变截面圆形墙模板支设结构
摘要：
本实用新型涉及一种变截面圆形墙模板支设结构，包括相对设置的圆形墙内模板和圆形墙外模板、以及紧固所述圆形墙内模板和所述圆形墙外模板的对拉螺栓，所述圆形墙外模板包括支设于下部的第一外模板和支设于上部的第二外模板，所述第二外模板相对于所述第一外模板靠近所述圆形墙内模板，所述第一外模板支设于地面，所述第一外模板的顶端设有支撑杆，所述第二外模板支设于所述支撑杆上。该圆形墙为变截面墙体，上部墙体向内侧收敛，使得上部圆形墙外模板无支撑基础，采用在下部圆形墙外模板的顶端固定支撑杆，通过支撑杆支撑固定上部圆形墙外模板，该支撑杆连接牢固，确保施工质量，解决了变截面墙体的支模问题。
摘要（英）：

The utility model relates to a cross-section-variable circular wall formwork erecting structure. The cross-section-variable circular wall formwork erecting structure comprises a circular inner-wall formwork, a circular outer-wall formwork and split bolts, wherein the circular inner-wall formwork and the circular outer-wall formwork are oppositely arranged, and the split bolts are used for fastening the circular inner-wall formwork and the circular outer-wall formwork. The circular outer-wall formwork comprises a first outer formwork body erected at the lower portion and a second outer formwork body erected at the upper portion, the second outer formwork body is close to the circular inner-wall formwork compared with the first outer formwork body, the first outer formwork body is erected on the ground, a supporting rod is arranged at the top end of the first outer formwork body, and the second outer formwork body is erected on the supporting rod. A circular wall is a cross-section-variable wall, an upper wall body is retracted towards the inner side, and therefore the upper portion of the circular outer-wall formwork is free of a supporting foundation; the supporting rod is fixed to the top end of the lower portion of the circular outer-wall formwork, the upper portion of the circular outer-wall formwork is fixedly supported with the supporting rod, the supporting rod is firm in connection, the construction quality is guaranteed, and formwork erecting of the cross-section-variable wall is achieved.
