SDW

Konstruksjonsskrue, skivehode

SDW er en skrue for innendørs bruk. Egnet til bruk ved sammenføyning av f.eks. dobbelsperr, hvor man kun har tilgang fra én side. Det store hodet fjerner behovet for underlags skive.

1. Uniformly Distributed Load

2. Structural Composite Lumber

3. The load is uniformly distributed from hangers at regilar centres up to 600mm maximum

4. To calculate the maximum allowable end reaction for each hanger - multiply the UDL by the spacing e.g. 3.51x 0.6 = 2.1kN per hanger

5. To calculate the maximum span of trimmed joists use: 2 x UDL (from above table) / Floor Load (kN/m²) e.g. 2 x 3.51 / 3.12kN

Montering

Monteringsveiledning

SDW skruer monteres bedst med langsomme omdrejninger og en T40 bit (Bit er inkluderet i hver kasse)
Forboring er ikke nødvendig. SDW skruen kan monteres gennem stålspær iht. spærleverandøren
Iskru skruen, således hovedet er let undersænket i træet, for at sikre de korrekte værdier
Indbyrdes afstande mellem skruerne kan justeres op til 75 mm

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

Shear capacities are given for thick (t_st = d) and thin (t_st = 0,5xd) steel plates under the following configurations:

Load axis at 0° from timber grain R_v.0°.k
Load axis at 90° from timber grain R_v.90°.k

These capacities are valid for C24 timber grades or higher.
For intermediate steel thicknesses, capacities shall be calculated by linear interpolation between the limiting thin and thick plate values.
The pre-drilled hypothesis for capacity and distances calculation is fulfilled.
