Rosecrans Avenue, Saute Fe Springs, California HOLLOW CONCRETE FLOOR PANEL FOR SINGLE AND MULTI-STORY CONSTRUCTION Warm Air Radiant Heating and Ventilating or Complete Air Conditioning ' for Schools, Churches, Residences, Hospitals. Industrial Buildings Airfloor forms create a strong, hollow floor serving as a common plenum for conditioned air, radiant heat, and positive mechanical ventilation for complete air-conditioning systems. Airfloor introduces all air passing through the floor into the occupied space. For use with Gas, Oil, Electric, or Coal Fired Furnaces, fan-coil units, multi-zone units, etc. t sumr W M. or Sq.

A flat slab construction, which may be poured in place or lifted in place allowing flexibility of partition locations. 6. A plenum or duct through which conditioned air passes thus providing a radiant panel and simultaneous convection heating or cooling. 3. A railing already in place. 4. A reduced load of 35 pounds per square foot which in turn reduces concrete weight, supporting column, beam and foundation sizes. 5. A considerable reduction in seismic forces due to floor dead loads. 7. More utilizable volume in multi-story buildings, by elimi nating required space for exposed ductwork at each floor level. This is especially important where limit-height build- * ings are concerned 8. The ease of installation of hidden piping and electrical work. The necessity for rigid electric conduit is eliminated. 6. Flexibility in partition locations. AIRFLOOR FORM SPECIFICATIONS STANDARD MATERIAL: 26 gauge cold rolled steel -fgalvanized steel forms optional at extra cost). STANDARD WEIGHT: One pound per sq ft. SIZE: 12 in. x 12 in. x 3Va in. CONCRETE DISPLACEMENT: The concrete displaced by one Airfloor form is 0223 cu ft. COMPRESSION LOAD TEST: By California Testing Labo ratories, Inc, on June 8,1955, Lab No. 42288: Compression load was applied to a six inch diameter (0.196 square foot) disc which centered over the one inch thickness of concrete at the center of the form. The following tabulation gives the results of this test: COMPRESSION LOAD IN POUNDS: 9,250. RESULT: No cracks appeared until failure which fractured the concrete by punching shear at the edge of the disc. FIELD CONDITIONS: Linear gain over installed Airfloor forms: 2 ft 0 in. AIRFLOOR REGISTER SPECI FICATIONS Material: 20 gage cold rolled steel. Length: 48 in. standard or cut to suit architectural requirements. Height: 6J*-, Backplate & Dampers: Optional.
