Three brickwork tutors say this is stucturally sound and correctly bonded

so it should work ...

And now for the Maths!


Drawn by Anne Jan '11

The drawing shows some corbelling. Note that only the left-side is properly bonded. The right-side would need ¾ cuts

The 1st course is one brick wide, or 215mm, which is the same as two headers, plus 10mm joint

The 2nd course is increased by a Queen Closer + 10mm



Look carefully at the drawing and you'll see there are two perp-joints in the 2nd course

So the 2nd course is two Headers, plus their 10mm joint and then a Queen Closer, plus its 10mm joint

As can be seen the Size of a Queen Closer is 46mm

Calculating length of 2nd Course

Header          102½
Perp Joint        10
Queen Closer   46
Perp Joint        10
Header          102

Total             271mm

Difference between 2nd course and 1st course

271 minus 215 = 56mm

so the corbelling on each side is 56 divided by 2 = 28mm


Drawn by Anne Jan '11
From the picture, you can see the 2nd course has gained a Queen Closer and a 10mm joint

46 + 10 = 56mm

The 3rd course is 1½ bricks or one stretcher with its joint, and one header

225 + 102½ = 327½




Double-Check

Difference between 3rd course and 2nd course

327½ minus 271 = 56½mm

Which is good enough for me!


Drawn by Anne Jan '11
As can be seen, the 4th course is 1¾ bricks

And the 5th course is 2 bricks

which is 440mm
1st Course   = 215

2nd Course  = 271

3rd Course   = 327½

4th Course   = ? ? ?

5th Course   = 440

What is the size of the 4th Course?

It is in the middle of the 3rd and 5th course

440 - 327½ = 112½

112½ divided by 2 = 56¼

327½ + 56¼ = 383¾

Martin



Brickwork panel designed by Anne. Oct '10
Shaded bricks indicate the cuts


The design was adapted
from Patterns in Islamic Art


Photo taken 5th Nov '10
Martin is building a decorative panel. The brickwork is
single-skin and constructed from one-third, two-thirds
and full-length bricks


Photo taken 12th Nov '10
The back of the panel is built up from blocks, which are bonded into the brick pillars. Because of its height, there is also an attached pillar of blockwork, to provide extra stability

When I was given this task I felt like I couldn’t do it, it looked so difficult. Everyone thinks it’s easy but that’s not right

First you must read the plan properly, making sure everything’s right. Secondly is to make sure the area is right for the brickwork. It’s no good just starting to lay bricks as that will be wrong

Take your tape measure and check out the area, checking how high the wall is and making sure it will fit in. Next you must think about all the area around you as you will need plenty of space for bricks, blocks, spot board and some space for you to work in. If you have a small space and you can’t properly turn around, it’s not safe and could be dangerous – which would be a bad move

How to make wall stronger

Alright, I don’t mean putting glue in the cement or something, you can make the wall stronger with blockwork. The blockwork is built between the brick wall with block pillar bonding to make it strong, safe for you and people around you and to prevent it from falling over

This is looking fabulous!

Strap-work

This design is a combination of soldiers and stretchers and needs a volunteer to build it


Image drawn by Anne
It reminds me of Strapwork, see below


Image from: Bailey & Hancock (1979) Brickwork Volume 3 page 26
Strapwork is often used on ceilings or furniture, but can be seen in timber or stone panels


Such carvings can become very elaborate

Decorative Panels

Over the past few weeks, some of you may have noticed me building walls at the back of the workshop


Photo taken 26th May '10
These are just prototypes, built to determine the best bonding arrangement to ensure the blockwork is securely tied into the brick pillars


Photo taken 15th June '10
Next year, they will be a permanent fixture, and so provide an opportunity for you to have a go at some decorative brickwork.


Photo taken 16th June '10
This drawing shows the Front Elevation of the panel. Bricks for the pillars are shaded in light grey and the blocks in dark grey. Bricks shown in white are the three courses of English Bond which form the base

The last course is unfinished because this row of stretchers will run across the top of your decorative work


Image drawn by Anne
The bonding detail is shown below in the Plans for each course. The top courses are shown first, while those at the base of the panel are shown last

To complete the course, the brick pillar on the right needs finishing. To increase stability, only full-blocks are used in this design

Michael's Panel

This decorative bond is called Diagonal Herring-Bone
First the pillars were built up - to gauge, level and plumb


Photo taken 10th June '10
Then, the first few courses were laid. Notice the use of more than one line


Photo taken 10th June '10
Although the pillars should have been built-up to their full height,
it was nice to see what this decorative bond looked like


Photo taken 10th June '10
The following week, the rest of the supporting pillars were built


Photo taken 17th June '10
During the construction, we realised the importance of the blockwork at the back


Photo taken 17th June '10
Michael was joined by his mate, Jason and this task was completed on the second day

These Level 1 students only started college last year

The finished panel, being pointed. Well done, lads!
