Basic knowledge of fastening technology Fire protection in fastening technology. The fastening technology has a vital importance in fire protection. To ensure the functional capability and stability of railings, pipe systems, fire safety doors or ceiling elements. Assessing fixings for fire is carried out in accordance with the technical regulation EOTA TR020 or in accordance with fire protection reports. The labelling and classification of anchors and fixings is classified in: 1 Fire behaviour (e. g. non-flammable) 2 Fire resistance duration (e. g. R90) For this purpose, the legal regulations set down in the final draft of the Delegated Act "Fire Behaviour" must be observed. Before the fire test EOTA TR020 only states anchor performance ratings that have an ETA for cracked concrete! Meanwhile, a new evaluation document issued by the German Institute for Construction Engineering (DIBt) is used to determine the characteristic load values and the corresponding fire resistance duration. A partial safety factor of γM = 1.0 on the load side is used in the event of fire. 16 The fire values only refer to anchor bolts that are directly exposed to flames. Alternatively, anchors can be protected from direct exposure to fire by using fire protection panels or fire protecting coatings. During the fire test After the fire test 658 For fixing cladding systems, it is assumed that the load bearing capacity of specified plastic screw anchors in concrete with an external diameter of 10 mm and a metal screw diameter of 7 mm and an anchoring depth of hef = 50 mm with a polyamide PA6 plastic sleeve has a sufficient fire resistance of at least 90 minutes (R90), if the permissible load (no permanent centric tensile load) is ≤ 0.8 kN.
