Large-span UHPC (Ultra High Performance Concrete) stand construction method
The invention relates to a large-span UHPC (Ultra High Performance Concrete) stand construction method, which comprises the following steps of: building a three-dimensional sketch model through CAD (Computer Aided Design), and deepening the design on the basis of the three-dimensional sketch model; measuring and setting out; a steel bar project, a formwork supporting frame and a formwork are erected according to the drawing; preparing and transferring UHPC (Ultra High Performance Concrete); the UHPC ultra-high performance concrete is detected, poured, vibrated, cured and demolded, the tensile strength and compressive strength of the UHPC ultra-high performance concrete are far higher than those of traditional concrete, the UHPC ultra-high performance concrete can bear larger pressure and load, the service life of a building and a structure is effectively prolonged, and the UHPC ultra-high performance concrete has lower permeability and can be used for building construction. The invasion of chloride ions and other harmful substances can be effectively prevented, and the durability of the structure is improved; compared with the prior art, the building block has better toughness, improves the anti-seismic property of the structure, is more environment-friendly in the production process, effectively reduces the pollution of building wastes to the environment, is smooth in surface and free of cracks, has extremely high aesthetic degree, and can be suitable for large-span building construction.
本发明涉及一种大跨度UHPC看台施工方法，包括如下步骤：通过CAD进行三维草图模型搭建，以三维草图模型为基础，深化设计；测量放线；按图纸进行钢筋工程、模板支撑架以及模板搭设；UHPC超高性能混凝土制备及转运；UHPC超高性能混凝土检测、浇筑、振捣、养护以及拆模，UHPC超高性能混凝土的抗拉强度和抗压强度远高于传统混凝土，能够承受更大的压力和负荷，有效提高了建筑物的和结构的使用寿命，具有更低的渗透性，能够有效防止氯离子和其他有害物质的侵入，提高了结构的耐久性；具有更好的韧性，提高了结构的抗震性能，并且生产过程更加环保，有效减少了建筑废弃物的对环境的污染，表面光洁，无裂缝，具有极高的美观度，且能够适用于大跨度建筑物施工。
