I or H bricks or tiles with dowels for stronger, lighter assembled structures
From the engineering consideration that regular tiles and bricks are far from optimal in terms of adding strength to structures, I've been considering that better would be this very particular 2D pattern of tiles and bricks illustrated in this image which I first posted in a topic in Caithness.org's Photography forum, Tessellated I - my simple technical drawing, coloured artfully

Representing a surface of "I"-shaped (rotated by 90 degrees, "H"-shaped) steel tiles. The shape is of square proportions, the column of the I being one third of the width of the square and the top and the base one quarter of the height of the square.
Here is an I-tessellation in paving stones -

But my pattern of I or H tiles or bricks is very specifically designed so that it can be developed into a more detailed 3-D design which introduces further efficient tile-to-tile / brick-to-brick interlocking or making-rigid features which solve some of the limitations and issues arising with structures made from conventional bricks and tiles.
Conventional brickwork structures need a weaker mortar layer to hold a brick wall together - http://nancymorris.com/wp-content/up...Brick_Wall.jpg
Conventional tiled structures need to stick tiles onto a mounting surface - http://www.granitetransformations.co...steel-tile.jpg
These limitations of those brick-to-brick or tile-to-tile bonding methods make for weaker and heavier brick and tile structures than is ideal in some engineering applications.
In particular for temporary brick or tile structures, a high strength to weight ratio is desirable so that the parts of the structure can be moved easily to where they need to be erected.
In addition, temporary structures need the ability to disassemble the structure as easily as it was assembled.
We see examples of ease of disassembling a structure with kids building toys such as Lego and Meccano and in many manufactured products which use such typical features as nuts and bolts and bolt-holes but many other variations to secure one part to another strongly but in a reversible and flexible way. http://www.thedailygreen.com/cm/thed...-bricks-md.jpg
So with those requirements in mind, my 2D I / H tessellation pattern was designed with a view to a 3D design of structures which I will now specify and show you a model to help me explain my 3D design more clearly.
