Hurricane Damaged Shelter Recovery Method for British Virgin /Caribbean Islands / Usa with little or no budget

Hurricane Damaged Shelter Recovery Proposal Method for British Virgin /Caribbean Islands / Usa with little or no budget


Method 

1. Collect wood that is plentiful due to fallen trees / joists / stick frames 

2. Sort or cut wood into 50mm /70 / 140mm thick planks

3. paints planks with preservative 

4. Clad & nail / screw planks inside galvanised drywall lining channel or purlins, salvaged from destroyed buildings 

5.Drill holes in structurally sound brick walls, insert plastic walls plugs , glued in with injection resin or adhesives

6. Screw metal clad  planks to wall, horizontally & vertically , so a 2.4 x1.2m sheet can be screwed to it    

7  Fill insulation voids with plastic bottles filled with polystyrene or bubble wrap (or sand / soil / water if thermal mass / heavier wall weight required) .

8. Tape these bottles together with very strong fibre reinforced tape to add strength . while retaining insulation & flexibility

9. Screw sheets of MGO (Magnesium Oxide) fire board / corrugated grp / metal sheeting (or what wood sheet is available )   to the outside. 

A related Cabinz Idea for Reinforcing Window Storm Plywood Shutters on a Budget with Cut Up Used Tyres 
may be of use for shutters / doors & tying down roofs

10. Battens composed of strips of plastic or treated wood could be added to outside of MGo board or corrugated grp / steel , before boards are screwed in place.

11. If a stand alone structure is required, a hexayurt like our prototype can be built using a method similar to the above.

The truth about recycling


We take it for granted that recycling is the best way to dispose of waste. But is that just greenwash? New Scientist sorts through the trash so that you can make up your mind
Which materials are worth recycling?

From the most basic environmental point of view, all materials are worth recycling, because this reduces the need for energy-intensive mining and smelting of virgin materials.
That makes a huge difference for some things – notably aluminium – but even recycling glass leads to a small energy saving and consequent reduction in greenhouse gas emissions.
Recycling can also provide a reliable, non-imported source of scarce resources such as the rare earth metals that are crucial parts of touchscreens and other high-tech devices.
However, the answer gets muddier when we consider economics. The price of recycled material fluctuates wildly, and some often aren’t profitable to recycle, especially if the recovered material has to be shipped long distances to a reprocessing plant.
Waste managers often have to pay recyclers to take glass off their hands, for example. That can make virgin glass look like a better deal – but only because we often fail to include the environmental costs of mining sand and the carbon emissions from glassmaking furnaces.
Similarly, plastics are often reprocessed in China, so proximity to a seaport may dictate whether it is profitable to recycle them.

Other low-value materials such as wood and textiles need to be clean to be recyclable.
The extra effort and expense required to separate them from general waste means they often end up in landfill.
 Wasted opportunities
Can we make landfill greener?
 

Landfill sites emit methane, a potent greenhouse gas. A growing number capture this and convert it to energy but even in the most efficient...

Idea for Reinforcing Window Storm Plywood Shutters on a Budget with Cut Up Used Tyres


 Used Tyres, locally available for free, can be easily cut up with a hand blade & a metal jig saw blade (for side wall metal tyre bead) to strengthen a plywood or metal shutter.

The tyre off cuts are screwed and / glued into raw plugs in the wall . Preferably bolted to the plywood

If there's no money for plywood , salvaged pallets could be used 





For bigger windows the tyre tread can be cut

 A Variation.


The whole shutter counld be covered with over lapping tyre treads fo max strength, but weight would be heavy.

First ideas for total coverage layout






Perhaps a combination of the side walls & tread would work best . Side walls could be cut as complete circles & screwed to tread strips

Using Old Car Tyre Strips to Join Stick Frame Hexayurt Panels to Form a More Flexible Joint

 While currently building the Hexayurt with Drywall / Composite Stick Frame & Magnesium Oxide ( Mgo) Board Cladding . Re-used Insulation Infill 

I was thinking about variations on joining of the panels.

As I am re-using free bottles etc for the insulation, and given the current hurricane in Florida, I was thinking of a free & plentiful, strong flexible seam that would withstand a high wind. 

Old worn tyres came to mind.

Note. if the edge sealant does not waterproof the seam, a covering flashing (perhaps of grp sheet strips may need to be installed) ) 

After trying another method (see following pics) I think its best to:

  ( Update ) Related shelter 

 Maison Gomme is a quirky backyard shed made with recycled tires

1.  cut both sides off as per the vid below with a Contour Knife & Trimming Blade .

 

2. Then cut the tread part of the tire one with a metal bladed jig saw. This leaves a flat strip .

3. Put a bead of silicon sealant along the side of tyre or panel edge

4. screw (tyre wall screws well into metal dryall clad wood etc) or ideally bolt (stronger) each side of the tyre strip to the panel.

5. A grp tape reinforced 70mm diameter plastic bottle tube couble be placed inside the stip to act as an air filled support

 Other method I tried, if a wider strip is required ( a notorcycle tyre could also be used )

 Note: tyre does not need to be cut in half , just do one cut .

Then side wall is cut on bothe sides to allwo tyre to be spalyed out flat


Close up 
Drill tyre with metal or wood drill bit 

 Tyre wall screws well to panel

A strip of taped , air filled 70mm dia bottles  can be used as a filler

 close up in situ

Note 6mm Mgo Board bends quite a lot without breaking, (pic), so I will be making a prototype curved panel,  which wll perhaps remove the need to have a wedge shaped tre strip installed.

However a curved frame may be more labour intensive

Draft proposal for Design of Insulated Panels installed as Shelter Wall Insulation, that can be Re-used as Shelters in the event of a Disaster Situation


Paul Ridley, Founder of the Cabinz Project Uk has designed several insulated panels that can be attached to an existing brick or wood building to insulate it, and make the structure stronger. 

These are designed to counter the problem that if a disaster occurs, there will not be enough materials available immediately to build thousands of shelters.
By have the panels dispersed around the country, in use as insulating building panels , they can quickly be removed from buildings & re-used as emergency shelters or perhaps floating pontoons in a flood.

While the panels are in situ, this addresses the problems stated in the 2 articles below  


If there is a disaster, where thousands of shelters are needed very quickly, the panels can be removed and built into shelters such as Hexayurts


The panels are screwed onto a metal drywall / wood or plastic strip that is connected via wall plugs to the wall. 

The panel has a metal drywall frame, and magnesium oxide (MGO fire ) board on the outside, painted with masonary paint .


There are a variety of insulation core options to suit differing budgets and levels of fire resistance.

Inflammable insulation should ideally be encased both sides with fire resistant Mgo board & metal drywall frame. Fire resistant materials require only single external mgo board sheet cladding.

Note:  Fire resistant materials such as PIR can be further removed from the frame and made into Hexayurts etc, as well as the outer 2.4 x 1.2m framed panel, so nearly doubling the panel usage (inner panel will be slightly smallet to fit inside framed one)   

Some meet building regs, others do not : 

A. Fire Resistant

1. Pir Rigid foam ie Kingspan as seen here in off cut form.  

2. Mineral Wool

3. Off cuts from Industry 


B. Inflammable 

End sealed cardboard (this is currently under study , and may be rejected if damp issues occur) 

 2. Approx. 70mm diameter bottles, cans & cartons filled with bubble wrap or polystyrene off cuts
(Edit 20-4-18) Idea is that bottles voids could be filled with co2 gas to make them more fire resistant & act as co2 capture devices )

3. Inflammable off cuts from Indusrty
