Embodiment 1
[0050] The size of the rectangular concrete filled steel tube column 2 in this embodiment is 1000*1500, the wall thickness is 30mm, and the column height is 6000mm. The inner partition ring plate 3 material adopts Q235B, and the vent hole 31 is an isosceles right-angled triangle whose right angle side length is 50mm, and the vent hole 31 is opened on four corners of the inner partition ring plate 3 .
[0051] The upper and lower spacing of the inner partition ring plate 3:
[0052] The quantity q=6000 / 1125≈5 (pieces) of the inner partition ring plate 3
[0053] Inner partition ring plate 3 thickness:
[0054] Take 6mm.
[0055] By adding 5 layers of inner partition ring plate 3 in the steel pipe column, the inner partition ring plate 3 is integrated with the steel pipe column and the concrete after pouring concrete, and the multi-layer inner partition ring plate 3 exerts lateral restraint on the side wall of the steel pipe column to prevent The side wall of the steel pi...
Embodiment 2
[0057] The size of the rectangular concrete-filled steel tube column 2 in this embodiment is 1500×1500, the wall thickness is 35 mm, and the column height is 5400 mm. The material of the inner partition ring plate 3 is Q235B, and the vent hole 31 is an isosceles right triangle with a right angle side length of 50 mm.
[0058] The upper and lower spacing of the inner partition ring plate 3:
[0059] The quantity q=5400 / 1985≈3 (pieces) of the inner partition ring plate 3
[0060] Inner partition ring plate 3 thickness:
[0061] Take 8mm thick.
[0062] By adding three layers of inner partition ring plates 3 in the steel pipe column, the inner partition ring plate 3 is integrated with the steel pipe column and the concrete after pouring concrete, and the multi-layer inner partition ring plate 3 exerts lateral restraint on the side wall of the steel pipe column to prevent The side wall of the steel pipe column is hollow.
