connections of timber beams to concrete

WabaFix

• universal heavy-duty connection up to 94.72 kN per fastening point (with wood-wood connection).
• Beam and wall connections, ceiling joists and wall elements are easily attached with it.
• load absorption without the risk of slippage during installation – unlike hook-on connectors.
• Can be arranged in multiple layers.
• Can be screwed with the self-drilling, fully threaded screw GoFix® S+ to bear static loads in four directions.
• Can be fastened to concrete with BeziFix® anchors measuring 7.5 mm.
• Available in two sizes.
• WabaFix® can be easily dismantled.
• Developed, patented and manufactured in Austria.
• Made of aluminum and monitored during production.
• Design values at www.sihga.com

SIHGA® will do the calculations for you. Please direct all questions to bemessung@sihga.com

New:

• The screw lengths can be selected differently. This allows you to optimize the connection performance for your project.
• A verifiable and auditable calculation model from Graz University of Technology is available for download: https://www.sihga.com/en/service/online-measurements/
• 6 different types of loading can be depicted according to the calculation model, including connections with flexible bearings.
• The calculation model also allows for the verification of inclined beam connections.
• For concrete connections, the SIHGA design program Jointplan also offers the possibility to design for seismic loads. Jointplan is available free of charge at https://www.sihga.com/en/service/online-measurements/ in the “S³ STATICS Software” package.
• WabaFix will soon receive a CE marking.

HobaFix Max

Connectors for main and secondary beam constructions.

The thread-cutting locking screws distribute the load equally over the entire connector height and fix the position of the two beams in relation to each other at the time of screwing . This allows an installation tolerance in the insertion direction of +/- 8 mm.

Timber-timber or timber-concrete connections are possible with HobaFix® Max.

• In the timber beam to be connected, the self-tapping fully threaded screw GoFix S+ is inserted at an angle into the end grain at two angles.
• On the concrete side, the anchorless BeziFix anchor 7.5 x 80 is used.
• For wood-to-wood connections, the fully threaded screw GoFix HK is used in the main beam or the wooden wall.
• The fastening screws are arranged in an offset pattern to avoid screw collisions.

• Multiple node connections of, for example, four beams on one column can be realized with it.
• Thanks to the ingenious coupling of the connectors using thread-cutting screws, several connectors can also side and on top of each other.
• Thanks to the practice-oriented geometry of the connector, length tolerances of the secondary beam of up to 3 mm can be absorbed (with connectors on both sides).

• Can be used in four load cases, statically highly resilient, up to 81.73 kN characteristic per connection (for wood-wood connection).
• Can be used for horizontal, vertical, tensile and moment loads with high tested static values.
• All required screws are always included in the SIHGA delivery.
• Available in 9 lengths, the width is always the same at 57 mm.

• Excellent price-performance ratio.
• All connector sizes can be mounted with just one template.
• Developed, patented and manufactured in Austria.
