Anti-explosion hollow steel pipe-concrete composite structure column and auxiliary supporting system thereof
The invention discloses an anti-explosion hollow steel pipe-concrete composite structure column and an auxiliary supporting system thereof, and relates to the technical field of hollow supporting structures. Comprising a hollow steel pipe, an energy-absorbing material layer is arranged on the outer side of the hollow steel pipe, and the energy-absorbing material layer is of a foamed aluminum structure with an annular section; and the octagonal reinforcement cage comprises second longitudinal steel bars and second stirrups, the second stirrups are fixed to the outer sides of the second longitudinal steel bars, and the octagonal reinforcement cage is located on the outer side of the energy absorption material layer. According to the invention, through the characteristic of high rigidity of the polyvinyl alcohol-basalt hybrid fiber cement-based composite material and the characteristic of energy absorption of the annular section foamed aluminum, the composite material layer and the energy absorption material layer are in surface-to-surface contact, so that the overall effect between the two materials is enhanced; if explosion occurs, the structure can well absorb the energy of explosion impact load, reduce explosion damage, increase the anti-explosion performance of the combined structure column to the maximum extent, and improve the bearing capacity of the combined structure column.
本发明公开了一种抗爆中空钢管‑混凝土组合结构柱及其辅助支撑系统，涉及中空式支撑结构技术领域；包括：中空钢管，所述中空钢管的外侧设置有吸能材料层，吸能材料层采用圆环形截面泡沫铝结构；八角钢筋笼，八角钢筋笼包括第二纵向钢筋和第二箍筋，第二箍筋固定于各第二纵向钢筋的外侧，八角钢筋笼位于吸能材料层的外侧。本发明通过聚乙烯醇‑玄武岩混杂纤维水泥基复合材料的刚度大的特性，以及圆环形截面泡沫铝吸能的特性，复合材料层和吸能材料层相互之间面面接触，增加了两种材料之间的整体作用；若发生爆炸时，该结构能够很好的吸收爆炸冲击荷载的能量，减小爆炸损伤，最大限度上增加组合结构柱的抗爆性能，提高其承载能力。
