[0019] The present invention will be described in detail below with reference to the accompanying drawings and embodiments.

[0020] Example: Ancient building roof support beams, such as Figure 1-Figure 5As shown, it includes a rafter column 2 and a crossbeam 1 fixedly connected to both ends of the rafter column 2, the crossbeam 1 includes a plurality of metal load-bearing beams 4 fixedly connected to each other and a wooden connecting shell 3 fixed to the outside of the connected metal load-bearing beams 4 by glue, the metal load-bearing beam 4 includes a connecting pipe 41 and a connecting piece 42 located on both sides of the connecting pipe 41, a plurality of bolt holes are opened on the connecting piece 42, the metal load-bearing beam 4 is fixedly connected to the bolt holes by a plurality of connecting bolts, and the metal load-bearing beam 4 is made of carbon structural steel. The metal load-bearing beam 4 made of this material has extremely high strength and light weight. The crossbeam 1 composed of a plurality of metal load-bearing beams 4 fixedly connected to each other increases the strength of the crossbeam 1, and the wooden connecting shell 3 is used to make the crossbeam 1 have the decoration of ancient buildings. The decorative style adopts a high-strength steel metal load-bearing beam 4 as the main body to bear the overall weight of the roof, with a stronger load-bearing capacity. At the same time, a whole beam 1 is composed of multiple metal load-bearing beams 4 and a connecting shell 3 that can be completely fixed on the outer end surface of the connected metal load-bearing beams 4. This design eliminates the need to find long-growing, long and complete trees as raw materials during manufacturing, reduces the difficulty of production and reduces the felling of old trees, and maintains the green environment to a certain extent. At the same time, there is no need to find larger transportation tools to equip and transport the longer beam 1 during transportation. It only needs to be split into several smaller individual metal load-bearing beams 4 and transported to the construction site, reducing the difficulty of transportation.

[0021] like Figure 1-Figure 5 As shown, the middle section of the metal load-bearing beam 4 is provided with connecting grooves 43 on both sides for connecting the rafters 2. The rafters 2 include connecting columns 21 and connecting heads 22 located at both ends of the connecting columns 21 and capable of being placed in the connecting grooves 43. The connecting heads 22 fixedly connected to both sides of the same rafter 2 are arranged perpendicular to each other to form a relatively stable roof support structure. By using connecting bolts 2, the connecting heads 22 can be fixed in the connecting grooves 43 to realize the connection between the rafters 2 and the beams 1, thereby ensuring the stability of the structure.

[0022] like Figure 1-Figure 5As shown, the connecting shell 3 is composed of two wooden shells 31 connected by a mortise and tenon structure set on the connecting surface. The mortise and tenon structure is set to a serrated shape, thereby increasing the contact area of the two connected wooden shells 31 to increase the friction between the two and improve the stability of the connection. The wooden shell 31 is further bonded to the outer end face of the metal load-bearing beam 4 with glue to improve the connection stability between the connecting shell 3 and the metal load-bearing beam 4. A receiving groove for placing a connecting bolt 1 is provided on the wooden shell 31 near the metal load-bearing beam 4 to accommodate the connecting bolt protruding from the connecting piece 42, thereby increasing the rationality of the structural connection. The outer end face of the connecting shell 3 is coated with KNM22 fluorosilicone concentrated acid anti-corrosion coating to improve the corrosion resistance of the connecting shell 3 and the service life of the connecting shell 3. The connecting shell 3 does not directly bear the gravity of the roof as a decoration, so that even if the connecting shell 3 is corroded and damaged, it will not affect the safety performance of the building, which greatly guarantees the safety and service life of the ancient building.

[0023] Working principle: align the connecting pieces 42 on multiple metal load-bearing beams 4 with each other, use connecting bolts 1 to pass through the corresponding bolt holes to connect and fix them to ensure the connection stability of the two metal load-bearing beams 4, and then fix the rafters 2 in the connecting grooves 43 opened on the metal load-bearing beams 4 through connecting bolts 2. Then, use glue to fix the two corresponding wooden shells 31 on the outside of the connected metal load-bearing beams 4 to obtain a complete beam 1, which not only has the architectural style of ancient buildings, but also has the load-bearing strength of modern buildings. At the same time, when using the utility model as a roof support beam, the wooden connecting shell 3 does not directly bear the gravity of the roof, but uses a metal load-bearing beam 4 made of carbon structural steel to support the weight. Even if the wooden connecting shell 3 is corroded and damaged, the safety of the ancient building can be guaranteed.
