Non-prestressed continuous bridge pier top continuous section structure and construction method
The embodiment of the invention discloses a non-prestressed continuous bridge pier top continuous section structure and a construction method. The non-prestressed continuous bridge pier top continuoussection structure comprises prefabricated main beams and a T-shaped cast-in-place section formed between every two adjacent prefabricated main beams; each prefabricated main beam comprises a main beam web and a flange, and the flange is arranged at the top of the main beam web; the T-shaped cast-in-place section comprises a concrete layer and a high-tensile-strength concrete layer; and rebars arelongitudinally arranged in the main beam webs and the flanges and extend into the T-shaped cast-in-place section. By means of the scheme, a T-shaped space is directly formed between every two adjacent prefabricated main beams, the T-shaped cast-in-place section can be directly poured in the T-shaped space, mold building is not needed for flange parts, manpower is saved, the pouring amount of high-tensile-strength concrete is reduced while the structural stress safety is guaranteed, the construction process of a continuous bridge is greatly simplified, materials are saved, and the constructionperiod is shortened.
本发明实施例公开了一种非预应力连续桥梁墩顶连续段结构及施工方法，其中结构包括：预制主梁和两个相邻预制主梁之间形成T型现浇段；预制主梁包括：主梁腹板、翼缘，翼缘设置在主梁腹板顶部；T型现浇段包括：混凝土层和高抗拉混凝土层；在主梁腹板和翼缘内分别纵向设有钢筋，钢筋伸入至T型现浇段。通过上述方案，两个相邻的预制主梁之间直接形成T型空间，可以直接在该T型空间内浇筑T型现浇段，针对翼缘部分不需要再进行模具搭建，节省了人力，在保证结构受力安全的同时减少了高抗拉混凝土的浇注量，极大的简化了连续桥梁的施工工序，节约材料，缩短施工周期。
