Wooden purlin shoe (15)
Wooden purlin shoe (15) creates a connection between a steel beam and a wooden purlin. A purlin shoe is welded to the steel beam, in which a wooden purlin is fitted. You can use various profiles to create the purlin shoe, for example, U-shaped and L-shaped profiles. The purlin shoe has holes so the wooden purlin can be connected using hexagon head wood screws.

Picture tab
Use the Picture tab to define the offset dimensions of the shoe profile, base plate, and notch.
Offset dimensions
| Description | Default | |
|---|---|---|
|
1 |
Shoe profile offset from the purlin top. |
|
|
2 |
Shoe profile offset from the steel beam top. This dimension takes priority over the shoe profile offset. |
5 mm |
|
3 |
Bottom plate offset in the direction of the wooden purlin. If you do not enter a value and the steel beam bottom is further down than the wooden purlin bottom, the bottom plate extends automatically to the main part web. For example:
|
0 |
|
4 |
Bottom plate offset in the direction of the main part. |
0 |
|
5 |
Notch offset. When the shoe profile width is insufficient, the wooden purlin is notched. |
Parts tab
Use the Parts tab to define the shoe profile and bottom plate properties.
Parts
| Option | Description |
|---|---|
|
Bottom plate |
Thickness of the bottom plate. |
|
Profile |
Select the shoe section profile from the profile catalog. If you do not select any profile, the shoe profile shape selected in Section type is used. |
|
Section type |
Select the shoe profile section type. Section type is used when a profile is not defined in Profile. Which profile is used depends on the wooden purlin width. The shoe profile has to be chosen so that the wooden purlin fits the shoe without needing to notch the wooden purlin. Catalog profiles are used, except for the last two options: U-shaped bent plate and L-shaped bent plate. When you use either of these, you can select in Create shoe as whether the U-shaped or L-shaped profile is created as a folded plate or a polybeam. If you create a polybeam, you can create an unfolded bent plate drawing with bent lines. |

if you have selected the If you use a value that is not valid, the shoe profile will disappear. |
|
2 |
Shoe profile flange height. You can define the flange height for U-shaped bent plates and L-shaped bent plates. |
|
3 |
Shoe profile flange thickness. You can define the flange thickness for U-shaped bent plates and L-shaped bent plates. |
Shoe reference line
Define the position of the shoe profile reference line.
L position
Select the shoe profile position if the profile is L shaped. The options are left or right:
Create shoe as
If you have selected a U-shaped bent plate or an L-shaped bent plate in Section type, you can select whether the plate is created as a folded plate or a polybeam.
Note:
Select Polybeam to create an unfolded bent plate drawing with bent lines.
If you select Folded plate, you cannot create an unfolded bent plate drawing with bent lines.
Holes tab
Use the Holes tab to define the hole properties and the pattern in the shoe profile.
Basic properties
| Option | Description | Default |
|---|---|---|
|
Bolt standard |
Bolt assembly standard to be used inside the component. The available standards are defined in the bolt assembly catalog. |
The default value is 4014-8.8 . |
|
Bolt size |
Hole diameter. |
18 mm |
|
Assembly type |
Location where the bolts should be attached. |

Slotted holes
| Description | Default | |
|---|---|---|
|
1 |
Vertical dimension of the slotted hole. |
0, which results in a round hole. |
|
2 |
Horizontal dimension of the slotted hole, or allowance for oversized holes. |
0, which results in a round hole. |
Dimensions
| Description | |
|---|---|
|
1 |
Hole edge distance. Edge distance is the distance from the center of a bolt to the edge of the part. |
|
2 |
Number of holes. |
|
3 |
Hole spacing. Use a space to separate the spacing values. Enter a value for each space between holes. For example, if there are 3 holes, enter 2 values. |
Vertical offset
Define the vertical shift between the bolt groups.
If the purlin is screwed at the same height on both sides of the shoe profile, the screws may hit each other. To prevent this, one hole pattern can be vertically shifted. In this way, the screws cannot hit each other. The default value is 0. For example:
Note that the vertical offset can only be used when you do not enter a vertical edge distance for the bolt group to be shifted. If you enter a value for these edge distances, the edge distance is applied and the hole pattern is not shifted vertically.
Extra weld parameters tab
Use the Extra weld parameters tab to define how the shoe profile is connected to the main part.
Connect parts as
Note:
Set the desired connection type before adding the component in the model.
If you have to change the connection type after you have added the component in the model, you have to delete the component and recreate it with the changed connection type.
| Option | Description |
|---|---|
|
Secondary part of welding |
The shoe profile is dimensioned and labeled as a welded part in the assembly drawing. It is not possible to create a separate assembly drawing of the shoe profile. |
|
Sub-assembly |
The shoe profile is added as a sub-assembly. It is possible to create a separate assembly drawing of the shoe profile. In the assembly drawing of the main part, the position of the sub-assembly is dimensioned but the dimensions of the sub-assembly parts are not. This is because this sub-assembly is already fabricated when it is welded to the main part. This results in better readable assembly drawings. |
