Ocean structure engineering combination column component adopting permanent formwork and connecting method
The invention discloses an ocean structure engineering combination column component adopting a permanent formwork and a connecting method. The component comprises a permanent formwork, filled common concrete, a steel pipe, a PBL shear connector, a butt joint inner flange plate and a formwork reinforcing mesh. The adopted prefabricated ultrahigh-toughness concrete formwork can be used for structure anti-corrosion protection, and internal materials are protected against erosion damage of environmental media. The arranged shear-resistant connecting structure is convenient to manufacture and machine, it is guaranteed that internal steel pipes and peripheral concrete are cooperatively stressed and deformed, the fatigue stress amplitude of components in the service period is reduced, and the service life of the ocean platform structure is prolonged. The outer wrapped concrete layer inhibits internal steel buckling, and the steel consumption of the steel pipe is reduced. The combined column component has the advantages of being light in self weight, easy to assemble a building, high in corrosion resistance and low in fatigue stress amplitude, and is particularly suitable for ocean structure engineering.
本发明公开一种采用永久模板的海洋结构工程组合柱构件及连接方法。构件组成包括：永久模板，内填普通混凝土，钢管，PBL抗剪连接件，对接内法兰板，模板钢筋网。采用的预制超高韧性混凝土模板可以作为结构防腐蚀保护，保护内部材料不受环境介质的侵蚀损害。设置的抗剪连接构造制作加工方便，保证内部钢管和外围混凝土协同受力和变形，降低构件在服役期间的疲劳应力幅值，延长海洋平台结构的服役寿命。外包混凝土层抑制内部钢屈曲，减少钢管用钢量。组合柱构件具有自重轻、易装配化建筑、抗腐蚀能力强、疲劳应力幅值低的优点，特别适合于海洋结构工程。
