DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a formwork apparatus for shell concrete masonry.

[0002]

2. Description of the Prior Art In such a formwork device, for example, from Austrian Patent 186,397, at least two dams of different heights are arranged parallel to one another at a distance from each other (and vertically). And are held together by one or more separators in the form of wire bands. The separator has two abdominal portions at one end, with which the separator is mounted on the upper ridge of one of the dams.

[0003] The opposite end is provided with only one flank (at a distance from the free end), and the separator is provided at the opposite end on the opposite weir plate and the flank on the inner surface of the weir plate. It is inserted until it abuts. Next, the protruding end of the wire band is bent at the outer surface of the weir plate.

[0004] Depending on the material and thickness of the weir plate, it is difficult or impossible to insert the separator through the weir plate. In any case, this is associated with considerable power and time expenditure. Furthermore, the insertion can be realized virtually only with the plate sideways, with the attendant disadvantage that the insertion point is strictly pre-determined so that the separator can be subsequently mounted in the desired position on the opposite weir plate. It must be marked.

[0005] Finally, bending of the wire ends can lead to damage or destruction of the plate, depending on the material of the plate. Unless the folded part is successfully placed on the outer wall of the formwork, precise positioning is impossible.

[0006] A separator made of wire, known from Austrian Patent 218 228, comprises:
Vertical wire pairs abutting the inner and outer surfaces of the weir plate, respectively, are provided at the ends of the separator. The distance between the wire pairs is selected according to the thickness of the weir plate so as to enable fixing without play. Austrian Patent No. 21822
According to the specification No. 8, separators are mounted on the upper ridges of opposite plates of identical construction on both sides. Therefore, the fixing between the weir plate and the separator is performed only on the edge side. For larger formwork heights, this device is not applicable because the pressure of the concrete will result in bulging or breakage of the dam.

[0007]

SUMMARY OF THE INVENTION An object of the present invention is to provide an outer shell concrete so as to facilitate the stacking of the weir plates and to ensure sufficient stability of the formwork even when the structural height is increased.

On the premise of the prior art according to Austria Patent 186,397, the idea of the invention consists in constructing a weir plate with one or more slotted openings, so that the existing holes are prepared. With this hole, the corresponding separator can be easily inserted without applying force, and can be locked with the weir plate. In particular, as will be clear from the following description of the associated separator according to the invention, it is advantageous if the slot-like opening (s) extend parallel to the outer ridge of the horizontally extending weir plate at the mounting position. It is.

[0015] However any other alignment of the slot-like opening are also possible, for example, it is possible to extend perpendicularly to the outer edges of the sheathing board extending horizontally in the assembly position. The slotted opening should have a cross-sectional area slightly larger than the outer dimension of the corresponding end of the separator, so that the separator can be easily and easily introduced into the associated slotted opening Will.

The opening in the weir plate arrangement depends on the geometric conditions of each case. When one of the barrier plates on which the separator is mounted has exactly half the height of the opposite barrier plate through which the separator is inserted, the opening is provided at exactly half the height of the barrier plate. Become. Depending on the length of the weir plate, two, three or more openings are respectively provided at intervals from one another. Although not required, the present invention includes slotted openings in all plates, for example, as long as additional separators are desired to further stiffen the formwork apparatus.

According to one embodiment, the sheathing board consists of wood wool insulation panels, including multi-layer board. In an embodiment included in the formwork apparatus according to the present invention, in addition to the weir plate, the separator comprises a rod-shaped base, and two abdominal parts are provided at both ends of the base at intervals from each other. Are provided, and the abdomen protrudes from the base perpendicularly to the base on opposite sides, respectively, and the distance between the abdomen on the distal side is
(At the point of attachment to the base), equal to or greater than the thickness of the corresponding weir plate, and at least in one part less.

[0018] The embodiment of the separator is similar to that described in Austrian co Toshikuni Patent No. 218,228. However, in an advantageous development of this prior art, the centering and the original stress between the separator and the plate are achieved, for example, by the curved contours of the two middle abdomen, and the thickness tolerance of the weir plate can be compensated without problems. it can. This means that the minimum distance between the corresponding distal abdominal parts is smaller than the thickness of the associated weir plate.

The original stress of the relevant abdomen (balance) may proceed enough to be the same separator is also used to secure the different sheathing board thicknesses.

According to one embodiment, only the free end extent of the corresponding abdominal is bent. Selectively or simultaneously,
The free ends of the respective outer abdomen (bars) can also be configured to be bent outward, in which case the bent parts face away from the respective abdomen.

[0021] In accordance with this embodiment of the separator, assembling is facilitated, which is still fully described among the following drawing description. The separator preferably comprises a metal, for example a metal wire.

[0022] with at mold apparatus according to the invention, simple as compared to known mold apparatus, but effective improvement is achieved. The stacking of the forms can be performed more quickly without damaging the dam plate. The stability between corresponding dams is increased. This makes it possible to construct a formwork wall having a large area in which concrete can be poured in one step.

Further features of the invention will become apparent from the features of the dependent claims and other application documents.

DESCRIPTION OF THE PREFERRED EMBODIMENTS Hereinafter, the present invention will be described in detail based on one embodiment. According to FIG. 1, a first weir plate 10 and a second weir plate 12 are arranged on a ground 14 in a known manner at a distance A parallel to each other. Both weir plates 10, 12 are wood wool insulation plates. It can be seen that weir plate 12 is twice as high as weir plate 10.

The weir plate 12 has three slot-like openings (longitudinal slots) 16 at half height. A total of three separators 18 of the type shown in FIG. 4 are provided in order to fix the dams 10 and 12 to each other and to limit the spacing A for further stacking of the formwork devices. Each separator has a rod-shaped base 20.
Consists of Two abdominal parts 2 in both end ranges 20a, b
2a, 22b are spaced apart from each other, and the abdomen extends substantially perpendicular to the base 20, and
0 is welded.

As shown in FIG . 4, the abdomen 22a and 22b extend on both sides of the base 20. Each outer abdomen 22
a has a substantially linear shape. Only its free end 22a 'is bent outward (away from the corresponding abdomen 22b). The abdomen 22b has a curved profile. Joining points 22c, 22 of two adjacent abdomen 22a, 22b
The interval between c ′ is slightly larger than the thickness D of the weir plates 10 and 12. The distance between the two connection points 22c 'is equal to the distance A between the dam plates 10 and 12.

The two legs 22b of the abdomen 22b ', 22
Starting from the junction 22c ', b "extends in the direction of the abdomen 22a corresponding to the curved contour and then in the opposite direction after the curved portion.

[0028] After assembly of the mold apparatus of the first group, the separator 18 is inserted into a corresponding groove hole-shaped openings 16 respectively 90 ° turned position relative shown that shown in FIG. The length of the slot 16 is greater than the length of the abdomen 22a, but smaller than the length of the abdomen 22b. Therefore, the separator 18
When the abdomen 22a is inserted, the abdomen 22a
2b is inserted until it contacts the inner surface of the weir plate 12. Lightly pressurized, the separator 18 is further passed through the weir plate 12, whereby the separator 18 is pushed back until the spring arms 22b ', 22b "and the abdomen 22a of the abdomen 22b completely pass through the opening 16. At this moment, the separator 18 is removed. The separator 18 is surely brought into contact with both outer surfaces of the weir plate 12 based on the spring action of the abdomen 22b by being turned about 90 ° to the position shown in FIG.

[0029] simultaneously separator 18 is rotated, abdominal 22a at the opposite end of the separator, 22b is mounted on the right side of the sheathing board 10 in FIG. 1, against the sheathing board 10 is the bottom respectively, the sheathing board 12 The fixing is carried out in the same manner as described above based on the fixing of the separator 18 in the above. The folded end 22a 'facilitates insertion.

In order to facilitate the rotation of the separator 18 as a whole, as shown in FIG.
Another lateral abdomen 26 can be provided between b to serve as an operating abdomen. After all three separators 18 are assembled between the dam plates 10 and 12, another dam plate 12 'is mounted on the dam plate 10. This is the abdomen 22a, 22b
By simply fitting between the portions that are free to project upwards, respectively.

The weir plate 12 'has the same size as the weir plate 12 and also has three slot-like openings 16. The fixing of the weir plate 12 'to the weir plate 12 is performed in the same manner as the fixing between the weir plates 10 and 12, as described above. Obviously, a form body of almost any size can be achieved, in which concrete is subsequently poured.
