Description

The present invention relates to a heat storage plate for use in rack stores having a plurality of storage levels and to a rack store equipped with at least one heat storage plate of this type.Rack stores with a plurality of storage levels arranged one above the other are frequently used in warehouses, in which, however, the individual storage levels comprise, in addition to the actual placement regions or shelf compartments for objects to be accommodated, also perforations through which, for example, latticework struts or similar components are guided.However, this results in the problem that warm air can rise relatively easily in directions from higher levels through the corresponding recesses in the bearing planes, which can lead to dangerous situations, in particular in the event of a fire. In this case, in rack stores of this type and in particular pallet racks, it is frequently required as a fire protection measure that corresponding sprinkler systems are provided, which, in the event of a fire and a detection of such a situation associated therewith by a fire detector, immediately and automatically trigger a corresponding extinguishing process.However, in such cases, due to the above-mentioned recesses in the individual bearing planes, not only does there be the risk of a direct flame penetration from lower to higher planes, but it can also happen, by providing these recesses, that the heat that arises is not sufficiently built up to trigger the corresponding fire detectors or sprinkler heads.Accordingly, it is frequently likewise required that the individual bearing planes, usually via the sprinkler lines mentioned, are covered with so-called heat-retaining plates. This ensures that not only is the actual storage surface of the shelf compartments covered, but also the stand region already mentioned with diagonal shelf struts or other objects running therein, which may be provided therein, which, however, means an increased structural outlay, since suitable means must provide the possibility of guiding the corresponding objects through the heat-accumulating plates.For this purpose, it has been proposed, for example, in DE 20 2020 104310 U1 to form a heat accumulation cover unit for covering an opening surface between adjacent shelf compartments in a shelving system with at least two cover plates, wherein at least one central plate enclosing or enclosing a support strut is furthermore provided. These plates can be fastened accordingly via rivet connections.Reference is also made to DE 20 2020 101335 U1, which teaches a metallic lattice structure compartment base with a heat storage plate for a rack installation of a goods store, wherein the heat storage plate has at least two parallel embossed beads, which emboss ribs and are welded to the lattice structure at crossing points.It is also known to provide sheet metal strips on corresponding rack stores, which enclose the latticework struts and can likewise be fastened via rivet connections. However, this results in increased assembly effort due to necessary adaptation work on site and sometimes also mechanical separation work at high working heights. In addition, an increased use of material is to be expected due to the inevitably occurring waste and necessary trimming operations may not be permitted in corresponding protective areas. It is also shown that in the event of damage individual work on site may be necessary, since the described solutions are not a standardized system.Accordingly, there is a need for a simply constructed, assembly-friendly and modular system which is suitable for being able to cover open spaces in rack stores, even in the region of diagonal truss struts or other objects present there, in accordance with requirements. It is also desired that a corresponding solution is flexible enough to be able to handle the high variances of the corresponding rack stands, rack compartment dimensions and rack types which occur in practice, in order to be able to be used, inter alia, in pallet racks, cantilever racks, shuttle racks, continuous racks, slide-in racks, entry racks, collie racks, rack racks, wide-span racks and shelf racks.In order to solve this object and to eliminate the above-described disadvantages of the known prior art, the invention proposes a heat baffle plate for use in rack stores having a plurality of storage levels, which comprises a body section having a longitudinal direction and a width direction, which span a body level, at least one mounting section provided on the body section for mounting on a corresponding rack compartment, and a comb region provided on the body section, with respect to the width direction, opposite the at least one mounting section, having a plurality of comb sections, which are configured to be capable of being bent individually out of the body level in each case.By means of this construction, it is possible to cover corresponding recesses in shelf surfaces and, in the region of diagonal truss struts or other objects running in the recesses, to bend the corresponding comb sections out of the plane of the heat plate in order to create corresponding complementary free spaces in the plane to be covered. In other words, the function of the comb sections is that incisions are inserted in the comb region of the heat-absorbing plate according to the invention, which cuts make it possible, at a corresponding interfering contour, such as the diagonal truss struts already mentioned, to bend over a suitable number of the plurality of comb sections of the heat-absorbing plate.According to the invention, the body section and the comb region can be formed integrally with its comb sections, in particular from a single metallic sheet metal part. Alternatively, however, it would of course also be conceivable to provide the body portion and the comb portions or the comb region by means of two separate components connected to one another, which can be connected for example by means of riveting or screwing, so that in such embodiments the comb region would be riveted or screwed to the body portion.As already indicated further above, the comb sections can each be separated from their adjacent comb sections by cuts or perforations, whereby in both cases a respective bending of individual comb sections or of a plurality of adjacent comb sections is made possible. The individual configuration of the cuts with respect to their width defines a remaining passage cross section through the heat baffle plate, which, however, can be made substantially arbitrarily small in the case of a suitably narrow configuration of the cuts. In the case of perforations being provided between adjacent comb sections, care must also be taken that these perforations weaken the material far enough that, when a corresponding heat baffle is installed, simplified bending of the corresponding comb sections still remains possible, since in this case firstly a physical separation of comb sections to be bent over from comb sections not to be bent over must be brought about by an engineer.Furthermore, for simplified installation of a heat baffle plate according to the invention, respective weakening regions can be provided in the transition regions between the body section and the comb sections, in particular perforations, perforations and / or regions with reduced material thickness, in order to facilitate bending of the comb sections with respect to the body section. Accordingly, the above-mentioned modifications in the transition regions each define a desired predetermined bending point which will facilitate a technician of the heat-absorbing plate the corresponding bending of the comb sections.While in principle any types of mounting sections can be provided in the heat-absorbing plate according to the invention, for example, a screw connection of the heat-absorbing plate to a rack bearing by means of suitable screw / thread pairs or riveting is also conceivable, in an embodiment which is particularly easy to mount, the at least one mounting section can be formed by at least one mounting projection which extends from the body section in the width direction and which is bent or bendable with respect to the body section. Such a mounting projection is accordingly to be inserted into an opening, such as an elongated hole, to be provided on the rack store, whereby tilting or jamming of the heat storage plate on the rack store is made possible in a tool-free and simple manner.In this case, in particular the bending of the at least one mounting projection with respect to the body portion can describe a Z-shaped curve, so that the heat baffle will itself hold itself in position and no further fastening to adjacent elements is required. Alternatively or additionally, a plurality of mounting projections spaced apart in the longitudinal direction of the body section can also be provided in order additionally to exclude undesired tilting of the heat baffle from the outset.According to the features and possible developments discussed here of the heat baffle plate according to the invention, it is evident that this not only enables simple and reliable assembly and startup, but can also be used independently of the rack types and variants used together therewith. Accordingly, a universally usable solution for the above-mentioned technical task is created, which is distinguished in the manner mentioned by its simplicity, ease of assembly and the associated low costs.Furthermore, the present invention relates to a rack store having a plurality of storage levels, comprising a plurality of rack compartments forming the storage levels, which compartments are broken through in sections by recesses, and at least one heat-absorbing plate of the type according to the invention described above, which is mounted on one of the rack compartments in such a way that the comb section and, if appropriate, at least in sections the body section extend over the corresponding recess, wherein the comb sections lying in the region of objects located in the recess are bent out of the level of the remaining comb sections.As already mentioned, the mentioned recesses can be stand regions in which diagonal truss struts extend, which accordingly correspond to the objects likewise just mentioned.Furthermore, in the case that the at least one heat baffle plate is formed with at least one mounting projection in the manner described above, at least one elongated hole can be assigned to the corresponding bearing plane, which elongated hole is configured to receive the at least one mounting projection.Finally, it should also be pointed out that although in some embodiments of the invention a corresponding recess can already be covered by means of a single heat-storage plate, in alternative variants, however, at least two heat-storage plates can also be provided in a rack store, which are opposite one another for covering a single recess. Accordingly, the two heat-retaining plates mentioned extend toward one another from both sides of the recess from respective edges of the corresponding shelf surface and meet centrally above the recess, optionally at a small distance, which likewise contributes to the remaining residual passage cross section of the recess and therefore should preferably be selected to be small.Further features and advantages of the present invention will become more apparent from the following description of an embodiment thereof when taken in conjunction with the accompanying drawings. These show in detail: FIG. 1 shows a top view of a heat baffle plate according to the invention; FIG. 2 shows the heat baffle plate from FIG. 1 during its mounting on a rack compartment in two isometric views, FIG. 3 shows the mounting process from FIG. 2 in two cross-sectional views; FIG. 4 shows an isometric view of a rack storage device according to the invention, comprising two heat-accumulating plates according to FIG. 1 ; FIG. 5 is an enlarged view of a portion of the rack storage of FIG. 4 ; and FIG. 6 shows a detailed view of the heat-accumulating plates of the rack store from FIG. 4.In FIG. 1, a heat baffle plate according to the invention is first shown in a plan view and is denoted quite generally by the reference sign 10. It comprises a body section 12 having a longitudinal direction L and a width direction B, which together span a body plane, which is viewed exactly perpendicularly in the view of FIG. 1.Further, the heat-shielding plate 10 includes a mounting portion 14 provided on the body portion 12 which is formed by a total of three mounting protrusions 14 ato 14 cthat extend away from the body portion 12 in the width direction B. In this case, the mounting projections 14 ato 14 care bent out of the body plane in sections, as will be explained in more detail further below in connection with FIGS. 2 and 3.In addition, the heat-accumulating plate 10 comprises a comb region 16 provided opposite the mounting portion 14 in one piece with the body portion 12 with a plurality of comb portions 16 ain relation to the width direction B. The comb sections 16 aare each separated here by cuts 16 b, which are formed very narrow in the longitudinal direction L compared to the extent of the comb sections 16 a, so that the comb region 16 has only a very small passage cross section with respect to its total area, as can be seen in the plan view from FIG. 1.Furthermore, respective weakening regions 16 care provided in the transition regions between the body section 12 and the comb sections 16 a, which in the exemplary embodiment shown here are each likewise formed by perforations and which simplify bending of the individual comb sections 16 awith respect to the body section 12 out of the body plane.With reference to FIGS. 2 and 3, the process of mounting the heat storage plate 10 on a shelf compartment 102 of the shelf storage device 100 described further below in connection with FIGS. 4 to 6 will now be explained.It can be seen in FIG. 2 that the shelf compartment 102 is assigned three elongated holes 104 ato 104 cin its edge region, which correspond to the mounting projections 14 ato 14 cof the heat storage panel 10 according to their dimensions and spacings. Thus, insertion of the heat baffle 10 into the shelf surface 102 is permitted for mounting thereto, as is evident from the transition of the upper to the lower figures in FIGS. 2 and 3, respectively.Further, since the mounting portions 14 ato 14 cdescribe a Z-shaped curve with respect to the body portion 12 of the heat-shielding plate 10, as best seen in the cross-sectional view of FIG. 3, the heat-shielding plate 10 will jam on the shelf surface 102 in a state in which the ridge portion 16 and a part of the body portion 12 project in extension of the shelf 102. This state is shown in FIGS. 2 and 3 in the lower figure. Accordingly, the heat-storage plate 10 will form an extension of the shelf compartment 102 beyond its left-hand end in FIG. 3 and can in particular cover a recess to a further section of the shelf compartment 102 which is not shown here and is adjacent to the left.Such a condition is illustrated in Figure 4 wherein a portion of the storage shelf 100 is shown in isometric view. This rack store 100 comprises a plurality of storage levels, of which, however, only the already mentioned rack compartment 102 can be seen in the view selected here, which is perforated by the already indicated recess 106 in the form of a stand region, such that two parts 102 aand 102 bof the rack compartment are provided with the recess 106 therebetween. A diagonal truss 108 now extends in this stand region 106 and extends obliquely between mutually opposite rack uprights 110 in order to impart increased stability to the rack store 100 in this way.In order to be able to cover the recess 106 for fire protection reasons and in this case still to allow the diagonal truss 108 to pass through, two heat-blocking plates 10 of the type described above and shown in FIGS. 1 to 3 are mounted opposite one another, as is evident in particular from the enlarged view from FIG. 5. The two heat-accumulating plates 10 are attached and clamped in the manner described above on both sides of the recess 106 to the mutually opposite parts 102 aand 102 aof the shelf 102 by means of their mounting sections 14.It can be seen in FIG. 5 that accordingly the recess 106 is almost completely covered by the two heat-retaining plates 10 and only a narrow distance between the two heat-retaining plates 10 and the notches 16 bprovided therein remain as an effective passage region for air.Finally, reference is now made to FIG. 6, which shows, in an isometric view from obliquely below, that region of the recess 106 in which the diagonal truss strut 108 extends obliquely through the recess 106. It can be seen here that a number of comb sections 16a' have been bent downward out of the body plane in order to allow the diagonal truss member 108 to pass between the remaining comb sections 16a, which are not bent and accordingly continue to lie in the body plane of the heat baffle 10.It can also be seen in FIG. 6 that the diagonal truss 108 does not extend centrally through the recess 106 but is displaced in the direction of the right-hand part 102 aof the shelf 102 in FIG. 5. Accordingly, a corresponding bending of the comb sections 16a' has become necessary even in the case of only the right-hand one of the two heat-storage plates 10, while the comb sections 16a of the left-hand heat-storage plate 10 in FIG. 5 can all remain non-curved, which does not, however, impair the functioning thereof in any way.References included in the specificationThis list of documents cited by the applicant has been produced in an automated manner and is only included for the better information of the reader.
