Park Lodge Elementary School in Lakewood, Washington.

The play shelter has the classic delta frame silhouette: A central A-frame section with a rise of 20 feet from concrete piers and a clear span of 40 feet, and two 2O-foot flat wing beams cantilevered from the legs of the A-frame. Four of the bents spaced on 16-fooi centers form the skeleton of the 82x56-foot structure.

_.Two experimental products were used in the prototype. These are .factory-prefinished panels which Weyerhaeuser !_omp_any produced by bonding duPont's synthetic rubber Hypalon to .fir plywood sheets; and Hypalon tape, a pressure-sensitive, waterproof tape produced by Minnesota Mining and Manufacturing Company from strips of Hypa- lon 8 to 10 mils thick. Neither the Hypalon tipe nor the Hypalon-overlaid plvwood is commeriially available at this time.

A proprietary .item, the delta frame is being marketed through Plywood Fabricator Service. W. D. Pige, executive vice president of PFS reports that 28 licens& fabricators thro-ugho_ut the c.ountry are prepared to supply any of the standard 608 versions of the basit component-atrywhe.e in the continental United States.

With these 608 variations it is possible to produce an entire family of buildings ranging -from superirarkets, to restaurants, to churches, to shopping centers, to industrial plants.

All variations of the component have the central A-frame section with its 20 loot rise and 40 foot span. The height of the_ridge- is variable with the height of the concrete p-iers.

.Wi"g. b-eams car! be cantileverEd from one, or boti legs of the A-frame up to 28 feet in 4-foot increments so thit the widest bent in the cantileverd series is 96 feet.

When supported by a post, the wing beam can be tended to 4O feet, with an additional 6-foot overhang, an overall bent width of 132 feet.

. Using standard design information produced by DFpA, bents can be spaced on 12,16,20 or-24 foot..tt"..

"r.,i there is no limit to the number of bents that can be aligned in series.

Among the 608 variations of the component are desisns for live roof loads ol I0,20,30 or 40 pounds per square fJot. (Allowance is made for a l0 poutrd per square joot dead load as well as a 20 pound per square foot wind load.)

Standald. designs 99 ""-t call for specific roofing or'wall systems. Since the delta frame skeleton is structirally independent, non-loadbearing (curtain) walls can be p.orrid"d conventionaliy.

1"y conventional roofing system-including stressed skin panels, folded plates, vaulls or standard j"oists with plywood decking-is possible in combination with the delta rrames.

_

4ll.""g the _ advantages of the system, according to DFPA, are reduced on-iite labor reqtiirements, quick Erec- tion oJ large buildings, a way to achieve versatile, engi- neered structures economicall)' competitive with less'imalinative "low-cost" buildings. The delta frame has inhere"nt benefits of both the A-frame section with reasonable clear span and Sjiling clearance and the low-roofed wings with ethclent ottrce or storage space.

DFPA Architect Robert B. Waring, who deprototype structure, said that half-bents could from one point to produce a circular or trianarea. Such bent arrangements, however, are for in the standard 608 variations available
