Multiuse construction system: multispace 2000

A modular building system for a building, including a visible foundation comprising structural beam elements of reinforced concrete having a plurality of foundation rods extending upwardly therefrom, a plurality of modular blocks for forming walls of said building extending upwardly from said foundation beam elements, said blocks having vertical apertures therethrough and adapted to be assembled into said walls such that a plurality of vertical ducts are formed in said walls by the apertures of adjacently assembled blocks, wall rods having upper and lower ends, the lower ends of said wall rods being connectable to said foundation beam rods at selected locations thereof and adapted to extend upwardly through selected ones of said assembled wall ducts, at least some of the wall rods being of a height where the upper ends are exposed above, an assembled wall, modular floor beams and means for connection of said floor beams to said visible foundation beam elements, and modular first ceiling beams for extending between side walls of the building, said ceiling beams adapted for support and connection to said walls in association with the exposed upper ends of said at least some of said wall rods, and a roof structure formed of modular beams for connection with said walls in association with the exposed upper ends of said at least some of said wall rods, characterized wherein means demountably connects said roof structure to said walls whereby said roof structure is removable from an assembled building whereby said walls may be extended upwardly by additional said modular block to form a second level, said first ceiling beams forming support for modular flooring of said second level, and said roof structure can be mounted on said extended walls, and further comprising modular wall corner blocks, modular flooring, windows, doors to complete and enclose said building according to a predetermined design, and further characterized wherein said modular wall blocks have top and bottom surfaces, opposed inner and outer sides and opposite ends, said top and bottom surfaces having complementary recess and protrusion configurations for interfitting vertically adjacent blocks, and wherein said modular wall blocks each have a channel in each of the top and bottom surfaces, each said channel being inwardly adjacent said outer side whereby when blocks are assembled to form a wall, said channels of adjacent blocks form a conduit for containing means to seal said walls from elements of weather.

In a method of constructing a building which can be expanded upwardly as desired, the steps comprising:

• providing a plurality of visible foundation beams to form a foundation for the building, said foundation beams including foundation rods extending upwardly therefrom at selected locations;
• providing a plurality of modular wall blocks for assembly on said foundation beams in a selected configuration to form walls of said building, said modular blocks each comprising a channel in each of top and bottom surfaces thereof, said tot) and bottom channel being inwardly adjacent an outer side of each of said modular blocks, said top and bottom channel forming a conduit for containing a sealing means for sealing a wall formed from said plurality of blocks from the elements, certain of said modular wall blocks being formed such that window and door apertures can be defined as desired, said modular wall blocks having vertically oriented apertures therethrough and assembled such as to define vertical ducts in an assembled wall;
• providing a plurality of wall rods and connection means for connecting said wall rods to said foundation rods, said wall rods extending upwardly through selected ones of said wall ducts, at least some of said wall rods having upper ends exposed above an assembled wall;
• providing ceiling beam holder boxes having means for connection with said exposed upper wall rod ends, of opposed side walls of said building;
• providing ceiling beams for cooperation with said ceiling beam holder boxes and means to connect said ceiling beams to said beam holder boxes;
• and,
• providing a demountable roof structure for connection to assembled building walls, through connector means and said exposed upper wall rod ends, whereby said building can be upwardly expanded by removing said roof structure and extending said wall rods and walls upwardly to define a second story on which said roof is again detachably mounted.
