Description

The invention relates to a buoyancy protection for a container set up in the ground, in particular a liquefied gas container, which buoyancy protection has a container support and connected to it at least on the long side with respect to a container to be accommodated on the container support, each anchor plate with respect to the container support from a non-use position to a use position, in which protrudes such an anchor plate laterally partially or with its entire surface over the width of the base surface of the container projected onto a horizontal surface, is translationally adjustable. The invention further relates to a container to be set up in an earth-covered manner, in particular a liquid gas container with a buoyancy protection connected to it.

Containers, particularly those that can also be addressed as tanks, can be installed above or below ground. When such a container is installed underground, it is a matter of containers which are to be erected or set up in the ground. Such containers are known for example as liquid gas containers or fuel oil containers. When installing such a tank in the ground, measures must be taken depending on the hydrogeological situation on site so that such a tank installed in the ground does not float when the groundwater level rises, especially if it is partially emptied or emptied. Anchor plates are used as buoyancy protection, which are arranged on the longitudinal sides of a base plate carrying the container and, in order to effect the buoyancy protection, project in whole or in part above the base surface of the container projected onto a horizontal surface. The effect is that the anchor plates are located in an area that can be covered with soil or other bulk material up to the surface of the soil. In the case of a container installed in the ground, the anchor plates thus serve as the one surrounding the container Soil engaging barbs that effectively prevent a floating movement. The surface of the anchor plates protruding beyond the projected base area of the container is adapted to the volume of the container and thus to its possible buoyancy force or is dimensioned accordingly, so that it effectively prevents floating due to the earth covering.

In order to reduce the space requirement of such a container during transport, in EP 1 433 722 B1 have been proposed to connect the anchor plates to a base plate in an articulated manner. These anchor plates can be pivoted from their erected non-use position, in which they do not protrude over the projected base area of the container, into a use position, in which they protrude with the desired area over the projected base area of the container by a pivoting movement. The container, which in this prior art is designed as a liquid gas container, is connected to a base plate by means of saddle feet, as a result of which a unit consisting of container and buoyancy protection is created.

When installing such a container in a building pit, it must be ensured that the anchor plates are folded out of their non-use position into their use position before the container is inserted. When inserting such a container with its buoyancy protection in the position of use into a construction pit, special attention must be paid to this previously known buoyancy protection that the anchor plates are actually in their fully unfolded position even with the container inserted in a construction pit and not because of a too narrow position The excavation pit is fully or partially folded up again. Otherwise, the contact area provided by the anchor plates may not be sufficient for soil or other filler material to be applied to effectively prevent floating. The base of such an excavation pit is typically not secured, so that it is not possible to access people to remove stones that have been left on the base, for example, and which result in the anchor plates being readjusted. In addition, caution is required when unfolding the anchor plates so that they do not swing down in an uncontrolled manner.

Out US 6,345,933 B1 A further buoyancy protection for a container to be set up in an earth-covered manner is known. This previously known safety device has a base frame on which the container rests. The base frame comprises two longitudinal profiles spaced apart from each other, between which the container engages with its apex on the underside. The base frame also includes transverse square profiles. Second profiles are slipped onto the free ends of these square profiles and are translationally adjustable relative to the frame-side profiles. An anchor plate is connected to each side of the frame at these second profiles, which are guided through the frame-side profiles. In this way, the anchor plates can be adjusted in translation relative to the base frame. The anchor plates stand up on the floor when the buoyancy protection is switched off. In their non-use position, these are located within the projected base area of the container. For installation in the ground, the anchor plates are pulled outwards into their position of use. To do this, the container must be raised. The container itself is clamped to the anchor plates by means of straps. A disadvantage of this known buoyancy protection is that the frame of the buoyancy protection must be designed to be very stable so that it is not bent due to the belt tension. In addition, with this known buoyancy protection it is necessary to fix the extended anchor plates with their second profiles guided on the frame-side profiles in the extended position with bolts. It is also considered disadvantageous that when the anchor plates are pulled out of their non-use position for transporting the container into their use position, the tensioning straps have to be released and then re-tensioned. In addition, it is not possible to move the anchor plates from their non-use position to their use position when the container is placed on a surface.

Based on this discussed state of the invention, the invention is therefore based on the object of proposing a buoyancy safety device which can not only be handled easily, but which can also be used to ensure that the anchor plates move translationally from their non-use position into their use position adjusted, too have been adjusted sufficiently to ensure the desired buoyancy protection. Furthermore, it would be desirable if the buoyancy protection could be made as light as possible.

This object is achieved according to the invention by a buoyancy device of the type mentioned at the outset, in which the buoyancy device as a container support has at least two support blocks spaced apart in the longitudinal direction of the container, which are equipped with connecting means for bracing a container located on the support blocks and on the underside at least via a guide channel and have a base-side support, and that each anchor plate carries at least two rails projecting in the transverse direction to the other anchor plate, one of which engages in a guide channel of a support bracket.

This buoyancy safety device has at least two support blocks spaced apart from one another in the longitudinal direction of the container to be accommodated. Taking advantage of the stability of the container, it is sufficient in many cases to provide only two support brackets even in the case of a longer container. The support brackets are equipped with connection means for bracing a container on them. With this buoyancy protection, the container is thus connected to the support stands. As a result, the anchor plate guides do not need to be so stable that they can withstand the clamping force required to hold the container securely on the support blocks without deformation. This configuration also allows the formation of a buoyancy safety device without the connection means provided for holding the container on the trestles. These can be straps that tension the container to be held or straps, typically stainless steel straps. Those made of fabric are used as belts. When using belts, it is not absolutely necessary to arrange plastic intermediate layers between the belt and the container, which is useful if steel strips are provided to protect the outer surface of the container. The trestles can also be permanently connected to the container as part of the buoyancy protection, for example welded to the container. Of particular advantage with this type of container attachment is that Anchor plates can be adjusted translationally with respect to the support brackets without this having any influence on the fastening of the container to the buoyancy protection. For the adjustability of the anchor plates, the support blocks have at least one guide channel on the underside. The anchor plates themselves have at least two rails projecting in the transverse direction to their longitudinal extension to the other anchor plate. The rails of the anchor plates are arranged relative to one another such that one rail of each anchor plate engages in a guide channel of a support bracket. It is provided that the rails engage in such a guide channel in a side-by-side arrangement in their engagement position. As a result, the depth of engagement of the two rails held in a guide channel of a support bracket is independent of the respectively adjacent rail. In particular, this allows the rails to be designed to be particularly long, so that the pull-out amount of the anchor plates is correspondingly large in accordance with the length of the rails. In the non-use position, the rails of one anchor plate can in principle extend into the area of the opposite anchor plate if a particularly large pull-out amount is desired. This arrangement of the two rails assigned to a support bracket makes it possible for the anchor plates, even if they are designed to be relatively wide, to be able to be placed overall outside the outline of the container projected into the plane of the anchor plates. The same can also be achieved if the two rails of the two opposite anchor plates are arranged one above the other.

It is possible to design that each rail engages in a common guide channel of a support bracket. According to another embodiment, it is provided that each rail engages in its own guide channel as part of a support bracket and is guided therein. Another advantage of the concept of providing the support blocks is that they are equipped on the underside with a base-side support, for example feet. These are typically connected to such a guide channel. Through these feet, the buoyancy protection can be placed on a surface, typically a level surface, without the anchor plates being in contact with the ground. These can then even when the buoyancy protection system is installed on the floor, they can be easily moved from their non-use position into their use position.

The maximum amount of adjustment that an anchor plate can be translationally adjusted out of its non-use position can be easily limited by a corresponding stop. This gives a person pulling out an anchor plate a haptic and also acoustic feedback that the anchor plate is in its intended extended position as soon as the stop arrangement is reached. The extended position can be secured by a detent, for example by means of a detent bolt or by a securing bolt which is pushed through the guide channel and the at least one rail guided therein when the pull-out position is reached.

According to one exemplary embodiment, it is provided that the rails of the anchor plates pass through the respective guide channel of a support bracket and therefore these rails protrude from the guide channel with a section at the end opposite the respective anchor plate. The length of the section protruding from the guide channel in the non-use position corresponds to the length of the envisaged adjustment amount or is slightly longer than this. With such a design of the buoyancy protection, the stop can be brought about by a bolt inserted into the rail, which, when the anchor plate with its rails is pulled out of the guide channels of the support blocks, acts against the end wall thereof. Such a stop can also be provided by a rail having a flange-like head. This is possible, for example, by inserting a head insert into the rail which is open at this end, which head insert has a flange which projects on at least one side. The head insert can be connected to the rail by a weld or by a fastener. It goes without saying that, with such a configuration, the head does not have to project over the entire length of the rail. Then the rails guided through the guide channel or channels of a support block opposite anchor plates can be arranged at a correspondingly smaller distance from each other.

The guide channel on the underside of such a support bracket, if the support bracket itself has a base plate, can be provided by a U-profile, which is then closed on the upper side by the base plate of the support bracket. The guide channel can also be provided by a tube, for example a square tube. If a separate guide channel is provided for each rail, it is advisable to arrange two pipes on the underside of the support bracket. These are typically offset from one another. It is also possible to use a cylindrical tube. The rail of an anchor plate guided therein has a geometry that is complementary to the inner cross-sectional geometry of the guide channel. A certain amount of play between the lateral surface of the rail and the inner lateral surface of the guide channel will be provided in order to achieve easy adjustability. This is also without consequences for the handling of the buoyancy protection, since the anchor plate connected to two such rails, due to the resulting one-sided weight loading, causes the rails associated with an anchor plate to tilt to a certain extent in the guide channels. Additional safeguards are therefore generally not required so that such an anchor plate remains in its non-use position or in its use position. To adjust such an anchor plate, one will raise it slightly to remove the tilting arrangement and then adjust it translationally with respect to the guide channel or channels. Nevertheless, it is provided in one embodiment that the extended position of the anchor plates is fixed, for example by a locking bolt. This is mounted in the wall of the guide channel and, when the respective anchor plate is in its extended position of use, jumps into a corresponding locking receptacle of the rail guided into the guide channel. The use of ball catches is also possible. Fixing of the extended anchor plates is also possible by means of a securing element to be set manually, for example a split pin, a screw or the like, this securing element locking the rail guided in the guide channel with respect to the guide channel.

According to one embodiment, the support brackets themselves have a trough-like depression. The radius of curvature of the trough-like depression is adapted to the lateral surface of the container to be placed on it. The trough-like depression is preferably provided by a profiled component which has two side cheeks which extend beyond the longitudinal extent of the depression. The side wall sections which extend beyond the longitudinal extent of the trough-like depression are used in a preferred exemplary embodiment in order to provide the means for fixing the container thereon. This can be, for example, bores or openings for fixing a belt fastening bolt. The tensioning forces introduced therein, for example via a fastening bolt penetrating the two side wall sections, are introduced into the plane of the side wall sections, consequently in a direction in which they have their greatest stability anyway due to their planar extent. Depending on the design of such a support bracket, such a fastening bolt can be fixed, for example welded, in the bores of the side wall sections. Detachable configurations are also possible in which such a belt fastening bolt is inserted into the side wall section bores and can also be detached from these if necessary.

The provision of at least two support blocks spaced apart from one another in the longitudinal direction of the container as the container support and the bracing of the container on or with the support blocks permits a modular design of the buoyancy protection. The distance between the trestles is adapted to the length of the container to be set up in the ground. In the case of a shorter container, the distance between the support blocks is smaller; correspondingly longer for a longer container. The spacing of the support brackets in this buoyancy protection is determined by the distance of the rails on the anchor plate side, which are guided in the guide channels of the support brackets. In the case of a container that is shorter in terms of its length, the anchor plates are correspondingly shorter, as is the distance between the rails guided in the support blocks. In the case of a longer container, the anchor plates are correspondingly longer and thus also the distance between the rails guided in the trestles. In this respect, one and the same support brackets can be used to form buoyancy safeguards of different lengths, to which anchor plates of different lengths are connected or are connected, depending on the length of the container to be placed thereon. It is also possible to design the anchor plates themselves in two parts, for example, so that the length adjustment of the buoyancy protection is carried out by varying one of the two anchor plate modules. Depending on the length of the desired buoyancy protection, a second such module with the required remaining length is connected to one and the same anchor plate support bracket basic module in such a configuration. This is possible in a simple manner by connecting the anchor plates of the two anchor plate modules on the face side. Of course, due to the modularity described, buoyancy safeguards can also be created that consist of three or more modules.

Another embodiment provides that an anchor plate has two anchor plate rails, one of the two rails being guided telescopically in the other rail. The length of such an anchor plate can thus be set up by moving the two anchor plate rails. A rail engaging in a guide channel of a support bracket is connected to each anchor plate rail. In such a configuration, it is possible to adapt the spacing of the support brackets as a function of the length of the container to be placed thereon. With this concept, the setup is typically provided in a stepless manner.

The anchor plates themselves can have handles to make it easier to pull them out of their non-use position into their use position. Typically, each anchor plate, if handles are desired, has two handles arranged at a certain distance from one another, the distance between the handles being such that one person can easily grasp both handles on the same side. The handles themselves can be designed as handles that protrude from the outer longitudinal sides. If the handles should not protrude from the outside of the anchor plates in relation to the width of the buoyancy protection, these can also be arranged at the top, typically protruding in the area of their edge termination. It is also possible to insert the handles into the anchor plates as handle openings. One handle or the pair of handles is located in the middle between the typically two rails. This ensures that the rails guided in the guide channels of the support blocks do not tilt when they are pulled out.

A liquid gas container 1 is designed as a horizontal cylindrical container and has a dome 2 through which the supply and discharge lines (not shown) are guided. The liquid gas container 1 is placed on a buoyancy safety device 3 and braced with it by means of belts 4, 4.1. The buoyancy protection 3 has, as container receptacle, two support blocks 5, 5.1 spaced apart from one another in the longitudinal extent of the container 1. The support brackets 5, 5.1 form the sub-support for the liquid gas container 1. Connected to the support brackets 5, 5.1, following the longitudinal extension of the liquid gas container 1, there is an anchor plate 6, 6.1 on each side. The anchor plates 6, 6.1 are profiled sheet metal parts. The profiling of the anchor plates 6, 6.1 serves to stiffen them. In the illustrated embodiment, these are profiled in the manner of a "W". The anchor plates can also be designed with a U-shaped profile, as can other profiles. The anchor plates 6, 6.1 are connected to the bearing blocks 5, 5.1 by means of rails 7, 7.1. In Figure 1 the rails assigned to the anchor plate 6.1 are covered due to the liquid gas container 1. These are in the Figure 2 , which shows the buoyancy protection 3 without the liquid gas container 1 located thereon, visible. The rails mentioned are identified by reference numbers 7.2, 7.3. Figure 1 shows the anchor plates 6, 6.1 of the buoyancy protection 3 in its use position. In this, the anchor plates 6, 6.1 protrude beyond the width of the base surface of the liquid gas container 1 projected onto a horizontal surface.

Below is with reference to the Figures 3 to 6 the support bracket 5 and the connection of the rail 7 of the anchor plate 6 explained in more detail. The support bracket 5.1 is constructed identically. Likewise, the further rails 7.1, 7.2 and 7.3 are guided on or in the respective support bracket 5 or 5.1 in the same way. The following explanations therefore apply equally to the support bracket 5.1. The support bracket 5 has a U-shaped profiled base element 8, which has a base plate 9 and two side walls 10, 10.1. The opening of the base element 8 points upwards in the vertical direction. A trough-shaped depression 11 is made in the side cheeks 10, 10.1. The radius of the recess 11 corresponds to the radius of the liquid gas container 1 in the region of its lower apex. The base element 8 is closed on the upper side in the region of the recess 11 by a striking plate 12. The side cheeks 10, 10.1 extend beyond the longitudinal extent of the depression 11. In the sections protruding beyond the recess 11, the side cheeks 10, 10.1 are designed with an incline in the direction of the base plate 9 (see also Figure 3 ). An opening 13, 13.1, which is arranged in alignment with one another on both sides, is introduced into these sections on both sides for inserting a belt fastening bolt. The belts 4, 4.1 are connected to such a belt fastening bolt which extends through the openings 13, 13.1 (see FIG. Figure 1 ).

The tension of the belts 4, 4.1 is thus introduced into the side walls 10, 10.1 in the direction of their plane. In other words: the tension force acts on the side walls 10, 10.1 as a pulling force in the direction of their flat extension. Such a belt connection is expedient since the belts 4, 4.1 can also be connected to these side cheeks and thus to the support bracket 5 with a high tension force, without the side cheeks 10, 10.1 needing any special reinforcement for this purpose. On the base plate 9 of the base element 8 are, as from Figure 3 can be seen, connected on the underside two square hollow profiles 14, 14.1 lying side by side in one plane. The square hollow profiles 14, 14.1 each provide a guide channel for the rail 7 of the anchor plate 6 or the rail 7.2 of the anchor plate 6.1 with their interior. The side view of the support bracket 5 of the Figure 4 shows the side-by-side arrangement of the square hollow profiles 14, 14.1, without the rails 7, 7.2 engaging therein. The rails 7, 7.2 of the anchor plates 6, 6.1, each engaging in a guide channel of the support bracket 5, are offset with respect to the length of the respective anchor plate 6, 6.1, so that the ends of the anchor plates 6, 6.1 are aligned with one another. The offset corresponds to the offset of the guide channels provided by the square hollow profiles 14, 14.1 in order to be able to implement the desired side-by-side arrangement of the guide channels. In the front view of the Figure 5 shown position of the anchor plates 6, 6.1, which corresponds to the position of use, the extension movement of the rails 7, 7.2 relative to the square profiles 14, 14.1 is limited by a stop 15. The in Figure 5 recognizable stop 15 designed as a bolt is associated with the rail 7 and acts against the end face 16 of the square profile 14 which widens the guide channel for the rail 7 and points away from the anchor plate 6.

Is entered in the Figure 5 also schematically shows the width of the base area of the liquid gas container 1, indicated by reference number 17.

It can be clearly seen that the anchor plates 6, 6.1 project in their use position overall over the projected width 17 of the base area of the liquid gas container 1. Thus, the entire surface of the anchor plates 6, 6.1 is effective for securing against buoyancy.

Feet 18 are attached to the square profiles 14, 14.1, via which the support bracket 5 stands on the floor side. The height of the feet 18 is dimensioned such that the anchor plates 6, 6.1 have no ground contact. This allows simple adjustment of the anchor plates 6, 6.1 from their non-use position to their use position with the buoyancy protection system installed at the bottom.

The front view of the Figure 5 also makes it clear that the rails 7, 7.2 engaging in the guide channels of the square profiles 14, 14.1 can tilt due to the one-sided weight of the respective anchor plate 6, or 6.1 within the respective guide channel. For this purpose, a certain play is provided between the rails 7, 7.2 and the inner wall of the guide channels. Such tilting can be consciously accepted, since it fixes the position of the anchor plates 6, 6.1 to a certain extent. In order to adjust the anchor plates 6 and 6.1, these are raised somewhat in order to cancel the tilting arrangement, in order then to be easily adjusted in translation relative to the support brackets 5, 5.1.

While in the Figures 1 , 2nd and 5 the buoyancy lock 3 with its anchor plates 6, 6.1 is shown in its position of use and thus in the installation position in the ground, is in the Figures 6 and 7 the buoyancy protection 3 with its anchor plates 6, 6.1 shown in the non-use position. In this position, the anchor plates 6, 6.1 with their rails 7, 7.1, 7.2, 7.3 are pushed in relative to the support brackets 5, 5.1. This is the typical transport position of the buoyancy lock 3 or the arrangement comprising the liquid gas container 1 and the buoyancy lock 3. The anchor plates 6, 6.1 are then within the projected width of the base area of the liquid gas container 1. Before installing the liquid gas container 1 with its buoyancy lock 3 the anchor plates 6, 6.1 also pulled out in relation to the support brackets 5, 5.1 into their position of use, such as through the block arrows of the Figure 6 indicated. For this purpose, the anchor plates 6, 6.1 have handles 19, 19.1, each anchor plate 16, 16.1 each carrying two spaced handles 19 and 19.1 on their narrow side pointing away from the support blocks 5, 5.1 (see also Figures 1 and 2nd ).

In the anchor plates 6, 6.1 shown in the figures, these are composed of two anchor plate pieces. The anchor plates can of course also be made from a continuous piece of anchor plate.

The invention has been described using exemplary embodiments. Without departing from the scope of the applicable claims, there are numerous other possibilities for a person skilled in the art to implement the claimed buoyancy protection without this having to be explained in detail in the context of these statements.
