Purlin Joint, 2 Plates with Mitre Cut acc. to DAST IH (1201) (3-D SE)

"Civil Engineering functions" docking window > Steel Engineering > Connections > Front side to front side > Front plate > Purlin joint, 2 plates with mitre cut acc. to DAST IH (1201)

The function connects two beams by means of two rigid, bolted front plates. These can either be fitted flush or with top, bottom or lateral projection. The bolting can be aligned symmetrical or unsymmetrical. If required, the beams are automatically be shortened, lengthened or mitred in the process.

Example 1:

Example 2

Identify the first beam at its reference end.
Identify the second beam.
The Purlin joint, 2 plates with mitre cut acc. to DAST IH dialogue window will be displayed.

Purlin joint, 2 plates with mitre cut acc. to DAST IH dialogue window

Two assemblies will be created, each of them containing the beam and the corresponding plate. The bolting will be assigned to the first identified beam.

Manage configurations

Configurations for purlin joints can be saved, which enables you to access your individual configurations at any time afterwards.

More about configurations

Configure purlin joint

The configuration takes place via the tabs of the dialogue window.

Selected parts

This tab provides information about the previously identified beams, e.g. designation, material, dimensions etc. Value inputs or modifications are not possible here.

Front plate

In this tab you specify the settings for the plate.

Front plate tab

Clearance

Here you enter the value fore the clearance, i.e. the distance of the plate from the second identified beam.

Semi-finished product

The plate can consist of sheet metal or flat steel. Click the icon to select plate type and material directly from the corresponding standard part catalogues.

Geometry

You can choose between three methods for the definition of the geometry (size) of the plate. Select the desired method from the Definition listbox.

Definition - Absolute
A plate defined by the specified width/height is fitted, which can be moved by a specified offset in x- or y-direction. The values specified for the offset determine the distance from the plate's centroid to the beam's centroid.

Furthermore, you have the following options for the positioning of the plate:

Front plate x / y
You can position the plate, through specification of the corresponding settings, in such a way that particular points on the plate or a bore lie exactly in the centroid of the beam cross-section (1st beam).

Positioning options

Beam x / y

The plate will be positioned in such a way that the centroid of the beam cross-section lies in one of the displayed points of the beam:

Positioning options

If you have specified an offset, the plate will be moved accordingly.

Definition - With projection
The plate size is determined by the identified beam and the specified projection.

Example

Definition - With projection beyond grid
The plate size is determined by the identified beam and the specified projection beyond the bore grid.

Example

Boltings

Here you can define the bolting set, e.g. type of the bolt, bore diameter etc. Click the icon and select the bolting components. Proceed in the same way as you would do with the Steel Engineering Boltings function.

Grid

The bore grid determines the position and arrangement of the bores on the end plate.

X- and Y-offset (distance to centroid of beam)
Number of bores in X- and Y-direction and their distance to each other. If you want all bores running in one direction to have the same distance to each other, you can simplify the data entry by doing the following: Enter the distance value into Change all field. All fields will automatically be assigned the entered value.

Weld seams

Weld seams tab

Activate the corresponding checkboxes to select the edges on which you want to place the weld seams. You can select a weld seam type for each edge and specify the thickness of the seam. Furthermore, you can define weld seam annotations for all edges to be welded together. Click the , symbol to open the Weld seam dialogue. It is operated largely in the same way as the dialogue of the 3-D function Insert weld seam symbol.

After entering all required data, you can fit the purlin joint. If you select Apply, the purlin joint will be fitted, but the dialogue window will remain open. If you select OK, the purlin joint will be fitted, and the dialogue window ill be closed. If you select Close, the changes will be discarded and the window will be closed without fitting the purlin joint.
