Definitions

  • the invention relates to a bituminous covering for bridges with superstructures made of concrete, in particular prestressed and reinforced concrete, consisting of the actual surface layer (layer exposed to traffic) made of poured asphalt or asphalt concrete with a thickness of 35 mm, a protective layer made of poured asphalt from under the surface layer also y 35 mm thick and a sealing layer of about 4.5 mm thick, the z. B. can consist of a welding track with a carrier insert, the bitumen content in the welding track can be between 60 and 100 wt .-%.
  • the so-called sealing layer is of particular importance for such bridge coverings, because it mediates the transition between the thermally and mechanically flexible top layer and the rigid concrete superstructure of the bridges.
  • the concrete of the bridge superstructure is provided with a seal, which usually has an additional separating layer. This has the task of absorbing or preventing the swelling and bulging when the volume increases, due to moisture evaporating from the concrete, by expanding air and other gases when the temperature rises.
  • a glass fleece which is applied directly to the concrete surface, generally serves as the separating layer. This separation layer is then followed by a layer of asphalt mastic of the thickness mentioned above. For a given bitumen content, additions of fillers are common, so that one from sufficient strength against the heat of the mastic asphalt as a protective layer and the mastic asphalt or asphalt concrete as a final top layer is guaranteed.
  • metal corrugated strips for example made of aluminum or copper or stainless steel, in addition to, or instead of, the asphalt mastic.
  • a primer for example on a bituminous basis, is applied to the cleaned and dry concrete surface with about 0.25 to 0.40 kg / m 2 bitumen solution.
  • a separating layer made of perforated glass fleece bitumen membrane, the purpose of which is, among other things, to relieve the pressure of vapors and gases.
  • the metal corrugated tapes are then glued to this, in particular in the pouring and rolling process using an adhesive, for example made of bitumen filled with slate flour or fibrous materials.
  • the subsequent protective layer consists of pure mastic asphalt.
  • prefabricated bituminous welding sheets are used instead of the casting and rolling process or adhesive process, the surfaces of which are metal and plastic laminated.
  • the perforated glass fleece bitumen membrane is dispensed with and the sealing membrane is flamed onto the bitumen welding membrane on the concrete surface provided with plastic and / or bituminized primer.
  • German utility model 83 36 945.7 which is to be regarded as a technological background.
  • the metal foil itself is not subject to any mechanical stress due to excess pressure, so that the risk of reducing the. Layer composite, cracks, bubbles, etc. is fixed. The sealing effect of the sealing and protective layer forming the seal is thus also fully retained.
  • the invention thus relates to a bituminous covering for superstructures made of concrete, in particular prestressed and reinforced concrete, consisting of the actual top layer of cast asphalt or asphalt concrete, the bituminous protective layer and a sealing layer forming the transition to the concrete with metal foil, characterized in that the metal foil is a Perforation or perforation, which is between 1 and 25%, in particular between 5 and 10% of the total surface of the metal foil, the individual, predominantly statistically distributed perforations having a diameter of 0.01 to 1 mm, in particular, especially 0.1 up to 0.5 mm.
  • metal foil is understood to mean both smooth and structured foils, plates, strips, etc., as will be shown later.
  • Aluminum and stainless steel are particularly suitable as the metal or material for the film, although copper and similar non-ferrous and light metals are also suitable.
  • the term structured encompasses those configurations which have elevations protruding from the plane. Examples of this are corrugations, corrugations, nubs of any geometric habit (squares, rectangles, cones, hemispheres, paramids, etc.).
  • the thickness of the metal foil in the place of which plates or strips can also be used, is between 0.05 and 1 mm, in particular between 0.10 and 0.3 mm (wall thickness). It has been shown that instead of metals, thermally stable up to the temperature of the hot mastic asphalt (for top and protective layer) stable high polymers, such as hard PVC, post-chlorinated PVC, polyethylene, polytherephthalic acid esters, polyacrylates, etc., as well as corresponding copolymers with two and more types of monomers are quite suitable. Occasionally, however, certain deviations from the wall thickness of the ranges specified above are necessary in order to ensure sufficient compressive strength for a given coefficient of thermal expansion. In general, the wall thicknesses of polymers and copolymers are up to 100% larger than that of aluminum or stainless steel.
  • the size of the free that is to say volatile constituents of the concrete, which is formed after the perforation or perforation in the film forming the sealing layer, be it from metal or from a polymer or copolymer material, is generally about 1 to 25% of the total area the film that faces the protective layer. Below approximately 1%, the pressure compensation behavior of the film is considerably restricted and can only be used to a limited extent, while above approximately 25% the mechanical stability of the film is endangered. Especially when using metals such as aluminum or stainless steel, the upper areas of the free area quite acceptable, while the lower limit values are more important for plastics. However, it is generally pointed out that this criterion results from area-wide tests, so that there is no absolute restriction on material and perforation area. In general, open areas between about 5 and 10% of the total surface area of the film are preferred.
  • each hole i.e. their diameter
  • the size of each hole ranges between 0.01 and 1 mm and is directed among other things also according to the mechanical strength of the film material.
  • the number of perforations per unit area is generally greater than in comparison with perforations of large diameter or opening cross section.
  • the arrangement of the perforation or perforation is generally and preferably statistical, i.e. there is an even distribution over the entire surface facing the protective layer.
  • the geometrical shape of the perforations can be of any type, although a circular habit is preferred for reasons of simple manufacture (drilling or punching). However, other shapes such as squares, rectangles, polygons, slots, etc. are also suitable.
  • the simplest form of the perforated film can occasionally also be formed by a fabric, the mesh size of which determines the free area which allows volatile components to pass out of the concrete.
  • the perforations or perforations in the film have a further, not inconsiderable advantage, which consists in the fact that in Area of the perforations, hot bitumen from the overlying protective layer can penetrate into the film and / or from the welding path into the overlying protective layer and, after cooling, leads to a highly stable anchoring between the protective layer on the one hand and concrete on the other hand, the film itself being fixed in its position, so that there is continuous stabilization of the entire covering.
  • the perforations in the metal or polymer film are open, which means that when the hot mastic asphalt is applied, the volatile substances contained in the concrete can escape without hindrance.
  • a further advantage particularly with regard to the stability and the cohesion of the covering, are the fragments remaining when punching out or pressing out the perforations from the film material and still connected to the film surface, the ends of which, like a grater, after application of the mastic asphalt Protective layer protrude into the mastic asphalt (protective layer).
  • Such upward fragments at the edge of the perforations not only lead to a directed passage of the volatile components from the concrete through the perforations, they also form an additional anchoring of the foil, which in this case is made in particular of metal, in the protective layer.
  • the hitherto customary construction of a bituminous covering for superstructures made of concrete initially consists of the cover layer (a) made of poured asphalt or asphalt concrete, followed by the protective layer (b), preferably also made of guasphalt, which can also also serve as a seal, the sealing layer, preferably made of asphalt mastic (c), a separating layer (d) made of raw glass fleece and then the concrete (e) of the bridge board.
  • This version does not use a foil-containing (metal or plastic) sealing layer.
  • the top and protective layers (a, b) correspond to the known structure.
  • a bitumen welding sheet (f) with laminated aluminum foil the welding sheet (f) possibly being glued over the entire surface of the concrete of the bridge panel (e) using a primer.
  • the aluminum foil provides a perfect seal.
  • the aluminum foil is structured, So for example as a corrugated or No pp en film is formed. A passage of pressure-increasing gases and vapors through the welding path remains blocked.
  • FIG. 2a shows a first embodiment of the covering structure according to the invention.
  • Cover and protective layer (a, b) are again largely identical to the corresponding layers according to FIGS. 1a and 1b.
  • the sealing layer or welding track (g) is provided with a film covering which has a statistically distributed perforation (j).
  • this is an unstructured film, plate or tape, e.g. made of aluminum, stainless steel or plastic, the statistical hole distribution of e.g. Embossing, punching or drilling was obtained.
  • the sealing layer or welding track (g) lies on the concrete (e) with the application of a primer (h) made of bituminous adhesive or a plastic adhesive over the entire surface.
  • FIG. 2b shows the structure according to the invention of a covering with structured film (j) and additional separating layer (k) made of raw glass fleece.
  • the film (j) in the special case made of aluminum or stainless steel, is constructed in the manner of a corrugation or knot, in which the perforations are provided exclusively in the elevations or knot surfaces.
  • FIGS. 1a, 1b, 2a and 2b only show the covering structure schematically, that is to say that both material from the protective layer (b) and from the raw glass fleece (k) intervene in the existing empty spaces above or below layers .
  • FIG. 3a The simplest form of the perforated or perforated film is shown in FIG. 3a. This is a flat, non-structured surface (j) with statistically distributed perforations, mainly of the same diameter.
  • the perforation can also have other geometric shapes and e.g. be conical (1).
  • FIG. 3d A structured, perforated film according to the invention is shown in FIG. 3d.
  • This is a corrugated or knobbed sheet, the uppermost surface areas of which have the perforation (1) according to the invention.
  • the perforation is not limited to the flat or horizontal areas (3) of the knobs, it can also be carried out - alone or in addition - in the inclined surfaces as long as they are in the space above the film (j), i.e. in the direction of the protective layer (b) - see FIG. 2b - opens out. It is understood that dimpled sheets of this type are not bound to the geometry of FIG. 3d.
  • the upstanding knobs (3) can be larger or smaller than the remaining floor areas. Knobs of different sizes can also alternate with one another distributed over the film surface.
  • the anchoring effect of the perforations is particularly apparent from FIGS. 4 and 5.
  • the sealing layer which is designed, for example, as a welding track (g) with metal foil (j) and raw glass fleece (k), which is primed (h) with the concrete (e) liquid bitumen (4) from the protective layer (b) enters the perforations (1) of the film (j) and fills the perforations (4 ').
  • the bitumen can also penetrate into the fleece (k) or another suitable carrier insert (4 "), so that a continuous anchoring between the protective layer (b) and concrete (e) after the bitumen (4, 4 ', 4 ") given is. Since the cooling process of the bitumen takes place with a time delay, the evaporating volatile constituents in the concrete are given sufficient opportunity to escape before the bitumen solidifies.
  • This anchoring process is intensified if, as shown schematically in FIG. 5, the fragments discussed above in connection with FIG. 3c are retained at the edge of the perforation.
  • These material fragments (2) form an upward and / or downward exit for the volatile constituents in the concrete and ensure additional, particularly firm anchoring of the film and thus of the entire sealing layer.
  • FIG. 6 shows a particularly advantageous embodiment of the corrugated or nubbed sheets according to the invention as part of the sealing layer, in particular if this is designed as a welding sheet.
  • any geometric shapes can be formed, which are based on parallel to FIG. 6b of parallel corrugations or, according to FIG. 6a, are made up of knobs arranged offset to one another.
  • the perforations (1) are not bound to the uppermost (flat or horizontal) surfaces. They can also be provided in the side surfaces (3, 3a, 3b) and e.g. be designed as slots.
