Specifications of intended use

Anchorages subject to:

• Static and quasi-static loading.

Base material

• Façade panels made of natural stone in accordance with EN 1469:2015.
• Natural stone free of open seams and mechanically active cracks and alterations.
• Natural stone classified in accordance with Table B1.
• Characteristic values of the panels correspond to Table B2.

Table B1: Stone groups

1. Fertaine parallel mo the rates randomly and pereiratari he its or the petals fan stray shal nor bo more than 50 %.

Use conditions (Environmental conditions):

• According to EN 1993-1-4:2015 dependent on Corrosion Resistancy Class (see ETA sect 3.1).

Design

• Anchorages are designed under the responsibility of an engineer experienced in anchorages and façade design.
• Verifiable calculation notes and drawings are prepared taking account of the loads to be anchored.
• Anchorages under static or quasi-static loading are designed in accordance with: EOTA Technical Report TR 062 Design of fasteners for façade panels made of natural stone.

Installation Instruction

• The undercut drill holes are prepared at the factory or on site under workshop conditions. In case of drilling on site, supervision of the person responsible for technical matters of the site or a skilled representative thereof is required
• The undercut drill holes are drilled with a special drill bit according to Table B4. The drill bit should be used with a special HSU ADT/MDT drilling machine. Other suitable drilling machines may also be used.
• The drill dust shall be removed from the drill hole.
• In case of an aborted drill hole, the newly drilled hole must be placed with a minimum spacing of twice the depth of the aborted drill hole.
• The geometry of the drill holes shall be checked in 1% of all drillings. The following dimensions are to be checked and documented following the manufacturer’s instructions and using the gauge in accordance with Table B3.
  • Diameter of the drill hole do,
  • Depth of the drill hole h1.
  • Diameter d1
  • Height of the undercut h2.
• If the tolerances in accordance with Table B3 are not met, the drill hole geometry shall be checked in 25% of the performed drillings. No subsequently checked drill hole may exceed the tolerances, otherwise all drill holes shall be controlled. Drill holes not meeting the tolerances shall not be used for anchor installation.
  • Note: Checking the drill hole geometry of 1% of the drill holes means that on one out of 25 slabs with four drill holes in each slab (100 drill holes) one drill hole shall be checked. If the tolerances given in Table B3 are not met, then the control shall be increased to 25% of the drillings e.g. one drill hole on each of the 25 slabs.
• During transport and storage on site the façade panels are protected from damages. The façade panels shall not be mounted with jerking motions to avoid damage to the panels. If necessary, lifting devices can be used. Façade panels or reveal slabs with incipient cracks shall not be installed. Overhead installation is allowed.

Table B2: Properties of natural stone panels

1. Minimum panel thickness is equal to the lower limit of tolerance.
2. For sandstone, limestone and basaltic lava: panel thickness ≥ 30 mm, if the panel manufacturer warranted lowest expected value (5 % fractile) of the flexural strength is < 8 N/mm?.
3. For small fitting or fill-in pieces the minimum edge distance or spacing shall be chosen according to the geometrical boundary conditions. In case of design under static loading using FEM, smaller edge distances are allowed.
