THE “UNIT” SYSTEM OF REINFORCED CONCRETE
UNIT GIRDER FRAME READY FOR INSPECTION
POINTS POSSESSED BY THE “UNIT” GIRDER FRAME
Patented
FOR CONCRETE REINFORCEMENT
There is no other “ Girder Frame ” made and delivered as a “Unit”
It is the best Reinforcement for Concrete Girders, Beams, Lintels, etc., because
1. Designed as a “Unit. ” 2. Built as a “Unit. ”
3. Delivered as a “Unit. ”
4. Supported as a “Unit. ” 5. Erected as a “Unit. ” 6. Acts as a “Unit. ”
7. It is carefully designed for each span. 8. Each member is the necessary size. 9. It is the proper shape.
10. Tension and shear members scientifically spaced. 11. All parts securely held.
12. No part can be forgotten. 13. Nor omitted.
14. Entire Frame is placed at once.
15. Only system in which the concrete can be thoroughly tamped without disturbing the reinforcing members.
16. Adapted for use with every conceivable system
of slab reinforcement.
17. Slab reinforcement laced through stirrups. 18. Therefore making a complete T section.
REPLACES THE STEEL BEAM WITH ABSOLUTE SAFETY
UNIT GIRDER FRAME PLACED AS A UNIT
“UNIT” SOCKET FOR CONCRETE REINFORCEMENT
Patented
IS DESIGNED
First: To locate the center of action of the steel reinforcement before a particle of concrete is put into the mold. Avoiding all guesswork. Second: To allow careful inspection of the reinforcement before concreting.
Third: To make sure the exact amount of concrete for fire-proofing is there.
Fourth: To prevent the reinforcement from being moved to the right or left or up or down while tamping the concrete.
Fifth: To save time in erection. No wiring or banding or blocking of reinforcement required.
Sixth: That when the beam is finished and the cen
tering removed, it can be used to support suspended ceilings, partitions, shafting, steam pipes, gas or electric fixtures, fans or motors, without the use of expansion bolts.
Seventh: To avoid the injury to a beam, often caused by drilling when using expansion bolts.
Eighth: Each socket will support any load carried by a ¾-inch bolt.
Ninth: Can be placed as close as desired without injury to the beam.
It is the first and only attempt to locate the reinforcing
metal in a positive manner.
IF YOU DESIRE A FIREPROOF FACTORY BUILDING OR A WAREHOUSE
You can build the floors of reinforced concrete at 20 per cent. to 25 per cent. less than steel fireproofed
with terra-cotta, and the rate of insurance will be the same.
You understand the floor layout and beam spacing will be identical with your present plan. To obtain this saving use the “Unit” Girder Frame, “Unit” Socket and local labor.
