Description

The present invention relates to a formwork element according to the preamble of claim 1.

From the Scriptures DE 10 2006 029 697 It is known to provide a reinforcing cage in a formwork element, which serves the purpose of reinforcing the filled in the formwork space filler after curing against acting mechanical loads, as is common for example in concrete through steel reinforcement reinforcement. Since the prefabricated formwork elements always have only a comparatively short length and thus several formwork elements must be strung together to produce a ring beam or a fall over a wall opening in a desired length, arise at the joints between two adjacent formwork elements interruptions in the reinforcement , which form a kind of predetermined breaking point at later mechanical loads because of the lack of reinforcement at the joints.

To bridge the joints with reinforcing elements, is in the Scriptures DE 10 2006 029 697 proposed to insert bar steels in the formwork space, which are so long and positioned so that they bridge the joints after the positioning of the formwork elements in the shell installation position. In order to insert the steel bars, the reinforcement cage should be formed of G-shaped wire elements.

In practice, it has been found that the production of reinforcement cages with a G-shaped cross-section is quite expensive. Also, the transport and handling are not facilitated by the size of the reinforcement cages. The spaced apart in a formwork element arranged G-shaped brackets are already connected to each other by some bar steels, which are distributed over the cross section of the formwork element attached. These steel bars make the formwork elements very heavy, the still manageable length of the formwork elements This is considerably restricted. Finally, it is more or less left to chance where the inserted steel bars come to rest within the reinforcement cage. In any case, the bar steels are always at the bottom of the reinforcing cage due to gravity; such a situation does not always correspond to the statically desired and presupposed position. It is completely unclear at what point, as seen across the width of the reinforcement cage, that the subsequently inserted bar steels come to rest. The position of the steel bars can also move during concreting. A predicted statics for the component to be created can not be maintained in this way.

From the Scriptures US 2002/134040 A1 is a generic formwork element known. Beyond a formation in the connecting elements, no means are disclosed there, as the bar steels arranged in the lower region of the cross section are better positionally fixable and also make it possible to arrange additional bar steels in the upper cross-sectional area. The same applies to the writings EP 0 692 585 A1 and FR 2 881 423 A1 ,

The font US 2005/023432 also discloses a generic formwork element according to the preamble of claim 1.

It is the object of the present invention, as far as possible to overcome the disadvantages described above and to find another technical solution for the joints of formwork elements bridging reinforcement.

The object is achieved by a generic formwork element by the characterizing features of claim 1.

The assembly of a ring formwork on a construction site is substantially facilitated by the formwork elements designed according to the invention. The formwork elements initially consist only of the formwork panels and the connecting elements and are therefore not yet weighted by additional reinforcing elements. The formwork elements can be easily spent to their installation site and there are conventionally attached, and the attachment is not hindered by disturbing components of the reinforcement. Then the bar steels can be inserted from above into the formwork elements which are lined up in their installation position. Since the cross-section of the formwork elements is limited only by the connecting elements, remains a readily accessible from above formwork space in which the bar steels only need to be stored, for example with the aid of a crane. Heavy physical work no longer needs to be done by the construction workers to place the bar stock in the formwork space.

The processing of bar steels is simple and efficient, as previously no reinforcing baskets had to be bent and braided for the reinforcement in the formwork elements. The production of G-shaped connector deleted. Apart from the assembly of the lightweight formwork elements no preparatory work must be done to produce a reinforcement for the formwork elements. It is sufficient to insert the rod material in the formwork elements and cut the rods fitting.

By using the fasteners as supports, the bar steels can be easily positioned and aligned in the transverse direction, since the support surface on which the bar steels rest and slide, and thus the frictional resistance against lateral displacement is reduced. As a further advantage, the bar steels are forcibly held by the supports in a standard minimum distance from the downwardly facing outer surface of the formwork component, without the need for additional alignment work would occur. The fasteners may additionally have lateral stops that protrude so far from the inner surfaces of the side shuttering panels inward, that by them, the compliance of the standard minimum distances to the inner surfaces of the side shuttering panels is forcibly specified. In this way, the bar steels resting on the connecting elements are positioned so far inside the cross-section of the component that any moisture present from the outside can not reach the bar steels and cause corrosion on the bar steels. For a sufficient concrete cover is taken care of.

After inserting in the lower region of the cross section of the formwork element to be arranged bar steels can now wireforms within the cross section be attached to the formwork element, can be placed on the above the lower portion of the cross section to be arranged bar steel as reinforcing elements. The wireforms are easy to install, according to one embodiment of the invention, a simple insertion of the wireforms in the interior of the formwork elements is sufficient. For a complete ring anchor of an average residential building this work is done in a few minutes.

On the wireforms can then also from above - again with the aid of a crane, if any - the steel rods to be incorporated above the arranged in the lower region of the cross section steel bars in the formwork cross section as reinforcing elements in the juxtaposed formwork elements are inserted. The same advantages as described above for the bar steels to be placed on the connecting elements apply to the overlaying of the further bar steels on the wireforms. The multiple insertion of bar steels with an interposed to be carried out the wire structure in the cross section of the formwork elements is faster and easier to do than the complex bending, positioning and fixing of reinforcing baskets.

The amount of built-in finished finished component iron and steel can be reduced by the invention, since material for the reinforcing elements is installed only in the loading direction in the formwork elements, the bars used as reinforcing elements can be specified precise load and beyond only small amounts of material the spatial positioning of the bar steels are used.

As a result of the wireforms, the bar steels arranged in the lower region of the cross section are kept spatially separated from the bar steels to be positioned above them. The bar steels can thus be positioned distributed at predetermined heights over the cross section of the formwork element. Compliance with a given statics is so much easier and safer. It can also be specified by the static rod steel with diameters and tensile strengths, by the compliance with the static requirements in by the use of fasteners and the wireform is ensured predetermined installation positions within the cross section of a formwork element.

An inventive wire structure is designed two-dimensionally as a wire deformed in a plane. The wireform is thus very flat and light and yet has sufficient strength to hold the reinforcing elements in a desired position. To be able to carry heavier reinforcing elements, it is sufficient to insert the wire elements at shorter intervals in a formwork element. For lighter reinforcement elements, the distances at which the wireforms are positioned in the formwork element can be increased. Elaborate reinforcement baskets, which are expensive to produce and bulky in storage, transport and processing, can be dispensed with. By the subsequent connection of the wireforms with the formwork elements previously inserted reinforcement elements can be fixed in position, if the wireforms have a correspondingly suitable shape. After assembly of the wireforms, further reinforcement elements can then be placed on or next to the wireforms if required.

The shape of a wireform may be designed such that the shape of the wireform partially surrounds one or more reinforcing elements. The formation can engage under the reinforcement element, so that it is supported by the wireform, or the wireform is shaped so that it laterally supports a reinforcing element, so that it is no longer displaceable in its installed position over the width of the formwork element, without the wireforms deform, or the wireform overlaps with its shape one or more reinforcing elements, which are also not displaced by it in the lateral direction.

The formation need not be designed so that inevitably results in a jamming or positively locked seat of the reinforcing element in the wireform, the formation may allow lateral play between the wireform and the reinforcing element, which is dimensioned so that at least one gives approximately certain mounting position for the reinforcing element, resulting in any case by the game-related variations in the spatial position of the reinforcing element no significant influences on the calculated static of the component to be produced with the formwork elements. By a certain play the manufacturing process of the formwork is simplified and accelerated, since the reinforcing elements are easier to bring into their nominal position. The fixation must at least be such that an unwanted displacement of the reinforcing element from its desired position out is so far complicated that it no longer comes to a shift in light impulses in a conventional subsequent concrete pouring and compaction.

The attachment of the wireform in the formwork space can be done in different ways. Thus, it is conceivable to make the wireform so that there is a jamming system of the lateral legs of the wireform on the inner surfaces of the formwork panels. In this case, a simple insertion of the wireform in the formwork space is sufficient. However, it can also be additionally or alternatively provided separate receiving elements, via which the wireform is connectable to the formwork element in order to support it so that a sufficiently stable arrangement results to accommodate the reinforcing elements and to keep sufficiently accurately positioned. Here, for example, perforated anchor strips come into consideration, which are glued to the inner surface of the formwork panels and in the holes, the ends of the wireforms can be inserted for attachment.

The wire structure has at its in the installed position downwardly facing underside and / or at the lower halves of the legs in each case at least one shape. Through these positions of the molding, it is possible to keep one or more reinforcing elements in a desired position in the lower region of a formwork element.

The wireform is designed as a bracket, which is open in the installed position down and in which a connecting the two lateral legs upper crosshead over the two lateral legs are supported downwards. Such a bracket is very easy and inexpensive to produce from a single workpiece such as a wire section or a sheet. The workpiece can be bent accordingly in a desired shape. Static results in a stable construction. The traverse can be used as a support for reinforcing elements. The weight of the resting on the cross member reinforcing element can then be derived via the side legs down. Due to the derivative downwards, the connection of the wireform to the formwork element does not necessarily have to be loaded, which can have a destabilizing effect. The shape of the bracket can be designed so that the weight of a resting reinforcing element intensifies the connection of the wireform with the formwork element. This can be done, for example, by the reinforcement element receiving formation is formed inwardly offset to the lateral legs on the crossbar. Due to the ballast from the reinforcing element of the leg is slightly spread laterally, whereby the contact pressure with which a leg rests on the adjacent wall of a formwork panel increases. The increased contact force improves the frictional engagement between the leg and the shuttering panel, so that it is held firmly fixed. The stirrups are easy to store, transport, handle and process. The bottom open design material is saved for the wireframe that is not needed for the function.

The wireform has a geometrically suitable shape with which it can be positively and / or non-positively connected to a connecting element. Since the fasteners are already structurally designed so that they absorb the bending forces acting on a filled formwork, they are designed very stable. Often, the profiles used for the fasteners have a U-shaped cross-section, which results in a better support against the bending forces. In this U-shaped cross-section of a connecting element, the wireforms can be adjusted well. The connecting elements may alternatively or additionally have holes or notches with or without holes into which the ends of a wire structure can be inserted. The holes or notches then form a receptacle in which the wireforms are held positively. The wireforms can also be based on a surface of an associated connection element. Even a slightly jamming non-positive contact with a connecting element may be sufficient to connect a wire structure sufficiently firmly with a formwork element. By the construction and / or investment of one or more reinforcing elements results in a subsequent connection of several wireforms with each other, which support each other. The wireforms need only be sufficiently firmly positioned to hold the reinforcing elements in the installation position during the casting of the filling compound. After casting, the filler hardens, and the static functions are completely or at least predominantly met by the reinforcing elements, this is the wireforms are not required.

According to one embodiment of the invention, the wireform has at least one shape on the upper side facing upwards in the installed position. With one or more protrusions on the top, they are particularly accessible from above. It is easy to initially place reinforcing elements only on the wireform and then bring the reinforcing elements in the desired position in the molding. In the desired position on the upward-facing upper side of the wire structure, the reinforcing elements are held in a raised and spaced from the bottom of the formwork element level. The reinforcing elements can be held in this way positionally accurate in an upper region of the formwork element, in which it was previously hardly possible without a special reinforcing cage, vorzuhalten reinforcing elements accurately.

According to one embodiment of the invention, the wireform is connectable with separate connectors with the formwork panels, the connecting element and / or other ground. In order to increase the strength of the connection of the wireforms with the formwork panels, the associated connecting element or any other substrate, these can of course be stabilized by additional measures or means, such as by welding or adhesive dots, adhesive tape, Cable ties, wire ties or the like or by dowels, clamping screws, staples, gag, rivets or the like.

According to one embodiment of the invention, formations are arranged so that there is a molding in each quadrant of an end view of the formwork element. In an example, rectangular cross-section of the component to be produced with the formwork element reinforcing elements can be arranged in each quadrant of the component, resulting in a particularly favorable statics.

According to one embodiment of the invention, the wireform is made of a metal wire. Metal wire is inexpensive to procure, easy to process, can still be adapted on site by bending to certain geometries and has a thermal expansion coefficient that is very similar to that of concrete. But it is also possible to use a plastic material as the wire structure, if necessary, fiber-reinforced.

According to one embodiment of the invention, one or more brackets are placed on the reinforcing elements resting on the wire structure, which engage over the reinforcing elements from above, wherein the lateral limbs of the or the bracket are designed so long that they are in the vertical direction with the fasteners and / or overlap the wireform. The steel bars used as reinforcing elements serve to absorb the tensile and compressive stresses acting on the finished component. To accommodate the shear stresses strapping of the reinforcing elements is required in addition. The strapping does not have to be firmly connected to the reinforcement; it is sufficient if strapping is available at all. The strapping does not have to surround the reinforcement in a closed piece, the strapping can also be designed in several parts, if the legs of the strapping forming parts overlap at least partially. The brackets can be made of a wire or flat sheet metal. An adjacent arrangement of the overlapping, forming a strapping components is advantageous in which the distance between the overlapping components in the overlapping region should not be more than 5 cm apart. Since the formwork elements are best accessible from above because of the laterally arranged formwork panels, it is advantageous to provide the overlap in the vertical direction, since then a bracket can be lowered from above simply in the cross section of the formwork element and stored on the bar steels.

According to one embodiment of the invention, one or more brackets are placed in a section between two adjacent connecting elements on the reinforcing elements and the lateral limbs of the bracket or overlap with brackets, which are also arranged in the section between two adjacent connecting elements and the reinforcing elements from below embrace. Depending on the static requirements, it may be necessary to arrange the brackets not only in the region of the connecting elements, but also at shorter distances from each other between two adjacent connecting elements, for example in the region of supports under the component to be shed. In order to use uniform formwork elements for the formwork, it is proposed to form a strapping of brackets in a section between two connecting elements, one of which surrounds the reinforcement elements from below and another bracket, the reinforcing elements from above. The below the reinforcing elements embracing bracket may have been inserted before inserting the steel bars in the formwork space, but it may also have been then brought into its installed position. The overarching bracket is attached after inserting the steel bars on this.

According to one embodiment of the invention, the bracket of a wire, which is bent into a spatial shape, which surrounds the reinforcing elements from the outside. For example, cube, cuboid, triangles or the like come into consideration as spatial form, the legs of which form a U-shape which is open from one side. Due to the spatial form, the stirrups can stand in the formwork space without further attachment.

According to one embodiment of the invention, the one or more brackets are made of a wire or a flat material and have a ribbed surface and / or at the ends of a hook-like section. Due to the ribbed surface and / or the hook-like sections, the straps are positively connected to the surrounding filling material such as concrete and can absorb much higher forces from the concrete than would be possible with smooth surfaces and without hooks.

It is expressly understood that the above-described respective embodiments of the invention can be combined individually and in any combination with each other with the subject of the invention according to the features of the main claim.

In Fig. 1 is a view of an inventive formwork element 2 shown from the front side. In the front view, the two side shuttering panels 4 can be seen, which by a U-shaped bracket as a connecting element 6 with each other are connected. In the exemplary embodiment, the connecting element 6 is made of U-shaped profiles, but it can also be used iron flat iron. For the invention, it is also irrelevant whether the connecting element 6 is arranged in the lower, middle and / or upper region of the formwork element 2. The formwork panels 4 define between them the formwork space 8, which is filled with a filling material such as concrete to the upper edge of the formwork panels 4. The formwork element 2 can be placed on a wall ring or the like, said in Fig. 1 not shown. At the in Fig. 1 shown embodiment, the formwork element 2 only two side shuttering panels 4, for casting falls but also shuttering elements 2 can be used, which also have on your bottom another third shuttering panel 4 and are closed in this way down. Such formwork elements 2 can also be equipped according to the invention.

In Fig. 1 are in the formwork space 8 a total of 4 reinforcing elements 10 inserted. Two reinforcing elements 10 are located in the lower region of the formwork element 2 and two reinforcing elements 10 are located in the upper region of the formwork element 2. The two arranged in the lower region reinforcing elements 10 are placed on the inwardly upstanding legs of the connecting element 6. As a result, the lower reinforcing elements 10 are held at a sufficient distance from the underside of the formwork element 2. However, the connecting element 6 itself has no means to prevent unwanted lateral displacement of the lower reinforcing elements 10. When filling the shuttering space 8 with the filling compound, the lower reinforcing elements 10 can thus move freely in principle in the lateral direction, if they were not fixed by the wireform 12 in a desired position. The wireform 12 has special formations 14, through which the reinforcing elements 10 can be fixed in a desired position. In the lower region of the formwork element 2 and the wire structure 12, the formation 14 is designed as a kink, through which the wireform 12, the lower reinforcing elements 10 engages behind inside and in this way spatially close to the upwardly projecting legs of the connecting element 6 in the shown Fixed position fixed. The lower formations 14 of the wire structure 12 prevent the reinforcing elements 10 from slipping uncontrollably laterally on the connecting element 6. The lower wire ends of the wire structure 12 may be inserted into holes or notches of the connecting element 6, resulting in a positive locking of the wire ends.

In the upper region of the formwork element 2 and the wire structure 12, the formations 14 are formed as approximately semicircular troughs, in which the reinforcing elements 10 can be inserted. Since the shape of the troughs is at least approximately adapted to the shape of the reinforcing elements 10, these are also secured against lateral slippage when they are inserted into the upper formations 14. Notwithstanding the embodiment, more or less formations 14 may be provided on the wireform 12 and the formations 14 may be disposed at locations other than those shown in the embodiment.

In the exemplary embodiment 10 metallic bar steels are used as reinforcing elements. Of course, other elements suitable for reinforcement can also be used instead of such metal bar steels, such as, for example, reinforcing baskets or other material.

In the embodiment, the wireform 12 is designed so that it rises to near the upper edge of the formwork element 12. If the upper reinforcing elements 10 are to be positioned lower, it is also possible to provide the wireform 12 in a lower designed embodiment, or a plurality of wire elements 12 with different height dimensions are set in a formwork element 2.

If the reinforcing elements 10 are installed in the formwork element 2, it is possible initially to place the reinforcing elements 10 with a crane or manually on the top 16 of the wireforms 12. Thereafter, the reinforcing elements 10 can be manually inserted into the moldings 14 provided for this purpose become. The weight of the applied reinforcing elements 10 resting on the traverse 20 is supported by the legs 18 of the wireform 12. In this case, the wire of the wire structure 12 is dimensioned sufficiently strong to accommodate the weight of the reinforcing elements 10.

Since the bar steels of the reinforcing elements 10 extend beyond the joints of adjoining shuttering elements 2, the reinforcing elements stabilize the component produced with the shuttering elements 2 over the joints.

In the exemplary embodiment, the wireform 12 is inserted into the U-shaped profile of a connecting element 6. By a clamping engagement on the side surfaces of the connecting element 6, the wireform 12 is held in the position shown. Although within the U-profile, the wireform 12 may still tilt forward or backward by a few degrees, but since the wireform 12 strikes the upper edge of the profile limb, the wireform 12 can not fold away completely. Such a more or less loose attachment may be sufficient to fix reinforcing elements 10 sufficiently firmly in a desired position. If desired, however, additional measures can be taken to more strongly define a wireform 12 in an installed position.

In Fig. 2 a single wireform 12 is shown. At the top 16 is the traverse 20, which has the upper formations 14. Laterally, there are the legs 18, which have as a lower formations 14 a buckle in the legs 18. The wireform 12 may be made from a single piece of wire, with the wire being converted to produce the wireform 12 accordingly. The wireform 12 is a wire formed two-dimensionally in a plane, which is flat and takes up little space. The shape of the wire structure 12 is adapted in the embodiment to the internal dimensions of the associated formwork element 2.

If you divide the frontal cross-sectional area of the formwork element 2 in four equal quadrants, it will out Fig. 1 clearly that at least one reinforcing element 10 is arranged in each of the quadrants. Such a uniform distribution of the reinforcing elements 10 across the cross section of the component is possible with the wireforms 12 according to the invention in a simple and cost-effective manner.

In Fig. 3 is a view of a formwork element 2 with a in an anchor bar 22 and a plugged into a notch 24 wireforms 12 are shown. The anchor strip 22 is a perforated angle profile, which is glued to the inside of a shuttering panel 4, but can also be attached there in some other way. The anchor bar 22 may be arranged at any height, it may also be present several anchor bars 22. When the notches 24 are bent sheet metal pieces of the profile element 6, each with a punched hole, which have been swung out to the inside to insert the legs 18 of the wireforms 12 in the holes can. Again, the notches 24 may be made in a different from the embodiment shown number and height. Also in Fig. 3 Formations 14 shown are designed so that reinforcing elements 10 can be fixed sufficiently firmly against inadvertent displacement. By combining the fixation of the reinforcing elements 10 by an upper wire formation 12 in the anchor strips 22 and the lower wire formation 12 in the notches 24, the reinforcing elements 10 can again be well distributed over the cross-sectional area of a formwork element 2.

In Fig. 4 is a modification of the wireform 12 from Fig. 2 shown, in which the traverse 20 is designed so that it also serves as a holder for receiving a further component such as upwardly open C-profile 26, which is also known by the name Halfenprofil. The C-profile 26 is poured flush with its upper edge in the ceiling edge, which is particularly easy by the positioning by means of the wireform 12. For example, the cavity inside the C-profile 26 may initially be filled with styrofoam foam, so that the concrete does not penetrate into it. After the concrete has hardened, socket bolts 28 can be inserted into the C-profile 26, for example to secure wooden beams to a roof structure.

In Fig. 5 is a cross section through a formwork element 2 as shown in FIG Fig. 1 shown, however, a bracket 30 is placed on the upper reinforcing elements 10. The bracket 30 in Fig. 5 consists of an example of a double bent by 90 ° wire, but there are other forms of space and configurations of the bracket 30 possible. The bracket 30 engages over the upper reinforcing elements 10 from above and lies with his traverse on this. The legs 32 of the bracket 30 extend far into the formwork space 8 and extend in the vertical direction to a depth in which they overlap one piece with the legs of the connecting element 6. Thus results between the legs 32 of the bracket 30 and the legs of the connecting element 6, an overlap region 34. Together, the connecting element 6 and the bracket 30 surround the reinforcing elements 10, which are located within the ring formed by these two components. In order to form a strapping, the bracket 30 and the connecting element 6 need not be connected to each other, the mechanical connection is made by the surrounding matrix of the filling compound such as concrete. For positive connection of the bracket 30 has two hook-like portions 36 which are bent in a direction deviating from the direction of force in which the bracket 30 has to absorb forces.

In Fig. 6 an embodiment is shown as a composite of two brackets 30a, 30b strapping ring can be formed. The two brackets 30a, 30b are formed in this embodiment to identical cuboids, which are placed inside each other. The legs 32 of the two brackets 30a, 30b form towards the sides in each case over the full height of the cuboid extending overlap region 34. While the upper cross members of the strapping originate from the yoke 30b, the lower cross members are integral with the yoke 30a. In the extension direction of the reinforcing elements 10 of the bracket 30 a forms a U-shaped and upwardly open shell, in which the reinforcing elements 10 are inserted and on the afterwards the bracket 30 b can be placed. The combination of the brackets 30a, 30b may, for example, form a double strapping in a section between two connecting elements 6. The reinforcing elements in Fig. 6 are indicated by dashed lines and extend in the normal case over a greater length than the length of the bracket 30 a, 30 b, the short representation of the bar steels in Fig. 6 as well as the lack of representation of the side shuttering panels is only the drawing simplification.

The invention is not limited to the embodiment described above. The above explanation is only illustrative of the invention. It is not difficult for a person skilled in the art to adapt the subject matter of the invention as defined in the claims to a given application in a suitable manner.
