Construction method of free-form surface concrete thick-shell opposite-pull screw system
The invention relates to a construction method of a free-form surface concrete thick-shell opposite-pull screw system. The construction method comprises the following steps: constructing a bottom die; laying bottom-layer steel bars; opposite-pull screw holes are drilled in the bottom die; penetrating a first section of opposite-pull screw at the lower part; laying a next layer of reinforcing steel bars, and connecting a next section of opposite-pull screw rod; repeating the previous step until the top of the opposite-pull screw rod reaches the steel bar layer on the upper surface of the thick shell, and then connecting the two; covering and accurately positioning an upper surface template, and marking the position of an opposite-pull screw hole of the upper surface template; the upper surface curved surface template is removed; welding a first section of opposite-pull screw at the upper part; covering again and accurately positioning the upper surface template; connecting a second section of opposite-pull screw at the upper part; and plugging and reinforcing the opposite-pull screw holes in the upper surface. According to the construction method of the free-form surface concrete thick-shell opposite-pull screw system, the problem that opposite-pull screws of free-form surface concrete thick-shell double-side formworks cannot be constructed can be solved, it is guaranteed that the formwork supporting system has enough horizontal lateral bearing capacity, and the construction requirement is met.
本发明涉及一种自由曲面混凝土厚壳对拉螺杆体系的施工方法，包括底模施工；铺设底层钢筋；在底模上钻对拉螺杆孔洞；穿下部第一段对拉螺杆；铺设下一层钢筋，连接下一段对拉螺杆；重复上一步直至对拉螺杆顶部到达厚壳上表面钢筋层然后将两者连接；覆盖并精确定位上表面模板，标记上表面模板对拉螺杆孔洞位置；移除上表面曲面模板；焊接上部第一段对拉螺杆；再次覆盖并精确定位上表面模板；连接上部第二段对拉螺杆；封堵上表面对拉螺杆洞并加固。本发明的一种自由曲面混凝土厚壳对拉螺杆体系的施工方法，可解决自由曲面混凝土厚壳双侧模板对拉螺杆无法施工问题，保证模板支撑体系具有足够的水平侧向承载力，满足施工需求。
