  • Patent number: 11982059
    Abstract: A bracket attachable to a top side of a parapet on a bridge to support a platform positioned on a horizontal element of the bracket. Vertical adjustment of the bracket allows the horizontal element to be positioned a small distance beneath the bridge deck so that the platform positioned thereon can catch falling materials, such as from demolition during bridge repair. After demolition, vertical adjustment of the bracket brings the horizontal element supporting the platform to a level directly under the bridge deck for use as a formwork for construction of a new roadway.

  • Patent number: 8959862
    Abstract: The present invention discloses a method and a forming system that reduces the hydrostatic pressure caused by casting freshly mixed concrete or other cementicious material into vertical forms. Reducing the hydrostatic pressure in forms enables relatively weak materials to be used as form boards and minimizes the amount of bracing necessary to support the form boards—both of which lead to lower construction costs. The method uses the highly thixotropic properties of no-slump or low-slump concrete which enable the concrete to be quickly changed from a semi-solid state to a liquid and back to a semi-solid state numerous times before it hardens and without affecting the concrete's quality. Since hydrostatic pressure is only present when a liquid state exists, minimizing the amount of liquid concrete in vertical forms will also minimize the hydrostatic pressure present.

  • Patent number: 8757593
    Abstract: A dual ratchet pawl jacking system, device, and method are presented for raising and/or lowering a platform bearing carriage along a vertical support. The ratchet pawls alternate supporting the weight of the carriage by engaging against a series of lugs on the vertical support. A first pawl is attached to the main frame of the carriage, and a second pawl is attached to a sub-carriage assembly that slides upward and downward within the carriage frame. A hydraulic jack applies a force upon the sub-carriage, causing the sub-carriage to move within the frame. The weight of the carriage is alternately borne by each pawl as the other pawl is relocated to a new lug. A pair of triggers is used to retract the first pawl and second pawl from the support. The triggers may be enabled to facilitate lowering the carriage, or disabled to facilitate raising the carriage.

    Abstract: A vertically adjustable overhang bracket uses an elongate base component adapted to be supported from a support column. A frame member is slidably secured to the base component to allow movement of the frame along the length of the elongate base component. The frame is of a shape to provide an outwardly extending support member for supporting concrete formwork members to one side of the base component. An actuator controls the position of the frame, relative to the elongate base component. With this arrangement, concrete formwork can be more easily supported in a cantilevered manner from support columns and vertically adjusted quickly to the proper position. Removal of the formwork is simplified as the frame can be lowered, relative to the base component providing clearance for removal of the bracket and the formwork.

  • Publication number: 20090071092
    Abstract: A prefabricated form assembly for making a concrete floor is disclosed. The form comprises an elongated form plate having a front for forming and retaining a flowable concrete material before it sets, anchor elements extending from the back face of the form plate, and being destined to be embedded into the concrete floor; and an L-shaped lintel having a back wall connected to the front face of the form plate and a bearing wall for supporting a masonry wall. Advantageously the construction of a concrete floor adapted to structurally retain a masonry wall using prefabricated form assemblies according to the invention no more requires the use of different groups of workers from different building trades as in the prior art, only one group of workers is required.

  • Patent number: 7073306
    Abstract: This is an improved method of building with fibrous material though other materials can be substituted. A binding secures fibrous material to form a wall assembly (10). Wall surfacing (20) can be included in the binding and forming process, reducing the labor required to apply it. Other building features and components can also be included in the binding and forming process such as electrical wiring, furring strips, windows, doors and structural reinforcing. This method vastly reduces the difficulties encountered when installing these components. The versatility of the method also allows for attributes such as flat wall surfaces and variable wall thicknesses, which are difficult to achieve using baled fiber.

  • Patent number: 7070158
    Abstract: Formwork for erecting a crown on a top end of a structural concrete column of a highway bridge is supported by a pair of vertically positioned elongated jack-screws. Lower ends of these jack-screws are threaded respectively into adjusting nuts seated on outer ends of respective horizontal arms of a pair of brackets. Each bracket includes an upright support member. These members are attached respectively to opposite sides of the column. The vertical location of the formwork attached to an upper end of a jack-screw may be adjusted up or down by selective rotation of the adjusting nut into which that jackscrew is assembled.

  • Patent number: 7048249
    Abstract: Disclosed is a formwork element (1) which can be assembled with other formwork elements (1) so as to form a formwork structure. A formwork shell (4) having an adjustable curvature is supported by means of back supports (5) so as to create a stiff formwork element (1) that sustains concreting pressure. The supports (5) have a preferably trapezoidal cross section and are provided with fastening flanges (6) on the edges thereof and at least one girder (7) that is located at a distance from the formwork shell (4). The length of the girder (7) is adjustable in order to set or modify the curvature of the formwork shell (4) which is mare of steel or plastic. Intermediate pieces (9) are disposed between the fastening flanges (6) of the supports (5) and the formwork shell (4). The fastening flanges (6) are fixed to said intermediate pieces (9) so as to be pivotable or tiltable relative thereto about the longitudinal direction thereof.

  • Patent number: 7004737
    Abstract: An apparatus for forming concrete structures includes a first truss module and a second truss module, as well as a first and a second concrete form. The apparatus further includes a first and a second actuator device. Each first and second actuator device is mounted on the respective first and second truss module, and each first and second actuator device can move the respective first and second form translationally with respect to the respective first and second truss module. A yoke connects the first truss module to the second truss module to thereby place the concrete forms in generally parallel, spaced-apart relationship. A climbing device attached to the yoke can engage a climb rod and can move the apparatus upward along the climb rod.

  • Patent number: 6921501
    Abstract: A method of forming a circumferentially closed wall having the same cross-section over its entire length included providing at least two circumferentially closed inner falseworks each formed of circumferentially closed inner part and a circumferentially closed climbing strip releasably securable to an upper end of the main part. A concrete wall is formed in a plurality of concrete-placing steps, with use of the inner falseworks in more than one step. In a first concrete-placing step, an initial section of a concrete wall is formed. In each subsequent concrete-placing step, a circumferentially closed concrete wall section is formed on an upper end of an already formed section of the concrete wall.

  • Patent number: 6770228
    Abstract: A method for successive concrete of high vertical walls by using a climbing shuttering system having a support structure on which various concrete shuttering elements are loaded hanging downwards. The top supporting carrier and the climbing shuttering system can be supported on completed wall sections. There is at least one lifting device that brings about a relative movement between the too supporting carrier and a lower support carrier of the climbing shuttering system. The shuttering elements can be positioned in a substantially even surface to form a shuttering and at the same time the top supporting carrier can be positioned on the shuttering elements placing them respectively against the walls.
