Existing hazardous goods containers face challenges with limited access openings, requiring significant space for filling and unloading, especially for larger containers, and often necessitate clear space in front of the container due to pivoting doors.
A hazardous goods container with sliding gates that move along the opening, covering at least 80% of the container height, allowing effective filling and unloading, and featuring a stable frame structure with inner and outer frames, rollers, guide rails, and dampers for secure operation and fire resistance.
The solution provides a compact design with efficient loading and unloading capabilities, ensuring a stable structure and fire resistance of at least 60 minutes, with secure sealing and automatic closure in the event of a fire.
Description
[0001] The present invention relates to a hazardous goods container, in particular as a fire protection container, with a collecting tray on the bottom, a roof and side walls connecting the collecting tray and the roof, which are fixed to a frame.
[0002] For the storage of hazardous substances, it is known from DE 20 2017 101 249 U1 to equip a hazardous goods container with a base sump, side walls, and a roof, with panels lined with sheet metal on both sides held between an inner and outer frame. This allows the hazardous goods container to have a stable structure that has a fire resistance duration of at least 90 minutes in the event of a fire. For filling the fire protection container, a pivoting door is provided on one side wall. This provides access to the interior of the hazardous goods container, which can be designed either as a pure storage shelf or for personnel to walk through. Particularly with larger hazardous goods containers, the problem arises that the access opening for filling the hazardous goods container is relatively small, making storing containers difficult.Another disadvantage is that with large pivoting doors, the space in front of the hazardous goods container must be kept clear to avoid blocking the door. FR 3 018 788 also shows a similar hazardous goods container.
[0003] WO 92 / 14901 discloses a transportable large container with a fire-resistant sliding door consisting of two sliding panels. The suspended sliding panels are movable via two guide rails attached to the ceiling of the container.
[0004] In addition, transport containers are known in which hanging sliding doors are used, as disclosed in JP 2001-48284.
[0005] It is therefore an object of the present invention to provide a dangerous goods container which requires little space and can also be filled effectively.
[0006] This problem is solved with a dangerous goods container having the features of claim 1.
[0007] In the hazardous goods container according to the invention, at least one sliding gate is movably mounted on at least one side for opening and closing an opening on the hazardous goods container. This reduces the space required when opening the hazardous goods container, as the at least one sliding gate is only moved along the opening and thus does not protrude from the hazardous goods container due to a pivoting movement. Especially with larger hazardous goods containers, a large access opening can be opened by the sliding gate, allowing the hazardous goods container to be filled or unloaded effectively with containers and drums.
[0008] Preferably, the at least one sliding gate extends over at least 80% of the height of the dangerous goods container, so that filling and unloading of containers can take place essentially over almost the entire height in the horizontal direction along the access opening.
[0009] For particularly effective loading and unloading of the hazardous goods container, two sliding gates can be arranged at different levels on one side, so that each sliding gate covers an access opening on the container. The two sliding gates can preferably cover at least 80% of the area of the side wall, so that each sliding gate can open up almost half of the area of the side wall for filling and unloading. The side wall with the two sliding gates is preferably arranged on one long side of the hazardous goods container. Optionally, sliding gates can also be provided on both long sides, so that the hazardous goods container can be filled and unloaded from opposite sides.
[0010] To ensure a stable structure, the hazardous goods container preferably has a frame with an inner frame within the side walls and roof and an outer frame outside the side walls and roof. The inner frame can be essentially cuboid-shaped and comprise several posts that support an upper frame below the roof. The posts can be fixed or supported on the collecting tray, which is preferably made of bent sheet steel. The side walls and roof can then be fixed to the inner frame, with panels preferably being used for this purpose, which have a core made of fire-retardant material and are covered on both sides with a sheet metal. To ensure a stable structure, the frame also comprises an outer frame, which is arranged outside the side walls and roof and also has posts and a frame in the area of the roof to securely fix the roof and side walls.
[0011] In one embodiment according to the invention, the at least one sliding gate is supported by rollers and guided along a guide rail on an upper side. The weight of the sliding gate is then transferred by the rollers, so that only lateral support of the sliding gate is provided on the upper side, which is subject to greater load in the event of a fire. Preferably, the rollers are mounted on the sliding gate and can be moved along a guide rail that is supported on a floor section of the hazardous goods container.
[0012] To guide the at least one sliding gate in the upper region, a guide rail is provided, which is preferably fixed to an upper side of the sliding gate and can be moved along rotatable, but stationary guide rollers or sliding elements. Alternatively, the guide rail could also be fixed to the roof of the container, with rollers or sliding elements arranged on the upper side of the sliding gate. The guide rail is preferably U-shaped in cross-section and, when fixed to an upper side of the sliding gate, has upwardly projecting legs, between which sliding elements and / or guide rollers are arranged.
[0013] To ensure secure closing of the sliding gate, each sliding gate is pre-tensioned into a closed position by a spring element. Such a spring element has a weight that can be moved via a cable pull, for example, in a pocket on a side wall. This allows the sliding gate to close automatically from an open position in the event of a fire. Optionally, the sliding gate can also be moved in the opening or closing direction via a drive, particularly an electric drive.
[0014] To slow the speed of the sliding gate during a closing movement, at least one damper is provided according to the invention. A damper can be designed, for example, as a rotary damper connected to a pulley that is moved by the cable arranged between the weight and the sliding gate. Alternatively or additionally, another damper, for example a linear damper, can be arranged on the closing side of the hazardous goods container. This allows the heavy weight of the sliding gate to be safely slowed down.
[0015] For ease of handling, a magnet can be provided on the hazardous goods container, which can be used to fix a sliding gate in an open position. This magnet can, for example, be powered, so that in the event of an accident or emergency release, the magnetic forces are deactivated by switching off the power, and the sliding gate automatically moves into the closed position. The holding forces of the magnet are therefore preferably higher than the tensile forces exerted by the at least one spring element that preloads the sliding gate into the closed position.
[0016] The bottom of the collecting tray is preferably provided with at least one grating for the storage of containers, in particular drums, IBCs, KTCs, chemical and Euro pallets containing liquids, or other storage elements containing fluids. This allows the hazardous material to drain into the collecting tray, which is preferably made of bent sheet steel, in the event of a leak.
[0017] To configure the hazardous goods container as a fire-protection container, the upper edge of each sliding door is preferably arranged between two cover bars. The cover bars can comprise or be made of intumescent material. The overlap of the cover bars perpendicular to the direction of travel of the sliding door is preferably greater than 5 cm, for example, between 6 and 20 cm. This ensures secure closure at the upper edge of the sliding door in the event of a fire. Such cover bars can optionally also be provided on a vertical side wall on the closing side of the sliding door.
[0018] Preferably, the sliding gate has a strip-shaped projection on the side facing the opening direction, which, together with another strip-shaped projection, provides a seal. The additional strip-shaped projection can be arranged either on a fixed panel of a side wall or on another sliding gate. The strip-shaped projections can be hook-shaped and interlock, thus providing a reliable seal on the opening side of each sliding gate. An intumescent material can be provided on the strip-shaped projection, or the gates can be formed from this material to ensure secure closure in the event of a fire.
[0019] For reliable sealing of the hazardous goods container, a ventilation flap that closes automatically in hot conditions can also be provided. The ventilation flap can be pre-tensioned into the closed position by a spring, for example, and held in the open position by a retaining element made of a fusible material, such as plastic. Such a retaining element can be designed, for example, as a plastic screw, so that heat development or the escape of smoke gases can be prevented in the event of a fire.
[0020] In the event of a fire, the hazardous goods container according to the invention preferably has a service life of at least 60 minutes, in particular at least 90 minutes or 120 minutes according to EN 13501-2-2010 in accordance with REI-1-60 and REI-2-90, thus ensuring fire protection for a relatively long period of time. Preferably, the hazardous goods container simultaneously meets all three fire resistance classes according to EN 13501-2, namely REI-1-60, REI-2-90, and REI-2-120.
[0021] The invention will be explained in more detail below using an exemplary embodiment with reference to the accompanying drawings. Figure 1 is a perspective view of a dangerous goods container according to the invention; Figure 2 is a perspective view of an inner frame of the dangerous goods container of the Figure 1 ; Figure 3 a sectional view through the dangerous goods container of the Figure 1 ; Figure 4 a detailed view of the dangerous goods container of the Figure 1with the sliding gate open; Figure 5 shows a detailed view of the lower guide of the sliding gates; Figure 6 shows a detailed view of the upper guide of the sliding gates; Figure 7 shows a sectional view through the opening side of the two sliding gates; Figure 8 shows a sectional view through a closing side of a sliding gate; Figure 9 shows a view of a ventilation flap, and Figure 10 shows a detailed view of a weight for closing a sliding gate.
[0022] A hazardous goods container 1 comprises a bottom-side collecting trough arranged in the interior and an upper roof 2, with side walls 3 provided on one or more sides between the collecting trough and the roof 2. In the illustrated embodiment, the side walls 3 are arranged on three sides, while on a fourth side two sliding gates 6 and 7 are arranged, each covering an access opening to the interior of the hazardous goods container 1. Outside the hazardous goods container 1, an outer framework with vertical posts 5 is provided, which support a frame formed from profiles 4 on the roof 2. The side walls 3 are formed from panels having a core made of non-combustible or fire-retardant material, for example, corresponding to building material class A1, and metal sheets are provided on both sides of the core for covering.
[0023] In Figure 2an internal framework 11 of the hazardous goods container 1 is shown, which is provided within the side walls 3 and the roof 2. The internal framework 11 comprises vertical posts 14, which in the upper area support a frame formed from longitudinal profiles 12 and transverse profiles 13, wherein the longitudinal profiles 12 and the transverse profiles 13 can be made from C-shaped folded sheets that are connected to one another with rivets. In the lower area of the posts 14, a collecting tray 10 is arranged, which is made from a bent steel sheet, preferably with a sheet thickness between 3 mm and 8 mm, in particular 4 mm and 6 mm. On the side walls of the collecting tray 10, strips 16 are provided, on which gratings can be supported, on which the containers with hazardous substances are then placed.
[0024] In Figure 3The dangerous goods container 1 is shown in section, and only a part of the rear sliding gate 7 is visible. The sliding gate 7 can be moved in the lower area along a guide rail 20, which is supported on a floor section 15. The sliding gate 7 is framed in a U-shape in the lower area and arranged between two cover strips 17.
[0025] In the upper area, the sliding gate 7 is arranged between downwardly projecting cover strips 28, which cover an upper edge of the sliding gate 7. The vertical overlap by the cover strips 17 and 28 can, for example, be at least 5 cm, preferably between 8 cm and 30 cm. The cover strips 17 and 28 can comprise or be made of an intumescent material in order to be able to securely close gaps between the sliding gate 7 and the cover strips 17 and 28 in the event of a fire.
[0026] In Figure 4A closing side for the sliding gate 7 is shown in detail. It can be seen that, next to the guide rail 20 on the floor section 15, an upwardly projecting cover strip 17 is arranged, which terminates on the closing side at a vertical cover web 32, so that a pocket is formed for one end of the sliding gate 7. A linear damper 22 is provided within the pocket, which brakes the sliding gate 7 during a closing movement shortly before it reaches the closed position. Several linear dampers 22 can optionally be arranged distributed over the height. Furthermore, a locking mechanism 21 is located on one end side of the sliding gate 7, which can be engaged with a bolt on the sliding gate 7 in order to lock the sliding gate 7 in the closed position. A control panel for the locking mechanism 21 can be provided on the post 5.
[0027] In Figure 5A lower section of the two sliding gates 6 and 7 is shown, which can be moved via rollers 23 on two guide rails 20 arranged at different levels. Between the two guide rails 20 is an upwardly projecting cover strip 17, so that the rear sliding gate 7 is enclosed in a U-shape between the cover strip 17 and a side wall 24 of the collecting tray 10.
[0028] In Figure 6an upper region of the sliding gates 6 and 7 is shown. Each sliding gate 6 and 7 is enclosed between two downwardly projecting cover strips 28, wherein the overlap of the cover strips 28 in the vertical direction is preferably between 5 cm and 50 cm, in particular 20 cm to 40 cm. In the upper region, the sliding gates 6 and 7 are only guided laterally, while the weight loads are carried via the lower rollers 23 and the guide rail 20. Each sliding gate 6 and 7 has a guide rail 25 on the upper side, which is U-shaped in cross-section and has upwardly projecting legs. Arranged within the guide rail 25 are guide rollers 26 which are mounted so as to be rotatable about an axis 27. The guide rollers 26 are held on the roof 2 of the dangerous goods container 1.Optionally, the guide rail 25 can also be fixed to the roof 2 and serve to guide sliding elements or guide rollers that are attached to one of the sliding gates 6 or 7.
[0029] In Figure 7 The closing side of the two sliding gates 6 and 7 is shown, which must also be sealed in case of fire. Attached to each sliding gate 6 or 7 is a projection 30 which has a web 31 arranged in the direction of travel. The hook-shaped projection 30 thus formed can engage in the closed position, as shown in Figure 7 This allows a gap between the two sliding gates 6 and 7 to be sealed on the opening side. The projection 30, like the cover strips 17 and 28, can comprise or be formed from an intumescent material.
[0030] In Figure 8A section through the closing side of the sliding gate 7 is shown. The vertical closing side is also arranged between two cover webs 32 made of intumescent material, which foam under the influence of heat and can close corresponding gaps.
[0031] In Figure 9 A further detail of the hazardous goods container 1 is shown. It shows a ventilation flap 40, which is arranged in an open position to ventilate the interior of the hazardous goods container 1. The ventilation flap 40 is biased into a closed position by a spring (not shown). To prevent the ventilation flap 40 from closing, a retaining element 41 made of meltable material, for example, plastic, is provided. This retaining element releases the ventilation flap 40 under the influence of heat, allowing it to close under the force of the spring.
[0032] In Figure 10A post 5 of the outer framework is shown, on which a weight 50 is held so as to be movable in the vertical direction. The weight 50 is connected to a cable pull 51, which is connected on the opposite side to the sliding gate 6. When the sliding gate 6 is opened, the weight 50 is lifted, so that the cable pull 51 and the weight 50 act as a spring element that preloads the sliding gate 6 in the closing direction. The sliding gate 6 can be held in the open position by a magnet, which introduces holding forces on the opening side of the sliding gate 6 to prevent the sliding gate 6 from moving in the closing direction. The magnet can be designed to be switchable, so that in the event of an accident or fire, the sliding gate 6 closes automatically via the spring element. A corresponding preloading and holding mechanism can also be provided for the sliding gate 7.
[0033] To slow down the movement of the sliding gate 6 in the closing direction, the cable pull 51 can be provided with a rotary damper on a deflection pulley to prevent the heavy sliding gate 6 from striking the post 5. Additionally, one or more linear dampers 22 can be provided, as shown for the sliding gate 7. The sliding gates 6 and 7 can be constructed identically, but can only be opened in opposite directions.
[0034] In the illustrated embodiment, two sliding gates 6 and 7 are provided on one long side of the hazardous goods container 1. It is, of course, also possible to provide only a single sliding gate 6 or 7 and arrange fixed side walls in the remaining area. Furthermore, more than two sliding gates 6 or 7 can be arranged on one or more sides of the hazardous goods container 1. List of reference symbols
