Definitions

  • the invention relates to thermal insulation for cold stores, cold rooms and cold rooms according to the preamble of claim 1.
  • Cold stores are mostly insulated with thermal insulation elements made of rigid polyurethane foam in the form of plate-shaped wall elements, with which the walls and ceiling of the cold stores are clad.
  • the plate-shaped wall elements are placed against each other so that joints remain between adjacent wall elements that have to be closed.
  • the grouting is at least 40 km and more.
  • these joints are closed by a sealing profile, which is made in one piece from plastic and is formed from an L-shaped or T-shaped web with an adjoining cap.
  • corresponding recesses or grooves are formed on the end faces of the wall elements in which the sealing profiles with their L or T legs are loosely arranged.
  • the sealing profile with its L- or T-shaped part is first inserted into the corresponding recess in the end face of the wall element before the adjacent wall element can be connected.
  • the adjacent wall element must be attached so that the L or T leg of the pre-assembled sealing profile comes into the corresponding recess of the wall element to be connected, whereby care must also be taken that the outer surface of the wall element is inserted in front of the cap and fitted exactly between the L or T leg of the sealing profile and the underside of the cap becomes. This requires appropriate care and sensitivity of the personnel who create the thermal insulation of the cold store, damage to the thermal insulation elements should be avoided.
  • the gaps between the sealing profiles and the wall elements placed against one another must then be filled with a permanently elastic joint compound, for which purpose silicone is used in particular.
  • a joint seal is achieved with this permanently elastic mass, but silicone in particular has the disadvantage that it absorbs spores, so that fungi can form.
  • the penetration of spores also leads to a discolouration of the silicone mass, so that over time the outside of the thermal insulation no longer offers an optically perfect appearance.
  • the walls of the cold stores have to be cleaned periodically, which is done by high-pressure cleaners.
  • the object of the invention is to provide thermal insulation for cold stores which is free from the disadvantages described above.
  • the thermal insulation according to the invention should be characterized in that the thermal insulation can be created more quickly and easily and in a material-saving manner by facilitating the jointing.
  • an excellent sealing of the joints of adjacent thermal insulation elements should be guaranteed in a hygienically perfect manner.
  • the sealing profile is formed from two parts which can be plugged together, namely a base part and an impact profile.
  • a base part and an impact profile.
  • the drive-in profile can be driven in from the outside under pressure on the base part already in the joint.
  • the locking position for the turning profile in the base part is chosen so that the cap is under pressure bears on the outer surface of the adjacent wall elements, so that a seal of the joint to the outside is ensured as a result of the cap which is pressed against it.
  • the cap is expediently formed with downwardly projecting sealing lips on both sides of the joint, which run continuously along the underside of the cap. Since the drive-in profile is made of plastic, the cap ends can deflect resiliently behind when the plug-in strip is turned in, so that in the assembled position the cap ends with the protrusions formed on the underside pretension the outer surface of the adjacent wall elements.
  • the projections on the cap are expediently formed by sealing lips which are angled downwards from the plane of the cap and extend outward from the cap.
  • these sealing lips are pressed somewhat backwards, so that they then bear under pressure with their expediently rounded end edges along the joint on both wall elements in a sealing manner.
  • the distance from the upper edge of the leg of the base part to the lower edge of the cap is smaller than the thickness of the thermal insulation between the groove and the outer surface of the thermal insulation, this difference being approximately 2 to 3 mm in an advantageous embodiment. This ensures that the sealing lips are adequately sealed even in the event of any tolerance deviations in the components used.
  • This resilient backward bending of the sealing lip is further promoted if the sealing lips are connected in the manner of a joint to the turning profile, which is done in a technically simple manner in that longitudinal grooves are made in the transition region of the sealing lip to the turning profile.
  • the conventional thermal insulation shown in Fig. 1 consists of butted wall elements 1, the butt joints 2 on the two outer sides of the thermal insulation are closed to the outside by sealing profiles 3. 1, these sealing profiles 3 are formed in one piece from an L-shaped web 4 and a cap 5 connected thereto, which has projections 6 formed on the underside adjacent to its two longitudinal edges, with which the cap rests on the longitudinal edges of the two thermal insulation elements 1.
  • the strip-like sealing profile 3 is loosely received in grooves 7 made on the end faces of the thermal insulation elements 1.
  • thermal insulation element 1 To assemble the thermal insulation is according to Placement of a thermal insulation element 1 first the sealing profile - or in the case of jointing on both sides, both end profiles - inserted into the corresponding groove 7 of the end face. Then the second thermal insulation element 1 is pushed laterally against the first thermal insulation element 1, care being taken that the thermal insulation element 1 gets in front of the underside of the cap and the L-leg of the web 4 of the sealing profile is not pressed out of the groove.
  • This assembly requires a corresponding care of the operating personnel, in particular when both outer sides of the thermal insulation have to be grouted at the same time by means of appropriate sealing profiles.
  • a permanently elastic joint compound in particular silicone, is introduced into the remaining gaps between the sealing profile and the thermal insulation elements.
  • the embodiment of a sealing profile 8 shown in FIG. 2 is formed in two parts and consists of a base part 9 and an impact profile 10.
  • the impact profile 10 is designed such that it can be driven into the base part 9.
  • the base part 9 is arranged in the grooves 7 of the adjacent wall elements 1 and is loosely seated within the grooves 7. Because of the division in two, assembly is extremely simple, because after arranging the base part 9 in a groove 7 of the one wall element 1, the other is only pushed on laterally got to. Then the impact profile 10 is pressed in from the outside.
  • the turning profile has a cap 11, from which a plug-in strip 12 projects vertically downward, at the free end of which a catch 13 is formed, which in the exemplary embodiment shown has the shape of an arrowhead.
  • Base part 9 protrudes from the plane of the two legs 14, a receiving web 15, which is formed from two opposite walls 16 and 17, which form a groove-shaped receiving space 18 between them for the projecting part 12 of the impact profile 10.
  • the two walls 16 and 17 have catch projections 19 arranged opposite one another at their upper end, which delimit an inlet zone 20 which has an arrowhead shape between them and end in a recessed shoulder 21 which provides a catch surface for the catch 13 represents.
  • the locking projections 19 formed with an inclined surface and the recessed shoulder form the locking member for the locking 13.
  • the cap 11 of the impact profile 10 has a sealing lip 22 on each of its two longitudinal edges, which in the exemplary embodiment shown tapers towards its free end and the tip of which is rounded.
  • the sealing lip 22 is connected in an articulated manner, which takes place by means of molded-in longitudinal grooves 23 in the region of the longitudinal edges.
  • additional lips 26 are provided in the embodiment according to FIG Lie on the outer surface of the thermal insulation element 1.
  • the sealing lips 22 are horizontal, i.e. H. the plane of the cap 11, angled downwards by an angle of approximately 30 °, whereas the more angled additional lips 26 are angled downwards by an angle of approximately 60 °. Furthermore, the additional lips 26 protrude slightly downward over the lower edges 25 of the sealing lips 22. Furthermore, the catch 13 does not represent the free end of the web-shaped plug-in strip 12, rather a web-shaped cut-off 27 adjoins the catch 13 at the bottom, which is received between the two longitudinal walls 16 and 17 below the catch surface 21.
  • the base part 9 and the impact profile 10 are made of plastic and are strand-shaped, so that the sealing profiles can be laid in strips between the joints. Since the sealing contact of the sealing lips is correspondingly large due to the preload, no additional grouting is required due to a permanently elastic mass.
