Steuler-Industriewerke GmbH
Hohr-Grenzhausen ~oubl~-walled for~work el~me~t and procesR ~or manu~aaturi~g ~t The present invention relates to a double-walled formwork or lining element comprising two large-area panels suitable for use a~ mould shuttering, particularly in the concrete construction industry, as well as to a process for manufacturing it.
Shutterings or linings are used as chemically resistant, liquid-tight and gas-tight protection for a variety of applications, e.g. for concrete containers, pipelines, channels etc.
The EP-A-0 059 929 discloses formwork elements which consist of a lining panel composed of thermoplastic material and which are attached to for instance the wall of concrete constructions by means of a plurality of anchoring knobs.
For a number of cases, the shuttering must have a double-walled structurP; this applies particularly to containers, pipelines, channels etc. which are de~igned to contain or to convey highly water-polluting liquids or are subject to specific requirements for the purpose of preventing water and/or groundwater pollution. This means that for instance the container walls have to be protected by two liquid-tight and gas-tight layers of shuttering.
For this purpose, liquid-tight and gas-tight containers made o~ thermoplastic material are known which are for in~tance - .
placed into a concrete container lined with the above described panels. This measure has the disadvantage that e.g. the interior liquid-receiving container is not in force-locking engagement with the concrete construction and/or the lining panel directly fixed on the concrete.
Therefore, it cannot absorb any backward or lateral forces and is not secured against any shi~ts.
In contrast to this, it is an object of the present invention to provide a large-area for~work element suitable for use as mould shuttering and comprising two substantially parallel panels forming a continuous cavity between them, as wall as a process for manufacturing it, wherein the two lining panels are joined to each other by force-locking, liquid-tight and gas-tight engagement.
This object is achieved with the features of the claims.
The solution of the invention is based on the following ideas:
A first lining panel manufactured according to conventional methods which is provided with anchoring knobs welded onto it is connected to a second lining panel by means of a plurality of connecting knobs. The connecting knobs are affixed to the second lining panel, they are inserted into bores of the ~irst lining panel and welded to it to produce a liquid-tight and gas-tight joint. In this connection, the exposed part of the connecting knobs between the two lining panels determines the distance of the panels to each other.
In the case of e.g. a container, the first lining panel is secured to e.g. a concrete wall by means of the anchoring knobs in such a way that it lies on the concrete wall while the second lining panel is in contact with e~g. a liquid.

The solution of the invention is based on the following ideas:
A first lining panel manufactured according to conventional methods which is provided with anchoring knobs welded onto it is connected to a second lining panel by means of a plurality of connecting knobs. The connecting knobs are affixed to the second lining panel, they are inserted into bores of the ~irst lining panel and welded to it to produce a liquid-tight and gas-tight joint. In this connection, the exposed part of the connecting knobs between the two lining panels determines the distance of the panels to each other.
In the case of e.g. a container, the first lining panel is secured to e.g. a concrete wall by means of the anchoring knobs in such a way that it lies on the concrete wall while the second lining panel is in contact with e~g. a liquid.
The advantages of the present in~ention are that it allows the -two lining panels to be firmly joined to each other and :'
2~224~3 secured against shifts or slippage; any leak liquid produced may run off between the two panels. In addition, the formwork element according to the present invention also enables shuttering systems to be assembled cheaply and simply for constructions of variou~ shapes; furthermore, the joint between the lining panels is form-locking.
It is preferred that the individual parts of the formwork element, such as the two lining panels, the anchoring knobs and the connecting knobs, are made o plastics, thermoplastic materials being particularly preferred. It is possible to either produce the individual parts from the same material or from different materials.
In the following, the invention iq d~scribed in more detail with reference to the accompanying drawings wherein Fig. 1 shows a partial cross-sectional view of an embodiment of the present invention attached to a concrete wall, Fig. 2 shows a partial cross-sectional view of another variant of the embodiment of the present invention illustrated in Fig. 1, Fig. 3 shows a partial cross-sectional view of a shuttering system according to the present inventlon in the region of a lateral joint between two formwork elements, and Fig. 4 shows a partial cross-sectional ~iew of a shutterlng system according to the present invention in the region of an edge joint between two formwork elements.
According to Figs. 1 to 4, the formwork element consists of a ~ir.st and a second lining panel 2 and 4, respectively, which are joined to each other by a plurality of connecting . ::
~-` 21 ~2~ ~3 knobs 6 and form between them a continuous cavity 7. The first or outer lining panel 2 compri~es a plurality of anchoring knobs 3 on the side faced away from the second or inner lining panel 4, which anchoring knobs 3 allow the formwork element to be secured to e.g. the wall of a concrete construction (container, channel, pipeline etc.) in such a way that it lies on said wall. The second or inner lining panel 4 is in contact with the contents of the concrete construction, for instance a water-polluting liquid.
Fig. 1 exemplifies the connection of the second lining panel 4 to the first lining panel 2 which is secured in the concrete 1 by means of the anchoring knobs 3.
The connecting knobs 6 which are secured to the lining panel 4 (e.g. by welding or integrally) pass through the bores 5 in the lining panel 2 and are welded to the back surface of the lining panel 2. The connecting knobs 6 have a larger cross section than the bores 5 in their outer part which i~ faced towards the second lining panel 4 and adjacent to the first lini~g panel 2. Due to this, they rest on the lining panel 2 and form a deined distance, namely the cavity 7, to the panel 4. The joint between the connecting knobs 6 and the first lining panel 2 is liquid-tight and gas-tight, thus preventing li~uid or gas from entering behind the lining panel 2. Any leak liquid produced by leakages in the second lining panel 4 runs into the continuous cavity 7 and can be discharged. The connecting knobs 6 ensure a force-locking engagement between the first and the second lining panels 2 and 4, respectively; this allows backward forces to be absorbed and reliably prevents the lining panel 4 from shifting relative to the concrete construction.
Other embodiments are possible instead of the connection between the connecting knobs 6 and the lining panel 2 which , .
'~ 3 is shown in Fig. 1. The connecting knobs 6 may for instance be welded to the first lining panel 2 in its plane and not to its back surface.
In a further embodiment, the connecting knobs 6 may be connected to the first lining panel 2 by fitting them into it by means of a hot-press process.
The formwork element according to the present invention i5 preferably made of thermoplastic material.
In Fig. 2, the connecting knobs 6 are riveted to the back surface of the lining panel 2. The liquid-tight and gas-tight seal is achieved by acid-proof and/or alkali-proof O-rings 16 which are arranged on the shafts 17 of the connecting knobs, adjacent to the walls of the bores 5, and which are clamped between the connecting knobs 6 and the walls of the bores 5 due to the expansion of the shafts 17 occurring during the riveting. During the assembly of the formwork element, the O-ring 16 can ~e hold in place by conically widening the shaft 17, by means of a groove or by a force fit. The embodiment of the present invention shown in Fig. 2 also allows the combined use of different thermoplastics, for instance polyethylene (PE) and polyvinylidene fluoride (PVDF).
It i5 advantageou~ that several formwork elements according to the present invention can be combined to form a shuttering system, as shown in Figs. 3 and 4.
Fig. 3 shows the connection of two lining panels to the side wall of e.g. a concre~e construction 1. The first lining panels 2 are joined to each other at a ledge 11 by the weld 10 and sealed against the concrete wall. On the inward side of the formwork elements, the second lining panel~ 4 are welded w.ith a co~er ledge 8 at the welds 9 and are sealed against e.g. a liguid.
2~22~3 Fig. 4 shows an edge joint according to the present invention in a shuttering system according to the present invention. The first lining panels 2 are connected with each other by an edge joint ledge 13 (for instance at an angle o 90) that is welded with the lining panelæ at the welds 14.
The second lining panels 4 are joined to each other by e.g.
a quarter circle connecting piece 12 which is welded with the insides of the lining panels at the welds 15.
Within the scope of the present invention, edge joint ledges 13 having an angle greater or less than 90 and connecting pieces of different shape are also possible, according to the various concrete constructions (containers, channels etc.).
In addi.tion, the formwork elements according to the present invention with the cavity 7 formed between them may provide a leak detecting system; this makes the transport or storage of hazardous liquids considerably safer.
