FRP anti-sliding composite pipe restrained seawater and sea sand concrete column and construction method
The invention discloses an FRP anti-sliding composite pipe confined seawater and sea sand concrete column and a construction method. The FRP anti-sliding composite pipe confined seawater and sea sand concrete column structurally comprises a steel member; the FRP pipe is wound on the outer wall surface of the steel member; the ultra-high performance concrete shell is poured on the inner wall surface of the steel member; and the seawater and sea sand concrete body is poured in the ultra-high performance concrete shell. The construction method comprises the following construction steps: S1, prefabricating the steel member; s2, an FRP pipe is manufactured; s3, an ultra-high performance concrete shell is manufactured; and S4, a seawater and sea sand concrete body is manufactured. The structural design of the FRP composite pipe can be achieved, on the basis that the insufficient ductility of a single FRP confined concrete member is effectively relieved, the interface performance of seawater and sea sand concrete and the FRP composite pipe is improved, the construction efficiency is improved, meanwhile, the use performance of the composite pipe is improved, and the application range of the member is widened.
本发明公开一种FRP抗滑移复合管约束海水海砂混凝土柱及施工方法，其结构包括，钢构件；FRP管，缠绕在钢构件外壁面；超高性能混凝土壳，浇筑在钢构件内壁面；海水海砂混凝土体，浇筑在超高性能混凝土壳内。其施工步骤包括S1、预制钢构件；S2、制作FRP管；S3、制作超高性能混凝土壳；S4、制作海水海砂混凝土体。本发明能够实现对FRP复合管的结构设计，在有效缓解单一FRP约束混凝土构件延性不足的基础上，改善海水海砂混凝土与FRP复合管界面性能，提高施工效率，同时提高复合管的使用性能和扩大构件的应用范围。
