Description:
Transferable Multipurpose Barrier and a Method of Manufacturing a Wall Piece.

Technical Field

The invention relates to a transferable multipurpose barrier, consisting of dismountable units each unit being provided with a wall piece and at least one wall support and further relates to a method of manufacturing a wall piece.

Background of the Invention

Houses and other buildings are at most places built at places liable to face a danger of a natural calamity, namely at places near to water streams, steep slopes or rocks. At many such places a dangerous situation could be predictable nevertheless people feel themselves in safety as after many years of peaceful life they no more realize what could happen or they even underestimate the circumstances.

Due to rapid climate change one faces floods and land-slides even at places which had been thought to be peaceful and safe. This fact requires erection of constructions and facilities which are to protect the areas in danger against such disasters. Nevertheless it is not always possible to build permanent constructions everywhere. Therefore there are manufactured and erected temporary constructions which are used only during periods as may be required and otherwise they are stored in safe places. Basically there exist two types of such temporary barriers. The first type is designed for an application at a selected place, where in advance there are prepared anchor means like loop or hooks or, as the case may be, reinforced hole for insertion of support posts. An example of such an embodiment is described in the paper US 6042301 , the embodiment comprising vertical support posts made of l-profile beams and a system of crossbeams stacked one above the other thus filling gaps between the posts. A similar solution is described also in a paper FR 2843411. Such a system with dismountable posts and intermediate dismountable walls has been installed also in Praha after disastrous floods in 2002. Very important disadvantage of the design consists in necessary anchor means which are to be built in advance and which have to be secured against undesired blocking by impurities and filthiness. The second type barriers comprise systems which may be utilized everywhere, provide their construction enables an application in the given terrain. An example of such a design is described in DE-GM 20315154. The said barrier consist of elements basically having a shape of a horizontally oriented, hollow triangular prism without both bases and the bottom wall being substituted by connecting and anchoring elements. One of the walls faces the direction from which a water flow is expected, the other wall is a support of the first one. Obvious disadvantage of such a barrier includes difficult transport and labour demanding assembly, requiring mechanical means. The patent application CZ PV2008-252 describes a barrier which consists of dismountable individual units comprising a base and a wall with at least one support, the base being provided with wall anchoring means and support anchoring means and the wall having a rigid frame. The barrier design manifests disadvantages comprising a very robust wall support and first of all insufficient interconnections of adjoining walls. The paper EP 1262602 deals with a transferable barrier with at least one wall shaped element which is supported by at least two dismountable supports. A contact joint between each wall and a ground surface is covered by a sheet. Nevertheless the paper solves neither the problem of a contact joint between two adjacent wall nor design of individual wall units which for a transferable barrier have to be rigid but not excessively heavy. Only a support construction is described in an utility design AT 006490 U1. The said support is covered by sand bags to face coming water. Just the application of sand bags is a complicated matter and requires lot to time to complete a barrier at desired place.

It is an object of the invention to create a barrier which can be manufactured under low costs, can be easily transportable at a place of need and then easily assembled by several workers, without mechanical means as the case may be. Moreover the barrier has to be a multipurpose one, applicable also in other events than water floods.

Disclosure and Object of the Invention

The foregoing problems are solved by a transferable multipurpose barrier, consisting of dismountable units each unit being provided with a wall piece and at least one wall support where in accordance with the present invention a wall piece of each of the barrier units comprise a board made of a composite material and is provided with reinforcing frame made of a composite material as an integrated element connected with the board by means of a bonding agent and a continuous layer of a top coat covering the frame as well as the respective surface of the board. In a preferred embodiment the frame cross-section has a shape of a trapezoid with rounded edges, while at least one part of the trapezoid base is bended by 180°. Further in a preferred embodiment the composite material comprise a resin matrix with reinforcement material covered by a protective layer. Preferably glass-fibre mat, glass-fibre fabric and/or polypropylene or aluminium honey-comb structure and may comprise also aramid and/or carbon fibres are used as the reinforcement materials. The matrix preferably comprises polyester and/or vinyl-ester and/or epoxy resins.

Further in accordance with the present invention the board is provided with a flat packing located at the board bottom edge. In a preferred embodiment the adjacent units are interconnected by an intermediate piece, inserted on adjacent edges of two spaced apart adjoining walls. The intermediate piece comprise two elastic stripes spaced apart by means of a distance insert, the mutual distance of the elastic stripes corresponding to a thickness of the wall edge.

It is a further object of the invention to provide for a method of manufacturing the wall piece. According this aspect of the invention there is created a flat board consisting of a resin matrix and reinforcement layers and the composition then hardens by an ambient temperature. Separately in a form there is created a one-piece frame made also of laminated resin bonded reinforcement material. After partial hardening the frame is resin bonded to the board and the plate together with the frame is covered by a top resin layer. Then the complete wall is completed by a final hardening procedure.

The transferable multipurpose barrier according the present invention is designed for capturing and diversion of a water flow or to hold a slipping earth or rock stones. Due to the design, the barrier wall is easy to manufacture, manipulation with each part of the barrier is comfortable and assembly of the barrier requires no exceptional effort. The manipulation is facilitated by the fact the wall pieces comprise no metal reinforcement or parts which would increase its weight. The discussed barrier construction can be installed even under terrain conditions where heavy construction machinery is not applicable, as is the case in terrain with difficult accessibility or terrain soaked with water after long-lasting rain period. An installation of the barrier according the invention is limited neither by a character of the site nor by the barrier required length.

Fig. 10 presents an intermediate piece in a front view on the face side and on Fig. 11 there is the intermediate piece according Fig. 10 in a front view on its opposite side and Fig. 12 shows the intermediate piece according Fig. 10 in a cross-section.

Description of Preferred Embodiments

A barrier according the invention as seen from the front side is presented on Fig. 1. In this paper the term front side describes the side seen from the direction of expected water or earth flow, while the term back describes the opposite side. The barrier comprise dismountable units each of them being provided with a wall piece 1 to be arranged at a site directly on a ground or by means of a base 2 and resting against at least one inclined or vertically arranged support.

The wall piece 1 comprises a board 5 made of a composite material and provided with a reinforcement frame 6. The frame 6 is an integrated single-piece part also made of a composite material and by means of a resinous adhesive is bonded to the board 5 back surface. The said board 5 surface inclusive the frame 6 is covered by a continuous resin layer. The reinforcement frame 6 has substantially a trapezoidal cross-section and is attached to the board 5 back surface by its longer base. For wall pieces 1 to be installed on supports in an inclined position, as shown on Fig. 9, or in a vertical position as presented on Fig. 4 and Fig. 7, the trapezoidal cross-section longer base is divided into two parts, each of them being bended outwards by 180°. Both bended parts provide for surfaces contacting the board 5. Such an embodiment of the reinforcement frame 6 is shown on Fig. 3. The wall piece 1 designed for vertically arranged supports with an U-shaped or an H-shaped cross-section has a reinforcement frame 6 of a cross-section in a form of a trapezoid with rounded edges, but as seen from the frame 6 cross-section, presented on Fig. 5, only one part of the longer trapezoidal base is bended outwards by 180°. This bended part of the frame 6 faces inside the board 5 back surface, while the opposite frame 6 edges coincide with edges of the wall piece 1.

The applied composite material comprises reinforcement, a matrix and a protective top coat. Preferably the reinforcement is made of a glass-fibre mat, glass-fibre fabric and/or polypropylene or aluminium honey-comb structure and may comprise also aramid or carbon fibres or their combination. The matrix material depends on required mechanical properties of the wall piece and preferably it comprises polyester resin, or as the case may be even vinyl-ester or epoxy resins.

By manufacturing the wall piece 1 for the multipurpose barrier according the invention at first there is created a flat board 5 consisting of reinforcement layers and resin matrix and the composition is let to harden at an ambient temperature.

Separately in a form there is created a one-piece frame made also of laminated resin bonded reinforcement material. After partial hardening the frame 6 is resin bonded to the board 6 and the board 5 together with the frame 6 are covered by a resin topcoat and the unit is completed by a final hardening procedure. The wall piece 1 is resistible against a wide temperature range, from -30 °C to +50 °C, chemicals and with respect to applied reinforcement resists high mechanical stress without being damaged. Preferably the wall piece board is up to 3 m long and up to 2 m wide.

The wall piece 1 designed for barriers against water and for erection directly on the ground is provided with a longitudinal resilient flat packing 7 located at the wall piece bottom edge, as seen on Fig. 7. The flat packing 7 may be of various designs, according the purpose of installed barrier. The term bottom edge describes an edge of the board 5 which is to be in contact with a ground on the site. The resilient flat packing 7 provides for sealing of the wall pieces 1 against the ground surface and eventually compensates the ground unevenness.

On the wall piece 1 back there may be attached loops to facilitate manipulation. These loops are not shown on the drawings.

The wall pieces 1 arranged either side by side or completed with extension parts 18 above the wall pieces 1 are mutually interconnected by intermediate pieces 10, the design of which is presented on Figs 10, 11 , 12. The intermediate piece 10 is inserted on adjacent edges of two spaced apart adjoining wall parts. Each intermediate piece 10 comprise two elastic stripes 12,13 spaced apart by means of a distance insert 1 1 , the mutual distance of the elastic stripes 12,13 corresponding to a thickness of the wall piece 1 edge. In the presented embodiment the distance insert 11 is made of a hollow profile having a rectangular cross-section. The first stripe 12 on a future front side of the intermediate piece 10, i.e. on the outside of the insert 1 1 , is made of an elastic material and from both sides is supported by metal bands 14,15. Both the outside band 14 and the inside band 15 have their length and width shorter than respective dimensions of the elastic first stripe 12. The second elastic stripe 13 located on the inside of the insert 1 1 is made of a metal sheet. The outside band 14 and the second elastic stripe 13 are mutually interconnected by rivets 16. To facilitate manipulation the intermediate piece 10 may be provided with a handle 17 located at the intermediate piece 10 inside.

When applied in an open terrain the wall pieces 1 are installed by means of a base 2 and each of the wall pieces 1 is kept in a set position by at least one support 3.

On Fig. 9 there is presented an example of such a support 3. The support 3 comprise in parallel and spaced apart arranged two bars 31 ,32 mutually connected by a cross girder 33. A seat 34 to accommodate the wall piece frame 6 is positioned in a push fit at each one of the two bars 31 ,32. In the presented embodiment the bars 31 ,32 are made of tubes and there is a seat 34 is attached to a sleeve 35 set at an upper free end each one of the two bars 31 ,32. By moving the sleeve 35 along the bar 31 ,32 the length of each bar 31 ,32 can be adjusted to actual need. The sleeve 35 set position shall be fixed by means known as such, namely by a pin inserted into one of the holes in the sleeve 35 and the bar 31 as well. Alternatively the seat 34 may be attached at an end of a rod inserted into the bar 31 ,32. Position of the rod with respect to the bar may be fixed by the same as described above. When in operation the wall piece frame 6 rests in the seat 34. At the end opposite the seat 34 each bar 31 ,32 is provided with a tip 36. The tips 36 prevent undesired movement of the barrier with respect to original position on the site. Positioned above the tip 36 there are located means to hold the bars 31 ,32 in the base 2. On the cross girder 33 there is in a swing fit attached a strut 37 securing a position of the support 3. When in an upright position the strut 37 free end is anchored in the base 2. When providing for protection of buildings the walls and other parts of which can serve as supports, the wall pieces 1 are arranged practically in a vertical position. If it not possible to fix the wall piece 1 at the building wall 40, as shown on Fig. 4, there is used a vertical support pole 41 with inclined strut 42, the support pole 41 being attached by screws to a base plate 44, as presented on Fig. 7. The wall piece 1 fixed to the support pole 41 by means of screws or it may be inserted into a groove in the support pole 1 , the groove being lined with a seal 43 as presented on Fig. 6.

The complete construction of the above described barrier can be installed both in open-air grounds and on solid base such as pavement, asphalt or concrete road, etc. The same barrier design can be applied also for other purpose, like a protection against possible landslide.

Industrial applications

The present invention is designed for construction of transferable, i.e. temporary built barriers for preventing undesired water flow or floods or even landslip. The barrier can be installed in open-air grounds as well as in housing areas.
