Anchoring for panels – ASP
Tested solutions for prefabricated concrete manufactures
This section includes a variety of different products for connecting panels around the perimeter of the building with the building’s frame:
- Vertical panels, which rest on the girders around the edge, are anchored at the top through the HGP, GP or Seismic GP channels, described in the Concrete Anchorage Systems section. The channel is normally positioned vertically in the panel and horizontally in the girder. Anchorage is completed by bolts and plates.
- Steel boxes are available for horizontal panels to link the upper part of the panel to the pillars. The anchorage box is incorporated into the panel, so that there are no constraints hindering installation of the upper panel.
- 8 kN and 16 kN brackets for horizontal panels. The horizontal panel has its own weight, which cannot rest completely on the panel below. Anchorage of two or more panels with their weight resting on the panel below can be dangerous; if the bottom panel should break, the remaining panels will collapse one onto the other. In the event of an earthquake, shifting of the horizontal joint in the pillar panels would cause both panels and everything resting on them to collapse. ASP brackets allow the weight of the panel to be anchored onto the pillar. Anchorage is adjustable in three directions. ASP brackets have been used in Italy for many years, and have demonstrated great dependability despite earthquakes.
- GL Locatelli created Link-Loc for the manufacture of heat-insulated sandwich panels. Link-Loc is a cylindrical stainless steel connector that is anchored onto the electro-welded reinforcement grid of the surface supported. The opposite end of Link-Loc is anchored to the electro-welded grid in the weight-bearing surface. Each connector has a lift of 1.5 sqm. The system is easy to use in production, and gives the panel sufficient flexibility, without forming cracks on its surface. Termo-Loc calculation software is available for designing the thermal capacity of panels made with Link-Loc. The software is certified as compliant with European regulations.
