ESCRFT

Strukturell helgängad träskruv med cylinderhuvud

ESCRFT är en strukturel träskruv och finns tillgängliga i en rad olika dimensioner. Skruvarna är framtagna speciellt för korslimmat trä (KL-trä), limträkonstruktioner, balkförstärkning och generella applikationer inomhus eller i torr miljö.

Egenskaper

Material

Gulförzinkad ytbehandling för applikationer inomhus och i torra miljöer

Egenskaper

Litet cylinderhuvud, kan försänkas i trä för dolda montage
Vass spets ger lågt indrivningsmoment där ingen förborrning krävs
Grov diameter och optimal gängdesign tillför styrka och stabilitet

Applikationer

Sammanfogning av KL-träpaneler: Vägg mot vägg, golv mot golv, splines etc.
Andra generella applikationer i trä så som ramverk och bjälklag.

When to use

Timber to timber assembly
Timber reinforcement (to transversile tension or compression)
Crossed pair of screws assembly for optimal capacity

These capacities are valid for:

Timber element under the head with thickness ≤ t₁ disclosed in adjacent column
Screw axis between 45° and 90° from timber grain for ESCR(XXX), and 90° from timber grain for all other screws.

For tightening screws (partially threaded), t₁ dimension is the maximum thickness of the under-head timber member for which the thread is fully in the pointside timber member, for an optimum installation and tightening.

The shear capacities are given for several timber thicknesses t₁ of the under-head member under the following configurations:

Load axis at 0° from both timber grains R_v.0°.k
Load axis at 90° from both timber grains R_v.90°.k

These capacities are valid for C24 timber grades or higher
The pre-drilled hypothesis for capacity and distances calculation is fulfilled.
For partial threaded screws, capacities are only given for configurations where the thread is less than 5mm in under-head timber member, in order to achieve optimum installation and tightening.
Clause (2) in 8.3.1.2 from EN1995-1-1:2004+A2:2014 about embedment length is ignored in these calculations.
