Abstract
In a joint strip (1) for sealing joints, in particular of buildings, the joint strip (1) comprises a strip (2) and at least one web (3). At least one holding web (5, 7, 10, 12), which serves for retaining a further sealing means, is arranged on the joint strip (1).
Description
Joint strip Technical field The invention is based on a joint strip as in the preamble of the first claim.
Prior art Joint strips have been known for a long time, for sealing joint structures in the construction sector.
For this, the joint strip is, for example, arranged in the region of the joint to be produced. For sealing, the "outside" joint strip has webs which extend into the region of the adjacent concrete structure or which are bonded into the concrete matrix. In order to make the joint more leakproof or, if water can penetrate around the webs, to seal these subsequently, it is also known that injection tubes can be integrated into the joint strip. However, there is disagreement among experts as to whether tubes integrated during manufacture, e.g. at the top of the web, can fulfill the desired function, and there is an attendant risk, for example, of buckling during rolling of the joint strips with the possibility of a resultant defect.
These molded-on injection tubes are moreover not suitable for ventilation purposes.
An alternative method therefore adopted is subsequent installation, between the webs of the joint strip, of certified injection tubes capable of fulfilling the required function. This is variously achieved with point fixing by metal clips, adhesive bonding for example by hot melt, welding, tapes, lugs, etc.
However, the point fixing generates a risk of positional shift by virtue of the mechanical effects of the concrete, or uncontrolled movement caused by the air present in the tube, reducing the usefulness of the injection tubes. The abovementioned securing methods are moreover very tedious and complicated for users.
Brief description of the invention The invention is based on the object of avoiding the abovementioned disadvantages in a joint strip of the type mentioned in the introduction, and providing a reliable and simple system for securing the injection tubes.
According to the invention, this is achieved by the features of the first claim.
The core of the invention is therefore that at least one retaining web has been arranged on the joint strip and serves for retaining a further sealing means.
The advantages of the invention are inter alia that the entire length of the injection tubes has in essence been fixed, thus eliminating any positional shift during use. The installation of the tubes is very simple, and users cannot make any errors when securing the tubes during installation. The additional webs for securing the tubes moreover improve the functioning of the joint strip, since they increase the distance that water has to travel. The additional costs for the additional webs are minimal, since firstly previous extruder tooling can be adapted very easily and secondly the additional materials costs arising are only minimal.
The dependant patent claims give further advantageous embodiments of the invention.

Only ttube elements essential for fundamental understanding of the invention have been shown.
Methods for carrying out the invention Fig. 1 is a diagram of a joint strip 1 which comprises a strip 2 and a plurality of webs which have advantageously been molded onto the strip 2. The first webs 3 serve to increase the distance that water has to travel, thus sealing the joint. The webs 3 advantageously have projecting parts 4 which serve for more secure placement in the building and serve for sealing because water has to travel a greater distance.
The joint strips are used in a known manner, for example for sealing working joints. These are produced by division of the building into concrete sections, although continuous reinforcement here usually provides a friction-based bond between the sections. Joint strips are usually composed of PVC-P, PVC/NBR, or mod.
PE, or various types of elastomers.
According to the invention, retaining webs 5 have now been arranged on the strip 2 and serve to retain an injection tube of further sealing materials, such as swell strips or the like. In the embodiment of fig. 1, the retaining webs 5 likewise have projecting parts 6, wtube function is the same as that of the projecting parts 4 of the webs 3 but however also serve for reliable retention of the material to be retained. The design of the retaining web 5 and the arrangement on the strip and relative to the webs 3 is in essence dependent on the shape of the tube or material to be retained, in particular from the diameter of the tube, but not on the nature of the tube used. The retaining device can therefore retain any desired injection tubes or materials. The retaining webs 5 advantageously run over the entire length of the joint strip, but can also have been designed so as to be discontinuous, a precondition then being that reliable retention has been provided.
These injection tubes should have a sufficient cross section for good operability, and have sufficient robustness for operations, and discharge of the injection material from the tube system should be possible even at low pressure within the concrete, and the injection system should not bond excessively to the concrete, since otherwise problems can arise when pressure is applied.
Various systems are used as injection tubes. For example, there are perforated round PVC inner tubes with double fabric sheathing, where the fine fabric of the double-fabric sheathing inhibits penetration of wet cement into the interior of the tube during the concreting process (filter function); perforated or slit round PVC inner tubes with slit foam rubber sheathing, with an offset arrangement of the slits in the sheathing with respect to the perforation of the PVC inner tube; perforated round PVC inner tubes with slit foil sheathing, with offset arrangement of the slits in the foil sheathing with respect to the discharge apertures of the inner tube; semicircular or rectangular systems composed of plastics profiles or of rubber profiles with injection channels; slit flat tubes composed of PVC with no additional sheathing, the intention being that the tube slits remain closed under the pressure of the concreting process and do not open until injection pressure is applied, thus inhibiting penetration of wet cement during the concreting process; flat tubes with a plurality of injection channels, where each injection channel can be used separately for an injection procedure (multiple injection). The retaining webs are then naturally adapted to the injection tubes to be used, but in principle a large number of different injection systems can be retained by using this invention.
Examples of injection materials which can be injected into the injection tube are cement suspensions and wet cements, polyurethane resins or polyurethane foams, epoxy resins, acrylic resins, etc.
In fig. 2, a joint strip 1 has been formed with retaining webs of different design, the retaining webs having in essence a similar underlying shape. The retaining web 5 is in essence the same as ttube of fig. 1, and the arrangement has a retaining web 7 which, in comparison with the retaining web 5, is longer and further from the associated web 3. The retaining web 7 can therefore securely retain an injection tube 8 which is larger than the injection tube 9 retained by the retaining web 5. Naturally, it is not usual that two injection tubes are arranged on one joint strip, and the joint strip shown in fig. 2 permits use of injection tubes of different shapes without any requirement for change of the respective joint strip. In the case of relatively wide joint strips, it is naturally also possible to use further shapes of retaining webs, thus permitting retention of still further different injection tubes.
Figs 3 and 4 show another possibility for designing the joint strips with retaining webs, to permit retention of different injection tubes. For this, the retaining webs 5 and 7 have been arranged next to one another, and the shorter web 5 is therefore closer than the longer web 7 to the associated web 3. In fig. 4, a tube 9 with relatively small diameter can then easily be clamped between web 5 and web 3, and the retaining web 7 arranged adjacent thereto here then assumes merely sealing functions. If the intention is to use a tube with relatively large diameter, the web 5 is simply removed and the tube can be retained by means of the web 7.
Figs 5 and 6 show a further inventive form of the retaining webs. One retaining web 10 here is at an inclined angle with respect to the web 3, and fig. 5 shows this in comparison with the web 5 previously shown. In fig. 6, the tube 9 is now easily pushed under the angled web 10 and thus retained by the web. The angle 11 here is selected in such a way that the tube is reliably retained, and that the dependency of the retention system on the shape of the tube has been minimized. The right-hand side of fig. 6 shows that the system shown here can very easily also retain tubes of another shape, since the web 10 is simply bent upward, thus naturally reducing the angle of inclination 11.
Although the web 10 here is almost perpendicular to the strip, the tube 8 is reliably retained, since the web exerts pressure on the tube by means of the resilient force produced by the deformation of the web.
10 The precise shape of the retaining web 10 therefore has to be designed in such a way as to achieve sufficient resilient force as a function of the material used for the strip 1, but that the web 10 does not break away from the strip. The retaining web 10 can naturally also have projecting parts 6 by analogy with the retaining webs 5 and 7, to improve retention.
In fig. 7, retaining webs 12 can also be arranged on the webs 3, at right angles or at an angle 11, here again thus permitting reliable retention of the injection tubes. This arrangement and retention of the injection tubes is analogous to that of fig. 5 and 6, where the arrangement, however, has the retaining webs 10 on the strip 2. The retaining webs 12 here can, by analogy with the retaining webs shown above, have projecting parts 6 or extensions for improved retention of the tubes.
The invention is, of course, not restricted to the inventive example shown and described. By way of example, therefore, the various retaining webs shown can be combined in any desired manner with one another.

The retaining web 5 is in essence the same as ttube of fig. 1, and the arrangement has a retaining web 7 which, in comparison with the retaining web 5, is longer and further from the associated web 3. The retaining web 7 can therefore securely retain an injection tube 8 which is larger than the injection tube 9 retained by the retaining web 5. Naturally, it is not usual that two injection tubes are arranged on one joint strip, and the joint strip shown in fig. 2 permits use of injection tubes of different shapes without any requirement for change of the respective joint strip. In the case of relatively wide joint strips, it is naturally also possible to use further shapes of retaining webs, thus permitting retention of still further different injection tubes.
Figs 3 and 4 show another possibility for designing the joint strips with retaining webs, to permit retention of different injection tubes. For this, the retaining webs 5 and 7 have been arranged next to one another, and the shorter web 5 is therefore closer than the longer web 7 to the associated web 3.

If the intention is to use a tube with relatively large diameter, the web 5 is simply removed and the tube can be retained by means of the web 7.
Figs 5 and 6 show a further inventive form of the retaining webs. One retaining web 10 here is at an inclined angle with respect to the web 3, and fig. 5 shows this in comparison with the web 5 previously shown. In fig. 6, the tube 9 is now easily pushed under the angled web 10 and thus retained by the web.

10 The precise shape of the retaining web 10 therefore has to be designed in such a way as to achieve sufficient resilient force as a function of the material used for the strip 1, but that the web 10 does not break away from the strip. The retaining web 10 can naturally also have projecting parts 6 by analogy with the retaining webs 5 and 7, to improve retention.
In fig. 7, retaining webs 12 can also be arranged on the webs 3, at right angles or at an angle 11, here again thus permitting reliable retention of the injection tubes. This arrangement and retention of the injection tubes is analogous to that of fig. 5 and 6, where the arrangement, however, has the retaining webs 10 on the strip 2. The retaining webs 12 here can, by analogy with the retaining webs shown above, have projecting parts 6 or extensions for improved retention of the tubes.
The invention is, of course, not restricted to the inventive example shown and described. By way of example, therefore, the various retaining webs shown can be combined in any desired manner with one another.
