[0029] EMBODIMENT

[0030] As Figs. 1-3 The steel structure rear-mounted auxiliary beam fixing device comprises a roof steel beam 1, a pair of auxiliary steel beams 2 and a pair of fixing plates 3.

[0031] The roof steel beam 1 is in the shape of an I-beam, and a pair of auxiliary steel beams 2 are detachably and spacedly abutted on both sides of the web of the roof steel beam 1. The roof steel beam 1 uses the auxiliary steel beams 2 on both sides of the web to enhance the stability and safety of the whole structure, including enhancing the bearing capacity, adapting to different stress conditions and avoiding the position of bolts. This design makes the connection of the roof and the indoor frame more stable, especially at the node, which is achieved by setting the web and the corresponding connecting piece.

[0032] Each auxiliary steel beam 2 is provided with a gasket 7 for reducing the local stress concentration at the connection between the roof steel beam 1 and the fixing plate 3, and the gasket 7 abuts on the lower flange of the roof steel beam 1. If the local bearing stress on site is too large and needs to be connected by pasting, the gasket 7 is fixed between the gasket 7 and the auxiliary steel beam 2 to prevent the gasket 7 from moving under pressure or vibration. If the local bearing stress on site is relatively small and needs to be connected by embedding, the gasket 7 is installed between the gasket 7 and the auxiliary steel beam 2, and the gasket 7 is easier to replace.

[0033] Each auxiliary steel beam 2 is vertically abutted with a reinforcing rib 4 for reducing the local stress at the connection between the roof steel beam 1 and the fixing plate 3 on the side of the upper flange of the roof steel beam 1, and the reinforcing rib 4 is also vertically welded on the web of the roof steel beam 1, which has the effect of connecting the auxiliary steel beam 2 with the roof steel beam 1 and limiting the position of the auxiliary steel beam 2.

[0034] A pair of fixing plates 3 are detachably arranged on the upper flange and the lower flange of the roof steel beam 1, and the fixing plates 3 abut on the roof steel beam 1. Four adjusting studs 5 for reinforcing the connection between the roof steel beam 1 and the fixing plates 3 are arranged on each fixing plate 3 arranged on the upper flange of the roof steel beam 1, and one end of each adjusting stud 5 towards the lower flange of the roof steel beam 1 completely penetrates the upper flange and the lower flange of the roof steel beam 1 and the two fixing plates 3. The adjusting studs 5 improve the overall disassembly without reducing the installation precision and the bearing capacity.

[0035] Two fastening bolts 6 are arranged at both ends of each adjusting stud 5 and abut against each other, the outer edges of both ends of each adjusting stud 5 are respectively provided with outer threads in opposite directions, the inner threads of the two fastening bolts 6 arranged at both ends of each adjusting stud 5 are in opposite directions, and the inner threads of the two fastening bolts 6 arranged at both ends of each adjusting stud 5 are in opposite directions and match the outer threads of the corresponding adjusting stud 5, the two fastening bolts 6 arranged at both ends of each adjusting stud 5 can provide more stable fixing effect, and ensure that the adjusting stud 5 will not be easily loosened or displaced when bearing external force, thereby ensuring the stability and safety of the whole structure.

[0036] The four adjusting studs 5 are arranged in a linear array on the fixed plate 3, and the four adjusting studs 5 are located at the four corners of the fixed plate 3, the pair of auxiliary steel beams 2, the pair of fixed plates 3 and the pair of reinforcing ribs 4 are located on the same plane and between two adjacent adjusting studs 5.

[0037] The above only describes the preferred embodiments of the present application and is not intended to limit the present application, and various modifications and changes can be made by those skilled in the art. Any modification, equivalent replacement, improvement, etc. made within the spirit and principles of the present application shall be included in the protection scope of the present application.
