vibration-proof seal for driving terraces "

The invention aims to seal terraces of any height on which motor vehicles can travel. It can act here to park terraces or, in general, to any driving surface arranged in terraces.

The waterproofing made from one to the junction between The floor and wall of the terrace is made up of strips to ensure water tightness and therefore against the Shocks caused by vehicles, which could lead to cracking, be insensitive.

It is known to produce a vibration-resistant seal by the following process steps in place to be carried out:

809828/0759

1. Application of a sealing layer made of a standardized material, usually reinforced bitumen 40 (40 kg per 10 m ² ), which is usually applied in two layers, which in turn are reinforced with a support bracket made of reinforced bitumen in a width of 0.20 m.

2. Build-up of a protective layer of cement mortar with a grid or reinforced, depending on the circumstances (before sealing attached welded mesh or wire mesh; Thickness of the layer at least 3 cm).

The seal produced in this way must, in addition to being watertight also have a resistance to all vibrations caused by vehicle traffic.

Apart from the disadvantage that a considerable amount of time is required for its production process, which comprises several successive process steps, the actual sealing layer hardly presents any problems. This is not true for the cement layer, resulting from the following disadvantages:

a) The attachment is problematic,

b) the sealing layer is covered by the cement layer, which makes it difficult to find any leaks that may result from the detachment of the sealing layer,

c) There is a risk of perforation, damage or being carried away to the sealing layer in the event of a defective one Fixing the cement layer, which allows water to penetrate behind the waterproofing layer,

d) the appearance is impaired by the formation of cracks in the mortar,

e) repairs are difficult and expensive,

f) if leaks occur, the entire cement layer must be completely removed and renewed,

809828/0759

g) the production requires a high expenditure of time and money, h) in general it will be necessary to underlay the surface to post-treat aesthetic aspects, e.g. by painting.

Furthermore, the described production of the seal in several process stages on the construction site is tedious, and so is the case more than it can be interrupted and delayed by unfavorable weather conditions (in bad weather conditions several days required). For all of the reasons mentioned, the production is very expensive.

The invention is therefore based on the object of avoiding the disadvantages described.

This object is achieved according to the invention by a method for producing a vibration- ^{resistant A T} xlinge of the type mentioned above, which is characterized in that a strip of a one-piece, prefabricated material is applied to the connection point between the floor and the wall of the terrace in a single process step , which consists of a flexible bitumen covering on a glass reinforcement, the surface of which is protected by a foil made of stainless steel.

The strip is preferably applied by known welding, ie by melting the bitumen, which causes the strip to adhere to the floor and to the wall, the junction of which is to be sealed so that it is particularly resistant to vibrations. The application can also be carried out by gluing with any suitable layer, which is known per se for applying a covering of reinforced bitumen under the action of heat.

809828/0759

With the method according to the invention, in a single method step a watertight seal that is insensitive to vibrations is achieved, compared to the known Vibration-resistant seals have the following advantages:

1. Application is easy.

2. Significant time savings are achieved in the production of the seal, which means the dependency on the Weather conditions is considerably degraded.

3. Errors in the application and subsequent damage can be found immediately thanks to the one-piece nature of the material.

4. Repairs are easy and inexpensive to carry out by looking at the damaged area in a shape and size fitting piece is welded on after it has been cut out of the strip-shaped material described.

5. The prime costs of the waterproofing are significantly lower.

6. Resistance is great in all points examined thanks to the stainless steel foil; in particular exists excellent shock resistance and great insensitivity to most aggressive ones chemicals in the air, including salt spray.

7. The manufacturing technique of the material, which is known per se, but only for use in corrosion protection, is tried and tested.

8. The external appearance of the seal can vary be: The already decorative stainless steel can be left as it is painted with an emulsion paint, be clad with coarse-grained plaster made of colored cement or with a bitumen layer protected by a grained, colored mineral to be disguised. The described variants of the external appearance of the seal

do not represent an exhaustive list.

The material used according to the invention is known per se Way built and manufactured. The manufacture done in the factory occurs, there is at least one layer of a glass reinforcement with a weighted or not weighted in the sheathing bituminous binder based on bitumen or a mixture of bitumen and elastomers, the binder being heated at, for example, 200 ° C, is poured onto the reinforcement so that the latter is completely immersed in the binder. The thickness of the binder is therefore always greater than that of the reinforcement. In this way a flexible layer is obtained reinforced bitumen. A foil made of stainless steel is glued to one side of the still warm bitumen, either before or afterwards can be provided with a surface treatment described above. The other side of the reinforced bitumen is with an anti-stick coating (sandstone, silica, talc or paper) that prevents the material from rolling up after cooling permitted; without the anti-stick coating, the material would stick to one another. The material can be rolled up this way be stored. For the production of a seal, whereby a roll is gradually unrolled and thereby on the wall and the floor, the butt joint of which is to be protected and which are generally made of concrete, is welded on. The top layer Asphalt or similar material can be poured onto the ground after the waterproofing has been applied and covered then the horizontal part of the waterproofing.

In the case of the material described, the glass reinforcement ensures the Resistance to dynamic loads, the bituminous binder, the resistance to cracking and the rustproof Steel foil's resistance to static loads.

For the purpose of illustration only and in no way restrictively, an exemplary embodiment of the material is given below :

- The reinforcement is made of a glass fleece of 50 g / m ² coated with a glass fabric of 280 g / m ² ,

- The binder consists of a bitumen-elastomer mixture, for example as in the French one Patent 73.17159,

- The stainless steel foil has a thickness of 50 μπ>.

In the context of equivalent techniques, changes to details of the method are conceivable that do not go beyond the scope of the invention blast can be realized by a specialist.
