FRP fabric constraint bonding double-reinforced UHPC (Ultra High Performance Concrete) shell, mold and preparation method
The invention discloses an FRP (Fiber Reinforce Plastic) fabric constraint bonding double-reinforced UHPC (Ultra High Performance Concrete) shell, a mold and a preparation method, relates to the technical field of building structure engineering, and solves the problems of low turnover utilization rate, high cost, large construction error, easiness in stripping from a component and easiness in cracking of an existing reinforced concrete column template. The device comprises a UHPC shell and a manufacturing mold, wherein the UHPC shell is provided with a spaced inner flange, and a framework and fiber fabric are embedded in the UHPC shell; the mold comprises an outer-layer steel mold plate and an inner-layer steel mold plate, the inner-layer steel mold plate comprises a mold plate I and a mold plate II, and trapezoidal grooves are equidistantly formed in the mold plate I and the mold plate II; the outer-layer steel formwork comprises two groove-shaped steel plates, and the inner-layer steel formwork is buckled in the two groove-shaped steel plates. The bonding force between the UHPC shell and the cast-in-place concrete is high, the overall performance of the composite beam is improved, and the shear bearing capacity is increased. The U-shaped shell can better resist lateral pressure through the framework and the FRP fabric, the engineering quality is guaranteed, and the cost is reduced.
本发明公开了一种FRP织物约束粘结双增强UHPC外壳、模具及制备方法，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、成本高、施工误差大、与构件容易剥离以及易开裂问题。本发明包括带间隔内凸缘并且内部埋设有骨架和纤维织物的UHPC外壳以及制造模具；模具包括外层钢模板和内层钢模板，内层钢模板包括模板一和模板二，模板一和模板二上均等距开设有梯形槽；外层钢模板包括两个槽型钢板，两个槽型钢板将内层钢模板扣合在内。本发明的UHPC外壳和现浇混凝土之间的粘结力强，提高组合梁整体性能，增大抗剪承载力。骨架和FRP织物使U型壳更好的抵抗侧压力，保证工程质量，降低成本。
