Embodiment Construction
[0020] The present invention will be described in detail below in conjunction with the accompanying drawings.
[0021] in such as Figure 1~5 middle:
[0022] 1-Cold-formed thin-walled steel rectangular tube 1
[0023] 2-Cold-formed thin-walled steel rectangular tube 2
[0024] 3- Hot-rolled H-beam
[0025] 4-Long screw connector
[0026] Such as Figure 1 to Figure 3 As shown, the anti-buckling energy-dissipating support is composed of two cold-formed thin-walled steel rectangular tubes 1-2 and a core hot-rolled H-shaped steel 3. Two cold-formed thin-walled steel rectangular tubes 1 to 2 are buckled and pressed on both sides of the web of the hot-rolled H-shaped steel 3 through a long screw connector 4, thereby forming a peripheral restraining member. If concrete is poured into the cold-formed thin-walled steel rectangular pipe 1 and the cold-formed thin-walled steel rectangular pipe 2, the bearing capacity and rigidity of the peripheral constraints can be greatly impro...
