Unilateral curved surface formwork splicing reinforcing system and construction method
The invention discloses a unilateral curved surface formwork splicing and reinforcing system which comprises a formwork frame arranged at the preset position of an outer vertical curved surface reinforcing section of a building, and the formwork frame is formed by splicing a plurality of prefabricated formworks around the outer vertical curved surface reinforcing section of the building. A plurality of high-strength lead screws extending outwards are arranged on the building outer vertical curved surface reinforcing section in the radial direction of the building in a surrounding mode, and positioning holes connected and matched with the high-strength lead screws are formed in the formwork. The free end of the high-strength lead screw penetrates through a positioning hole in the formwork and then is fixedly connected with an opposite-pulling assembly arranged on the outer side of the formwork to form an opposite-pulling structure. The invention further comprises a construction method for the single-side curved surface formwork splicing and reinforcing system. According to the method, high-strength lead screw bar planting is converted into equivalent old wall lead screw reinforcement, meanwhile, annular hoop reinforcement is adopted, and the problems that a chimney and other circular-truncated-cone-shaped structure formwork is difficult to reinforce, prone to formwork explosion, poor in forming quality and the like can be effectively solved.
本发明公开了一种单侧曲面模板拼接加固体系，包括设置在构筑物外立曲面加固段预设位置处的模板框架，所述模板框架由若干块预制的模板环绕构筑物外立曲面加固段拼接形成，所述构筑物外立曲面加固段上沿构筑物的径向环绕设置有向外延伸的若干根高强丝杆，所述模板上设置有与所述高强丝杆连接配合的定位孔，所述高强丝杆的自由端穿过所述模板上的定位孔后与设置在模板外侧的对拉组件连接固定形成对拉结构；本发明还包括一种用于单侧曲面模板拼接加固体系的施工方法；本发明中利用高强丝杆植筋转换为等效“老墙丝杆”加固、同时采用环形抱箍加固，能有效解决了烟囱等圆台型构筑物模板加固难、易爆模，成型质量差等问题。
