Abstract

A demountable building usable as a garage with a large number of parking stalls. Precast reinforced concrete vertical frame units each have a width equal to that of a parking stall, and a height equal to the full height of the building at its location. Each frame unit comprises a pair of parallel columns and a series of horizontal beams interconnecting them, and each floor level has a projecting supporting ledge on each column. Each line of frame units has the columns all co-planar, and the frame units are spaced from each other by approximately their own width. Each end of a series of prestressed concrete channels rests side by side on the ledges. The slabs are each the width of a stall and have a pair of depending flanges along each side, these flanges resting on the ledge, and the channel spanning between two series of frame units. The slabs are bolted together and to the frame units to provide the necessary rigidity and to enable demounting.

Claims

1. A demountable building including in combination:

a plurality of series of precast reinforced concrete vertical frame units, each said frame unit comprising a pair of parallel columns and a series of horizontal beams interconnecting said columns, each said column having at each floor level a projecting supporting ledge, all the columns of each said series of vertical frame units being co-planar, the frame units of one said series being parallel to the frame units of other said series, the frame units of each said series being spaced from each other by approximately the width of a said frame unit, a series of prestressed concrete channels side by side each having a long top flat slab and a pair of depending flanges along each side, each said flange resting at each end on a said ledge, each said channel spanning between two series of said frame units, adjacent channels having their flanges closely adjacent each other, a first series of demountable fasteners, each extending through two closely adjacent flanges of adjacent channels and securing them together, and a second series of demountable fasteners rigidly securing said channels at each end to said columns.

2. The demountable building of claim 1 wherein each of said second series of demountable fasteners secures two said channels to each said column.

3. The demountable building of claim 2 wherein said flanges of said slabs have through transverse openings adjacent to and spaced from their ends to enable installation of and tightening of said second series of demountable fasteners.

4. The demountable building of claim 3 wherein each said flange has a slot along an outer face thereof from said transverse opening and each said demountable fastener for that location has bearing means for bearing against the wall provided by said transverse opening.

5. A demountable garage building having a large number of parking stalls, including in combination:

a plurality of series of precast reinforced concrete vertical frame units, each said frame unit having a width equal to that of a said parking stall and a height equal to the full height of the building at the location of that frame unit, each said frame unit comprising a pair of parallel columns and a series of horizontal beams interconnecting said columns, each said column having at each floor level a projecting supporting ledge, each said series of frame units being placed in a vertical plane with its columns all co-planar, the frame units of each said series being spaced from each other by approximately the width of a said stall, a series of prestressed concrete channels side by side each having a loNg top flat slab the width of a said stall and a pair of depending flanges along each side, each said flange resting at each end on a said ledge, each said channel spanning between two series of said frame units, adjacent channels having their flanges closely adjacent each other, a first series of bolts extending through the closely adjacent flanges of two adjacent channels, and the next, to them by nuts to prevent relative motion between channels when car wheels move from one said slab to the next and a second series of bolts, nuts and bearing plates rigidly securing said channels at each end to said columns.

6. The demountable garage building of claim 5 wherein each of said second series of bolts, nuts and bearing plates secures two said channels to each said column.

7. The demountable building of claim 6 wherein said flanges of said slabs have through transverse openings adjacent to and spaced from their ends to enable installation of the bolts, nuts and bearing plates there and to provide transverse wall surfaces for said bearing plates to bear against.

8. A demountable garage building having a large number of parking stalls on a plurality of floors, including in combination:

a plurality of series of precast reinforced concrete vertical frame units, each said frame unit having a width equal to that of a said parking stall and a height equal to the full height of the building at the location of that frame unit, each said frame unit comprising a pair of parallel columns and a series of horizontal beams interconnecting said columns, each said column having at each floor level a projecting supporting ledge and, therefore, a through opening, each said series of frame units being placed in a vertical plane with its columns all co-planar, the frame units of each said series being spaced from each other by approximately the width of a said stall, a series of prestressed concrete channels side by side, each having a long top flat slab the width of a said stall and a pair of depending flanges along each side, each said flange resting at each end on a said ledge, each said channel spanning between two series of said frame units, adjacent channels having their flanges closely adjacent each other, each said flange having a plurality of bolt openings matching such openings in other flanges, and each said flange having adjacent each end an access opening and having a slot along an edge wall extending from said access opening to the end of said channel, a first series of bolts extending through the matching bolt openings of the closely adjacent flanges of two such adjacent channels, and secured to them by nuts, to prevent relative motion between channels when car wheels move from one said slab to the next, and a second series of bolts, bearing plates, and nuts rigidly securing two said channels at each end to each said column, some of said bearing plates bearing against a wall of said access openings of two adjacent said flanges, said bolts extending through said slots.

9. The demountable garage building of claim 8 wherein some of said frame units lie between two sets of said channels, said bolts of said second series there extending not only through said columns but also from the access openings of one pair of said channels on one side of said columns to the access openings of a second pair of said channels on the opposite side of said columns.
