Abstract:

A corner assembly for concrete form panels has a pair of rigid members. Each member has a bend therein to form a selected dihedral angle. The members are spaced apart by a selected distance and a removable bridge is disposed between the pair of rigid members. At least one concrete panel form is juxtapositioned to and connected to each of the rigid members. One of the rigid members is disposed exteriorly of the at least one concrete panel form. Concrete is disposed interiorly of the at least one concrete panel form. The corner assembly is adjustable to provide support for the corner of the construction.

Abstract:

A corner assembly for concrete form panels has a pair of rigid members. Each member has a bend therein to form a selected dihedral angle. Each member has horizontal slots formed therein and receiver plates which are received in the slots and extend through the concrete panel forms. The receiver plates are connected by a bridge member. The members are spaced apart by a selected distance and a removable bridge is disposed between the pair of rigid members. At least one concrete panel form is juxtapositioned to and connected to each of the rigid members. One of the rigid members is disposed exteriorly of the at least one concrete panel form. Concrete is disposed interiorly of the at least one concrete panel form. The corner assembly is adjustable to provide support for the corner of the construction.

International Classification:

E04C 141

US Classification:

52426

Abstract:

A concrete assembly form having a plurality of panels adjoined to one another to form opposing walls. A plurality of studs are encased in each panel. Each stud has a truss structure for increased strength and has a plurality of cylinders extending from the inner face of each panel. The opposing walls are connected with a plurality of bridges, each having collars on the ends in which are seated the cylinders from the panels. U-shaped rods are connected between the cylinders. A hold-down clip connects the bridges between vertically oriented panels. A method of preparing the assembly is disclosed.
