Description

The invention relates to a device for building a concrete formwork for use in a system for building a concrete formwork and also such a system for building a concrete formwork.

In the production of precast concrete parts, the form to be produced is set up on a formwork table (base plate) consisting of several formwork elements and then poured with concrete. The formwork table is made of magnetic material, so that the formwork elements can be held by means of magnetic bodies relative to the formwork table. The formwork elements comprise a wood or metal plate, which is in direct contact with the concrete. Usually, corresponding projections or holders (a type of frame) are attached to this plate, which cooperate with the magnetic bodies to fix the plate in a vertical or angled orientation relative to the formwork table can.

Modern formwork systems can also work with shuttering robots. The individual formwork elements and the magnetic body are then from a robot automatically positioned on the formwork table and after casting the precast concrete also removed or collected. The advantage of such a robot system is, among other things, that the positioning of the formwork elements can be extremely accurate and independent of manual work on site.

In the EP 0 639 686 A2 describes a formwork system for production plants, with which a large number of precast concrete parts can be manufactured quickly and rationally. From individual formwork elements, the required formwork is assembled and attached via appropriate bracing or coupling elements with magnets on a steel plate.

Depending on the shape of the prefabricated concrete part to be produced, different forms of formwork or shuttering elements are required. A challenge in modern production facilities is the efficient production of a wide range of different shapes. For this purpose, it is often necessary vorzuhalten a variety of different formwork elements in order to build the shape to be produced on the formwork table can. In particular, sufficient quantities of formwork elements of different heights and lengths or widths are necessary. In addition, often application-specific formwork elements are required, the z. B. have recesses for protruding reinforcing iron.

This variety of different formwork elements means that the production costs increase, that often the production is slowed down, and that long travel distances of the formwork robots must be taken into account. In addition, the diversity of existing forms is ultimately always limited, so that also exist with regard to the finished concrete parts to be manufactured restrictions.

The object of the present invention is therefore to provide a modern formwork system in which the flexibility is increased with respect to the shapes to be produced. It is to be created a structure of a formwork, which can be used efficiently for a variety of manufactured forms of precast concrete parts.

According to a first aspect of the present invention provides a device for building a concrete formwork with an upper cross member and a lower cross member for holding a formwork wall opposite a formwork table, wherein the lower cross member is adapted for coupling to a fixing element for fixing on the formwork table ; a plurality of identically shaped connecting parts for detachably connecting the cross members at variable positions along a longitudinal axis of the cross members, the two cross members extending parallel to each other; and wherein a distance of the cross members is determined by a length of the connecting parts to each other.

In another aspect, the invention provides a formwork system for building concrete formwork with a device as defined above; a formwork wall; a formwork table; and a fixing member for releasably securing the device to the formwork table.

In the apparatus according to the invention, two cross members of variable length can hold a separately formed shuttering panel relative to the shuttering table. The formwork wall is preferably fastened to the two cross members. The lower cross member can be fixed with a fixing element on the formwork table or held relative to the formwork table. The two cross members are connected to each other according to the invention with connecting parts. These connecting parts have identical design and set the distance of the cross member to each other. The cross members are parallel to each other, their longitudinal axes are aligned in parallel. When set up, the device according to the invention holds a formwork wall opposite the formwork table.

In contrast to previous formwork systems or corresponding holding devices, the device according to the invention in the sense of a modular system be built variable and also disassembled again. The device is thus modular in that it consists of a few simple components which can be combined and assembled in a variable manner so as to allow the construction of a formwork of more or less any size.

Usually, a kit with cross members and connecting parts of different lengths and with different sized formwork walls is available. From the kit according to the invention now cross member corresponding length can be selected, which thus define the maximum length of the formwork wall or the concrete part to be manufactured. Furthermore, connecting parts matching height can be selected, which determine the maximum height or thickness of the concrete part to be manufactured. Connecting parts and cross members are detachably connected to each other and hold the formwork wall.

Due to the flexible structure of the device according to the invention is achieved that from a few basic components, a variety of differently shaped precast concrete parts can be produced. The number of required parts is reduced. Costs are saved and the efficiency or manageability in the production are increased.

Apart from this, it is often necessary that reinforcing bars protrude at different points from the concrete part to be produced. In previous formwork systems with prefabricated formwork elements, it was usually not possible to provide corresponding recesses in the formwork elements. At least such recesses could not be provided at any point depending on the construction of the formwork element anyway. In the device according to the invention, however, it is possible that the connecting parts connect the cross member at different (variable) locations. The positioning of the connecting parts along the longitudinal axis of the cross member is selectable, so that the flexibility in the production is further increased.

Preferred embodiments of the invention are described in the dependent claims. It will be understood that the system may be embodied according to the embodiments described for the device in the dependent claims.

In a preferred embodiment of the device, the upper cross member and the lower cross member are formed identically. If, in addition to the connecting parts, the cross members are also identical, the number of required components is further reduced. It is only necessary to keep available connecting parts in different lengths and cross members of different lengths in stock. Depending on how long the cross member and the connecting parts are selected, a formwork wall virtually any size can be kept on the formwork table.

In a preferred embodiment, the upper cross member and the lower cross member have a U-shaped profile with the U-backs facing each other. By using a U-shaped profile maximum stability is achieved with low weight. The manufacturing cost of the carrier and the transport and storage costs are reduced. Preferably, both cross beams are aligned in the assembled state of the device against each other, so that the backs of the U-shaped profiles are oriented to each other. As a result, a high stability can be ensured with low weight.

In a further preferred embodiment, the upper cross member and the lower cross member along their longitudinal axes in each case a plurality of, the other cross member facing holes; and the connection parts for connecting the cross member are formed on opposite holes of the cross member. Preferably, the cross members each have a hole pattern with identically spaced holes along their longitudinal axes. The cross members or their holes are designed so that the connecting parts can be connected thereto. In particular, a Screw connection may be provided, wherein the connecting parts also have (screw) holes which correspond to the holes in the cross members. Then, each side of the connecting part can be screwed to two opposite holes on both cross members and fixed at a position along the longitudinal axis of the two cross members. A simple attachment of the connecting parts at an arbitrary position along the longitudinal axis of the cross member is achieved. The connecting part can be easily attached to other holes of the plurality of holes, so that can be left for reinforcing iron, which protrude at a predetermined position from the concrete to be manufactured, space.

In a further advantageous embodiment, the device comprises an adapter piece for fastening to the formwork wall to be held and at a variable position along the longitudinal axis of the upper cross member and / or the lower cross member. The formwork wall can be attached directly to the cross members and / or to the connecting parts. It is also possible that an adapter piece is provided, which can be fastened on the one hand at a variable position along the longitudinal axis of at least one cross member and on the other hand on the formwork wall. For example, may be provided for fastening a screw. By using an adapter piece a quick attachment and detachment of the shuttering wall to be kept possible. For this purpose, the cross member may also have a hole pattern on its side facing the formwork wall.

In a further refinement, the device comprises a coupling element fastened on the side of the upper cross member facing away from the formwork table for coupling the device to a handling traverse or to a robotic arm of a carrying robot (often also referred to as shuttering robot). It is possible that a coupling element (also referred to as Greifknof) is provided directly on the top of the cross member, which is attached to the device and with which the entire device fixed to a handling traverse or lifted and moved by the carrying robot can. Preferably, a standard coupling is used for receiving a handling crossbar. Handling is simplified, a more efficient production of precast concrete parts is achieved.

In a further embodiment, the upper cross member and the lower cross member each have a plurality of the formwork wall facing holes, which are formed for securing the formwork wall. By a hole pattern on the formwork wall facing side of the upper cross member and the lower cross member of the effort for fixing the formwork wall can be minimized on the cross member efficient handling and rapid production of a corresponding formwork are achieved.

In one embodiment, the upper cross member and the lower cross member for coupling to adjacent cross member of a second, in principle, identically formed device are formed. Several cross members can be arranged behind each other, so as to be able to represent a greater overall length. For example, several short cross member can be connected to hold a large formwork wall can. In this case, a corresponding connecting element may be provided which connects the cross members to be connected by screwing on the hole grid. The number of components to be kept is further reduced; the efficiency in the production is further improved.

In a preferred embodiment, the connecting parts have a U-shaped profile. By a U-shaped profile high stability is achieved with relatively little weight. Easy manufacturability is achieved.

In a further embodiment, the device according to the invention comprises a screw connection for fastening the connecting parts to the cross members. The connecting parts are thus screwed to the cross member. As a result, a simple and quick assembly of the device is ensured. The efficiency is further increased.

In an expedient and advantageous embodiment of the formwork system according to the invention, the formwork wall has at least one recess for performing reinforcing iron; and the connecting parts and the cross members are arranged so that an alignment of the recess neither a connecting part nor a cross member intersects. Due to the fact that in concrete parts often reinforcing bars have to protrude from the edges at predefined locations, it is necessary in the production that the shuttering wall has corresponding recesses through which reinforcing bars can protrude. The device according to the invention allows the implementation of reinforcing iron through the recesses in that in the alignment of the recess no connecting part is arranged. The connecting part is offset relative to the longitudinal axis of the cross member (and secured at another location) so that the recess remains free. As a result, a high degree of flexibility in the positioning of the reinforcing iron is guaranteed to be produced in the precast concrete part. Good manufacturability of precast concrete with differently positioned reinforcing bars is achieved.

In a further preferred embodiment, the fixing element comprises a magnetic body or a magnetic box for magnetic attachment to the formwork table. This magnetic box allows a quick coupling and release of the device on the formwork table. The desired shape of the concrete part to be manufactured can be reproduced quickly and efficiently on the formwork table.

In a further embodiment, the fixing element comprises a clamping piece fastened to the magnetic box for clamping the lower cross member between clamping piece and shuttering table. When the magnetic box is placed on the formwork table, the clamp clamps the lower crossbar firmly onto the formwork table. The magnetic box is attached to the clamping piece. The use of the clamping piece enables a standard magnetic box to be used. A standard part allows a cost-efficient production.

Preferably, the shuttering wall made of wood and / or metal; the formwork wall is made up of several layers; and / or has the shuttering wall profiling on a surface facing away from the device. The device according to the invention also allows flexibility and easy interchangeability with respect to the formwork wall used, in particular with respect to its surface.

It is understood that the features mentioned above and those yet to be explained below can be used not only in the particular combination given, but also in other combinations or in isolation, without departing from the scope of the present invention.

In FIG. 1 a device 10 according to the invention for the construction of a concrete formwork is shown. The device 10 comprises an upper cross member 12 and a lower cross member 14 which are interconnected by at least two identically shaped connecting parts 16. In the connected state, the cross members 12, 14 extend parallel to each other insofar as their longitudinal axes are aligned parallel. By the length of the connecting parts 16, the distance of the cross member 12, 14 is defined to each other. The cross members 12, 13 have an identical cross section in the form of a flat U.

The connecting parts 16 are detachably mounted between the cross members 12, 14. The connecting parts 16 are fastened both to the upper cross member 12 and to the lower cross member 14, each by a screw connection 18. It is understood that, alternatively, other releasable compounds such. B. a clamp connection or a hook system, etc. can be used.

The position of the connecting parts 16 along the longitudinal axis of the cross members 12, 14 is variable. The connecting parts 16 can thus be moved along the longitudinal axis of the cross member 12, 14 and secured at other locations. For example, it is possible that the screw 18 engages in another corresponding pair of holes of the hole pattern in the upper and lower cross member 12, 14. The positions of the connecting parts 16 along the cross member 12, 14 can therefore be varied. As a result, the resulting between the connecting parts 16 free spaces can be arranged as needed at different locations.

It is understood that at least two connecting parts 16 are necessary. However, at least four, more preferably at least six connecting parts 16 between the cross members 12, 14 are preferably used. In the example shown, the cross member 12, 14 are connected by a total of six connecting parts 16 with each other.

The device 10 according to the invention represents a modular system in which different sized connecting parts 16 and cross members 12, 14 can be freely combined with each other depending on the application.

In FIG. 2 By way of example, three different connecting parts 16 with different lengths h1, h2, h3 are shown. All connecting parts 16 have a U-shaped profile and are suitable for connecting the cross members 12, 14. The illustrated connecting parts 16 each have at least one hole for the connection in the legs of the U, which can be connected by means of a screw with the hole pattern in the cross member.

It is understood that the connecting parts 16, which connect the two cross members 12, 14, have the same length h1, h2 or h3. The total of six connecting parts 16 of the device 10 are identical. In the installed state (cf. FIG. 1 ), the connecting parts 16 are aligned so that the two legs of the U are oriented in the direction of the cross member 12, 14 and extend the back surface of the U at right angles thereto.

At the in FIG. 1 illustrated embodiment of the device 10, the upper cross member 12 and the lower cross member 14 are also formed identical.

In FIG. 3 four examples of cross members 12, 14 are shown. The cross members 12, 14 all have the same U-shaped profile, but have different lengths (along their longitudinal axis n) I1, I2, I3, I4.

The fact that it is possible to construct the device according to the invention from different lengths of cross members 12, 14 and connecting parts 16, it is achieved that the device 10 can be adjusted in size as needed. Compared to previous approaches to building a concrete formwork is thus ensured that only a number of different high connecting parts 16 and different lengths of cross member 12, 14 must be maintained, from which then devices in any size can be assembled in the sense of a kit. The storage of many formwork elements of different sizes is unnecessary.

In FIG. 4 a device 10 is shown, to which a formwork wall 20 is attached. In the example shown, the formwork wall 20 can be fastened with the screws 22 to holes 38 (preferably in the perforated grid) on the side of the cross members 12, 14 facing the shuttering wall 20. It is understood that alternatively other fastening means, such as nails, clamps etc. can be used.

The shuttering wall 20 is in contact with the concrete (not shown) and prevents the concrete from flowing through the interstices of the device 10. The precast concrete element is shuttered in this way.

In FIG. 5 is a formwork system 24 shown for building a concrete formwork. In addition to the device 10, the formwork system 24 comprises a formwork wall 20 which is fixed to the device 10, a formwork table 26 on which the device 10 is arranged and which serves as a base plate, and a fixing element 28, with which the device 10 on the formwork table 26 is attached.

In the example shown, three fixing elements 28 are provided, which fix the device 10 at several points relative to the formwork table 26. The fixing element 28 comprises a clamping piece 30 and a magnetic box 32.

The magnetic box 32 may be magnetically mounted on the formwork table 26 of ferromagnetic metal. The magnetic box 32 has for this purpose a housing with a U-shaped cross-section, in the interior of which a strong magnet is arranged vertically displaceable. By a pressure or shock on a protruding from the top of the housing actuator is the Holding magnet lowered to the base plate or the formwork table. By means of the same actuator, the magnet can also be released from the ground again, although the strong magnetic adhesion must be overcome.

The clamping piece 30 is connected to the magnetic box 32 and causes a force acting perpendicular to the formwork table 26 on the lower cross member 14 clamping force by which the lower cross member 14 is pressed onto the formwork table 26. The lower cross member 14 or the entire apparatus 10 and the formwork wall 20 can no longer be moved relative to the formwork table 26. By using the clamping piece 30 in the fixing is achieved that can be used as magnetic box 32, a standard magnetic box, which is widely used. It is understood, however, that other embodiments of the fixing are possible.

The lower cross member 14 is designed so that a coupling to a fixing element 28 is made possible. In the present example, the lower cross member 14 is formed as a U-profile, wherein the flat back of the U has in the direction of the upper cross member 12. The lower cross member 14 is designed in its width and in its height so that it can cooperate with the fixing element 28 in order to allow a fixing relative to the formwork table 26.

In FIG. 6 an alternative embodiment of the fixing element 28 with an alternatively formed clamping piece 30 is shown. Due to the additional support of the clamping piece 32 on the formwork table on the side facing away from the device 10 of the magnetic box 32 results in a further improved clamping effect, which causes an even stronger setting of the device 10 relative to the formwork table 26 due to the leverage.

Furthermore, in FIG. 6 recognizable that two coupling elements 34 are arranged on top of the upper cross member 12. These coupling elements 34 are used for coupling the device 10 to a handling traverse or to a robot arm of a carrying robot (not shown). With such a carrying robot, the device 10 can be positioned precisely and automatically on the formwork table. This allows an automation of the production of formwork for precast concrete done.

The position of the coupling elements 34 with respect to the longitudinal axis of the upper cross member 12 can be varied. It is possible that one or more coupling elements 34 are arranged at different locations along the longitudinal axis of the upper cross member 12. In particular, screwing on at different holes 36 or at different positions of the hole pattern can be done.

In FIG. 7 It can be seen that the formwork wall 20 of the formwork system 24 has recesses 40, can be performed by the reinforcing iron 42. Such reinforcing bars 42 are very often contained in precast concrete elements, sometimes requiring that the reinforcing bars 42 project beyond the precast concrete section. Then the formwork must have corresponding recesses 40 for performing the reinforcing iron.

The device 10 allows due to the flexible positioning of the connecting parts along the longitudinal axis of the cross member, that a plurality of recesses 40 may be provided at arbitrary locations. In other words, it is possible that when a certain position of the reinforcing iron 42 is required, no connecting part is disposed at the corresponding position. The connecting part can then be placed at a different location next to a recess 40 so that the reinforcing iron 42 readily reach through the device 10 and can protrude on the side facing away from the precast concrete part of the device 10. In the alignment of the recess 40, ie in a direction of the projecting reinforcing iron 42, there is neither a connecting part nor a cross member 12, 14. The releasable connection of the connecting parts allows comfortable positioning at another location along the longitudinal axis of the cross member 12, 14th

In FIG. 8 three different ways of designing the formwork wall 20 are shown.

On the left side of a device with a shuttering wall 20 is shown, which consists of a profiled sheet. This shuttering wall 20 makes it possible to produce precast concrete parts which have a corresponding profiling on their formwork wall 20 side facing.

For larger formwork walls 20 a higher stability is necessary. On the right side a formwork wall 20 is shown, which consists of a wooden plate which is light but relatively thick. Such a wooden plate allows the production of smooth surfaces and can be made sufficiently stable at low cost to withstand even higher pressures. As a result, larger precast concrete parts can be produced efficiently. Such wooden formwork walls can be easily made on the construction site of boards so that they need not be transported from far away or kept in stock.

It is also possible a combination. The in the middle of FIG. 8 Formwork wall 20 shown comprises a wood panel and a laid sheet. Due to the multilayer composite construction, a high stability can be achieved with simultaneously arbitrary surface.

In FIG. 9 a further embodiment of a device according to the invention is shown. Two in principle identical devices 10 are connected to each other at their upper and lower cross members 12, 14. As a result, a long formwork can be provided without the need for very long cross members. The connection via two metal plates 44 which connect the abutting upper cross member 12 and the adjacent lower cross member 14 with each other. Also for this purpose, the holes 36 and the hole pattern in the cross members 12, 14 are used. Starting from a few Basic elements (cross member and connecting parts) can be built so a very large variety of different formwork.

In FIG. 10 a further embodiment of a device for building a formwork is shown. At the lower cross member 14 flat adapter pieces 46 are provided at different locations with L-shaped cross section, which are formed for securing the shuttering wall 20 to be held at a variable position along the longitudinal axis of the lower cross member 14. It is understood that a corresponding construction can also be provided on the upper cross member 12. In principle, the fastening of the formwork wall 20 can be improved by the use of adapter pieces 46. In this embodiment, in which only a single cross member 14 is used and thus is particularly suitable for the production of formworks of very low height, allows the use of the adapter pieces 46 that a sufficiently stable formwork can be constructed.

In the claims, the words "comprise" and "with" do not exclude the presence of further elements or steps. The undefined article "a" or "an" does not exclude the presence of a plurality. A single element or unit may perform the function of several of the units recited in the claims. The mere mention of some measures in several different dependent claims is not to be understood that a combination of these measures can not be used equally advantageous.
