METHOD OF ATTACHMENT of panels at the eaves (left) and atop a glue laminated arch (right) is shown in these drawings provided through the courtesy of Unit Structures, lnc., and the Unicon Company, which latter

organization holds the patents on the lockstrip method indicated. Even a brief study of these drawings reveals

the very simplicity-and the secret of the strength-of the construction Max Hanish has popularized so much.

is not affected by heat and will fail only slowly after its solid cross section has been materially reduced by direct exposare to fire, which is further slowed down once a wood member is charred. From these technical characteristics alone, theatre management can see an advantage in their field.


The above, briefly, are the engineering features involved; and, while they are basic, perhaps their application to specific theatre construction might be more apparent from Mr. Teichertls point of view of what they can do toward a decorative theatre interior. When asked about this, Mr. Teichert said that, aside from providing this aforementioned strong, economical and safe construction, these sections of laminated wood could, after erection, be decoratively treated with as much ease, eH-iciency, and effect as any other wall or ceiling surface. They could be painted, treated with plaster ornamentation, accented with molding, finished in natural effects, or in any one of a number of techniques.

But there would be occasions when it would be more practical to complete the decorations right in the factory where these units were being built. Here, after construction, the required structural sections can be finished to the desired color scheme while the surfaces are easier to get at, thus cutting down labor and attendant expense.

Shapes to Meet Each Need

Mr. Hanisch nodded assent to Mr. Teichertls words but felt he should interrupt to be a little more specific about one phase of laminated wood handling, that of the glued laminated arch. This, he felt sure, was of immense interest to architects specializing in theatre construction, or to theatre management contemplating building as soon as conditions permit, and should be explained most clearly. He went on to say that these arches, with comparatively simple engineering details, are available in any one of a number of types and a large variety of shapes to meet the specific structural needs for the complete support of a theatre. Roof. loads are independently supported and transferred directly to the footings, leaving sidewalls nonload-bcaring areas, which results in unrestricted freedom of design and use of materials. Besides having all the com l945-THEATRE


mendable features of laminated wood mentioned in general above, this type of arch makes new theatre construction amazingly quick, economical, permanent, safe, and acoustically correct.

As to the decorative qualities of these arches, Mr. Teichert noted that they can be emphasized or played down in the scheme of the interior as required by the over-all scheme. The very simplicity of the arches aids theatre decoration by providing freedom from cobweb trusses which interfere with ceiling height, treatment, lighting, and ventilation. Furthermore, this new construction combines functionalism with clean and uncluttered beauty of line.


Mr. Hanisch agreed and Went on to'say that the use of these arches makes it feasible to carry the discussion of the

importance of laminated w00ds to theatre construction even further. For inasmuch as this most serious of the engineering problems involved has already been met by the glued laminated arch, it is to be wondered if an all-wood pre-fabricated theatre is not in the very near future. Such a theatre, with glued laminated structural ribs as its backbone, would have panels of wood or other materials. Mr. Hanisch wanted to emphasize that this is not by any means a matter of theory.

Precision-Built Panels

This construction has proved itself to be of great practicability in all weathers, climates, and conditions. To document his argument, he goes on to say that of all the various systems of pre-fabricated construction he has seen, and his company has built, he is sure that the Unicon precision-built system is the most flexible and practical of the entire lot. A very large number of precision-built panels have been constructed in mass production for the Unicon Company, who hold the patent rights. These panels were used by various government agencies for buildings which were shipped into many parts of the world, and there they withstood the tests that have been mentioned with the utmost success.

But the Unicon system excels in another way, according to Mr. Hanisch, that is in its complete simplicity. Some of this simplicity includes the fact that the panels need not be especially marked, since they fit anywhere with no lefts nor rights, no tops nor bottoms; the standard panels will fit into walls, floors, and ceilings; and they are assembled with the aid of ingenious locking strips requiring the use of no tool other than 3.

FIRE RESISTANCE, wood versus steel, is eloquently set forth in this picture, used through the courtesy of the Casein Company of America. The laminated, l2xl6-inch beam proves that wood does not collapse: it holds until the cross section is actually reduced to the breaking point by steady flame, thus oftentimes allowing the valuable time in which to save the structure. A modern, glued laminated member, with fireestop inserts and treated or coated with fire-resistant material, would have showed for greater durability it is asserted.
