ABSTRACT:
BACKGROUND OF THE INVENTION
As urban growth occurs over time, a situation often arises where major arterial routes, especially freeways, become the hub of an infrastructure such that the immediately surrounding land is seen as best suited for developments such as high rise office towers, apartments, shopping centers and other commercial uses. Special zoning is often established for these “preferred development districts”.
Urban planners recognize that the land use in a preferred development district is typically a mix, including many business that have been at the same location for years and that don't require the new infrastructure. Such businesses will be referred to as “land-and-one-story businesses”, because their operation can typically be most economically conducted using land and one story buildings. Although at some point the business owners may realize the benefit from their land value appreciation, the overall land value appreciation in a preferred development district may actually do land-and-one-story business owners more harm than good, for the following reasons. First, it is often difficult to gain approval for improvements to property in a preferred development district. Because everything on a property will typically be leveled when a development project is undertaken, development authorities do not want to authorize nontransferable improvements because they will drive up the cost of property for developers, delaying preferred development. Second, land-and-one-story business owners are often faced with limited or no possibility of expansion at their current location, due both to the high cost of adjacent land, and due to restrictions placed on land use in preferred development districts.
If a land-and-one-story business decides to relocate, the business may find that their current property is of low overall market value, for the following reasons. First, the constraints described above will be faced by any new owner. Second, many people are reluctant to locate a business on property that may be absorbed into a large development project at any time. Third, because the properties of many land-and-one-story businesses have odd, irregular buildings, often built for a specialized purpose, often with a variety of aesthetic, code and regulatory problems, and often with a high percentage of open land, the total rental income such properties can generate is often relatively low, even if rental income per square foot for uses such as warehouse is relatively high. Because redevelopment may not occur for a decade or more, low rental value will significantly depress the market value of a land-and-one-story property.
PURPOSES OF THE INVENTION
One purpose of the building system of the present invention is to reduce the inherent conflict between urban planning authorities and land-and-one-story business owners, by comprising an integrated, modular system for building the basic structure of an inexpensive kind of temporary building that can significantly increase the rental value of land-and-one-story properties without adding significant unrecoverable costs that would delay preferred development.
A second purpose of the building system of the present invention is to comprise an integrated, modular system for building the basic structure of a building that is similar in appearance to conventional permanent concrete block and flat roof buildings, and that has fire resistance properties similar to permanent concrete buildings.
A third purpose of the building system of the present invention is to comprise an integrated, modular building system that can be built in cold climates without a significant unrecoverable investment in a deep foundation.
A fourth purpose of the building system of the present invention is to comprise an integrated, modular building system including engineering design components and architectural design components, for rendering specific buildings having a wide range of floor layout dimensions, such that a construction plan can be quickly prepared from modular elements for a specific building that will fit together with other buildings that are on a specific property, thus providing an increased square footage of rentable warehouse space.
A fifth purpose of the building system of the present invention is to comprise an integrated, modular building system for rendering specific temporary buildings such that if and when the buildings are later taken down, the same building can be erected elsewhere, or individual modules can be reused as parts of multiple other buildings of the present invention, or in other ways, so that most of the material cost of a building of the present invention is recovered if the building is taken down.
A sixth purpose of the building system of the present invention is to render buildings that, although temporary, can remain in service at a location for decades.
A seventh purpose of the building system of the present invention is to standardize a method of disassembling a building of the present invention, such that components are disassembled, staged, loaded and distributed efficiently from the disassembly site for reuse in the construction of other buildings of the present invention and/or for other uses.
SUMMARY OF THE INVENTION
The present invention comprises an integrated, modular system for designing, building, and disassembling the basic structure of an inexpensive kind of temporary building that is similar in appearance to conventional permanent concrete block and flat roof buildings, substantially fireproof, can be erected quickly, can remain in service on a site for decades, and that can then be disassembled such that most of the components can be reused at a different location in the same building, in other buildings of the present invention, or separately.
The wall components of the system of a building of the present invention are of two main block types. The first type comprises a variation of either industry standard sized 7⅝″×7⅝″×15⅝″ two cavity concrete block, or similar blocks with dimensions 7⅝″×7⅝″×18″. In addition to two cavities, each concrete block has one or more block assembly holes positioned such that when the blocks are stacked directly on top of one another without mortar, block assembly rods or block assembly columns, typically of steel and threaded at the top, are then run through the block assembly holes and into the foundation to form an assembly of stacked concrete blocks. The threaded sections at the top of the rods are used to secure roof modules. The second main type of wall block component comprises larger wall modules, typically of concrete, that can be hollow, or that can have an insulation core. These wall modules are also assembled using block assembly rods and/or block assembly columns that are free standing and that run the full height of the wall, through the inside of the wall modules and to the foundation. Such rods and/or columns can vertically support the weight of the roof independent of the wall block modules.
The wall components of the system of a building of the present invention include optional insulation panels that can be placed on either the inside or the outside of the building. These panels typically run the full height of the building, and comprise a layer of insulation board that is vapor sealed, an outer layer typically of finished veneer, and top and bottom flexible panel end sections. The bottom flexible panel end section is placed on the foundation and secured by the wall blocks that are placed subsequently. The top flexible panel end section is placed on the top of the wall blocks and is secured by the weight of the roof. The vapor sealed insulation board side interfaces with the wall blocks, and can be optionally spot glued to the wall blocks.
Wall components of the system of a building of the present invention are joined to roof components using plate modules placed at the top of the wall blocks. These plate modules include roof supporting sections of steel or a simila
