Definitions

  • the invention relates to a joint filling profile for forming a joint seal between floor panels, with a vertical leg projecting into the joint and a profile body formed from a joint sealing compound and lying in a joint widening.
  • Joint filling profiles for forming a joint seal are well known per se from the prior art.
  • joint filling typically, the joint provided between two floor panels is sealed by means of a so-called joint filling. This can be done in a simple manner by filling the joint with a joint sealing compound.
  • joint filling profiles designed in such a simple manner have a disadvantageous shortage of service life, in particular when they are exposed to corresponding loads, as is often the case in industrial applications.
  • the DE 100 02 866 B4 a construction has been proposed, which is designed according to the free upper facing edges of adjacent floor panels a substantially horizontally extending joint widening, the joint being filled with joint sealing compound flush with the surface up to the joint widening.
  • vertical depressions so-called anchoring cuts, are formed in the end edge area of the joint widening, in which the profile body formed from joint sealing compound engages.
  • each of the floor panels provides an area adjacent to the vertical leg of the joint filling profile which is chemically and / or mechanically equipped so that the joint sealing compound introduced into the joint and the joint widening does not enter into a direct connection with the floor panel in this area.
  • joint filling profile has increased elasticity without the risk of it becoming detached from the subsurface, since in the areas in which there is no direct connection between the joint sealing compound on the one hand and the floor slabs on the other, expansion of the material forming the joint sealing compound is permitted is because in these areas only the material is stretched without being hindered by sticking to the substrate.
  • joint filling profiles are capable of EP 2 098 651 A2 to withstand higher mechanical and / or thermal loads, and this with a significantly reduced risk of unwanted detachment from the substrate.
  • a joint formation is known, according to which a joint remains unfilled, for which purpose a reinforcing element is provided which bridges the joint.
  • an adhesive tape is preferably provided, which is arranged in the edge regions of the reinforcement element.
  • a cover element can also be provided, for example in the form of an adhesive tape.
  • a method for preserving a soil cover layer is known. Accordingly, a floor is equipped with a top layer, the top layer having a binding layer made of a slightly viscous, flowable bitumen mortar.
  • the bitumen mortar contains a mixture of a cationic bitumen emulsion and a demulsifier with a mineral granulate in the form of a powdery filler.
  • the AT 375 984 B discloses a roadway transition for bridging joints present in the roadway substructure, which has a sealing membrane to cover the joint.
  • a cover that absorbs traffic loads is provided, which is located above the sealing membrane.
  • the WO 2007/053119 A1 relates to a method for applying a coating medium to structural elements, a stress redistribution structure being used to cover and bridge discontinuities within the structural elements.
  • the coating medium is above the Stress redistribution structure applied to this in such a way that the coating medium comes into contact with the surfaces of the structural elements outside the stress redistribution structure.
  • the invention is therefore based on the object of specifying a joint filling profile which eliminates the aforementioned disadvantages.
  • the invention proposes a joint filling profile for forming a joint seal between floor panels, with a vertical leg protruding into the joint and a profile body formed from a joint sealing compound and lying in a joint widening, the vertical leg and the profile body being separated from one another with the interposition of a separation material , with at least one second separating material between the vertical limb and the profile body and / or with at least one reinforcing mat being arranged within the profile body, the second separating material and / or the reinforcing mat being arranged at least partially overlapping with the first separating material.
  • each of the embodiments claimed according to the invention taken individually and in synergetic combination with one another, is suitable for eliminating the disadvantages prevailing in the prior art.
  • the double-layer arrangement of two separating materials which are preferably formed from metal foils, in particular from aluminum foils, enables further decoupling of the profile body and the vertical web compared to the prior art. This is in particular because the first separating material only has contact with the vertical web, but not with the profile body. On the other hand, the second separating material only has contact with the profile body, but not with the vertical web. In the case of stretching movements, the two separating materials, especially in the case of metal foils, can slide over one another completely freely.
  • the second separating material In contrast to the prior art, in which only a separating material is provided and in which adhesion on both sides can take place, there are no consequences for the adhesion of joint sealing compound to the foils.
  • the second separating material As an alternative material for the second separating material, besides being formed as a metal foil, it has also proven to be effective in the form of a fleece. This is because, on the one hand, it is impermeable to the joint sealing compound and, on the other hand, is able to slide over the first separating material, which is designed as a metal foil, in particular aluminum foil, with particularly low frictional resistance.
  • the two Separating materials can consequently be formed from the same material or from different materials.
  • the embodiment according to the invention comprising the at least one reinforcement mat advantageously prevents the disadvantageous crack formation that occurs in the prior art in the sections not covered by the first separating material. Material stresses occurring in these sections between the base plates and the profile body are completely absorbed by the at least one reinforcement mat.
  • the profile body preferably has at least one first section adjacent to the vertical web. A second section of the profile body adjoins the first section.
  • the separating material is arranged exclusively between the vertical web and the profile body and in the area of the at least one first section.
  • the second separating material is preferably arranged in the direction of the profile body above the first separating material and likewise exclusively between the vertical web and the profile body and in the region of the at least one first section.
  • the profile body has two first sections, which are formed opposite one another in cross section, adjacent to the vertical web on both sides.
  • a second section of the profile body preferably adjoins a first section.
  • the profile body can be designed to be axially symmetrical.
  • the reinforcement mat it is preferred that it is formed in a grid-like manner from longitudinal and transverse struts. As a result, the forces acting at the nodes of the respective struts are distributed over the entire grid. It is also preferred that continuous openings are formed between the longitudinal and transverse struts for the joint sealing compound. This ensures that the joint sealing compound of the profile body is in contact with the respective floor panels in the second sections. A separate separation between the profile body and floor panels, as with the EP 2 098 651 A1 was proposed, is no longer necessary due to the design according to the invention, since this function is also fully fulfilled by the separating material.
  • the reinforcement mat according to the invention serves to absorb the stresses going beyond this.
  • the edge of the one extending beyond the separating material Form the end of the reinforcement mat with a contour that changes in the longitudinal direction.
  • a variable contour is in particular a wave-shaped contour, a zigzag contour or a fringe-like contour.
  • alternating longitudinal struts and transverse struts form the respective end of the reinforcement mat.
  • the fringe-like contour has proven to be particularly advantageous.
  • the reinforcement mat can basically be formed from any material that is suitable for absorbing the stresses that arise. Mats made of metal, in particular metal wire, or plastic are particularly preferred.
  • the reinforcement mats are particularly preferably made of plastic. This is because, in addition to its known material properties, plastic interacts particularly well with the joint sealing compound, which is preferably formed from an elastic polymer resin. In synergy, this leads to particularly good voltage conduction between the profile body and the reinforcement mat.
  • a further reinforcement mat is provided.
  • the first reinforcement mat extends over the first and second sections running on one side of the joint.
  • the second reinforcement mat extends over the first and second sections running on the other side of the joint. This prevents the formation of cracks over the entire profile body.
  • the reinforcement mats are arranged leaving a gap that is aligned with the joint 2 in the vertical direction thereof.
  • the stress absorption is adapted to the axially symmetrical design of the joint filling profile. Both areas separated from one another by the mirror axis thus have a separate reinforcement mat. Different tensions in the respective areas can be absorbed individually.
  • the joint filling profile formed from the vertical leg and the profile body is not formed in one piece. Rather, it is provided according to the invention to separate the vertical limb from the profile body, specifically in that the vertical limb and the profile body are separated from one another with the interposition of a separating material. It is provided that the joint filling profile thereby to train that the joint is first filled so that the vertical leg of the later joint filling profile is created.
  • the vertical leg formed in this way is then equipped with a separating material on its upper side facing the widened joint.
  • a separating material on its upper side facing the widened joint.
  • This can be done mechanically or chemically, with the formation of a mechanical separation by the introduction of an intermediate layer being preferred.
  • a metal foil, in particular an aluminum foil, for example, can serve as the mechanical separating layer, which has the advantage that there are no thermal restrictions with regard to the use and processing of corresponding joint sealing compounds.
  • the profile body is then formed from a casting compound, the profile body being separated from the vertical limb due to the previously applied separating material. There is therefore no direct connection between the vertical leg and the profile body after the joint filling profile has been formed.
  • the separation according to the invention of the vertical limb and the profile body has the essential advantage that undesirable crack formation is avoided even in the transition area between the vertical limb and the profile body. Because, due to the lack of one-piece design, different material thicknesses are not formed, so that different expansion behavior due to different material thicknesses is prevented. Unwanted detachment phenomena, in particular flank tears, can thus be avoided even more effectively, thus resulting in an increased service life.
  • the profile body rests in a connection-free manner in a first section adjacent to the joint with the interposition of a separating material on the associated base plate.
  • This configuration advantageously allows the joint filling profile to stretch to compensate for mechanical and / or thermal loads to be able to afford, whereby due to the lack of direct connection between the profile body substrate in the above-described area there is no risk of tearing and / or detachment.
  • the lack of one-piece design of the profile body and vertical leg comes into play, since the profile body can expand both horizontally and vertically independently of the vertical leg, so the possibility of expansion of the profile body is not impaired by the vertical leg.
  • the lens effects that occur in a disadvantageous manner in constructions known from the prior art, that is to say constrictions caused by stretching, can thus be reduced or even prevented.
  • a multiplicity of reinforcements is embedded in the profile body, which reinforcements are arranged one behind the other in the longitudinal direction of the joint.
  • the purpose of the reinforcements is to prevent the profile body from buckling or bulging in the area where there is no direct connection to the subsurface in the event of expansion.
  • the reinforcement therefore ensures that the profile body, in spite of the above-described elasticity, terminates essentially plane-parallel with the adjacent floor panels even in the event of a load.
  • a reinforcement has a guide body on the one hand and a reinforcing element on the other hand, the reinforcing element being designed to be displaceable relative to the guide body.
  • the guide body receives the reinforcement element, so that there is no direct connection between the joint sealing compound of the profile body and the reinforcement element.
  • the reinforcement element therefore does not hinder the elasticity of the profile body. Rather, due to the relative displaceability of the reinforcement element with respect to the guide body, it is possible for the reinforcement element to join in with the movements of the profile body.
  • the guide body is also extensible, so that it does not prevent the profile body from stretching.
  • the guide body is a sleeve
  • the reinforcing element can be, for example, a rod, in particular a metal rod.
  • the rod is removed from the sleeve Is received longitudinally displaceably, the sleeve having a longitudinal extent exceeding the longitudinal extent of the rod. This ensures that in the event of the profile body being stretched, the rod can move accordingly within the sleeve and is not restricted in its movement, for example, by the sleeve.
  • the rod Due to the fact that the sleeve is made longer in the longitudinal direction than the rod, the rod can move inside the sleeve in the event of expansion, so that the expansion movement of the profile body is not blocked by the rod serving as a reinforcing element.
  • the reinforcement mats in the second sections rest on the floor plates with a spacer between them. It is also preferred that the reinforcement mats each rest on the separating material in the first sections. This ensures that the reinforcement mats are horizontal, i.e. are aligned parallel to the floor slabs in the joint widening. This achieves a particularly homogeneous stress absorption on the part of the reinforcement mats.
  • the reinforcement rests on the reinforcement mats.
  • it is supported by the interposition of the reinforcement mats on the spacers and can thus be precisely positioned in the widened joint.
  • the reinforcement extends into the second sections, but the connecting mats in the second sections extend beyond the reinforcement.
  • the profile body is designed to be axially symmetrical and has two first sections adjacent to the joint, each of which is followed by a second section. There is no direct connection between the profile body and the substrate in the area of the joint and the first two sections. Such a direct connection is formed in the outer second sections.
  • the separating material extends in the area of the joint and the two first sections adjacent thereto.
  • a continuous area is created in this way, which, starting from the first section of the first floor slab, extends over the joint to the first section of the second base plate extends, in which no direct connection of the profile body is formed with the ground.
  • the vertical limb and / or the profile body are temperature-resistant at least in sections up to a temperature of 60 ° C, preferably up to a temperature of 70 ° C, more preferably up to a temperature of 80 ° C is / are trained.
  • the joint filling profile is designed to be temperature-resistant, at least in sections.
  • the joint filling profile is therefore also suitable for installation in areas that are intended to be exposed to elevated temperatures.

It can also be provided that the vertical limb and the profile body are made from different materials, for example the vertical limb from a non-thermally stable material and the profile body from a thermally stable material.
  • granules made of a thermally stable material are added to the casting compound.
  • Such granules can be stone materials and / or graphite, for example.

  • the change in color of the particles is used in an advantageous manner to enable the user to visually check the joint filling profile designed according to the invention.
  • Physical and / or chemical influencing factors that can lead to a change in color of the particles added to the potting compound are, for example, mechanical pressurization, aging processes, the effects of chemical substances such as acid and / or the like. It is particularly preferred to add particles to the potting compound which change their color over time, that is to say over the service life of the joint filling profile according to the invention. In this way, the user can easily determine that the manufacturer's guaranteed service life of the joint filling profile has been reached, which is why it must be replaced to ensure functional reliability.
  • a change in color as a result of excessive mechanical stress is also advantageous, because, in particular, excessive pressure stress can lead to irreversible deformation of the joint filling profile.

  • the reinforcement mats 16, 17 rest in sections 14, 15 on spacers 18, 19, respectively. Overall, this ensures that the joint sealing compound 9 of the profile body 7 in the sections 14, 15 is in contact with the respective base plates 3, 4.
  • Each spacer 18 or 19 can have a bearing element which runs in the longitudinal direction of the joint and is supported by support elements.
  • the profile body 7 is thus largely free from stresses between the joint sealing compound 9 and the floor panels 3, 4.
  • reinforcements in the form of dowels 20 are arranged within the profile body.
  • the reinforcements are in this as well as in the other embodiments according to the Figures 1 to 3 optional.
  • a plurality of dowels 20 are provided, which are arranged one behind the other in the longitudinal direction of the joint 2.
  • the dowels 20 are preferably positioned adjacent to one another at equidistant intervals.
  • Each dowel 20 has a sleeve and a rod received by the sleeve.
  • a sleeve is formed longer in its longitudinal extension than the associated rod, that is, the longitudinal extension of the sleeve exceeds the longitudinal extension of the associated rod. This configuration makes it possible that the rod can move relative to the sleeve.
  • the reinforcement mats 16, 17 are arranged between the dowels 20 and the spacers 18, 19. The dowels 20 rest on the reinforcement mats 16, 17 at least in the area of the reinforcement mats 16, 17 on both sides.
  • the filler material 10 and the round cord 11 are first introduced into the joint 2.
  • the vertical leg 6 is then formed, in the illustrated embodiment by the introduction of the casting compound 9 into the joint 2, the joint 2 being filled at least flush with the base of the joint widening 5. It is not excluded here that part of the vertical leg 6 protrudes into the widened joint 5. Nevertheless, the vertical limb 6 and the profile body 7 are completely separated from one another by the separating material 8.
  • the respective joint-side end of the reinforcement mats 16, 17 can rest on the part of the vertical leg 6 protruding into the joint widening 5, with the interposition of the separating material 8.
  • the combined height of the part of the vertical leg 6 protruding into the joint widening 5 and of the separating material 8 corresponds to the height of the spacers 18, 19. This ensures that the reinforcement mats 16, 17 are aligned horizontally in the widened joint 5. In this way, a particularly homogeneous stress absorption on the part of the reinforcement mats 16, 17 is achieved.
  • the separating material 8 is then introduced, which in the exemplary embodiment shown extends over the joint 2 and the two first sections 12 and 13 of the floor panels 3 and 4, respectively.
  • the spacers 18 and 19 are then positioned within the widened joint 5, on which the reinforcement mats 16, 17 are then placed.
  • the dowels 20 are then placed on the reinforcement mats 16, 17.
  • joint sealing compound 9 is used to form the profile body 7 in the Joint widening 5 introduced, the joint widening 5 being filled with joint sealing compound 9 flush with the surface with the floor slabs 3 and 4.
  • the particular advantage of the joint filling profile according to the invention is that there can be no tears or cracks in the transition area between the profile body 7 and the vertical leg 6 or in the overlapping area of the separating material 8 and reinforcement mats 16, 17, which would then lead to undesirable detachments. Furthermore, the connection-free design of the profile body 7 in the area of the first sections 12 and 13 and the joint 2 creates a comparatively large area in which the joint filling profile 1 can perform free expansion work to compensate for mechanical and / or thermal loads. Undesired detachments and / or flank tears are thus avoided.
  • the vertical limb 6 does not stand in the way of such an expansion work, since according to the invention there is no direct connection between the vertical limb 6 and the profile body 7.
  • Figure 2 shows a further embodiment of the invention in which, in addition to the first separating material 8, a second separating material 22 in the form of an aluminum foil is arranged between the vertical web 6 and the profile body 7.
  • the separating material 22 rests directly on the first separating material 8. In cross section, it ends flush with the first separating material 8.
  • Reinforcing mats 16, 17 are also shown.
  • the reinforcing mat 16 extends over both sections 12, 14.
  • the reinforcing mat 17 extends over the two sections 13, 15.
  • the reinforcing mats 16, 17 are left with one with respect to the image plane in the height direction with the joint 2 aligned gap 21 arranged.
  • the gap 21 is filled with joint sealing compound 9 as part of the profile body 7.
  • the reinforcement mats 16, 17 lie in the first sections 12, 13 directly on the second separating material 22.
  • the arrangement of the first and second separating material 8, 22 on top of one another results in a double layer.
  • the overlapping of the respective reinforcement mat 16, 17 with the double-layer separating material 8, 22 results in a three-layer structure. Due to the multiple layers in certain areas a particularly good force release and absorption within the joint filling profile 1 is achieved. It is therefore particularly insensitive to all possible causes of crack formation.
  • Figure 3 shows a further embodiment of the invention without reinforcement mats 16, 17, in which, in addition to the first separating material 8, a second separating material 22 in the form of an aluminum foil is arranged between the vertical web 6 and the profile body 7.
  • the separating material 22 rests directly on the first separating material 8. In cross section, it ends flush with the first separating material 8.
  • the reinforcement 20 rests directly on the second separating material 22 in the first sections 12, 13.
