Uncouple the beams professionally and secure

One of the oldest craftsmanship is the joining of wooden beams by mortising. Long before the invention of metalworking and adhesives, people created statically stable and durable constructions. The basic forms and methods have hardly changed until today and are divided into five types of tapings.

Cones and slots

The main burden when connecting wooden beams carry the taps. They are reinforced in modern roof construction by additional screw elements. When connecting with pins and the corresponding sawing of the beams, of carpenters, carpenters and civil engineers referred to as notching, five types are classified.

1. longitudinal connections (also for extending beams
2. Cross connections
3. Corner joints
4. Slanted connections
5. combings

In principle, each tapping is a more or less complex nesting of angular or round pins in the matching slots. Overlaps and mutually blocking jams result in stable beam joints with enormous load-bearing capacity.

longitudinal joints

Typical longitudinal connections are the pintle, the blade thrust and the hook blade. The appropriate tap is selected based on the force load. Hook blades best withstand tensile forces and pin and blade thrust provide lateral thrust resistance.

cross connections

The classic and best-known cross connection is the simple insertion pin. It can be used for horizontal and vertical bar profiles. A stability-enhancing shape is the oblique spine, which is asymmetrically shaped and has a sloping flank side.

corner joints

The most widespread in the tapping of beams meeting at corners is the right-angled arrangement of equally sized and straight so-called leaves. The vertical notching of the leaves creates the more stable French leaf. The Schereckblatt is a tongue that is inserted into a head slot of the opposite bar. The miter kick consists of sheet notches meeting at a 45-degree angle.

Angular connections

For oblique connections asymmetric notches are selected. The depth of the notch in the longitudinal beam shall be between one sixth and one quarter of the beam thickness. This offset depth is created with a face offset, a double offset, or a heel offset. The angle of inclination is generated by the corresponding Notklinkungsform.

Tips & Tricks

To create skids that connect beams at different heights, you need professional tools and craftsmanship. The millimeter-accurate connectors stabilize the overall construction.
