Definitions

  • the invention relates to a coupling element for composite components with rigid cover layers and a core layer made of closed-cell rigid foam, which is produced by foaming a reaction mixture introduced between the cover layers with simultaneous venting of the cavity, a coupling half of each in the end faces or in the edge region of the side faces of the composite component
  • Two-part hook couplings is arranged, each of which comprises a locking bolt or pivotable locking hook arranged in a housing.
  • Coupling elements of the type described above for composite components are known. These composite components are assembled on site by means of the two-part hook couplings, for example to form cold rooms or cold stores, in that the composite components forming the floor, the side walls and the ceiling are connected to one another with the aid of the two-part hook couplings.
  • the housing of the coupling halves which either contains a locking bolt or a pivotable locking hook, is for this purpose arranged at predetermined points in the end faces or in the edge areas of the side faces of the composite components.
  • the known composite components are manufactured in a stable shape, in which the lower cover layer, then the housing of the hook couplings and finally the upper cover layer are inserted, the housings being plugged onto the side or cross bars of the mold that form the later end faces of the composite component form.
  • the preferably liquid reaction mixture is introduced into the cavity, the volume of the reaction mixture being between 35 and 45% of the total volume of the core layer to be produced.
  • the foam which expands under an overpressure of up to 2 bar, fills the entire cavity by displacing the air in the cavity of the mold and, during its subsequent curing, not only connects the rigid cover layers to one another, but also holds the molded-in coupling halves.
  • Vent openings must be provided so that the air displaced during the foaming process can escape from the cavity of the mold. These are provided either in the cover layers or in the side and cross bars of the mold. The foam emerging from these ventilation openings must be removed after the composite component has been completed.
  • the invention has for its object to provide a coupling element for composite components of the type described above, in the manufacture of which there is no need to provide special ventilation openings.
  • the solution to this problem by the invention is characterized in that the housing of the hook couplings are provided with a plurality of ventilation openings.
  • the formation of the ventilation openings required for the manufacturing process on the housings of the hook couplings eliminates the need to provide special ventilation openings or to use them as prefabricated moldings in the mold for producing the composite components. Since the housing of the hook couplings is evenly distributed over the circumference of the end faces, the proposal according to the invention results in a uniform and good ventilation of the cavity without special measures having to be taken for this.
  • the ventilation openings are designed as channels with a small cross section and a length greater than the cross section, so that although air can escape almost unhindered, the escape of foam is prevented. This eliminates the need to rework the composite component by removing excess foam.
  • the ventilation openings are formed between the interior of the housing and an outer surface of the housing facing the interior of the composite component. The ventilation is thus carried out via the interior of the clutch housing.
  • the ventilation openings are formed within stopper-like projections which are formed on the rear of the housing.
  • the ventilation openings are formed within chambers formed on the side of the housing.
  • the cavity is not vented through the interior of the clutch housing, but through the chambers formed on the side of the clutch housing, so that even foam passing through the ventilation openings does not get into the interior of the clutch housing.
  • the ventilation openings can be formed with a circular cross section or with a cross section in the form of a circular arc.
  • This cross-sectional design enables a particularly simple production of the ventilation openings as channels with a small cross-section and a great length.
  • the ventilation openings are covered by a textile fabric with openings of small cross-section.
  • this textile fabric can be formed by a mat made of needle felt.
  • the textile fabric is preferably arranged in a frame-like recess in the housing.
  • the ventilation openings covered by the fabric can be formed by webs which are spaced apart and parallel to one another.
  • FIG. 1 shows the construction of a cooling cell from composite components 1, which according to FIG. 3 consist of two rigid cover layers 2 and 3 and a core layer 4 of closed-cell rigid foam using an exemplary embodiment.
  • Two-part hook couplings are arranged in the end faces or in the edge region of the side faces of the composite components 1, each of which comprises a locking bolt arranged in a housing 5 or a locking hook pivotable in a housing, as can be seen in the upper left part of FIG. 1.
  • the composite components 1 are produced in a mold as shown in FIGS. 2 and 3.
  • This mold comprises a mold base plate 6, on which a rigid cover layer 2 according to FIG. 3 is placed.
  • the end faces of the composite component 1 are formed by molded side rails 7, which can best be seen in the top view of FIG. 2.
  • the coupling housings 5, which are to be molded into the end faces of the composite component 1 in the exemplary embodiment shown in FIG. 2, are attached to these molded side rails 7.
  • the second cover layer 3 is placed in the mold and the mold is closed by applying the mold cover plate 8.
  • a reaction mixture is now introduced into the cavity of the mold via the filling tube 9 shown in FIG. 2 and forms the core layer by foaming. In this case, the air between the cover layers 2 and 3 in the mold must escape. This is done - as the arrows in FIG. 2 indicate - through the clutch housing 5.
  • plug-like projections 10 are formed on the rear of the housing 5, in each of which a plurality of ventilation openings 11 are provided.
  • These vents 11 are designed as channels with a small cross section and a large length compared to their cross section, so that although the air can escape almost unhindered, leakage of the foam is prevented.
  • the channel-shaped ventilation openings 11 have a circular cross section, which can be formed in a simple manner in the manufacture of the coupling housing 5 from plastic.
  • the air emerging from the interior of the mold through the ventilation openings 11 enters the interior 12 of the clutch housing 5.
  • the longitudinal section in FIG. 5 and the view in FIG. 6 also show that the coupling housing 5 is provided with fastening holes 13 for retaining screws to be screwed into the core layer 4.
  • the vent openings 11 have a cross section in the form of a Kreisbo g enabschnit- tes, as shown in particular in FIG. 8.
  • the ventilation openings 11 can be designed as channels with a small cross section and a large length compared to their cross section.
  • FIGS. 12 to 14 shows a corresponding coupling element in which the ventilation openings 11 are formed within a frame 15.
  • this frame 15 parallel and spaced apart webs 16 are formed, which form the ventilation openings 11 between them.
  • the ventilation openings 11 are covered by a textile fabric 17, for example by a needle felt.
  • This needle felt can be seen in cross section in FIG. 12 and in a top view in FIG. 13. The needle felt has been omitted in FIG. 14 in order to be able to represent the ventilation openings 11 and the webs 16.
