摘要： This invention pertains to a low cost adjustable form that can be adjusted for forming various types of two-way curved, precast, reinforced thin shell cementitious and plastic panels for small spanned building shells having uniform scalloplike, corrugated shells like the shells shown in my U.S. Pat. No. 3,154,888 and to the method of making the same. The form can be adjusted so as to mold different original types of panels, that differ by having different curvature, and/or different size. The form has a base with an adjustable template frame. A thin reinforced base coating is mounted within the template frame. An elastic edge form that is like a gasket, is secured to the template frame with metallic fasteners. The elastic edge form molds a keying groove in the panel edging. The fasteners position reinforcing and clevis connectors that are attached to the reinforcing, to allow like panels to be easily joined with pins at erection, even during inclement weather, the keying grooves allowing the panels to be keyed together with grout when the weather is suitable.

摘要： A form for casting structural units of the type involving at least a concrete slab and side beams and may include end beams and corner legs, the form including beam casting forms slidable a limited distance on an underlying surface between a casting position and a clearance position, each beam casting form being itself a concrete structure secured to the underlying structure by steel straps the extremities of which are anchored in the beam casting form and the underlying structure, whereas the central portions are encased in an elastomer to permit limited movement of the beam casting form.
