Definitions

  • the invention relates to a seal for a joint between two concrete parts.
  • vertical and horizontal joints are possible.
  • the vertical joints usually run between two wall parts made of concrete.
  • Horizontal joints can be bounded by concrete walls on the one hand and the sole of a structure formed as a concrete slab on the other hand.
  • the walls to be formed in concrete are not cast in one piece on site (in-situ concrete). Rather, individual wall parts are prefabricated, delivered as a whole to the site and connected there.
  • these element walls consist of two limiting individual walls, between which there is a steel reinforcement for stabilization. Only the space left next to the reinforcement is filled with in-situ concrete on the construction site. In this way, the construction phase can make extremely time-saving and inexpensive. Due to the industrial prefabrication, the wall surfaces have a dense concrete structure with water-impermeable properties.
  • the weak points of the construction are the joints necessarily formed, which in particular remain vertically between the individual element walls but also horizontally between the element walls and the building sole. Through the joints penetrating water can spread in the course of time in the cavities, which are despite filling with in-situ concrete still between the individual walls. In this way, it may even come after a while to a complete moisture penetration of the entire concrete wall.
  • an adhesive is known, the crosslinked by absorption of moisture by preparation of an organopolysiloxane compound with elimination of alcohol to form an elastomer.
  • organopolysiloxane compounds are also referred to as silicone resins or silicones. These are compounds with SI-O chains as a backbone.
  • this adhesive has the disadvantage, although as I said by absorption of moisture curing, not readily adhere to damp substrates.
  • CH 674749 describes a sealing tape for construction joints made of a flexible film strip, the edge regions of which are connectable with an adhesive and sealing compound with joint surfaces.
  • the mass is applied in the form of two parallel adhesive strips on the foil band which are covered with an easily detachable protective tape.
  • adhesive and sealant known here "hotmelt butyl”, “hotmelt PU” or dispersion adhesive is proposed. These adhesives also have the disadvantage of not sticking to damp substrates.
  • bituminous seals After a primer, which is applied to dry or slightly damp, mineral-bound substrates (eg bitumen rubber precoat), a bitumen waterproofing membrane can be applied. It is also known to make this web self-adhesive (cf, for example, the product Bitucoat KSK).
  • a disadvantage of this known solution is that a primer is required in each case with the primer. The primer can only be applied on a firm, load-bearing, clean, oil and grease-free and defect-free surface and not over gaping cracks, burrs as well as sharp edges. This circumstance represents a significant limitation in practice for bitumen-based joint seals, since their use is not independent of weather conditions.
  • bituminous layer is to be chosen very carefully: on the one hand, an excessively thin layer thickness would mean that the application of bitumen would not be able to withstand the upcoming water pressure and that the layer is not sufficiently able to bridge cracks. On the other hand, the bituminous layer must not be too thick, since otherwise the through-drying process (and thus also the overall construction process) could be slowed down. In addition, this would possibly occur the so-called peat effect with severe cracking.
  • the invention has the object of providing a seal for a joint between two concrete slabs in such a way that the hedge against penetrating water is permanent and at the same time a weather-independent installation is possible. This object is achieved by a seal according to claim 1.
  • the film consists essentially of tear-resistant rubber and / or elastomer. Through these substances can be achieved that the sealing film clings to bumps on the surface. In particular, these materials can also be used when the joint to be sealed is at an angle, such as between the bottom plate of the building and an erected thereon element wall. In another advantageous embodiment, the side of the film facing the adhesive and sealing compound can be used. This is a particularly durable and firm connection between the film and the adhesive and sealant can be achieved.
  • the life of the joint is increased if the film is advantageously weathering, UV light, and / or frost resistant.
  • the film may advantageously have a thickness of at least 0.5 mm.
  • the joint it is advantageous for the joint to choose a film width of at least 20 cm, so that there is sufficient space for the adhesive strips adjacent to the two longitudinal sides of the joints.
  • the adhesive and sealant can be solvent-free, isocyanate-free and plasticizer-free and can also be processed in wet and / or wet surfaces.
  • These properties of adhesives and sealants are very rare, in particular the isocyanate is not given in the usual polyurethane compositions.
  • considerable advantages are ensured with such an embodiment of the adhesive.
  • Such a mass is pasty and hardens to an elastic product. In particular, but can thus effectively avoid that the adhesive and sealing compound is porous and cracked over time. That the adhesive and sealant is to be processed even on wet surfaces, ensures a safe and delay-free planning of the construction. Last but not least, this can save considerable costs.
  • the adhesive and sealant may be weatherproof in the cured state and have a high strength. These properties also increase the durability and reliability of the joint seal.
  • the adhesive and sealant is based on silane-modified polymers. Such a basis is also called MS hybrid basis.
  • This adhesive and sealant has the said, for the invention, particularly advantageous properties. It is particularly weather-independent and can be applied to the surfaces without primer. Silane-modified polymers adhere to both rubber and concrete, providing a UV-resistant and extremely strong bond. It is particularly advantageous that these adhesives and sealants cure even on moist ground and even under water. Moisture even accelerates the process of curing.
  • the film is not attached to the two concrete walls each with a separate adhesive sheet, but by means of a single adhesive sheet, which sweeps over substantially the entire width of the film. This ensures a particularly good grip. At the same time, disruptive air bubbles or air spaces between the individual adhesive webs can be avoided.
  • the elastic waterproof films used for the invention are usually manufactured and supplied in webs. At the end of such a web, this results in a subdivision of the film transversely to its longitudinal direction.
  • an overlap of 50 to 100 mm can then be provided in the joint area, wherein the adhesive web can extend between the overlapping film sections.
  • the seal may be provided on the acted upon with pressurized water construction site.
  • the water pressure in this case contributes to the stability of the joint seal by pressing the film with additional force on the concrete slabs and on the joint.
  • Fig. 1 shows the cross section through a horizontal joint between a concrete floor and an upstanding concrete wall.
  • Fig. 2 shows the cross section through a seal for a vertical joint between two concrete walls.
  • a wall 3 is arranged, which is formed in the embodiment as a triple wall and consists of two finished plates 4 , which are arranged at a distance from each other and are connected to each other via a lattice girder 6.
  • the space 7 between the finished panels 4 is filled with in-situ concrete.
  • the concrete base 2 extends beyond the wall 3 , so that a paragraph 8 results.
  • a joint 16 which is provided with a seal according to the invention.
  • This seal consists essentially of a waterproof film 9 , the film is elastic and thus can be easily fitted in the right-angled corner.
  • the contact pressure of the film is additionally increased in this arrangement, which additionally improves the strength of the connection and the durability of the sealing connection.
  • Fig. 2 the cross section is represented by a seal for a vertically extending joint 16 .
  • the joint was filled with a filler 13 and thus created a substantially flat surface.
  • the 30 cm wide sealing foil 9 is attached with an adhesive sheet 15 to the two concrete walls.
  • the adhesive sheet essentially covers the entire width of the film. This way, air bubbles inside the glue web can be avoided and a particularly permanent hold is guaranteed.
  • the thickness of the film is 1 mm chosen so that a high resistance to mechanical stress is given.
