Types of Bonds in Brickwork

BOND OF BRICK IN MASONRY WORKS

Types of Bonds in Brickwork:

The masonry wall in which bricks are used are known as brick masonry wall. Following are some bonds in brick masonry wall work described below –

1.       Stretcher Bond

2.       Header Bond

3.       English Bond

4.       Flemish Bond

5.       Garden Wall Bond

      STRETCHER BOND:-

a)      In this type of bond all bricks are arranged in the stretcher course.

      HEADER BOND:-

a)      In this type of bond the bricks are arranged in header course.

      ENGLISH BOND:-

This type of bond is generally used in practice. It is considered as the strongest bond in brick work.

a)      The alternate course consists of header and stretcher.

b)     The Queen Closer is put next to the header to develop the face lap.

c)      Each the alternate header is centrally supported over a stretcher.

d)     If the wall thickness is an even multiple of half brick the same course show header or stretcher in both the front and the back elevation, but if the wall thickness is an uneven multiple of half-brick a course showing stretcher on the face, shows header on the back and vice versa.

e)      The brick in the same course don’t break joints with each other. The joints are straight.

f)       In this bond the continuous vertical joints are not formed except at certain stopped end.

g)      The number of mortar joint in the header course is nearly doubles tan that in the stretcher course.

Hence care should be taken to make the header joints thinner; otherwise the face lap disappear quickly.

h)     A header course should never start with queen closer. As it is liable to get displaced in the position.

i)       The Queen Closer are not required in stretcher course.

      FLEMISH BOND:-

In this type of bond the header are distributed evenly and hence it creates the better appearance than English Bond.

a)      In every course header and stretcher are provided alternately.

b)     The Queen Closer is put next to the header in alternate course to develop the face lap.

c)      Every header is centrally supported over a stretcher and below it.

d)     The Flemish bond may be divided into two parts –

                                                         i.            Double Flemish Bond.

                                                       ii.            Single Flemish Bond.

i.                     Double Flemish Bond:

In double Flemish Bond the header and stretcher are placed alternately in front as well as back elevation.

ii.                 Single Flemish Bond:

In single Flemish Bond the face elevation of Flemish Bond and the filling as well as backing is of Flemish Bond.

e)      The brick in the same course don’t break joints with each other. The joints are straight.

f)       In this bond the shocked continuous. The vertical joints are formed.

g)      The bricks beds are to be used for walls having a thickness equal to or even number of a half brick.

      GARDEN WALL BOND:-

a)      This type of bond as the name suggest is used for the construction of boundary wall, compound wall, garden wall etc.

b)     The wall is one brick wall and its height does not exceed 2.0m.

c)      The wall may be constructed either English Bond or Flemish Bond.

d)     In the English Garden Wall Bond, one header course is provided to three or four stretcher course.

e)      The Queen Header are placed in alternate course and a Queen Closer is placed next of Queen Header in a header course to developed the necessary lap.

f)       In the Flemish Garden Wall Bond, each course contains one header to tree or five stretchers.

g)      A three forth brick bed is placed next to the Queen header in every alternate course to developed the necessary course.
