What is English Bond and Flemish Bond ?
Both is the arrangement of bricks in each layer so as to avoid the continuity of vertical joints in any two adjacent courses, both on the face and inside of a masonry structure. As well as In this, English Bond and Flemish bond mostly use in the construction of the walls.
English Bond and Flemish Bond are discuss are below :-
- A queen closer must be place after the quoin header in the header course for breaking the continuity of vertical joints.
- Every alternate header in the header course should be centrally place over a stretcher.
- There should be no continuous vertical joints except at stop ends.
- The wall shall show same appearance on both faces when its thickness is equivalent to multiple of half bricks.
- Wall shall show stretcher on the face and header on the back or vice-versa if its thickness is equivalent to odd multiple of half bricks.
- The hearting of the thicker walls should consists of only headers.
- The joints in the header course should be made thinner than those in the stretcher course because twice the number of joints are provide in the heading course than in the stretching course.
- The stretchers and headers are lay alternately on the front and the back faces in the same course.
- The header in every course is in the center of a stretcher of the underlying or overlying courses.
- Queen closer are provide after every quoin headers in alternate courses to break the continuity of vertical joints in successive layers.
- Brick bats are use in walls having thickness equal to an odd number of half bricks.
