Reinforced concrete composite column and construction method thereof
The invention provides a reinforced concrete composite column and a construction method thereof. The composite column comprises a concrete canvas layer, a fiber-reinforced material cloth layer and a PVC (polyvinyl chloride) pipe, wherein the concrete canvas layer is sheathed out of the fiber-reinforced material cloth layer; the outer part of the PVC pipe is sheathed in the fiber-reinforced material cloth layer; a concrete column core is poured in the PVC pipe; plural longitudinal stress ribs and a lateral stirrup are embedded in the concrete column core; the concrete canvas layer comprises canvas, cement powders and short fibers; the canvas is three-dimensional fabric cloth; and the cement powders and the short fibers are evenly distributed in the three-dimensional structure of the canvas.Core concrete in the composite column disclosed by the invention is under a three-dimensional pressed state so as to improve the bearing performance and the ductility performance of the concrete column, the anti-seismic property of the reinforced concrete composite column is obviously reinforced, and meanwhile, the coated improved concrete canvas can improve the high temperature resistance of thecomposite column.
本发明提供一种钢筋混凝土组合柱及其施工方法，所述组合柱包括混凝土帆布层、纤维增强材料布层及PVC管，所述混凝土帆布层套设在纤维增强材料布层外部，所述PVC管外部套设在纤维增强材料布层内部，所述PVC管内部浇筑有混凝土柱芯，所述混凝土柱芯内埋设有复数纵向受力筋以及横向箍筋；所述混凝土帆布层包括帆布、水泥粉以及短纤维；所述帆布为三维织物布，所述水泥粉和短纤维均匀分布在在所述帆布的三维结构内。本发明的组合柱内部核心混凝土呈三向受压状态，从而提高了混凝土柱的承载性能和延性性能，其抗震性能也显著增强，同时包裹的改进型混凝土帆布能够提高组合柱的耐高温性。
