Abstract: A tie rod suitable for use with a concrete forming system, comprising one or more button rod elements, wherein the button rod element has an elongated main body having a first end region having a head portion, an opposed second end region having an anchor portion, and an intermediate region, wherein the second end region or the intermediate region has one or more relatively flat cut-outs formed therein. The tie rod also includes a continuous fiber wound about the anchor point and the cut-outs to form the tie rod.

Abstract: Provided is a wiring unit that reduces spatial constraints and makes it possible to easily perform wiring work. The wiring unit is provided with: a plate on which a support surface for supporting electrical wires is formed; and a holding member for holding the electrical wires between the support surface and said holding member. The holding member comprises a plurality of holding pieces protruding from the support surface side. After being collapsed from an upright orientation in which the holding pieces stand upright so as to demarcate a guidance space in which the electrical wires are guided toward the support surface side, each of said holding pieces presses the electrical wires toward the support surface side and deforms toward a holding orientation in which the electrical wires are restricted from lifting up from the support surface.

Abstract: An adjustable beam sleeve device with two telescopically mounted first and second sleeve assemblies with movable bowl assemblies at the distal ends. The first sleeve and the second sleeve are selectively set in relative position by means of a screw to form a telescopic column. The bowl assemblies are urged towards each other by an elastic string that is kept taut to produce snug fit when the adjustable beam sleeve is used between forms used to contain the concrete when poured. After the concrete is poured, the string is cut or the knots at the ends are removed along with the bowl assemblies resulting in a passage through the poured concrete after it is cured.

Abstract: A holdown connection assembly for attachment to a form used to make a concrete foundation includes a holdown including an elongate plate member having an upper section with a plurality of holes sized and shaped to receive fasteners to attach the holdown to a wood frame member supported by the concrete foundation. A lower section extends from the upper section and is configured to be at least partially embedded in the concrete foundation when the holdown is attached to the wood frame member. A support is configured to be mounted to the holdown to attach the holdown to the form. The support includes a wire member engageable with the holdown for locating the holdown relative to the form when the support is mounted to the holdown and attached to the form.

Abstract: A twisted wire tie for concrete forming has an elongate loop with a single strand of wire on one side and a twisted double strand on the opposite side. Two stops on the tie are formed at opposite ends of the twisted double strand and engage the twisted strand and the single strand so as to prevent unwinding of the twisted strand when the tie is placed in tension.

Abstract: A tool for guiding a rod through a tie loop that is extending through a slot in a concrete form. The tool includes a rod guiding member defining an elongated channel extending longitudinally between front and back ends of the rod guiding member. The front end of the rod guiding member is preferably tapered to form a tab member for inserting through the tie loop. The tool also preferably includes a handle connected to the rod guiding member for grasping the tool. When the rod is driven longitudinally through the channel of the rod guiding member while the tab member is inserted through the tie loop, the rod guiding member pivots causing the tab member to pull the tie loop completely through the slot in the concrete form thereby allowing the rod to be guided through the tie loop.

Abstract: A prefabricated collapsible formwork module is assembled at a factory site, including the provision of a pair of sheathing panels which can be made of insulating material, as well as the mounting of the vapor barrier, the filler strips, bearing blocks, and flexible or collapsible connecting elements extending between the panels extending between the panels to retain the panels when they are being erected. The sheathing panels may also have a waterproof membrane applied thereto, and the concrete reinforcement is assembled between the sheathing panels at the factory site. When the formwork module is fully assembled, it is then collapsed, that is, by moving one sheathing panel against the other including collapsing the collapsible connecting elements and sandwiching the concrete reinforcement which is preferably in the form of a grid, and the formwork module can then be stored and transported to a building site.

Abstract: A spacer/tie rod to space and hold reusable sections of concrete molds is, according to the principal embodiment of this invention, constructed of two main elements and two auxiliary elements cut from the same small diameter steel rod stock. The main elements are identical, with each having an elongated central section and upturned indexing sections at each end, while the auxiliary elements are identical and straight. The latter are welded to the former at positions where the auxiliary elements are spaced apart by a distance equal to a wall thickness, and the distance between each auxiliary element and the main element indexing section nearest to said auxiliary element is equal to the thickness of the frame that stiffens a form section. The indexing sections of the main elements are tool bendable between form positioning and form holding positions.

Abstract: An improved heat insulated tie rod allowing to reduce local heat insulation defects of concrete or stratified, concrete wall members. The tie rod includes stoppers for setting and holding together a pair of frame walls in spaced apart relationship with, if desired, a heat insulating panel therebetween. The tie rod is improved in that it is made of two coaxial portions connected to each other through a central, heat insulated body having a high resistance to crushing. Preferably, each tie rod portion has a looped end surrounding the central body which can be a block of hardwood.

Abstract: In a recoverable form for use in the region where a tendon is anchored in a prestressed concrete component, a part is provided for forming a cup-shaped recess in the concrete surface. The part contains an axially extending passage through which a tendon extends. The part is formed of rubber or a rubber-like material and is constructed so that its outer surface extending in the direction of the passage arches outwardly away from the passage when a compressive force is applied to the part in the axial direction of the passage.

Abstract: Two abutting predecorated gypsum wallboards, being adhesively affixed to preformed sheet metal framing members, such as studs, are temporarily held firmly against a stud, which is disposed behind the joint between the two boards, by means including an elongate flat block disposed against the face of the board edges, a tie wire and a small arcuate wire guide, with the tie wire extending from one end, near the outer face of the block, to between the wallboard edges, through one hole in the stud, around the arcuate guide, back through another hole in the stud, out between the wallboard edges to the other end, also near the outer face of the block. The two wire ends are arranged to urge the block tightly against wallboard, when the two wire ends are twisted together. Removal of the wire and block involves cutting one leg of the wire, adjacent the block, and then pulling the wire out of the wall by pulling on the other wire leg.
