Timber construction connections
...Connections to main and secondary beams, in truss, to longitudinal connections

In addition to the component design, one of the main focuses of DC statics is the verification of timber construction connections . Through connections, components can be weakened, which must be taken into special consideration. Often, other materials, such as pin-shaped fasteners, sheets and mouldings are necessary to remove the existing forces. All these special features can be taken into account when calculating timber-construction connections.

Overview of connection situations
  • Carpentry connections
    • Tenon

    • Dowel
    • Bolts, fitted bolts
    • Threaded rods
    • Timber connectors
    • Nails
  • Gusset plates and butt straps
    • Steel sheets found inside and outside
    • Butt straps made of wood and wood-based materials
  • Main and supporting beams (with and without Lateral tension reinforcement)
    • Metal connectors
    • Dovetail connections
    • Tenon
    • Notches
    • Profile connection
  • Column shoe
    • attached and concreted column footing
  • longitudinal joints
    • Scarf joints (Gerber)

Timber construction connections can be calculated in separate positions. You have the possibility to adopt the forces of components calculated in DC-statics or to enter the cutting forces manually as a characteristic force or design force.

In many modules, however, it is also possible to verify the components including the connections in one and the same static position. For example, in the position type, collar beam roof, rafter roof, plate roof clamps and the suspensions of middle plates are calculated in a single calculation. Timber construction connections are also available in general mullions and incontinuous beam.


Carpentry connections

Pins , offsets and offsets with pins as timbering connections in DC-statics.

Tenons with and without trim dimensions are calculated. The incoming component can be found at any angle to the traversing component. From an angle of less than 70 °, the tenon is calculated with the design rules of offsets, since this then acts as such.

In addition, front, rear and double offsets can be generated. In the offset design, the necessary length of the shear block is determined.

Clamping connections

With the help of the T-connection pliers can be connected with different pin-shaped fixtures with a rectangular cross-section. It does not matter whether the incoming or the end-to-end component is designed as a pair of pliers.

Bolts, dowel pins and threaded rods are available in the pliers connection. These fasteners can optionally be supplemented with dowels of special design. Also dowels can be selected. To achieve a secure position, dowels can be combined with fitted bolts. The displacement of lanyards is possible of course, but has an effect only with nails, as per the current standardization.

Gusset plates and butt straps

With this connection, you can account for both the slotted sheets as well as the external tabs. Also sheets between clamp cross sections are measured. Rod dowels, fitted bolts and nails available as fasteners.

In addition to steel sheets, flanges made of wood and wood-based materials (Kerto Q, BFU, OSB) also can be calculated.

The components and sheets / flanges are automatically blended together. The user determines the shape and size of the sheets / straps through the parameters of the connection as well as the type of intersection of the components.

Main and support beam connections

Beam connections are connections made of horizontal components, arranged in an orthogonal pattern.

The components can be fitted with joist hangers, beam supports and connectors (extension Metal mount connection), Dovetail tenons, tenons and notches. It is also possible to support the components using profile connection in steel profiles.

The dimensioning of the dovetail tenon is made as per the current approval of the HIGH-TECH-ABBUND Association.

If required, the joist connections can be reinforced with full-thread screws against transverse tensile failure.

Column shoe

As a component of the add-on module for fitting connectors, it is also possible to calculate attached and cast-in column feet. Current models from different manufacturers are stored in DC statics and can be directly compared with each other.

Longitudinal joints

As a longitudinal connection, the scarf joints (Gerber) is available. The connection can be detected as "hanging" as well as overlying. In the first case, the fasteners are exposed to tensile stress. In the second situation, the contact pressure is detected. Dowel pins, bolts and threaded rods can be used as fasteners.
