Abstract:
A formwork assembly for a poured concrete structure includes a plurality of formwork panels and girder-like members for supporting the panels. The panels comprise a concrete surface forming sheet and laterally spaced flange-like support members on the outside surface of the panel. The panel sheet is formed of an elastically deformable material so that the panel can follow the configuration of a curved surface of the concrete structure. The support members on the panels are notched or recessed at their ends so that the aligned support members on adjoining panels form a cutout to which the girder-like member is secured.
Abstract:
A formwork component for the erection of cast structural walls, particularly for the erection of concrete walls. The formwork components includes a formwork plate with stiffening elements, for example, frames or girders, being mounted at the rear side of the formwork plate. Rails are provided on at least two oppositely located edges of the formwork plate. When several formwork plates are located next to each other or one above the other, the rails are located next to each other. The rails are connected by connecting elements, such as screws, clamps, or braces. Positioning, elements are provided on the rails. The positioning elements are projections and abutments which receive the projections and have a shape corresponding to that of projections.
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.
Abstract:
A formwork arrangement for erecting a structural wall of castable material, for example, of concrete. The arrangement includes at least one work platform and formwork plates which have a large surface area. For erecting the structural wall, the formwork plates and the work platform are progressively vertically raised by the height of the formwork plates. A support frame which extends parallel to the platform is provided above the formwork plates of a formwork section. Horizontally extending rails which are horizontally spaced from each other are mounted on the support frame. The rails can be swiveled about a vertical axis. A carriage is slidably mounted on each of the rails. Each carriage has a suspended anchor member on a side facing the formwork plate. The anchor member can be connected to an upper edge of the formwork plates.
Abstract:
A method of lowering a floating body of a floating foundation and carrying a structure projecting above the water surface to an end position located beneath the water level, includes threading, through each of the upwardly projecting tubes, which are secured to the floating body above-through-openings formed in the floating body, a cable or a rod and connecting the cable or rod to a set-in-ground anchor, lowering the floating body, with the uptake devices provided at the free ends of the tubes, to the end position of the floating body beneath the water surface against buoyancy of the floating body, and fixidly securing the cables or rods, in the end position of the floating body, to the floating body and cutting off sections of the cables and rods above fixation points of the cables and rods with the floating body and removing the tubes.
Abstract:
A form for erecting structures having an plan shape, any generatrix and possibly changing wall thickness includes an inner form (1) and an outer form (2). Circumferentially closed support rings (5,6) are arranged horizontally spaced from the inner form as well as from the outer form. Radially aligned sleeves (35) are provided in the support rings (5,6). Threaded spindles (7,8) are slidably but fixedly held in the sleeves (35). One end of each threaded spindle (7,8) engages form carriers (11,12) which rest against the form carriers (3,4). The inclination of the form plates (3,4) or the wall thickness of the structure to be erected can thus be adjusted. Web members (13,14) are provided between the form plates (3,4) in circumferential direction of the form, the web members engaging over the form plate edges at the rear sides thereof. The web members have a support (15,16) on the surface facing the structure in the region between the side edges of the spaced-apart form plates (3,4). The thickness of the support (15,16) corresponds approximately to the thickness of the form plates (3,4).
Abstract:
A form panel for a round form comprises a form skin, on a backside of which vertically extending profile rails are disposed, with which horizontally extending curved shaping bars are detachably connected. The shaping bars are each formed by at least two, preferably at least four, cast elements, each of which extends over a large portion of a longitudinal extent of the shaping bars and which are held together by shoes, and, due to a curvature-dependent offset between the cast elements in a longitudinal direction of the shaping bars in each instance at least one, preferably at least two, of the cast elements extend up to a particular front-side end of the shaping bars.

A formwork element of a round formwork comprises a form skin (1), on the backside of which vertically extending profile rails (3, 4) are disposed, with which horizontally extending curved shaping bars (13) are detachably connected. The shaping bars (13) are each formed by at least two, preferably at least four, cast elements (14), each of which extends over a large portion of the longitudinal extent of the shaping bar (13), and which are held together by shoes (15), and, due to a curvature-dependent offset (v) between the cast elements (14) in the longitudinal direction of the shaping bar (13) in each instance at least one, preferably at least two, of the cast elements (14) extend up to the particular front-side end (16, 17) of the shaping bar (13).
