Description

Description [0001] The invention relates to a seal assembly for sealing a potting cavity between at least two components. When constructing with prefabricated concrete parts often concrete parts are erected one beside the other, and open casting recesses are filled with grouting mortar. The concrete compounds put one beside the other, such as for example wall slabs, wall slabs and pillars, have a recess on their narrow front side, two opposite recesses forming a larger potting cavity. However, a gap with a width of roughly 2 cm remains between the adjoining concrete parts. This gap has to be sealed so that in the grouting hole remaining on top grouting mortar can be filled.

[0002] Presently there are several options closing such a gap for delimiting the potting cavity. For example, on the left and right hand side of the wall component a board or strip shuttering can be provided. This is expensive and not sufficiently sealing when highly viscous grouting mortars are used. Sometimes foam is sprayed in these recesses serving as delimitation after hardening. However, eventually this solution does not look appealing and therefore can only be used for hidden components. Joint tapes inserted in these gaps are supposed to serve the purpose. Pressed-in lead strips are supposed to serve the same purpose. All elements have the disadvantage of not being sufficiently sealing when the mortar is liquid, and are not up to the stress because of the partly rather high pressure. At least in the bottom area casting compound or mortar escapes from the potting cavities.

[0003] From citation EP 0 663 977 B1 a prefabricated component of reinforced concrete and a building constructed therewith has become known where a strip is inserted between two abutting slabs. However, this strip cannot seal the space inbetween. According to this solution it is rather possible that casting compound escapes from the recesses, and this is expensive to remove.

[0004] From the German utility model G 91 12 112.4 a socket joint has become known. In this solution, suitable in particular for the use in canal construction, a seal ring made from elastomer material is known sealing two pipes that are slid into one another in the area of a sleeve by deforming.

[0005] From citation DE 38 15 142 an activated seal has become known used in particular in tunnel construction for sealing concrete elements. However, this seal does not seal a potting cavity, it rather completely fills the space provided for the seal.

From Citation DE 42 02 005 A1 a sealing device for abutting components, in particular molded concrete parts, has become known used in particular for sealing wellrings with annular surfaces arranged one above the other. The core of the solution is here that in the seal cavity a hardening material is contained that first spreads under the pressure of the concrete part and then hardens. Thus in the end its forms a rigid, non-deformable core. From citation EP 0866190 a sealing assembly for sealing joints has become known where a joint sealing hose is put or inserted in the joint, and then the hose is pressurized by inside pressure so that the walls of the hose are pressed against the walls delimiting the joint and thus seals the joint completely.

[0006] From citation DE 200 20 504 a formwork element as lost formwork has become known where a potting cavity is sealed by seal strips, that are not described in detail. The design of the seal strips is not contained in the description of the utility model.

Furthermore, from citation DE 101 09 717 also a seal assembly has become known where a space is filled by an elastomer material.

Another seal assembly has become known from citation DE 198 26 482 A1 has become known, where two abutting components from concrete, metal, reinforced concrete, cast iron or other materials interact towards one another with a seal profile from elastomer material in a sealing way. The sealing profile is provided with different grooves that are supposed to improve the sealing effect of the components among one another. A potting cavity is not defined here.

Therefore it is an object of the invention to develop a solution that in particular securely seals the potting cavity between two components that have to be joined while the grouting mortar or casting compound is filled in. The production and use of the solution should be uncomplicated.

[0007] The problem is solved by a seal assembly according to claim 1. According to the invention the problem is solved by pressing an elastically deformable or formable article as seal in a gap between the components, the article widening by expansion because of inside and/or outside interference and resting against the adjoining areas. The inside and/or outside interference can be a supply of material, energy or the like. For example, this seal can consist of a hollow body such as a hose. It can be pressurized via a filling device. For removing the pressure can be discharged and the hose taken out.

An embodiment of the invention is characterized in that the seal is smaller or equally dimensioned compared with the gap. The seal is inserted before grouting, and then expanded by interior or exterior interference; different options are possible here. For example, interior pressure for expansion can be generated by pressurizing with compressed air, pressurizing a liquid medium that is under pressure or by a chemical reaction of two chemical elements so that here also contact pressure occurs acting against the flank of the joint. Also exterior influence, such as applying current or chemical means can be used for generating contact pressure, according to the invention, for widening or expanding. By means of this pressure out of the component counter contact pressure for pressing contact is generated so that the seal reliably seals the gap. Then the casting compound can be filled in as usual. The seal is here completely tight, and there are no ugly points where the material escapes that, if necessary, have to be removed after hardening. The seal has here the advantage that it can be used as “lost formwork” as well as “recycled formwork”. The invention comprises both possibilities. Furthermore, this goes for the seal that can be influenced form outside as well as the one influenced from inside.

[0008] Of course, both described modifications can be combined with each other by additionally pressurizing a seal, influenced from outside, also from inside, for example by interior pressure.

[0009] Referring to the components it is important that these may be prefabricated concrete parts or components constructed according to the so-called frame construction, and have been placed one beside the other. Flowever, for example, it may also be a support to be arranged next to a concrete wall or a built wall. It may also be building components produced in monolith procedure. Connection joints in concrete and/or masonry construction are also comprised by the invention. Furthermore it is possible to provide steel beams, aluminum beams, composite girders, concrete beams or the like as components that have to be connected by means of casting. Here also the seal according to the invention can be inserted in the gap between the parts.

[0010] Another field of application, also comprised by the invention, is the use in formwork parts or elements. Adjoining areas of shuttering panels or shuttering components can be sealed by the seal according to the invention. It is assumed here that in also in formworks, in particular large-sized formworks for foundations high liquid pressure occurs because of the filled-in mortar or casting compound that can also leave through the gaps in the shuttering components themselves or between two shuttering components. During stripping the formwork these concrete parts, that have escaped and are then hardened, have to be removed. In addition to that the shuttering elements or parts are difficult to remove from the concrete elements because of the meanwhile hardened concrete, leading to an increase of manual labour for stripping or destroying shuttering panels or components. This is avoided completely by means of the seal according to the invention if it is used between shuttering panels and components.

[0011] Compared with the citations of the state of the art described in the beginning, the solution according to the invention is characterized in particular in that, for example in EP 0 663 977 no seal is shown expanding by outside or inside impact and generating a contact point to the components for sealing the gap between the components. The citation describes, and in particular shows in its drawings, that the strips are inserted in cavities. These strips are cut off from hardboard or formed by insulating material.

[0012] It is obvious that these strips cannot produce any sealing effect through contact pressure. Another seal described in this citation serves for preventing water from intruding, for example in basement walls. However, it is not described how this I supposed to be performed. This method is not suitable for solving the problem of the invention, namely safely sealing of potting cavities.

[0013] Compared with the solution described in the citation G 91 12 112.4, the solution according to the invention is characterized in that it serves for sealing potting cavities that have by no means been mentioned in the known citation. The solution according to the state of the art is rather a socket joint employed for example when connecting pipes of concrete, reinforced concrete, artificial resin or the like in canal construction. The solution described in citation G 91 12 112.4 U1 seals the gap between the two adjoining pipes in the area of the sleeve. There is no casting with casting compound such as in the solution according to the invention.

[0014] Citation DE 38 15 142 A1 describes a solution with a seal that can be activated. The seal, known as “segment seal”, serves for activating two profile tapes that lie on top of each other. The cavity according to the solution described in citation DE 38 15 142 A1 is filled completely with the appropriate seal or seals., i. e. that no more concrete or casting compound can be filled in. The solution can be used in particular in tunnel construction, for example to prevent humidity from intruding between two adjoining concrete elements in tunnels. Casting is neither provided nor described.

[0015] The solution according to the state of the art of DE 42 02 005 A1, described in the beginning, is suitable for sealing wellrings arranged one on top of the other. In the interior of the seal a hardening material has been filled in that is in particular still flexible during mounting, and that is able to compensate certain differences of measures, as they may occur with concrete parts. When the well ring is mounted accurately the seal compensates these imperfections, and after a certain period of time hardens so that a permanent sealing is accomplished. Internal or external pressure cannot be produced by this seal, it rather avoids connected or generated pressure.

The next citation of the state of the art describes a seal assembly comprising two abutting components forming a gap, wherein here a sealing body made from elastomer material is described bridging the gap while it seals it. Also a lubricant is described for the contact surfaces between the respective components and the sealing body, wherein the lubricant is made such that first, during installation, it has a sliding effect, and after installation it occurs as cold vulcanized glueing means. A change of the sealing body, for example by inside or outside pressure, cannot be found in this citation. Accordingly, the problem according to the invention cannot be solved by means of this citation. In contrast to that, the invention solves the problem in an excellent way and has in particular the advantage that sealing surfaces occur that are not characterized by escaping and hardened mortar beads or casting compound. Finishing these escaped mortar beads is a very laborious work, and eventually the visible surface is damaged.

[0016] In contrast to all solutions of the state of the art the solution according to the invention is excellently characterized in that a proper connection or end of the respective gaps or joints is accomplished between the concrete parts, that casting compound cannot escape from the potting cavity during filling-in and setting so that visible concrete surfaces can be produced that do not need any finishing. The seal according to the invention can be employed universally such that the contact pressure can remain for the time being by outside and/or inside pressurizing of the seal until the casting compound has been hardened. After that the seal can return to its initial condition, for example in certain embodiments of the invention, or pressurizing can be removed along with the influencing. This provides a solution that complies with all requirements and is suited for the problem of the invention.

[0017] The invention also comprises a solution where the seal is characterized in that it is deformable such that it is deformed by interior and/or exterior stress, and, in particular when relieved, returns to its initial position. Such a design is provided for multiple use. When the seal has returned to its outside initial position it can easily be removed from the gap between the components and, in particular, from the meanwhile hardened casting compound. There is, of course, also the option of leaving this seal, while keeping up the outer impact, as so-called lost framework in the construction.

[0018] A particularly advantageous embodiment of the seal according to the invention is characterized in that it is configured as deformable hollow body. A hollow body can be excellently influenced by impact from inside.

[0019] For example pneumatic or hydraulic pressure can be applied. Furthermore chemical compounds reacting with one another can be filled in the hollow body. In a certain way the deformable hollow body is flexible so that it can develop appropriate contact pressure towards the sides of the joint gaps. The sealing part designed as hollow body is in particular provided as longitudinally extending hollow body that can fill certain length of joints without any problems and without intermediate seal or gap. Deformable hollow bodies are accordingly hose-like, however they may have very different diameters. The invention uses square, sandglass-shaped, rectangular, circular or oval cross sections. In particular the invention is not limited to one of the pre-described shapes, but is rather characterized by a multitude of different designs.

[0020] As already mentioned it is possible to pressurize the interior of the hollow body. This can be done, for example, by pneumatic pressure, by filling compressed air in the hollow body via provided inlets. The same can also be accomplished with water or other liquid media that are pressurized. Of course, it is particularly favorable when the seal is designed hose-like.

[0021] According to a modification of the invention it is provided that the seal expands by connecting with electric power or voltage and preferably returns to its initial state when shut off. This embodiment has actually the option of using re-usable seals for the task of sealing of potting cavities.

[0022] As already mentioned it is provided, according to a clever configuration of the invention that the interior of the seal contains a chemical compound that expands when reacting with at least one other chemical substance. The other chemical substance may be a liquid as well as a gaseous medium. Preferably the seal returns, when the chemical reaction decreases, to its original position. If the seal is supposed to remain as visible surface in the building the above-described design can be configured such that the seal remains, after the end of the chemical reaction, in its expanded shape.

[0023] Furthermore the invention provides that the seal is deformable by mechanic interference such as, for example, extension, shortening, cross deformation or the like. Different mechanic designs are possible here. For example it is possible to press the seal by means of lever tension towards the joint gap surfaces. This embodiment is also comprised by the invention. It is also possible that the deformable article is subjected to the following mechanic impacts from outside and/or inside, such as extension or shortening of an interior tightening strap with contractions of the pressure envelope and outward expansion.

[0024] Another development of the invention provides that the seal can be deformed by changing the temperature. It is an advantage here when the seal can be removed from the gap after the casting compound has hardened because the shape has returned to its original temperature.

[0025] The seal has at least one filling and/or emptying device. As an example hose connections with a valve are mentioned here. As already mentioned, the seal can be internally pressurized either with a liquid medium or a gaseous medium. The seal itself is deformed, for example by changing the volume in particular inside the seal.

[0026] Furthermore it is an advantage when the seal is designed as hollow body provided inside with expandable material. This expandable material expands under certain impacts and returns to its initial condition after the impact has been removed.

This seal also accomplishes the advantages according to the invention as described further above.

[0027] Sealing a joint gap by means of the sealing is carried out as follows. First a seal as described before is put or pressed in the occurring gap between the structural components or parts, and, if necessary, aligned at the contact surfaces. Then contact pressure is generated by exterior and/or interior impact on the seal at the contact surfaces of the seal with the components or building parts. Then an in particular hardening casting compound is filled in the potting cavity.

[0028] If the seal is not supposed to remain in the structure, after setting of the casting compound the seal is returned by removing the interior and/or exterior interference to its original condition and removed.

[0029] The invention also suggests a component assembly consisting of two adjacently arranged components with at least one front side per component configured as side of a joint gap and facing each other, that delimit at least partly a potting cavity between the components, wherein the potting cavity can be filled with a hardening casting compound, and with at least one seal according to one or more of the before-described embodiments of the seal arranged in the gap between the structural components or parts.

[0030] In the drawing the invention is presented schematically in particular in examples. In the drawings:

Fig. 2 arrangement of two seals according to the invention between two components,

Fig. 3 another embodiment of a seal assembly with seal according to the invention,

Figs. 4a, 4b, and 5 schematic presentation of the installation method of modifications of the seal according to the invention,

Fig. 9 representation of the principle of another modification for a seal according to the invention, and

Figs. 10a to 10d other modifications of the seal according to the invention.

[0031] All figures show seals 1 each arranged between two components 3. Accordingly in all presentations also an arrangement of components is shown as already described further above. The components may be designed here as prefabricated concrete parts, built elements, or, as already mentioned, as formwork elements, supports or the like. The invention is not restricted here to a use between two components 3, for example concrete components. Furthermore it is mentioned that the schematic reference number 4, provided with a dashed line and an arrow, indicates outside and/or inside interference 4. This outside and/or inside interference 4 has to be understood in that way that actually in several embodiments it expands by an exteriorly acting impact and applies a force leading to an interior pressure 10 guiding the pressing force of the seal 1 towards the surfaces of the joint gaps 2.

[0032] Of course, this creates a counter contact pressure 6 out of the components 3 that is also indicated schematically by arrows. Of course in all embodiments showing this modification also an additional inner impact by an interference by pressure or another already described possibility of interference is possible. For example, interior pressure can be generated by pressurizing with compressed air or water under pressure. This may be the only interference in the simplest embodiment. Of course, it is also possible to press a seal 1 according to the invention already with pressure (outside interference) into the gap 7, and additionally then to generate an inner interference in the form of pressure or chemical impact or be connecting to electric power. The examples are not to be understood restricting only in one direction according to which only an outside interference is shown and claimed.

[0033] In the figures identical or corresponding elements each are indicated by the same reference numbers and therefore are, if not useful, not described anew.

[0034] Fig. 1 shows a seal 1 according to the invention supported on two adjoining components 3 through outside interference 4. This is executed in the area of the gap 7 at the adjoining surfaces of the joint gaps 2. The outside interference 4 generates counter contact pressure 6, and via frictional forces 9 the formwork pressure 5 inside the potting cavity 8 can be carried by the seal 1. As already described before, additionally there may be an inside interference.

[0036] Fig. 3 shows another arrangement of a potting cavity 8 between two components 3, the wall is here on the left hand side and the support on the right hand side. Gap 7 delimiting the potting cavity 8 is sealed by the seal 1 according to the invention that is pressed to the surfaces of the joint gaps 2 by an outside interference 4, and thus creates counter contact pressure 6. An additional force (not shown, but comprised by the invention) is introduced with an inside interference 4.

[0037] Fig. 4 shows a potting cavity in parts with two adjoining components 3 and the remaining gap 7.The seal 1, according to the invention, is pressed in the gap 7 and elastically deformed, expanded by outside interference and thus results in counter contact pressure 6 at the surfaces of the joint gaps 2. Additional inner and/or outer interference later can further expand the seal 1 in order to increase the counter contact pressure 6 and to withstand an interior formwork pressure 5 by frictional fpowers 9 in active connection with the inside pressure 10 as well as the counter contact pressure 6.

[0038] Fig. 5 shows the seal 1 according to the invention in not yet expanded condition. An additional outside and/or inside interference 4 deforms the seal 1, according to the invention, such that it is in contact with the surfaces of the component 3 and withstands an inner formwork pressure of the potting cavity 8 by a suitable contact pressure 6.

[0039] Fig. 6a shows a seal 1, according to the invention, similar to the one in Fig. 5. But here the diameter is such that it fits exactly in the gap 7 between the adjoining components 3, is in contact with the surfaces of the joint gaps 2 and thus delimits the potting cavity 8. After that the outside and/or inside interference 4 can generate the necessary contact pressure.

[0040] Fig. 6b also shows a seal 1, according to the invention, expanding by outside and/or inside interference 4 and generating an appropriate counter contact pressure 6 and thus delimiting in the gap 7 at the surfaces of the joint gaps 2 between the adjoining components 3 the potting cavity 8 and thus being able to withstand a possible interior mortar pressure 5 of the casting compound.

[0041] The base of Fig. 6b may be the seal 1, according to the invention, either in Fig. 6a or Fig. 5. Flowever, a seal 1 can be employed having a diameter larger than the width of gap 7 so that it adopts an oval shape only by elastic squeezing. The outside interference 4 presses the seal 1 as described. An example is here an interior pressure 10 generated by outside interference and generating the counter contact pressure 6. Additionally an interior pressure 10 occurs by inside interference 4.

[0042] Fig. 7 shows two seals 1, according to the invention, in angular shape and being arranged each time in the gap 7 between two wall components and delimiting the potting cavity 8.The seal 1 is expanded by outside interference 4 and pressed to the surfaces of the joint gaps 2 of the components 3 and thus generates counter contact pressure 6 and enables it to withstand inside mortar or formwork pressure 5 by the frictional powers 9.

[0043] Fig. 8a shows a seal 1 according to the invention that is slightly pressed by exterior influence as outside interference 4. Fig. 8b shows how the seal 1 according to the invention comes into contact with the surfaces of the components 3 in gap 7 for delimiting the potting cavity 8 through the exterior influence. The shown exterior influence as outside interference 4 generates counter contact pressure 6 that is able to withstand there interior formwork pressure 5 by frictional forces 9.

[0044] Fig. 9 basically shows the seal 1 according to the invention adopting a radially expanded condition 11 by outside interference 4 and thus being pressed in the gap 7 between adjoining component 3. Figs. 10a, 10b, 10c, and 10d show modifications how the seal 1, according to the invention, is sealed by a closure 12 on a longitudinal delimitation. Fig. 10a shows on the end side a plastically glued-in closure 12 in the seal 1, according to the invention, in the shape of a hollow body.

Fig. 10b shows a rubber-elastic closure 12 with identical diameter as the elastically deformable seal 1, according to the invention.

Fig. 10c shows a stopper-like closure 12 that is wedged at the end of the seal 1, according to the invention. The wedge-like design of the stopper 12 presses it to the wall of the elastic seal 1, when pushed in, and remains there because of the friction even under interior pressure 10 of the seal 1.

Fig. 10d shows a typical pressure closure through which the inside and/or outside interference 4 as impact can be introduced for example by compressed air or water pressure through a valve 13, and internally pressurizes the inside of the article according to the invention in the shape of a hollow body. Via valve 13 pressure can be applied or removed, that means the interior pressure as inside interference 4 according to the invention can be controlled.
