Hi All,
This is my first post but a long term lurker, and found this site very useful.
I'm planning on installing some lintels in a single skin (6in block) garage wall and after looking around at the various places with span tables and specifications im a bit confussed as to what value i should be paying attention to to get the correct load?
I'd like to use R15 lintles as they can be used on their side and will fit the block nicely but want to be sure that it will be upto the job on the biggest opening (1.5m).
My engineers report says the lintel in question will be under the following load:
Deadload
Wall = 2.6 kN/m2 x 1.500m / 2 = 1.95 kN/m
Garage roof = 1.3kN/m2 x 6.200m / 2 = 3.97 kN/m
Total DL = 5.92 kN/m
Imposed Load
Garage roof = 0.6kN/m2 x 6.200m / 2 = 1.86 kN/m
So i'm assuming that the total load combined would be 7.78 kN/m
I run into trouble when looking at what a R15 is capable of one source says load baering capacity of 18.45 kN/m another says a UDL of 9.5 kN/m a thrid source says though a slightly differnt product (Naylor R3) specifies an Unfactored Load of 12.38 kN/m
Which of these values do i need to pay attention to when taking my engineers calculations into consideration?
Thanks in advance,
Gregg
