Combined steel pipe support with replaceable energy consumption section
The invention discloses a combined steel pipe support with a replaceable energy consumption section. The combined steel pipe support comprises a gusset plate, end plates, an elastic support section, abuckling energy consumption section and stiffening rib plates, wherein the elastic support section comprises outer steel pipes and filled fine aggregate concrete; an inner steel pipe is arranged in an inner cavity at one end of each outer steel pipe; a flange plate is welded at one end of each inner steel pipe to form flange connection; the outer steel pipes and the inner steel pipes are welded together through the stiffening rib plates; the buckling energy consumption section comprises a buckling energy consumption steel pipe which is made of soft steel or Q235 steel with high ductility; theother ends of the outer steel pipes are connected with the end plates; the gusset plate is connected with the end plates through welding seams. According to the support, low-yield-point steel with high ductility is taken as the buckling energy consumption section, so that the support is stable in performance, easy to machine and low in manufacturing cost; and the elastic support section and the buckling energy consumption section are connected through a flange, and the buckling energy consumption steel pipe can be replaced at any time after being deformed under the action of accidental loadssuch as earthquake, so that the repair cost can be reduced, time can be saved, and the efficiency can be increased.
本发明公开一种耗能段可更换的组合钢管支撑，包括节点板、端板、弹性支撑段、屈曲耗能段和加劲肋板，弹性支撑段包括外钢管和内填细骨料混凝土。外钢管的一端内腔设置有内钢管，内钢管一端焊接有法兰盘做成法兰连接。外钢管与内钢管之间通过加劲肋板焊接在一起；屈曲耗能段包括屈曲耗能钢管，它采用延性较好的软钢或Q235钢。外钢管的另一端均连接有端板，节点板与端板通过焊缝连接；该支撑采用塑性较好的低屈服点钢作为屈曲耗能段，不但性能稳定，而且加工简单，造价低；弹性支撑段和屈曲耗能段之间使用法兰连接，在经过地震等偶然荷载作用屈曲耗能钢管变形后可随时更换，能够减少修复费用，节省时间，提升效率。
