Description

The invention relates to an arrangement of several shut-off devices for preventing the passage of land vehicles, in particular of trucks, each shut-off device having at least one Absperrpfahl.

The invention also relates to a method for producing an arrangement of a plurality of shut-off devices, wherein each shut-off device has at least one anchoring device, on each of which a fastening end of a shut-off pile is fixed or can be fixed.

In order to prevent the passage of land vehicles, usually shut-off devices are used, which are designed such that they can not be forcibly driven over at least for vehicles up to a certain size and at least up to a certain speed. Such shut-off devices are commonly used to protect buildings or people from the impact of vehicles. In order to ensure that the shut-off device forms sufficient resistance, massive bollards are often anchored very deep in the ground, for example by setting in concrete. However, such a type of anchoring is not possible or only with considerable effort, if in the ground already objects, such as electrical lines, water pipes, gas pipes or underground tanks, are present at shallow depth, which preclude a deep anchoring of Absperrpfählen. In such cases, so far remained only the possibility of relocating existing in the ground items, if at all possible, to a different location or to dispense with the installation of the bollards entirely.

Out WO 2007/091977 A1 is a system with multiple bollards known. The system includes a foundation made of reinforced concrete into which the bollards are cast. The installation of the system is very cumbersome and secondarily expensive. A similar system is off WO 2007/091978 A1 known.

It is therefore an object of the present invention to provide an arrangement of shut-off devices, which can also be used when only a small amount of vertical space in the ground is available and is easy to install.

The object is achieved by a shut-off device of the type mentioned above, which is characterized in that each shut-off device has an anchoring device designed as a finished part, in particular precast concrete part, to which a fastening end of the Absperrpfahles is set or is fixed and which is designed and intended to be so arranged, in particular invisible, under the earth's surface, that the Absperrpfahl protrudes vertically from the earth's surface, and that each adjacent shut-off devices are each firmly connected to each other with at least one connecting element.

It is a further object of the present invention to provide a method for producing an arrangement of a plurality of shut-off devices, in particular an arrangement according to the invention, which makes it possible to safely anchor several bollards in the ground quickly, if only a small vertical space in the ground is available.

1. a. Herstellen einer Grube im Erdreich,
2. b. Ablegen mehrerer Verankerungsvorrichtungen, insbesondere horizontal nebeneinander, in der Grube, wobei jede Verankerungsvorrichtung als Fertigteil, insbesondere als Betonfertigteil, ausgebildet ist,
3. c. Verbinden jeweils benachbarter Verankerungsvorrichtung mittels wenigstens eines Verbindungselements.
4. d. Absperrvorrichtungen horizontal nebeneinander auf dem Boden der Grube, wobei jede Absperrvorrichtung wenigstens einen Absperrpfahl aufweist, dadurch gekennzeichnet, dass jede Absperrvorrichtung eine als Fertigteil, insbesondere Betonfertigteil, ausgebildete Verankerungsvorrichtung aufweist, an der ein Befestigungsende des Absperrpfahles festgelegt ist oder festlegbar ist.

The further object is achieved by a method which is characterized by the following steps:

1. a. Making a pit in the ground,
2. b. Depositing a plurality of anchoring devices, in particular horizontally next to one another, in the pit, each anchoring device being designed as a finished part, in particular as a precast concrete part,
3. c. Connecting each adjacent anchoring device by means of at least one connecting element.
4. d. Shut-off devices horizontally next to each other on the bottom of the pit, each shut-off device having at least one Absperrpfahl, characterized in that each shut-off device as a finished part, in particular precast concrete element, formed anchoring device to which a fastening end of the Absperrpfahles is fixed or can be fixed.

The fact that the anchoring devices are designed as finished parts, in particular precast concrete parts, a quick and reliable installation is possible, in particular, it is avoided that in the installation on the curing of a curable material, such as concrete, has to be maintained. In this case, a finished part is understood in particular to mean a part which has been produced using a hardenable material, for example concrete. In particular, the finished part struts and / or support, in particular steel, include. The anchoring devices may advantageously comprise eyelets, in particular made of steel, which allow the anchoring devices to be attached to a crane in order to bring them into their final position in a previously excavated pit. Alternatively, it can also be advantageously provided that the anchoring devices have cast-anchor, can be screwed into the eyelets. This has the advantage that the eyelets after laying an anchoring device in the pit simply removed again. If the anchoring device is to be removed again, the eyelets can be screwed in again.

The invention has the very special advantage that even in such structural situations, one or more bollards can be safely installed against a run over with a land vehicle in which in the ground only a small vertical space, such as a space less than 1,000 mm, in particular less than 700 mm , or from about 600 mm, is available. This has an advantageous effect that the shut-off device according to the invention requires little vertical space and yet provides a secure protection against violent driving over with land vehicles.

For example, the shut-off device according to the invention can be readily designed so that it only takes a vertical space depth of 600 mm and yet the passage of a truck of 7.5 tons weight at a speed of 80 km / h or even, with correspondingly larger dimensions safely prevents the passage of a heavy goods vehicle weighing 40 tonnes at a travel speed of 50 km / h or 80 km / h.

In that regard, the inventive arrangement of shut-off devices can advantageously be installed above existing structures, such as pipes or tanks, without the structures would have to be damaged or moved to another location. In addition, the inventive arrangement of shut-off devices can advantageously be removed again with comparatively little effort. For example, it can be advantageously provided that the anchoring devices initially deposited loosely in the pit and then by means of connecting elements, preferably non-destructive and / or tool-free releasably connected to each other. The connecting elements may be formed, for example, as, in particular U-shaped, brackets which are merely inserted and which can be easily pulled out again when the connecting elements are to be removed again.

Easy removability and easy reinsertion of the arrangement or parts thereof according to the invention is particularly advantageous if, for example in a city area, it should be necessary to reach the underlying supply lines. A simple removability and easy replacement of parts of the arrangement is particularly advantageous if a stop one or more fasteners were damaged because they can be easily and quickly replaced without having to dismantle the entire assembly.

In addition, the arrangement of shut-off devices according to the invention has the further very particular advantage that it is modular, so that it is possible by joining several, in particular the same, modules to reliably secure even larger areas against the passage of a land vehicle. For this purpose, as will be described in detail below, it is advantageously provided that adjacent modules, after being placed in a pit in the ground, are firmly connected to one another, in particular in a form-fitting and / or materially bonded manner. It is not advantageous in view of the duration until completion of an installation, but also not excluded that the space between or above the anchoring devices is at least partially filled with concrete.

In an advantageous embodiment, the connecting element has a thread for producing a screw connection.

In a particularly advantageous embodiment, the connecting element is designed as a plug-in element that only needs to be plugged in for connecting adjacent anchoring devices. For example, the connecting element may be advantageously U-shaped and have two, in particular parallel, legs. For connecting adjacent anchoring devices, in this case, preferably from above, a leg is inserted into an opening of one of the anchoring devices, while the other leg is inserted into an opening of an adjacent anchoring device. The openings serve as coupling elements for coupling the connecting element. Such a design has the very special advantage that a, in particular positive or exclusively positive, connection between adjacent anchoring devices can be made quickly and reliably. In addition, there is the particular advantage that the connection can be solved easily, quickly and non-destructively again. This, for example, if the arrangement is to be removed again.

In particular, for connecting two adjacent anchoring devices equal size connecting elements can be used, when the anchoring devices are aligned parallel to each other. Alternatively, it is possible to use unequal fasteners when two anchoring devices are not aligned parallel to each other, for example, to achieve an arcuate arrangement of multiple anchoring devices.

The anchoring devices are preferably deposited as mutually separate finished parts horizontally next to each other in a pit. To achieve this, first a pit can be dug, which has a level, horizontal ground on which the Anchoring devices are stored. Subsequently, the overlying space can be filled up to the earth's surface and / or provided with a traffic surface covering, in particular a pavement covering or an asphalt surface.

Particularly stable is an embodiment in which each anchoring device includes struts. In particular, it can be advantageously provided that the struts are surrounded by a hardened filling material, in particular concrete.

It has also been found that by using a special anchoring device, the plurality of struts whose longitudinal direction is aligned perpendicular to Absperrpfahl and towards the mounting end, a very safe drive anchorage of the Absperrpfahl can be achieved even if the anchoring device in the ground only is arranged at shallow depths.

By fixing the lower attachment end of the Absperrpfahles to several differently oriented struts of the anchoring device, in particular struts that are part of a truss, it is ensured that the forces that occur against the bollard in a land vehicle impact are distributed to different areas of the anchoring device. In particular, it is effectively achieved in this way that the Absperrpfahl does not dissolve in an impact of a land vehicle from the anchoring device.

Although simulation tests have shown that the individual components of the shut-off device permanently deform when a land vehicle collides, a disruption of the structures is effectively avoided by the inventive arrangement of the, in particular differently oriented, struts and the associated distribution of the forces occurring. This is especially true if the anchoring device is additionally filled with a hardenable material, in particular concrete, which additionally stiffens the anchoring device.

In addition, it is provided in a particular embodiment that not only the anchoring device as such, but also the space above it to the earth's surface with a curable material, in particular concrete, is poured out. This has the particular advantage that the inertial mass of the overall system is particularly high, which has a positive effect on impact of a land vehicle in order to absorb the impact energy. In a collision of a land vehicle against the Absperrpfahl the complex formed from the shut-off device including the concrete block is supported against the ground in the direction of travel behind it, so that the impact forces effectively into the ground can be initiated. However, this embodiment has the disadvantage that a simple and quick removal of the arrangement according to the invention or of parts thereof is not possible.

In a particular embodiment, the struts are fixed, in particular form-fitting and / or materially bonded, connected to the attachment end of the Absperrpfahles. In particular, it can be advantageously provided that the, in particular differently oriented, struts are welded directly to the attachment end of the Absperrpfahls. However, such a design does not offer the opportunity to temporarily remove the Absperrpfahl.

Therefore, it may alternatively be provided that the anchoring device has a receiving element into which the attachment end of the Absperrpfahles can be inserted if necessary. In such an embodiment, instead of the Absperrpfahl the receiving element, which may be formed, for example, as a sleeve, fixed, in particular form-fitting and / or material fit, connected to the struts, in particular welded.

For example, with a view to preventing the shut-off device according to the invention from driving over a 7.5 ton truck at a speed of 80 km / h, the sleeve may be made, for example, of steel with a wall thickness in the range of 20 mm to 40 mm and a height of 600 mm formed and welded directly to the struts. The sleeve may have an inner diameter of 254 mm, so that a bollard with matching outside diameter of, for example 250 mm, which may be formed in particular as a solid material post made of steel, embedded from above and can be removed if necessary. For example, can be advantageously provided that the sleeve is made for example of steel and has a wall thickness in the range of 40 mm to 60 mm. The sleeve may for this purpose have an inner diameter in the range of 200 mm to 300 mm, in particular of 254 mm, so that a bollard with a corresponding outer diameter, which may be formed in particular as a solid material post made of steel, embedded from above and can be removed again if necessary ,

An additional attachment of the Absperrpfostens is possible, but usually not required, since the bollard itself has a very high weight and because the post automatically jammed in the impact of a land vehicle in the sleeve that unwanted tearing out of the sleeve does not occur.

The bollard can have, in particular arranged under a removable cover, internal thread into which a hook can be screwed. The screw hook makes it possible to attach the spacer post to a crane hook in order to install or remove it.

As already mentioned, the anchoring device can advantageously be cast as a finished part with a hardenable material, in particular with liquid concrete. For this purpose, the anchoring device, for example, have an outer frame and a bottom plate, which together form an upwardly open trough for the curable material. Since the pouring out with a hardenable material already takes place during the production of the finished part, there is no loss of time at the construction site when installing the arrangement according to the invention, because there is no need to wait for hardening, such as the hardening of concrete.

As already mentioned, the struts can advantageously be part of a truss. In particular, the frame may be part of a truss structure of the anchoring device together with the struts. In particular, it is advantageously possible that at least one of the struts is also a frame part of the frame at the same time.

The frame may be formed from a plurality of frame parts, which are positively and / or cohesively connected, in particular welded, are. In addition, the frame parts are preferably fixedly connected to the bottom plate, in particular welded. In general, it can be advantageously provided that the frame is assembled from frame parts, in particular welded, wherein at least one of the frame parts as Breitflanschträger and / or as a profile carrier and / or T-shaped carrier or as a double-T-carrier or as a flat plate is. As far as one of the struts is formed as a flat plate, it is of particular advantage in terms of stability, when the main plane of the plate is vertically aligned. As far as one of the struts is designed as a wide-flange carrier, in particular as a double-T carrier, it is of particular advantage with regard to the stability of the anchoring device if the flanges are oriented horizontally, while the web is aligned vertically.

In a particular embodiment, the anchoring device is substantially, apart from any existing receiving elements for inserting bollards, cuboid shaped.

It has been found that an embodiment of the anchoring device having a length in the range of 1,500 mm to 2,800 mm, in particular of 2,000 mm, a width in the range of 1,000 mm to 1,400 mm, in particular of 1,200 mm, particularly compact and yet special can be stably formed. In particular, the anchoring device may have a height in the range of 100 mm to 500 mm, in particular 450 mm. The anchoring device may advantageously be formed in particular substantially plate-shaped. In particular, the anchoring device can advantageously have a weight in the Range of 2 t to 4 t, in particular in the range of 2.7 t to 3.1 t, in particular of 2.9 t. Such a design allows on the one hand a sufficiently good handling when delivering and placing in the pit and on the other hand a sufficiently large inertia.

In particular, such an embodiment can be made using components of DIN raw material such that the installed shut-off device can not be run over by a truck weighing 7.5 tons at a travel speed of 80 km / h.

In a particular embodiment, the shut-off device has at least one further Absperrpfahl whose attachment end is fixed to the anchoring device or can be fixed. For this purpose, the anchoring device may advantageously have a plurality of further struts whose longitudinal extension direction are aligned perpendicular to the further Absperrpfahl and in the direction of the fastening element of the further Absperrpfahles. Such an embodiment may be formed correspondingly wider.

As already described above in relation to the Absperrpfahl, and the other Absperrpfahl can either be directly connected to the struts, in particular welded, or be inserted indirectly via a firmly connected to the other struts receiving element. The latter has the particular advantage that the additional Absperrpfahl can be temporarily removed if necessary.

Preferably, the anchoring devices of the arrangement according to the invention are the same, in particular at least the same size, formed. Such an embodiment allows a cost-effective production, because the same parts can be produced. Nevertheless, such an embodiment is particularly flexible as already mentioned, by the use of different fasteners in particular a laying of anchoring devices in an arch shape just as possible, as a straight-line installation, with a straight-line installation preferably equal in size fasteners are used.

With regard to the method according to the invention, the production of the pit is preferably carried out in such a way that a flat, horizontal bottom results at the bottom of the pit. Preferably, a pit is made with vertical walls. A horizontal, level bottom of the pit can be achieved, for example, that a fine-grained granules, such as gravel or sand, filled in after digging soil in the pit and then pulled off horizontally. On the level and horizontal bottom of the pit can then the anchoring devices are placed.

After placing the anchoring devices in the pit connecting each adjacent anchoring devices by means of at least one connecting element takes place. In this way, it is advantageously achieved that a force on the Absperrpfahl a shut-off must not be caught only by the affected shut-off, but that rather a partial transmission of the force on the adjacent anchoring devices and possibly of these on the next but one anchoring devices, so that the shutters support each other as a whole.

In a particular embodiment, adjacent anchoring devices (apart from being indirectly in contact with each other via the ground or the filling material or the traffic lining) are connected to one another exclusively by means of one connecting element or a plurality of connecting elements, in particular in a form-fitting or exclusively positive manner. In particular, it can be advantageously provided that adjacent anchoring devices are connected exclusively by means of a connecting element or a plurality of connecting elements such that tensile forces can be transmitted.

Preferably, the space between the anchoring devices and / or at least part of the space above the anchoring devices and above the intermediate spaces are filled with a filling material. The filler material preferably does not include a hardening material, such as concrete. This has the particular advantage that you have to wait for the curing. Rather, it is possible to produce directly on the filler a traffic surface coating, in particular a pavement or an asphalt pavement. For example, the filler may consist of excavated material or may include portions of the excavated excavated pit. Alternatively or additionally, it is also possible that the filling material contains gravel or gravel or sand.

Preferably, the spaces between the anchoring devices are filled with filling material used in road construction, in particular with gravel or gravel, and the filling material is compacted to a proctor density of at least 98% to 103%. The filling of the spaces between the anchoring devices is preferably carried out to the upper edge of the anchoring devices, so that a total of a flat surface is formed. Subsequently, a traffic surface covering can be applied to the flat surface. For the traffic surface covering in particular a height of 15 cm can be provided.

In a particularly advantageous embodiment is above the Anchoring devices and above the, preferably filled, spaces between the anchoring devices a traffic surface covering, in particular a pavement or an asphalt pavement made, the traffic surface covering rests directly on the anchoring devices. In such an embodiment, it is only necessary to fill the spaces between the anchoring devices with a filling material. Again, it is advantageous that it is not necessary to use a hardening filler. For example, the filler may consist of excavated material or may include portions of the excavated excavated pit. The filling material may also be gravel or gravel or sand.

In a particular embodiment, at least one of the anchoring devices rests on the top or has an anti-slip coating. Such an embodiment has the particular advantage that the immediately adjacent traffic surface covering, in particular a pavement covering or an asphalt surface, does not slip, for example when a vehicle drives over it.

Preferably, then the anchoring device and the space above it to the earth's surface with a curable material, in particular with liquid concrete, poured out. In the event that several shut-off devices are installed, all anchoring devices are simultaneously and together with the lying on the anchoring devices space to the surface of the earth with the curable material, in particular liquid concrete, poured out. In this way, it is advantageously achieved that the anchoring devices are additionally connected to one another via the curable material. In addition, the forces acting on the bollard of a shut-off device in the event of a landing of a land vehicle are effectively transferred to the adjacent shut-off devices and the entire common concrete block, so that the overall structure as a whole is particularly stable, robust and massive.

three interconnected shut-off devices according to the fourth embodiment, wherein for better illustration in one of the Absperrpfahl and one of the concrete casting is not shown.

FIG. 1 shows a perspective view of an embodiment of an inventive arrangement of several shut-off devices 21 for preventing the passage of land vehicles, especially trucks. Each shut-off device 21 has a shut-off pile 1. In addition, each shut-off device 1 as a prefabricated part, especially precast concrete, trained anchoring device 3, on which a fastening end of the Absperrpfahles 1 is fixed or can be fixed and which is designed and intended to be so arranged, in particular invisible, below the earth's surface, that the Absperrpfahl 1 protrudes vertically from the earth's surface.

After the anchoring devices 3 have been deposited in the pit, the respectively adjacent anchoring devices 3 are connected by at least one connecting element 22. The connecting elements 22 are designed as plug-in elements, which only needs to be plugged in to connect adjacent anchoring devices 3. The connecting element 22 are U-shaped and have two mutually parallel legs 23 which are fixedly connected to each other via a web 24.

For connecting adjacent anchoring devices, a leg 23 is inserted from above into an opening 25 of one of the connecting elements, while the other leg 23 is inserted into an opening 25 of an adjacent anchoring devices. The openings 25 serve as coupling elements for coupling the connecting element 22.

In the embodiment shown, connecting elements 22 of equal size are each used to connect two adjacent anchoring devices 3, because the anchoring devices 3 are to be aligned parallel to one another. Alternatively, it would be possible to use unequal connection elements 22 if two anchoring devices 3 are not aligned parallel to each other, for example in order to achieve an overall arcuate arrangement of the anchoring devices 3.

FIG. 2 shows a perspective view of one of the shut-off devices 21 of in Fig. 1 shown arrangement, wherein the Absperrpfahl 1 with its attachment end 4 in a receiving element 19, namely a sleeve, the anchoring device 3 is inserted.

FIG. 3 shows a cross-sectional view through a built-in pit 17 shut-off device 21 of an inventive arrangement of several shut-off 21. The anchoring device 3 of the shut-21 is at the bottom of the pit 17, which was prepared for example with a depth of 600 mm. stored. The pit 17 has been made to have a flat, horizontal floor on which the anchoring devices 3 can be laid out horizontally. In particular, it is not necessary at the bottom of the pit 17 before the introduction of the shut-off consuming 21 to create a foundation. Preferably, only a bulk material, such as fine-grained gravel, filled and withdrawn horizontally, so that the withdrawn surface of the bulk material forms the horizontal and flat pit floor on which the anchoring devices 3 can be placed.

Above the anchoring device 3 and above the (not shown), preferably filled, spaces between the anchoring devices 2 is a traffic surface covering 26, in particular a pavement laid 27, wherein the traffic surface covering rests directly on the anchoring device 3.

FIG. 4 shows a different embodiment of a shut-off device 21 according to the invention for preventing the passage of land vehicles, in particular of trucks. The shut-off device 21 has a shut-off pile 1 and a further shut-off pile 2. In addition, the shut-off device 21 has an anchoring device 3, on which a fastening end 4 of the Absperrpfahles 1 is fixed. In addition, the anchoring device 3 a plurality of struts 5, 6, 7, 8, 9, the longitudinal extension direction are aligned perpendicular to Absperrpfahl 1 and in the direction of the attachment end 4.

It is envisaged that for producing an inventive arrangement more of the in FIG. 4 anchoring devices 3 shown by means of connecting elements, in particular non-destructively releasably connected again. In particular, it can be advantageously provided that several of the in FIG. 4 Anchoring devices 3 are connected to each other as shown in the in the FIGS. 1 and 2 illustrated embodiment takes place.
In addition, the anchoring device 3 has a plurality of further struts 10, 11, 12, 13, whose longitudinal extension direction are aligned perpendicular to the further Absperrpfahl 2 and in the direction of the attachment end 14 of the further Absperrpfahls 2.

The struts 5, 6, 7, 8, 9 are welded end to the attachment end 4 of the Absperrpfahles 1. Analogously, the further struts 10, 11, 12, 13 are welded to the attachment end 14 of the further Absperrpfahls 2. The strut 9 is welded at one end to the Absperrpfahl 1 and welded to the other Absperrpfahl 2 at the other end.

The anchoring device 3 has an outer frame, which is joined together from frame parts 15 welded together. Here, the struts 8, 9 and 13 fulfill a dual function. The struts 8, 9, 13 additionally act as frame parts 15.

The struts 8, 9 and 13 are each formed as a T-beam made of steel. The remaining frame parts 15 are formed as plates. The struts 5, 6 and 7 and the other struts 10, 11 and 12 are arranged in the same (horizontal in the installation position) level as the frame formed by the frame members 15.

The anchoring device 3 also has a bottom plate 16, which is welded to the frame parts 15 and the struts 5, 6, 7 and the other struts 10, 11, 12. The frame and the bottom plate 16 together form an open-topped pan, in which a curable material, in particular liquid concrete, can be filled.

The Absperrpfahl 1 and the further Absperrpfahl 2 are circular cylindrical and preferably made of a solid material, in particular made of steel. The remaining parts of the anchoring device 3 may be advantageously made of steel.

Especially in the FIGS. 4 . FIG. 5 and in FIG. 6 It can be seen that the strut 6 and the further strut 11 as Breitflanschträger, namely as a double-T-carrier, are formed, which are each circular-cylindrical cut such that they form-fitting to the Absperrpfahl 1 and the other Absperrpfahl 2 added and welded can be.

The anchoring device 3 is constructed like a truss, wherein in particular the struts 5, 6, 7 and the other struts 10, 11, 12 are each assigned to a node of the truss, in which a fastening end of the Absperrpfahls 1 and the other Absperrpfahls 2 is arranged.

FIG. 9 shows quite schematically a shut-off device 21 according to the other embodiment, which is installed in the ground. The shut-off device is arranged in a pit 17 which has been made, for example, with a depth of 600 mm. The pit was made to have a flat, horizontal floor on which the Anchoring device 3 with the outside of the bottom plate 16 can be designed to be aligned horizontally. The Absperrpfahl 1 and the other (in FIG. 6 not visible) Absperrpfahl 2, which are fixed to the anchoring device 3, project vertically out of the pit 17. In particular, it is not necessary to elaborately create a foundation at the bottom of the pit 17 prior to the introduction of the shut-off device. Preferably, only a bulk material, such as fine gravel, filled and withdrawn horizontally, so that the withdrawn surface of the bulk material forms the horizontal and level pit floor, on which the shut-off device can be placed.

After the anchoring devices 3 have been introduced into the pit 17, they are connected to each other by means of connecting elements 22 (not shown in this figure).
