Create assembly with connecting parts

Define whether or not the connecting parts (shim plate, washer, nuts) are welded together.

Weld connecting parts

Define which parts are welded.

Parts tab

Use the Parts tab to define the part properties.

Parts


Option	Description
Connection plate	Thickness, width, and height of the connection plate.
Round plate	Thickness, width, and height of the round plate.
Filler	Select the profile from the profile catalog. Tekla Structures creates a simplified shim plate. In reality, the plate is curved on one side, equal to the radius of the round plate. Enter the width and height, for example `PL5050` or `5050`.
Washer	Select the profile from the profile catalog.
Nut	Select the profile from the profile catalog.
Extra nut	Select the profile from the profile catalog.
Tube	Select the profile from the profile catalog.


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.
Comment	Add a comment about the part.

Thickness dimensions


	Description
1	Thickness of the shim plate.
2	Thickness of the washer.
3	Thickness of the nut.
4	Thickness of the extra nut.

Parameters tab

Use the Parameters tab to define the rod and hole dimensions.

Hole creation

Define how the hole is created in the main part.


Option	Example
Hole by part cut
Hole by bolt
Hole by part cut and bolt

Connection method

Define how the round plates are joined to the connection plate.

Dimensions


	Description
1	Diameter of the rod end.
2	Offset from the secondary part edges.
3	Length of the connecting piece. You can define this if a tube is created. Length is measured along the center line.
4	Slot length in the main part.
5	Rod length to the center of the main part.
6	Rod length to the center of the main part.
7	Define how the callote is welded. When not welded, the calotte is connected to the main part with a bolted connection.
8	Vertical offset of the round plates. Define a value to offset the plates in the vertical direction.
9	Slotted hole height.
10	Slotted hole width.
11	Define how the rod connection is welded.
12	Slotted hole height in the main part.
13	Slotted hole width in the main part.

Bolts tab

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

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.
	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.
	Dimension for vertical bolt group position.

Basic bolt properties


Option	Description	Default
Bolt size	Bolt diameter.	Available sizes are defined in the bolt assembly catalog. `16 mm`
Bolt standard	Bolt standard to be used inside the component.	Available standards are defined in the bolt assembly catalog. `4014-8.8`
Tolerance	Gap between the bolt and the hole.	`4 mm`
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`

Cut length

Defines the depth at which Tekla Structures searches for the sections of the bolted parts. You can determine whether the bolt will go through one flange or two.

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.

Examples of slotted holes

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.

UDA tab

Use the UDA tab to define the user-defined attributes for the connection plate.

You can define the fabricator name, type, nomination, article number, product code, and product description.
