Cast-in-place box girder formwork and box girder assembly process
The invention relates to the technical field of bridge construction, in particular to a cast-in-place box girder formwork and a box girder assembly technology.The cast-in-place box girder formwork comprises an outer formwork body, an inner formwork body, a tensioning assembly and a vertex angle assembly; the inner formwork is sleeved with the outer formwork, a forming cavity used for forming the box girder is formed between the inner formwork and the outer formwork, the inner formwork is formed by connecting a plurality of first supporting pieces, a second supporting piece is connected between every two adjacent supporting pieces, the first supporting pieces are used for abutting against the inner side wall of the box girder, and the second supporting pieces are used for abutting against the inner side chamfer of the box girder. The tensioning assembly is used for driving the first supporting piece and the second supporting piece to move in the direction close to or away from the outer formwork, and the vertex angle assembly is connected with the second supporting piece and used for abutting against the inner side chamfer of the box girder when the second supporting piece is away from the box girder. During mold removal, the tensioning assembly drives the first supporting piece and the second supporting piece to be away from the box girder, so that the deformation amount of the box girder during mold removal is reduced, and the finished product quality of the box girder is improved.
本申请涉及桥梁施工的技术领域，尤其是涉及一种现浇箱梁模板及箱梁装配工艺，一种现浇箱梁模板，包括外模板、内模板、张紧组件和顶角组件；外模板套设于内模板，内模板与外模板之间设置有用于成型箱梁的成型腔室，内模板由多个第一支撑片相互连接组成，相邻两个所述支撑片之间连接有第二支撑片，第一支撑片用于与箱梁内侧壁抵接，第二支撑片用于与箱梁内侧倒角抵接，张紧组件用于带动第一支撑片和第二支撑片沿靠近或远离外模板的方向移动，顶角组件与第二支撑片连接且用于第二支撑片远离箱梁时与箱梁内侧倒角抵接。本申请拆模时，通过张紧组件带动第一支撑片和第二支撑片远离箱梁，从而降低箱梁在脱模时的变形量，提高箱梁的成品质量。
