Vertical structure butt joint method of reverse construction structure
The invention discloses a vertical structure butt joint method of an inverse construction structure, which comprises the following steps of: 1, before underground structure construction, drooping a line from an inverse construction zero-layer structure, and performing secondary positioning on coordinates of a foundation slab according to the formed zero-layer structure; 2, when a small amount of horizontal deviation occurs during butt joint of the vertical structures, reinforcing steel bar binding is carried out at butt joint nodes; the upper and lower deviated wall body steel bars (11) in the deviated wall body are butted after being bent, and are deviated to increase the thickness of the wall body; a third embedded steel bar (21) is arranged between the deviation part of the column body of the zero floor slab (12) and the column body (2), and a column body steel bar (22) in the column body (2) is bent and then is in butt joint with the column body steel bar (22); and 3, erecting a template system (7) at the butt joint node, arranging a horn mouth (4) at the connection part of the template system (7) and the beam body (3), and pouring concrete at the butt joint part through the horn mouth (4). The construction quality of the butt joint node of the reverse construction structure can be improved.
本发明公开了一种逆施工结构的竖向结构对接方法，包括步骤：1、在地下结构施工前，从逆施工的零层结构向下垂线，基础底板的坐标根据已经成型的零层结构进行二次定位；2、在竖向结构对接时发生少量水平偏位时，在对接节点处进行钢筋绑扎；偏位墙体内的上、下偏位的墙体钢筋(11)弯折后对接，并偏位增加墙体的厚度；在零层楼板(12)柱体偏位部位与柱体(2)之间设置第三植筋(21)，并将柱体(2)内的柱体钢筋(22)弯折后对接；3、在对接节点处支设模板体系(7)，并在模板体系(7)与梁体(3)的接驳部位设置喇叭口(4)，通过喇叭口(4)在对接部位浇筑混凝土。本发明能提高逆施工结构的对接节点处的施工质量。
