Low-shrinkage formwork-free bridge deck joint structure and construction method
The invention provides a low-shrinkage formwork-free bridge deck joint structure and a construction method. The low-shrinkage formwork-free bridge deck joint structure comprises a plurality of precastbeams, precast blocks, multiple first ring ribs and multiple second ring ribs, wherein a joint space is reserved between every two adjacent precast beams, the precast blocks are installed in the joint spaces, pouring spaces are reserved between the precast blocks and the two adjacent precast beams, the first ring ribs are installed in the precast beams, two sides of each first ring rib extend outof the precast beam, the second ring ribs are installed in the prefabricated blocks, two sides of each second ring rib extend out of the prefabricated block, and the second ring ribs and the first ring ribs are arranged in a staggered mode. The low-shrinkage formwork-free bridge deck joint structure is advantaged in that formwork-free construction is achieved, the process is simple and convenient, the joint cast-in-place amount is small, and the structure is reasonable.
本发明提供一种低收缩的免模板桥面接缝构造及施工方法。所述低收缩的免模板桥面接缝构造包括多个预制梁，两个相邻的预制梁之间预留有接缝空间；预制块，所述预制块安装在所述接缝空间内，所述预制块与相邻的两个所述预制梁之间预留有浇灌空间；多个第一环筋，所述第一环筋安装在所述预制梁内，所述第一环筋的两侧均延伸至所述预制梁外；多个第二环筋，所述第二环筋安装在所述预制块内，所述第二环筋的两侧均延伸至所述预制块外，且所述第二环筋与所述第一环筋交错设置。本发明提供的低收缩的免模板桥面接缝构造及施工方法具有施工免模板、工序简便、接缝现浇量较小、构造合理的优点。
