By engaging a connecting member to an element, the outer side of the element, the extension of the element and the outer portion of the connecting member form a triangular space providing structural rigidity to the formwork.

  • Patent number: 5695676
    Abstract: A modular form assembly includes a plurality of vertical channel pieces coupled detachably side by side to one another. Each of the channel pieces includes two opposing vertical side walls and an intermediate vertical form wall which interconnects the side walls. The side walls of each of the channel pieces abut against and are attached detachably to the side walls of adjacent two of the channel pieces such that the form walls are arranged in a side-to-side contiguity in order to place the form walls in a common vertical plane. Each of the form walls is formed with at least one through-hole therethrough. Each of a plurality of cover plates is mounted removably on one of the form walls to cover a respective one of the through-holes. At least one of the cover plates is formed with at least one positioning hole therethrough.

  • Patent number: 5692356
    Abstract: Apparatus, method and product of in situ attachment of insulation panels to poured concrete walls as the walls are formed. Polymeric F-shaped strips are attached to novel tie bars by spring clip retainers, and receive the edges of insulation panels to hold them against the forms so that uncured concrete is poured between the forms and against the panels. After the concrete is cured, the forms are removed, leaving the spring clips and tie bars in the concrete, and resulting in a concrete wall having insulation panels and secured strips, the strips also serving to receive dry wall fasteners.

  • Patent number: 5580480
    Abstract: A form for making a concrete fence post supported by the ground is disclosed. The form has two elongated halves which are hinged together and clamped along one edge. The form is supported over a post hole and concrete is poured into the form. Reinforcing bars or mesh is inserted in the wet concrete and the concrete is permitted to set. The form is then opened and removed resulting in a reinforced concrete fence post. The process of using the form is also disclosed.

  • Patent number: 5535982
    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.

  • Patent number: 5509636
    Abstract: A retainer clip for use with concrete form tie for retention of reinforcing rods has a one-piece body which includes a header, and first and second clips extending angularly therefrom, spaced apart in a first direction, and defining therebetween a generally u-shaped opening sized to slidably receive a reinforcing rod of generally circular cross section. Each of the clips include first and second prongs spaced apart in directions lateral to the first direction, and at least two prongs of the clips further define therebetween a narrow generally rectangular passage which intersects at least a portion of the u-shaped opening, and is sized to receive at least a notched form tie of generally narrow rectangular cross section. The retainer clip secures the reinforcing rod in position substantially against the form tie in a notch to inhibit both relative motion in the first direction and substantial separation therebetween.

  • Patent number: 5431368
    Abstract: A tie for concrete wall form assemblies, adapted to secure individual wall forms together, and to secure horizontal reinforcing members against both horizontal and vertical displacement. Upwardly opening notches accept and position the reinforcing members. The notches are sized and shaped to permit inversion of alternate ties along the form structure, to restrain reinforcement movement downwardly, upwardly and laterally.

  • Patent number: 5405119
    Abstract: A sleeve assembly for forming a lined opening in molded structures made from concrete or the like. The sleeve provides the lining. During formation of the structure, the sleeve is held in place by a pair of generally hemispherical end cups having tapering and/or curving surfaces for supporting sleeves of a variety of sizes. The end cups are preferably held in place by a retainer which passes through the sleeve and is connected to the end cups by loose fitting clips which are mounted in the end cups. The sleeve assembly is adapted to be secured between a pair of generally parallel panels between which a molded structure such as a wall is formed.

  • Patent number: 5375809
    Abstract: A poured concrete wall construction. In forming the wall construction, a back panel is mounted on a foundation and a plurality of generally rectangular thin-walled blocks formed of crushed stone bonded with a thermosetting resin are stacked to form a wall that is spaced from the back panel with a cavity being defined between the stack and the back panel. A tubular frame is positioned outwardly of the stack, and a plurality of connecting members connect the back panel and the frame and extend through mating notches in the edges of adjacent the blocks. Clamps are connected to the outer ends of the connecting members to connect the connecting members to the frame. Concrete is subsequently poured into the cavity between the backing panel and the block stock to form the wall construction with the stack of blocks forming an outer decorative face for the wall.
