[0019] The technical scheme in the embodiments of the utility model will be clearly and completely described in combination with the drawings in the embodiments of the utility model, obviously, the described embodiments are only some embodiments of the utility model, not all the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by those skilled in the art without creative labor belong to the protection scope of the utility model.

[0020] As Figure 1As shown in the structural diagram of the current combination beam, it can be seen that the outer periphery of the combination beam is welded by separate flange plates (reference numeral a), web plates (reference numeral b) and bottom plates (reference numeral c), and the welds are all at the corners of the plate connections. Since full penetration welding is currently used, a large amount of welding material is consumed, and a large amount of manual support is required during the welding process. In addition, the welds (reference numerals d-1, d-2, d-3 and d-4) at the corners are prone to form gaps, burrs and other defects, which can accelerate the corrosion of the local metal and even form small holes and cracks, thereby affecting the product quality and service life.

[0021] As shown in Figure 2 and Figure 3 , a new U-shaped combination beam includes an outer surrounding plate and a cross partition plate 2. The outer surrounding plate includes two one-piece bent plates 1. The one-piece bent plate 1 includes a flange portion 11, a web portion 12 and a bottom portion 13. The bottom portions 13 of the two one-piece bent plates 1 are connected by welding. The cross partition plate 2 is welded to one one-piece bent plate 1 on each side. A first included angle is formed between the flange portion 11 and the web portion 12. A second included angle is formed between the web portion 12 and the bottom portion 13. The first included angle opens outward from the combination beam. The second included angle opens inward from the combination beam. A support 3 is arranged at the first included angle. The surface of the one-piece bent plate 1 on the side facing the inside of the combination beam is provided with a plurality of reinforcing ribs 4.

[0022] The one-piece bent plate 1 is obtained by directional bending of a whole steel plate by a numerical control plate bending machine. Compared with the conventional combination beam which is welded by separate plate pieces, one one-piece bent plate 1 in this application can replace the flange plate, web plate and bottom plate on one side, which can greatly reduce the number of welds, reduce the consumption of welding material and labor, and can also transfer the necessary welds from the corners to the middle of the plate (welds such as Figure 2 indicated by reference numeral e), which can reduce the construction difficulty and reduce the welding defects that affect the service life of the combination beam.

[0023] In practical application, the cross partition plate 2 includes a plate main body 21, a first connecting plate 22 and a second connecting plate 23, which can enhance the torsional strength of the combination beam. The plate main body 21 is provided with a through hole, which has a certain weight reduction effect and is convenient for construction and maintenance.

[0024] In practical application, the support 3 is a triangular plate which is welded to the flange portion 11 and the web portion 12, respectively, which can enhance the overall strength of the combination beam and prolong the service life.

[0025] The first included angle and the second included angle are both obtuse angles and equal, i.e. the flange portion 11 is parallel to the bottom portion 13. Since the one-piece bent plate is processed by a numerical control bending machine, the machining precision is higher and the tolerance is better controlled compared with separate plate welding, and the machining efficiency is also higher.

[0026] In practical application, the reinforcing rib 4 is arranged along the length direction of the composite beam, and the load bearing capacity and stability of the beam can be enhanced.

[0027] The embodiment of the utility model has the advantages of:

[0028] The integral bending plate is used to replace most parts needing welding, so that the number of welds can be reduced, the welding material consumption and labor cost can be reduced, the welds are transferred to the middle part of the plate, welding at the corner connection is avoided, defects such as gaps and burrs can be avoided, corrosion is not easy to occur, and the service life of the composite beam can be effectively prolonged.

[0029] The above is only a specific embodiment of the utility model, but the protection scope of the utility model is not limited to this, any skilled person in the art can easily think of changes or replacements within the technical range disclosed by the utility model, which should be covered in the protection scope of the utility model. Therefore, the protection scope of the utility model should be subject to the protection scope of the claims.
