DETAILED DESCRIPTION

(5) In order to achieve the effect according to the invention, it is only necessary that either a second separating material or a reinforcing mat are provided in addition to the to the first separating material in the manner according to the invention. The combination of both features and all the other preferred features are optional, but contribute to the further improvement of the invention both on their own and in synergetic combination.

(6) FIG. 1 shows a joint filling profile 1 according to the invention. A joint 2 is left between two adjacent floor slabs 3 and 4, for example an expansion joint. This usually results from building regulations or other necessities. In the area of the joint 2, a filling material 10, e.g. a form insert, and a round cord 11 are arranged in a manner known per se in order to prevent three-flank adhesion. Otherwise, the joint sealing compound would connect the floor slabs 3 and 4 as well as the underlying ground with each other.

(7) In the area of the mutually facing free upper edges of the floor slabs 3 and 4, an essentially horizontally extending joint widening 5 is formed, which defines rectangular grooves on the outside which essentially run parallel to the joint 2.

(8) To form the joint filling profile 1, the joint 2 is filled with joint sealing compound 9 as far as the joint widening 5 and flush with the surface. The joint filling profile 1 has a vertical leg 6 arranged in the joint 2 and a profile body 7 arranged in the joint widening 5. The vertical leg 6 and the profile body 7 of the joint filling profile 1 are not formed in one piece, but rather separated from each other. This is achieved by arranging a separating material 8 between the vertical leg 6 and the profile body 7. The separating material 8 can, for example, be a mechanically acting intermediate layer, for example a metal foil, in particular an aluminum foil. In the design example shown, the vertical leg 6 and the profile body 7 are formed from a joint sealing compound 9. The same sealing compound 9 is preferably used for both the vertical leg 9 and the profile body 7. Alternatively, the vertical leg 6 can be designed as a compression block made of an elastic material such as a foam material. In any case, however, it is provided that the vertical leg 6 and the profile body 7 are separated from each other by means of the separating material 8, so that there is no direct connection between the profile body 7 and the vertical leg 6.

(9) For each base plate 3 or 4, the profile body 7 provides a first portion 12 or 13 adjacent to the joint 2 or the vertical web 6, in which first portion 12 or 13 the profile body 7 rests on the associated base plate 3 or 4 in a connection-free manner with a separating material 8 in between. This creates a continuous area that extends over the first portion 12 formed in the area of the base plate 3, the joint 2 and the first portion 13 formed in the area of the base plate 4, in which there is no direct connection between the profile body 7 and the substrate.

(10) The profile body has second portions 14 or 15 adjacent to the first portions 12 or 13. In the area of these portions 14 or 15 there is a third connection between the joint sealing compound 9 forming the profile body 7 and the substrate formed by the respective floor slabs 3 and 4.

(11) Within the profile body 7, a reinforcing mat 16, 17 of lattice-like longitudinal and transverse struts is arranged on both sides of the joint 2 above the separating material 8 with reference to the image plane. The reinforcing mat 16 extends over both portions 12, 14. The reinforcing mat 17 extends over both portions 13, 15. The reinforcing mats 16, 17 are arranged leaving a gap 21 aligned with the joint 2 in height direction with respect to the image plane. The gap 21 is filled with joint sealing compound 9 as part of the profile body 7. The arrangement of the reinforcing mats 16, 17 according to the invention ensures that the crack formation in the portions 14, 15 adjacent to the separating material, which is a disadvantage in prior art, is prevented in an advantageous manner. Due to their lattice-like structure, the reinforcing mats 16, 17 have openings formed between longitudinal and transverse struts that are continuous for the joint sealing compound 9. In portions 14, 15, the reinforcing mats 16, 17 each rest on spacers 18, 19. Overall, this ensures that the joint sealing compound 9 of the profile body 7 in the portions 14, 15 is in contact with the respective floor slabs 3, 4. Each spacer 18 or 19 can have a bearing element extending in the longitudinal direction of the joint which is supported by supporting elements. The profile body 7 is thus largely free of stresses between the joint sealing compound 9 and the floor slabs 3, 4.

(12) Furthermore, reinforcements in the form of plugs 20 are arranged inside the profile body 7. The reinforcements are optional in this as well as in the other embodiments according to FIGS. 1 to 3. With regard to the reinforcements, a large number of plugs 20 are provided, which are arranged one behind the other in the longitudinal direction of the joint 2. The plugs 20 are preferably positioned at equal distances adjacent to each other. Each plug 20 has a sleeve and a rod which is held by the sleeve. A sleeve is longer in its longitudinal extension than the associated rod, i.e. the longitudinal extension of the sleeve exceeds the longitudinal extension of the corresponding rod. This design makes it possible for the rod to move relative to the sleeve.

(13) In the example shown, the two spacers 18, 19, which support the plug 20 at one end or at the other end, are used to position the plug 20 securely within the joint widening 5. In the present embodiment, the reinforcing mats 16, 17 are arranged between the plugs 20 and the spacers 18, 19. The plugs 20 rest on the reinforcing mats 16, 17 at least in the area of both sides.

(14) It is further provided that the extension of the reinforcing mats 16, 17 at the ends of each of the portions 14, 15 exceeds the longitudinal extension of the plugs 20. It has been shown that this can prevent edge cracking at the end of the plugs.

(15) To form the joint sealing, the filling material 10 and the round cord 12 are first introduced into joint 2. Then the vertical leg 6 is formed, in the example shown, by introducing the joint filling compound 9 into the joint 2, whereby the joint 2 is filled at least flush with the surface of the bottom of the joint widening 5. It cannot be excluded that part of the vertical leg 6 projects into the joint widening 5. Nevertheless, the vertical leg 6 and the profile body 7 are completely separated from each other by the separating material 8. The respective joint-side end of the reinforcing mats 16, 17 can rest on the part of the vertical leg 6 projecting into the joint widening 5, with the separating material 8 being interposed. It is preferable that the combined height of the part of the vertical leg 6 projecting into the joint widening 5 and of the separating material 8 corresponds to the height of the spacers 18, 19. This ensures that the reinforcing mats 16, 17 are aligned horizontally in the joint widening 5. This results in stress absorption on the part of the reinforcing mats 16, 17 which is particularly homogeneous.

(16) Then the separating material 8 is introduced, which in the example shown extends over the joint 2 and the two first portions 12 and 13 of the floor slabs 3 and 4 respectively. The spacers 18 and 19 are then positioned within the joint widening 5, onto which the reinforcing mats 16, 17 are then placed. Thereafter, the plugs 20 are placed on the reinforcing mats 16, 17. Then the joint filling compound 9 is introduced into the joint widening 5 to form the profile body 7, with the joint widening 5 being filled with the joint sealing compound 9 so as to be flush with the surface of the floor slabs 3 and 4.

(17) A particular advantage of the joint filling profile in accordance with the invention is that neither in the transition area between the profile body 7 and the vertical leg 6 nor in the overlap area of the separating material 8 and the reinforcing mats 16, 17 tearing or cracking can occur which would then lead to undesirable detachments. Furthermore, the connection-free design of the profile body 7 in the area of the first portions 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. Unwanted detachments and/or flank breaks are thus avoided. The vertical leg 6 does not stand in the way of such an elongation work either, since according to the invention there is no direct connection between the vertical leg 6 and the profile body 7.

(18) FIG. 2 shows another 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 lies directly on the first separating material 8. It is flush with the edges of the first separating material 8 in cross section.

(19) Also shown are reinforcing mats 16, 17. The reinforcing mat 16 extends over both portions 12, 14. The reinforcing mat 17 extends over both portions 13, 15. The reinforcing mats 16, 17 are arranged leaving a gap 21 aligned with the joint 2 in the direction of height with respect to the image plane. The gap 21 is filled with joint sealing compound 9 as part of the profile body 7.

(20) In the first portions 12, 13, the reinforcing mats 16, 17 rest directly on the second separating material 22.

(21) In the area of the gap 21, the arrangement of the first and second separating materials 8, 22 on top of each other results in a double layer. In the first portion, on the other hand, the overlapping of the respective reinforcing mat 16, 17 with the double-layer separating material 8, 22 results in a three-layer structure. Due to the multiple layers in some 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.

(22) FIG. 3 shows a further embodiment of the invention without reinforcing 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 lies directly on the first separating material 8. It terminates flush with the edges of the first separating material 8 in cross section.

(23) In this embodiment, the reinforcement 20 in the first portions 12, 13 rests directly on the second separating material 22.

(24) In particular, the double-layer arrangement of the two separating materials 8, 22 allows a more extensive decoupling of the profile body and vertical web in terms of movement compared to the prior art. This is particularly because the first separating material 8 only has contact with the vertical web 6, but not with the profile body. On the other hand, the second separating material 22 only has contact with the profile body, but not with the vertical web. In the event of expansion movements, the two separating materials 8 and 22, which are designed as aluminum foils, can slide over each other completely freely and almost without frictional resistance. In contrast to prior art, in which only one separating material is provided and in which adhesion can take place on both sides, adhesions of joint sealing compound to the foils 8, 22 have no consequences.
