The beam supports the entire weight of the components and roof in the upper structure of the building, and is the most important part of the upper structure of the building. The beam has different names according to its specific location, detailed shape, specific function, etc. The direction of most beams is consistent with the cross section of the building. However, due to material, production and installation reasons, the span of a single beam is limited. Therefore, multiple beams need to be combined to achieve the required span. However, the connection structure of the combined beam in the prior art is inconvenient to process, and the connection strength at the processed node is low, which restricts the performance of the beam. Summary of the invention

[0003] One of the purposes of the present invention is to overcome the deficiencies in the prior art and provide a composite beam that is easy to assemble.

[0004] To achieve the above objectives, the present invention is implemented through the following technical solutions:

[0006] a first support beam, the first support beam being provided with a first lumen;

[0007] a second support beam, wherein the second support beam is provided with a second lumen; and

[0008] An inner sleeve, one end of which is located in the first tube cavity, and the other end of which is located in the second tube cavity; the inner sleeve is connected to the first support beam and the second support beam.

[0009] According to one embodiment of the present invention, a notch is provided at the end of the first support beam, and the notch is communicated with the first tube cavity; the inner sleeve can be placed at the end of the first tube cavity through the notch.

[0010] According to an embodiment of the present invention, the notch is provided at one end or both ends of the first support beam.

[0011] According to one embodiment of the present invention, the first support beam includes a first side wall, a second side wall, a first bottom plate and a first cover plate; the first side wall, the second side wall, the first bottom plate and the first cover plate form the first tube cavity; the first cover plate is shorter than the first bottom plate to form the gap.

[0012] According to one embodiment of the present invention, the first cover plate is provided with an opening; the opening is communicated with the first tube cavity; and the opening extends along the length direction of the first support beam.

[0013] According to one embodiment of the present invention, before the inner sleeve is fixedly connected to the first support beam and the second support beam, the inner sleeve can be slidably disposed in the second tube cavity along the second support beam and can slide from the second tube cavity into the first tube cavity; the two ends of the inner sleeve are respectively connected to the first support beam and the second support beam.

[0014] According to one embodiment of the present invention, the inner sleeve is C-shaped, tubular, I-shaped, or has the same shape as the first support beam and the second support beam.

[0015] According to an embodiment of the present invention, the inner sleeve includes a first flat plate, a first vertical plate, and a second flat plate; the first flat plate and the second flat plate are arranged in parallel at two ends of the first vertical plate.

[0020] In the combined beam of the present invention, the first support beam, the second support beam and the inner sleeve are processed and formed in the factory respectively. During the assembly at the use site, a part of the inner sleeve is first inserted into the second tube cavity, and the other part is exposed from the second tube cavity. During the alignment of the ends of the first support beam and the second support beam, the inner sleeve falls from the notch onto the first bottom plate of the first support beam. At this time, the inner sleeve can be slidably inserted into the second tube cavity until one end of the inner sleeve is located in the first tube cavity and the other end is located in the second tube cavity. Then, the inner sleeve and the first support beam and the second support beam are fixedly connected by welding or connecting parts. At this point, the inner sleeve connects the first support beam and the second support beam.

[0028] The present invention is described in detail below in conjunction with the accompanying drawings:

[0029] like Figure 1 , Figure 2 , Figure 3 and Figure 4 As shown, a composite beam comprises a first support beam 10, a second support beam 20 and an inner sleeve 30. The first support beam 10 is provided with a first tube cavity 17. The first support beam 10 comprises a first side wall 12, a second side wall 13, a first bottom plate 11 and a first cover plate 14; the first side wall 12, the second side wall 13, the first bottom plate 11 and the first cover plate 14 enclose the first tube cavity 17. The first cover plate 14 is provided with an opening 15. The opening 15 is connected to the first tube cavity 17. The opening 15 extends along the length direction of the first support beam 10. The length of the first cover plate 14 is shorter than the length of the first bottom plate 11, so as to form a notch 16 at each end of the first support beam 10. The notch 16 is connected to the first tube cavity 17.

[0030] The second support beam 20 is provided with a second lumen 21. The second support beam 20 has the same structure as the first support beam 10, or may be different. In this embodiment, the second support beam 20 has the same structure as the first support beam 10 except that the notch 16 is not provided, that is, the cover plate length of the second support beam 20 is the same as the bottom plate length.

[0031] The inner sleeve 30 includes a first flat plate 31 , a first vertical plate 33 and a second flat plate 32 ; the first flat plate 31 and the second flat plate 32 are arranged in parallel at two ends of the first vertical plate 33 .

[0032] The ends of the first support beam 10 and the second support beam 20 are opposite, and one end of the inner sleeve 30 is located in the first tube cavity 17, and the other end is located in the second tube cavity 21. The inner sleeve 30 is connected to the first support beam 10 and the second support beam 20. As shown in the figure, the first flat plate 31 is connected to the first cover plate 14 and the cover plate of the second support beam 20 at the same time; the second flat plate 32 is connected to the first bottom plate 11 and the bottom plate of the second support beam 20 at the same time. The first vertical plate 33 can also be connected to the first side wall plate 12 or the second side wall plate 13 to further enhance the connection strength. The first support beam 10 and the second support beam 20 are connected by the inner sleeve 30. The connection method of the inner sleeve 30 with the first support beam 10 and the second support beam 20 can be either welding or a fixed connection method connected by fasteners.

[0033] In the composite beam of the present invention, the first support beam 10, the second support beam 20 and the inner sleeve 30 can be pre-fabricated in the factory and installed at the site of use. The inner sleeve 30 is partially inserted into the second tube cavity 21 in advance, and partially protrudes from the second support beam 20, and the first support beam 10 and the second support beam 20 are aligned. The inner sleeve 30 protruding from the second support beam 20 falls on the first bottom plate 11 from the notch 16, and is partially located in the first tube cavity 17. Then the inner sleeve 30 is partially pushed into the first tube cavity 17. Finally, the inner sleeve 30 is welded to the first support beam 10 and the second support beam 20.

[0034] Before the inner sleeve is fixedly connected to the first support beam 10 and the second support beam 20 , the inner sleeve 30 can be slidably disposed in the second tubular cavity 21 along the second support beam 20 and can slide from the second tubular cavity 21 into the first tubular cavity 17 .
