Definitions

  • the invention relates to a component for thermal insulation between a building and a cantilevered outer part consisting of an insulating body to be laid between them with metallic reinforcing bars which extend transversely to the insulating body, protrude on both sides and are protected against corrosion at least within the insulating body and in the adjacent transition area , wherein the corrosion protection is formed at least in part of the reinforcing bars by a coating and also an abrasion protection is provided for this coating.
  • a component with the features described above is known from GM 90 14 573.
  • the reinforcement bars are included provided with a plastic coating in the insulating body and in the adjacent transition area and frame-shaped brackets are attached to the insulating body to protect it from abrasion. This ensures that there is no local abrasion of the coating when handling the construction site, especially when laying the connection reinforcement.
  • the present invention has for its object to develop a new solution for abrasion protection, which is characterized by easier assembly and lower manufacturing costs.
  • the new abrasion protection should also improve the corrosion resistance of the reinforcing bars in the endangered transition area.
  • the abrasion protection consists of a tube which surrounds the reinforcement bar at least in the transition area, that this tube is spaced by inwardly projecting projections and arranged to form a ring-like gap on the reinforcement bar and that the projecting over the insulating body Ends of the tube have a plurality of openings in the tube wall, which allow the entry of concrete or milk into the gap.
  • the tube according to the invention has the advantage that it is much easier and cheaper to manufacture and assemble than the previously known bracket.
  • the reinforcing bar through its openings and the spaced arrangement on the reinforcing bar, it ensures that the annular gap between the pipe and the reinforcing bar is filled with concrete or concrete milk, which results in the surface the reinforcement bar sets a basic environment that is particularly favorable for its corrosion protection.
  • the described filling of the annular gap is further facilitated by the fact that openings are also provided in the upper circumferential area of the pipe, from which the air displaced by the concrete can escape.
  • the inwardly projecting projections of the tube are formed by longitudinal ribs.
  • the tube can be manufactured inexpensively in the extruder.
  • the height of the projections is expediently chosen to be greater than 1.5 mm, in particular from approximately 2 mm to approximately 10 mm. This ensures reliable filling of the pipe with concrete or concrete milk.
  • the positioning of the openings in the area of these longitudinal ribs also serves the same purpose, because the flow resistance in the annular gap is thereby reduced. At the same time, this increases the contact area between the reinforcement bar and concrete.
  • the size and number of openings are preferably chosen so that they take up a total of about 20% to about 50% of the tube wall area, in particular about 30% to 40%.
  • abrasion protection consists of a helix surrounding the reinforcement bar in the form of a helical thread, the pitch of which is dimensioned such that adjacent screw threads are axially spaced apart.
  • FIGS. 1 and 2 a series of successive, rectangular insulating bodies 1 made of polystyrene is laid between the components to be insulated. These insulating bodies are traversed in the upper half by a plurality of tension rods 2, in the lower half by corresponding compression rods 3 and, if appropriate, by transverse force rods (not shown further). These reinforcing bars have a corrosion-protective coating, at least within the insulating body and in the adjacent transition area, which is to be protected against abrasion, for example by steel mats or the like that drag along.
  • FIGS. 3 and 4 For this purpose, they are not arranged directly in the insulating body 1, but surrounded by a plastic tube 4 or 5, which crosses the insulating body along a recess 7 and is shown in more detail in FIGS. 3 and 4.
  • This plastic tube sits coaxially over inner longitudinal ribs 4a and 5a, forming an annular gap 6 on its reinforcement element, in FIGS. 3 and 4 on the tension rod 2.
  • the tube wall is provided with numerous openings 4b and 5b, at least at the projecting ends, which are produced by drilling or milling and in particular are also arranged in the region of the longitudinal ribs 4a and 5a. This ensures reliable filling of the annular gap 6 when concreting the components adjacent on both sides of the insulating body 1.
  • longitudinal ribs 4c and 5c are also arranged on the outside of the tube. They primarily serve as additional abrasion protection. In addition, they can also support the fastening of the tube in the insulating body if, as shown in FIG. 3, they protrude a little into the insulating body. In this case, it is only necessary to provide a cylindrical through hole in the insulating body 1; When the tube is subsequently pushed in, the longitudinal ribs 4c then dig into the elastically and plastically yielding insulating material of the insulating body 1, as a result of which the tube 4 is retained by itself.
  • the tubes can also be glued to the insulating body or attached in some other way.
  • Figure 4 differs from Figure 3 essentially in that the recess 7 in the insulating body 1 is not circular cylindrical but has an upper bulge 7a. This bulge is connected to the annular gap 6 via bores 5b and facilitates the escape of air when the concrete milk penetrates into the annular gap.
  • Figure 5 shows a tube 4 ', in which the outer ribs 4'c have been partially omitted within the insulating body; they are shown in dashed lines and only begin outside the insulating body 1 up to the pipe end to run. As a result, the tube 4 'is held in the insulating body 1 in a form-fitting manner in the axial direction.
  • FIG. 6 shows an alternative in which, instead of the tubes 4 and 5, spirals 14 and 15 are arranged above the reinforcing bars 2 and 3, respectively.
  • these coils allow the reinforcing bars to be reliably encased in concrete, similar to the pipes described above.
