Detailed description of the invention
For making the purpose of this utility model, technical scheme and advantage clearly understand, below by specific embodiment and relevant drawings, the utility model will be described in further detail.
As Fig. 1 illustrates the utility model embodiment 1, the compound Concrete-Filled Square Steel Tube coupled column of a kind of New Thin-walled, comprise rectangular steel tube 1, described rectangular steel tube 1 lumen centers position is arranged with steel pipe 2, described steel pipe 2 is round steel pipe or rectangular steel tube, is filled with Concrete (3) between described rectangular steel tube 1 internal perisporium and steel pipe 2 periphery wall in the die cavity enclosed; In steel pipe 2 is coated on by the interlayer that Concrete is formed, forms effective thermal insulation protection, improve its fire endurance, improve steel ratio simultaneously, improve shock resistance, meanwhile, adopt hollow steel pipe 2 to reduce deadweight.
In the present embodiment, described rectangular steel tube 1 is welded to enclose by the rectangular-shaped clod wash steel plate 104 that two pieces of convolutions are shaping and forms, be provided with the stiffening rib 5 of inside crankle projection in the middle part of the two side of described clod wash steel plate 104, adopt clod wash steel plate can reduce the workload of welding, ensure the quality of weld seam.
The utility model embodiment 2 as shown in Figure 2, the difference of the present embodiment and embodiment 1 is, described steel pipe 2 lumen loading has concrete B(4) to provide the bearing capacity of component.
In the present embodiment, described Concrete (3) is ordinary concrete, concrete B(4) be high-strength concrete.
As Fig. 3 illustrates the utility model embodiment 3, in the present embodiment, described rectangular steel tube 1 is welded to enclose by four blocks of tabular thin-walled steel plates 101 and forms, and every block plate 101 middle inside is all welded and is provided with longitudinal stiffener 6.
As Fig. 4 illustrates the utility model embodiment 4, the difference of the present embodiment and embodiment 4 is, described steel pipe 2 lumen loading has concrete B(4) to provide the bearing capacity of component.In the present embodiment, described Concrete (3) is ordinary concrete, concrete B(4) be high-strength concrete.
As Fig. 5 illustrates the utility model embodiment 5, described rectangular steel tube 1 is welded to enclose by four pieces of Thin-walled Straight gussets 102 and forms, and the edge of right angle steel plate 102 is provided with the right angle flanging 103 turned to the inside.
