Simple and fast repair of two-leaf cavity walls

Simple and fast repair of two-leaf cavity walls

Buildings with façades comprising two-leaf cavity walls are commonly found in northern Germany, England, the Netherlands and Scandinavia, in particular in the case of older buildings. In areas with heavy exposure to wind and corrosion, these façades are often in need of repair. fischer has developed the approval-compliant remedial wall ties VBS 8 and VBS-M especially for this purpose.

Calculation for a replacement connection to a curved substrate

Calculation for a replacement connection to a curved substrate

Whilst there is a clear regulation for calculations for an anchor connection to a straight wall or a right-angled support as set out in Appendix C of the ETAG 001 or TR 029, there are no official stipulations for dealing with fixings to curved surfaces, such as circular supports or circular-shaped walls. If the radius is sufficient, the same procedure as that for a level substrate can be followed by approximation. However, in the case of smaller radii, it is not possible to just follow the same steps.

ETAG 020: Load-bearing capacities of plastic anchors in concrete and masonry

ETAG 020: Load-bearing capacities of plastic anchors in concrete and masonry

Previous national approvals stipulated general values based on DIN bricks. ETAG 020 now requires that the load-bearing capacity is individually calculated for each individual brick. There is, however, help in the case of solid bricks: the load-bearing capacity values of smaller format bricks can also be used for bricks with higher compressive strength and / or larger formats. In all other cases, the specified values are only valid for the brick defined in the approval and its related hole pattern.

Load-bearing behaviour of anchors in steel fibre concrete

Load-bearing behaviour of anchors in steel fibre concrete

Steel fibre concrete is being used more and more often, when statically possible. Unlike reinforced concrete, it can be manufactured in one step, which significantly reduces workload during processing. Anchor fixings for use in steel fibre concrete have until now not been regulated in the ETAG. Here you can read how a range of tests have shown that there is no significant difference in failure loads between steel fibre concrete and normal weight concrete, and how you can safely calculate anchors in steel fibre concrete.

fischer FPX-I: The first mechanical aircrete anchor with ETA approval

fischer FPX-I: The first mechanical aircrete anchor with ETA approval

The ever-increasing requirements with regard to the insulation of buildings, as well as the demand for faster and more economical building techniques is seeing aircrete becoming more and more important. At the same time, the requirements regarding safe and economical fixing solutions for aircrete are increasing. Read more about the fischer FPX-I: the first mechanical aircrete anchor with ETA approval.
