Node 1: Options for Supporting Rafters on the Wall Plate
There are several methods for supporting and securing truss rafters made of I-beam wooden beams on the wall plate.
The most common methods include:
1) cutting a notch with the necessary angle into the wall plate timber;
2) mounting the rafters on Simpson brackets (VPA bracket with an adjustable angle);
3) placing prisms made of timber (or LVL timber) to increase the support area.
For rafters longer than 6 meters, it is recommended to use plywood/OSB inserts at the supports to reduce the load on the I-beam post. Block beams are necessary for additional rigidity of the structure, ensuring the stability of the rafters in a vertical position.
Materials and Components:
- Wall plate (timber, plank)
- Wooden I-beam rafters
- Block beams
- OSB-3/plywood insert
- Screws/nails
- VPA bracket
- Notch in the wall plate
- Prism from LVL/wooden timber

Node 2: Solution for Eave Overhang. Front Board Angled.
This node is used when a wide eave overhang end is needed, for example, for architectural reasons in homes styled like “chalets” or “half-timbered” houses. For this, the ends of the I-beam rafters are reinforced with board inserts on both sides. A front board is attached to these inserts.
Node 3: Solution for Eave Overhang. Vertical Front Board.
A standard node with the completion of the eave overhang using a single front board. The ends of the I-beam rafters are reinforced with horizontally placed board or plywood inserts. Block beams are essential for additional rigidity of the structure, ensuring the stability of the rafters in a vertical position.
Materials and Components:
- Wall plate (tie beam)
- Wooden I-beam rafters
- Block beams
- “Nest” in the wall plate for rafter installation
- Structural angle bracket
- Rafter end reinforcement (board, plywood)
- Nails/screws
- Front board
