Each corrugated sheet has a horizontal reinforcement member rigidly attached to the internal side of the corrugated sheet wherein a horizontal reinforcement member is an L-shaped angle steel having a plurality of connecting holes on its horizontal element. A plurality of uniting rods are used to connect two opposing wall panels by inserting each end of the uniting rod into the connecting holes of opposing horizontal reinforcement members. A connecting bar assembly is used to more securely connect two adjacent wall panels.

  • Patent number: 6314694
    Abstract: One-sided, insulated formwork used in the construction of walls from pourable building material, such as concrete, including an insulating panel connectable to a removable panel by a connecting structure, which may include a permanent reinforcement embedded in the insulating panel. The connecting structure may have a tie removably attachable to the reinforcement, or the reinforcement and tie may constitute a monolithic structure. The tie may be asymmetric in shape to facilitate distribution of loads across the insulating panel, detachment of the removable panel, and enhance the structural integrity of the finished wall.

  • Patent number: 6224031
    Abstract: A tie includes an elongated strap with an end plate pivotally connected at each end of the strap, permitting the end plate to be pivoted from a position generally orthogonal to the strap, to a position generally parallel to the strap. Once an end plate is pivoted to a position parallel to the strap, the end plate can be pushed through a polystyrene form panel to project therefrom. The end plate is then pivoted to the position orthogonal to the strap, and pulled into engagement with the outward face of the form panel. The second end plate on the tie is pivoted, pushed through a second form panel, pivoted to the orthogonal position, and thence the second form panel is pulled outwardly into contact with the second end plate. In this way, the tie will interconnect a pair of parallel form panels in spaced apart position, to receive poured concrete therebetween.

  • Patent number: 6202978
    Abstract: A side wall system for a concrete casting mould, including a side part (2, 3) which is removably attachable to a casting bed (1) by means of one or several magnets (7). The body (6) of the magnet part that carries the magnet (7) includes a pivoting shaft (10) about which the magnet part (6, 7) can be pivoted into a lower position wherein the magnet (7) is fastened to the casting bed (1) and into an upper position wherein the magnet is spaced from the casting bed. The side part (2, 3) includes a holder (5) on which the pivoting shaft (10) of the magnet part can be hung so that it can be pivoted between its lower and upper positions. The holder (5) has a mounting face to which the upper surface of the magnet (7) can be fastened by means of the magnetic force when the magnet is pivoted into its upper position about its pivoting shaft.

  • Patent number: 6173937
    Abstract: Standard height wall form panels for poured concrete walls are extended with cap panels positioned on top thereof and secured thereto with cap clips which can be conveniently and easily installed and disassembled with the wall form panels. Furthermore, a spreader is used to maintain the spacing of the cap panels and provide a uniformly dimensioned concrete wall. Advantageously, the spreader in one embodiment allows a worker to pass a trowel there beneath to smooth out the top surface of the poured concrete wall.

  • Patent number: 6164618
    Abstract: The present invention relates to a joining method and a joining structure as well as a form for concrete products. A protruding portion provided at the front end of a seal member of elastic material attached to one concrete product is inserted through an opening formed in a joining face of the other concrete product into an attachment hole of enlarged diameter provided at a depth of the opening, while bringing a closing press contact portion of the seal member into press contact with inner surfaces of the opening to achieve an airtight condition inside the attachment hole, followed by filling grout into a space defined between inner surfaces of the attachment hole and the protruding portion and setting the grout there to join the concrete products together.

  • Patent number: 6079176
    Abstract: A system for insulating only the interior surface of a concrete wall to be poured between a pair of interior and exterior wall forms. The system includes horizontally extending elongated tie strips which connect to each of the wall forms to hold the wall forms spaced apart, a single layer of insulation positioned in contact with the interior wall form, and a plurality of connectors for securing the single layer of insulation to only the interior surface of the concrete wall. The connectors include an enlarged head portion which engages the insulation and a web portion of smaller cross section which extends through apertures in the insulation and into the space between the wall forms, the web portion including openings for the passage of concrete therethrough.

  • Patent number: 6059256
    Abstract: The invention provides a bulkhead forming system and method for forming a bulkhead. The bulkhead forming system comprises a number of individual forming members which are coupled together end to end and opposing each other to provide a gap therebetween on which the concrete is poured. The individual forming members consists of straight side forming members, 90.degree. internal angles, 90.degree. external angles, and other angled matched pair forming members, each of the said forming member having a substantially deep continuously concave indentation extending horizontally through the forming member, resulting in a substantially sideways U-shaped cross-section. Each surface of the bulkhead forming member is provided at an angle at which the frame can be easily released from the bulkhead once cured. The resulting freestanding bulkhead provides a useful walkway or work surface. Pilings may be driven into soil and placed between the opposing frames to provide additional stability or to create a boat lift.

  • Patent number: 5987830
    Abstract: An insulated concrete wall is constructed by securing at least one tie assembly (14) to a panel (12) of insulative material, securing the tie assembly and panel to a pair of spaced forms (60, 68), and pouring concrete into an open space defined by the forms adjacent the panel. The concrete is then allowed to set, and the forms are removed. The tie assembly (14) includes an elongated tie (16) having a central region (24) adapted to remain in place in the wall subsequent to construction and a pair of opposing end regions (26, 28) adapted to be detached after removal of the forms. In addition, the assembly (14) includes an elongated retainer body (18) formed of heat insulative material and received on the tie (16), and a pair of face plates (20, 22) retained on the body on either side of the panel (12).

  • Patent number: 5861105
    Abstract: A concrete form system is disclosed, together with a method of assembling it and particular ties useful with it. The system has a concrete form with two opposed walls and a cavity between to be filled with concrete. One wall is made of conventional wood or metal panels. The other wall is made of foam panels. Vertical joins between plywood or metal panels are directly opposite vertical joins between foam panels. The system provides ties to join the two walls and brackets or retaining members to spread the forces on the ties so they do not pull out of the foam wall.

  • Patent number: 5794394
    Abstract: A flat plate is used to cover a mounting hole in a masonry wall face and is held in place by a set of wire hooks. The hooks are able to slide into holes in the plate and catch onto the interior surface of the wall in order to hold a clearance hole in the plate concentrically with respect to the mounting hole. An anchor bolt is supported at the center of the mounting hole by the clearance hole in the plate while grout is poured into the masonry blocks thereby assuring that the bolt is positioned properly in accordance with building code.
