Formwork-removal-free semi-fabricated anti-corrosion concrete column and connecting method thereof
The invention relates to the technical field of constructional engineering, in particular to a form-removal-free semi-fabricated anti-corrosion concrete column and a connecting method thereof.The tail end of an upper reinforcement cage and the tail end of a lower reinforcement cage of the concrete column are fixedly welded to an upper stainless steel pipe and a lower stainless steel pipe correspondingly, and the upper reinforcement cage and the upper stainless steel pipe are fixed into an upper UHPC pipe in a pouring mode; the upper reinforcement cage and the lower stainless steel pipe are fixed in the upper UHPC pipe in a pouring mode, the lower reinforcement cage and the lower stainless steel pipe are fixed in the lower UHPC pipe in a pouring mode, the upper UHPC pipe and the lower UHPC pipe are coaxially installed in the upper PVC sleeve and the lower PVC sleeve respectively, the upper PVC sleeve and the lower PVC sleeve are connected in a sleeved mode, the splicing end of the upper UHPC pipe and the splicing end of the lower UHPC pipe are of a complementary structure, the upper UHPC pipe and the lower UHPC pipe are spliced in the upper complementary structure, and a seawater sea sand concrete column is poured in the middle of the upper UHPC pipe and the middle of the lower UHPC pipe. The multiple sections of UHPC pipes are assembled and spliced to serve as a formwork of seawater and sea sand concrete, meanwhile, the ultrahigh anti-permeability performance and high strength performance of UHPC and the corrosion resistance of PVC materials are utilized, corrosion of seawater to concrete column steel bars is isolated, and the durability of a concrete structure is improved.
本发明涉及建筑工程技术领域，具体涉及一种免拆模半装配式防腐蚀混凝土柱及其连接方法，该混凝土柱的上钢筋笼、下钢筋笼的末端分别焊接固定于上不锈钢管与下不锈钢管，上钢筋笼与上不锈钢管浇筑固定于上UHPC管中，下钢筋笼与下不锈钢管浇筑固定于下UHPC管中，上UHPC管与下UHPC管分别同轴安装于上PVC套管与下PVC套管中，上PVC套管与下PVC套管套接，上UHPC管与下UHPC管的拼接端呈互补型结构且上UHPC管与下UHPC管上互补型结构相拼接，上UHPC管、下UHPC管的中部浇筑有海水海砂混凝土柱；本发明通过多段UHPC管装配拼接作为海水海砂混凝土的模板，同时利用UHPC的超高抗渗性能、高强度性能及PVC材料的防腐蚀性，隔绝海水对混凝土柱钢筋的腐蚀，提高混凝土结构的耐久性。
