Bracing cross (19)

Bracing cross (19) bolts one or more twin-profile braces to an existing gusset plate.

Tip: To create a gusset plate, use the Standard gusset (1065) component, or create a countour plate.

Objects created

  • Bolts

  • Cuts

  • Welds

Use for

Situation Description

Brace profile: L

Braces are bolted directly to the gusset plate.

Brace profile: W

Braces are notched around the gusset plate and bolted to the gusset plate.

Before you start

Create a gusset plate, and 1 to 10 braces.

Selection order

  1. Select the main part (gusset plate).

  2. Select the secondary part (first brace).

  3. Select the second secondary part (second brace).

  4. Select the subsequent secondary parts (subsequent braces).

  5. Click the middle mouse button to create the component.

Note:

Tekla Structures uses values in the joints.def file to create this component.

Picture tab

Use the Picture tab define the flange cut dimension.

Description

1

Define the length of the flange cut.

Parameters tab

Use the Parameters tab to cut the brace flange.

Option Description

Fit secondary

Select whether the secondary part is fitted.

Selecting Yes fits the secondary part according to the bolt distances.

Cut other side flanges

Select whether to create a triangular cut on the opposite side of the flange.

  1. Vertical cut dimension.

  2. Cut angle.

Bolts tab

Use the Bolts tab to define the bolt group dimensions and bolt properties.

Bolt group dimensions

Description

1

Dimension for horizontal bolt group position.

2

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.

3

Bolt edge distance.

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.

Staggering of bolts

Option

Description

Default

Not staggered

AutoDefaults can change this option.

Not staggered

Staggered type 1

Staggered type 2

Staggered type 3

Staggered type 4
