Definitions

  • the present invention relates to a cold store according to the preamble of claim 1 protection.
  • Cold stores built using sandwich panels which in the present case include all types of cold stores, in particular cold stores for example, have been known for several years.
  • Sandwich panels are known plate-shaped components that can be used as raumabumblede and heat-insulating exterior wall and roof components, but also for interior design. They can be used directly as wall or roof elements or even only as a cladding.
  • Sandwich panels consist of a plurality of layers arranged one above the other and connected to one another, wherein the plurality of layers usually comprise an insulating layer, an upper covering layer arranged above the insulating layer, and a lower covering layer arranged below the insulating layer.
  • the insulating layer consists for example of rigid polyurethane foam, and the outer layers are made of sheet steel, for example.
  • Such sandwich panels have a width of up to about 3 m, a thickness of up to about 60 cm, and a length of up to about 25 m, and can be arranged side by side if necessary (to form larger areas).
  • mutually complementary profiles are provided on the mutually facing sides of adjacently arranged sandwich panels which can be inserted into each other.
  • Sandwich panels are now well-established standard products in industrial, roof and façade construction. They are available in a variety of sizes and embodiments and are, for example, from Romakowski GmbH & Co. KG, Herdweg 31, 86647 Butten submitted / Thürheim, Germany, from ThyssenKrupp Bausysteme GmbH, Hammerstrasse 11, 57223 funneltal, Germany, and from ArcelorMittal Construction GmbH, Oberer Str. 2, 06796 Brehna, Germany.
  • sandwich panels There are several ways to make a cold store using sandwich panels.
  • One of the options is to use the sandwich panels directly as space-enclosing and heat-insulating exterior wall and roof components, not just to cover existing wall or roof surfaces.
  • the sandwich panels more precisely the upper covering layer of the same, at the same time also form the outer skin of the cold store.
  • a support structure corresponding to the shape of the cold store is erected, and then the sandwich panels are fastened to the supporting structure by means of screws. Cold stores built in this way can be produced particularly quickly and inexpensively.
  • FIG. 1 A schematic representation of a support structure with attached sandwich panels is in the FIG. 1 shown.
  • the illustration shown is an external view of part of an outer wall of a cold store, in a state in which not yet all sandwich panels are attached to the support structure.
  • the support structure is designated by the reference numeral 1. It consists in the example considered of a plurality of juxtaposed vertical supports 11 and a plurality of stacked horizontal bars 12.
  • the supports 11 may for example have a mutual distance of 7 m, the bolt 12, for example, a mutual distance of 4 m.
  • sandwich panels 2-1, 2-2, and 2-3 are attached using screws.
  • the side profile 2-3-1 provided there is also visible on the right, onto which the profile of the adjacent sandwich panel designed to be complementary thereto is attached during assembly of the sandwich panel to be arranged on the right next to the sandwich panel 2-3.
  • the sandwich panels provided on the sandwich profiles in the intended composite state adjacent sandwich panels are no longer visible.
  • the sandwich panels and the fastening devices (screws) for fastening the sandwich panels to the supporting structure are subjected to high mechanical loads.
  • these loads include the weight of sandwich panels and external loads such as wind etc.
  • Agraffen are movable supports that allow a degree of relative movement between the sandwich panels and the supporting structure. As a result, it can not or at least not so quickly come to the formation of creases or the like damage.
  • the present invention is therefore an object of the invention to find a way by which a cold store can be made more simple and cost-effective than the mentioned clasps more resistant to the stresses occurring.
  • the sandwich panels are fastened to the supporting structure completely or at least partially by screws provided in the profile area, fewer screws are necessary for fastening a respective sandwich panel or the screws to be provided can have at least a larger mutual distance.
  • the sandwich profile is less strongly and / or weakened by the holes to be provided for the screws and thus is more resistant to stresses present in the sandwich panel or forces introduced therein, which in turn has the positive effect, This reduces the risk of wrinkling.
  • the screws by which the profile area of a sandwich panel is screwed to the support structure can be concealed by the adjacent sandwich panel and, moreover, a reduction in the number of screws to be provided overall is possible, the number of visible screws decreases, so that positive further effect improved protection of the screws from the weather and a more pleasing optical design of the cold store facade are possible.
  • cold store is understood to mean cold stores of all types, in particular cold stores, for example.
  • the sandwich panels are used directly as raumabumblede and heat-insulating exterior wall and roof components, so not only for the covering of existing wall or roof surfaces in the presented here cold storage.
  • the sandwich panels more precisely their outer layer, also form the outer skin of the cold store at the same time.
  • the presented here cold store has essentially the same structure as that in the FIG. 1 shown conventional cold storage.
  • FIG. 1 One of the FIG. 1 corresponding external view of part of an outer wall of the presented here cold storage is in FIG. 2 shown.
  • the supporting structure is in the FIG. 2 with the reference numeral 101, their supports with the reference numeral 111, their bars with the reference numeral 112, the sandwich panels with the reference numerals 102-1, 102-2, and 102-3, and the screws with the reference numerals 103 and 105th
  • the supporting structure 1 of the in FIG. 1 shown conventional cold store and the support structure 101 of the in the FIG. 2 shown novel cold store may be identical. To avoid Nederhol Institute is therefore on the corresponding statements FIG. 1 directed. It should be clear and requires no further explanation that there is no compelling need that the supporting structures are identically formed and dimensioned.
  • the peculiarities of the cold store presented here can also be used to advantage in refrigerated warehouses with other supporting constructions, for example, but not exclusively in the case of horizontal or vertical laying of the sandwich panels.
  • the sandwich panels 2-x of the in the FIG. 1 shown conventional cold store and the sandwich panels 102-x of the presented here cold store have many similarities.
  • the sandwich panels 102-x of the cold store presented here likewise consist of a plurality of layers arranged one above the other and connected to one another, wherein, as will be described in more detail below FIG. 3
  • the plurality of layers comprises an insulating layer 1021, an upper covering layer 1022 arranged above the insulating layer 1021, and a lower covering layer 1023 arranged below the insulating layer 1021.
  • the insulating layer 1021 consists in the considered example of rigid foam, such as polyurethane foam. But it could also be made of any other material with good heat insulating properties such as, but not limited to mineral wool, EPS, wood fiber, etc. exist.
  • the cover layers 1022 and 1023 arranged above and below the insulating material layer 1021 are composite-carrying parts which give the sandwich panel greater stability and moreover serve as protection against damage.
  • the cover layers 1022 and 1023 consist in the example considered of metal, for example made of sheet steel. However, the cover layers 1022 and 1023 can also of any other metallic materials, or of non-metallic materials such as a plastic, a fiber composite material, a wood material, etc. exist.
  • the joints between adjacent sandwich panels can be sealed by a film provided above. This film is not shown in the figures for reasons of clarity.
  • the sandwich panels have a width of up to about 3 m, a thickness of up to about 60 cm, and a length of up to about 25 m, and can be arranged side by side if necessary (to form larger areas).
  • complementary profiles are provided to each other, which can be stuck together.
  • the profiles are tongue and groove profiles; a possible shaping is in FIG. 3 shown.
  • the profiles are formed in the insulating layer 1021 and are at least partially closed by the upper cover layer 1022 and the lower cover layer 1023 to the outside. More specifically, the upper cover layer 1022 and the lower cover layer 1023 extend into the profile forming part of the sandwich panel and form there, at least for parts of the profile, an outer cover layer following the profile course (the protrusions and depressions of the profile) , The upper cover layer 1022 and the lower cover layer 1023 finally enter from the side of the sandwich panel into the insulating layer 1021 and end there after a few millimeters or centimeters.
  • the profiles are designed so that the profiles of juxtaposed sandwich panels in the assembled state are largely positively in contact with each other. As a result, a very good thermal insulation can also be achieved at the joint between adjacently arranged sandwich panels. At one point between the profiles of juxtaposed Sandwich panels, however, there is a cavity 1024, which will be discussed in more detail later. In addition, pockets for introducing sealing compounds for better sealing (for example, to achieve a better vapor-tightness) of the joints between adjacent sandwich panels may be provided.
  • the sandwich panels are also fastened to the supporting structure with the cooling house presented here using screws.
  • these screws are at least partially provided elsewhere than in the conventional cold store according to FIG. 1 the case is. More particularly, the sandwich panels are at least partially secured to the support structure using screws which penetrate the profile of at least one of two adjacent sandwich panels.
  • FIG. 3 shows a partial sectional view of the in the FIG. 2 shown arrangement, more precisely a section along a drawn in the figure line III-III.
  • the screws penetrating the profile of the sandwich panels are denoted there by the reference numeral 105.
  • the screw 105 is arranged so that its head comes to lie in the above-mentioned cavity 1024, or the cavity 1024 is provided where, in the intended assembled state of the adjacent sandwich panels 102-2 and 102-3 of the head of the screw 105th located.
  • the screw 105 is further arranged so that they no in the profile 102-2-1 provided recesses, in which when plugging the profiles 102-2-1 and 102-3-2 provided in the profile 102-3-2 projections must pass.
  • the profile 102-3-2 can be plugged onto the profile 102-2-1 without any obstructions.
  • the screw 105 is further arranged so that it passes through the parts of the upper cover layer 1022 and / or the lower cover layer 1023 extending into the profile area. It is not only permissible but even advantageous if it passes through the part of the upper cover layer 1022 extending into the profile area and / or the part of the lower cover layer 1023 extending into the profile area several times.
  • the screw 105 traverses the parts of the upper and lower cover layers 1022 and 1023 extending into the profile areas at least three times in total. In the example considered, there are even four times: as from the FIG.
  • the screw passes through 105 times the upper cover layer 1022 and two times the lower cover layer 1023, wherein each one of the crossings of the upper deck view 1022 and the lower cover layer 1023 in the protruding into the insulating layer 1021 end portions of the outer layers takes place, so that between the individual traverses areas of the insulating layer 1021 are located.
  • the sandwich panels 102-x of the presented here cold store are additionally attached in the example considered by screws 103 to the support structure 101, which the screws 3 of conventional cold storage according to FIG. 1 correspond.
  • the total number of screws 103 and 105 may be less than the total number of screws 3 of conventional cold stores according to the presented here cold store FIG. 1 , Depending on, inter alia, the size of the sandwich panels and the required strength of the attachment of the sandwich panels to the support structure may even be completely dispensed with the additional screws 103 under certain circumstances.
  • the sandwich panels are less strongly by the for perforated holes and correspondingly less weakened in their stability. The consequence of this is that the sandwich panels are much less susceptible to wrinkling or the like damage. This in turn makes it possible to attach the sandwich panels directly to the support structure, ie without the interposition of clasps or other devices that allow a relative movement between the sandwich panels and the support structure to the support structure.
  • the fact that less visible screws must be provided also has the very positive effect that sandwich panels with a larger width can be used for cold store construction.
  • the maximum width of the sandwich panels depends inter alia on the number of visible screws 3 and 103, respectively, which are to be provided for attaching a respective sandwich panel to each of the latches 12 and 112, respectively, to obtain the desired strong attachment to the respective latches , When in the FIG. 1 shown arrangement, this number is 3, because the sandwich panels 2-1 to 2-3 are screwed in each case by three adjacent visible screws 3 on each of the bolts 12; at the in the FIG. 2 As shown, this number is only 1, because the sandwich panels 102-1 to 102-3 are screwed to each of the latch 112 only by a single visible screw 103.
  • the sandwich panels are weakened by the screws used for fastening, more precisely by the boreholes provided for this purpose, the weakening of a respective sandwich panel increasing with increasing number of screws.
  • a weakening or at least a weakening in appreciable extent takes place only by the visible screws 3 and 103, respectively;
  • the concealed screws 105 penetrating the lateral profiles of the sandwich panels do not weaken the sandwich panels, or at least to a much lesser extent, because the sandwich panels are made particularly stable there by the greater number of metal layers arranged one above the other.
  • the weakening of the sandwich panels by the screws in general need not be considered separately. However, if the number of visible screws per bar becomes greater than three, it is necessary to separately check whether the weakening of the stability of the sandwich panels or the increased likelihood of wrinkling is within the limits that are still acceptable. If it turns out that this is no longer the case, the number of visible screws per bolt must be reduced. However, a reduction in the number of screws under otherwise unchanged conditions is generally not possible because the sandwich panels could then no longer be sufficiently strong attached to the support structure. A reduction in the number of screws must therefore generally be accompanied by a reduction in the width of the sandwich panels.
  • Narrower sandwich panels offer less impact surface to the wind and other external influences and can therefore be fastened to the supporting structure less strongly, ie with fewer screws. Due to the fact that the provision of the concealed screws 105 penetrating the lateral profiles of the sandwich panels allows the number of visible screws 103 to be reduced without sacrificing the strength of the attachment, there is the effect of an unacceptable weakening of the stability of the sandwich panels or an unacceptable likelihood of wrinkling is only at larger Sandwichpaneel widths than would be the case if the sandwich panels would be attached only by visible screws on the support structure. Furthermore, the case that a sandwich panel with more than three screws must be attached to each bar, only at larger widths occurs, so that only in rare exceptional cases then required special static calculations must be made.
  • the sandwich panels are used as the final outer wall and roof members, with the upper deck 1022 forming the outer surface of the cold store. It is, however It is also conceivable that the latches 112 and the supports 111, which together form the supporting structure 101, serve as the outer side of the cold store and the sandwich panels 102-1 to 102-3 are attached to the supporting structure 101 from the inside. This has the considerable advantage that the screws 105 are covered by the upper cover layer 1022, that no bacteria or other dirt can accumulate on them. This possibility is therefore most appropriate from a hygienic point of view.
