From here, you work in the real
size. It should be known that Zome, like any construction, will
take time and a little money. My goal is that all that is at least
The structure is essential, well done it will be very rigid and durable. For the remainder, you can take some freedom, especially if you have tried out the self-help housing.
|You made a model and played well
with; to continue in the real face, it is to better know what
will be your project: cant or shelters, or element of dwelling,
that will condition some details of construction
Approximately, one invests oneself more for a habitat, it will have to present guarantees of durability and to ensure comfort (insulation...). For a hut one can be less looking for the etancheïty with the air, the completions...
I propose these dimensions
They are theoretical and interior dimensions in the zome..
dimensions are not appropriate to you, if you find the zome too
large or too small, too low or too high, modify them
B The matos
It is necessary to measure lengths and angles, to cut out and assemble
One can work with tools with hand: saw, hammer, turns screw.
Or electric transportables: circular saw, drilling machine, screw driver
Or heavier: circular saw on table, radial.
Or a combination of these tools, according to what one has
To choose a light, tender and solid wood: the ordinary pine is appropriate, the pine of North or the Douglas one is better
Section: chosen: 110 X 32 (mm) - Important: that all wood are right and have same dimensions If wood is not dry, not to wait
|To notice how the amounts position
For a type of rhombuses, there is a same length and only one angle
with this thickness of struture (32 mm) and this organization
- the width of structure is selected to contain insulator It does not modify dimensions One can choose some another and go down up to 60 mm for a smaller model or a hut
- the thickness modifies dimensions from 25 to 40 mm are appropriate according to wood that one finds (32 X 110 is common)
*** if one adopts the same thickness (32) but other dimensions of zome, the differences between theoretical and real dimensions do not change
*** if another thickness E is adopted, one will calculate the following corrections to remove with theoretical dimensions
amount of rhombus 1: 1,25 . E
amount of rhombus 2: 1,02 . E
vertical uprights of wall: 2,12 . E and 1,62 .E
Does that seem a little complicated? The zome is a mathematical being and if you want a model different from what I propose, some calculations will have to be made
Example: I want a diameter of 5,555 m and the same minimal height of walls (1,90 m) and I have some 38 mm thickness wood
The ratio of scale will be 1,1501 is 1,150 what will give new theoretical dimensions
- a length of edge (rhombuses and high of the walls) of 1,35 . 1,15 = 1,553 m
- a side of zome of 2,777 m
From where like real dimensions
- edge of rhombuses 1: 1,553 - 1,25 . 0,038 = 1,553 - 0,0475 = 1,5055 is 1,505 or 1,506 m
- edge of rhombuses 2: 1,553 - 1,02 . 0,038 = 1,514 m
- vertical uprights of wall: 1,900 - 2,12 . 0,038 = 1,819 m and 1,900 - 1,62 . 0,038 = 1,838 m
Not more complicated than that.
D Intermediate stiffeners and amounts
WALLS WITH OPENINGS (doors or windows)
E Cut out and assembly
1. To cut out all the amounts and to arrange them by categories
||2 To choose a plane ground to assemble
If your ground is tormented a little, to pose one or two panels of plywood . One can draw the element above and nail holds so that the amounts are adjusted in their place.
To position the amounts of the framework and to screw (or nail) the angles (snails of 70-80) . To maintain them well in their place in this operation.
To check that theoretical dimensions are well those of the outside of the framework and that there is no error.
To put the diagonal and to idem screw it then for the intermediaries.
For the walls, to screw with each angle a plywood square of 30 cm of side approximately after checking of the angles
or to brace by a board, these elements having to be removed later if the external coating ensures rigidity
if not to put amount interns wind-bracing on at least 2 panels of wall
For the walls with opening, to assemble the framework, to position the opening then to cut and to fix the consequently amounts: it is advised to take a larger thickness of amount or to double the amounts and to leave a little play (5 to 10 mm in height and width). And still: one can envisage a broad framework around the window to facilitate the water discharge outside (or to get it in the trade: base broad and typed insulation).
For the door, to envisage its site, the low amount of the framework will be cut out when the zome is fixed on the ground.
I do not advise to glaze roofing units difficulties question of sealing. If you want nevertheless, rather buy a commercial glazing of roof and low-size for the comfort of summer. Proceed for this rhombus as for these walls.
Thus make all these rhombuses and walls, check that their rigidity is satisfactory and store them.
