AI Technical Summary
Technical Problem
During the construction of traditional variable-section concrete cylindrical inner molds, the formwork cannot be reused, resulting in waste of materials and high costs, and the construction period is extended.
Method used
A variable diameter arc inner mold is designed. By adjusting the combination of the template unit and the base template unit, the locking mechanism of the sliding truss and the locking device is used to adjust the bending and length to adapt to deformation of different cross-sections.
Benefits of technology
The reuse of the formwork is realized, reducing material consumption and cost, while shortening the construction period and improving construction efficiency.

Abstract
The invention discloses a variable-diameter arc inner mold. The variable-diameter arc inner mold comprises an adjusting formwork unit and a foundation formwork unit, the adjusting formwork unit is provided with an adjusting formwork mechanism used for retaining concrete and a sliding truss used for being connected with an inserting-connecting formwork, and the foundation formwork unit is provided with a foundation formwork used for retaining concrete and a foundation framework used for increasing the strength of the foundation formwork. The foundation formworks are installed on the foundation frameworks, the sliding trusses are arranged on the foundation frameworks of the adjacent foundation formwork units in a sliding mode, the positions, relative to the foundation frameworks, of the sliding trusses are locked through the locking devices, and the two ends of the formwork adjusting mechanisms are connected with the adjacent foundation formworks or overlapped on the adjacent foundation formworks. And at least one basic template adjacent to the inserting template is connected with a bending degree adjusting mechanism for adjusting the bending degree. The variable-diameter arc inner mold adapts to a variable-cross-section building in a contraction and division mode, meanwhile, the foundation template unit and the adjusting template unit are repeatedly utilized, a large number of materials are saved, and the cost is low.
