Description

[0001] The present invention relates to a connection element for arrangement in a connection area between a wall and a ceiling, and to a wall connection with such a connection element. The invention further relates to a method for forming a wall connection between a wall and a ceiling using such a connection element.

[0002] It is common practice to install non-load-bearing interior walls in solid construction, either made of bricks or in the form of wall panels, as partition walls within a building. Such walls generally do not bear the loads of other structural components and are irrelevant to the building's stability. However, they must be able to transfer loads acting upon them to adjacent load-bearing structural elements. These loads can include, for example, lateral impact loads, so-called cantilever loads from objects suspended from the wall, or horizontal forces resulting from earthquakes or explosions.

[0003] When constructing such a partition wall, a joint is created at the ceiling connection between the top of the partition and the ceiling, which is usually filled with mortar. This process is complex, as the joint must be temporarily limited on one side with a tool, such as a board, to allow the mortar to be applied precisely from the other side. Furthermore, when using perforated blocks for the partition wall, the problem arises that the mortar falls through the holes in the blocks. Finally, the mortar is often applied before the individual components have settled sufficiently, which can lead to unintended load transfers and, consequently, cracking in the mortared area.

[0004] The present invention therefore aims to provide a connection element for arrangement in a connection area between a wall and a ceiling, which overcomes the disadvantages of the prior art. A further object of the invention is to provide a wall connection with such a connection element, as well as a method for forming a connection between a wall and a ceiling using such a connection element.

[0005] These tasks are solved by a connection element with the features of claim 1, by a wall connection with the features of claim 8, and by a method for forming a wall connection between a wall and a ceiling with the features of claim 13.

[0006] Specific embodiments and further developments of the invention are the subject of the dependent claims.

[0007] According to claim 1, the invention is a connecting element for arrangement in a connection area between a wall and a ceiling.The connection element according to the invention is characterized in that the connection element is designed as a roof-shaped profile section with a bottom surface and a first and a second roof surface, wherein the profile section comprises an elastic material and has a substantially triangular cross-section in a direction perpendicular to its longitudinal extent with a base and a tip opposite the base, wherein the base is formed by the bottom surface of the profile section and the tip opposite the base is formed by a ridge edge of the profile section formed between the first and the second roof surface, and wherein for a height H determined by the distance between the tip and the base and a width B of the profile section corresponding to the length L of the base, the following applies: B ≥ 5H.

[0008] In other words, the connection element is a roof-shaped profile section which comprises an elastic material and which can be arranged to form a wall connection in a connection area between a wall and a ceiling, in particular between a non-load-bearing interior wall and a ceiling.

[0009] Due to its elasticity, the connection element can accommodate certain settlements and deformations, such as those that frequently occur, particularly in the first few weeks after the completion of a building shell. Furthermore, the elastic connection element provides improved acoustic decoupling between the building components involved. Both of these features offer advantages over simply filling the connection joint with mortar.

[0010] The profile section according to the invention comprises a substantially flat underside and two surface sections forming an upper surface and enclosing an obtuse angle with each other, which, in accordance with the roof-like shape of the profile section, are referred to as the first and second roof surfaces. The first and second roof surfaces adjoin each other, forming a ridge edge.

[0011] In a direction perpendicular to its longitudinal extent, the profile section has a substantially triangular cross-section with a base and a point opposite the base, the base being formed by the underside of the profile section and the point opposite the base by the ridge edge of the profile section. The ridge edge and the point formed by it may be slightly rounded, for example, for manufacturing reasons. For a height H defined by the distance between the point and the base and a width B of the profile section corresponding to the length of the base, the following applies: B > 5H. In other words, the profile section is significantly wider than it is tall.

[0012] For example, the width of the profile section can be between 80 mm and 150 mm, while the height of the profile section can be approximately 12 mm to 16 mm. The width of the profile section is preferably determined by the depth of the wall to be connected. Generally, the width of the profile section is slightly less than the depth of the wall.

[0013] The connection element according to the invention is intended for placement in a connection area between a wall and a ceiling, for example between the top of a masonry partition wall and a ceiling, in order to at least partially close an existing connection joint. Various options exist for aligning and fixing the connection element in the connection area, which will be explained in more detail below.

[0014] In principle, gaps and joints remaining between the wall, the ceiling, and the connecting element located between the wall and ceiling can be subsequently filled with mortar. The connecting element according to the invention offers the advantage that, due to the roof-like geometry of the profile section, the gap to be filled is directly defined, thus eliminating the need for an additional aid, such as a board held laterally against the joint. This simplifies and accelerates the mortaring process. In particular, it is possible to fill the gaps with mortar only after any settlement has largely subsided, thereby significantly reducing the risk of cracking.

[0015] According to one embodiment of the connecting element according to the invention, the profile section comprises at least one side surface oriented longitudinally along the profile section, which extends substantially at right angles to the underside between the underside and a roof surface. In other words, the cross-section may deviate slightly from a pure triangular shape, such that either one or both lateral points are blunted or truncated. In the case of a blunt lateral point, the corresponding roof surface of the profile section does not extend directly to the underside; rather, the profile section in this case comprises a side surface that extends between the underside and the outer edge of the roof surface. According to the invention, this side surface forms a right angle with the underside.

[0016] According to the invention, the essentially triangular cross-section of the profile section includes both triangular cross-sections and cross-sections that deviate slightly from the triangular shape in the manner described above.

[0017] A profile section with a cross-section that deviates slightly from the triangular shape, in that the lateral points are blunted in the manner described above, has the advantage of better pressure distribution in the case of loads acting laterally on the wall compared to a profile section with a purely triangular cross-section.

[0018] One embodiment of the invention provides that the ratio of the height h of the side surface to the height H of the profile section is: h / H ≤ 0.5.

[0019] According to one embodiment, the profile section is mirror-symmetrical with respect to a mirror plane. The mirror plane can preferably be oriented such that it extends perpendicular to the underside of the profile section and the ridge edge formed between the roof surfaces lies in the mirror plane. Alternatively, the profile section can also be designed asymmetrically, for example, to accommodate the geometry of a specific wall connection.

[0020] According to the invention, the profile section comprises an elastic material. This can be, for example, a material based on rubber, polyurethane, or other elastomers. The material used can be partially or completely recycled. The elastic material can also be based on renewable raw materials.

[0021] The profile section can be produced, for example, by peeling it from suitable sheets and strips or by casting or pressing a flowable material into appropriate molds. The strength or flexibility of the elastic material can be adjusted by controlling the porosity. The profile section can be solid. Solid in this context means that while the material may contain pores, the profile section does not have any additional cavities whose dimensions significantly exceed those of individual pores.

[0022] It may be provided that the profile section is made entirely of an elastic material.

[0023] Alternatively, the profile section can be designed to include a non-woven material. This non-woven material can be arranged in such a way that it forms at least part of the profile section's surface. Such a non-woven material is characterized by its good adaptability, as it can compensate for unevenness in the concrete or the surface of masonry units. Furthermore, as described below, it can facilitate the fixing of the profile section in the connection area using mortar.

[0024] The nonwoven material can be directly embedded in the elastic material, eliminating the need for subsequent bonding between the two. This also eliminates the need for additional materials, such as adhesives, which is advantageous both in terms of fire safety regulations and the recyclability of individual components. The bond between the nonwoven and elastic materials prevents the two components from shifting relative to each other under load.

[0025] According to one embodiment of the invention, the nonwoven material can be incorporated into the elastic material in such a way that it forms the underside of the profile section. To fix such a profile section equipped with nonwoven material in a connection area between a wall and a ceiling, the underside of the profile section, formed by the nonwoven material, can first be coated with mortar. The mortar settles in small pores and cavities in the nonwoven material and thus adheres securely to it. The profile section can then be glued to the top of the wall or ceiling using the mortar. The nonwoven material ensures a particularly high shear load-bearing capacity of the connected components.

[0026] In principle, it is also possible for the fleece material to be embedded in the elastic material in the area of ​​the roof surfaces of the profile section, forming a top surface of the profile section. Finally, the fleece material can also be embedded in the elastic material in such a way that it forms both the underside and the top surface of the profile section.

[0027] The connection element according to the invention is particularly suitable for connecting a wall to a ceiling. However, the connection element is also fundamentally suitable for connecting one wall to another, especially for connecting a non-load-bearing wall to a load-bearing wall.

[0028] According to claim 8, the invention also relates to a wall connection between a wall and a ceiling, wherein the wall connection comprises a connection element according to any one of claims 1 to 7. In such a wall connection, a connection element according to any one of claims 1 to 7 is thus arranged in a connection area between a wall, in particular a non-load-bearing interior wall, and a ceiling, thereby at least partially closing the connection joint existing in the connection area. Due to its elasticity, the connection element can accommodate certain settlements and deformations, such as those that frequently occur, particularly in the first few weeks after the construction of a building shell. This represents an advantage over completely filling the connection joint with mortar.

[0029] It can be provided that the wall connection includes mortar in addition to the connection element. In particular, it is possible that, in a first step, the connection element is positioned in the connection area as described above, so that the connection joint is already at least partially closed, and only subsequently, in a second step, after any settlement has substantially subsided, are remaining joints between the connection element, the wall, and the ceiling filled with mortar. This temporal decoupling between the step of at least partially closing the connection joint using the connection element according to the invention and the step of subsequent mortar filling can significantly reduce the tendency for cracking in the wall connection.

[0030] The roof-like shape of the profile section offers the further advantage that the mortar can be applied to the remaining gaps particularly easily and quickly, without the need for an aid, such as a board, to temporarily limit the joint laterally.

[0031] In particular, it can also be provided that, when using a profile section comprising a non-woven material to form the wall connection, mortar is first applied to the underside of the profile section formed by the non-woven material, and the profile section thus coated with mortar is positioned in the connection area and fixed with the mortar before the remaining joints or gaps between the connection element, the wall, and the ceiling are filled with mortar at a later time. With this design of the wall connection, the connection element is thus essentially completely embedded in mortar. An advantage of the non-woven material is that it has small pores and spaces in which the mortar can settle, allowing it to adhere to the non-woven material.In particular, a profile section coated with mortar in this way can easily be applied to the top of a partition wall constructed of perforated bricks without the risk of mortar falling through the holes in the bricks, as it adheres sufficiently strongly to the fleece material. At the same time, the profile section covers the holes in the perforated bricks in such a way that even when the remaining gaps and joints between the wall, ceiling, and connecting element are subsequently mortared, no mortar can fall through the holes.

[0032] The mortar can be standard mortar and / or thin-bed mortar. It may contain cement. In particular, the mortar can also be clay-based. Clay-based mortar has the advantage of being water-soluble, meaning that a wall connection made with clay-based mortar can be dismantled separately, and in particular, the connection element can be removed from the connection area and reused or recycled. This is advantageous with regard to sustainable construction.

[0033] According to one embodiment of the wall connection, the connecting element is positioned between the wall and the ceiling such that the ridge edge of the profile section faces the ceiling. In other words, the flat underside of the profile section faces the top of the wall and rests on it either directly or with an intervening layer of mortar. As described above, such an arrangement is particularly suitable when the wall is constructed of hollow bricks.

[0034] In an alternative design for the wall connection, the connecting element is positioned between the wall and the ceiling such that the ridge edge of the profile section faces away from the ceiling. In other words, in this design variant, the profile section rests against the ceiling with its underside, possibly with a layer of mortar in between.

[0035] In this design, the wall connection can also be configured such that a wedge-shaped recess, corresponding to a negative form of the connection element, is formed in the upper surface of the wall, in which the connection element is at least partially received. This type of wall connection is particularly suitable for connecting partition walls constructed from wall panels, such as full-height aerated concrete panels. To create the wall connection, the connection element can simply be inserted into the recess formed in the upper surface of the wall panel or, if necessary, stapled to the wall panel in this position. Subsequently, as described above, any remaining gaps and joints between the upper surface of the wall panel, the connection element, and the ceiling can be filled with mortar.

[0036] Finally, the invention according to claim 13 also relates to a method for forming a wall connection between a wall and a ceiling, comprising the following steps: Providing a connection element according to one of claims 1 to 7; arranging the connection element in a connection area between a top surface of the wall and the ceiling.

[0037] In its simplest embodiment, the method thus comprises only the steps of providing and arranging a connection element according to the invention in a connection area between the top of a wall and a ceiling, wherein the connection element is preferably inserted between the wall and the ceiling in such a way that there is initially a certain amount of play between the ridge edge of the profile section and the ceiling or the wall with regard to possible settling.

[0038] According to one embodiment, the method according to the invention comprises the additional step of applying mortar to the underside of the profile section before the connecting element is positioned in the connection area between the top of the wall and the ceiling. The connecting element can be applied with its underside either to the top of the wall or to the ceiling.

[0039] According to another variant, the procedure includes the additional step of filling joints existing between the top of the wall, the ceiling and the connecting element with mortar, for example with normal mortar and / or with thin-bed mortar, in particular with a clay-bound mortar.

[0040] In one embodiment of the method, it may also be provided that a wedge-shaped recess, corresponding to a negative form of the connecting element, is first formed in the upper surface of the wall, in particular a wall made of a wall panel, into which the connecting element is then inserted. Subsequently, existing joints between the upper surface of the wall, the ceiling and the connecting element can be mortared.

[0041] The invention will now be explained in more detail using an exemplary embodiment and with reference to the accompanying figures. These show: Figure 1: an embodiment of a connection element according to the invention in perspective view; Figure 2: the connection element made of Figure 1Figure 3: an embodiment of a wall connection according to the invention in a sectional view; Figure 4: an alternative embodiment of a wall connection according to the invention in a sectional view.

[0042] Figure 1 Figure 1 shows a section of a connection element according to the invention, which is designated in its entirety by 1. The connection element 1 is intended for arrangement in a connection area between a wall 2 and a ceiling 3, as is the case, for example, with Figure 3 As can be seen, wall 2 is a non-load-bearing interior wall constructed of masonry, which is to be connected to the concrete ceiling 3 by closing a connection joint 16 existing between the top of wall 2 and the ceiling 3. For this purpose, the connection element 1 is positioned in the connection area, as explained in more detail below.

[0043] The connecting element 1 is designed as a roof-shaped, mirror-symmetrical profile section 4 with a bottom surface 5 and a first roof surface 6 as well as a second roof surface 7. The two roof surfaces 6, 7 meet at an obtuse angle and form a ridge edge 10 between them. In a direction perpendicular to its longitudinal extent indicated by the arrow L, the profile section 4 has a substantially triangular cross-section with a base 8 and a point 9 opposite the base 8, which is particularly evident from the Figure 2 This is evident. The base 8 is formed by the underside 5 and the tip 9 by the ridge edge 10 of the profile section 4.

[0044] In its two lateral edge regions, the cross-section deviates slightly from the triangular shape, such that the two lateral points are truncated. Starting from the underside 5 of the profile section, two lateral surfaces 11 and 12 of the profile section 4 extend here essentially at right angles to the underside 5 and along the length of the profile section 4, cf. Figure 1 The two roof surfaces 6, 7 therefore do not directly abut the underside 5 of the profile section 4; rather, the side surfaces 11, 12 extend between a roof surface 6, 7 and the underside 5.

[0045] For a height H of profile section 4, determined by the distance between the apex 9 and the base 8, and a width B of profile section 4, determined by the length of the base 8, the following relationship holds: B > 5H. Profile section 4 is therefore significantly wider than it is tall, so that the [missing information] in the Figure 2The cross-section of profile section 4 shown appears essentially triangular despite the blunted side areas. The following applies to the height h of the side surfaces 11, 12 and the height H of profile section 4: h / H ≤ 0.4.

[0046] Specifically, the width B of the [unclear text] is [unclear text] Figures 1 to 3 In the illustrated embodiment of profile section 4, the height is approximately 115 mm, while the height H is approximately 16 mm and the height h of the side surfaces 11, 12 is approximately 6 mm.

[0047] The tread section 4 is essentially made of an elastic rubber material obtained from recycled motor vehicle tires. Additionally, the tread section 4 includes a nonwoven material 13, which forms the underside 5 of the tread section 4. The nonwoven material 13 was incorporated into the rubber material during the manufacturing process of the tread section 4 in such a way that it is firmly bonded to it without any further bonding agents.

[0048] Figure 1 shows only a short section of a connection element 1. The profile section 4 can, in principle, be provided in any length and its length can be adapted to the length of a wall 2 to be connected.

[0049] Figure 3 Figure 1 shows a sectional view of a wall connection 14 between a wall 2 and a ceiling 3, which includes such a connection element 1. In addition to the connection element 1, the wall connection 14 includes a clay-bound mortar 15, with which existing gaps and joints between the connection element 1, the wall 2 and the ceiling 3 are filled.

[0050] The connecting element 1 is positioned between the wall 2 and the ceiling 3 such that the ridge edge 10 of the profile section 4 faces the ceiling 3 and the underside 5 of the profile section 4 faces the wall 2. To form the wall connection 14, mortar 15 is first applied to the underside 5 of the profile section 4, which is formed by the fleece material 13, before the profile section 4, thus coated with mortar 15, is placed on the top of the wall 2. The layer of fleece material 13 can compensate for minor irregularities in the wall material. It also ensures that the mortar 15 adheres particularly well to the profile section 4, allowing it to be securely bonded to the wall 2. In particular, even with a wall 2 constructed of perforated bricks, there is no risk of significant amounts of mortar 15 falling through the holes in the bricks.At the same time, these holes are covered by the attached connecting element 2 in such a way that even when mortar 15 is introduced into the gaps and joints between wall 2, ceiling 3 and connecting element 1 as described below, no mortar 15 can fall through the holes.

[0051] The steps of inserting the connection element 1 into the connection area between wall 2 and ceiling 3 and the step of applying mortar 15 into the remaining gap can preferably be decoupled in time. In other words, to form the wall connection 14, the connection element 1 can first be inserted into the connection area and bonded to the wall 2 using mortar 15 applied to the fleece material 13. In this way, the connection joint 16 between the top of the wall 2 and the ceiling 3 is already partially closed. In particular, due to its elastic properties, the connection element 1 can subsequently accommodate certain settlements of the components involved.

[0052] Once such settlements have largely subsided after a certain period, for example, after a few weeks, mortar 15 can be applied to the remaining gaps and joints between the top of the wall 2, the ceiling 3, and the connecting element 1 to completely seal the connection joint 16. Due to its special, roof-like geometry, the profile section 4 acts as a boundary for each gap to be filled, eliminating the need for an additional aid, such as a board held against the side of the connection joint 16. The gaps can be filled conveniently and quickly from both sides of the wall 2. It is particularly advantageous that the mortar 15 is only applied once any settlements have largely subsided. This type of force-fit mortaring significantly reduces the risk of cracking in the area of ​​the wall connection 14.

[0053] Finally, the connecting element 1, which comprises an elastic material, contributes to improved acoustic decoupling between the wall 2 and the ceiling 3.

[0054] Figure 4 Figure 1 shows an alternative embodiment of a wall connection 14 according to the invention between a wall 2 and a ceiling 3. The difference to the one in the Figure 3 The wall connection 14 shown consists only in the fact that the connection element 1 is arranged here in the reverse installation direction between the wall 2 and the ceiling 3, so that the ridge edge 10 of the profile section 4 faces the wall 2 and the underside 5 of the profile section 4 faces the ceiling 3.

[0055] To form the wall connection 14 thus created, mortar 15 is first applied to the underside 5 of the profile section 4, which is formed by the fleece material 13, before the profile section 4, coated with mortar 15, is placed on the ceiling 3. The layer of fleece material 13 can compensate for minor irregularities in the ceiling material. It also ensures that the mortar 15 adheres particularly well to the profile section 4, allowing it to be securely bonded to the ceiling 3. As already mentioned above in connection with the Figure 3 As described, mortar 15 can subsequently be injected into the remaining gaps and joints between the top of the wall 2, the ceiling 3 and the connecting element 1 in order to completely close the connecting joint 16.
