What is stretcher in brick masonry?
1. Stretcher bond – Longer narrow face of the brick is called as stretcher as shown in the elevation of figure below. Stretcher bond, also called as running bond, is created when bricks are laid with only their stretchers showing, overlapping midway with the courses of bricks below and above.
- Stretcher bond in the brick is the simplest repeating pattern.
- But the limitation of stretcher bond is that it cannot make effective bonding with adjacent bricks in full width thick brick walls.
- They are suitably used only for one-half brick thick walls such as for the construction half brick thick partition wall.
Walls constructed with stretcher bonds are not stable enough to stand alone in case of longer span and height. Thus they Then need supporting structure such as brick masonry columns at regular intervals. Stretcher bonds are commonly used in the steel or reinforced concrete framed structures as the outer facing. Fig-1: Stretcher Bond
What is the difference between stretcher wall and header wall?
Now let us move on with our brief discussion on “Header Bond”. –
The square face of the brick which measures (9cm x 9cm x 9cm) is called as “header”.
When all the bricks are placed as headers on the faces of the walls, the bond formed is called “Header Bond”.
Header Bond in Elevation
Stretcher bond is used for the construction of walls of half brick thickness whereas header bond is used for the construction of walls with full brick thickness which measures 18cm.
Header bond is also known as heading bond. The overlap is kept equal to half width of the brick. To achieve this, three quarter brick bats are used in alternate courses as quoins.
Isometric View of Header Bond. The bricks that are highlighted in dark brown colour are called “Three quarter Brick bats”.
Since header bonds lacks strength in pressure transmission along the length of the wall, it is not preferable to use this kind of bond for load bearing walls.
Header bond is useful when the design demands curved surfaces to be constructed. In such cases, stretcher bond cannot be used. Apart from using it for curved surface, it can also be used for the brickwork in foundations.
So here we come to the end of the discussion on Header Bond and Stretcher bond. In our next article, we will discuss “English Bond” in detail. : Types of Bonds in Brickwork | Stretcher and Header Bond
What is a header called in masonry?
Header. It is a brick or stone which lies with its greatest length at right angles to the face of the work in case of stone masonry header is sometimes known as through stone. The course of brick work in which all the bricks are laid as headers is known as header course.
What is a header in masonry construction?
Summary: What Is A Header? – If you’ve ever tried to do any residential framing then you’ve probably heard the very important term header. In this article we’ll be answering the questions what is a header and when do you need one? A header in construction is a beam installed over an opening which disperses the load placed on top to the sides.
- Windows and doors typically have one on top which supports the load above.
- Without the header, weight would be placed on the window or door causing damage and/or total failure.
- On the sides of the header-beam are framing members called king and jack studs.
- They transfer the load placed onto the beam down to the foundation.
As long as the opening is framed correctly, no weight will bear on the window, door or whatever else you place inside. Headers are a very important part of framing. Without them, builders wouldn’t be able to span distances or create voids for things like windows and doors.
Header-beams are only needed on structural load bearing walls where weight will be placed on top of the void. Non structural walls usually don’t require them because there’s almost never weight placed above the opening. If there was, the wall would be considered load bearing. Headers are sized based on both the length of the opening and the load.
Then the architect also sizes the king and jack studs which support the header. If you have any questions about framing, any time. : What Is A Header? (Understanding Construction)
What is header and stretcher?
While Stretcher bond is used for the. construction of walls of half brick thickness whereas header bond is used for the. construction of walls with full brick thickness which measures 18cm. In header. bonds, the overlap is kept equal to half width of the brick.
What is stretcher used for?
A stretcher is a long piece of canvas with a pole along each side, which is used to carry an injured or sick person. The two ambulance attendants quickly put Plover on a stretcher and got him into the ambulance. If someone is stretchered somewhere, they are carried there on a stretcher.
What is header in walls?
So What is a Header? – 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.
- In this case, the wall in which a header is placed is load-bearing.
- There are trusses that are imposing a roof load over the opening that we want to create.
- The load onto the header has to be transferred around the opening.
- The header beams the load from above and disperses it to the outside edges of the opening.
Headers are sized based on the length of the opening and the load. From there, we decide what kind of post is necessary. Here you can see the load is dispersed to the side of the opening and we have two posts.
A king stud.Jack stud (or trimmers) – where the load is actually placed or transferred
The load path goes down the jack stud to a single bottom plate and down to the foundation. This king stud completes the assembly to keep it ridged. The number of jack studs and king studs is calculated based on the load. So there you have it, headers 101.

What is a stretcher wall?
Stretcher Bond – Stretcher bond, also called as running bond, is created when bricks are laid with only their stretchers showing, overlapping midway with the courses of bricks below and above. Ad. Stretcher bond in the brick is the simplest repeating pattern.
What is the thickness of stretcher bond?

|10 cm thick means brick laid with along the length of wall. which Means by viewing the front side of the wall, You see the stretcher side of the brick. Hence thickness has to 10 cm.|
