Purpose and description

Formwork placing tools - Slabs is a set of components to help detailed modeling of typical slab formwork. These components are placing tools and to use these tools you need to have all relevant formwork products such as panels, girders, shuttering props etc. loaded into your Applications & components catalog. You can get formwork components provided by formwork suppliers from Tekla Warehouse. In addition, these tools require additional configuration files containing necessary information about formwork product components. In an ideal case, these configuration files come along with the formwork product catalogs provided by formwork suppliers, but you can also create configurations yourself.

Using Formwork placing tools - Slabs

Formwork placing tools - Slabs contains tools to place and modify the following formwork elements:
  • Formwork panels typically appearing as two-dimensional arrays covering a certain area
  • Cross and main girders supporting the panels
  • Shuttering props supporting the girders or panels directly depending on the formwork system
  • Stop ends on top of panels
  • Safety railings in the outer edges of the panel area

Panels (Formwork slab panels)

 
Formwork slab panels is the main component used to create the formwork panels for the slabs. You can use this same dialog box to insert the other formwork placing slab components and to define their properties.

To create a new area of panels:
  1. Open the Formwork slab panels main dialog box by clicking the component in the Applications & components catalog.
  2. Select the Formwork supplier and Product family from the dropdown lists. Note that the options may vary depending on which catalogs and tool configurations you have downloaded.
  3. Select the panel from the Formwork panel list.
  4. Click the Insert new button.
  5. Move the mouse pointer on top of the slab to identify the bottom surface.
    • Click the left mouse button and pick three or more points to identify the area on the surface. A preview of the panels is shown while you are picking. Finish the picking with the middle mouse button.
    • As an alternative, hold down the Alt key when selecting the surface. In this case, the whole surface will be covered with panels.

Cross and main girders (Formwork girder line)

Depending on the formwork system there may be cross and main girders in two directions, or only main girders or no girders at all. 

You can either create all girders by once by selecting the panel area and clicking the Add to selected button, or you can create a single line of girders by clicking Insert new.

To create all girders: 
  1. Select the girder from the list.
  2. Select the girder layout.
  3. Give girder Overlap value or leave it empty and let the tool to set it automatically
  4. If girder Lenght(s) are not fixed and row is not greyed out, they can be defined on the dialog. Use space as a separator if you need to have girders with different lenghts. 
  5. Select the panels area in the model view with .
  6. Click the Add to selected button.
  7. Enter the start distance and spacing of the girder lines.
  8. You can also select the option to create girders at panel area edges or not and the girder layout at the panel seam.
  9. Click the Create button when the girders are created.

Shuttering (Formwork prop)

You can either create multiple shuttering props by selecting the panel area, or one or more girder lines, and clicking the Apply to selected button, or you can create a single props line of girders.

To create multiple shuttering props:
  1. Select the prop, prop head and prop base from the Prop name, Head name and Base name lists.
  2. Enter the total height for the prop.
  3. Select the panels area, or select one or more girder lines in the model view.
  4. Click the Add to selected button.
    The shuttering props are created.

Railings (Formwork railing)

You can insert the railings by clicking the Insert new button on the Railings tab.

To insert the railings:
  1. Select the railing type from the Railing name list.
  2. Click the Insert new button.
    • Depending on the railing type you may need to select the top face of the slab, side face of the wall, or the slab formwork panels. If the railing type is assembled on the slab panels and you have the slab panels selected, this first selecting is not needed.
    • Pick two or more points on the panels, slab top or wall face. Stop the picking with middle mouse button.

Modifying the placing components

All placing components have some direct modification tools that you can use to modify the component.

Panels (Formwork slab panels)

When selecting the panel area, you have the following options to modify the components:

Slabs - Mini Boundary.png
When this option is selected, you can modify the boundary of the panel area by using the typical polygon modification features to move edges or points by dragging or to insert new points by dragging the insertion points at the middle of the edges.

In addition, you can move the starting point (corner of the panel) and direction of the panel by dragging the special handles.

Slabs - Mini Opening.png
Click this option to add new rectangular interior openings into the panel area. Note that after adding the rectangular opening, you can edit the opening to any shape.

Typically, the interior openings are larger areas where the panels are not needed. To replace the regular panel with some special infill parts, use the single panel removal tool.

Click this option to activate the modification of main girders (if any).

You can also activate the modification of an individual girder line by selecting it.
 
Image
Slabs - Mini Props.png
Click this option to activate the modification of shuttering props (if any).

This option activates the modification of all shuttering props in the panel area. With the modification tools you can:
  • Move the individual props by dragging the point handle. Hold down the Ctrl key to create a copy of the prop.
  • Move a whole line of props by dragging the line handle. Hold down the Ctrl key to create a copy of all the props on the line.
  • In addition, you can change the shuttering prop head or base for shuttering props on all selected points and/or lines.
Note that props created for the girder lines can only be moved/copied along the girder line.

Customizing Formwork placing tools - Slabs

All formwork placing tool components are just inserting various formwork product custom parts in the model. These custom parts must exist in the Applications & components catalog when using the formwork tool components. In addition to the custom parts you need to have the formwork tools for slab configuration files available. Check whether the formwork supplier has made the configuration and whether the configuration is available with the components.

For instructions on how to make the necessary configurations for your own formwork components, check the instructions here Back to top
