Assembly type UHPC prefabricated beam column post-pouring cavity integral connecting structure and construction method
The invention provides a fabricated UHPC prefabricated beam column post-pouring cavity integral connecting structure and a construction method, and belongs to the technical field of structural engineering. The fabricated UHPC prefabricated beam column post-pouring cavity integral connecting structure comprises a cast-in-place concrete frame column, an I-shaped UHPC prefabricated frame beam and a U-shaped UHPC prefabricated frame beam; reliable connection between the I-shaped UHPC prefabricated frame beam and the cast-in-place frame column is achieved in the mode that the I-shaped UHPC prefabricated frame beam and the rectangular concrete frame column are formed through one-time simultaneous integral casting of the beam end variable cross-section transition cavity and the column core area concrete. The concrete is good in integrality, high in safety degree, excellent in mechanical property and excellent in anti-seismic property; the connection construction method is simple and feasible, the construction cost is saved, the construction period is shortened, the construction quality is guaranteed, the industrialization efficiency of the fabricated building is remarkably improved, and generalization and standardization can be achieved. Meanwhile, the UHPC new material is innovatively applied to a concrete assembly type structure system, and development of a modern assembly type structure is powerfully promoted.
提供一种装配式UHPC预制梁柱后浇空腔整体式连接结构及施工方法，属于结构工程技术领域，包括现浇混凝土框架柱、工字型UHPC预制框架梁和U型UHPC预制框架梁，工字型UHPC预制框架梁与矩形混凝土框架柱通过梁端变截面过渡空腔与柱核心区混凝土一次同时整浇成形的方式，实现了工字形UHPC预制框架梁和现浇框架柱之间的可靠连接。本发明整体性好，安全度高，力学性能优异，具有优越的抗震性能；该连接施工方法简单可行，节约施工成本，缩短施工工期，保证施工质量，显著提升装配式建筑工业化效率，并可以实现通用化，标准化。同时将UHPC新材料创新性的应用于混凝土装配式结构体系中，有力的推动了现代装配式结构的发展。
