Description

PAVING ELEMENT SYSTEM PROVIDED WITH A FLEXIBLA JOINT
The present invention relates to an element system for forming a paving, to a concrete element and to the use of the element system and of the concrete element for the purpose of forming a paving.
In the construction of streets use is now commonly made of bricks, such as clinkers and cobbles, to form the upper surface of the street. The paving of a street using bricks is a very labour-intensive activity. The work is moreover very tiring for the pavers. Another drawback of the use of bricks to make a street is that, in the case of rainfall or heavy load on the street, subsidence or displacement of the bricks occurs . This has an adverse aesthetic effect and forms a great hazard for road users in that the bricks point upward or holes occur in the street surface. In addition, the cost of repairing part of a street damaged in this manner is relatively high. In order to provide a solution to the above stated problem it is known in the prior art to make use of concrete elements which are arranged on the street to be formed, wherein they form the top surface of the street. A drawback of the use of such elements is that they are not very attractive from an aesthetic viewpoint. Another drawback is that the elements are not well connected to each other.
Use is usually made at the moment of a fixed connection between the different elements forming the street. A drawback hereof is that, when the street is loaded, for instance by a heavy truck or by intensive traffic, or by any subsidence of the ground as a consequence of rainfall, the elements will move to some extent relative to each other. Due to the rigid join between the elements the intervening connection breaks, whereby rainwater can pass easily between the elements and whereby the ground between the elements is flushed away, this resulting in a further subsidence of the elements. The rigid joins between the elements have the further drawback that they are not well able to withstand changing weather conditions .
The present invention has for its object to provide a solution to the above stated problems .
A first aspect of the present invention relates to an element system for forming a paving, comprising a first and a second concrete element, wherein during use a side surface of the first element is situated in the vicinity of a side surface of the second element such that an intermediate space is defined between the side surfaces and wherein the intermediate space is substantially filled with a joining agent such that, when the joining agent is cured, it forms a flexible join between the elements. An advantage of the present invention is that the join between the elements is flexible. Due to this flexible join the elements can move to some extent relative to each other.
This has the advantage that when the elements are unequally loaded no cracking of the join occurs. Another advantage is that the flexible join can withstand different types of weather conditions. It is also advantageous that the flexible join can be removed relatively easily when the elements are removed, for instance if maintenance is necessary on the cables or sewer pipes arranged in the street .
Concrete elements are understood to mean, among other things, slabs of concrete preferably of a length of 1-5 metres and a width of 1-5 metres. Furthermore, the slabs can also be round in form. When the elements form a street, at least one side surface of the one element will lie opposite the side surface of the other element. The joining agent can then be arranged between the elements by means of a device intended for this purpose such that the intermediate space between the elements is substantially filled.
In a recommended embodiment according to the present invention the side surfaces of the elements extend substantially parallel to each other. Thus is achieved that the intermediate spaces between the side surfaces of the elements are the same along the whole width or length of the slab, whereby a uniform join is obtained between the elements .
It is further recommended that the side surface of at least one of the elements is provided with at least one groove, and wherein the groove is substantially filled with the joining agent. An advantage of arranging a groove in the side surface of at least one of the elements is that a good connection is brought about between the element and the (cured) joining agent. Thus is achieved that a good join is obtained between the elements. It is recommended here that the groove extends in the length direction of the side surface. This also achieves an improved join between the elements. It is particularly recommended that at least one side surface of the first element and at least one side surface of the second element are provided with at least one groove. An extremely good mutual connection is obtained by arranging grooves in both side surfaces of the elements. In another embodiment according to the present invention all side surfaces of the element are provided with a groove. The arranging of a groove along all side surfaces of the elements has the advantage that on site the elements are easily connected to each other in order to form a street surface, without having to consider beforehand which side surfaces of the elements come to lie against each other. In an embodiment which is particularly recommended the grooves of the first and the second element lie substantially opposite each other. In this embodiment a very good connection between the elements is obtained, and the connection can withstand relatively great differences in load between elements joined to each other. It is particularly recommended here that the grooves are situated substantially in the middle of the side surface.
It is further recommended that the cross-section of the groove is substantially semicircular, triangular or quadrangular.
It is also recommended that the upper side and/or the underside of the side surfaces defining the intermediate spaces are provided with a faceted edge. An advantage of arranging a faceted edge is that, when the elements move to some extent relative to each other, the edges of the element do not break off.
It is further recommended that the elements forming the elements system are provided with a rail construction for a train or tram. It is also recommended that the upper side of the elements is provided with a design resembling paving stones. An advantage hereof is that the street surface has an aesthetically attractive appearance. It is particularly recommended here to provide the upper side of the element with a colouring substantially corresponding to the colour of paving stones .
A second aspect of the present invention relates to a concrete element, wherein one of the side surfaces is provided with at least one groove and wherein the groove extends in the length direction of the side surface.
It is particularly recommended here that the groove is situated substantially in the middle of the side surface. In an embodiment according to the present invention it is recommended that the cross-section of the groove has a substantially semicircular, triangular or quadrangular form.
It is further recommended that the element is provided with a rail construction for a train or a tram.
In an embodiment according to the present invention the upper side of the element is provided with a design resembling paving stones.
In another embodiment according to the present invention the upper side and/or underside of a side surface of the element is provided with a faceted edge.
A third aspect of the present invention relates to the use of an element system as described above or a concrete element as described above for the purpose of forming a paving.
Mentioned and other features of the element system and the concrete element according to the invention will be further elucidated hereinbelow on the basis of a number of exemplary embodiments, which are given only by way of example and without the invention thereby being deemed limited thereto. Reference is made herein to the accompanying drawings, in which:
Figure 1 shows a view of an element system according to an embodiment of the present invention. Figure 2 shows a cross-section along the line II of figure 1 of the connection between the elements.
Figure 3 shows an embodiment of a connection between two elements . Figure 4 shows a cross-section through an embodiment of another connection between the elements.
Figure 1 shows an element system 1 according to an embodiment of the present invention/ wherein a first element 2, which is provided with a design 3 resembling paving stones, is connected to a second element 4 which is also provided with a design 5 resembling paving stones. Elements 2,4 are mutually connected by means of a connection 6. This connection is formed by arranging in the intermediate space between elements 2, 4 a joining agent (such as a polyurethane polymer, such as for instance the pu-2-pack joint filler) . The join 6 is obtained after curing of the joining agent. In the embodiment shown in figure 1 a groove 14 is arranged in each of the side surfaces 7, 8 of elements 2, 4. These grooves 14 lie precisely opposite each other and are arranged in all side surfaces. Thus is achieved that after curing of the joining agent a join β is obtained having a round cross-section 9 in the middle. An advantage of such a join 6 is that relatively large forces can be absorbed by join 6. Another advantage is that when the elements have to be removed, the join 6 can be removed relatively easily. In addition, the first element 2 is provided with a channel 10 in which rail constructions for a train or a tram can be accommodated. Element 4 is further provided with an opening 11 for a drain. In order to prevent edges of elements 2, 4 breaking off when they are .relatively heavily loaded, the edges of elements 2, 4 are provided with a faceted edge 12, 13.
Figure 2 shows a detail section of the connection of figure 1 in the direction designated with II. As described above, side surfaces 7,8 of elements 2,4 are provided with a groove which extends in the length direction of side surface 7,8 and which is arranged substantially in the middle of the side surfaces. The grooves lie substantially opposite each other such that they form a so-called goblet connection 6. This achieves that the elements can withstand a relatively great load. Figure 2 further shows that the side surfaces of the elements are provided with a faceted edge 12, 13. The arranging of such a faceted edge 12, 13 prevents the edges of the elements breaking off when they are loaded.
Figure 3 shows a cross-section of a preferred embodiment of the present invention, wherein side surfaces 15, 16 are each provided with two grooves 17, 18 arranged in the length direction of side surface 15, 16 of the elements . The grooves of the two elements here also lie substantially opposite each other. A join is thus obtained between the elements which comprises two spherical parts 19, 20. A very good join between the elements is hereby obtained which can withstand a relatively great load. The edges of the side surfaces of the elements are further provided with faceted edges 21, 22. Figure 4 shows a cross-section of an embodiment of the present invention substantially corresponding to that of figure 2, although here the cross-section of groove 23 has a triangular shape.
