how to avoid vertical joints of a stretcher course

Clarification: A queen closer is a brick piece cut in half along the length. It is placed so as to avoid vertical joints. It makes the header come centrally above the underlying stretcher.

Full Answer

How to use header and stretcher in alternate courses?

(5) In thick walls the middle portion is entirely filled with header to prevent the formation of vertical joints in the body of the wall. (6) Since the number of vertical joints in the header course is twice the number of joints in the stretcher course, the joints in the header course are made thinner than those in the stretcher course.

How to break vertical joints in the successive courses?

In order to break the vertical joints in the successive courses, it is essential to place queen closer after the first header (quoin header) in each heading courses. Also, only headers are used for the hearting of thicker wall. The essential features of English bond are. Alternative courses will show either headers or stretchers in elevation.

What are the rules of stretcher bonding?

Jul 07, 2015 · The vertical joints in the alternate courses should be along the same vertical axis. Rule-6. The stretcher should be used only in the facing; they should not be used in the hearting. Hearting should be done in headers only. Rule-7. It is preferable to provide every sixth course as a header course on both the sides of the wall. Rule-8. Use of raked and other joints that provide …

Can a stretcher be used in the hearting?

Nov 30, 2015 · • Vertical joints in alternate courses should be in a single plumb line. • Header should be exactly in the middle of stretcher in two consecutive courses. • Brick bats should be avoided to the maximum. 4. Types of bonds: 1. Stretcher Bond 2. Header Bond 3. English Bond 4. Flemish Bond 5. Facing Bond 6. English Cross Bond 7. Brick On Edge Bond 8.

What is provided to avoid continuous vertical joints in English bond?

8. What should be placed at the beginning of every header course in English bond to avoid vertical joint? Explanation: A queen closer is a brick piece cut in half along the length. It is placed so as to avoid vertical joints.

Which is placed for breaking the vertical joints in the successive courses?

In order to break the vertical joints in the successive courses, it is essential to place queen closer after the first header (quoin header) in each heading courses. Also, only headers are used for the hearting of thicker wall. Alternative courses will show either headers or stretchers in elevation.Mar 3, 2012

What is the reason for avoiding a continuous vertical joint in construction?

The rule is, “Vertical joints of the successive courses of bricks should not coincide, that is, a continuous vertical joint across the wall should be avoided since it will gradually result into cracks development.” The strength and stability of the wall is less as compared to the properly bonded brickwork.Dec 29, 2011

What is a vertical bond?

1. In brickwork, a pattern bond; the facing brick is laid with all vertical joints continuously aligned. The brick is bonded to the backing by metal ties. 2. In stone veneer masonry, a pattern in which units of a single size are set with continuous vertical and horizontal joints.

Which bond is stronger English or Flemish?

The difference between English bond and Flemish bond are as follows: English bond is much stronger than flemish bond for the walls thicker more than 1½ brick. Flemish bond shows more attractive and pleasing appearance of masonry work.

Where is Flemish bond used?

The main purpose of using single Flemish bond is to provide greater aesthetic appearance on the front surface with required strength in the brickwork with English bond. Double Flemish Bond has the same appearance both in the front and back elevations, i.e. each course consists of alternate header and stretcher.

How do you avoid vertical joints in Flemish bond?

As shown in the figure above, the vertical joints come over each other. This is also followed by the vertical joints of the stretcher course. The vertical joints are broken to avoid the joints to form inline, by using a queen closer. The queen closer is placed after the quoin header for each heading course.Nov 29, 2019

How are construction joints treated?

The surface of all construction joints must be cleaned, and all laitance must be removed. Before new concrete can be placed, all construction joints must be wetted, and all standing water shall be removed. The strength of a structure must not be impaired by construction joints.

How do you stop walls cracking?

Build in movement joints as construction proceeds. Spacing between these joints should never exceed 15m in unreinforced walls. Use slip planes - these enable elements of the construction to slide in relation to each other to help reduce stress in the adjacent materials.Nov 17, 2015

What is stack bond?

The stack bond is made up of courses of stretchers where each stretcher is stacked directly above a stretcher and the joints align. This is not a structural bond and is generally used on interiors for non-load bearing walls.May 16, 2021

What is horizontal bond?

The horizontal lines represent bonds that project out of the plane of the paper, towards the viewer, and the vertical lines represent bonds that project behind the plane of the paper, away form the viewer.Mar 12, 2022

What is a running bond pattern?

Running bond is a technique for laying out patterns made with masonry bricks or stone blocks. The width, height and textures of the bricks and blocks vary widely; it's the way they're laid out that creates the running bond pattern.

What is stretcher bond?

A Stretcher Bond is a simple and easiest bond to work with and bricks are staggered by half brick from the course above and below in a classic one over two patterns. All bricks are laid lengthwise, with the long sides facing out, recommended for walls of half brick wide.

What is load bearing wall?

Load Bearing Wall. It is a wall that will bear all the weight of the house. The materials used to construct load-bearing walls in large buildings are concrete block or brick. It helps in separating spaces and also provides support for anything that is above them.

How are bricks laid?

The bricks are laid in one stretcher and one header courses alternately. In the stretcher course one brick each is laid as a stretcher at the front and the back of the wall and a pair of bricks is laid as headers between them. They are usually used as a load-bearing wall carrying the weight of a slab.

What is bonding in masonry?

A bond is an arrangement of masonry units in successive causes to tie the masonry together, both longitudinally and transversely. The arrangement is usually worked out to ensure that no vertical joint of one course exactly over the one in the next course above are below it, and there is a maximum possible amount of lab.

How thick is half brick?

Half brick wall referred to as 115 millimeters thick wall. The thickness of a wall equal to the thickness of a brick’s width. Ensure no two successive vertical joints fall in one line along with the height of the wall. They’re generally used as internal partition walls.

What is bonding brick?

Bonding provides strength and stability to the brick structure. A properly bonded wall can receive a heavy load and will distribute the load over a large number of bricks, which in turn will distribute the load over a larger area of ground.

How thick is a brick wall?

Full brick wall referred to as 230 millimeters thick wall. A wall having a thickness equal to the length of a brick. At the ending of the wall, a half-brick is used to avoid vertical joints falling in the same line.
