Prefabricated modular bridge deck continuous device for steel simply supported girder bridge and pier top seamless construction method
The invention relates to a prefabricated modular bridge deck continuous device for a steel simply supported girder bridge and a pier top seamless construction method. The prefabricated modular bridge deck continuous device comprises L-shaped ribs, top face connecting steel plates, side face connecting steel plates, double-arch steel pipes, prestressed tendons, anchorage devices, connecting steel bars, constructional steel bars and hexagon bolts. The prestressed tendons are tensioned and prestressed between the two horizontal sides of the double-arch steel pipe at intervals and then anchored by anchorage devices; top surface connecting steel plates are welded at the front and rear ends of the double-arch steel pipe, and connecting steel bars are welded on the side surfaces; the double-arch steel pipe is arranged on the cement mortar leveling layer on the upper surface of the main beam and is transversely spliced with the hexagon bolt through the top face connecting steel plate and the side face connecting steel plate. The double-arch structure has the beneficial effects that the double-arch structure is adopted at the beam seam, when the upper portion of the main beam is pulled and deformed, the upper portion of the double-arch steel pipe can be better pressed through the double-arch structure, the safety coefficient of the double-arch structure is greatly increased compared with that of a single-arch structure, and the deformation influence caused by temperature stress can be better resisted.
本发明涉及一种钢简支梁桥预制模块化桥面连续装置及墩顶无缝化施工方法，包括：L型肋、顶面连接钢板、侧面连接钢板、双拱钢管、预应力筋、锚具、连接钢筋、构造钢筋和六角螺栓；预应力筋每隔一段距离在双拱钢管水平两侧之间张拉预应力后用锚具锚固；双拱钢管的前后两端焊接有顶面连接钢板并在侧面焊接有连接钢筋；双拱钢管置于主梁上表面的水泥砂浆找平层上，横向通过顶面连接钢板、侧面连接钢板与六角螺栓拼接。本发明的有益效果是：本发明在梁缝处采用双拱结构，在主梁上部受拉变形时双拱构造能更好的使双拱钢管上部受压，并且双拱结构的安全系数较单拱结构大大增加，更能抵抗由温度应力带来的变形影响。
