[0026] The technical scheme of the utility model will be further specifically described below by means of specific embodiments and in combination with the drawings:

[0027] Example 1: in a steel structure building, a frame structure system does not set up vertical support, can adopt larger column spacing, and can provide larger use space. However, the rigidity of pure frame structure is poor, as a single lateral force resisting system, once the steel frame is damaged, the consequence will be very serious. The braced steel frame system is an ideal lateral force resisting system, which is evolved on the basis of the steel frame system, that is, between certain spans or several spans in the frame system, the braced truss composed of frame beams, columns and support inclined rods is arranged along the vertical direction of the frame, and the lateral load is borne by the frame and the braced truss together. Under the action of horizontal force, the support rod only bears axial tension and compression, and works together with the rigidly connected frame through the deformation coordination of the floor slab, forming a double lateral force resisting structure system. The steel frame bracing system has various types, including steel frame center bracing and steel frame eccentric bracing, which are suitable for buildings of different heights according to different types. Among them, the center bracing has the best lateral stiffness, which can be divided into cross bracing, single inclined rod bracing, herringbone bracing and V-shaped bracing. The lateral stiffness of cross bracing is twice that of single bracing. The cross bracing has intersecting nodes of inclined rods, especially when the inclined rods are made of square tubes, the node structure is complex, the rod needs to be disconnected, and a partition plate needs to be arranged inside, which has complex processing technology.

[0028] Therefore, in order to overcome the defects of complex node structure and processing technology in the prior art, the utility model provides a clamping plate type cross bracing node, as shown in Figure 1 and Figure 2As shown, including continuous support 1 and metal splint 3, and haunch 2 on both sides of continuous support 1, metal splint 3 is fixed on both sides of the connection node of haunch 2 and continuous support 1. Wherein, continuous support 1 and two sides haunch 2 cross connection, two metal splint 3 are fixed on both sides of the cross node of haunch 2 and continuous support 1 connection, the overall structure is simple, wherein continuous support 1 and haunch 2 can be directly utilized profile component, metal splint 3 can be obtained by numerical control blanking, and the processing technology is simple.

[0029] Two sides haunch 2 is mirror image about continuous support 1. The axis of two sides haunch 2 can be located on a straight line, which can improve the stability of the node, increase the lateral stiffness of the structure and improve the carrying capacity.

[0030] The cross section of continuous support 1 and haunch 2 is the same and is a symmetrical cross section. The cross section of continuous support 1 and haunch 2 is the same, which can directly utilize profile component, simplify material selection, and the symmetrical cross section can make the internal force more evenly distributed in the support node, improve the lateral stiffness of the structure, and the calculated length of continuous support 1 perpendicular to two directions of haunch 2 is consistent, which can improve the balance of the structure.

[0031] Metal splint 3 is a central symmetric polygonal plate, which can be directly obtained by numerical control blanking, and the metal splint 3 on both sides of the connection node is symmetrical about the connection node, which can facilitate the conduction of internal force in the support node, and the polygonal arrangement can increase the carrying capacity of the support node to internal force; the metal splint 3 is also symmetrical about the axis of continuous support 1, so that the center of metal splint 3 coincides with the center of the connection node, which helps the support node to bear force evenly and increases the stability of the support node.

[0032] Metal splint 3 is fixed on continuous support 1 by fillet weld 4. The fixed connection by fillet weld 4 improves the stability of the support node, and the fixed mode of fillet weld 4 can easily control the welding deformation and has low processing cost; metal splint 3 is fixedly connected with two sides haunch 2 by fillet weld 4, the internal force received by one side haunch 2 can be conducted to metal splint 3 through fillet weld 4, and then conducted to the other side haunch 2 through fillet weld 4 after passing through metal splint 3, fillet weld 4 can bear forces and moments in various directions, so that the internal force can be conducted in the support node and the internal force distribution in the support node is more uniform, reducing stress concentration phenomenon, thereby improving the overall lateral stiffness.

[0033] In addition, the overall structure of the utility model is simple, can be obtained by fixed process steps, and the overall size can be adjusted, so it is convenient to manufacture. Therefore, it can also be profiled to reduce the manufacturing cost.

[0034] Example 2: The continuous support 1 and the two side brackets 2 are both made of square steel pipe profiles, which are relatively easy to obtain. According to the needs of the processing drawings, the square steel pipes can be cut into the specified lengths using precise cutting equipment to ensure that the dimensions of each section of square steel pipe meet the design requirements.

[0035] Specifically, the square steel tube profile used in the continuous support 1 is a diagonal steel component, and the two side brackets 2 also use square steel tube profiles. The square steel tube profiles used in the brackets 2 and the diagonal steel components used in the continuous support 1 have the same cross-section and are both square. The square steel tube profiles used in the brackets 2 and the diagonal steel components used in the continuous support 1 form a cross-shaped support node. Then, at the intersection of the square steel tube profiles used in the brackets 2 and the diagonal steel components used in the continuous support 1, the square steel tube profiles used in the brackets 2 are cut using a cutting process. The steel pipe profile is cut into two independent parts according to the required length of the bracket 2, which are the brackets 2 on both sides of the continuous support member 1. After cutting, the end face of the bracket 2 is cut again according to the angle between the axis of the bracket 2 on both sides and the axis of the continuous support member 1 to ensure that the axis of the bracket 2 on both sides is on the same straight line and perpendicular to the axis of the continuous support member 1. The calculated lengths of the two ends of the inclined steel member used in the continuous support member 1 are consistent in both directions, which can reduce stress concentration and improve the stability and load-bearing capacity of the structure.

[0036] Example 3: As Figure 2 As shown, in this embodiment, the metal clamp 3 consists of two flat steel plates located on both sides of the connection node between the corbel 2 and the continuous support member 1. The flat steel plates used for the two metal clamps 3 are both centrally symmetrical octagonal plates. Two parallel long sides 32 of the octagonal flat steel plates are parallel to the axis of the corbel 2 on both sides, and two parallel short sides 31 of the metal clamps are perpendicular to the axis of the corbel 2 on both sides. The lengths of the two short sides 31 of the metal clamps are equal to the lengths of the first and second parallel hypotenuses 33 and the second parallel hypotenuses 34 of the metal clamps. The lengths of the two short sides 31 of the metal clamps are equal to the side lengths of the square cross-section of the inclined steel member used in the continuous support member 1.

[0037] Specifically, the angle formed by the hypotenuse 33 of the two parallel metal plates and the long side 32 of the adjacent metal plate is 135°, and the angle formed by the hypotenuse 33 of the two metal plates and the short side 31 of the adjacent metal plate is also 135°; the angle formed by the hypotenuse 34 of the two metal plates and the long side 32 of the adjacent metal plate is 135°, and the angle formed between the hypotenuse 34 of the two metal plates and the short side 31 of the adjacent metal plate is also 135°. Of course, the angle setting here is only applicable to this embodiment. If the shape of the flat steel plate is different, the angle needs to be changed to facilitate the cooperation with the continuous support 1 and the bracket 2 and ensure the effect of internal force transmission.

[0038] Such a setting increases the contact area with the continuous support 1 and the two side corbels 2, the angle between the metal clamp bevel one 33 and the metal clamp long edge 32 and the metal clamp short edge 31 of the adjacent metal clamp, which can better conduct internal force, so that the internal force can be evenly distributed on the support node, and the two flat steel plates are symmetrical about the cross connection node, and the flat steel plate can be cut and formed by a numerical control machining machine according to the processing diagram size, which can ensure the size accuracy and surface quality of the metal clamp 3, and provide a good foundation for subsequent connection and assembly; The two flat steel plates are symmetrical about the axis of the continuous support 1, which can make the support node bear evenly and increase the stability of the support node; The flat steel plate and the continuous support 1 are fixed by the fillet weld 4, which is fixed and connected by the fillet weld 4, which improves the stability of the support node, and the fixed mode of the fillet weld 4 can easily control the welding deformation and has low processing cost. Before connection, the relative position and angle of the two flat steel plates and the continuous support 1 need to be ensured, then the professional welding equipment is used to weld the fillet weld 4 on the contact surface of the flat steel plate and the continuous support 1. During the welding process, the welding speed and temperature should be controlled to ensure the uniformity and firmness of the weld.

[0039] The two flat steel plates are also fixed and connected with the two side corbels 2 by the fillet weld 4, the internal force on one side corbel 2 is transmitted through the fillet weld 4, and the internal force is transmitted to the other side corbel 2 through the two flat steel plates by the fillet weld 4; The two metal clamp long edges 32 in the octagonal flat steel plate are parallel to the axis of the two side corbels 2. Before fixing, the relative position and angle of the corbel 2 and the two flat steel plates need to be ensured. Then, the welding equipment is used to weld the fillet weld 4 on the contact surface of the corbel 2 and the flat steel plate. The welding speed and temperature should be controlled during welding to ensure the firmness and smoothness of the weld.

[0040] During the welding process, the quality and firmness of the weld should be ensured to avoid defects such as virtual welding and slag inclusion. After welding, the weld is checked and polished to remove burrs and uneven parts generated during welding, improving the surface quality of the part.
