15.2 Formwork and reinforcement works
Columnar foundation
The main type of formwork for the concrete monolithic columnar foundation is portative–movable small– panel ready–made form – wood, wood–metal and metal. For large volumes of work are used demountable and one–piece block forms.
Portative–movable formwork is installed element by element. Assembly and disassembly of small– panel formwork to be done manually. Block –forms are spatial frame structure, which is installed in the design position and lifted by a crane. With a relatively small amount of the same type foundations it is recommended to select of small–panel formwork.
With the diversity of the proposed small–panel forms in Course Project is allowed to restrict with the determination of standard sizes panels without being tied to specific types of formwork and determination of the panels requirement.
Dimensions of the main panels, flat and angle should be a multiple to
300 mm enlarged module, spacer panel–module 100 mm.
Layout of panels on the formed surfaces to be shown on the plans of the individual stages and column
footing and on the foundation side
