DETAILED DESCRIPTION OF THE INVENTION

(12) FIG. 1 shows a device according to the invention for the storage of objects under defined temperature conditions and humidity conditions, in particular for curing objects made of concrete. The device has a shelving system 1 and a climate system 2. Parts of the climate system 2 are also shown isolated in FIG. 2. The viewing direction in FIG. 2 is identical to the viewing direction in FIG. 1. The shelving system 1 has, in a region provided for the storage of objects, in the rear two rows of twenty-two columns each ten rows of twenty-two shelf supports each, which are referred to in FIG. 1 collectively by the reference numeral 3. The shelf supports 3 are used to support a plurality of shelves, which are not shown for reasons of clarity in the drawings. Further supports of the shelving system are provided in the lateral edge regions of the device which supports, however, like the supports 3 in the front two rows, do not support shelves. Cross braces for stabilizing shelving system 1 are located on the shelf supports or supports in the edge regions of said shelving system 1. In the head region of the shelving system 1, carrier elements for connecting the supports and shelf supports 3 are provided transversely to the rows in which the supports and shelf supports 3 are arranged, said carrier elements designated in FIG. 1 by the reference numeral 4.

(13) In the embodiment according to FIG. 1, a passage is arranged at both end faces of the rows of shelves, from which at least one carriage having shelves either for loading the shelves or for removing the shelves can move into the desired row. A time advantage arises during loading by loading from a passage and removal of the shelves to the passage on the opposite end face of the shelving system 1. In an embodiment according to the invention alternative to the embodiment shown, however, a passage is provided on only one end face of the shelving system 1, from which passage the shelves are fed for loading and through which the shelves having the cured objects leave the shelving system 1 again. This results in a smaller footprint of the shelving system 1 and cost advantages arise with the shelving system. 1

(14) The climate system 2 has an air conditioning unit 5 that draws in air through a return pipe system 6 and provides it with a desired temperature and desired humidity in a flow pipe system 7. The return pipe system 6 has a return collection channel 8. The flow pipe system 7 has a flow collection channel 9. The collection channels 8 and 9 extend in the head region of the shelving system 1 along the first two rows with the supports 3 of the shelving system 1. Numerous return collection channel connections 10 are provided on the return collection channel 8, by means of said return collection channel connections the carrier elements 4 are connected to the return collection channel 8. A flow distribution pipe 11 is arranged in each case parallel to each carrier element 4 and connected to the flow collection channel 9. Each flow distribution pipe 11 has in each case five or six flow distribution pipe connections 12, by means of which the flow distribution pipes 11 are connected in total to every second shelf support 3 and to every second support 3 in the second row. The flow distribution pipe connections 12 in this case are arranged offset from one another in such a way that in every row of the shelving system 1 with shelf supports 3 every second shelf support 3 and transverse to the rows along the respective flow distribution pipe 11, every second shelf support 3 is also connected to the flow pipe system 7.

(15) FIGS. 3, 4 and 5 illustrate parts of the device enlarged from different viewing directions. In FIG. 3, the viewing direction coincides with the viewing direction of FIGS. 1 and 2. In FIG. 4, the viewing direction is rotated by 90° with respect to FIGS. 1 to 3. In FIG. 5, the viewing direction is rotated by 180° with respect to FIGS. 1 to 3. For individual designation of the supports and shelf supports 3 visible in the figures, the reference numeral separated by a dot is a number of the row in which the respective support or shelf support 3 is arranged, and a number in the respective row is readjusted by a further point. FIG. 3 shows a section with the supports 3.01.09, 3.01.10, 3.01.11, 3.02.09, 3.02.10 and 3.02.11 with this notation. A number separated by a dot is added to the carrier elements 4, return collection channel connections 10 and flow distribution pipes 11 for individual designation, said number corresponding to the last number part of the associated support or shelf support 3. The flow distribution pipe connections 12 are marked individually according to the supports 3. Like reference numerals designate the same parts throughout these figures. The support 3.02.09 is connected to the flow distribution pipe 11.09 via the flow distribution pipe connection 12.02.09. In the same second row, the support 3.02.11 is connected to the flow distribution pipe 11.11 through the flow distribution pipe connection 12.02.11. Thus, the supports 3.02.09 and 3.02.11 are parts of the flow pipe system 7 of the climate system 2. The support 3.02.10 arranged between the supports 3.02.09 and 3.02.11, however, is not connected to the flow collection channel 9 and therefore not part of the flow pipe system 7.

(16) The carrier elements 4 are all parts of the return pipe system 6 and connected to the return collection channel 8 via the return collection channel connections 10. The carrier elements 4 in this case are C-profiles, which are closed by cover element 13. Three cover elements 13 are individually designated in FIG. 3 with the reference numerals 13.09, 13.10 and 13.11. In the crossing region with the supports 3 or shelf supports 3 which are not part of the flow pipe system 7, the carrier elements 4 each have an exhaust air opening, wherein an exhaust air opening is each provided in the rows and from row to row in the region of every second shelf support 3, in particular distributed like a checkerboard. Edge exhaust air openings are realized by means of first end caps 14, in particular first end caps 14.09, 14.10 and 14.11, at the ends of the carrier elements 4.

(17) FIG. 4 shows a detail of the device according to the invention, which again shows part of the detail shown in FIG. 3 from another perspective. In particular, upper sections of the supports 3.01.09, 3.01.10, 3.02.09 and 3.02.10 are also illustrated in FIG. 4. In addition, the detail shown in FIG. 4 shows upper sections of the supports 3.01.07, 3.01.08, 3.02.07 and 3.02.08. Also, the first end caps 14.07 and 14.08 are open and each have the function of an edge exhaust air opening. No exhaust air openings are arranged in the region of the supports 3 of the second row.

(18) At least the supports 3, which are part of the flow pipe system 7, that is, in particular the supports 3.02.07 and 3.02.09 each have a cover element 15, which is individually designated on the support 3.02.07 with 15.02.07 and on the support 3.02.09 with the reference numeral 15.02.09.

(19) FIG. 5 shows a detail with end regions of the flow distribution pipes 11.10 and 11.11. The flow distribution pipe 11.11 is connected to the shelf support 3.12.11 via the flow distribution pipe connection 12.12.11 so that supply air from the flow distribution pipe 11.11 can flow into the cavity formed by the shelf support 3.12.11 and covered by means of the cover element 15.12.11. As an alternative to the embodiment shown, all shelf supports 3.12 which are arranged at the edge of the shelving system 2, at the same time are also part of the flow pipe system 7 and lead supply air into the region near the bottom of the shelving system 1. The carrier elements 4 are mechanically connected to the shelf supports 3 of the last row. Second end caps 16 are arranged at the ends of the carrier elements 4. In this case, the second end cap 16.11 in the region of the shelf support 3.12.11, which is part of the flow pipe system 7, is closed. The second end caps 16.10 and 16.12, which are arranged in the region of the shelf supports 3.12.10 and 3.12.12, are open and each form an edge exhaust air opening. As an alternative to the embodiment shown, all end caps 16 are opened and each form an edge exhaust air opening. As a rule, that is, for example, with the exception of the first two rows shown according to FIGS. 3 and 4, a shelf support 3 is always in alternation at the same time a downward directed pipeline of the flow pipe system 7 or arranged adjacent to an exhaust air opening of the return pipe system 6.

(20) FIG. 6 shows a detail of the shelving system 1 in the foot region with the shelf supports 3.12.16, 3.12.17, 3.12.18 and 3.12.19. The viewing direction is the same as that of FIG. 5. The shelf supports 3 are not yet bedded in concrete in a base plate here. Therefore, a steel substructure 17 is visible in FIG. 6, which consists of a plurality of carrier rails 18 arranged parallel to each other and transverse to the alignment of the rows, of which the carrier rails 18 visible in FIG. 6 are designated by the reference numerals 18.16, 18.17, 18.18 and 18.19. Running rails 19 are preferably arranged pairwise on the carrier rails 18 between the rows of shelves and transversely to the orientation of the carrier rails 18. The running rails 19 are fastened on the carrier rails 18 by means of clamps. Carriages can be moved on the running rails 19 to load the shelving system 1.

(21) The shelf supports 3.12.17 and 3.12.19 are further formed by means of the cover elements 15.12.17 and 15.12.19 to pipes in which the supply air flows downward and can flow out through supply air openings 20, which are individually designated here by the reference numerals 20.12.17 and 20.12.19. The supply air openings 20 can be adjusted, wherein the throughput of supply air is adjusted by the supply air openings 20. The shelf supports 3 are fastened by means of angle plates and screw connections on the steel substructure 17. After the construction and alignment of the shelving system 1, the substructure 17 is cast into a base plate and is therefore no longer visible during operation of the shelving system 1. The entire steel substructure 17 and the running rails 19 are bedded with concrete by casting the base plate. The base plate thus produced counteracts a bending of the running rails 19, even when there is a carriage for loading the shelving system 1 on these rails 19.

(22) The carriage is in particular a loading device and can have a weight of several tons. The carriage preferably carries at the same time all shelves that are to be arranged one above the other in a section of the shelving system 1. All these shelves are stored at the same time on the bearing elements 21 provided for this purpose. After curing of the objects, all shelves respectively arranged one above the other are raised together again and moved with the carriage to one end of the respective passage. Preferably, after this, shelves having objects to be cured are again moved by means of the carriage into the region with the now free-standing bearing elements 21 and placed on these shelves. This is preferably done fully automatically.

(23) FIG. 7 shows a detail similar to the detail of FIG. 6, wherein, however, bearing elements 21 are fastened to the shelf supports 3.12.21 and 3.12.22 by means of screw connections. Centering aids 22, in particular board centering, center shelves on the shelf support 3.12.22, which shelves are to be placed on the bearing elements 21, when retracting.

(24) A plurality of bearing elements 21 can be seen in the sectional view of the device according to the invention having the shelving system 1 and the climate system 2 according to FIG. 8. A detail designated “S” from the illustration of FIG. 8 is illustrated enlarged in FIG. 9.

(25) A detail designated “R” having two identical bearing elements 21 in FIG. 10, of which to distinguish bearing elements only a first bearing element is designated by reference numeral 21 and the second bearing element by the reference numeral 21′, is shown enlarged again. Each bearing element 21, 21′ is a multi-angled and galvanized steel sheet, which has from bottom to top next to each other a not further designated slope, a lower contact surface 23 adjoining the slope in an edge, an oblique support surface 24, a planar bearing surface 25, an oblique connection surface 26, an upper contact surface 27 and a chamfer 28. The chamfer 28 has an oblique surface, which is aligned parallel to the oblique support surface 24. The chamfer 28 subsequently has a vertical surface, which is arranged parallel to the contact surfaces 23 and 27, and a horizontal surface, which is arranged parallel to the planar bearing surface 25.

(26) All the features mentioned in the preceding description and in the claims can be combined in any selection with the features of the independent claim. The disclosure of the invention is therefore not limited to the described and/or claimed combinations of features, but rather all feature combinations meaningful in the context of the invention are to be regarded as disclosed.
