Embodiment 1
[0044] A steel plate-steel support combination anti-lateral force member in this embodiment includes a steel plate 1 and a steel support 2 integrated with the steel plate 1. The shape of the steel plate 1 is a rectangle with two corners on the same side removed, forming a " The shape of the cut part is square. The steel support 2 includes two symmetrical parts, which are respectively placed on both sides of the steel plate 1. The cross-sectional shape of the steel support 2 composed of the two parts is rectangular. The two parts of the steel support 2 Some are channel-section steel made by cold working. Ten bolt holes 8 are equidistantly opened on the steel support 2, and the distance between the bolt holes 8 and the end of the steel support 2 is 150mm, and ten bolt holes 8 are also opened on the corresponding position of the steel plate 1, and the two parts of the steel support 2 They are respectively connected to the steel plate 1 through high-strength bolts and nuts, and hi...
Embodiment 2
[0047] The basic structure of a steel plate-steel support composite anti-lateral force member and the beam-column structure using the member in this embodiment is the same as that of embodiment 1, except that the steel support 2 includes two symmetrical parts, which are respectively placed on the steel plates On both sides of 1, the cross-sectional shape of the steel support 2 composed of the two parts is circular. 1 bolt hole 8, the distance between the bolt hole 8 and the end of the steel support 2 is 175mm, and 15 bolt holes 8 are also provided at the corresponding position of the steel plate 1, the large diameter of the high-strength bolt and nut is 14mm, and the distance between the high-strength bolts is 250mm, The material of steel plate 1 and steel support 2 is Q345. The thickness of the fish plate 3 is 2.5 times the thickness of the steel plate 1, and a corner is cut off on the gusset plate 4 and the gusset plate stiffener 7, and the size of the cut corner is 30mm.
Embodiment 3
[0049] The basic structure of a steel plate-steel support composite anti-lateral force member and the beam-column structure using the member of this embodiment is the same as that of embodiment 1, the difference is that 20 bolt holes 8 are equidistantly opened on the steel support 2 , the distance between the bolt holes 8 and the end of the steel support 2 is 200 mm, and there are 20 bolt holes 8 on the corresponding position of the steel plate 1. The material of support 2 is Q345. The thickness of the fish plate 3 is three times the thickness of the steel plate 1, and a corner is cut off on the gusset plate 4 and the gusset plate stiffener 7, and the size of the cut corner is 40mm.
[0050] In order to better understand the content of the present invention, a steel plate-steel support composite anti-lateral force component and the manufacturing process of the beam-column structure using the component are given.
[0051]To make a beam-column structure using a steel plate-stee...
