Abstract

The invention relates to a device for storing objects under defined temperature and humidity conditions. In particular, the invention relates to a device for hardening objects made of concrete. The device has a shelf system with a plurality of shelf supports and a plurality of support elements which are supported on the shelf supports and are arranged one above the other in a plurality of levels, for supporting shelves on which the objects are stored. According to the invention, a flow pipe system for distributing supply air provided in an air conditioning system is at least partially integrated into the shelving system. Several shelf supports are at least in sections at the same time downwards of the supply air through which the supply pipe system can flow. This counteracts the formation of condensation on the base of the shelf system and thus corrosion on the shelf supports, so that the shelf life of the shelf system is increased.

Description

The invention relates to a device for storing objects under defined temperature and humidity conditions according to the preamble of claim 1. In particular, the device for hardening objects made of concrete is provided. The objects are, in particular, paving stones, concrete blocks, sidewalk slabs or cantilever stones, which are made in large numbers from concrete and, after hardening, should have properties that are as similar as possible to a largely identical appearance and largely identical strength. This can be achieved by curing together under defined temperature and humidity conditions. Compared to uncontrolled hardening objects made of concrete, the duration of hardening can be reduced to 24 hours, for example. At the same time, fewer binders, such as cement, can be used for the concrete, since the existing binder is converted almost optimally with the set moisture. The objects hardened under suitable defined conditions also have a higher strength than uncontrolled hardened objects made of concrete.

A known device of this type for hardening concrete blocks has a shelving system, provides supply air with defined temperature and humidity conditions and, for this purpose, has an air conditioning system for providing the supply air and a feed pipe system for distributing the supply air provided in the air conditioning system. The shelf system has a plurality of shelf supports and a plurality of support elements supported on the shelf supports and arranged one above the other in several levels for supporting Shelves on, the objects to be hardened are stored on the shelves.

In this known device, the supply air is distributed in the head region of the rack system with pipes and from there through several vertically arranged pipes of the supply pipe system into the foot region of the rack system. Exhaust air is extracted in the head area of the shelving system. The air thus rising along the stacked shelves creates largely the same temperature and humidity conditions at different levels of the shelf system.

Very high air humidity is advantageous for the hardening of concrete. This leads to a high dew point temperature and consequently to the fact that water from the supply air already condenses on parts of the shelving system if these parts are only slightly cooler than the supply air. In particular, it has been shown that moisture condenses on the shelf supports in the foot area of the shelf system, that is to say in an area in which the shelf supports are concreted into a base plate. In this area, the shelf supports are conventionally cooler than in higher areas of the shelf system.

The shelf supports are usually galvanized, which provides a shielding effect and an additional active corrosion protection by acting as a sacrificial anode. Nevertheless, the permanent exposure to moisture results in a shortened life of the corrosion protection and thus the risk of corrosion on the shelf supports, which are load-bearing parts of the shelf system.

The invention has for its object to protect the shelf supports on their feet from corrosion for a longer period of time and thus to increase the life of the shelf system.

The invention solves this problem with a device for storing objects under defined temperature and humidity conditions according to claim 1. Further advantageous refinements of the invention are specified in the subclaims.

In the case of a device for storing objects, in particular for hardening objects made of concrete, under defined temperature and humidity conditions, with a shelf system which has several shelf supports and a plurality of support elements which are supported on the shelf supports and are arranged one above the other in several levels for supporting shelf floors on which the objects are stored, it is provided according to the invention that a feed pipe system for distributing supply air provided in an air conditioning system is at least partially integrated into the shelving system, with several shelf supports at least in sections at least at the same time downward flowable pipes of the feed pipe system from which the supplied air can flow.

The invention initially recognized that there is improved corrosion protection if the shelf supports are also kept above the dew point temperature in the base area of the shelf system. Furthermore, the invention has recognized that an increase in the temperature of all shelf supports in the foot region of the shelf system is achieved if the supply air is directed to the floor at close intervals and there heats up the floor plate over a large area.

The invention has also recognized that shelf supports are also heated in the foot area when the supply air is passed through these shelf supports and that the base plate is thereby heated so uniformly that adjacent shelf supports through which no supply air is also guided also a temperature above the dew point temperature take in. In particular, the invention uses the shelf supports, which are provided at close intervals, as pipelines for the supply air, which is conducted with the feed pipe system into the foot region of the shelf system.

The shelf supports are arranged so close that it is sufficient and preferably provided that only every second shelf support is used as the pipeline of the feed pipe system. The shelf supports, through which the supply air flows, are heated directly. The shelf supports through which the supply air does not flow are so close to the shelf supports through which the supply air flows that sufficient heating of all the shelf supports also takes place in the foot area of the shelf system. In particular, each shelf support not flowed through by supply air has at least one adjacent shelf support, which at the same time is a pipeline of the supply pipe system and is therefore heated by the supply air and also sufficiently heats the adjacent shelf support. At the edges of the shelf system, each shelf support or other support is preferably flowed through by supply air and thus at least in sections at the same time a pipeline of the supply air pipe system. This ensures sufficient heating of the base plate in the edge areas of the shelf system. Between the edges, shelf supports through which supply air flows and shelf supports that are not part of the supply air pipe system are arranged in a checkerboard fashion.

Thanks to the invention, the life of the device is increased. At the same time, even more uniform conditions, in particular for the hardening of concrete, are created at the individual parking spaces for the objects in the shelving system, which further increases the quality, in particular the pressure resistance, the abrasion resistance and the color uniformity, of the hardened concrete objects. The concrete objects are, in particular, paving stones, concrete blocks, pavement slabs or edging stones.

All shelf supports of the shelving system are preferably made of galvanized steel. At least the shelf supports, which at least in sections are at the same time downwards of the supply air system through which the supply air can flow, preferably each have a C-profile with an open side. This open side is preferably at least in the sections in which the respective shelf support at the same time a pipe of the flow pipe system is closed by means of a cover element. The cover element is preferably a sheet metal profile, in particular a piece-galvanized sheet metal profile. The C-profile together with the cover element ensures that the pipeline of the flow pipe system is completely closed. The supply air is preferably fed to the shelf supports through separate pipelines which are laid approximately at the level of the support elements.

In a particularly preferred embodiment of the invention, it is provided that the supply pipe system has a plurality of supply air openings arranged in the foot region of the rack system and each formed in a rack support for blowing out the supply air from the supply pipe system. In particular, such a supply air opening is provided at the foot of each shelf support, which is designed in particular to allow the supply air to flow onto a base plate on which the shelf system is built. The supply air flowing out of the supply air openings is in particular heated and therefore warms the base plate.

The supply air openings preferably each have an adjustable opening width. As a result, adjustments can be made after the initial start-up of the device in order to achieve a distribution of the supply air, which leads to a uniform temperature and air humidity in all areas of the shelving system.

The shelf system advantageously has a plurality of support elements which connect the shelf supports to one another in the head region of the shelf system. The carrier elements are preferably all made of galvanized steel. It is particularly preferably further provided that a return pipe system for returning exhaust air is at least partially integrated into the shelving system. Several carrier elements are at the same time exhaust pipes through which the return pipe system can flow. In particular, the air is circulated through the room in which the shelving system is arranged, guided. The air is blown into the room as supply air through the supply pipe system and extracted from the room as exhaust air through the return pipe system. After appropriate treatment of the exhaust air, that is, after adjustment of the temperature and preferably also the air humidity, the extracted exhaust air is fed back into the supply pipe system as supply air. A further exhaust air device is optionally provided for extracting exhaust air into the environment.

At least the support elements, which are at the same time pipes of the return pipe system through which the exhaust air can flow, each have a C-profile with an open side. This open side is advantageously closed by means of a cover element, at least in the sections in which the respective carrier element is at the same time a pipe of the return pipe system. The cover element is preferably a sheet metal profile, in particular a piece-galvanized sheet metal profile. The air routing of the exhaust air in the carrier elements takes place in particular in accordance with the air routing of the supply air in the shelf supports.

According to an advantageous embodiment of the invention, the return pipe system has a plurality of exhaust air openings arranged in the head region of the rack system for sucking the exhaust air into the return pipe system. The exhaust air openings are arranged in particular in the open sides of the carrier elements following a respective cover element. An inlet air opening is preferably arranged on every second shelf support in the foot region and an exhaust air opening is arranged in the head region of every second shelf support, which is a shelf support without an inlet air opening. This results in a dense network of supply air openings and exhaust air openings and a largely even upward flow across the surface of the shelving system past the shelves.

The device according to the invention with the flow pipe system partially integrated into the shelf system can also be used like a commercially available one Shelf system can be used without the supply pipe system being supplied or can be supplied with supply air, in particular without the supply pipe system being part of an air conditioning system. The device according to the invention can also be combined with an existing air conditioning system or with parts of an existing heating system, if necessary also if necessary. However, it is preferably provided that the device for storing objects also has the air conditioning system.

The air conditioning system preferably has at least one air conditioning unit for providing the supply air with a temperature that can be created or for providing the supply air with a temperature that can be created and with a humidity that can be created. The exhaust air from the return pipe system is preferably supplied in whole or in part to the air conditioning unit on the input side. The air conditioner is preferably designed to heat the supply air and optionally also to humidify it. The air conditioning unit is also advantageously designed to dehumidify the supply air. Alternatively or additionally, the air conditioner is also designed to cool the supply air. This allows the air conditioner to provide the supply air with the desired temperature and humidity. The different functionalities for air conditioning are either structurally distributed over several devices or completely or partially combined in at least one air conditioning device.

The air-conditioning system preferably has a control which controls the at least one air-conditioning unit in such a way that the temperature and humidity of the supply air keep the temperature and humidity in the region of the shelving system in a predetermined range. For this purpose, at least one temperature sensor and at least one moisture sensor are preferably provided in the region of the shelf system. The sensors provide the control system with measured values. The control unit controls the air conditioning unit on the basis of these measured values. In particular, the climate system is used to maintain a temperature in the region of the shelving system in a range between 20 ° C and 40 ° C, in particular between 30 ° and 40 °. educated. Advantageously, the air conditioning system is also used to maintain a humidity level in the area of the shelving system of more than 40%, preferably more than 60%, more preferably more than 90%, in particular in a range from 94% to 97% or from 95% to 96 %, educated. Corresponding climate values have proven particularly useful for hardening concrete. In an alternative embodiment of the invention, the moisture control, including the moisture sensor, is omitted.

The device according to the invention is particularly preferably designed for hardening concrete. The objects to be stored in the shelving system are made of concrete or have concrete. For example, shelves with concrete blocks are stored in the shelf system shortly after the production of the concrete blocks, where, thanks to the climate provided by the invention, the concrete blocks harden within a short time to such an extent that they can be removed from the shelf system after 24 hours and, for example, in a further treatment can be shot peened. Immediately afterwards, the shelving system can be refilled with additional concrete objects to be hardened. In the area of the shelving system, there is almost always a climate that favors corrosion in principle. Thanks to the invention, however, the formation of dew on the feet of the shelf supports is effectively counteracted, so that an advantageously extended lifespan and useful life of the shelving system is achieved.

The shelving system preferably has a steel substructure. The shelf supports are supported on this steel substructure. The steel substructure is preferably cast into a base plate. The base plate is cast in particular from liquid screed. The shelf supports protrude from the base plate. Before the base plate is cast, the steel substructure is leveled in order to later achieve a horizontal alignment of the shelves.

In a preferred embodiment of the invention it is provided that rails are also fastened to the steel substructure. Carriages for the transport of the shelves to be supported on the support elements with the objects to be stored in the shelving system can travel on these rails. The rails should be level. Thanks to the fastening of the rails on the steel substructure, the rails are inevitably aligned horizontally when the steel substructure is aligned horizontally. So it only needs to be leveled once. The rails are preferably attached to the steel substructure by means of clamps.

Conventionally, known support elements for supporting shelves are hung in known shelf supports, which have a large number of holes for this purpose. In an advantageous embodiment of the invention, on the other hand, it is provided that the support elements according to the invention are screwed onto the shelf supports for supporting the shelves. The shelf supports are preferably closed at least in sections against which the support elements bear, that is to say they are designed without holes for hanging support elements. As a result, the shelf supports can be used particularly advantageously as pipelines through which the supply air can flow, without supply air being able to escape through such holes.

The support elements are particularly preferably screwed to the shelf supports with thread-forming screws. In particular, the screws do not cut into the shelf supports. As a result, the surface of the shelf supports coated with zinc or a zinc compound is retained, so that the corrosion protection on the shelf supports is retained even in the areas in which the screws are screwed in.

The support elements advantageously consist of galvanized steel. In particular, the support elements are galvanized using a magnesium-zinc coating. Such a coating is for example under the trade name "Magnelis" commercially available. This coating further improves corrosion protection, particularly in the area of the threads formed in the shelf supports. All other parts of the shelf system made of steel, in particular the shelf supports, the support elements and the screws, are advantageously hot-dip galvanized.

In a particularly preferred embodiment of the invention, the support elements have a specially developed shape which allows the support elements to bear high loads on the shelves. In particular, it is provided that the support elements each consist of a multi-angled sheet. This sheet advantageously has an upper contact surface, through which the support element is screwed to the shelf supports, and a lower contact surface, through which the support element is also screwed to the shelf supports. The contact surfaces of the assembled support elements lie flat on the sides of the shelf supports. The support elements for the shelf supports are screwed to the shelf supports at two heights.

More preferably, the sheet metal, which forms the support element, has a flat support surface for a shelf between the upper contact surface and the lower contact surface. The shelf is preferably a board, especially a wooden board. Advantageously, the angled plate further has an inclined support surface which connects the support surface with the lower contact surface. As a result, the support surface is advantageously supported in the region of an outer edge of the support element. More preferably, the angled plate has an oblique connection surface which connects the support surface with the upper contact surface. The inclined connecting surface rises obliquely from the flat contact surface to the upper contact surface. Above the upper contact surface is preferably a bend to keep a shelf placed on the respective support element from the shelf support. In the area of the fold, the support element is in turn angled several times. The fold works effectively prevent tilting of the shelves when loading the shelf system. This protects the shelf supports, the support elements and the shelves from damage which could result in tilted shelves due to a collision with the shelf system. A less frequent occurrence of damage minimizes production interruptions and lowers costs. The fold is designed and arranged in such a way that every common shelf, in particular with a thickness in the range from 10 mm to 60 mm, is at least partially at the level of the respective fold when loading. Even screw heads of the screws, by means of which the shelf supports are screwed tight in the area of the upper contact surface, are protected against contact with the shelf bases, in particular also when the shelf bases are placed on the support elements, thanks to the bends.

Figure 1 shows an inventive device for storing objects under defined temperature and humidity conditions, in particular for hardening objects made of concrete. The device has a shelf system 1 and an air conditioning system 2. Parts of the climate system 2 are also isolated in Figure 2 shown. The line of sight in Figure 2 is identical to the line of sight in Figure 1 . The shelf system 1 has in an area provided for the storage of the objects behind two rows, each with twenty-two supports, ten rows, each with twenty-two shelf supports, which in Figure 1 are summarized with the reference number 3. The shelf supports 3 serve to support a plurality of shelves, which are not shown in the drawings for reasons of clarity. There are more in the side margins of the facility Supports the shelf system provided, which, however, like the supports 3 in the front two rows, do not support shelves. On the shelf supports or supports in the edge areas of the shelf system 1 there are cross braces for stabilizing the shelf system 1 mentioned. In the head area of the shelf system 1, support elements for connecting the supports and shelf supports 3 are transverse to the rows in which the supports and shelf supports 3 are arranged provided and in Figure 1 designated by the reference numeral 4.

In the embodiment according to Figure 1 a corridor is arranged on both end faces of the rows of shelves, from which at least one trolley with shelves can enter the desired row either for loading the shelves or for removing the shelves. Loading one aisle and removing the shelves from the aisle on the opposite end of the shelf system 1 results in a time advantage when loading. In an embodiment of the invention which is alternative to the embodiment shown, on the other hand, a passage is provided on only one end face of the shelf system 1, from which the shelves are fed for loading and through which the shelves with the hardened objects leave the shelf system 1 again. This results in a smaller footprint of the shelf system 1 and results in cost advantages for the shelf system 1.

The air conditioning system 2 has an air conditioning unit 5, which sucks in air through a return pipe system 6 and provides it with a desired temperature and a desired humidity in a supply pipe system 7. The return pipe system 6 has a return collecting duct 8. The feed pipe system 7 has a feed manifold 9. The collecting channels 8 and 9 extend in the head region of the shelf system 1 along the first two rows with the supports 3 of the shelf system 1. On the return collecting channel 8 there are numerous return collecting channel connections 10 provided, by means of which the carrier elements 4 are connected to the return manifold 8. A flow distribution pipe 11 is arranged parallel to each support element 4 and connected to the flow collection channel 9. Each flow distribution pipe 11 has five or six flow distribution pipe connections 12, by means of which the flow distribution pipes 11 are connected overall to every second shelf support 3 and to every second support 3 in the second row. The flow distribution pipe connections 12 are arranged offset to one another in such a way that in every row of the rack system 1 with rack supports 3 every second rack support 3 and transversely to the rows along the respective flow distribution pipe 11 also every second rack support 3 is connected to the flow pipe system 7.

In the Figure 3 , 4th and 5 parts of the device are shown enlarged from different perspectives. In Figure 3 the direction of view agrees with the direction of view of the Figure 1 and 2nd match. In Figure 4 is the direction of view towards the Figure 1 to 3 turned by 90 degrees. In Figure 5 is the direction of view towards the Figure 1 to 3 rotated by 180 °. For the individual designation of the supports and shelf supports 3 visible in the figures, the reference number is followed by a number separated by a point in the row in which the respective support or shelf support 3 is arranged, and a number in the respective row separated by a further point. Figure 3 shows with this designation a section with the supports 3.01.09, 3.01.10, 3.01.11, 3.02.09, 3.02.10 and 3.02.11. A number is added to the carrier elements 4, the return manifold connections 10 and flow distribution pipes 11 for individual designation separated by a point, which corresponds to the last part of the number of the respectively assigned support or shelf support 3. The flow distribution pipe connections 12 are individually identified according to the supports 3. The same reference numerals designate the same parts in all 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, support 3.02.11 is through the supply manifold connection 12.02.11 connected to the flow distribution pipe 11.11. The supports 3.02.09 and 3.02.11 are therefore parts of the supply pipe system 7 of the air conditioning system 2. The support 3.02.10 arranged between the supports 3.02.09 and 3.02.11, however, is not connected to the supply manifold 9 and is therefore not part of the supply pipe system 7 .

The carrier elements 4 are all parts of the return pipe system 6 and are connected to the return collecting duct 8 via the return collecting duct connections 10. The carrier elements 4 are C-profiles, which are closed by means of cover elements 13. Three cover elements 13 are in Figure 3 individually designated with the reference numerals 13.09, 13.10 and 13.11. The support elements 4 each have an exhaust air opening in the area of intersection with the supports 3 or shelf supports 3, which are not part of the feed pipe system 7, one in each row and from row to row in the area of every second shelf support 3, in particular in a checkerboard pattern Exhaust air opening is provided. At the ends of the carrier elements 4, edge exhaust openings are realized by means of first end caps 14, in particular first end caps 14.09, 14.10 and 14.11.

Figure 4 shows a section of the device according to the invention, which part of the in Figure 3 shows the section shown from a different perspective again. In particular are also in Figure 4 upper sections of columns 3.01.09, 3.01.10, 3.02.09 and 3.02.10 are shown. In addition, the in Figure 4 shown section of upper sections of columns 3.01.07, 3.01.08, 3.02.07 and 3.02.08. The first end caps 14.07 and 14.08 are also open and each have the function of an edge exhaust opening. No exhaust air openings are arranged in the area of the supports 3 of the second row.

At least the supports 3, which are part of the feed pipe system 7, that is to say in particular the supports 3.02.07 and 3.02.09, each have a cover element 15 which is individually connected to the support 3.02.07 with 15.02.07 and is individually identified on the support 3.02.09 with the reference number 15.02.09.

Figure 5 shows a section 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 can flow from the flow distribution pipe 11.11 into the cavity formed by the shelf support 3.12.11 and covered by the cover element 15.12.11. As an alternative to the exemplary embodiment shown, all shelf supports 3.12 which are arranged at the edge of the shelf system 2 are also part of the feed pipe system 7 and conduct supply air into the area of the shelf system 1 near the floor. 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. The second end cap 16.11 is closed in the area of the shelf support 3.12.11, which is part of the supply pipe system 7. The second end caps 16.10 and 16.12, which are arranged in the area of the shelf supports 3.12.10 and 3.12.12, are open and each form an edge exhaust opening. As an alternative to the exemplary embodiment shown, all end caps 16 are open and each form an edge exhaust opening. As a rule, that means, for example, with the exception of the first two rows according to the Figure 3 and 4th , a shelf support 3 is always alternately arranged at the same time a downward pipeline of the feed pipe system 7 or adjacent to an exhaust air opening of the return pipe system 6.

Figure 6 shows a section of the shelf system 1 in the foot area with the shelf supports 3.12.16, 3.12.17, 3.12.18 and 3.12.19. The line of sight is the same as that of Figure 5 . The shelf supports 3 are not yet concreted into a base plate. Therefore in Figure 6 a steel substructure 17 visible, which consists of several parallel to each other and transverse to the alignment of the rows of support rails 18, of which the in Figure 6 visible support rails 18 with the reference numerals 18.16, 18.17, 18.18 and 18.19 are designated. Between the rows of racks, rails 19 are preferably arranged in pairs on the mounting rails 18 and transversely to the orientation of the mounting rails 18. The rails 19 are fastened to the mounting rails 18 by means of clamps. Trolleys for loading the shelf system 1 can be moved on the rails 19.

The shelf supports 3.12.17 and 3.12.19 are further developed by means of the cover elements 15.12.17 and 15.12.19 into tubes in which the supply air flows downwards and through supply air openings 20, which are individually identified here with the reference numbers 20.12.17 and 20.12.19 , can flow out. The supply air openings 20 can be set, the throughput of supply air through the supply air openings 20 being set. The shelf supports 3 are fastened to the steel substructure 17 by means of angle plates and screw connections. After the construction and alignment of the shelf system 1, the substructure 17 is cast into a base plate and is therefore no longer visible in the operation of the shelf system 1. By pouring the base plate, the entire steel substructure 17 and the rails 19 are grouted with concrete. The base plate thus produced counteracts bending of the rails 19, even if there is a trolley for loading the shelf system 1 on these rails 19.

The car is in particular a loading system and can have a weight of several tons. The trolley preferably also carries all the shelves that are to be arranged one above the other in a section of the shelf system 1. All of these shelves are simultaneously placed on the support elements 21 provided for this purpose. After the objects have hardened, all of the shelves arranged one above the other are lifted together again and driven with the trolley to one end of the respective aisle. After this, shelves with objects to be hardened are preferably moved again by means of the trolley into the area with the now free-standing support elements 21 and placed on these shelves. This is preferably done fully automatically.

Figure 7 shows a section similar to the section of Figure 6 , however, support 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, on the shelf support 3.12.22 center shelves which are to be placed on the support elements 21 when retracting.

A large number of support elements 21 are shown in the sectional view of the device according to the invention with the shelf system 1 and the air conditioning system 2 Figure 8 to recognize. A section marked "S" from the representation of Figure 8 is in Figure 9 shown enlarged.

In Figure 10 is a section labeled "R" with two structurally identical support elements 21, of which only a first support element with the reference symbol 21 and the second support element with the reference symbol 21 'is shown here to distinguish them, enlarged again. Each support element 21, 21 'is a multi-angled and galvanized steel sheet which, from bottom to top, adjoining one another is a not further designated slope, a lower contact surface 23 bordering the slope, an inclined support surface 24, a flat support surface 25, one has inclined connecting surface 26, an upper contact surface 27 and a bevel 28. The bevel 28 has an inclined surface which is aligned parallel to the inclined support surface 24. The bevel 28 then 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 flat contact surface 25.

All features mentioned in the above description and in the claims can be combined in any selection with the features of the independent claim. The disclosure of the invention is thus not limited to that described and / or claimed Characteristic combinations are limited, rather all combinations of features which are meaningful in the context of the invention are to be regarded as disclosed.
