    Abstract: A method is proposed for constructing multi-story concrete structures using a rail-guided self-climbing formwork system. A climbing rail is thereby displaced in a vertical direction within lower and upper climbing shoes and a lower extension piece is positioned to extend vertically in a downward direction below a lower end of the climbing rail. The lower extension piece has a length which is less than the length of the climbing rail. The climbing rail is then displaced in the vertical direction until the lower extension piece is captured within the lower climbing shoe. The method simplifies construction of the lower stories of concrete structures.

    Abstract: A forming system includes a frame and two forming walls. The two forming walls are positioned at a distance from each other to define a first vertical wall course. One forming wall is supported by the frame such that the one forming wall can be translated toward or away from the respective other forming wall. The frame can be raised to raise the two forming walls to be positioned to pour a second vertical course on top of the first vertical course. The translation of the one forming wall allows for the pouring of the first vertical course with horizontally extending rebar that extends through the one forming wall outside of the first vertical wall course, to tie in to a subsequently poured floor slab. The translation permits the vertical raising of the one forming wall, without striking the extending rebar, to pour the second vertical course on the first vertical course. A worker's platform is provided that is supported by the frame and vertically movable by raising the frame.

    Abstract: A forming panel is provided which includes at least one and preferably a number of elongated channels each having inwardly projecting ribs which permit threadable attachment of hardward components such as bolts, externally threaded rings, collars and the like directly to the channel along an infinite number of locations. The channels may be parallel to one another, perpendicular to one another, or both. The forming panel may be used with other forming panels and are configured to receive therethrough anchoring members such as anchor bolts and tie rods which pass into the gap between opposed forming walls where concrete is poured. The forming panels may be used as cap forms whereby after the concrete is cured, forming panels below the cap form may be replaced and reattached above the cap form.

  • Patent number: 7114305
    Abstract: A hybrid arched overfilled structure includes a combination of pre-cast side elements and at least one cast-in-place crown sector element. The side elements are pre-cast generally in a horizontal orientation and subsequently lifted into place. The crown sector element is cast in place between the side elements. In one form of the invention, each of the three sections makes up about one-third of the overall arch span.

  • 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: 6954974
    Abstract: In a method of constructing a rail track on a concrete slab, the concrete slab is poured around anchor members for fixing tie plates supporting the rails of the rail track. The method includes the following steps: suspending the rails premounted on their tie plates above the location at which the concrete slab is to be poured, each tie plate including a base under which is disposed a temporary tie plate for accurately guiding the anchor members, adjusting the position of the rails, pouring the concrete slab up to the height of the temporary tie plates, raising the rails and removing the temporary tie plates, and accurately positioning the rails premounted on their tie plates on the concrete slab in their final position and fixing the tie plates to the anchor members.

  • Patent number: 6926851
    Abstract: A method is provided for use of a concrete composition and an associated apparatus. The method provides for mixing of the concrete material, accelerant powder and, optionally, an associated substance to enable the controlled hardening of the concrete material in a monolithic structure. The apparatus can dispose a slip-plane film to facilitate a relatively continuous process.

  • 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: 6913717
    Abstract: A method of constructing a rail track in which a concrete track slab is produced and rail track anchor members are inserted in the track slab by an inserter system mobile along the route of the rail track includes the following steps: using a machine for continuously pouring concrete to produce two concrete walls laterally delimiting the edges of the track slab to be poured; pouring the concrete track slab between the walls; and using the inserter system to insert anchor members in the freshly poured track slab, the tie plate inserter system being adjusted accurately by a measuring station, topographical survey points, a measuring system, and reflectors carried by the inserter system.

  • Patent number: 6911165
    Abstract: A method is provided for fabricating a concrete slab in a substantially horizontal slip casting process method, concrete mix is fed into a mold through a delimited cross section moving progressively in the casting process so as to form a concrete product of a desired shape. Onto the surface of the casting bed (1) is placed a core (3, 9, 10, 11) capable of delimiting the cross section of the concrete product (5, 5?) so as to provide an opening or a provision for an opening in the bottom surface of the slab. A core is provided for obtaining an opening or a provision for an opening. The structure and/or material of the core is/are such that the core is capable of yielding in vertical direction. A core may also be a multipart core, the outer part of which becomes detached from the inner part of the core in conjunction with lifting off the concrete slab from the casting bed.
