Good morning,
I am currently building a garage, the floor slab is already finished and agreed with me regarding a gate solution: Clear height of 2.13 cm and clear width of 500 cm, sectional door with window band. Length 11 meters As it is an auxiliary storage garage, a low construction is preferred, I am estimating 1.80 meters at the lowest point in the back (I am 1.87, that works), the roof is a panel roof resting on 220 I-beams (building regulations, I cannot change that).
Well, today I unfortunately noticed the problem when calculating the wall heights: The first I-beam is at 2.20 meters where the door is hung, it logically has to be above ground: Door height 2.15 + 0.15 lintel (very optimistic assumption…) = 2.30, plus about 15 cm to the door due to roof slope = height there then 2.45 meters. Including the I-beam with 0.22 and I am at an internal height of 2.67. Then the panel adds about 10 cm to nearly 2.80; then the prescribed fire clearance of 15 cm and I am touching the maximum construction height of 3 meters… my desired and previously planned construction height is well under that at 2.60… annoying.
Alternative 1: (actually optimizing the current situation) - maybe the angle of the sectional door track cannot be mounted at 90° but maybe at 80° or less and thus save construction height. The door does not mind, the track with a different angle would have to exist, bending is rather difficult. That would be the simplest.
Alternative 2: Side sectional door, which probably only brings a few cm in the lintel and no more, I still have to get through under the I-beam with the side sectional door – and also under a second one behind it, oh dear.. So rather not an alternative.
Alternative 3: Roller door. Would initially be ruled out because I want a window band, since I may only have windows on 2 sides and one long side of those is at a carport. A window band is possible with that, but rather bad and expensive. But it would be an option.
Is there perhaps some flaw in my thinking? What options would (still) be sensible given the situation?
Thank you very much,
best regards Oliver
