Prefabricated UHPC joint component and connecting method
The invention discloses a prefabricated UHPC joint component and a connecting method. The prefabricated UHPC joint component comprises a prefabricated UHPC joint component body, a prefabricated concrete column and a prefabricated concrete beam, wherein the prefabricated UHPC joint component body is composed of a UHPC layer, core area concrete, a U-shaped groove, a reserved hole and a reserved steel bar; the prefabricated concrete column and the prefabricated UHPC joint component body are connected through a bedding layer; the prefabricated concrete beam and the prefabricated UHPC joint component body are connected through a common concrete post-pouring section; a prefabricated concrete lower column longitudinal bar penetrates the joint component body and is fixed in a steel bar sleeve located on the bedding layer.; and a beam longitudinal bar and the reserved steel bar are connected through a steel bar sleeve at the common concrete post-pouring section. Through the prefabricated UHPC joint component, UHPC is used for the outer portion of a joint, the complex construction problem of a joint area is avoided, the structure stress performance is improved, the joint durability is enhanced, the problem that cast-in-place UHPC is difficult to maintain is solved, the material usage amount is reduced, and cost is reduced.
本发明公开一种预制UHPC节点构件及连接方法，包括预制UHPC节点构件、预制混凝土柱、预制混凝土梁；所述预制UHPC节点构件由UHPC层，核心区混凝土，U型槽，预留孔洞和预留钢筋组成；预制混凝土柱和预制UHPC节点构件通过坐浆层连接，预制混凝土梁和预制UHPC节点构件通过普通混凝土后浇段连接，预制混凝土下柱纵筋穿过节点构件，柱纵筋固定在位于坐浆层的钢筋套筒里，梁纵筋与预留钢筋在普通混凝土后浇段通过钢筋套筒连接。本发明通过预制UHPC节点构件，将UHPC用于节点外部，避免了节点区复杂的施工问题、提高结构受力性能、增强了节点耐久性、克服了现浇UHPC难养护的问题、又节省了材料的用量，降低了成本。
