Column - 2 beams (14)

Column - 2 beams (14) connects two beams to a column. The beam ends rest on the column. The secondary beams can be horizontal or sloped.

Objects created

  • End plates

  • Cap plates

  • Bolts

  • Welds

Use for

Situation

Description

Connection between a column and two beams.

Connection between a column and a beam.

You can use the component with only one secondary beam but then the settings are more difficult to define, and there are fewer situations where the component can be used.

If you use the component with only one secondary beam, enter a negative value for the gap between end plates.

Selection order

  1. Select the main part (column).
  2. Select the first secondary part (beam).

  3. Select the second secondary part (beam).

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

Plate thickness, width and height.

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.

Class

Part class number.

Plate 3 + 4

Define the type of the connection between the column and beams.

Option

Description

Example

2 plates

Two plates are created. The column is chamfered twice.

Folded plate

A folded plate is created. The plate can be unfolded on a workshop drawing. The column is chamfered twice.

1 plate

One plate is created. The plate is always oriented horizontally. The column is fitted perpendicularly.

Plate perp to column

One plate is created. The column is fitted perpendicularly, even if the column is positioned in a skewed direction.

Plate distances

Description

Default

1

Plate distance from the beam edge.

5 mm

2

Gap between the end plates.

If you use the component with only one secondary beam, enter a negative value.

3

Plate distance from the column edges.

4

Plate distance from the column center.

End plates

Select how the end plates are positioned.

Gap size

Define the limit value for the gap between the end plate and the beam, or for the gap between the cap plate and the column. Use this when the beam or the column is slightly curved or sloped to decide if the end angle is so small that the end can be straight.

If the actual gap is smaller than this value, the end of the beam is left straight.

If the actual gap is larger than this value, the end is fitted to the end plate or to the cap plate.

The default value is 5 mm.

Bolts 1 - 2 tab

Use the Bolts 1 - 2 tab to control the bolts that connect the end plates.

Bolt group dimensions

Description

1

Select how to measure the dimensions for horizontal bolt group position.

  • Left: From the left edge of the secondary part to the leftmost bolt.

  • Middle: From the center line of the secondary part to the center line of the bolts.

  • Right: From the right edge of the secondary part to the rightmost bolt.

2

Dimension for horizontal bolt group position.

3

Bolt edge distance.

Edge distance is the distance from the center of a bolt to the edge of the part.

4

Number of bolts.

5

Bolt spacing.

Use a space to separate bolt spacing values. Enter a value for each space between bolts. For example, if there are 3 bolts, enter 2 values.

6

Dimension for vertical bolt group position.

7

Select how to measure the dimensions for vertical bolt group position.

  • Top: From the upper edge of the secondary part to the uppermost bolt.

  • Middle: From the center line of the bolts to the center line of the secondary part.

  • Below: From the lower edge of the secondary part to the lowest bolt.

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

Slotted holes

You can define slotted, oversized, or tapped holes.

Option

Description

Default

1

Vertical dimension of slotted hole.

0, which results in a round hole.

2

Horizontal dimension of slotted hole, or allowance for oversized holes.

0, which results in a round hole.

Hole type

Slotted creates slotted holes.

Oversized creates oversized or tapped holes.

No hole does not create holes.

Rotate Slots

When the hole type is Slotted, this option rotates the slotted holes.

Slots in

Part(s) in which slotted holes are created. The options depend on the component in question.

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.

Bolts 3/Bolts 4 tabs

Use the Bolts 3 and Bolts 4 tabs to control the bolts that connect the first secondary beam or the second secondary beam to the column.

Bolt group dimensions

Description
