Cable-stayed bridge creeping formwork mounting and climbing method
The invention provides a cable-stayed bridge creeping formwork mounting and climbing method, the creeping formwork mounting and climbing method is used for creeping formwork construction of a bridge main tower with an inclined structure, and the creeping formwork mounting and climbing method comprises the following steps: step 1, directly assembling a first section of concrete formwork on a base of the main tower; 2, a triangular hanging frame is manufactured, the triangular hanging frame is used as a second section of concrete operation platform, a formwork is assembled on the second section of concrete operation platform, a second section of concrete is poured, and a climbing cone embedded part is pre-embedded in the second section of concrete; 3, a climbing device is installed on a climbing cone embedded part pre-embedded in the second section of concrete, and the climbing device is used for ascending displacement movement of a guide rail or a bearing tripod; 4, the formwork in the previous step is moved backwards, the climbing equipment climbs upwards along the guide rail, and after the climbing equipment climbs in place, the formwork is closed, and the next section of concrete is poured; the step is repeated until formwork climbing cannot be continued; and 5, according to the main tower structure, main tower creeping formwork construction is completed.
本发明提供斜拉桥爬模安装及爬升方法，爬模安装及爬升方法用于具有倾斜结构的桥梁主塔的爬模施工，所述爬模安装及爬升方法包括以下步骤：步骤1，在主塔的基座上直接拼装首节混凝土模板；步骤2，制作三角挂架，利用三角挂架作为第二节混凝土操作平台，在第二节混凝土操作平台上拼装模板，并浇筑第二节混凝土，在第二节混凝土中预埋爬锥埋件；步骤3，在第二节混凝土中预埋的爬锥埋件上安装爬升装置，爬升设备用于导轨或承载三脚架的上升位移运动；步骤4，将上一步骤中模板后移，爬升设备沿导轨向上爬升，爬升设备爬升到位后，合模并浇筑下一节混凝土；重复本步骤，直至无法继续爬模；步骤5，根据主塔结构，完成主塔爬模施工。
