Steel-UHPC combined formwork core-filled concrete pier column and construction method thereof
The invention provides a steel-UHPC combined formwork core-filled concrete pier column and a construction method thereof. A combined formwork comprises a UHPC outer shell and a steel plate inner shell which are formed by pouring from outside to inside in sequence. The UHPC shell is arranged on the outer layer, and the concrete column is protected by exerting the characteristic of high durability of materials; the steel plate inner shell comprises a steel plate, short shear nails and stiffening ribs, the short shear nails are welded to the outer side of the steel plate so as to enhance the connectivity with the UHPC outer shell, and the stiffening ribs are welded to the inner side of the steel plate so as to improve the overall rigidity of the combined formwork. The steel plate inner shell replaces a traditional column body steel reinforcement framework, the problem that the steel reinforcement framework is complex to hoist and position in the construction process is solved, and the construction efficiency and quality are effectively improved. The steel plate inner shell and the UHPC outer shell are prefabricated together, so that the durability of the column shell and the steel-UHPC combined formwork core-filled concrete pier column is improved; the combined formwork is tightly connected with the filling core, the radial restraining effect on the inner-layer concrete column is fully achieved, and the bearing capacity and the shock resistance of the steel-UHPC combined formwork core-filling concrete pier column are improved.
本申请提供一种钢‑UHPC组合模壳填芯混凝土墩柱及其施工方法，其组合模壳包括由外至内依次浇筑而成的UHPC外壳和钢板内壳；UHPC外壳置于外层，发挥材料自身高耐久性特点以保护混凝土柱；钢板内壳包括钢板、短剪力钉及加劲肋，短剪力钉焊接在钢板外侧，以增强与UHPC外壳的连接性，加劲肋焊接在钢板内侧，以提高组合模壳的整体刚度。钢板内壳替代传统柱身钢筋骨架，解决了施工过程中钢筋骨架吊装及定位复杂的问题，有效提升施工效率与质量；钢板内壳与UHPC外壳共同预制，提升柱壳及钢‑UHPC组合模壳填芯混凝土墩柱的耐久性；组合模壳与填芯紧密连接，充分发挥对内层混凝土柱的径向约束作用，提升钢‑UHPC组合模壳填芯混凝土墩柱承载能力与抗震能力。
