Abstract
ABSTRACT OF THE DISCLOSURE
A cross-brace for connection to a pair of parallel conventional joists comprises elongate brace members assembled to form an X-shaped array, with a pair of vertical reinforcement members extending between outer ends of the brace members. The brace members and rein-forcement members are connected to one another and, when the cross-brace is assembled with the joists, the rein-forcement members abut mutually opposed sides of the joists. When I-beams are employed, the outer ends of the brace members and the opposite ends of the reinforcement members cooperate to form right-angled notches for snugly receiving longitudinal beam members, which are inter-connected in pairs by web members against which the rein-forcement members abut. The web members are connected by dovetail joints to the beam members instead of simply being inserted in a conventional manner into slots in the beam members.

Description
1 3250~ ~
7607-2 ;
.
The present invention relates to cross-braces for connection to a pair of parallel joists or beams, and to structural assemblies comprising joists or beams interconnected by cross-braces.
In a conventional building construction, floor joists are often provided with braces connecting the joists to resist lateral bending of the joists. Also, it is well known to form such braces as cross-braces, i.e.
braces comprising elongate brace members assembled to form an X-shaped array, these cross-braces being con-nected between the joists with the brace members extending at an inclination to opposed vertical side faces of the joists.
It i8 also well known to construct joists as I-beams, comprising an assembly of a pair of beam members interconnected by a web member having opposite longitudi-nal edge portions connected to opposed faces of the beam members.
'.
It is a disadvantage of conventional cross-braces that they provide lateral support for the joists only at the tops and the bottoms of the joists, i.e. at the locations at which the outer ends of the brace mem-bers abut the opposed vertical side faces of the joists.

The structure illustrated in Figures 1, 2 and 6 comprises a pair of conventional parallel joists indi-cated generally by reference numerals 10 and 11, which are of rectangular shape with opposed flat vertical side faces 12 and 14.
A pair of cross-braces, indicated generally by refer~nce numeral 16, extend between the side faces 12 and 14 for stiffening the joists 10 and 11.
~4~
Each of the cross-braces 16 comprises three elongate brace members 18, 19 and 20, which are connected together in an X-shaped array. The brace member 18 is longer than the brace members 19 and 20 and abuts, at opposite end faces thereof, against the surfaces 12 and 14 of the joists 10 and 11. the brace members 19 and 20, on the other hand, have their outer end faces in abutment with the joist surfaces 12 and 14, respectively, but have inner ends thereof in abutment with the brace member 18.
Vertical reinforcement members 22 and 24 extend between the free ends of the brace members 18, 19 and 20 and have outer side surfaces which are in alignment with the -:
brace member end faces to form therewith opposite flat lateral extremities of the cross braces and which abut the joist side surfaces 12 and 14. As can be seen from Figures 1 and 2, the thus formed la~eral extremities or side faces of the cross braces 16 extend ilush to the tops and bottoms of the cross braces 16 so as to allow the latter to fit between the joists 10 and 11 without projecting into or upwardly beyond the joists 10 and 11.
The brace members 18, 19 and 20 are connected to one another and to the vertical reinforcement members 22 and 24 by means of conventional truss plates 26 and 28.
As will be readily apparent from the above description and from Figures 1, 2 and 6, the cross-braces illustrated therein, as compared with conventional cross-braces lacking the reinforcement members 22 and 24, provide additional stiffening for the joists 10 and 11 and thus reinforce these joists against lateral deflection.
