(2) Assembling and moving unit sections
a. A plurality of single-side support assembling units arranged side by side are arranged in the construction section, and the assembling units can be divided into basic units and additional units. Calculation verifies that when the distance between the single-side support assembly units is 800mm, 360-degree rotating travelling wheels are installed below the support bodies of the unit sections. In order to avoid overlarge forward inclination of the single-side support during movement or fixation, each support is provided with a certain proportion of balancing weights, and the setting of the positions of the balancing weights ensures the overall movement stability of the device in principle and ensures that the support body and the template cannot laterally move or deviate;
b. after the initial assembly of the unit sections is completed, the unit sections can be moved to a set position, all the unit sections are sequentially moved to a wall body, the mold assembly is prepared, all the unit section channel steel is connected by core belts and bolts, all the adjacent unit section frame bodies are connected by steel pipes, and the template support system in the whole construction section is integrated;
c. after the assembly of the single-side formwork support body is completed and before concrete is poured, the adjustable lead screw vertically arranged at the end part of the base is adjusted, and the walking wheels are enabled to be suspended without stress. And after the die is closed, concrete can be poured, and the pouring speed of the concrete is controlled according to the standard when the concrete is poured, so that layered pouring is realized. Workers can operate on the operating platform above the formwork frame body during concrete vibration, so that construction is facilitated;
d. after the concrete pouring of the construction section is completed and maintained, the adjustable lead screw at the base is adjusted, the connection with the embedded part anchoring system is removed, the connection between the channel steel of the unit sections and the steel pipe is removed, and the adjacent two unit sections are mutually independent. After the unit sections are independent, the direction of the walking wheels is adjusted to enable the walking wheels to be perpendicular to the wall surface, the whole frame body is moved backwards by 20-30 cm manually to stop, and then the formwork dismantling work can be completed. And adjusting the direction of the travelling wheels again to enable the travelling wheels to be parallel to the wall body, sequentially pushing the frame body to horizontally travel to the set position, and starting the template assembling work of the next construction section.
