Abstract

  In particular, in a water stop plate (1) for sealing a seam of a building, the water stop plate (1) comprises one sheet (2) and at least one web (3). The water stop plate (1) is provided with at least one holding web (5, 7, 10, 12) for holding further sealing means.

Description

  The present invention relates to a water stop plate described in the description of the first claim.

Waterstops have long been known for sealing seam structures in the construction field. For this purpose, the water stop plate is arranged, for example, in the region of the seam to be built. The water stop plate provided for the so-called outer wall for sealing is provided with a plurality of webs that protrude into the area of the adjacent concrete structure or that are bonded to the concrete matrix. It is also known to incorporate an injection hose into the waterstop to improve the sealability of the seam or to seal the web later if water penetrates the web. However, among experts, there is a discussion about the functional eligibility of the hose incorporated in the head part of the web at the factory side, for example, there is a risk of bending when winding the water stop plate, and consequently the defective part There is a possibility. Furthermore, an injection hose made in that way is not suitable for air discharge purposes.
As an alternative, a function-qualified, approved injection hose is later installed between the webs of waterstops. Each of these is done by point-by-point fixation using metal clips such as hot melt bonding, welding, tape, links. However, with point-by-point fixing, there is a risk of misalignment due to mechanical effects of the concrete or due to air floats contained in the hose, thereby causing the injection hose to partially fail. Furthermore, the above-described fixing method is expensive and complicated for the user.

  An object of the present invention is to provide a more reliable and simple fixing system for an injection hose by avoiding the above-mentioned disadvantages of the water stop plate as described above.

  This problem can be solved by the features of the first claim of the present invention.

  The core of the present invention is that at least one holding web for holding a further sealing means is arranged on the water stop plate.

  The advantages of the present invention are in particular that the pouring hose is fixed over substantially the entire length so that the position does not shift during use. The hose installation is very simple and the user does not make any mistakes in fixing the hose during installation. The function of the water stoppage is improved because the waterway is raised by the additional web for fixing the hose. The additional cost for the additional web is kept to a minimum because it is very easy to adapt a conventional extrusion tool and the additional material cost is minimal.

  Further preferred embodiments of the invention can be taken from the dependent claims.

Hereinafter, embodiments of the present invention will be described in detail with reference to the drawings. In these figures, the same elements are denoted by the same reference numerals.
Only the important elements necessary for a direct understanding of the invention are shown.

  FIG. 1 shows a water stop plate 1 having a sheet 2 and a plurality of webs suitably formed on the sheet 2. The first web 3 raises the water channel, thereby sealing the seam. The web 3 is preferably provided with protrusions 4 for better fixing to the structure and for improving sealing by increasing the ease of water flow. The water stop plate is used in a known manner, for example, for sealing a seam. The joint line is generated when the structure is divided into a plurality of concrete placing segments. However, since the reinforcing bars penetrate, the plurality of segments are usually connected in a frictional connection. The material of the waterstop is usually PCV-P, PVC / NBR, modified PE (mod. PE), various elastomers.

  In the sheet 2, a holding web 5 according to the invention is arranged for holding a further sealing material such as an injection hose or a water-swellable sealing band or the like. In the embodiment according to FIG. 1, the holding web 5 is similarly provided with a protruding portion 6, which has the same function as the protruding portion 4 of the web 3, but additionally holds down the material to be held. There is also a role to keep. The configuration of the retaining web 5 and the relative arrangement with respect to the web 3 on the seal depends largely on the material to be retained or the geometry of the hose, in particular the hose diameter, but depends on the type of hose used. do not do. This is because the holding device can hold any injection hose or material. The holding web 5 preferably extends over the entire length of the water blocking plate, but can also be constituted discontinuously if the condition that stable holding is ensured is satisfied.

  What is required for the injection hose is that the injection hose has a sufficient cross-section for good processability, is durable for processing, and is injected from the hose system when embedded in concrete. The injection system must not be too tightly coupled with the concrete because it is necessary to be able to do this already at low pressure when injecting, and problems may occur during the injection.

Many different systems are used as injection hoses. Examples include the following: A perforated, round PVC inner hose with a double woven casing that allows cement paste to get inside the hose during concrete casting. Avoided by fine weaving of double woven casing (filter function); round PCV inner hose with holes or slits, with slit micro-cellular rubber casing The casing slit is arranged with a position shifted from the hole of the PCV inner hose; a perforated PCV inner hose with a slit-fitted film casing, The slits are offset from the outlet openings of the inner hose; A semi-circular or rectangular system composed of a plurality of plastic or rubber moldings with a number of injection ducts; a slitted PVC flat hose without a casing, the slit of the hose To prevent cement paste from entering the concrete, it remains closed under concrete pressure and needs to be opened for the first time by injection pressure; a flat hose with multiple injection ducts, each injection duct separately What can be used for one injection step (multiple injection). In this case, of course, the holding web is adapted according to the injection hose used, but basically a number of different injection systems can be held according to the invention.
Examples of the injection material that can be injected into the injection hose include cement suspension and cement paste, polyurethane resin or polyurethane foam, epoxy resin, and acrylic resin.

  FIG. 2 shows a waterstop 1 with various shapes of retaining webs, which have substantially similar basic geometric shapes. The holding web 5 substantially corresponds to the holding web 5 of FIG. 2, and the holding web 7 is longer than the holding web 5 and is arranged farther from the assigned web 3. Thereby, the holding hose 7 can be used to reliably hold the injection hose 8 larger than the injection hose 9 held by the holding web 5. Of course, normally, two injection hoses are not arranged on one water stop plate, but the water stop plate shown in FIG. 2 can use injection hoses with different geometric shapes. There is no need to replace the waterstop. In the case of wider waterstops, other geometric shaped retention webs can be used, thereby further holding various injection hoses.

  FIGS. 3 and 4 show further possibilities for the construction of waterstops with retaining webs for holding various injection hoses. To that end, the holding webs 5 and 7 are arranged adjacent, so that the shorter web 5 is closer to the assigned web 3 than the longer web 7. According to FIG. 4, the hose 9 having a smaller diameter can simply be sandwiched between the web 5 and the web 3, and the holding web 7 arranged adjacent thereto bears in this case only the sealing function. . If a hose with a larger diameter is used, the web 5 can simply be removed and the hose can be held by the web 7.

  5 and 6 illustrate further shapes of the retaining web according to the present invention. Here, the holding web 10 is inclined at a predetermined angle 11 with respect to the web 3, and is shown in FIG. 5 in contrast to the web 5 previously illustrated. According to FIG. 6, the hose 9 is simply pushed under the inclined web 10 and held in that state. The predetermined angle 11 is chosen to ensure that the hose is held at this time and that the holding system is as independent of the hose geometry as possible. On the right side of FIG. 6, the web 10 is easily bent upwards, thereby reducing the angle of inclination 11, so that the other hose shapes can be held very easily using the system shown in this figure. It has been shown that it can. In this figure, the web 10 is disposed substantially perpendicular to the sheet. However, the web 10 is pressed against the hose by the repulsive elastic force generated by bending the web, so that the hose 8 is securely held. Therefore, the accurate geometric shape of the holding web 10 needs to be configured so that a sufficient rebound resilience is obtained according to the material used for the sheet 1 and the web 10 does not break from the sheet. In order to improve the holding force, the holding web 10 can be provided with a protruding portion similar to the holding web 5 and the holding web 7.

  As shown in FIG. 7, the holding web 12 can also be arranged on the web 3, and the holding web can be arranged at a right angle or a predetermined angle 11. This arrangement and holding of the injection hose is performed in the same manner as in FIGS. 5 and 6, but in FIGS. 5 and 6, the holding web 10 is arranged on the sheet 2. Similar to the holding web described above, the holding web 12 can be provided with a protruding portion 6 or an extended portion in order to improve the holding force of the hose.

  The invention is of course not limited to the embodiments shown and described. Thus, for example, the various holding webs shown can be arbitrarily combined with each other.
