    摘要: A form panel with a marginal wall for casting castable material, which has an edge to be positioned near an external surface and a fixed support for attachment to the form panel, fingers movably carried by the fixed support and movable relative to the edge of the form panel between an extracted and retracted position. The fingers extending beyond the edge of the form panel edge in their extracted position, the fingers having a load-bearing surface for retaining castable material slurry, and an actuation mechanism for moving the fingers between the positions. The fingers are movably carried by the fixed support such that at least some of the fingers are movable with respect to the others for forming a marginal barrier between the edge of the form panel and the external surface.

    摘要: Disclosed herein is a concrete form apparatus that can be utilized to establish a rigid perimeter within which concrete can be poured for curing. A first component of the concrete form apparatus can be composed of a flat rigid material that is rectangular in shape and includes perforations along the lengthwise dimension of the material such that, when the material is folded along the perforations, an internal cavity is formed. The second component of the concrete form apparatus can be composed of a material having dimensions sized in accordance with the internal cavity of the folded material such that the first component can be folded along the perforations in the manner described above to encapsulate the second component within the internal cavity. Adhesive layers can be applied to prevent the concrete form apparatus from separating, and layers of the concrete form apparatus can be coated with a waterproofing substance.

    摘要: A system for retaining a flowable and curable building material to form a portion of a foundation includes side walls disposed in a predetermined configuration having a first side wall and a second side wall, and at least one component having an interior cavity disposed in one of the side walls. A bracket assembly includes an outwardly bounding reinforcement post for each of the side walls, a separator bar having a plurality of apertures sized to receive and retain each of the reinforcement posts at locations corresponding to nominal widths of the at least one component. A barrier is disposed between the outwardly bounding posts. The barrier and the component in the side wall is retained in the foundation after the building material cures. The barrier prevents backfill from filling a volume between the outwardly bounding posts.
