1 HALFEN HIT INSULATED CONNECTION HIT-PAT 15-E CONCRETE NEW! Insulated connections for corbels, all types of parapets, and also for horizontal loads Product range available in insulation thickness 80 mm or mm Fire resistance class REI (F) as standard

2 Be on the safe side. We take fire protection seriously. The fully enclosed HIT-HP and HIT-SP ensure compliance with the highest fire safety requirements in accordance with REI according to EN as well as classification F-AB according to DIN 4102 in compliance with ETA-13/0546 and numerous other approvals. This is made possible by the special shape of the insulation in combination with the use of high-quality non-flammable mineral wool, Building Material Class A1 and Euro Class A1, respectively. Circumferential fire barrier as an efficient fire stop in the insulation layer with full balcony integration Additional fire protection measures, e.g. circum ferential fire barrier or additional lintel fire protection, must be provided to increase the fire resistance of an external thermal insulation composite system using expanded polystyrene (EPS). The HIT-HP and HIT-SP units form a fire barrier in the area of balconies and access walkways, and ensure the necessary fire-retardancy of ETIC-Systems. This reduces additional costs for fire prevention. Installation detail: HIT-HP and HIT-SP units as part of a fire barrier

31 HIT-HP MV-OT, HIT-SP MV-OT Determining the axial spacing a Calculation of the maximum element spacing of the HIT-OT elements is dependent on the acting shear forces +v Ed [kn/m] and the axial forces ±n Ed [kn/m]. Step 1: Step 2: To find V Rd (N Rd ) in the table Load bearing capacity values in order to select shear bars of either 6 mm or 8 mm is dependent on the element height h, the concrete strength class and load distance x. Calculating the element spacing a a max,1 = V Rd /v Ed [m] a max,2 = N Rd /n Ed [m] a = min (a max,1 ; a max,2 ) Step 3: Checking the calculated load bearing capacities (per element). (optional) v Ed a = V Ed V Rd n Ed a = N Ed N Rd a 125 Corbel Main slab 80 HALFEN Website Our website has now been optimised for smartphone access. Scan the QR code to go directly to the website.
