Embodiment 1
[0043] Such as figure 1 As shown, the ring plate spliced hollow interlayer concrete filled steel tube composite node of the present invention includes a square steel tube column 1, an I-shaped steel beam 2 and a beam-column connection assembly 3 connecting the two;
[0044] Such as figure 2 As shown, the four corners of the square steel pipe column are fixed with connecting corner posts 4. The cross section of the connecting corner posts is an isosceles triangle, and the corners on both sides are respectively fixed at the four corners of the inner wall of the square steel pipe column by spot welding. , the connecting corner post is provided with a vertically through T-shaped hole 5;
[0045] Such as image 3 As shown, the center of the square steel pipe column is provided with a round steel pipe column 6, and four T-shaped connecting side plates 7 are evenly distributed on the round steel pipe column, and the adjacent T-shaped connecting side plates are perpendicular to e...
Embodiment 2
[0058] Such as Figure 9 As shown, the difference between this embodiment and embodiment 1 is that in this embodiment, each group of splicing plates includes two splicing plates, one of which is the same as the standard splicing plate in embodiment 1, and the other is made of the standard splicing plate in embodiment 1. The three standard splicing plates are integrated into one to form a C-shaped splicing plate, the connecting ears at both ends are reserved, and the connecting ears of the other standard splicing plate are connected by high-strength bolts.
[0059] Since the three-in-one splicing plate can only be slid in from one direction (the direction opposite to another standard splicing plate), only one T-shaped slider in the middle can be reserved. Correspondingly, it only needs to be in the corresponding A T-shaped chute is arranged on the T-shaped connecting piece on one side, and there is no need to set a T-shaped chute on the T-shaped connecting pieces on the other t...
Embodiment 3
[0061] Such as Figure 10 As shown, the difference between this embodiment and Embodiment 1 is that in this embodiment, each group of splicing plates includes two identical splicing plates, and each splicing plate is formed by combining two standard splicing plates in Embodiment 1. , become a semi-enclosed splicing plate, retain the connecting ears at both ends, and connect the connecting ears of two half-enclosed splicing plates through high-strength bolts.
[0062] The two-in-one splicing plate can be slid in from one of two directions, so one of the original two T-shaped sliders on each splicing plate can be retained, and the other can be removed. The T-shaped chute on the connecting piece is reserved, and there is no need to set the T-shaped chute on the other T-shaped connecting pieces. The semi-enclosed splicing panels are also prefabricated in advance in the factory as standard parts, and can be assembled on site. Others are the same as in Example 1.
