Definitions

  • the invention relates to precast concrete parts, in particular concrete floor panels for parking garages, with at least one projecting in the upper region edge, which covers a embedded in a sealing compound reinforcement.
  • Such precast concrete parts are known per se. They have a projecting edge in the upper region, below which a cavity is formed, in which, for example, a connection reinforcement can be located.
  • the projecting edge region may extend over a more or less long portion of the plate.
  • a correspondingly larger cavity is formed in which the reinforcing elements for fixing the adjacent plates to one another and / or for connecting the plates to one another can be located.
  • These reinforcing elements are generally made of steel, so that they are sensitive to corrosion. The corrosion plays a role, in particular, when the concrete cover is relatively low and is insufficient to prevent road salt (chlorides) from the metallic reinforcements.
  • the cantilevered upper portion of the rim has a relatively small thickness relative to the other plate thickness, because beneath the cantilevered portion an adequate cavity for receiving the reinforcing and connecting elements must be formed. The thickness of the projecting portion is therefore insufficient for effective protection of the reinforcing elements.
  • the concrete parts are concrete floor slabs for parking garages, these have a cantilevered upper area which, for example, covers an abutment reinforcement, as already explained.
  • the invention is therefore the object of concrete precast parts in such a way that even in areas where the concrete layer has a relatively low thickness, corrosion-prone parts are secured below this thinner layer of concrete from the ingress of salts.
  • prefabricated parts according to the invention are characterized in that a projecting the upper region from below under saptternde, waterproof cover is provided on the edge of the precast concrete parts.
  • This cover which may for example consist of a waterproof plastic, is cast together with the corresponding precast concrete parts. It can therefore have on the concrete facing surface anchor parts that secure the connection with the concrete. Even at the edges, the covers can be deformed so that they can be poured into the concrete.
  • Fig. 1 is the joint area between two concrete floor panels 10,12 shown, for example, form the bottom of a parking garage.
  • the two concrete floor slabs 10, 12 lie on a double-T support 14 with the insertion of elastic support elements 16, 18.
  • On the surface of the upper flange 20 of the double-T-beam 14 are two welded, vertically projecting pins 22,24.
  • the pins 22, 24 have flange-like outwardly projecting heads 26, 28.
  • the pins 22,24 lie in a recess 30,32 of the respective bottom plate edge, so that the pins 22,24 are overlapped or covered by upper projecting portions 34,36.
  • the pins 22,24 serve to anchor the connecting reinforcements 38,40, which emerge from the mutual plate edges and engage around the pins U-shaped.
  • coupling members made of reinforcing steel can be provided, which are wrapped around the two pins together and thus form a stadium-shaped loop.
  • the two recesses 30,32 and lying between the two floor panels gap 42 are filled with a potting compound, which embeds the two pins 22,24 and the various reinforcing bars.
  • the two recesses within the plate edges, indicated at 30 and 32, are lined with a watertight cover 44, 46 which is poured into the concrete mass.
  • a watertight cover 44, 46 which is poured into the concrete mass.
  • For anchoring in the concrete are on the vertical outer surfaces of this cover anchor members 48, 50 and bent at the lower edges lower edges 52,54, which also allow anchoring in concrete.
  • Also in the region of the upper edge are on the outside of the anchor parts 56,58 on the outer surfaces of the cover 44,46 for anchoring in the concrete.
  • Fig. 2 shows the situation in a plan view or a horizontal section. The cut of the Fig. 1 is in Fig. 2 entered. In Fig. 2 are the same reference numerals as in Fig. 1 has been used, so that a re-description should be unnecessary.
  • the U-shaped, emerging from the two bottom plates 10,12 reinforcement members 38,40 are wrapped around the two pins 22,24 and hold in this way the bottom plates 10,12 in their respective position.
  • a closed, stadium-shaped reinforcement 60 can be wrapped around the two pins 22,24.
  • the cantilevered upper portion of the two edges of the plates extends in the present embodiment only over a relatively short area, but provides sufficient space for receiving the illustrated armor.
