Solar – Was darf auf bzw. an FischerTHERM Sandwichelementen befestigt werden? Für eine Einleitung von Einzellasten bei Sandwichelementen ist eine Zulassung für tragende Sandwichelemente erforderlich. Hierin werden Lastverteilungs-breiten und Linienlasten geregelt. Für die Erlangung der allgemeinen bauaufsichtlichen Zulassung sind Versuche mit den Befestigungssystemen durchzuführen, um somit die Tragfähigkeit des Sandwichelementes selbst unter der geprüften Lasteinleitung ….  Read more

Solarhaltesystem – Welches Solarhaltesystem wird für die unterschiedlichen Fischer Bauelemente verwendet? Viele Gewerbe- und Industriehallen bieten ideale Voraussetzungen für Photovoltaik Anlagen und es gibt eine Vielzahl von Haltesystemen, doch nicht jedes System darf auf alle Bauelemente montiert werden. Diese FAQ zeigt Möglichkeiten von Haltesystemen bei Fischer Bauelementen. Zur Befestigung der PV-Anlagen sind folgende Systeme gängig: ….  Read more

Photovoltaik – Was ist zu beachten? Hinweise für die Planung und Ausführung Solaranlagen sind Bestandteil des Gebäudes und unterliegen damit den Bestimmungen des Bauordnungsrechtes. Hier gelten im Wesentlichen die Landesbauordnung und das Bauproduktengesetz, ggf. ist die Einrichtung der Solaranlage genehmigungspflichtig. Der IFBS und der Qualitätsverband Solar und Dachtechnik (QVSD) habe eine Unterlage „Solartechnik in Metallleichtbau“ ….  Read more

If the solid wall is sufficiently level, one-piece substructures can be used. However, it should be noted that each trade must or may move within the respective permissible tolerances. So carcass works have relatively large permissible tolerances. If the solid wall to be cladded consists of masonry, a permissible unevenness of 10mm applies in accordance with DIN 18202, Table 3, Line 5 "Non-surface finished walls and undersides of ceilings ......  Read more

Zinc is an excellent corrosion protection for steel. Galvanized construction elements are also used in building construction where corrosion stress due to weathering or other moisture influences is to be expected. Nevertheless, even when exposed to moisture without sufficient air supply, the galvanized surface is still subject to certain corrosion attacks which, under unfavorable circumstances, can lead to premature corrosion. The understanding of these processes is especially important when storing and transporting components in packages....  Read more

1. Fischer trapezoidal profiles as roof covering The minimum roof pitch of roof coverings made of trapezoidal profiles should not be less than 3° without cross joints and roof openings and 5° with cross joints and roof openings. In Part 3 of DIN 18807, point 4.9.3 'Precipitation' states in very general terms how the penetration of water in roof and wall systems can be permanently prevented by ....  Read more

In DIN 18807-1 (trapezoidal profiles in building construction - steel trapezoidal profiles) from June 87, tables 1 and 2 list the required corrosion protection classifications for both sides of the trapezoidal profiles when used in various building systems for roof, wall and ceiling. The side of the trapezoidal profiles that must have corrosion protection class I, II or III ....  Read more

Steel substructure: Bolted through the bottom chord: Stainless steel screw with sealing washer ³ Ø 19mm, non-positive connection between trapezoidal steel profile and substructure, high contact force possible to generate sufficient contact pressure of the washer with vulcanized-on neoprene seal, inexpensive short stainless steel screws, screw connection through the upper belt....  Read more

According to DIN 18807, part 1, corrosion protection class II is sufficient for the underside of trapezoidal steel profiles, this is e.g. a 12µm thick polyester coating on top of a galvanised layer. Since the underside of canopies are not subject to any precipitation and thus washed off like normal exterior walls and roof surfaces, aggressive, acidic dirt settles over time. The same applies, by the way, to wall surfaces under canopies that are not exposed to precipitation....  Read more

Cleaning: In spite of all care taken, occasional soiling of the surfaces, especially on the building site, cannot be avoided. In order to keep the additional effort to a minimum, our customers should already consider a few points during installation: Extreme care during work, avoid soiling and damage to the coating layer, especially when lifting it from the stack. Leave the protective film on the construction elements during assembly, but remove it immediately after completion of the work or at the latest 4 weeks after delivery. Remove drilling chips immediately, thus avoiding rusting under the influence of moisture. Remove dirt before it dries (especially tar and bitumen) ....  Read more
