What size are concrete lintels?
Concrete lintels are available in a range of lengths including: 600mm, 900mm, 1200mm, 1350mm, 1500mm and 1800mm.
What is the minimum thickness of lintel?
The width of the lintel can be equal to the thickness of the opening & depth in the range between 1/12 to 1/8 of the span. Minimum width of lintel 4 inches (100 mm) should be provided.
What type of concrete is used for lintels?
Because of their rigidity, strength, durability, fire resistance and aesthetics, the most common types of lintels for concrete masonry construction are those manufactured of precast reinforced concrete or reinforced concrete masonry units (ref. 3).
What weight can a concrete lintel take?
A 900mm SL50 has a height of 95mm, and weighs 6.2kg per metre. Looking at SWL figures you can see that if your floor load is a 1:1 ratio (so the same weight is applied on both the inner leaf and outer leaf, then this SL50 at 900mm can take a load of 8kN on each leaf.
How do you calculate lintel thickness?
Calculation of size depth and width of lintel:- suppose we have given opening is equal to 1 metre and end bearing 200mm at both end with 9 inch thick brick wall, width of lintel is equal to thickness of wall, so width of lintel is equal to 9 inch and lintel depth should be L/12, effective span L=1+0.2+0.2=1.4m, so …
How do I know what size lintel I need?
What Size Lintel Do I Need?
- STEP 1: KNOW YOUR WALL CONSTRUCTION.
- STEP 2: KNOW YOUR LENGTH. How wide is the structural opening? Measure the size of the structural opening i.e. the clear span between the Masonry supports.
- STEP 3: KNOW YOUR LOAD. You need to know the load in which the Lintel will support.
Can I make my own concrete lintel?
Despite what has been said it is quite feasible to do your own concrete lintel as it’s basically a reinforced concrete beam that isn’t prestressed. Having said that because lintels are prestressed they can be made smaller in size whilst giving you the same strength.
