Embodiment 1

[0037] This embodiment discloses an integrated cold-formed thin-walled steel plate-constrained shaped steel special-shaped column, which includes a cold-formed thin-walled special-shaped steel pipe column 1 and a built-in cold-formed thin-walled steel member 2 .

[0038] The cold-formed thin-wall special-shaped steel pipe column 1 is a cold-formed special-shaped hollow steel pipe. The overall cross-section of the cold-formed thin-walled special-shaped steel pipe column 1 is L-shaped, T-shaped or cross-shaped.

[0039] The cold-formed thin-wall special-shaped steel pipe column 1 with L-shaped cross-section as a whole includes an L-shaped core side plate 101 and two trough-shaped column legs 102 . The L-shaped core side plate 101 is L-shaped steel as a whole. The channel-shaped column limb 102 is a channel-shaped section steel as a whole. The channel section includes a web and two flange plates. The flange plate is a bent corrugated plate. The flange plate includes a plurali...

Embodiment 2

[0045] This embodiment discloses an integrated cold-formed thin-walled steel plate-constrained shaped steel special-shaped column, which includes a cold-formed thin-walled special-shaped steel pipe column 1 and a built-in cold-formed thin-walled steel member 2 .

[0046] The cold-formed thin-wall special-shaped steel pipe column 1 is a cold-formed special-shaped hollow steel pipe. The overall cross-section of the cold-formed thin-walled special-shaped steel pipe column 1 is L-shaped, T-shaped or cross-shaped.

[0047] see figure 2 A cold-formed thin-walled special-shaped steel pipe column 1 with an overall L-shaped cross section includes an L-shaped core side plate 101 and two trough-shaped column legs 102 . The L-shaped core side plate 101 is L-shaped steel as a whole. The channel-shaped column limb 102 is a channel-shaped section steel as a whole. The channel section includes a web and two flange plates. The flange plate is a bent corrugated plate. The flange plate inc...

Embodiment 3

[0053] see Figure 8 with Figure 9 , this embodiment provides a thin-walled steel structure residential system using the above-mentioned integrated cold-formed thin-walled steel plate constrained profiled steel special-shaped column. The integrated cold-formed thin-walled steel plate constrained shaped steel special-shaped column is welded to the cold-formed thin-walled composite beam 4. The floor keel 5 and the cold-formed thin-walled composite beam 4 are connected by self-tapping screws. The upper integrated cold-formed thin-walled steel plate constrained profiled steel special-shaped column and the lower integrated cold-formed thin-walled steel plate constrained profiled steel profiled column can be butted together. Tap screw connections. The integrated cold-formed thin-walled steel plate constrained steel special-shaped column is used for load-bearing and lateral resistance. The space layout is flexible, and it is easy to form a large space. The indoor structural compo...

Abstract

The invention provides an integrated cold-formed thin-walled steel plate constraint profile steel special-shaped column and a machining method thereof. The special-shaped column comprises a cold-formed thin-walled special-shaped steel pipe column and a built-in cold-formed thin-walled steel member; the cold-formed thin-walled special-shaped steel pipe column is a special-shaped hollow steel pipe formed by cold bending; the cross section of the cold-formed thin-walled special-shaped steel pipe column is integrally L-shaped, T-shaped or cross-shaped; the built-in cold-formed thin-walled steel member is embedded and inserted in a notch of a groove-shaped column limb; and the built-in cold-formed thin-walled steel member is connected with the straight supporting surface through a self-tapping screw. The integrated cold-formed thin-walled steel plate constraint profile steel special-shaped column is adopted as a vertical bearing component, indoor column protruding can be avoided, and the building use function and attractiveness requirements are met. The width-to-thickness ratio of the section of the special-shaped steel pipe column is large, local buckling is prone to occurring, and the situation that the bearing capacity is reduced due to local buckling of a plate can be avoided through the built-in cold-formed thin-walled steel member.

Description

technical field [0001] The invention relates, in particular, to an integrated cold-formed thin-walled steel plate constrained profiled steel special-shaped column and a processing method thereof. Background technique [0002] Building energy consumption has become an important part of my country's total social energy consumption. Statistics show that in 2014, building energy consumption accounted for about 30% of the total social energy consumption. The proportion will reach 46% to 47%. It can be seen that the energy consumption and resource waste of construction projects in my country are very serious at present, and the overall energy consumption of the industry is high. Cold-formed thin-walled houses have the characteristics of low steel consumption, recyclable steel, low self-weight, less labor input, short construction period, high degree of prefabrication, and good seismic performance. Therefore, cold-formed thin-walled steel structure houses The popularization and use...
