferably, the cross-section of the continuous support and the corbel is square, the length of the end plate is not less than 1.5 times the side length of the corbel cross-section, the width of the end plate is the sum of the side length of the cross-section of the continuous support and 2 times the thickness of the side plate, and the thickness of the end plate is not less than 1.5 times the thickness of the side plate.

[0011] As another optional option, the cross-section of the continuous support and the corbel is rectangular, the long side of the corbel cross-section is parallel to the length direction of the continuous support, the length of the end plate is not less than 1.5 times the length of the corbel cross-section, the width of the end plate is the sum of the cross-sectional width of the continuous support and 2 times the thickness of the side plate, and the thickness of the end plate is not less than 1.5 times the thickness of the side plate.

[0012] Preferably, the angle between the continuous support and the corbel is 45-90 degrees. A larger angle can provide better stability because it can more effectively resist lateral loads; a smaller angle can provide higher load-bearing capacity.

[0013] The beneficial effect of the present invention is that it effectively solves the problem that when the cross support of the prior art adopts a square tube cross-section, the node structure is complex, the rods need to be disconnected, partitions need to be set inside, and the processing technology is complicated. The plate-reinforced cross support node of the present invention has the characteristics of simple node structure, no need to interrupt the continuous steel support, no need to set internal partitions, simple manufacturing process and low manufacturing cost.

[0020] The specific implementation of the technical solution of the utility model will be further described below through examples and in conjunction with the accompanying drawings.

[0021] exist Figure 1 Figure 2In one embodiment shown, a plate-reinforced cross-bracing node comprises a continuous support 1 and corbels 2 disposed on either side of the continuous support 1. The continuous support 1 is a rectangular steel tube disposed obliquely. The corbels 2 are symmetrically located on the left and right sides of the continuous support 1 and are in the same straight line. End plates 3 are provided at the connection between the corbels 2 and the continuous support 1. The end plates 3 and the corbels 2 are fixed by welds, and the internal forces of the corbels 2 are transmitted to the end plates 3. Side plates 4 are connected between the side edges of the end plates 3 on either side of the continuous support 1. The internal forces of the end plates 3 are transmitted to the side plates 4. The continuous support 1 is welded to the end plates 3 and the side plates 4. The continuous support 1 of the present utility model is an oblique steel member. The corbels 2 are steel members disposed in a mirror image of the continuous support 1, and are disconnected at the connection position of the continuous support 1 to form two independent parts. The end plates 3 are located on the outer surface of the continuous support 1 and are in contact with the end faces of the corbels 2. The end plates 3 are located on the outer surface of the continuous support 1 and are parallel to the corbels 2. The side plates 4 are located on the outer surface of the continuous support 1 and are fixed to the end plates 3 on both sides. The plate-reinforced cross-bracing node is a specific type of diagonal bracing node for building frames, designed to enhance structural stability and lateral resistance. The continuous brace 1, a single-piece rectangular steel tube arranged diagonally, provides the primary support. This structure effectively transfers and distributes loads, enhancing the overall stability of the structure. The corbels 2 are segmented components located on either side of the continuous brace 1, symmetrically positioned on the center and aligned in a straight line. This layout evenly distributes loads, enhancing the structure's symmetry and stability.

[0022] The end plate 3 is a flat plate located at the connection between the corbel 2 and the continuous support 1. It transmits torque and enhances the connection strength, thereby strengthening the stability of the connection point. The end plate 3 is fixed to the continuous support 1 and the corbel 2 by welding, ensuring effective force transmission. The side plates 4 are flat plates connecting the side edges of the end plates 3 on either side of the continuous support 1, providing reinforcement and stability. In this embodiment, the width of the end plate 3 is greater than the same-side length of the continuous support 1. The portion that extends beyond the sides of the continuous support 1 is used for welding to the side plates 4. The thickness of the end plate 3 is no less than the thickness of the side plates 4. The width of the end plate 3 is greater than the same-side length of the continuous support 1, which means that the end plate 3 not only covers the entire side of the continuous support 1 but also extends beyond its boundaries. This provides a larger contact area, thereby improving the load-bearing capacity and stability of the node. The thickness of the end plate 3 is greater than that of the side plates 4 to compensate for the concentrated stress on the end plate 3 at the connection. Because the end plate 3 connects the continuous support 1 and the corbel 2, it needs to withstand large shear forces and bending moments. Therefore, increasing the thickness of the end plate 3 can improve its load-bearing capacity and resistance to deformation.

[0023] The side panels can increase the rigidity of the node and prevent the continuous support 1 from deforming excessively under load. In this embodiment, the width of the side panels 4 matches the length of the same side of the continuous support 1, and the thickness of the side panels 4 is no less than the wall thickness of the continuous support 1. The side panels 4 are fixed to the end panels 3 by groove welds 5. The width of the side panels 4 matches the side dimensions of the continuous support 1, ensuring that the side panels 4 can completely cover the side of the continuous support 1 and provide support between the two end panels 3. The thickness of the side panels 4 is no less than the wall thickness of the continuous support 1, ensuring that the side panels 4 have at least the same strength and rigidity as the continuous support 1. This prevents the side panels 4 from becoming a weak link in the structure and ensures the overall performance of the node. This thickness requirement ensures that the side panels 4 will not easily yield or break when subjected to load. By properly selecting the thickness of the end panels 3 and 4, the node can maintain good performance under various load conditions. The side panels 4 are fixed to the end panels 3 by groove welds 5. By creating a groove at the junction of the two welded parts, the fusion area is increased and the weld strength is improved. This structure can ensure that the connection between the side plate 4 and the end plate 3 is more secure, avoiding cracks or breakages in a high-stress environment, and ensuring that the supporting node can operate stably for a long time.

[0024] The entire support node (continuous support, end plates, and side plates) of this embodiment is fixed by welding. This connection method has high strength and rigidity, can effectively transmit forces and moments, and ensure the stability of the structure under various load conditions. This structure of cross-bracing nodes reinforced with panels can effectively improve the structure's ability to resist lateral displacement and is suitable for a variety of complex building environments and load conditions. The combination of cross bracing and corbels can effectively resist lateral loads and bending deformation. The addition of side plates and end plates enhances the rigidity of the support node area and improves the overall performance of the structure.

[0025] The angle between the continuous support 1 and the corbel 2 is usually between 45 and 90 degrees. Within the angle range of 45-90 degrees, the support node can provide better mechanical performance. A larger angle can provide better stability because it can more effectively resist lateral loads; a smaller angle can provide higher load-bearing capacity. Figure 1 Figure 2 The angle between the continuous support 1 and the corbel 2 shown is 80 degrees.

[0026] exist Figure 3In a preferred embodiment shown, the corbel 2 is a rectangular steel tube with the same cross-section as the continuous support 1. The length of the end plate 3 is greater than the length of the same side of the corbel 2, and the length of the side plate 4 matches the length of the side of the end plate 3. The corbel 2 and the end plate 3 are fixed together by welding. Although the cross-sectional structure of the corbel 2 in the present invention does not necessarily have to be the same as that of the continuous support 1, the use of a rectangular steel tube with the same cross-section as the continuous support 1 ensures that the two have the same mechanical properties and load-bearing capacity. The length of the end plate 3 is greater than the length of the same side of the corbel 2, indicating that the end plate 3 has a larger contact area with the continuous support 1, thereby improving the load-bearing capacity and stability of the support node. The length of the side plate 4 matches the side dimensions of the end plate 3, ensuring that the side plate 4 can completely cover the intersection of the end plate 3 and the corbel 2, providing sufficient reinforcement and support. The corbel 2 and the end plate 3 are fixed together by welding: Welding is a common connection method that ensures a sufficiently strong connection between the corbel 2 and the end plate 3. Through welding, a single structure can be formed, improving the strength and rigidity of the node. These characteristics demonstrate that the design prioritizes the strength and stability of the joint, particularly under high and dynamic loads. By optimizing the design of the corbel 2, end plate 3, and side plate 4, and employing high-quality welding techniques, the joint's performance can be significantly improved, ensuring the safety and reliability of the entire structure. In practical applications, engineers also need to consider factors such as material selection, welding process control, and anti-corrosion treatment of the joint to ensure long-term stable operation under various environmental conditions.

[0027] In such Figure 4 In another embodiment shown, triangular extensions 6 are provided at both ends of the end plate 3. The extension direction of the extension 6 is consistent with the length direction of the continuous support, and the edge of the extension 6 is welded and fixed to the continuous support 1. Triangular extensions 6 are provided at both ends of the end plate 3. This structure avoids the welding lines of the end plate 3 and the continuous support 1 from being concentrated on the same cross-section of the continuous support 1, which can disperse stress and reduce stress concentration, thereby improving the fatigue life of the node. At the same time, this structure also increases the contact area between the end plate 3 and the continuous support 1, thereby improving the bearing capacity and stability of the connection. The design of the extension 6 can enhance the stability of the node and reduce structural deformation caused by load changes or vibrations; by reducing stress concentration, the fatigue performance of the node can be improved, its service life can be extended, and the performance of the plate-reinforced cross-support node can be significantly improved, such as Figure 3 The triangular extension 6 of the illustrated embodiment has a vertex angle of 90 degrees.

[0028] In another embodiment, reinforcing ribs 7 are provided between the ends of the corbel 2 and the end plate 3, and there are 4-6 reinforcing ribs 7 on each end plate 3. The reinforcing ribs 7 provided between the corbel 2 and the end plate 3 are located between the ends of the corbel 2 and the end plate 3. This structure can further increase the local stiffness and overall stability of the support node. By adding reinforcing ribs 7 between the corbel 2 and the end plate 3, the bending and shearing resistance of the node can be significantly improved. At the same time, the reinforcing ribs 7 can also help disperse stress, reduce stress concentration, and contribute to improving the fatigue resistance and durability of the support node. There are 4-6 reinforcing ribs 7 on each end plate 3, that is, 2-3 reinforcing ribs are provided at each end of the end plate 3. This number range provides sufficient strength and stiffness, while also taking into account the economy of the material and the feasibility of processing, such as Figure 4 In the illustrated embodiment, reinforcing ribs 7 are provided between the ends of the corbel 2 and the end plates 3 . There are six reinforcing ribs on each end plate 3 , that is, three reinforcing ribs are provided on each end of the end plate 3 .

[0029] In another embodiment, the cross-sections of the continuous support 1 and corbel 2 are square. The length of the end plate 3 is no less than 1.5 times the side length of the corbel 2 cross section. The width of the end plate 3 is the sum of the side length of the continuous support 1 cross section plus twice the thickness of the side plate 4. The thickness of the end plate 3 is no less than 1.5 times the thickness of the side plate 4. The square cross-sections of the continuous support 1 and corbel 2 provide a relatively uniform and stable load-bearing structure. The length of the end plate 3 is no less than 1.5 times the side length of the corbel 2 cross section. This ensures that the end plate 3 covers the entire cross-section of the corbel 2, providing sufficient connection area and enhancing the strength and rigidity of the joint. The width of the end plate 3 is the sum of the side length of the continuous support 1 cross section plus twice the thickness of the side plate 4. This width takes into account the dimensions of the continuous support 1 and the thickness of the side plate 4, ensuring that both sides of the end plate 3 are welded to the side plate 4. The thickness of the end plate 3 is no less than 1.5 times the thickness of the side plate 4. This ensures that the end plate 3 has sufficient load-bearing capacity in the thickness direction and prevents excessive deformation under load. These specific dimensional requirements ensure that the end plate 3 has sufficient strength and rigidity in all directions, thereby improving the stability and bearing capacity of the entire node. Figure 3 In the illustrated embodiment, the steel tubes of the continuous support 1 and corbel 2 have a square cross-section, with a side length of 200 mm and a wall thickness of 12 mm. The rectangular end plates 3 are 400 mm long, twice the side length of the corbel 2 cross-section. Their width is the sum of the cross-sectional length of the continuous support 1 and twice the thickness of the side plates 4. The thickness of the side plates 4 is the same as the wall thickness of the continuous support 1, 12 mm. The width of the end plates 3 is 224 mm, and their thickness is 30 mm, 2.5 times the thickness of the side plates 4.

[0030] In another embodiment, the cross-sections of the continuous support 1 and the corbel 2 are rectangular, the long side of the cross-section of the corbel 2 is parallel to the length of the continuous support 1, the length of the end plate 3 is not less than 1.5 times the length of the cross-section of the corbel 2, the width of the end plate 3 is the sum of the cross-sectional width of the continuous support 1 and twice the thickness of the side plate 4, and the thickness of the end plate 3 is not less than 1.5 times the thickness of the side plate 4. In the plate-reinforced cross-bracing node of this embodiment, the cross-sections of the continuous support 1 and the corbel 2 are rectangular, and the long side of the cross-sectional width of the corbel 2 is parallel to the length of the continuous support 1. The length of the end plate 3 is not less than 1.5 times the length of the cross-sectional length of the corbel 2. This ensures that the end plate 3 covers the entire cross-sectional area of the corbel 2, thereby providing sufficient connection area and enhancing the strength and rigidity of the node. The width of the end plate 3 is the sum of the side length of the cross-sectional area of the continuous support 1 and twice the thickness of the side plate 4. This width takes into account the size of the continuous support 1 and the thickness of the side plate 4, ensuring that both sides of the end plate 3 are welded to the side plate 4. The thickness of the end plate 3 is not less than 1.5 times the thickness of the side plate 4. This ensures that the end plate 3 has sufficient bearing capacity in the thickness direction and prevents excessive deformation under load. These specific dimensional requirements ensure that the end plate 3 has sufficient strength and rigidity in all directions, thereby improving the stability and bearing capacity of the entire node. Figure 5 In the illustrated embodiment, the steel tubes of the continuous support 1 and corbel 2 have rectangular cross-sections, with a length of 300 mm, a width of 200 mm, and a wall thickness of 12 mm. The rectangular end plates 3 are 600 mm long, twice the length of the corbel 2 cross-section, and have a width equal to the sum of the cross-sectional length of the continuous support 1 and twice the thickness of the side plates 4. The thickness of the side plates 4 is the same as the wall thickness of the continuous support 1, 12 mm. The width of the end plates 3 is 224 mm, and the thickness is 30 mm, 2.5 times the thickness of the side plates 4. Figure 5 In the illustrated embodiment, reinforcing ribs 7 are provided between the ends of the corbel 2 and the end plate 3 . There are four reinforcing ribs 7 on each end plate 3 , that is, two reinforcing ribs 7 are provided at each end of the end plate 3 .

[0031] When processing the plate-reinforced cross-support node of the present invention, the continuous support 1 adopts a rectangular tube profile component, which is cut into a specified length according to the requirements of the processing drawing. The end plate 3 is formed by a CNC machining machine according to the dimensions of the processing drawing. The upper and lower edges of the end plate 3 and the continuous support 1 are fixed by fillet welds. The side plate 4 is formed by CNC machining according to the dimensions of the processing drawing, and a groove is opened on the two edges. It is fixed to the end plate 3 through the groove weld 5, and the upper and lower edges of the side plate 4 are fixed to the continuous support 1 through fillet welds; the corbel 2 adopts a rectangular tube cross-section, and the cross-section is the same as that of the continuous support 1. The component is cut according to the length of the corbel 2 through a cutting process, and the end face of the corbel is cut twice according to the angle between the corbel axis and the axis of the continuous support 1. The corbel 2 and the end plate 3 are fixed by welds to achieve equal strength connection.

[0032] The continuous support of the present invention is an oblique steel member; the corbel is a steel member mirrored to the continuous support, disconnected at the continuous support connection point to form two independent parts; the end plate is located on the outer surface of the continuous support and is in contact with the end surface of the corbel, and is distributed symmetrically with the continuous support as the center; the side plate is located on the outer surface of the continuous support, parallel to the corbel, and fixed to the end plate on both sides. Thus, the present invention provides a plate-reinforced cross-support node, which is easy to process, does not require interrupting the continuous support, does not require the installation of internal partitions, has a simple manufacturing process, and is low in cost. This solves the problem of the existing cross support technology in which the diagonal brace adopts a square tube cross-section, resulting in a complex node structure, the need to disconnect the rods, and install internal partitions, resulting in a complex manufacturing process and high cost. The present invention is easy to process. For profile members, only lofting, cutting, and beveling operations are required, without interrupting the continuous support or installing internal partitions. The manufacturing process is simple and the manufacturing cost is low. At the same time, welding deformation is small, the side plate thickness is smaller than the end plate, the bevel is opened at the edge of the side plate, and the weld size is small and symmetrical.

These can be achieved by those skilled in the art without creative work. Therefore, these embodiments that are not described in detail in the present utility model should also be regarded as specific embodiments of the present utility model and within the scope of protection of the present utility model.
