The invention discloses a steel form carrier variable camber gear for the concrete lining for a cave depot. The steel form carrier variable camber gear comprises triangular supports, fixed triangular blocks, an adjustable triangular block, a triangular block connecting pin I, a triangular block connecting pin II, a split pin, a triangular block connecting screw, a vault template assembly, and a side form assemblies, wherein the triangular supports are arranged on the two sides of the variable camber gear and are fixed at the upper part and on the inner side surface of the side form assemblies, the adjustable triangular block is arranged in the middle part of the variable camber gear, a plurality of fixed triangular blocks are arranged on the two sides of the adjustable triangular block, the split pin is installed at the end part of the triangular block connecting pin I and the triangular block connecting pin II, the vault template assembly is supported and installed on the outer side of the variable camber gear through the triangular blocks, and the side form assemblies are located on the most left side and the most right side. The steel form carrier variable camber gear has the benefits that the scope of application is wide, the regulation of the camber of a vault having different arc shapes and span ranges is adapted, the camber variation accuracy is high, the labor intensity is low, the camber variation efficiency is high, and the safety performance is excellent.
Description
technical field [0001] The invention belongs to the technical field of concrete lining construction equipment for underground caverns, and in particular relates to a steel form trolley arc-changing device for concrete lining of variable-section caverns that can adapt to changes in radian, span and height within a certain range. Background technique [0002] Due to the many changes in the section of the underground cavern project, the existence of special-shaped structural sections and lateral rooms, etc., the construction is more complicated than that of the general tunnel project. During the concrete lining of the cavern, it is necessary to frequently replace steel formwork trolleys of different specifications to adapt to different arches. At the same time, because the cavern project is affected by the actual geographical environment and construction space, its working conditions are poor, the degree of mechanization is low, and the labor intensity is high. It is necessary t...
