Abstract
A floor system for a building that includes primary and secondary structural supports, a grid attached to the supports, and a plurality of panels removably mounted in the grid to provide access to the space below the panels and the grid. The floor system replaces conventional permanent structural floors, and provides ready access to the underlying space, which would otherwise be inaccessible in a conventional floor.
Claims23
A floor for a building having a plurality of primary structural building members lying in a first plane, comprising:
- a plurality of spaced-apart secondary structural building members spanning the primary building members and lying in a second plane that is substantially parallel to the first plane;
- a support grid spanning a distance between two of the plurality of secondary building members and bearing only on the two secondary building members, the support grid including intersecting structural members defining openings configured to receive panels, the distance spanned by the support grid exceeding a width or length of the openings;
- and
- a plurality of panels mounted on the support grid to form a section of a floor, each of the plurality of panels individually removable from the support grid to provide access to a space between the plurality of spaced-apart secondary structural building members.

A floor system, comprising:
- a prefabricated floor section, including:
- a plurality of support rails positioned a selected distance apart, each having a pair of spaced apart angle members with spacers positioned between the angle members, the plurality of support rails configured to extend between two horizontal structural members of a building, and
- a plurality of cross rails, each spanning between adjacent pairs of support rails, the support rails and cross rails together defining a plurality of apertures between adjacent pairs of support rails and adjacent pairs of cross rails;
- a plurality of connectors configured to be affixed to upper surfaces of the structural members of the building;
- each connector being further configured to be received between the pair of spaced apart angle members of at least one of the plurality of support rails, and wherein each of the plurality of support rails is configured to be affixed to respective pairs of connectors at selected heights above the respective structural members;
- and
- a plurality of removable floor panels, each positioned within one of the plurality of apertures.
4 more elements
A pre-assembled floor section, comprising:
- a plurality of support members positioned and rigidly coupled together to collectively define a plurality of openings sized to receive removable floor panels, the pre-assembled floor section configured to span between a plurality of horizontal building members;
- means for coupling the pre-assembled floor section to an adjoining pre-assembled floor section;
- a plurality of connectors coupled to respective ones of the plurality of support members for hanging a sub-floor deck below a level of the floor section, each connector having a threaded opening;
- and
- a plurality of threaded rods threadedly received in the threaded openings of respective ones of the plurality of connectors.

A floor for a building, comprising:
- a plurality of sections configured to be separately pre-assembled prior to a final assembly of the floor, each of the plurality of sections having a support grid defined by first and second pluralities of support members lying in a plane, the first plurality of support members lying parallel to a first axis and the second plurality of support members lying parallel to a second axis, perpendicular to the first axis, the support grid configured to receive a plurality of removable floor panels in respective openings of the grid, the support grid further configured to be coupled to adjoining support grids, and to span between first and second horizontal framing members separated by a distance greater than a length or width of any one of the plurality of floor panels;
- a plurality of fasteners, each coupled to a support grid of one of the plurality of sections;
- a plurality of hanging structures, each coupled to a respective one of the plurality of fasteners;
- a plurality of sub-floor deck support rails, each coupled to at least two of the plurality of hanging structures;
- and
- a sub-floor deck coupled to the plurality of sub-floor deck support rails.

A floor system for supporting removable floor panels between two secondary structural members of a building, comprising:
- a prefabricated floor section, including:
- a plurality of support rails positioned a selected distance apart, the support rails configured to extend between the two secondary structural members of the building, each of the plurality of support rails including a pair of spaced apart angle members with spacers positioned between the angle members,
- a plurality of cross rails, each spanning between adjacent pairs of support rails and rigidly affixed thereto, the support rails and cross rails together defining a plurality of apertures between adjacent pairs of support rails and adjacent pairs of cross rails, each aperture configured to receive a removable floor panel;
- and
- a plurality of fasteners, each configured to be affixed to one of the secondary structural members, each of the plurality of fasteners coupled to an end of a respective one of the plurality of support rails.
