Embodiment 1
[0023] Embodiment 1 (see figure 1 ): The present invention is a kind of cold-formed thin-walled steel center column node related to structural engineering. It consists of square steel pipe columns 1, square steel pipe beams 2, C-shaped steel beams 3, trim plates 4, fillet welds 5 and 6, and self-tapping screws 7. Two square steel pipe columns 1 connect two C-shaped steel beams 3 on both sides through eight fillet welds 5; six panels 4 are welded on the upper and lower flange surfaces of the C-shaped steel beam 3, and are distributed on the C-shaped steel beam 3 mid-span and both ends; four square steel pipe girders 2 and C-shaped steel girder 3 are welded to the lower flange of C-shaped steel girder 3 through fillet welds 6 (when the web height of C-shaped steel girder 3 exceeds the specification requirements, the The self-tapping screw 7 connects the square steel pipe column 1 with the transverse C-shaped steel beam 3). In this type of node, the C-shaped steel beam 3 is arr...
Embodiment 2
[0024] Embodiment 2 (see figure 2 , image 3 ): The present invention is a kind of cold-formed thin-walled steel side column node related to structural engineering. It consists of square steel pipe columns 1, square steel pipe beams 2, C-shaped steel beams 3, steel plates 8, trim plates 4, fillet welds 5, fillet welds 6, and self-tapping screws 7. Two square steel pipe columns 1 and a C-shaped steel beam 3 are welded on one side through four fillet welds 5, and two square steel pipe columns 1 and a steel plate 8 are welded on the other side through four fillet welds 5; the C-shaped steel beam 3 and the upper and lower surfaces of the steel plate 8 are welded with six panels 4, evenly distributed between the square steel pipe columns 1; two square steel pipe beams 2 are welded to the lower flange of the C-shaped steel beam 3 through the fillet weld 6 (when the steel plate When the height of the web plate of the C-shaped steel beam 3 exceeds the specification requirement, sel...
Embodiment 3
[0025] Embodiment 3 (see Figure 4 , Figure 5 ): The present invention is a kind of cold-formed thin-walled steel corner column joint related to structural engineering. It consists of square steel pipe columns 1, square steel pipe beams 2, C-shaped steel beams 3, steel plates 8, trim plates 4, fillet welds 5, fillet welds 6, and self-tapping screws 7. A square steel pipe column 1 and a C-shaped steel beam 3 are welded on one side through a fillet weld 5, and a square steel pipe column 1 and a steel plate 8 are welded on the other side through a fillet weld 5; the C-shaped steel beam 3 and the steel plate 8 The upper and lower surfaces are welded with panel 4, and the C-shaped steel beam 3 and the square steel pipe girder 2 are welded to the lower flange of the C-shaped steel beam 3 through the fillet weld 6 (when the height of the web of the steel plate 8 and the C-shaped steel beam 3 exceeds the specification requirements , can adopt self-tapping screw 7 to connect it with...
