' A. JORDAHL CONCRETE INSERT Fi'l'ed Nov. 2, 1925 Amie/1r z/rdahl Patented July 21,
ANDERS- JORDAHL, OF NE! YORK, Y." i
CONCRETE mam;
Application iiltl Navember a, 1923. serial (72,392.
T all whom it may] concern Be it known that I, Animus JORDAHL, subject of the T ling of Norway, residing at New York, in the county and State of New York, have invented certain new and useful Improvements in Concrete Inserts, of which the following is a specification.
The present invention relates to a steel insert adapted to be embedded in concrete work for the purpose of providing an anchorage for various kinds of equipment such as overhead shafting, electric cables, pipes, lighting fixtures, etc. The insert can be suitably made by first rolling a steel plate into the desired channel rail and then by punching out the slots and shearing the flanges to provide the rail with anchorage stirrups. The object of this invention is to provide a safe and rigid anchorage for overhead equipment which can be easily adjusted or removed and which by means of the bolts provides a quick installation for the equipment. Another feature of the invention comprises a cover plate to be placed over and along the opening of the channel rail in order to prevent the concrete from entering the rail during the building operation and also to act as a horizontal bracer and spacer thus providing further means for securing a rigid insert.
The advantages derived from the present invention are their safe carrying capacity, strength, dependability and adjustability of the equipment carried.
The invention will be more readily understood from the following description and the drawing in which like reference characters indicate corresponding parts throughout and in which lligure 1 is a sectional view of the insert embedded in concrete, showing parts of the concrete broken away to show the stirrups,
Fig. 2 is a side view thereof, having portions broken away, and
Fig. 3 is a bottom view of the insert.
The insert comprises a channel rail 1 having side portions 11 and flanges 9 which is adapted to be embedded in concrete as shown, the numeral 2 indicating the concrete work such as a beam or ceiling. The flanges are sheared at suitable intervals to provide stirrups 3 having bent upper ends 4 in order to insure a firm anchorage in the concrete. The channel rail 1 is provided on its bottom or bridge portion 1.0 with slots 5 which are punched therein for the purpose of receiving a securing means such as a bolt 6 which is adapted to project through the slot. The bolt has a head 16 which rests on the bottom portion and it will be seen that it can be moved the distance of the slotor moved from one slot into another slot by sliding the bolt in the channel in a horizontal position. In order to insert the bolt into the insert one of the slots 5, which is preferably an end slot indicated by the numeral 17, is provided with an opening 7 adjacent the end of the slot. This opening 7 is made large enough, and is shaped, to receive the head 16 of bolt 6. In order to prevent the bolt from sliding over and falling throughi the opening 7 bolt stops 8 are bent up on each side of slot 17 adjacent to opening 7 and it will thus be seen that the head of the bolt can be moved to abut against stops 8 but must be lifted over these stops in order to remove it from the insert.
The insert can ofcourse be embedded in the concrete to any desired depth but for the purpose of securing as rigid a mounting as possible and attaining the greatest strength for the concrete, it is preferably embedded so that the outer surface of the bottom portion 10 is flush with the outer surface of the concrete work 2.
In order to prevent the concrete from entering the channel rail during installation and to provide a bracing and spacing memher, a cover plate 12 of any suitable material but preferably of sheet steel is forced down. between the stirrups 3, on inner edges of the flanges 9. This plate is bent at right angles at each end as shown at 13 in order to form an end stop and also a portion 14 bent at right angles to the end stop as shown. The insert may be installed by placing channel rail 1 on the scaffolding either before or after the cover plate has been inserted. By means of the bent portion 14 of the cover plate the insert can be properly secured in place on the scaffolding'and thus cannot be shifted out of place during the pouring of the concrete. Furthermore as the concrete, is poured the side portions have a tendency to be forced inwardly which is prevented by the cover plate. It will thus be seen that this plate performs many important functions both during and after installation.
I claim as my invention:
1. A concrete insert comprising a channel rail having slots in the bottom portion 10 adapted to receive securing means; a stop on each side of one of said slots to form an abutment for said securing means; flanges on said channel rail and having stirrups thereon; and a cover plate for said rail on said flange and between said stirrups.
In testimony whereof I aflix my signature.
ANDERS JORDAHL.
