aluminum honeycomb core suppliers JOINTING/ FIXING TECHNIQUE
For outdoor use please note:
Use aluminium blind rivets that have been approved for construction with a 5 mm shank diameter and an attachment head diameter of 11 or 14mm.
Please take the thermal expansion of the aluminum honeycomb core suppliers into account (2.415 mm/m/100°C).
To avoid jamming, the hole in the panel must be large enoughto allow for expansion.With the shank of the rivet fitting closely to the edge of the hole, theattachment head must cover over 1 mm of the area surrounding the hole.
Hole gauges are used for centrically drilling holes into the panel andthe substructure and for centrically fitting the rivet.
Rivet attachment jigs are used for fitting blind rivets without jammingallowing for a tolerance of 0.3 mm. Make sure to use rivet attachment jigs and rivets from the same manufacturer, as the height of the at-tachment head according to DIN 7337 may vary.
The clamping thickness results from the thickness of the material tobe riveted plus an additional value of 2 mm to ensure that the closinghead is perfectly formed. In accordance with this clamping thicknessthe corresponding shaft length is determined in the tables providedby the rivet manufacturers.
Important:
During riveting, many factors may have an influence on the exact toleranceof the rivets of 0.3 mm (e.g. rivet head tolerance). We therefore recom-mend that you make a test on a fagade panel. Please always remove theprotective foil around the riveting area prior to riveting.
Blind rivet nuts and boltsof a blind rivet and a nut or bolt (screw).
Blind rivet nuts and bolts are threaded elements performing the function
There are various types of rivet head and materials which can be selec-ted depending on the intended application. The blind rivet nuts or boltsare inserted in blind holes drilled in one side of the aluminum honeycomb core suppliers.Subsequent fitting with a tool is fast and cost-effective.
Due to the minimum shaft length of 11 mm these fixtures can only beused for a panel thickness of 15 mm or more. As a rule, the rivet must
be anchored in the 1mm thick cover sheet.
