Description

[0001] The invention relates to an alignment device for double walls.

[0002] Today, individually prefabricated concrete shells are used to erect concrete shear walls. These are narrow concrete walls connected by lattice girders. These form a kind of formwork, similar to that created with conventional wooden formwork elements. The shells contain all the reinforcement, for example. The structure serves as a solid formwork for the fill concrete to be poured. These concrete walls form a space that can be filled with liquid concrete. One problem is aligning the precast concrete walls, i.e. the double walls standing next to each other, so that these precast concrete walls are in line with each other, thus forming a non-curved overall wall. Up to now, this has been achieved using shims, squared timber and diagonal bracing, i.e. diagonal supports, which are placed to align the precast concrete walls.

[0003] Typical dimensions for double walls are heights up to 3 m and lengths up to 7 m, or heights up to 7 m and lengths up to 3 m. Lengths up to 14 m are possible. The usual wall thicknesses are 18, 20, 24, 25, 30, 36, 40, and 42 cm. The usual shell thicknesses are 4.5 to 7.5 cm. Typical dimensions are heights up to 3 m and lengths up to 7 m, or heights up to 7 m and lengths up to 3 m. Lengths up to 14 m are possible. The usual wall thicknesses are 18, 20, 24, 25, 30, 36, 40, and 42 cm.

[0004] The object of the invention is to improve the state of the art and in particular to provide a device which enables formwork elements such as precast concrete walls to be aligned in such a way that a non-curved concrete wall is created.

[0005] The problem is solved by the claims.

[0006] The subject of the invention is an alignment device which comprises an elongated flat iron with a plurality of adjustment openings, which has at one end a non-displaceable, preferably rectangular locking plate which is arranged centrally at a right angle to the elongated flat iron, and a further locking plate which is arranged displaceably in the center of the flat iron and a wedge-shaped locking flat iron which is a fit for the adjustment openings, wherein the centrally displaceable locking plate is displaceable along the edges and surfaces of the flat iron.

[0007] The alignment device comprises an elongated flat bar with multiple adjustment openings, which has a fixed rectangular locking plate at one end, while the opposite end is freely accessible, i.e., an object such as another locking plate, which has a matching slotted hole in the circumference of the elongated flat bar, can be pushed onto it. The elongated flat bar preferably has a length (X-axis) to width (Y-axis) ratio of 10 to 1. For example, preferably a length (X-axis) of 45-50 cm and a width (Y-axis) of 4-5 cm and a depth of 6 mm.

[0008] The elongated flat bar has a rectangular, non-adjustable locking plate at one end, which is arranged centrally at a right angle to the elongated flat bar. It also has another locking plate, preferably of the same size—i.e., of the same area, circumference, and edge dimensions—with a centrally located elongated hole, allowing it to be moved centrally on the flat bar via its centrally located elongated hole. The adjustable locking plate preferably has a size of, for example, 50 mm long x 8 mm wide x 6 mm deep.

[0009] Thus, the centrally displaceable locking plate (this preferably has a size of, for example, preferably 100 mm length x 100 mm width x 6 mm depth) has an elongated hole in its center, for example preferably 50 mm length x 9 mm width x 6 mm depth, with which the displaceable locking plate can be arranged on the flat iron in a form-fitting manner, wherein the displaceable locking plate is displaceable along the two edges and surfaces of the flat iron and the two surfaces of the displaceable locking plate over the two surfaces of the elongated flat iron are preferably larger than the two surfaces over the edges of the flat iron.

[0010] The adjustment openings, in the form of elongated holes, are arranged on the elongated flat irons parallel to the length of the flat iron, i.e., along the X-axis. Preferably, there are several adjustment openings arranged one behind the other and offset from one another. The number of adjustment openings can be 1, 2, 3, 4, 5, 6, 7, 8, 9, 10, etc. The elongated holes preferably have a size of, for example, 35 mm long x 9 mm wide x 6 mm deep.

[0011] The alignment device comprises a wedge-shaped locking flat bar that fits the adjustment openings, allowing the centrally movable locking plate to be secured. The locking plate can be moved along the edges and surfaces of the flat bar. The wedge-shaped flat bar is preferably 25 to 30 mm long x 10 mm to 45 mm wide x 6 mm deep, with the width tapering evenly from the widest part to the narrowest part, i.e., from 45 mm to 10 mm. The wedge-shaped locking flat bar is preferably connected to the centrally movable locking plate via a chain.

[0012] The alignment device according to the invention is preferably made of metal, such as steel or stainless steel.

[0013] The alignment device according to the invention is arranged in the narrow joint formed by the narrow sides of two adjacent double walls, with its perpendicular broad side (Y-axis) of the flat iron, i.e. so that the larger surface area of ​​the elongated flat iron runs parallel to the narrow sides of the two double walls, wherein the non-displaceable rectangular locking plate is arranged on one side of the double wall and the displaceable rectangular locking plate is arranged on the opposite side of the double wall and the locking plates are fixed in place by the wedge-shaped locking flat iron is fixed in the nearest suitable elongated hole in the elongated flat iron of the alignment device, so that the two double walls lying next to each other with their narrow sides can be aligned in a straight line.

[0016] Fig.Figure 3 shows the adjustable locking plate 5 in its flat configuration with the central elongated hole 8, as well as the wedge-shaped locking flat bar 6, which fits the adjustment openings, with the width tapering evenly from the widest part to the narrowest part. The wedge-shaped locking flat bar 6 is preferably connected to the centrally movable locking plate 5 via a chain 7.
