Restraint bonding double-reinforced UHPC shell mold FRP steel reinforced concrete column and construction method
The invention discloses a restrained and bonded double-reinforced UHPC shell mold FRP steel reinforced concrete column and a construction method, relates to the technical field of building structure engineering, and solves the problems that an existing reinforced concrete column template is low in turnover utilization rate and large in occupied amount, wastes resources and the like. The device comprises a shell film, a framework, I-shaped steel and common concrete, the shell film is in a square shape and is made of ultra-high-performance concrete, the framework is arranged in a cavity of the shell film, and the I-shaped steel is arranged in the framework; common concrete is poured in the cavity; a plurality of flanges are arranged on the inner surface of the shell mold in the vertical direction at equal intervals, and closed hoops are embedded in the flanges; and a plurality of FRP fabrics are embedded in the shell mold body. The UHPC shell mold adopted by the invention is customized in advance, cured and transported to a site to be directly spliced, so that the mounting is convenient and quick; the formwork made of UHPC is not prone to deformation in high-temperature weather construction, deformation of the formwork is small, and accuracy of the section size is guaranteed. The anti-permeability and the impact toughness are excellent, and the service life of a component can be prolonged.
本发明公开了一种约束粘结双增强UHPC壳模FRP型钢混凝土柱及施工方法，涉及建筑结构工程技术领域，解决了现有钢筋混凝土柱模板的周转利用率低、占用量大、浪费资源等问题。本发明包括包括壳膜、骨架、工字钢和普通混凝土，壳膜为口字形，材质为超高性能混凝土，壳模的空腔中设置有骨架，骨架内设置有工字钢；空腔中浇筑有普通混凝土；壳模内表面垂直方向等间距设置有若干凸缘，凸缘内部埋设有闭合箍；壳模本体内还埋设有若干FRP织物。本发明采用的UHPC壳模预先定制、养护完成，运至现场后直接进行拼装，安装方便快捷；用UHPC制作的模板高温天气施工不易变形，模板变形小，保证了截面尺寸的精确性；抗渗性和抗冲击韧性优良，可延长构件使用寿命。
