In the figure: 1. the main beam, 11, a web plate, 12, an assembly hole, 13, a bolt, 14, a nut, 2, a secondary beam, 21, a wing plate, 3, a stiff beam, 31, a steel wire, 4 and a support beam.

Detailed Description

The technical solutions in the embodiments of the present invention will be described clearly and completely with reference to the accompanying drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without creative work belong to the protection scope of the present invention.

Referring to fig. 1, the present invention provides a technical solution: the utility model provides a high-rise building girder steel structure, including girder 1, girder 1 has a plurality of roots, and be equipped with a plurality of auxiliary beams 2 between two horizontal girders 1, weld powerful roof beam 3 between two vertical girders 1, powerful roof beam 3 cross assembly, increase the reinforcing bar in the auxiliary beam 2 structure replaces traditional structure, make the big promotion of roof beam body bearing capacity, because the floor sinks to take place the displacement between the roof beam body many and lead to the roof beam body to twist reverse, so powerful roof beam 3 adopts cross assembly's mode, improve the roof beam body and bear the torque range.

Specifically, the girder 1 is made of I-shaped steel with the waist height of 14.6mm, the web plate 11 is welded between the upper flange and the lower flange of the girder 1, the I-shaped steel can reduce the weight of the girder, and meanwhile, the web plate 11 is welded obliquely, so that the shearing force applied to the flanges is reduced, and the bearing capacity of the girder is improved.

Particularly, H-shaped steel with the waist height of 10mm is selected for use as the auxiliary beam 2, the supporting beam 4 is welded between the two vertical auxiliary beams 2, the auxiliary beam 2 can be just clamped with the web plate of the main beam 1 due to the size, the reinforcing steel channel is selected for use as the supporting beam 4, the distance between the stiffening plates is determined by the stress of the beam body, and the maximum torque of the beam body is improved by the supporting beam 4.

Particularly, perpendicular welding has pterygoid lamina 21 between the flange about the auxiliary girder 2 end, and 1 web of girder and pterygoid lamina 21 are opened has pilot hole 12, has cup jointed bolt 13 in the pilot hole, and 13 ends of bolt pass through the nut 14 fastening, change traditional welded connection mode, with auxiliary girder 2 embedding main girder 1 inside, make its structure reach unification, block the auxiliary girder through the cooperation of 1 flange of girder and web 11, the roof beam body bearing capacity after the pouring concrete is stronger and difficult the emergence is twistd reverse.

Particularly, strength roof beam 3 chooses for use diameter 10mm twisted steel, and 3 intersections of strength roof beam pass through the fastening of steel wire 31, and twisted steel can bear great torsional force, and two perpendicular girders 1 of 3 fastenings of strength roof beam prevent to twist reverse, alleviate roof beam body weight, and make roof beam body structure compacter.

The working principle is as follows: girder 1 chooses the I-steel that the size matches each other for use with auxiliary girder 2, lighten the weight of the roof beam body greatly, reduce the pressure of building to the ground, prevent that the building body from sinking, slant welding has web 11 between the girder 1 upper and lower edge of a wing, the bearing capacity of the roof beam body has been improved, embed inside girder 1 with auxiliary girder 2, make its structure reach unification, block the auxiliary girder through the cooperation of girder 1 edge of a wing and web 11, the roof beam body bearing capacity after the pouring concrete is stronger and difficult the emergence twists reverse, the shear force that the edge of a wing receives has been alleviateed, and alleviate the sunken phenomenon of floor, the torsion that the roof beam body can bear has been strengthened with stiff girder 3 to the back beam 4 simultaneously, when the floor sinks, can prevent that the roof beam.
