What is a lintel and its purpose?
Lintels are additional supporting structures, which are found above doors and windows. They are essentially load-bearing structures made from timber, steel, concrete or other types of stone. They can also be decorative; however, they must support any heavy loads above the door or window.
What is the purpose of lintel in a building?
A lintel is one type of beam which used to support the above wall when openings like doors, windows etc. are necessary to provide a building structure. The main function of the lintel is to take loads coming from above wall and transfer its load to the side walls.
How many types of lintels are there?
There are 7 types of lintels used in buildings. RCC lintel, Concrete lintel, Steel lintel, Brick lintel, Timber lintel, Stone lintel, and Flitched lintel.
What is the difference between a header and a lintel?
As nouns the difference between lintel and header is that lintel is (architecture) a horizontal structural beam spanning an opening, such as between the uprights of a door or a window, and which supports the wall above while header is the upper portion of a page (or other) layout.
Are lintels required?
Lintels. If an opening is formed in a wall, the structure above the opening, even if it is relatively small, will need to be supported. One lintel (usually made of steel, with insulation integral to it) that supports both the inner and outer leaf of a cavity wall construction.
How does a lintel work?
A lintel is a beam placed across the openings like doors, windows etc. in buildings to support the load from the structure above. The width of lintel beam is equal to the width of wall, and the ends of it is built into the wall. Lintels are classified based on their material of construction.
Why do lintels fail?
The most common reasons for lintel failure are faults with the lintel such as the corrosion of the steel. It’s important to note that lintels may be cracked or blown due to other structural issues such as movement in the wall or foundations.
What is meant by lintel level?
What is Lintel Level? The height measured from floor level above the ground to the window top- level refers to the lintel level. Or level above the window is known as lintel level. or A level at which the door and window top are finished is called lintel level.
What is the difference between lintel and beam?
The beam carries the load from slab and transfers it to the column from, column it is transferred to the footing and from footing finally to the soil. Whereas lintel carries the load of the wall above the openings and transfers it to walls only.
What is the most common lintel material?
The most common materials for lintels are timber, steel and concrete.
- Timber is low cost, readily available and can be easily cut to size on site.
- Precast concrete lintels are economical and provide robust support for structures such as masonry over door and window openings.
How do I choose a lintel?
Lintel selection: A step-by-step guide
- Step 1 – Establish the construction material. Understanding wall construction is vital to lintel selection.
- Step 2 – Determine the opening width and cavity width.
- Step 3 – Calculate the load incorporating triangulation.
- Step 4 – Interpret the load span tables and ratios.
- Step 5 – Selecting the correct lintel.
Which type of lintel is used in small opening?
Brick Lintels It can be formed as bricks on end, bricks on edge, and coursed bricks laid horizontally over openings. This type of lintel is used when the opening is small (less than 1m) with light loadings. Their depth varies from 10 cm (thickness of one brick) to 20 cm depending upon the span.
What’s a header in construction?
A header in the construction and engineering world is a beam over an opening that disperses the structural load to the outside of the opening to keep structural integrity. The header beams the load from above and disperses it to the outside edges of the opening.
Is a header the same as a beam?
A header is a beam that spans the opening for a doorway, window, skylight, or stairway. In general, workers in the construction industry refer to large beams as girders. If it is the chief horizontal support in a structure, it is a girder, not a beam. If it is one of the smaller structural supports, it is a beam.
What size lintel do I need for a door?
Measure the size of the open space between the walls where the door /window frame is fitted. Add a minimum of 150mm to each end. For example, for a structural opening or clear span of 1,800mm, the minimum lintel length required will be 1,800 + 150 + 150 = 2,100mm.
