EG.3.30 4 4622 2046 8 3 v INI/ZNTOR. CHARLES H. Bz/vrusv BY H/S ATTORNEYS. HARE/.5, /(/CH, Russsu. & KERN DECK STRUCTURE AND CONNECTOR FOR DEMOUNTABLE PARKING BURDING, OR Tl-m LHGF.

BACKGROUND OF INVENTION The present invention relates in general to deck structures and, more particularly, to a deck structure especially suitable for use in a multideck demountable parking building, or the like.

Still more particularly, the invention contemplates a deck structure comprising beams providing rectangular bays, rectangular concrete slabs respectively covering the bays and having their edges seated on corresponding beams, and connectors spaced apart along the edges of the slabs and securing them to the corresponding beams.

' The invention still further contemplates a deck structure incorporating improvements on that disclosed in my US. Pat. No. 3,505,768, issued April 14, 1970.

SUMMARY AND OBJECTS OF INVENTION The primary object of the present invention is to provide a deck structure of the foregoing general nature including improved connectors spaced apart along the edges of the slabs.

An important object is to provide a connector comprising an angle member having a horizontal flange adjacent the bottom of the corresponding slab and having a vertical flange embedded in the corresponding slab and spaced inwardly from the corresponding edge thereof, thus more thoroughly integrating the angle member into the slab then in my prior patent.

Another object of the invention is to provide a vertical bushing extending upwardly from the horizontal flange adjacent the vertical flange and welded to the angle member and embedded in the corresponding slab, and a bolt extending through the bushing and the corresponding beam and having a nut threaded thereon. With this construction, there is no necessity for providing the bushing with internal threads which can become damaged, particularly if the structure is repeatedly assembled and dissassembled.

An object related to the foregoing one is to provide each slab with fittings spaced inwardly from the edges thereof for lifting the slab into and out of position. Such fittings not only eliminate any necessity for utilizing the edge connectors for lifting purposes, but they more uniformly distribute lifting stresses throughout the slab, and do not concentrate them adjacent the edges where they might cause cracking.

Another and important object of the invention is to provide a U-shaped anchor embracing the bushing of the connector and extending through the vertical flange of the angle member into the concrete of the corresponding slab.

Another object is to provide a construction of the foregoing nature wherein the U-shaped anchor is welded to the bushing and the vertical flange of the angle member to thoroughly integrate and rigidify the structure of the connector.

A further object is to provide a connector wherein the free ends of the anchor are enlarged to resist withdrawal of the arms of the anchor from the concrete of the slab.

Yet another object is to provide a construction wherein the upper end of the bushing and the top of the corresponding slab outwardly of the vertical flange are below the upper edge of the vertical flange to provide space for a nut or a bolt head.

A still further object is to provide a structure wherein the lower surface of the horizontal flange of the angle member is above the lower surface of the corresponding slab to provide space for a flange of the corresponding beam.

The foregoing objects, advantages, features and results of the present invention, together with various other objects, advantages, features and results thereof which will be evident to those skilled in the art to which the invention relates in the light of this disclosure, may be achieved with the exemplary embodiment of the invention illustrated in the accompanying drawing and described in detail hereinafter.

DESCRIPTION OF DRAWING In the drawing:

FIG. 1 is a fragmentary plan view of a deck structure of a demountable parking building, or the like, embodying the invention;

FIG. 2 is an enlarged fragmentary plan view duplicating a portion of FIG. 1 on a larger scale;

FIG. 3 is an enlarged fragmentary sectional view taken as indicated by the arrowed line 3-3 of FIG. 1 or the arrowed line 3-3 of FIG. 2;

FIG. 4 is a plan view of a slab connector of the invention; and

FIG. 5 is a fragmentary sectional view of an angle member forming part of the connector of the invention, prior to assembly of the angle member with other elements.

DESCRIPTION OF EXEMPLARY EMBODIMENT OF INVENTION In the drawing, the numeral 10 designates a fragment of a building structure, such as a demountable parking building, and, more particularly, designates a fragment of a deck structure for a building of this general character.

The deck structure 10 comprises longitudinal and transverse beams 12 and 14 providing rectangular bays 16. The beams 12 and 14 are shown as I-beams and are suitably interconnected with their upper flanges flush.

The respective rectangular bays 16 are covered by rectangular reinforced concrete slabs 18 having their respective edges seated on corresponding ones of the beams 12 and 14, as will be clear from FIGS. 1, 2 and 3 a of the drawing. As shown in FIG. 3, the joint between each pair of adjacent slabs 18 is sealed by an elastomeric seal strip 20 covered by suitable caulking 22.

Each concrete slab 18 is provided inwardly of the edges thereof with fittings 24 to which may be connected means, not shown, for lifting the slab into and out of position. As hereinbefore indicated, the use of such lifting fittings 24 spaced inwardly from the edges of the slabs 18 avoids stress concentrations at the edges which might cause cracking.

The respective edges of the concrete slabs 18 are secured to the corresponding ones of the beams 12 and 14 by connectors 30 spaced apart along such edges. The connectors 30 are all identical so that it is necessary to describe only one of them in detail.

Each connector 30 comprises a relatively short angle member 32 having a vertical flange 34 embedded in the corresponding slab 18 and spaced inwardly from the corresponding edge thereof, as best shown in FIG. 3 of the drawing. The upper edge of the vertical flange 34 is flush with the upper surface of the corresponding slab 18. Each angle member 32 also includes a horizontal flange 36 the outer edge of which is flush with the corresponding edge of the corresponding slab 18. The lower surface of the horizontal flange 36 is spaced upwardly from the lower surface of its slab 18 to provide space for the corresponding flange of the beam 12 or 14 on which the slab in question is seated.

Each connector 30 also includes a vertical bushing 38 extending upwardly from the horizontal flange 36 of the corresponding angle member 32 and disposed adjacent, but spaced from, the corresponding vertical flange 34. As best shown in FIG. 5, the upper surface of the horizontal flange 36 is provided with a flat portion 40 on which the lower end of the bushing 38 is seated. The bushing 38 is welded at its lower end to the horizontal flange 36.

The horizontal flange 36 of the angle member 32 of each connector 30 is provided with a hole 42 in register with the bushing 38. A bolt 44 extends upwardly through a hole in the flange of the corresponding beam 12 or 14, the hole 42 in the horizontal flange 36, and the bushing 38, such bolt having a nut 46 threaded onto its upper end in the particular construction illustrated. As will be apparent, the bolt 44 and nut 46 secure the connector 30 to the corresponding beam 12 or 14.

The upper end of the bushing 38 terminates below the level of the upper surface of the corresponding slab 18. Also, the concrete of the slab 18 is flush with the upper end of the bushing 38 in the area occupied by the angle member 32. With this construction, the upper end of the bolt 44 and the nut 46 are recessed below the upper surface of the corresponding concrete slab 18. This recess may also be filled in with suitable caulking 48, which may be the same as the caulking 22.

Each connector 30 also includes a U-shaped anchor 50 which embraces the corresponding bushing 38 and which has its arm 52 extending through holes 54 in the corresponding vertical flange 34 into the concrete of the corresponding slab 18. The anchor 50 is welded to the bushing 38 and to the vertical flange 34.

The free ends of the arms 52 are enlarged, as indicated at 56, to securely interconnect the slab l8 and the anchor 50. The enlarged ends 56 may take various forms. In the construction shown, the free ends of the arms 52 are simply split.

The foregoing construction provides connectors 30 which are securely connected to and integrated into the concrete of slabs 18. Thus, a strong and sturdy securing structure for the slabs 18 is provided.

Although an exemplary embodiment of the invention has been disclosed for purposes of illustration, it will be understood that various changes, modifications and substitutions may be incorporated in such embodiment without departing from the spirit of the invention as defined by the claims appearing hereinafter.
