Prefabricated concrete square pile connecting method based on H-shaped steel rear insertion method
The invention discloses a prefabricated concrete square pile connecting method based on an I-shaped steel rear insertion method. Firstly, four steel embedded parts with semi-I-shaped slotted holes are embedded in the end of a prefabricated concrete square pile, one ends of the semi-I-shaped slotted holes are opened in the direction of the slotted holes, the other ends of the semi-I-shaped slotted holes are closed, the opened ends of the semi-I-shaped slotted holes face outwards, the four steel embedded parts are connected end to end to form a square-ring-shaped connecting piece, and meanwhile the steel embedded parts are welded to prefabricated square pile main reinforcements. During construction, the precast concrete square pile at the upper part is lifted to be in butt joint with the slotted hole of the concrete square pile at the lower part, and an I-shaped steel part of which the surface is coated with an adhesive is inserted into the slotted hole, so that the upper and lower piles are connected. According to the method, the welding quality defect caused by factors such as constructor quality, method and environment and the long-time cooling problem after welding in a traditional welding connection mode can be effectively improved, the slot type connection mode is adopted in the method, the connection difficulty is greatly reduced, the construction time and cost are saved, and the construction efficiency is improved. And meanwhile, the construction quality of the concrete square pile joint can be guaranteed.
本发明公开了一种基于工字形钢后插法的预制混凝土方桩连接方法。首先在预制混凝土方桩的端部预埋四个带半工字形槽孔钢制预埋件，半工字形槽孔沿槽孔走向一端开口，另一端封闭，开口一端朝外，四个钢制预埋件首尾连接形成方环形连接件，同时钢制预埋件焊接在预制方桩主筋上。施工时，将上部的预制混凝土方桩起吊与下部的混凝土方桩槽孔对接，并用表面涂有胶粘剂的工字形钢制件插入槽孔使上下方桩相连。本发明可有效改善传统焊接连接方式由于施工人员素质、方法、环境等因素造成的焊接质量缺陷以及焊接完成后长时间冷却问题，而且该方法采用插槽式的连接方式，大大降低连接难度，节约施工时间和成本，同时能够保证混凝土方桩连接处的施工质量。
