Definitions

  • the present invention relates to a method and apparatus for the modification of existing structures to provide improved resistance to extreme environmental conditions and, in particular, a system of common modular components for modifying existing buildings such as houses to provide improved resistance to extreme environmental conditions such as hurricanes, tornados, fires and so on.
  • nailed wooden structures are relatively light, strong and inexpensive and while the individual components comprising the structures, such as 2x4s and sheets of plywood, are individually relatively strong, their strength Is limited by the inherent properties of the materials. Wooden frame structures are also weakened, and tend to be excessively flexible, by the relatively large number of joints necessary to assemble the individual components. Also, nails are commonly used to assembly the individual components of wooden structures because nails are cheaper and easier to use than other forms of fasteners. Nails, however, do not provide joints that are as secure and rigid as those provided by more expensive forms of fasteners and nailed joints tend to flex or come apart relatively readily under various common forms of structural stress.
  • Masonry structures which are typically constructed from a combination of wooden structural elements, such as roofs and floors, and masonry elements such as bricks, blocks and slabs bound together and to the wooden elements by mortar or specialized fasteners, suffer from similar problems, as well as being heavier and more expensive to construct. While such structures may be initially stronger and more rigid than wooden structures, such structures often include even more joints than wooden structures, such as the joints between bricks and blocks, and mortar, for example, is very subject to cracking and sudden failure once a stress limit is reached.
  • masonry structures are susceptible to stresses that more flexible wooden structures will survive, such as stresses caused by earth movements, such as caused by earthquakes or by wave or landslide erosion, and masonry buildings, unlike wooden structures, will often fail catastrophically and almost completely once failure has started. It must be further noted that masonry structures of often subject to cracking with temperature induced expansion and contraction, as well as settling, and often present ventilation problems, resulting in excess humidity, condensation and possible mold growth.
  • Structures such as houses, schools, stores, governmental, public service and medical facilities and similar structures have also been constructed from modular iron or steel elements fastened together, for example, with metal pins or bolts or by welding. While this type of structure is generally stronger and more rigid in both the elements and joints than wooden or masonry structures, the significantly greater cost and weight of the structures and the fact that such structures are significantly more difficult, complex and time consuming to construct typically renders such structures impractical except in specific, special circumstances. Other implementations of such structures may use somewhat different materials, such as aluminum or plastic, but have all been found to suffer from one or more of the above discussed disadvantages.
