Corner forming apparatus is disclosed, including novel generally L-shaped member having a seating flange projecting from one leg of the member substantially parallel to the other leg. The seating flange is adapted to shield an edge of a panel when the panel is seated on the seating flange. The other leg of the L-shaped member is securable to a panel-support beam mounted on the back of said panel, and is provided with at least one aperture therein to receive fastening elements for securing another panel to the other leg such that a surface of the other panel and the outer surface of said one leg are substantially coplanar. Also a unique outside corner waler useful with the inside corner forming member in quick and accurate assembly of a complete corner wall form. Said waler having a major leg and a minor leg each joined at one end at right angles by an apertured web and being of respectively different heights such that said waler seats at about a 45.degree. angle.
An inside corner concrete forming member adapted for mounting on a free end of a first wall form panel and on at least one panel-support beam member fixed to such panel, said corner forming member being substantially L-shaped and having a seating flange projecting inwardly generally at right angles from an intermediate location along one leg of said L-shaped member, the extension of that portion of said one leg beyond said seating flange being substantially equal to the thickness of said panel and being adapted to shield said free end of said panel when the latter is seated at right angles to said one leg on said seating flange with said end abutting said extension;
An inside-corner forming member for joining a pair of wall forms at right angles comprising an L-shaped elongated metal member having one leg with a rectangular planar outer side surface and a rectangular planar outer end surface which surfaces join together at right angles and define the inside-corner joint, first fastening means on the other leg closely adjacent to said one leg for use in demountably joining a wall form with its outer surface coplanar with said side surface of said one leg, second fastening means closely adjacent said end surface of said one leg for use in joining a separate wall form to said L-shaped member with the outer surface of said separate wall form being coplanar with said end surface, and a third fastening means for use in joining said other leg to said separate wall form remote from, yet offset in the general direction of, said second fastening means.
An inside-corner forming member for joining a pair of wall forms at right angles comprising an elongated L-shaped extruded aluminum member having one leg with two planar outer longitudinal surfaces which are at right angles to each other, said other leg having a first portion extending inwardly at right angles from its joinder with said one leg and having a further portion offset to the side in the direction of said one leg for stripping clearance.
An outside-corner waler for a concrete wall form comprising a U-shaped channel having a pair of parallel major and minor legs joined at right angles by an apertured top web, said legs terminating at their free ends in flanges coplanar with each other, said legs being dimensioned with relative lengths such that said web makes about a 45.degree. angle with the plane of said flanges.
An inside concrete form assembly, comprising a substantially L-shaped aluminum member having a seating flange projecting inwardly generally at right angles from an intermediate location along one leg thereof, the other leg of said L-shaped member having a first portion which extends from said one leg at substantially a right angle, an angle portion that angles back on the side towards the said seating flange, and a second portion substantially parallel to said first portion and joined thereto by said angle portion;
