Lifting bolts configuration entry

'General' tab

Display for double walls:

You can specify whether eyes or bolts are used for double walls. Eyelets are always used for concrete walls.

Minimum distance to edge:

[m] Default value for the minimum distance between the outer lifting bolt and the nearest element edge.

Move lifting bolts:
Move to next:

Yes: after having determined the position of the lifting bolts, the program moves them to the nearest lattice girder or grid point (depending on the setting). The lattice girder setting is used to improve anchorage.

Grid, edge offset/offset to axis:

[m] Default values for the offsets of the imaginary wall grid. The edge offset specified is applied to the left and bottom of the visible wall side. The edge offsets on the right and at the top are calculated from the remaining length (depending on the wall length or height) and the multiple of the value specified for offset to axis.

'Arrangement1' tab

4 lifting bolts at top:

Yes: when the element length and/or element weight exceed the specified values, the program places four lifting bolts at the top level.
Enter a high value (for example, 999) if you want the program to ignore this parameter.

When you have selected the third method for position calculation, the pairs of lifting bolts are created at the set offset.

Calculate position / factor F:

Select one of the three options provided for defining the position of the lifting bolts relative to the centroidal axis. LMin is calculated from the minimum offset between the centroidal axis and the element edge on the left or right.

With the second and third method, enter a factor for the calculation of the edge offset.

1 lifting bolt at top:

Yes: when the element length and element weight fall below the specified values, the program places only one lifting bolt at the top level.
Enter a high value (for example, 999) if you want the program to ignore this parameter.

'Arrangement2' tab

Lateral lifting bolts:

Yes: if a wall height exceeds the pallet width, it has to be rotated by 90°. This is mainly used to provide additional (lateral) lifting bolts for lifting a panel off the pallet. In addition, you can specify whether lateral lifting bolts are always installed, regardless of the wall height, or whether they are only installed when a specific wall height is exceeded.

Specify whether lifting bolts are to be applied to the right or left side of the precast element (for transport purposes) and decide whether they are to be installed always or only when a specific wall height is exceeded or when rotated production direction is selected. Lateral lifting bolts are positioned in the same way as lifting bolts at the top.

Pair of anchors at top:

Yes: if lateral lifting bolts are used, a lifting bolt pair (instead of a single lifting bolt) is applied to the side at the top opposite the lateral lifting bolts at the specified offset.

This can be useful when the element is to be turned by the crane. By using a lifting bolt pair, you can avoid overloading the single lifting bolt.

Note: This additional pair of lifting bolts is not created if there are two pairs of lifting bolts at the top level (due to the settings for 4 lifting bolts at top).

'Arrangement3' tab

Anchorage fixtures at bottom:
File / element:

Yes: the fixture defined by the file name and element name is used as the default setting. Anchorage fixtures are installed below the lifting bolts at the top.

Important: the file and element names must be the same as those specified in Allplan's fixture catalog (watch out for blanks, upper/lower case letters)!

Installation side:

Specifies the leaf (side) into which the fixtures are built.

Invisible side: the fixtures are built into the "invisible" leaf (side) as seen from the mark number.

Visible side: the fixtures are built into the "visible" leaf (side) as seen from the mark number.

Both sides: the fixtures are built into both sides.

Installation height:

At fixed height: the value specified for the fixture height is mandatory. A negative value is measured from the top; otherwise from the bottom.

As a percentage of wall height: the fixture height is calculated as a percentage of the wall height.

'Type ...' tab

Depending on the wall weight, wall area and wall height, you can place up to six different types of lifting bolts. The following settings are available for each type:

Lifting bolt:

as a bar: A reinforcing bar is used for the lifting bolt.
The length and diameter set are used.

as a fixture: A fixture is used for the lifting bolt.
The fixture defined by the file name and element name is used as the default setting. By entering a value for the Overlap, you can specify whether the fixture is to be flush (overlap = 0), countersunk (negative value) or protruding (positive value). The value set may apply to the shorter leaf.

Important: the file and element names must be the same as those specified in Allplan's fixture catalog (watch out for blanks, upper/lower case letters)!

Use lifting bolt up to:

While checking that the Wall weight, Wall area and Wall height parameters are not exceeded, the program tries to place the lifting bolt with the smallest type number (Type 1, Type 2, ...).

Enter a high value (for example, 999) if you want the program to ignore this parameter.

Enter high values for all parameters (999 to, 999 m2, 999 m) of lifting bolt Type 1 if you want the program to use only this lifting bolt type.
