Definitions
- the invention relates to a formwork element for the sheath concrete construction with side parts which are connected to one another by spacers.
- Large-sized formwork elements are known from DE-B-2 618 125 and can be used in a variety of ways, including in composite form, and enable cost-saving and fast construction with good external and internal thermal insulation.
- the connecting webs are in the form of metal grids or sheets during the connecting webs
- Anchoring ends relatively close to the outer surface.
- DE-U 7 625 460 describes a production element with at least two parallel plates in which the plates are connected by webs with plate-like extensions by gluing to the inside of the plates.
- the webs are made of steel and are glued to the plates in a dimensionally stable manner, the attachment of the webs being relatively complex and having to be carried out under controlled conditions.
- the invention is therefore based on the object to provide formwork elements for the sheath-concrete construction that take up little transport and storage space.
- a formwork element for the sheath concrete construction with two opposite side parts which are connected to one another by spacers which is characterized in that the spacers comprise at least two parts which can be pushed into one another, one part penetrating a side part and being connected to it, and each other part penetrates a second side part and is connected to it and the two parts of the spacer between the two side parts are pushed together and connected to one another in a tensile manner, whereby the two opposite side parts are connected to one another.
- Side parts are preferably placed on site, adapted to the conditions, one on top of the other and the two head parts of the spacers are pushed through the side parts and pushed into one another.
- Part of the spacers is usually so long that, when the two side parts lie on top of one another, it pierces the two side parts. This of course makes it very easy to attach the other part of the spacer.
- the two spaced side panels are then pushed apart and raised.
- the formwork elements can only be cut to size after assembly.
- the side panels can be cut according to your needs.
- the spacers are preferably provided at their two ends with a plate-shaped thickening to prevent the spacers from slipping through the side parts during the filling of the formwork elements with concrete.
- the spacers have a shape optimized for tensile stress in their part pushed into one another. For this you can, for example, provide a part with barbs which engage in grooves or dents on the other part.
- the two parts pushed into one another can also be connected to one another in a tensile manner with an adhesive.
- the tensile connection can thus be achieved mechanically and / or by adhesion.
- the spacers can, in the immediate vicinity of their two ends, be provided with barbs which engage in the side parts and thus prevent the side parts from collapsing unintentionally. Additionally or alternatively, at least individual spacers on the inside of the side parts can be provided with a disc which prevents the side parts from collapsing unintentionally.
- coaxial bores are provided in the spacer from its two ends. Pins can then be introduced into these bores, which connect formwork elements standing next to one another or one above the other. After the concrete has hardened, these pins can be removed and used again.
- the spacers contain plastic as possible, such as. B. polypropylene or polyamide. Since the spacers are relatively thin, there is no risk that in the event of a fire, the flames break through the walls. However, they can also contain metal, for example sheet metal or stainless steel. Because of the small diameter of the spacers, there is no risk of cold bridges forming.
- the side parts preferably contain an insulating material made of plastic,
- the side parts can also contain depressions on their outer sides for the thickening at the ends of the spacers so that a flat outer surface is created.
- edges of the side parts can be provided with dovetail, rebate or groove and tongue-like profiles to avoid the formation of continuous butt joints.
- they can be provided on their inner and / or outer surfaces with a surface structure such as Grooves, knobs or similar be provided.
- FIG. 1 shows a section through a formwork element according to the invention
- FIG. 2 shows another embodiment of a formwork element
- FIG. 3 shows another embodiment of a spacer
- FIG. 1 shows a formwork element 10 according to the invention with two side parts 12, 14 which are connected to one another by a spacer 16.
- the spacer 16 essentially consists of two telescoping parts 18, 20 which are pierced from the outside through one of the side walls 12, 14 and then connected to one another in a tensile manner between the side parts 12, 14.
- the tensile connection is achieved in that the two parts 18, 20 into one another be pushed and then click into place. In this example, this is done by barbs 22 which are attached to the part 18 which is inserted into the second part 20. These barbs 22 engage in special recesses 24 on part 20 and connect the two parts 18, 20 of the spacer 16 to one another in a tensile manner.
- the two parts 18, 20 of the spacer have plate-shaped widenings 22 at one of their ends, which prevent the spacer 16 from slipping through the side parts 12, 14. This is particularly important when filling the formwork element 10 with concrete.
- the number of spacers per square meter naturally depends on the pressure to be expected. So you can provide a higher number of spacers in the lower part of the wall, where the expected pressure when filling with concrete is greatest than z. B. near the ceiling.
- the two parts 18, 20 of the spacer 16 are provided in the vicinity of their respective head parts with barbs 26 which engage in the side parts 12, 14 and thus prevent them from collapsing unintentionally.
- the spacer 16 is provided with a circumferential notch 28 which allows iron bars 30 to be laid quickly and precisely for the reinforcement of the concrete. This notch 28 also prevents the iron bars from slipping while the formwork elements are being filled with concrete.
- the spacers 16 have coaxial bores from their two ends
- FIG. 2 shows a formwork element 10 'which differs from that on the
- FIG. 1 illustrated element differs by a different design of the spacer.
- the spacer 16 ' is provided with a locking disk 32 on the inner side of a side part. This locking disk makes it easier to push the side parts 12, 14 together.
- FIG. 3 shows another embodiment of the spacers 16 ". For the sake of simplicity, the side parts are not shown.
- the parts of the spacers 16" pushed into one another have a tensile force optimized shape.
- a plurality of small circumferential teeth 34 which are attached to one part of the spacer 16 "engage in a relief structure 36 which are attached within the other part of the spacer 16".
