STRUCTURAL REEN'EOBCE ELEMENT.

Application filed October 22, 1826. Serial No. 143,479.

enforce bars for use in columns and the like.

Objects pertaining to details and economies of my invention will definitely appear from the detailed description to follow. The invention is clearly defined and pointed out in the claims.

A structure embodyin the features of invention is clearly illu if: c c panying drawing forming a plication, in which Fig. l is a fragmentary perspective view of my improved reenforcing element, a section of form being shown in operative relation thereto.

Fig. 2 is a horizontal section through the complete reenforcing element on line corre sponding to line 2-2 of Fig. 1.

3 is a perspective view of one of my improved reenforce bar spacer units or tie units.

Fig. t is a fragmentary section sho ving the n'ianner of connecting the longitudinal rods to the cross members.

Referring to the drawing, 1 represents the ire enforcing bar and 2 a form for column or the like. Each structural element com- L es a plurality of the reenforce-bars 1, much are spaced and tied together by my improved fo e bar spacer or tie units, each cons o' a plurality of cross memors 3 formed of light rod or heavy wire of suitable gage. These, when the column is to be of rectangular cross section, are bent to an angular form, the arms 4: of the cross members terminating in inwardly turned ends or lugs 5, thus providing a cross member with an open side and three inwardly facing angles.

llhese cross members are secured together in spaced parallel relation by means of the longitudinal rods 6 which are welded to the arms of the cross members as shown in Fig. l, thereby supporting the cross members in a fixed spaced re ation. The spacer units are employed in coaeting pairs with their ends overlapping as shown in Fig. 2, the ends engaging corresponding diagonally opposite so that the longitudinal bars themselves constitute locking members.

in the embodiment illustrated there are ten reenforcing bars, four disposed in the angles of the spacer units and the others distributed in intern'iediate positions.

The bars are secured to the spacer members by means of the ties 7, wire ties being found very satisfactory for this purpose.

r thus forming the parts the structural elements can be rapidly assembled on the job, the bars being laid into one of the spacer units of-a coacting pair through the open sides thereof, the other spacer unit positioned and the bars tied in place, this forming a complete or unitary structural element which may be handled as such. Or, if desired, the reenforee bars may he stood upright and the spacer units slipped about the same.

When assembled the parts are very. effectively held in position. The spacers are economical to produce and very convenient to use.

Having thus described my invention what I claim as new and desire to secure by Letters Patent is:

1. A reenforce bar spacer unit consisting of a plurality of spaced angular cross members, the arms of which are disposed substantially at right angles to each other and terminate in inwardly turned ends to provide three inwardly facing angles in which reenforce bars may be disposed, and longitudi nal rods fixedly secured to the arms of said cross members whereby they are supported in a fixed spaced non-collapsible relation.

2. A reenforce bar spacer unit consisting of a plurality of cross members open at one side and conformed to provide three inwardl facing angles, and longitudinal rods to which said cross members are connected in spaced non-collapsible relation.

3. A reenforce bar spacer unit comprising a plurality of spaced cross members open at one side, the ends of which terminate in inwardly turned lugs, and longitudinal rods fixedly secured to said cross members whereby they are supported in a fixed spaced non-collapsible relation.

4:. A structural element comprising a plurality of reenforee bars, spacer units disposed in opposed coacting pairs, each comprising a plurality of spaced angular cross members the arms of which are disposed substantially at right angles and terminate in inwardly turned ends providing three inwardly facing angles in which reentorce bars are disposed, the ends of the arms of said cross members being disposed about diagonally opposite bars and in overlapping relation, longitudinal rods fixedly secured to the arms of said cross members whereby they are supported in fixed spaced relation.

5. A structural element comprising a plurality of reent'orcing bars and spacer units disposed in coacting pairs, each comprising a plurality of spaced cross members open at one side, the ends of which terminate in inwardly turned reent'orce bar engaging lugs, longitudinal rods to which said cross 1nembers are connected in spaced relation, the spacer units being disposed in opposed relation with their inwardly turned lugs engaging correspondin reentorcing bars, and ties securing said reenrorce bars to certain of said cross members.

6. A structural element comin'ising a plurality of reenforcing bars and spacer units disposed in coacting pairs, each comprising a plurality of spaced cross members open at one side, the ends of which terminate in inwardly turned reen'force bar engaging lugs, longitudinal rods to which said cross mei'nbers are connected in spaced relation, the spacer units being disposed in opposed relation with their inwardly turned lugs engaging corresponding reenforcing bars.

7. A structural element comprising a plurality of reentorce bars, and enacting p airs of angular cross members disposed in opposed facing relation, the arms of said cross members being disposed substantially at right angles to each other and terminating in inwardly turned ends providing each cross member with three inwardly facing angles, the ends of the arms of the coacting pair of cross members being disposed about diagonally opposite reenforce bars in overlapping relation, and ties securing the said reenttorce bars to said cross members.

8. A structural element comprising a plurality of reentorce bars, and coacting pairs of angular cross members disposed in opposed t'acing relation, the arms of said cross members being disposed substantially at right angles to each other and terminating in inwardly turned ends providing each cross member with three inwardly facing angles,

the ends of the arms of the coacting palr of F cross members being disposed about diagonally opposite reenforce bars in overlapping relation.

9. A structural element comprising a plurality of reentorce bars, cross members disposed in coacting pairs to embrace said reenforce bars, said cross members being open at one side and terminating in inwardly projecting lugs disposed in engagement with a pair of longitudinal bars constituting tie members connecting the pair of cross members.

In witness whereof I have hereunto set my hand.
