Maximum load transmission KonstruX fully threaded screws maximise a joint‘s load-bearing capacitywith a high thread-extraction resistance in both components. If partiallyt hreaded screws are used, the joint‘s load-bearing capacity is limited bythe considerably lower head pull-through resistance in the attached part.
APPLICATION
Applications in timber engineering and carpentry, timber-frame construction, hall construction, construction of timber elements,renovation of ceilings, etc.
Doubling up of joists, for example, increases the load-bearing capacity offloor joists and reduces bending. Here, KonstruX fully threaded screwsjoin the components together in a displacement-resistant manner.
Hidden connections, high fire-resistance, no thermal bridges
ADVANTAGES
Time saving - and cost-saving alternative to traditional connections or timberjoints such as joist hangers, joist supports, etc.
Timber has a low transverse compressive and shear strength.KonstruX fully threaded screws are inserted into the timber forreinforcement. The KonstruX “takes on” a large proportion of the forces.
BENEFITS
No pilot-drilling required in accordance with approval/ETA From screw lengths ≥ 245 mm, however, pilot-drilling to 1/3 of the screw length is advisable to guide the screw in the right direction (no screw wandering).
The required edge and centre distances can be minimised for screws that are only exposed to tension.
