Unbonded prestressed joint structure of laminated T beam under assembled building plate and construction method
The invention discloses an unbonded prestressed joint structure of a laminated T beam under an assembled building plate and a construction method. The unbonded prestressed joint structure of the laminated T-beam under the assembled building plate comprises a PC structural column, the PC laminated T-beam, a PC laminated T-beam wing plate, unbonded prestressed steel bars, overhanging steel bars on the upper portion of the laminated T-beam, a laminated plate, laminated plate truss bars and an integral post-poured concrete surface layer. The construction process flow comprises the following stepsof a, hoisting the PC structural column on site; b, carrying out on-site hoisting construction on the PC laminated T-beam; c, grouting connection of steel bar sleeves at the post-cast section of the beam-column joint and erection of a formwork support are conducted; d, stretching and anchoring the unbonded prestressed tendons at the ends of the laminated T-beam wing plates; e, hoisting the prefabricated laminated plates on site, and connecting adjacent truss rib span beams in a welded mode; f, bonding the longitudinal steel bars on the upper portion of the laminated plates, and carrying out integrally construction a post-poured concrete surface layer; and g, dismantling the formwork and the overall support at the post-pouring section. According to the structure and the method, through prefabrication, the construction time is shortened, the construction precision can be effectively controlled, the anti-seismic effect is good, and the cost is low.
本发明公开了一种装配建筑板下叠合T梁无粘结预应力节点构造的施工方法。一种装配建筑板下叠合T梁无粘结预应力节点构造，包括：PC结构柱、PC叠合T梁、PC叠合T梁翼板、无粘结预应力钢筋、叠合T梁上部外伸钢筋、叠合板、叠合板桁架筋和整体后浇混凝土面层。施工工艺流程包括：a.PC结构柱现场吊装施工；b.PC叠合T梁现场吊装施工；c.梁柱节点后浇段处钢筋套筒灌浆连接及模板支架搭设；d.叠合T梁翼板端头无粘结预应力筋张拉与锚固；e.预制叠合板现场吊装、相邻桁架筋跨梁处焊接连接；f.叠合板上部纵向钢筋绑扎、后浇混凝土面层整体施工；g.后浇段处模板及整体支架拆除。本发明通过预制，减少了施工的时间，能够有效控制施工精度，抗震效果好，成本低。
