Abstract
Disclosed is a method for producing a plate, wherein liquid, ultra-high-strength concrete is introduced into a formwork, which delimits a cavity, the cavity consisting of a first, flat region and a second, flat region adjoining the first region, the first and second regions having the same depth and being inclined with respect to one another at a bend angle of 120° to 170°. The concrete is introduced, in particular pumped, into the formwork from the bottom, rises in the formwork and hardens in the formwork in the shape of a bent plate.

Method for producing a plate (1) by liquid, ultra-high-strength concrete being introduced into a formwork (10), which delimits a cavity (18), wherein the cavity (18) consists of a first flat region and an adjoining second flat region, which have the same depth and which are inclined with respect to one another at a bend angle (α) of 120° to 170°, wherein the concrete is introduced from below into the formwork (10), rises in the formwork (10), and cures in the formwork (10) in the form of a bent plate (1).
Formwork (10) for producing a plate (1) from ultra-high-strength concrete, wherein the formwork (10) has a first formwork part (11) and a second formwork part (17) in each case with a fixed part (12, 12′) and a wing part (13, 13′) that is arranged to pivot on the fixed part (12, 12′) via a hinge (14, 14′), wherein the fixed parts (12, 12′) of the formwork parts (11, 17) are arranged parallel to one another, and the wing parts (13, 13′) of the formwork parts (11, 17) are arranged parallel to one another, wherein strip-like formwork elements (16) are arranged between the formwork parts (11, 17), and wherein a cavity (18) with an essentially uniform depth is delimited by the formwork parts (11, 17) and the formwork elements (16), wherein in a lower region, the cavity (18) has a fill opening (22) for concrete, for filling the cavity (18) from below, and wherein the wing parts (13, 13′) can be attached to the fixed parts (12, 12′) inclined at a bend angle (α) of 120° to 170°.
Plate (1) that consists of ultra-high-strength concrete, wherein the plate (1) has a first essentially flat section (2) and a second essentially flat section (3), wherein the plate (1) has an essentially uniform thickness (d), and wherein the plate (1) has at least three corners (5), wherein the first section (2) and the second section (3) are inclined with respect to one another at a bend angle (α) of 120° to 170°, so that the plate (1) has a bend (4) that runs essentially straight.
