Stainless steel thin pipe built-in function-recoverable steel structure recycled concrete circular section column
The invention discloses a stainless steel thin pipe built-in function recoverable steel structure recycled concrete circular section column which can be used for a bottom area of a building column and a pier column in a salt mist environment. A thin stainless round pipe welded with an annular rib plate is arranged on the periphery of the section of the column, a steel reinforcement cage is arranged in a cavity of the stainless round pipe, a space truss formed by welding four steel pipe ultrahigh-strength concrete vertical rods and H-shaped steel inclined rods is arranged in the steel reinforcement cage, and studs are not welded within the range of 5 times of the diameter of the vertical rods at the bottoms of the steel pipes of the vertical rods of the space truss. The strain of the vertical rods in the range is almost equal under the action of repeated earthquakes, the steel truss vertical rods are in a deformation recoverable elastic state, and the defect that the steel truss vertical rods with the section yield due to the maximum bending moment of the bottom section of the column is overcome. The stainless steel pipes with the annular ribs and the reinforcement cage have double restraining effects on the recycled concrete and the steel truss. The column disclosed by the invention has the comprehensive technical advantages of chloride ion corrosion resistance, utilization of ecological concrete, high-efficiency stress, recoverable function after earthquake and good durability.
本发明公开了不锈钢薄管内置功能可恢复钢构再生混凝土圆截面柱，可用于盐雾环境下建筑柱子的底部区域及桥墩柱。柱子截面外围为焊接环形肋板的薄不锈圆管，不锈圆管腔体内设置钢筋笼，钢筋笼内设置由4根钢管超高强混凝土竖杆和H型钢斜杆焊接而成的空间桁架，仅在空间桁架竖杆钢管底部5倍竖杆直径范围不焊接栓钉，反复地震作用下该范围的竖杆应变近乎相等，钢构桁架竖杆处于变形可恢复的弹性状态，克服了由于柱子底部截面弯矩最大致使该截面钢构桁架竖杆屈服的弊端。带环肋的不锈钢管与钢筋笼对再生混凝土和钢构桁架具有双重约束作用。本发明的柱具有抗氯离子腐蚀、利用生态混凝土、高效受力、震后功能可恢复、耐久性好的综合技术优势。
