Hollow interlayer high-strength steel pipe restrained high-strength rubber concrete combination column
The invention relates to the field of green building materials, in particular to a hollow interlayer high-strength steel pipe restrained high-strength rubber concrete combination column. The combination column comprises an outer-layer high-strength steel pipe, interlayer high-strength rubber concrete and an inner-layer high-strength steel pipe. The high-strength rubber concrete is prepared through a modification technology and grading optimization, the compressive strength of the high-strength rubber concrete is larger than 50 MPa, and the space between the outer-layer high-strength steel pipe and the inner-layer high-strength steel pipe is filled with the high-strength rubber concrete. The composite column is formed by restraining the high-strength rubber concrete through the double-layer high-strength steel pipe, the bearing capacity and rigidity are guaranteed, meanwhile, the sectional area is reduced, the usage amount of concrete is reduced, and the structural self-weight is reduced. Meanwhile, the double-layer steel pipe provides lateral constraint for the rubber concrete, and the mechanical property of the rubber concrete is further improved while it is guaranteed that the concrete has certain energy dissipation capacity. The environment problem caused by stacking of the waste tires can be effectively relieved, and new kinetic energy is provided for promoting green and healthy cyclic utilization of the waste tires.
本发明涉及绿色建筑材料领域，具体涉及一种中空夹层高强钢管约束高强橡胶混凝土组合柱。该组合柱包括外层高强钢管、夹层高强橡胶混凝土、内层高强钢管三部分组成。所述的高强橡胶混凝土是指通过改性技术、级配优化制备得到抗压强度大于50MPa的高强橡胶混凝土，填充于外层高强钢管和内层高强钢管之间。本发明采用双层高强钢管约束高强橡胶混凝土形成组合柱，确保承载力和刚度的同时减小截面面积，降低混凝土的使用量，减小了结构自重。同时双层钢管对橡胶混凝土提供侧向约束，保证混凝土具有一定耗能能力的同时进一步提高橡胶混凝土力学性能。本发明将有效缓解废旧轮胎堆积带来的环境问题，为推动废旧轮胎绿色健康循环利用提供新的动能。
