Readers ask: What Is A Lintel In Construction?

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.

What is the difference between a beam and a lintel?

The function of the beam is to support the slab resting on it. It also provides support for the floor and ceiling. Whereas the main function of the lintel is to support the masonry wall above the openings like the door, window and transfer its load to sidewalls.

What is the difference between a header and a lintel?

The lintel is a horizontal structural beam that extends over an opening, like between the heights of a door or window, and keeps the wall at the top. A header is a brick that lays sideways at the top of a wall with the short side facing outward.

Are concrete lintels stronger than steel?

Strength. It is not a myth that steel lintels are stronger than concrete; this is generally the case, but it is a little more complicated. A high strength prestressed concrete lintel can often offer better supporting properties than a similar steel version at certain lengths and can be considerably cheaper.

How do you calculate a lintel?

Also, the length of lintel in case of masonry wall is calculated by taking the measurement of the total width of the opening and adding 150 mm for end-bearings at each end. In a house, the level of lintel is generally the soffit level of a door or window.

Is a lintel required?

Lintels are required for all openings over timber frames greater than 600mm in width, & for all openings over steel frames greater than 900mm.

What does lintel mean?

: a horizontal architectural member spanning and usually carrying the load above an opening.

How thick should a lintel be?

Steel angle lintels should be at least 1/4 in. (6 mm) thick with a horizontal leg of at least 3 1/2 in. (90 mm) for use with nominal 4 in. (100 mm) thick brick, and 3 in.

What is the strongest beam shape?

The most efficient shape for both directions in 2D is a box (a square shell) however the most efficient shape for bending in any direction is a cylindrical shell or tube. But, for unidirectional bending, the I or wide flange beam is superior.

What are the three types of beams?

Beams may be:

  • Simply supported: that is, they are supported at both ends but are free to rotate.
  • Fixed: Supported at both ends and fixed to resist rotation.
  • Overhanging: overhanging their supports at one or both ends.
  • Continuous: extending over more than two supports.
  • Cantilevered: supported only at one end.

Is a lintel a beam?

A lintel is a beam placed across openings like doors, windows etc. in buildings to support the load from the structure above.

What are steel lintels used for?

A lintel is a structural horizontal support used to span an opening in a wall or between two vertical supports. It is frequently used over windows and doors, both of which represent vulnerable points in a building’s structure. Lintels are generally used for load-bearing purposes, but they can also be decorative.

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. Otherwise, the load from the roof, floor, or whatever is above the opening can lead to stress that can cause cracks, shifting, or even worse.

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.
