Description

FIELD OF THE DISCLOSURE

The present disclosure relates to a security barrier comprising a front panel and a bottom panel, wherein in installed state of the security barrier the bottom panel is connected at an angle to the front panel.
The present disclosure also relates to a method of installing a security barrier on the ground, wherein a front panel and a bottom panel are provided, wherein the front panel is erected and the bottom panel is placed on the ground.

BACKGROUND

Security barriers are used to prevent people, animals etc. from intruding in a certain area. Many countries have one or several security barriers for protecting their national borders as such in order to prevent people from other countries from immigrating. Also industrial sites, nature reserves, military sites or other areas/grounds are surrounded with security barriers to prevent intrusion of people and animals. These security barriers need to be solid and strong in order to effectively stop potential intruders. They also need to be able to absorb impacts form vehicles such as cars, trucks etc. because people can attempt to destruct a part of the security barrier by crashing into the security barrier with a moving vehicle. Security barriers can be used for temporary, semi-permanent or permanent access protection of areas.
A common type of such a security barrier is a gabion-type security barrier comprising several front panels, side panels, bottom panels and rear panels. These security barriers have several compartments each confined by a said front panel, two consecutive side panels, a said bottom panel and a said rear panel. By placing a weight in these compartments, a said security barrier is kept in place. These security barriers have a certain strength and rigidity. These security barriers are not really apt to absorb impacts from moving vehicles. They are also prone to rupturing at the level of the connection of the different panels, when impact forces are exerted on them by moving vehicles. An example of such a security barrier is described in WO 2008/020247.

SUMMARY

It is therefore an object of the invention to provide a security barrier which is strong and solid and which is also apt to absorb impact forces exerted on them, such as impact forces caused by moving vehicles. An object of the invention is also to provide a method of installing such a security barrier.
The object of the invention may be achieved by providing a security barrier comprising

- a front panel and;
- a bottom panel;
  wherein, in installed state of the security barrier, the bottom panel is connected at an angle to the front panel, and wherein the security barrier comprises a reinforcement panel, which in installed state of the security barrier, covers at least part of the front panel, in order to double the said at least part of the front panel.

With ‘connected at an angle’ it is indicated that the panels do not extend in the same plane. The reinforcement panel covers and doubles at least part of the front panel. For this, the reinforcement panel preferably extends substantially parallel to the front panel. The angle between the reinforcement panel and the bottom panel is then substantially the same as the angle between the front panel and the bottom panel. By doubling at least part of the front panel, said at least part is strengthened and reinforced. An impact force exerted on the security barrier, for example on the front panel, will therefore be better absorbed and guided throughout the security barrier. Also there is less risk that the security barrier will rupture when an impact force is exerted on it.
In a preferred embodiment the reinforcement panel is connected to the front panel. Because of this connection, an impact force exerted on the security barrier, will be better absorbed.
Preferably, in installed state of the security barrier, the reinforcement panel covers at least the front panel adjacent to the connection of the front panel to the bottom panel. Vehicles normally drive on the ground on which the security barrier is placed. Also normally the bottom panel is placed on the ground. When the front panel is several meters high, this means that a vehicle, which crashes into the security barrier, will only contact a lower portion of the security barrier. It is therefore only necessary to double a lower portion of the front panel. By covering only a part of the front panel, material can be saved and installation of the security barrier can be simplified. Further preferably the reinforcement panel is connected to the bottom panel. Forces acting upon the security barrier are then also well guided from the reinforcement panel to the bottom panel, such that impact forces can be well absorbed.
In a preferred embodiment the security barrier is composed of at least two construction units, wherein a first construction unit of the at least two construction units comprises the front panel and wherein a second construction unit of the at least two construction units comprises the bottom panel and the reinforcement panel, wherein the security barrier can adopt at least two configurations, a first configuration being a compact configuration wherein the first and the second construction unit are separated from each other and a second configuration in installed state of the security barrier wherein the first and the second construction unit are connected. The first configuration is more compact and thus suitable for transport and storage. The security barrier can thus be delivered on site in its first configuration and then be transformed to its second configuration. The security barrier can comprise in its first configuration several separate first construction units and several second construction units which are connected to each other when installing the security barrier. By making use of several separate first and second construction units, the security barrier can be made very compact. With several standardized first and second construction units, it is also simple to create a security barrier of the desired length.
In a very preferred embodiment the reinforcement panel is pivotally connected to the bottom panel and the second construction unit is folded in the first configuration. The pivotal connection ensures that the second construction unit can be folded and thus can be made more compact. Preferably the panels are pivotally connected to each other at the level of their edges. The dimensions of the reinforcement panel then preferably do not exceed the corresponding dimensions of the bottom panel. Further preferably the first construction unit comprises multiple said front panels and the second construction unit comprises multiple said reinforcement panels and at least one said bottom panel. The front panels can also be consecutively pivotally connected to each other, such that they can be folded.
Preferably the security barrier comprises side panels which, in installed state of the security barrier, are connected at an angle to the front panel and are connected at an angle to the bottom panel. The side panels provide additional strength and solidity. They also work as wind bracing. Forces acting upon the security barrier, for example upon the front panel(s), are here also guided through the side panels such that impact forces can be better absorbed.
In installed state of the security barrier, the side panels preferably comprise unconnected edges, wherein at least one said edge is at least partially reinforced with a profile. A said profile causes the side panel to be less prone to inclination when forces are acting upon the security barrier. The profile thus reinforces the side panels, so that impact forces acting upon the security barrier can be better withstood and absorbed. Preferably every unconnected edge has such a profile and preferably each profile extends over substantially the entire length of a said unconnected edge.
Further preferably a said profile is a U-shaped profile. This is a simple form which can be easily manufactured and be put upon a said unconnected edge. Also with U-shaped profiles the best results are obtained. With H-shaped profiles and L-shaped profiles good results can be obtained. However H-shaped profiles comprise more material than U-shaped profiles to provide the same additional strength to the security barrier.
In a preferred embodiment with side panels, the first construction unit comprises at least two said side panels, which are pivotally connected to the front panel of the first construction unit. The pivotal connections ensure that the first construction unit can be folded and thus can be made more compact. Preferably edges of the side panels are pivotally connected to an edge of the front panel. The dimensions of each side panel also preferably extends within the corresponding dimensions of the front panel.
In a very preferred embodiment the security barrier comprises a strengthening panel, which in installed state of the security barrier is connected to the front panel and two consecutive said side panels, at a certain distance from the bottom panel. This strengthening panel ensures that impact forces exerted on the security barrier, for example on the front panel(s), are well absorbed by the side panels. The strengthening panel itself also absorbs said impact forces. Also the risk of rupture, when impact forces are exerted on it, is low.
More preferably the second construction unit comprises the strengthening panel. This strengthening panel is than preferably pivotally connected to the reinforcement panel of the second construction unit. When the bottom panel is then also pivotally connected to the reinforcement panel, the second construction unit can be compactly folded. Also such a second construction unit can be easily connected to the first construction unit by unfolding the second construction unit, placing the reinforcement panel against the front panel and for example connecting the reinforcement panel to the front panel.
Further preferably the strengthening panel extends, in installed state of the security barrier, substantially parallel to the bottom panel. Impact forces are well absorbed when the strengthening panel extends parallel to the bottom panel.
In a specific embodiment the front panel, the bottom panel, the strengthening panel and the reinforcement panel have rectangular shapes and the side panels have a pentagonal shape, wherein one part of each side panel has a right-angled triangular shape and is located above the strengthening panel in installed state of the security barrier and in which the other part of each side panel has a rectangular shape and is located below the strengthening panel in installed state of the security barrier. The angles between the front panel and the bottom panel, the front panel and the side panels, the strengthening panel and the front panel and between the strengthening panel and the side panels, are preferably 90°. A security barrier according to this specific embodiment is strong and solid and is well apt to absorb impact forces exerted on it by for example moving vehicles.
The said one part with a right-angled triangular shape is just as capable of withstanding forces as if it were rectangularly shaped, with the same dimensions as the dimensions of the straight sides of the right angled triangle. In addition it contains less material. A right-angled triangular shape is also easy to produce. The said other part has a rectangular shape in such a way that in combination with the reinforcement panel, and the bottom panel, a container can be formed. In an alternative embodiment the side panels have a stair shape.
Preferably the bottom panel is connected to at least three said side panels. In such an embodiment more than two side panels rest on the bottom panel. This ensures that the bottom of the security barrier is firm and solid such that the security barrier is well apt to absorb impact forces.
In a preferred embodiment, in the installed state of the security barrier, the security barrier comprises at least one container, confined on the bottom by the bottom panel, on its sides by two said side panels and on the front by the reinforcement panel, wherein the back of the container is open such that the container is accessible from the back. To provide extra strength and stability to the security barrier, extra weight can be placed on the bottom panel. With an open back this can be done easily by approaching the security barrier from the back and placing extra weight on the bottom panel. There is then no back panel that complicates the placing of extra weight on the bottom panel.
The bottom panel and the reinforcement panel are preferably covered with a UV-resistant material, such as geotextile, plastic, coir mat, . . . . If side panels are present, the side panels are also preferably partially covered with said UV-resistant material. In this manner it is possible to place something upon the bottom panel which is not UV-resistant, because the UV-resistant material will protect it. If a weight is placed on the bottom panel and/or if a container (when present) is filled, this UV-resistant material shields said weight or said container. Someone standing in front of the security barrier and looking at the front panel, will not see the weight and/or the inside of the container.
Very preferably the said panels are mesh panels. The mesh panels can for example comprise a first set of wires extending substantially parallel to one another and a second set of wires extending substantially parallel to one another, wherein the wires from the first set and the second set intersect, and where these intersect are mutually attached. With the term ‘wires’ elongate elements or rod-shaped elements are indicated. These wires are, for example, formed by pulling force or by extrusion and they can be made out of metal, plastic, etc. The wires can for example be welded together where they intersect in order to attach the wires. Welding indicates every operation or treatment, whether or not with the addition of welding materials or gluing materials or products and whether or not accompanied by a (local) heating of the parts to be connected, which creates a durable connection without external coupling means and with a substantially mechanical connecting function. The mesh panels can also be produced by making holes in solid panels and by stretching these panels as such to create a wire-shaped pattern.
Mesh panels can easily be manufactured in the desired strength and firmness. Also mesh panels comprise openings between their wires. Material can thus be saved. When monitoring a border or a protected area it is desired that one can see what is happening on the other side of the security barrier. With a security barrier comprising mesh panels, one can easily look through the security barrier to see what is happening. When it is not desired that people can look through the security barrier, the mesh panels can easily be blinded.
Further preferably, the wires of the first set are arranged, in a systematic way, alternately on both sides of the second set of wires. By systematically providing wires from the first set alternately on one side and on the other side of the wires from the second set, a stronger security barrier is obtained.
The object of the invention may also be achieved by providing a method of installing a security barrier on the ground, wherein a front panel and a bottom panel are provided, wherein the front panel is erected and the bottom panel is placed on the ground and wherein a reinforcement panel is provided and at least part of the front panel is covered and doubled by the reinforcement panel. By placing the bottom panel on the ground, it is indicated that the bottom panel is placed upon a ground surface. This surface may be located at ground level. However, it is also possible that a ditch or the like is dug out, before installing the security barrier. In this latter situation the security barrier is installed in this ditch and the bottom panel will at least be partially located below ground level. With the method according to the invention a strong security barrier is obtained. As already indicated in the description of the security barrier according the invention, a said reinforcement panel, that covers and doubles at least part of the front panel, strengthens the front panel and ensures that the security barrier is well apt to absorb impact forces exerted on it. Thus by simply providing in a reinforcement panel that doubles at least part of the front panel, a security barrier with the desired properties is obtained. With such a method also existing security barriers can be turned into a security barrier according to the invention.
In a preferred embodiment a first construction unit comprising the front panel is provided and a second construction unit comprising the bottom panel and the reinforcement panel is provided, wherein the first and the second construction units are connected to each other by connecting the bottom panel to the front panel and connecting the reinforcement panel substantially parallel to the front panel. With such a method the security barrier can be easily erected starting from a compact form, which can easily be transported and stocked.
Further preferably the second construction unit is provided in a first position where the bottom panel and the reinforcement panel are pivotally connected to each other and folded and the second construction unit is unfolded before connecting it to the first construction unit. In such a method, the bottom panel and the reinforcement panel are so provided that they are pivotally connected to each other, allowing them to be delivered in a compact and folded manner. Preferably they are pivotally connected to each other at the level of their edges and also preferably the dimensions of the reinforcement panel do not exceed the corresponding dimensions of the bottom panel.
In a preferred embodiment the first construction unit is provided with at least two side panels, wherein during the connection of the first and the second construction unit, the side panels are connected to the bottom panel and the reinforcement panel. By providing side panels, a security barrier with additional strength and solidity can be erected. These side panels also work as wind bracing. Such a security barrier is also better apt to absorb impact forces exerted on it.
Further preferably, the first construction unit is provided in a first position where the side panels are pivotally connected to the front panel and folded and the first construction unit is unfolded before connecting it to the second construction unit. Preferably the side panels are pivotally connected to the front panel at the level of their edges and also preferably the dimensions of the side panels do not exceed the corresponding dimensions of the front panel.
Also further, in a very preferred embodiment, the second construction unit is provided with a strengthening panel which is pivotally connected to the reinforcement panel, and during the connection of the first and the second construction unit the strengthening panel is connected to the side panels and the front panel. By providing such a strengthening panel, the installed security barrier will have more strength and solidity. The security barrier is also better apt to absorb impact forces exerted on it. The strengthening panel is pivotally connected to the reinforcement panel such that the second construction unit can be delivered compactly.
In a preferred embodiment, during the connection of the first and the second construction unit, a container confined by the bottom panel, the reinforcement panel and the side panels is formed, and the container is filled. The container is fit to be filled, for example by a weight. By filling the container, weight is placed on the bottom panel, such that the security barrier becomes more solid and is strengthened. The security barrier is then apt to absorb a greater impact force exerted on it. For example the weight can be a concrete block, a filled (big) bag, such as a bag filled with sand. If a filed bag is used as weight, the filled bag is preferably closed when using the security barrier, such that when an impact force is exerted on the security barrier, the bag remains filled and the bag retains its weight as such limiting the amount of movement of the security barrier, when experiencing impact forces. The bag can also be placed empty in the containers and then later filled e.g. with material surrounding the security barrier such as sand, rocks, etc.
The said bag is preferably made of a water-permeable material such as for example geotextile, coconut coir, perforated plastic, perforated metal, woven plastics or woven fibers. The bag should let water through, but should not let through the material with which it is filled. This is especially important if the bag is filled with sand. Because of the water permeability, the occurrence of water logging is avoided.
Further preferably, the container is filled before the strengthening panel is connected to the side panels. When the strengthening panel is not connected to the side panels, the container is easily accessible.
Preferably the bottom panel and the reinforcement panel are pivotally connected to each other by means of a spiral that connects an edge of the bottom panel with an edge of the reinforcement panel and a bottom edge of the front panel is provided with a spiral, wherein the said spirals are brought together until they engage in one another and wherein a rod is fitted in the said spirals for interconnecting the spirals in order to connect the bottom panel and the reinforcement panel to the front panel. By placing a rod into two interconnected spirals, a solid and strong connection between the panels is obtained, such that the security barrier can absorb greater impact forces and the security barrier is less likely to rupture when absorbing an impact force. Also with such a method it is easy to install the security barrier quickly. Further preferably, many of the interconnected panels are connected to each other with the aid of spirals. For example if the security barrier is composed of a said first construction unit and a said second construction unit, the connected panels of each construction unit are preferably interconnected to each other with the aid of spirals and the two constructions units are connected to each other by engaging spirals of the first construction unit with spirals of the second construction unit and putting rods through them.
In a very preferred embodiment the security barrier is a security barrier according to the invention as mentioned above.

DETAILED DESCRIPTION

FIGS. 1 and 2 show simplified representations of a security barrier (1) according to a first embodiment of the invention, in installed state of the security barrier (1). FIGS. 3 to 5 show parts of this barrier (1) and in FIG. 6 an alternative embodiment of a part of the security barrier (1) is shown. Of course other embodiments are possible.
The security barrier (1) of FIGS. 1 and 2 comprise one bottom panel (3), three front panels (2), three side panels (5), three reinforcement panels (4) and three strengthening panels (6). All these panels (2, 3, 4, 5, 6) are mesh panels. Those panels (2, 3, 4, 5, 6) are represented as a white surface. The meshes would make the figures unclear. Also not all panels (2, 3, 4, 5, 6) are indicated with their number for clarity reasons.
As can be seen in FIGS. 1 and 2, each front panel (2) is connected at an angle of 90° to the bottom panel (3), one or two said side panels (5) and a said strengthening panel (6). Further the bottom panel (3) is connected at an angle of 90° to the three side panels (5) and the three reinforcement panels (4). Each strengthening panel (6) is further connected at an angle of 90° to one or two side panels (5) an to a said reinforcement panel (4).
Each reinforcement panel (4) is connected parallel to a said front panel (2) such that it covers a bottom part of the respective front panel (2), that is adjacent to the connection between the bottom part (2) and the respective front panel (2), in order to double the bottom part of the said front panel (2). The unconnected edges of the side panels (5) are each reinforced with a U-shaped profile (8). The strengthening panel (6) extends substantially parallel to the bottom panel (3).
The front panels (2), the bottom panel (3), the strengthening panels (6) and the reinforcement panels (4) have rectangular shapes and the side panels (5) have a pentagonal shape, wherein the upper part of each side panel (5) has a right-angled triangular shape and is located above the strengthening panels (6) and in which the lower part of each side panel (5) has a rectangular shape and is located below the strengthening panels (6).
The security barrier (1) comprises two containers which are confined on the bottom by the bottom panel (3), on its sides by the lower parts of two said side panels (5), on the top by a said strengthening panel (6) and on the front by a said reinforcement panel (4), wherein the back of the container is open such that the container is accessible from the back. Further the security barrier (1) can have a fourth side panel (not shown), connected to the front panel (2) and to the strengthening panel (6) and the reinforcement panel (4) which are only connected to one side panel (5) in FIGS. 1 and 2, such that the security barrier (1) has three containers. Also a security barrier can be composed of several security barriers (1), as shown in FIGS. 1 and 2, such that a longer security barrier is obtained. The security barrier (1) as shown in FIGS. 1 and 2 is then a standardized construction module by which a security barrier of the desired length can be easily obtained.
The security barrier (1), shown in FIGS. 1 and 2, is composed of a first and a second construction unit (7 a, 7 b). The first construction unit (7 a) according to the first embodiment of the security barrier (1) is shown in FIG. 3. An alternative embodiment of the first construction unit (7 a) is shown in FIG. 6. The second construction unit (7 b) of the first embodiment of the security barrier (1) is shown in FIGS. 4 and 5.
The first construction unit (7 a), according to the first embodiment of the security barrier (1), comprises the three front panels (2) and the three side panels (5). These side panels (5) are pivotally connected to the front panels (2) at the level of their edges with the aid of spirals. As a result, the first construction unit (7 a) can adopt a compact configuration wherein the side panels (5) are folded up against the front panels (5). This improves the transportation and storage. The front panels (2) are provided with spirals, at the level where the edges of the reinforcement panels (4) are provided to be connected to the front panels (2). Also the side panels (5) are provided with spirals at the level where they are provided to be connected to the strengthening panels (6) and the bottom panel (3).
The first construction unit (7 a) as shown in FIG. 6 is similar, but it only comprises two front panels (2).
The second construction unit (7 b) as shown in FIGS. 4 and 5 comprises the bottom panel (3), the three reinforcement panels (4) and the three strengthening panels (6). These strengthening panels (6) are pivotally connected to the reinforcement panels (4) at the level of their edges with the aid of spirals, and the reinforcement panels (4) are connected to the bottom panel (3) at the level of their edges with the aid of spirals. As a result, the second construction unit (7 b) can adopt a compact configuration where the strengthening panels (6) are folded up against the reinforcement panels (4) and the reinforcement panels (4) are folded up against the bottom panel (3). This improves the transportation and storage. Also the other edges of each reinforcement panel (4) and each strengthening panel (6) and also the bottom panel (3), are provided with spirals to connect them to the first construction unit (7 a).
The security barrier (1) can adopt at least two configurations, a first configuration being a compact configuration wherein the first and the second construction units (7 a, 7 b) are separated from each other and each folded and a second configuration, in installed state of the security barrier (1), wherein the first and the second construction units (7 a, 7 b) are connected.
The security barrier (1) is delivered in its first configuration. Then each construction unit (7 a, 7 b) is unfolded. Then the first construction unit (7 a) and the second construction unit (7 b) are placed against each other such that the reinforcement panels (4) lean against the bottom parts of the front panels (2) and such that the front panels (2), bottom panel (3) and side panels (5) also take the right configuration and the spirals of the first connection unit (7 a) engage with respective spirals of the second construction unit (7 b). Rods are fitted through the engaged spirals as such to firmly connect the first construction unit (7 a) to the second construction unit (7 b).
Before the strengthening panels (6) are connected to the side panels (5) by engaging spirals connected to the strengthening panels (6) with spirals connected to the side panels (5) and putting a rod into the said engaged spirals, weights are placed on the bottom panel (3) as such to fill the containers and strengthen the security barrier (1). The strengthening panels (6) are then connected to the side panels (5).
The bottom panels (3), the reinforcement panels (4) and the lower parts of the side panels (5) are further covered with a UV-resistant material. This protects the weights placed upon the bottom panel (3) from UV-light and it also makes sure that a person, standing in front of the security barrier (1), cannot see the weight.
