一种部分组合预制柱的拼接方法
摘要：
本发明涉及一种部分组合预制柱的拼接方法，其包括如下工艺步骤：1)，预制H型钢‑混凝土部分组合柱；2)，部分组合预制柱在搭接区预先不灌混凝土，在搭接区的腹板上开螺栓孔；3)，拼接的预制柱中的纵筋伸出各自的中间区至搭接区，但拼接柱伸出的纵筋留有一段距离d；4)，拼接的两根柱在搭接区进行栓焊连接；5)，在搭接区，采用搭接钢筋与拼接柱中的纵筋焊接连接；6)，在完成上述2～5后，在搭接区灌注混凝土。本发明的部分组合预制柱的拼接方法具有施工方便，拼接牢固等诸多有点，填补了国内在部分组合柱柱柱拼接方面的空白。
摘要（英）：

The invention relates to a splicing method for partial composite prefabricated columns. The splicing method comprises the following technological steps that (1), the H-shaped steel-concrete partial composite columns are prefabricated; (2), concrete is not poured in the partial composite columns at a lap joint area in advance, and bolt holes are formed in webs of the lap joint area; (3), longitudinal bars in the spliced prefabricated columns stretch out of respective intermediate areas to the lap joint area, but sections of distances d are left on the stretch-out longitudinal bars of the spliced columns; (4), the two sliced columns are subjected to bolt-welding connection in the lap joint area; (5), in the lap joint area, lap joint steel bars are adopted to be connected with the longitudinal bars in the spliced columns in a welding mode; and (6), after the steps from the step (2) to the step (5) are completed, the concrete is poured in the lap joint area. The splicing method for the partial composite prefabricated columns has the multiple advantages that construction is convenient and splicing is firm, and the domestic blank in partial composite column splicing is filled.
