Adjusting mechanism, inner cylindrical formwork and elevator shaft formwork equipment
An adjusting mechanism is disposed on an inner cylindrical formwork. The inner cylindrical formwork comprises at least one set of inner forms, each set including a corner form and two side forms are disposed on two opposite sides of the corner forms in a face-to-face moving or opposite moving manner. The adjusting mechanism comprises drive members, drive wheels and racks. The drive members are movably disposed on the corner forms and drive the drive wheels to rotate. Two racks are disposed on two opposite surfaces of two side forms, respectively; one end of each rack is connected with the corresponding side form, and their other ends extend to each other and mesh with the drive wheels. The adjusting mechanism is disposed on the inner cylindrical formwork of elevator shaft formwork equipment; during elevator shaft casting, formwork erecting and stripping steps can be finished easily just by driving the drive members in the adjusting mechanism to drive the inner cylindrical formwork to retract inward or stretch out; production efficiency is substantially improved. The invention further provides an inner cylindrical formwork and elevator shaft formwork equipment.
