Detailed Description
The embodiment of the utility model provides a thin-walled cold-formed steel truss roof beam and H shaped steel coupling mechanism, as shown in fig. 1-3, including transversely a plurality of H type steelframes 1 and the steel truss roof beam of arranging in proper order, the steel truss roof beam designs into variable cross section, and the steel truss roof beam sets up between two adjacent H type steel framves 1.
The end part of the steel truss girder is designed into a variable cross section to extend into the space between the upper flange 11 and the lower flange 12 of the H-shaped steel frame 1, so that the H-shaped steel frame 1 and the cold-formed thin-wall steel truss girder are designed at the same elevation.
The H-shaped steel frame 1 includes an upper flange 11 and a lower flange 12.
The steel truss girder comprises a lower chord 2, an upper chord 3, a reinforcing chord 5 and a straight web member 6.
The two ends of the lower chord 2 are arranged at the tops of the lower flanges 12 of the two adjacent H-shaped steel frames 1, the reinforcing chord 5 is arranged at the bottom of the upper flange 11 of the H-shaped steel frame 1, and the lower chord 2 and the lower flange 12, the reinforcing chord 5 and the upper flange 11 are connected through large hexagonal self-tapping screws. Every department of self-tapping screw quantity is no less than 2, when the 12 wall thicknesses of the lower flange of H shaped steel frame 1 is greater than 6mm, need at self-tapping screw and the 1 edge of a wing junction position of H shaped steel frame, prefabricate the hole on the edge of a wing in advance, the hole diameter is greater than big hexagonal self-tapping screw thread diameter 1 mm.
The reinforcing chord 5 is connected with one end of the lower chord 2 close to the H-shaped steel frame 1 through the side web member 4. The edge web member 4 connects the reinforcing chord member 5 with the lower chord member 2 through a round head washer self-drilling screw, so that the rigidity of the end variable-section is increased.
The side web members 4 are tightly attached to the H-shaped steel frame 1. The side web members 4 are tightly attached to the H-shaped steel frame 1, so that the vertical stress of the steel truss girder can be transferred to the H-shaped steel frame 1.
