Formwork plan
A formwork plan is a supplementary implementation plan for the representation of the components to be encased in structures that are to be made of concrete . In the formwork plan, the concrete components of the structure required for the supporting structure are shown with the essential details. The formwork , i.e. the negative mold into which the fresh concrete is poured on a construction site, is manufactured and aligned according to these plans . The formwork itself is not shown in a formwork plan. If necessary, e.g. B. for custom-made products, additional detailed plans (formwork plans) are created. In Germany, formwork plans are usually created by a structural engineer on the basis of the project designer's completed work planning. Formwork plans are only valid in connection with the construction planning of the object planner. If the concrete components of the structure to be shuttered are to be produced without the construction plans of the property planner, the creation of shell plans is required as a special service.
Presentation, content and creation
Shell plans show the geometry of the component with dimensions in the form of soffits of ceilings. If necessary, additional sections, views or plan views through the concrete or reinforced concrete components to be produced are displayed. Special features such as recesses or built-in parts are only shown insofar as they are relevant for the structure of the building. As a rule, formwork plans are limited to two-dimensional representations. In the case of complicated geometries, isometrics are sometimes used .
Visible component edges and cut edges are drawn in different line widths, with cut component edges being drawn thicker; Any (invisible) edges behind it are drawn with dashed lines. Recesses are also marked with symbols.
DIN 1356-1 “Construction drawings - types, contents and basic rules of presentation” applies to formwork plans. As for all technical drawings, the form and folding of the drawings are also regulated (according to DIN 476, DIN 823 and DIN 824).
Scarf plans used to be drawn by architectural draftsmen with pencil or ink on transparent paper (for copying by taking breaks ). Today, the majority of formwork plans are created on the computer with the help of CAD programs. In addition to the formwork plan, the reinforcement plan is also required for construction . Since reinforcement and formwork must be coordinated ( concrete cover , etc.), formwork and reinforcement plans are usually created together.
Formwork planning
When using system formwork, it is necessary to plan the formwork in order to use the formwork economically. In the formwork planning, all formwork elements, formwork anchors and other parts are shown that are required to set up the formwork. The results of the formwork planning are parts lists and formwork plans in which the formwork is also shown. The formwork planning is now supported by IT programs. The corresponding software is offered by formwork manufacturers. The precondition for formwork planning is that the component is divided into concreting sections . The aim of formwork planning is to be able to work as often and continuously as possible with the smallest possible number of formwork elements.
Setup planning
For components that are concreted at high altitude, are far stretched (z. B. in bridge) or are particularly difficult (eg. As in industrial buildings), also in addition to the shell drawing Armor plan (or short setup plan ) is prepared. In the scaffolding plans, all elements of the required formwork scaffolding are shown in a manner comparable to the formwork .
