Large-span prestressed UHPC (Ultra High Performance Concrete) steel truss laminated slab and construction method thereof
The invention discloses a large-span prestress UHPC steel truss laminated slab and a construction method thereof, and relates to the technical field of fabricated building structures, the large-span prestress UHPC steel truss laminated slab comprises a UHPC bottom plate, a prestress steel bar layer arranged in the longitudinal direction of the UHPC bottom plate, a constructional steel bar layer arranged in the transverse direction of the UHPC bottom plate, and a steel bar truss layer arranged perpendicular to the constructional steel bar layer; the steel bar truss layer is located above the prestressed steel bar layer, and the prestressed steel bar layer, the constructional steel bar layer, the steel bar truss layer and the UHPC bottom plate are poured together. According to the large-span prestress UHPC steel truss laminated slab, the UHPC material serves as the formwork base body, concrete is directly cast in place on the formwork base body after installation, the structural layer is jointly formed by the formwork base body and the cast-in-place layer after forming, compared with the overall cast-in-place technology, the construction process of large-span structural steel bar binding is simplified, early-stage erecting of a scaffold is omitted, and the construction efficiency is improved. The construction efficiency is high, and the construction period is short; the requirement for the assembly rate is met, a large amount of labor and material cost is saved, and environmental protection is achieved.
本发明公开一种大跨预应力UHPC钢桁架叠合板及其施工方法，涉及装配式建筑结构技术领域，包括UHPC底板，沿UHPC底板的纵向设置预应力钢筋层，沿UHPC底板的横向设置构造钢筋层，同时垂直于构造钢筋层设置有钢筋桁架层，且钢筋桁架层位于预应力钢筋层上方，预应力钢筋层、构造钢筋层、钢筋桁架层与UHPC底板浇筑在一起。本发明中的大跨预应力UHPC钢桁架叠合板，以UHPC材料作为模板基体，安装后直接在上方现浇混凝土，成型后与现浇层一起共同形成结构层，相比于整体现浇技术，简化了大跨结构钢筋绑扎的施工流程，免除了脚手架的前期搭设，施工效率高、工期短的优势；满足装配率的要求，节省了大量人工、材料成本且更环保。
