This invention relates to apparatus for the creation of outer surfaces having certain effects for structures. In particular, the invention relates to gabion facades and to gabion inserts.
In European Patent No. 0466726, there is set forth a cage structure useful in connection with the creation of building blocks, which can be used for sea defences, shoring hillsides, and for providing military defence walls. These structures are made of open mesh panels, for example of welded mesh material, or twisted wire construction. The advantage of the structure set forth is that the panels are used to form the walls of the structure, with the panels being pivotally connected under factory conditions and the structure can be folded to a flat collapsed condition for transportation to site. On site, simply by manipulation, the structure is capable of being moved from the collapsed condition to an erected condition, in which the structure defines a row of open topped cavities which can be filled with soil, sand, rubble or the like to form a wall (or part thereof), shoring block or the like. The invention has been successful commercially on a worldwide basis.
The type of gabion described in EP-B-0466726 has applications in the military field, as well as in civil and environmental defence. Other types of gabion have applications in landscape design and in decorative or aesthetic connections, such as garden ornaments or window boxes. It may be desirable in some circumstances to provide such gabions with a surface effect which allows the gabion fill material to be obscured from view by a surface effect material in use of the gabion.
As well as aesthetic reasons for providing a surface effect, a problem which has been encountered with some gabions is that in certain climates, particularly hot climates, the material which is used to fill the cavities formed by the panels can be susceptible to changing conditions under temperature extremes. For example the material may be caused to contract in cold weather or expand in hot weather which can cause the structure to be less rigid or threaten to “burst” the joins between the panels.
A further problem is that in certain instances it can be desirable to provide a building structure with a particular surface effect, which it might not otherwise have from the material used to fill the cavities.
It should be clear that the invention can be applied to other building structures and situations. This should be borne in mind despite the fact that in the following a structure of the type described in the applicant's patent EP0466726 is given as a particular embodiment of the invention. Other types of gabion are particularly susceptible to improvement with this invention.
In a collapsible/erectable structure it is difficult to give the walls, or one wall a different surface effect than would be achieved as a result of the materials used for the structure and the filling material. It is disclosed in the said patent that when the structure is erected and filled, the walls can be given a different surface effect by the spraying of decorative synthetic resin onto the walls of the erected structure. However, it may be desirable that the walls were to have a different surface effect, say of aesthetically attractive materials such as pebbles, turf or of other vegetation effect, or a surface effect for protective purposes that could not be achieved with the structure specifically described in the said patent.
The present invention provides an apparatus whereby an outer surface can be provided, which is other than the surface which would be achieved without the invention with the located surface effect being of advantage from an appearance effect and/or in controlling the condition of the building structure.
Accordingly, the present invention provides cage structure comprising opposed side walls connected by opposed end walls defining a cage cavity therebetween, the cage structure being provided on at least one side or end wall with a façade spaced from said side or end wall to an extent sufficient to accommodate a surface effect material between the at least one side or end wall and the façade.
Preferably the façade comprises a material which permits viewing of the surface effect material when thus accommodated.
Also provided is a cage structure comprising opposed side walls connected by opposed end walls defining a cage cavity therebetween, the cage structure being provided on at least one side or end wall with an insert spaced from said side or end wall to an extent sufficient to accommodate a surface effect material between the at least one side or end wall and the insert. Preferably the side or end wall on which the insert is provided comprises a material which permits viewing of the surface effect material when thus accommodated.
The façade or insert may comprise a secondary cage structure comprising opposed side walls connected by opposed end walls defining a cage cavity therebetween.
The cage structure may be in the form of a multi-compartmental gabion comprising pivotally connected side and end walls and at least one pivotally connected partition wall, the at least one partition wall separating individual compartments of the gabion. In this case the façade or insert may comprise a secondary cage structure in the form of a multi-compartmental gabion comprising pivotally connected side and end walls and at least one pivotally connected partition wall, the at least one partition wall separating individual compartments of the gabion.
The cage structure may be provided with a first fill material filled against the façade or against the side or end wall on which the insert is provided, and a second fill material filled behind the first fill material, the second fill material being a different material from the first fill material.
The present invention also provides a cage structure comprising opposed side walls connected by opposed end walls defining a cage cavity therebetween, the cage structure being provided on at least one side or end wall with a façade spaced from said side or end wall to an extent sufficient to accommodate a surface effect material between the at least one side or end wall and the façade, the façade comprising a material which permits viewing of the surface effect material when thus accommodated.
Also according to the present invention there is provided a cage structure comprising opposed side walls connected by opposed end walls defining a cage cavity therebetween, the cage structure being provided on at least one side or end wall with an insert spaced from said side or end wall to an extent sufficient to accommodate a surface effect material between the at least one side or end wall and the insert, the side or end wall on which the insert is provided comprising a material which permits viewing of the surface effect material when thus accommodated.
It will therefore be seen that the invention permits the adaptation of a gabion structure to provide a surface effect by blocking or partially blocking through at least one side or end wall of the gabion viewing of a gabion fill material located in the gabion by interposing between the viewer and the gabion fill material a surface effect material accommodated either on the outside of the said side or end wall (and retained in place by the façade) or on the inside of the said side or end wall (and retained in place by the insert).
The façade may for example comprise a mesh material which permits viewing of the accommodated surface effect material through the mesh holes. Alternatively, the façade may comprise a transparent material—such as glass, acrylic or Perspex™ in for example.
In the case of an insert, the side or end wall on which the insert is provided preferably comprises a mesh material which permits viewing of the accommodated surface effect material through the mesh holes.
If the surface effect material has a technical function rather than an aesthetic function, it is not necessary for the surface effect material to be viewable from the outside. Thus, if the surface effect material has anti-corrosive properties, for example, the façade or the side or end wall on which the insert is provided may be opaque
The façade or insert is preferably connected to the side or end wall on which it is provided, or may be connected either side of said side or end wall to neighbouring pairs of side, end walls. In the case of a multi-compartmental gabion, an insert may alternatively (or also) be connected to one or more partition walls neighbouring the side wall on which the insert is provided (partition walls in this case being the walls dividing compartments of a multi-compartmental gabion)
Such connection is preferably achieved by suitable mechanical means, for example one or more connectors, clips, ties or fasteners.
The connection, particularly in the case of a façade, may be removable. That is to say, the connector(s), clip(s) tie(s) or fastener(s) may be releasable or removable to allow detachment, or partial detachment, of the façade or insert. Such connection may be pivotal (one edge of the façade or insert being pivotally connected to a corresponding edge of the side or end wall, for example), or the façade or insert may be completely removeable from the side or end wall.
In accordance with the invention there is provided an apparatus for creating an outer surface of a structure wherein at least one wall of the structure defines a support surface, the apparatus comprising means defining a covering surface which overlies the support surface but is movable therefrom, so that a quantity of material to create the outer surface can be positioned between the support surface and the covering surface, and wherein the covering surface is in the form of a panel. When the surface effect material has an aesthetic quality, typically the panel is a mesh panel or transparent panel through which the said surface effect material can be viewed.
In accordance with the invention there is provided an apparatus for creating an outer surface of a structure wherein at least one wall of the structure defines a support surface, the apparatus comprising means defining a covering surface which overlies the support surface but is movable therefrom, so that a quantity of material to create the outer surface can be positioned between the support surface and the covering surface, and wherein the covering surface is in the form of a panel. Typically the panel is a mesh panel or transparent panel through which the said surface affect material can be viewed.
Preferably, the support surface is defined by a mesh panel, and the edges of the cover panel are connected to the edges of the support mesh panel by means of suitable connectors. Suitable connectors may be in the form of elongated, coiled wire connectors threaded round the edges of the mesh panels at a pair of opposite edges of such panels, or threaded about intermediate spacing panels which serve to space the outer panels from the support of the structure.
Preferably, the structure is defined by a series of mesh panels, and the edges of the cover panel are connected to the edges of the support mesh panel by means of elongated, coiled wire connectors threaded round the edges of the mesh panels at a pair of opposite edges of such panels, or threaded about intermediate spacing panels which serve to space the outer panels from the support of the structure.
In one embodiment, the cover panels can be pivoted away from the support panel, or be removed therefrom to a sufficient extent to allow a cavity to be formed for the reception of the material to create the outer surface. The material can for example be a layer of turf or other horticultural vegetation, or decorative wood planks, board, or wooden fencing members (such as chestnut fencing poles), rocks, boulders, gravel to be placed on the support panel, or within the cavity. The cover panel can if required be positioned to retain the said material and again if required be connected, by re-threading the coiled wire connector through the edges of the cover and support panels, to trap the material in position between the panels.
The cover panel may be detached completely by removing both coiled wire connectors, or if the cover panel is mounted so as to lie spaced from the support panel to a sufficient extent, then the material may be positioned between the panels without removing the cover panel.
The support panel may be a wall panel of a collapsible structure as described above. Indeed, and as can be expected, all of the wall panels of one or both sides of such a structure may be provided with a surface effect as set for the above. The outer surfaces for the individual wall panels will usually be the same, but they could be different as desired. The invention also extends to a structure as described above, but wherein the various panels, or at least some of them are delivered to site, and the structure is erected on site by connecting the panels together, the outer surface being added after erection of the structure, or in an alternative arrangement, each support panel and its cover panel may be pre-connected and constructed to receive the material to form the outer surface therebetween.
Where the outer surface is created by growing material, this may eventually grow to such an extent as to conceal the cover panel mesh, and so using the collapsible structures mentioned above, could provide a quick means of erecting say a grassy bank, or a boundary hedge wall, which would have a natural look, without the need for any excavation. The invention therefore has considerable advantages. The invention may also have advantages in garden and landscape design, allowing the erection of structures having pleasing outer surface effects created with minimal use of an outer surface effect material.
A further advantage is that by selecting the appropriate material to form the outer surface, so heat insulation can be achieved by the said material thereby preventing adverse effects from the heat on the structure or the filling material or on other items adjacent the structure.
Typically, each or selected sides of the structure can be provided with the panels thereby allowing an outer surface to be created on all or selected sides of the structure. In addition, the material used to form the outer surface can also be positioned on the top of the structure to form an outer surface thereon.
In a further aspect of the invention there is provided a structure comprising a series of interconnected side panels forming a cavity for the reception of filling material therein to form a building structure having opposing side walls and end walls and wherein additional panels are provided along at least the side walls, externally thereof and joined to the same but spaced apart to form respective first and second cavities for the reception of material which differs to the filling material and form outer surfaces along at least the side walls.
In one embodiment the material used has better insulating characteristics than the filling material.
By way of explanation, an embodiment of the invention, with modifications, is illustrated in the accompanying diagrammatic drawings, and is explained in the description which follows.
In
The structures 12, 14 and 16 have no top or bottom, so that each defines a row of cavities 20, 22, 24 and so on, and the structures can be of any appropriate length. Typically, the structure may be of 10 cavity lengths but this is not to be considered as limiting.
In a practical example, the inner surfaces of the panels of the structures 12, 14 and 16 are lined with a retaining material such as a geo-textile material so that when the structure cavities 20, 22 and 24 are filled with appropriate filling material such as soil, sand, rocks or other ballast, that material will not pass through the meshes of the panels, it being remembered that the panels making up the structure will normally be of welded mesh construction.
These structures and the features described are of course already known.
Of the panels 30 and 32, if the panel 30 is at the end of a structure, it will be an end panel, but panel 32 will be common to the next cavity, and it is commonly known as a partition panel. The spiral connectors which connect panels 26 and 28 to panel 32 therefore also simultaneously embrace the next adjacent side panels of the next cavity, and so on.
It will be understood that the structures depicted in
The structures 12, 14 and 16 need not be of trapezoidal form, but this form is of particular advantage in relation to the utilisation of the present invention.
In the present invention, the outer surfaces of the panels of the structures shown in
In order to provide the material to form the outer surface of the structure the panels 40 to 50 are pivoted clear of the side panels of the structures 12, 14 and 16, which side panels form support panels and the material can either be applied over the support panels as shown or placed into cavities defined between the support panels and cover panels. When the material is applied, the cover panels 40 to 50 are pivoted back onto the material, and are connected to each other by means of a coiled wire connector such as 18 at the free edges which are shown in
Instead of placing turf between the support and cover mesh panels, other suitable horticultural material can be used such as the material known as “seedam” which is a material which is supplied as a thin layer and in rolls, and is simply unrolled and placed on the ground. The layer comprises soil bound by means of a woven fabric, and the soil contains a seed material from which green vegetation grows.
The Seedam material is so constructed that the soil and binding fabric will retain moisture enabling the vegetation 52 to grow efficiently, but the addition of the geo-textile material 60 provides a further means for the retention of moisture, and the invention therefore is of particular relevance to the effective growing of the Seedham material. The Seedam material provides an excellent green covering and growth is limited as compared for example to grass so that cutting of the Seedam material is not necessary and therefore it is particularly suitable for this application.
Instead of the panels 40 to 50 being pivotally mounted as shown in

A further possible embodiment of the invention may be contemplated in which the panels are provided with integrally formed limbs. Each limb may have a return that can engage a part of the gabion. In use, a layer of decorative material such as turf is interposed between the gabion and the panel. The panel is pressed against the gabion causing the decorative layer to compress. The limb bends to pass a wire of the gabion. Releasing the panel allows the decorative layer to expand back to its original dimension thereby causing the return of the limb to engage a wire of the gabion. Limbs can be provided instead of the aforementioned hinge-engaging fasteners or supplementary thereto. Additionally or alternatively, one or more limbs may be disposed towards the centre of each panel to inhibit bowing-out of the panel in use, which adverse effect may occur over time, e.g., as grass/vegetation root systems establish.
In this invention it is not necessary that the structures are erected in the factory. They could be erected on site, where some or all of the pivot connections are made, and the surface effect material could be inserted in the erected structure on site or it could be supplied between the support and cover panels and supplied as panel units.
The invention provides a means of adding to the functionality and/or the aesthetic appeal of a gabion structure. Thus, if it is desired to provide a gabion structure with an exterior surface effect for aesthetic reasons, this can be achieved by using a surface effect material with aesthetic properties. Alternatively, if it is desired to provide a gabion structure with an improved functionality (e.g., resistance to weathering, corrosion, heat expansion, water penetration and the like) then a suitable functional material can be selected as the surface effect material.
The invention provides that an outer surface on the side walls of the structure can be created by using a covering mesh panel, where such effects either visual and/or protective would not normally exist. The invention has particular application to the collapsible type structures discussed herein, and can be used to maintain the characteristics of the same in extreme environmental conditions by preventing expansion or contraction and hence improving the safety of the structures as required.
