[0022] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts shall fall within the protection scope of the present invention.

[0023] Please refer to Figures 1-4 , an extended chord member type assembled main beam, including a base 1, a support assembly and a chord assembly. A plurality of groups of support assemblies are arranged on the base 1. The support assembly includes a longitudinal beam 2, a reinforcing rib 3 and an upper pin 4. A plurality of groups of longitudinal beams 2 are arranged on the base 1. Right-angled triangle-shaped reinforcing ribs 3 are arranged on the left and right sides of the longitudinal beam 2. An inverted T-shaped upper pin 4 is arranged above the longitudinal beam 2. The chord assembly includes a top beam 5, a positioning assembly and a locking member. A bearing groove is arranged above the upper pin 4. A positioning assembly inserted into the bearing groove is arranged below the top beam 5. The positioning assembly includes an insertion block 6, an elastic member and a clamping block 7. The insertion block 6 is inserted into the bearing groove. Moving grooves are symmetrically arranged on the left and right sides of the insertion block 6. An elastic member and a clamping block 7 are arranged in the moving groove. Two ends of the elastic member are respectively connected to the moving groove and the clamping block 7. Positioning holes adapted to the clamping block 7 are arranged on the left and right sides of the bearing groove. The insertion block 6 is connected to the upper pin 4 through a locking member.

[0024] The base 1 serves as the foundation for the entire prefabricated main beam, providing a stable support platform for the upper support components. It evenly distributes the loads from the main beam to the ground or other support structures, ensuring that the main beam does not tilt or sink during use. The several groups of longitudinal beams 2 provided on the base 1 are the main load-bearing structures of the support components. The longitudinal beams 2 are made of high-strength materials and can withstand the pressure and tension from the upper chord components and external loads. During the use of the main beam, the longitudinal beams 2 transfer the loads to the reinforcing ribs 3 and the upper pins 4, and further disperse them to the entire support structure through them. The reinforcing ribs 3 in the shape of right-angled triangles provided on both sides of the longitudinal beams 2 can effectively enhance the strength and stability of the longitudinal beams 2. The reinforcing ribs 3 and the longitudinal beams 2 form a stable triangular structure, improving the bending and torsional resistance of the longitudinal beams 2. When the main beam bears external loads, the reinforcing ribs 3 can disperse the loads over a larger area, reduce the local stress of the longitudinal beams 2, and prevent the longitudinal beams 2 from deforming or being damaged. The upper pins 4 in the shape of an inverted T provided above the longitudinal beams 2 provide connection points for the upper chord components. The bearing grooves of the upper pins 4 cooperate with the positioning components of the upper chord components to achieve the preliminary connection between the upper chord components and the support components. At the same time, the upper pins 4 also provide installation positions for the locking parts to ensure the stability of the fixed top beam 5.

[0025] In this embodiment, the elastic member includes a spring 8 and a telescopic rod 9. The spring 8 is sleeved on the telescopic rod 9. Both ends of the spring 8 and the telescopic rod 9 are respectively connected to the inner wall of the movable groove and the clamping block 7. A slope 10 is provided on the lower part of the clamping block 7. The positioning components provided below the top beam 5 include an insertion block 6, an elastic member, and a clamping block 7. When installing the upper chord components, the insertion block 6 is inserted into the bearing groove of the upper pin 4 to achieve the preliminary positioning of the upper chord components and the support components. The elastic member (spring 8 and telescopic rod 9) and the clamping block 7 in the movable grooves symmetrically provided on both sides of the insertion block 6 cooperate with the positioning holes on both sides of the bearing groove. When the insertion block 6 is inserted into the bearing groove, the clamping block 7 is snapped into the positioning hole under the action of the elastic member, ensuring the firm connection between the upper chord components and the support components. The slope 10 provided on the lower part of the clamping block 7 facilitates the insertion of the insertion block 6 into the upper pin 4. During the insertion process, the slope 10 can guide the clamping block 7 to retract into the movable groove. When the insertion block 6 is completely inserted into the bearing groove, the clamping block 7 pops out under the action of the elastic member and is snapped into the positioning hole

[0026] During actual use, the locking member includes a top plate 11, a bolt 12 and a nut 13. The insertion block 6 penetrates through the top plate 11. A bolt 12 is provided on the top plate 11. The upper pin 4 is provided with a threaded hole adapted to the bolt 12. The bolt 12 penetrates through the bolt 12 and is connected to the nut 13. Four groups of bolts 12 are provided on the top plate 11. The upper chord assembly is further strengthened in connection stability with the support assembly through the locking member. A gasket 15 is also provided between the nut 13 and the upper pin 4. The locking member includes a top plate 11, a bolt 12 and a nut 13. The insertion block 6 penetrates through the top plate 11. The bolt 12 provided on the top plate 11 passes through the threaded hole of the upper pin 4 and is connected to the nut 13. Four groups of bolts 12 are provided on the top plate 11, increasing the number of fixing points, improving the strength and stability of the connection. The gasket 15 provided between the nut 13 and the upper pin 4 increases the contact area between the nut 13 and the upper pin 4, disperses the pressure, and prevents the nut 13 from loosening. During the use of the main beam, the locking member can effectively prevent relative displacement between the upper chord assembly and the support assembly, ensuring the overall stability of the main beam.

[0027] A reinforcing block 14 is also provided between the top plate 11 and the top beam 5. The reinforcing block 14 provided between the top plate 11 and the top beam 5 can enhance the strength of the top plate 11. When the main beam bears external loads, the top plate 11 needs to bear greater pressure and tension. The reinforcing block 14 can effectively disperse the stress, prevent the top plate 11 from deforming or being damaged, and improve the overall stability and load-bearing capacity of the main beam.
