What is a half - brick wall?
What properties does a half -brick wall have?
Motivation phase
Half-brick walls in half-brick bond.
The picture shows a half-brick wall. The masonry bond is also half-brick.
What do you notice about the butt joints?
Information phase
Properties of half-brick walls.
> This is a wall that has the thickness of the head, the width of the stone, about half the length of the stone.
> The bricks are bricked together lengthwise.
> Mostly applied for facades of family houses, apartment buildings, etc…
> A half-brick wall can be masonry with either regular bricks( facing brick), quick build brick, concrete blocks and slicate brick.
* The picture shows a half-brick wall in qiuck-block brick. Four of my students bricked this wall.
Information phase
Types of corners in half brick walls:
* Right angle:
> A right angle must always be 90°.
> - Checking squareness can be done using a store hook, a construction hook, by the 1-2-3 rule, by measuring in the opposite direction and by the Pythagorean theorem.
* : Continuous wall:
> The front side of the at a right angle wall, is the continuous wall, the other side is the approaching wall.
* Meeting in half-brick wall:
> In the process, a wall is bricked in at right angles to another wall.
> This meeting should form 2 right angles of 90°
* Implementation:
- This can be done in 2 ways
- * Method one:
> The layers run in turn
> On each side of the header a three-quarter stone( 3/4stone- should be placed to maintain the masonry bond.
> The head of the meeting wall disturbs the stretching layer.
* Method two:
- The layers run in turn.
> The 2 triples are bricked side by side in the continuous layer, not next to the head.
> The head of the meeting wall disturbs the stretching layer.
> This one is almost not implemented.
** The following illustration is an example of a right angle.
