Mortise and tenon connection prefabricated small box girder type hidden cover beam and construction method thereof
The invention discloses a mortise and tenon connection prefabricated small box girder type hidden cover beam and construction method thereof. The prefabricated small box girder type hidden cover beam comprises a prefabricated small box girder, a cast-in-place hidden cover beam and a concrete mortise and tenon connecting structure, wherein the concrete mortise and tenon connecting structure can achieve splicing of the prefabricated small box girder and the cast-in-place hidden cover beam and comprises a multi-protrusion tooth block end connecting structure and a shear-resistant connecting structure system; the multi-protrusion tooth block end connecting structure comprises a female tooth structure and a cast-in-place concrete joint; the female tooth structure is arranged at an end of the prefabricated small box girder and comprises a plurality of web convex teeth arranged on the outer side of an end of a web of the small box girder; the shear-resistant connecting structure system comprises tenon concrete, PBL key steel plates, connecting steel plates, PBL key steel bars and anchoring steel bars, the PBL key steel plates, the connecting steel plates, the PBL key steel bars and the anchoring steel bars are buried in the tenon concrete. The prefabricated small box girder type hidden cover beam is advantaged in that problems of bearing capacity, deformation and durability between the prefabricated small box girder and the cast-in-place hidden cover beam are effectively solved.
本发明公开了一种榫卯连接的预制小箱梁式隐盖梁及其施工方法。预制小箱梁式隐盖梁包括预制小箱梁、现浇隐式盖梁以及混凝土榫卯连接结构，混凝土榫卯连接结构，能够实现预制小箱梁、现浇隐式盖梁的拼接，包括多突式齿块端头连接结构以及抗剪连接结构体系；多突式齿块端头连接结构包括阴齿结构以及现浇混凝土接缝；所述的阴齿结构，设置于预制小箱梁的端头，包括若干设置于小箱梁腹板端头外侧的腹板凸齿。抗剪连接结构体系包括榫头混凝土以及埋填在榫头混凝土中的PBL键钢板、连接钢板、PBL键钢筋以及锚固钢筋。本发明有效地解决了预制小箱梁与现浇隐式盖梁之间的承载力、变形及耐久性问题。
