Definitions

  • the invention relates to the sealing of floor joints, according to the preamble of claim 1.
  • Floors are created in such a way that changes in length of the building are provided by so-called construction joints. Thanks to this technique, there are no excessive tensions in the structure of the floors and the superstructure, which would otherwise result in mechanical destruction of the building material by overstressing it.
  • the planned separation of the floors into elements a few meters wide by approximately 9 to 28 mm wide, by floor joints makes it possible to avoid uncontrolled cracks and gaps in the building object.
  • the floor joints planned in advance are sealed against the ingress of weather by filling the construction joint with plastic-elastic materials. Due to their function, the fillers of the floor joint are often exposed to weathering. Over time, these influences of the weather cause the joint seal to decompose, degrade and disintegrate.
  • expansion joint profile is proposed in publication DE-A-1 658 994, for example.
  • This expansion joint profile consists of angle rails (1) which cover the joint walls of the floor joint and a cover flat rail (3) with rubber glued on the underside -Band and with clamping devices (7) with four-channel connectors (5), countersunk screws (4) and securing devices (6) distributed along the cover flat rail, connected to it, which can be lowered into the building joint and spread between the angle rails (1), as well as various fastening anchors (2) and nails for fastening the fastening anchors (2).
  • the object of the present invention is to eliminate the disadvantages mentioned.
  • the sealing of floor joints consists of a cover profile made of a protective cover profile made of corrosion-resistant metal, which can be extended as required by attachments, and distributed along the cover profile with connected clamping devices which protrude into the floor joint and are to be clamped between the joint walls.
  • the cover profile is flush with the floor level and does not protrude, the cover profile is embedded in the floor.
  • This arrangement reduces the rolling resistance of the floor joint and the edge pressure (normal stress at the edge of a load body) of the joint edges in the sense of DIN 1054 by improving the load distribution.
  • the preferred cross-sectional shape of the cover profile is an isosceles trapezoid, the longer of the parallel ones Sides of the cover profile lies in the floor level. The edges of the floor recess are therefore obtuse, and thus protected against overstressing the normal force of the load.
  • the floor joint serves to center the milling process.
  • the countersunk bores of the clamping screw are distributed along the axis of symmetry of the cover profile and serve to accommodate the expandable clamping devices which can be clamped between the joint walls of the building joint.
  • the clamping device is centered by the clamping screw and guided through the floor joint so that they are slidably connected to the cover profile before tightening.
  • the ends of the cover profiles are formed in the manner of a font. These spikes allow a certain shortening or lengthening of the cover profiles as a result of temperature changes in that they can move towards each other in a scale-like manner.
  • the precision of the sparing keeps the distance of the profiles close to each other, so that the penetration of precipitation is excluded in this way. Since the edges of the cover profiles are broken, a contact surface is created at the edge of the cover profile. This contact surface is pressed against the edge areas of the recess by tightening the clamping screws. Depending on the requirements of the tightness, the material of the seal is determined, and in the recess. EPDM and butyl cement in strip form may be mentioned as an example of the sealing material.
  • EPDM and butyl cement in strip form may be mentioned as an example of the sealing material.
  • the laying of an additional seal is proposed. It has the shape of a tarpaulin and is laid as a sealing membrane under the floor body, which is separated from one another by the floor joint, parallel to the plane.
  • cover profiles are preferred for cover profiles.
  • Corresponding aluminum alloys are suitable, which are inexpensive to process by extrusion. Since bare metal surfaces may be undesirable for aesthetic reasons, the cover profiles can be matt or colored anodized after their manufacture, or can be provided with two components of epoxy resins that are suitable for aftertreatment.
  • the advantages achieved by the invention can be seen in the excellent load distribution and the aging resistance of the cover profile and thus in the improvement of the load-bearing capacity of the floor joints, in the levels and quality of the tightness and in the rationalization effects.
  • the cover can be laid using the simplest of means, such as a pocket knife and screwdriver, by cutting a cutout from the plastic foam filling of the floor joint. If the floor joint seal is required, the seal is relocated after creating the recess. If sealing of the construction joint is required, the sealing membrane must be introduced before the floor body is poured.
  • the application The invention is suitable for new buildings and, with the exception of sealing, also for renovation measures.
  • the invention is an effective and inexpensive prophylaxis for structural damage and thus a means for economical building.
  • Fig. 2 shows a cross section of the open floor joint with the floor body and the sealing membrane.
  • FIG. 1 The joint seal shown in FIG. 1 bridges the gap formed by the floor bodies 11 and 12 through the cover profile 2.
  • a gap is called the floor joint and is filled with plastic foam 13 except for the clamping device 3, consisting of the expansion body 4 and the wedge 5 and the clamping screw 6 placed therein.
  • Fig. 1 shows the non-positive system of anchoring.
  • the clamping screw 6 generates a bending stress in the bridge-like cover profile 2, which causes the pressing and sealing of the Contact surfaces of the edges 2.2 and 2.3 on the components 11 and 12 and the seals 2.4, 2.5 results.
  • 2 shows the two structures 11, 12 with the open floor joint and the plastic foam 13 located therein and the sealing membranes 7 overlapped in the area of the floor joint.
  • the sealing membranes are plan-like, lie plane-parallel to the structures 11, 12 on the building ground and enclose the structures for the purpose of hermetic sealing.

Abstract

L'étanchement de joints de revêtement de sol entre deux unités structurales (11, 12) comporte un profilé de recouvrement (2) de section de préférence trapézoïdale isocèle et, selon les spécifications d'étanchéité, les joints (2.4, 2.5), ainsi qu'une membrane d'étanchéité posée sous les unités structurales (11, 12) de manière parallélépipédique par rapport au sol, ainsi que des dispositifs de serrage (3) qui font saillie dans le joint de construction (11, 12, 13) et peuvent faire expansion entre les parois du joint à l'aide de la vis de serrage (6), de manière à appuyer contre les parois du joint de construction (11, 12) et à être ancrés par liaison de force due à la friction du dispositif de serrage (3) sur les parois du joint de construction (11, 12). Bien que les éléments de recouvrement soient fabriqués en longueur uniforme, leurs extrémités du type à glissement permettent la réalisation de joints étanches à l'eau et par conséquent de n'importe quelle longueur d'étanchement des joints de construction.
