Tube rail (113)

Tube rail (113) creates a connection between one or two RHS rails and a column. The RHS profiles are outside the flange. The connection creates bolts for the connection and the rails. A small piece of rail for an extension can also be created.

Objects created

  • Temporary profile

  • Bolts

Use for

Situation Description

Connection between one or two RHS rails and a column. The RHS profiles are outside the flange.

To ensure that the bolts can be tightened, the connection can create either a 45-degree cut in the rail or large holes in the opposite flange for the wrench to go through.

Beam to beam bearing tube steel rails to the main part, with cope or hole bolt access options.

Selection order

  1. Select the main part.

  2. Select the first secondary part.

  3. Select the second secondary part.

  4. Click the middle mouse button to create the connection.

Picture tab

Dimensions

Description

1

Vertical bolt spacing.

2

Bolt edge distance from the secondary part edge.

3

Horizontal bolt spacing.

Parts tab

Use the Parts tab to define the temporary profile properties.

Properties

Option

Description

Default

Pos_No

Prefix and start number for the part position number.

Some components have a second row of fields where you can enter the assembly position number.

The default part start number is defined in the Components settings in File menu > Settings > Options.

Material

Material grade.

The default material is defined in the Part material box in the Components settings in File menu > Settings > Options.

Name

Name that is shown in drawings and reports.

Parameters tab

Use the Parameters tab to define the secondary part cut, attachment, dimensions, temporary profile, secondary part offset, and hole creation.

Beam cut angle

Description

1

Beam cut angle

Secondary part cut

Option Description

Secondary parts are not cut.

Secondary parts are cut.

Hole diameter

Description

1

Hole diameter

Temporary profile width

Description

1

Define the width of the temporary profile.

The profile is created only if you define the width.

A temporary profile serves as the second secondary part when the component is used for only one secondary part. The temporary profile is needed for the offset between the parts to work.

Secondary part offset

Option Description

Secondary part is not offset from the column center.

Secondary part is offset from the column center. Define the offset dimension.

Hole/bolt creation

Option Description

Bolts are created.

Holes are created.

Blts/Rail tab

Use the Blts/Rail tab to define the bolt properties.

Bolt basic properties

Option

Description

Default

Bolt size

Bolt diameter.

Available sizes are defined in the bolt assembly catalog.

Bolt standard

Bolt standard to be used inside the component.

Available standards are defined in the bolt assembly catalog.

Tolerance

Gap between the bolt and the hole.

Thread in mat

Defines whether the thread may be within the bolted parts when bolts are used with a shaft.

This has no effect when full-threaded bolts are used.

Yes

Site/Workshop

Location where the bolts should be attached.

Site

Bolt assembly

The selected check boxes define which component objects (bolt, washers, and nuts) are used in the bolt assembly.

If you want to create a hole only, clear all the check boxes.

To modify the bolt assembly in an existing component, select the Effect in modify check box and click Modify.

Bolt length increase

Define how much the bolt length is increased. Use this option when, for example, painting requires the bolt length to be increased.
