Butt-joint construction method for prefabricated segmented pile reinforcement cage
The invention provides a prefabricated segmented pile reinforcement cage butt joint construction method, which belongs to the technical field of pile construction, and comprises the following steps: arranging, pre-assembling and segmenting reinforcing steel bars forming a pile reinforcement cage to obtain segmented reinforcing steel bars for manufacturing the segmented pile reinforcement cage; the butt joint ends of the segmented steel bars are subjected to threading treatment, and the segmented steel bars with threads are obtained; the lower butt joint ends of the segmented reinforcing steel bars with the threads are sleeved with prefabricated sleeves matched with the threads, and segmented butt joint reinforcing steel bars are obtained; the segmented butt-joint steel bars are welded to form a prefabricated segmented pile steel bar cage after being arranged and spliced; and on the construction site, the adjacent sections of prefabricated segmented pile reinforcement cages are in butt joint through the prefabricated sleeves and the threads of the butt joint ends. The method can solve the problems that in the prior art, the efficiency is low, the construction period is long, and the method cannot be suitable for the reinforcement cage with the reinforcement diameter larger than 25 mm due to the facts that welding difficulty is large, and quality is difficult to guarantee when the segmented reinforcement cage is spliced in a lap joint welding mode on the construction site.
本发明提供一种预制分段桩钢筋笼对接施工方法，属于桩柱施工技术领域，包括如下步骤：对组成桩钢筋笼的钢筋进行排布预拼装分段处理，得到用于制作分段桩钢筋笼的分段钢筋；对分段钢筋的对接端进行车丝处理，得到带螺纹分段钢筋；在带螺纹分段钢筋的下对接端套接与螺纹相匹配的预制套筒，得到分段对接钢筋；将分段对接钢筋排布拼装后焊接形成预制分段桩钢筋笼；在施工现场，将相邻段的预制分段桩钢筋笼通过预制套筒与对接端的螺纹进行对接连接。本发明能够解决现有技术中，在施工现场采用搭接焊接的方式对分段的钢筋笼进行拼装存在效率低、工期长、以及由于焊接难度大、质量难以保证等原因无法适用于钢筋直径大于25mm的钢筋笼等问题。
