Designing precast elements, regardless of module, is consistent, with only program functions slightly differing between modules. Work on precast filigree slabs, which can be prepared according to an individual design, is presented below.

ELABORATION OF COMPONENTS OF PRECAST STRUCTURE IN PLANBAR

Preparation and adaptation of the environment for the project

Catalogs

Parameters for precast elements can be defined separately in the “Catalogs” tab. After entering these parameters, users can save them and create libraries of slabs with different characteristics for a specific factory, or assign appropriate parameters for multiple factories.

For example, the width of standard “non-split” slabs (eg 250 cm or 240 cm) used by the manufacturer and the width of so-called half-size plates (122cm or another) can be defined. Users also have the possibility to configure various typical reinforcement spacing, as well as different shapes and lengths of rods protruding from slabs.

In addition, users can enter parameters such as the type of crane used on the construction site – depending on its lifting capacity and program settings, PLANBAR will assist users with dividing slabs, taking their weight into account.

Reinforcement type for elements can be redefined and adapted to each production factory. Already at the initial stage, using the results from static calculations, users can create slab reinforcement by declaring the necessary reinforcement surface required for the slab. PLANBAR automatically proposes the most suitable reinforcement type.

After basic reinforcement is defined, users can also choose additional reinforcement, i.e. reinforcement at free edges, openings, in the places most loaded. With filigree slabs, similar settings can be assigned to trusses and their spacing or only to determine boundary conditions, i.e. the maximum spacing of trusses and their distance from the panel edges – the program will adjust the spacing in accordance to the width. As with the bars, users can define additional trusses (openings, free edges, etc.)

Placement and modification

Placement

Elements can be placed into the model in various ways, depending on specific tasks and guidelines, thanks to which users can customize their work environment according to their individual needs in order to speed up work.

Ways to create elements:

  • Using a 2D drawing in a different format as a basis, *.dwg, *.dxf, *.pdf, other formats (one click anywhere in the middle of the contour)
  • By entering a new contour with 2D lines in the program (and then one click anywhere in the middle of the contour)
  • By converting already existing slabs into filigree slabs, from a model created in another program, working in accordance with BIM (Allplan, ArchiCAD, Revit, Tekla, etc.)
  • Creating the slab directly in the PLANBAR environment (each slab point must be entered manually).

Slabs can be inserted horizontally as well as inclined. In each of these methods the division of the slabs into filigree slabs is done automatically, taking into account previous settings.

One of the possible ways of creating precast slabs in the PLANBAR is presented below

The film below shows how a user can add openings to precast slabs in PLANBAR. These elements can be created in Planbar or imported from other programs working in accordance with BIM technology.

Modification

Element division and their dimensions can be modified at any moment in the design process of precast elements. This also applies to the edges of slabs (users can change the upper and lower phases on the edges), the edges at the openings (eg add consoles next to the stairs), and automatic insertion of locks at edges. After adding openings to the slabs, the reinforcement and fixtures (e.g. hooks, etc.) will be adjusted.

Slab placement may take place in relation to an indicated point or automatically according to an established rule. Division dimensions can vary.

Documentation and data for production

Shop Drawing catalogs / sheet templates

Elements for documentation, such as views, sections, plans, quantitiy take-offs, etc., can be placed manually each time or a template can be defined. Manually placed elements and their locations will be determined separately, while using templates, elements of documentation will be automatically included.

 

The video below shows one of the ways to split an architectural slab into filigree panels. It should be emphasized that this is just one of many ways to create documentation in PLANBAR. For example, users can also convert imported models and split them into precast elements or use *.dwg drawing as a basis, just one click in the middle of the contour is needed.

Data for production

There are various ways of transferring data to production factories, depending on the desired results. There are both graphic documentation and reports. In addition, when manufacturing machines and production lines support appropriate formats (UNITECHNIK), this data can be transferred directly for production.

Production data can be sent only by using an appropriate PLANBAR module (i.e. in this case filigree slab system module). The precast production process can be optimized with the program TIM.
