High-strength composite beam bridge structure and high-strength composite beam bridge structure construction method
The invention discloses a high-strength composite beam bridge structure and a construction method of the high-strength composite beam bridge structure. At a joint between a first high-strength composite beam and a second high-strength composite beam, one first transverse reserved reinforcing steel bar, a second transverse reserved reinforcing steel bar and the other first transverse reserved reinforcing steel bar are fixedly connected in sequence through connecting pieces; by means of the arrangement, pulling force generated by the two first transverse reserved steel bars on the two sides of the connecting piece and pulling force generated by the second transverse reserved steel bar in the middle of the connecting piece can be balanced, and the influence of eccentricity is avoided; meanwhile, a single connecting piece is only connected with two first transverse reserved steel bars and one second transverse reserved steel bar, the length is small, the ultra-high performance concrete can be condensed in gaps among the multiple connecting pieces, and the coherence of the ultra-high performance concrete at the joints after the ultra-high performance concrete is condensed cannot be affected.
本发明公开了一种高强组合梁桥结构及高强组合梁桥结构施工方法，在所述第一高强组合梁和所述第二高强组合梁之间的接缝处，通过连接件依次将其中一根第一横向预留钢筋、第二横向预留钢筋、另一根第一横向预留钢筋相固定连接，如此设置能够使得两根第一横向预留钢筋在连接件的两侧产生的拉力、与一根第二横向预留钢筋在连接件的中部的拉力彼此平衡，避免偏心矩的影响；同时，单个连接件只连接两根第一横向预留钢筋与一根第二横向预留钢筋，长度较短，多个连接件之间的缝隙中能凝结超高性能混凝土，不会影响接缝处的超高性能混凝土凝结后的连贯性。
