Abstract: A method and apparatus is disclosed for forming insulated walls by pouring concrete directly on a form made in part of insulating material which will remain in place after the concrete sets. An apparatus for spacing the sheets of insulating material from the sheets of other material to create a concrete form is also disclosed, which also provides the function of bringing adjacent sheets of insulating material to create an adequate seal for the concrete. A tie holder for supporting cross members is also disclosed.

Abstract: A gang form or tie rod holding bolt is adapted for holding a tie rod passing through abutting frames of prefabricated panel units, the frames having mating slots. The tie rod holding bolt includes a body portion and a slot leg for extending through the mating slots, a middle leg for loading the frames, and a tie rod engaging leg for transferring a load from the tie rod to the holding bolt. The form slot leg and the middle leg are horizontally offset to straddle the tie rod and the middle leg is adapted to transfer the load to the frames, thereby providing the bolt with great stability under heavy loads. The design avoids eccentric load on the bolt. An assembly includes the bolt, tie rod, wedge pin and two frames.

Abstract: Concrete form systems and hardware components thereof wherein the inner and outer walls are composed of abutting, side-by-side plywood sheets and are tied together by wall ties and stud-bearing plates, wherein the improvements reside in: metal straps serving as inside and outside corner braces with right angled legs having specially spaced, transverse, tie-rod-receiving slots in one longitudinal edge of each leg; rectangular plates having a center hole and two studs projecting from its inner face on opposite sides of the hole, said plate having longitudinal, flange edges or lips forming the sides of a trough in the outer face; flat, metal straps for securing filler strips between plywood panels, which straps have specially spaced, transverse, tie-rod-receiving slots in one longitudinal edge; and hingedly connected, rectangular panels forming a right angle corner for the outside wall, said panels being foldable to a shipping and storing position in which the panels are in overlying, substantial face-to-face pa

Abstract: A formwork panel for constructing concrete walls having a forming skin supported by a steel frame in which a plurality of holes are provided for receiving a tie rod. The holes are provided with a plastic bushing which extends through and is fastened in the frame. The bushing has a conically tapered bore, the surface of which is continuous and smooth. This makes the removal of concrete from the bore extremely easy (FIG. 3).

Abstract: A concrete wall form includes a support structure comprising a beam capable of functioning as a stringer or stiffback and which includes a bolt holding channel, a nailer channel and an internal channel for telescopically receiving an extension splice. A tie rod locking system is associated with the support structure for readily adjusting the forms.

Abstract: An improved concrete form and tie rod, the concrete form and tie rod being constructed to facilitate disassembly of concrete form assemblies. The tie rods and concrete forms and structured to permit the ends of the tie rods to be broken off following completion of the concrete casting process to thereby facilitate removal of the aligning pins which hold the concrete forms of a form assembly together.

Abstract: A concrete construction system and method for erecting building structures in which column casting molds are assembled from a plurality of modular, interlocking, reusable forming elements, and in which the precast columns are provided with anchoring elements embedded in one end of the column. Support footings are cast in situ using reusable form components to provide a structure accommodating direct placement of precast support columns and precast wall panels. A framework of adjustable joist assemblies provides support for construction of the roof or upper level floor structure.

Abstract: A tie rod assembly to secure form panel elements in edge to edge engagement and tie opposed panels made of such elements in spaced apart relationship. The assembly employs a tie rod having a length less than the distance between the opposed panels and gripper mechanisms releasably engageable with the ends of the tie rod and proportioned for extension through tie rod openings formed in the panels. Key elements are engageable with the gripper mechanisms and the panel elements to lock the mechanisms in engagement with the rod and secure the panel elements in place. The rod is provided with enlarged heads at either end thereof for engagement by the gripper mechanisms and, in a preferred embodiment, the sides of the head are flattened.

Abstract: The specification discloses concrete forms each including a plurality of rectangular panels secured edgewise together by connectors. Each connector includes a pair of half sleeves secured in a pair of grooves in the edges of the panels, and a cupped head of a connector sleeve wedges the half sleeves together to hold the panels in edgewise abutment. A nut screwed on the connector sleeve draws the cupped head into wedging engagement with the half sleeves. Tie rods extend through the connector sleeves. The panels include wood framing having plywood faces and filled with foamed plastic.

Abstract: A concrete wall form structure of the type having a pair of aligned contiguous pre-fabricated panel units disposed in an edged-edged, upstanding relationship. Each panel unit has one of its marginal frame members abutting an adjacent marginal frame member of the panel unit. The panel unit edges have a plurality of aligned apertures in each of the abutting frame members whereby at least two apertures of abutting frame members are aligned and receive an elongated bolt. One of the panel units slidably carries the bolt so that it is movable between a retracted rear position wherein the bolt is moved within the confines of that one panel unit and an advanced forward position wherein the forward end of the bolt is projected through both apertures of the adjacent frame members and within the confines of the other panel unit.

Abstract: A concrete wall form includes a support structure comprising a beam capable of functioning as a stringer or stiffback and which includes a bolt holding channel, a nailer channel and an internal channel for telescopically receiving an extension splice. A tie rod locking system is associated with the support structure for readily adjusting the forms.

Abstract: A clamping lock is provided for use with a looped tie in a form for settable casting compositions, such as concrete, which lock is provided with protrusions on each of a pair of clamping members to fit into aligned connector slots of a pair of rails of adjacent panels of the form to properly position and firmly secure the lock to the form. The securing of the clamping members on the rails also holds adjacent panels of the form together. The rails are provided with tie notches which when panels are placed side by side and properly aligned the tie notches form tie slots through which a tie having loops at each end can be extended between panels of opposing sides or walls of the form structure. A tie opening is formed in the clamping lock through which the loop of a tie is adapted to extend. An anchor lock having a tapered arm is mounted on the clamping lock so that its arm can enter into a tie loop extending through the tie opening to secure the tie to the clamping lock and to tension the tie.

Abstract: The invention relates to a shuttering system which has a series of connector or distance elements, the elements having formations which receive complemental formations in the shuttering panels, the portions outside of the formations being capable of being broken off or removed when the shuttering panels are removed, leaving the remainder of the element in the wall.

Abstract: A form for concrete which has inner and outer walls spaced apart. Each wall is formed by a plurality of vertical elements abutting each other vertically. A row of whaler lookout plates are mounted on the abutting sides of the vertical elements and support a whaler rod which holds the vertical elements together to form a wall.

Abstract: Metal wall form sections are adapted to a bolted tie system providing accurate spacing of the opposite panels defining a space to receive poured concrete. In the preferred form of the invention, interengagement of the form structure and the tie system (providing the spacing feature) is also used to secure the form sections laterally to each other. In another form of the invention, wedges transversely engaging the bolts bridge across and bear on the flanges of marginal beams of adjacent form sections to establish relative placement against the pressure of the concrete.
