[0023] Example
[0024] See Figure 1 ~ 4 As shown, the present invention provides a reflexed steel structural main beam connection node, including the main beam 1 and the secondary beam 2, and the main beam 1 and the secondary beam 2 are connected by a pair of opposing fish on the belle 3. The fish belle 3 includes a vane 3a, a first flat wing 3b, a curved flap 3C, a second flat wings 3D, and the main beam 1, and the second flat wing 3D are connected to the primary beam 2.
[0025] Specifically, the lampping of the lamelling point of the general beam node is extremely susceptible to buckling, and the present application uses no hanging-side connection to connect the main beam and the secondary beam through a anti-flexible fish belle structure. Shear, can avoid the material loss brought by the secondary beam cutting mouth in the traditional design, and the flexural damage caused by the subsidence of the secondary beam. The configuration cross section of the two fish belle 3 has sym...
