Continuous beam segment prefabricating and assembling method
The invention discloses a continuous beam segment prefabricating and assembling method. The method comprises the steps: 1, arranging a cast-in-place continuous segment at the pier top of a main pier; 2, carrying out re dividing by combining a continuous beam prestress full-length bundle anchor cable tensioning anchorage pier design; 3, dividing the prefabricated simply supported beam sections according to the prestress; 4, performing processing according to the shape and the length of the pier top continuous beam; 5, assembling the prefabricated segment hoisting equipment on the cast-in-place continuous segment; 6, performing hoisting section by section according to section arrangement; 7, hoisting the sections; and 8, measuring the strength of the concrete, penetrating and pulling an anchor cable, performing tensioning, grouting and anchoring, and completing system transformation. According to the continuous beam segment prefabricating and assembling method, traditional continuous beam cantilever pouring construction is adjusted to ground construction from high altitude, segment prefabricating of a beam body is conducted on a prefabricating field, then the beam body is transported to the field segment by segment and hoisted to a preset position in a cantilever progressive mode, and then prestress is applied to sequentially connect all segments into a whole; and finally, the mid-span wet joint is cast in place in a suspended formwork mode to complete beam body construction.
本发明公开了一种连续梁节段预制拼装方法，包括步骤1，主墩墩顶设置现浇连续段；步骤2，结合连续梁预应力通长束锚索张拉锚墩设计；步骤3，根据预应力预制简支梁节段划分；步骤4，根据墩顶连续梁体型及长度；步骤5，在现浇连续段上完成预制节段起吊设备组装；步骤6，依据节段设置，逐节段吊装；步骤7，节段吊装；步骤8，测量混凝土强度，穿拉锚索、张拉注浆锚固，完成体系转化。本发明所述连续梁节段预制拼装方法将传统连续梁悬臂浇筑施工由高空调整到地面施工，先在预制场进行梁体的节段预制，再逐段运至现场，以悬臂渐进的方式吊装至预定位置，然后施加预应力将各节段依次连接成为整体，最后以吊模的方式现浇跨中湿接缝完成梁体施工。
