Split prefabricated cover beam connected with support cushion blocks and construction method of split prefabricated cover beam
The invention discloses a split prefabricated cover beam connected with support cushion blocks and a construction method of the split prefabricated cover beam. The split prefabricated cover beam comprises two or more prefabricated split pieces evenly distributed in the longitudinal bridge direction. All the prefabricated fragments are arranged on more than two shared bridge piers in parallel at intervals, a plurality of cast-in-place support lower padstones are arranged on the prefabricated fragments in the transverse bridge direction, and the prefabricated fragments are fixedly connected through the plurality of support lower padstones; each support lower padstone is of a cast-in-place structure, and an internal steel bar structure comprises a plurality of perforated steel plates arranged in the transverse bridge direction and a plurality of perforated steel bars arranged in the longitudinal bridge direction. During construction, the prefabricated fragments are manufactured firstly, then the prefabricated fragments are arranged in place on the pier, then the perforated steel plates are sequentially arranged on the prefabricated fragments, the perforated steel bars are arranged in a penetrating mode, other constructional steel bars of the lower cushion stone of the support are bound, and finally concrete is poured to connect all the prefabricated fragments into a whole. By applying the method, the integrity of the bent cap can be improved, the hoisting construction procedure is simplified, and the construction efficiency is improved.
本发明公开了支座垫块连接的分片预制盖梁及其施工方法，包括沿纵桥向均布的两片以上预制分片；所有预制分片均设置在共用的两个以上桥墩上，互相之间平行并间隔设置，上面沿横桥向设有多个现浇的支座下垫石，通过多个支座下垫石固定连接；每一支座下垫石均为现浇结构，内部的钢筋结构均包括若干沿横桥向布置的开孔钢板，及若干沿纵桥向布置的穿孔钢筋。施工时，先制作预制分片，然后将预制分片在桥墩就位，再在预制分片上依次设置开孔钢板、穿设穿孔钢筋并绑扎支座下垫石的其它构造钢筋，最后浇筑混凝土将所有预制分片连接为一个整体。本发明的应用可提高盖梁整体性、简化吊装施工工序、提高施工效率。
