Mechanical fastening

FBN bolt anchors

Bolt anchor for push-through and pre-assembly.

• While the hexagonal nut is being tightened, the pin is pulled out and presses on the expansion clip, causing it to press against the walls of the drilled hole.
• The A4 stainless steel version should be used outdoors and in humid rooms.
• In the version with a large washer according to DIN 440 it should be used for fastening wooden elements.

  LOAD CAPACITY – example for FBN II 12/30 The highest tension load 12.6 kN at standard anchorage depth hef, stand = 65 mm. Fastening of the supporting structure of the façade requires calculations taking into account individual boundary conditions. γF = 1.4. In the case of simultaneous tension and shear loads, boundary conditions and with a group of anchors, Calculation Method A (ETAG Annex C) should be used.

The FBN II 10 anchor with an effective anchorage depth of 50 mm is obtained in the table

• permissible tension load for a single anchor without the influence of boundary conditions, i.e. edge distance c ≧ 1.5 x hef and axial spacing s ≧ 3 x hef in non-cracked concrete C20/252 Nzul = 8.5 kN,
• permissible shear load for a single anchor without the influence of boundary conditions, i.e. edge distance c ≧ 10 x hef and axial spacing s ≧ 3 x hef in non-cracked concrete C20/252 Vzul = 8.5 kN,
• permissible bending moment – Mzul = 25.6 Nm

Universal Frame Plug FUR 10 SS

• Universal frame mount.
• Anchoring in solid materials is achieved by friction forces.
• Anchoring in materials with voids is achieved by deforming the ribs and adapting their shape to the surface of the hole.
• The fastening with the fischer safety screw made of A4 stainless steel is the ideal solution for anchoring outdoors and in wet substrates.

 Advantages

• Universal mounting for all types of surfaces.
• Simple and quick assembly and disassembly.
• Patented asymmetrical teeth guarantee the highest load parameters in solid materials and in substrates with empty spaces.
• The fastener is protected against premature expansion when driving it into the hole.
• Additionally protected against corrosion.
• Wide range of products for wood and metal construction
