Description

【Technical field】
[0001]
The present invention relates to a stone that forms a paved surface. In the present invention, the pavement surface means all the ground covered with stones, but it is used in private fields, such as the formation of roads and squares, for example, by public works, It is related to the construction of roadways and terraces. And it does not exclude application to such a paved surface in a place covered with a roof.
[0002]
In a first example, the present invention relates to concrete stone. Either cast concrete stones or vibratory concrete stones, and more generally, stones made from other base materials may be applied.
[0003]
It is known that the pavement surface can be realized with natural stone such as cobblestone. Because of the irregular shape of cobbles, it is more difficult to line up than regular shaped stones, and as a result, the pavement person must have the skill to line up the cobbles in good order.
[0004]
It is also known that the pavement can be made of classic concrete stone, more specifically burnt bricks known to have a regular shape. The advantage of burnt bricks is that the pavement surface can be easily realized by simply placing them next to each other and in contact with each other on a simply prepared lower layer, such as a flat sand base. It is.
[0005]
However, the disadvantage is that a pavement surface with a natural appearance cannot be realized using such burnt bricks.
[0006]
According to the first aspect, the present invention allows the upper side to show an irregular or specially shaped appearance with an irregular shape, eg imitation of natural stone, and the other is regular. It is intended for stones that can be arranged as easily as burnt bricks with a typical shape, and thus eliminate the need for experienced and special humans.
[0007]
For this purpose, the invention is characterized in that it has an irregular or specially shaped upper part on one side and provides a means for lining up such stones together with other similar stones in the usual way. It relates to a stone that forms a pavement surface.
[0008]
Stone laying is determined by the above means and not by an irregular or specially shaped upper part. And because of the unique design of those means, the stones can be pressed against each other in a simple manner as before.
[0009]
The means is a portion that defines a regular contour, and is preferably constituted by a contact portion that is lower than the upper side surface of the stone and is located on the side surface of the stone.
[0010]
As a result, the stones can be easily placed with the contact portions in contact with each other while being arranged. As a result, precise mutual placement of stones can always be achieved without requiring any special skills.
[0011]
In practice, when viewed from above, the upper contour of the irregular shape is located within the range of the regular contour. In this way, the stones can always be pressed against each other in the regular shape at the bottom in the usual way without being disturbed by the irregular design at the top.
[0012]
In a most preferred embodiment, said means are located under said irregularly shaped upper part and more particularly consist of a regularly shaped part realized in the basic shape. .
[0013]
As a result of the above, when placing this stone against similar stones, a joint is created adjacent to the top of these stones that is suitable to be filled with a filler such as sand or filling mortar. In such a method, it is preferable to have the irregularly shaped portion that is receded laterally with respect to the upper portion, more specifically, the portion located below the upper portion. As a result, the lower part having a regular shape is hidden from view by a joint filled with filler. In fact, the stones are in a fixed position where they are pressed against each other, resulting in the impression that the stones are laid out in a relaxed manner, even though mutual movement is eliminated.
[0014]
The retracted portion preferably has an undercut. This is accompanied by the advantage that the filler supplied to the joint is well maintained.
[0015]
More particularly, it is desirable that the undercut be realized so that when such stones are lined up with similar stones, so to speak, an inverted wedge shaped joint opening is created. As a result, fillers such as sand supplied thereto and hardened filling mortar are particularly well retained in this joint opening.
[0016]
In a particular embodiment, the stone is provided on its side with portions that ensure a water passage when several of such stones are pressed against each other side by side. That part, when viewed from above, starts from below the irregularly shaped part and / or from the lower end of the retracted part. This part is below the top surface of the stone, and it means that the part above it is filled with sand, so the part that should guarantee the passage of water is always hidden from view.
[0017]
And it is advantageous that the part that guarantees the passage of water does not form a factor that disturbs the appearance of the surface of the resulting paved surface, especially if it extends to the visible upper surface of the stone. Accompanying the point.
[0018]
In an actual embodiment, the part forming the passage for water is constituted by one or more grooves formed on one or more sides of the foundation.
[0019]
The use of receding parts with connections that can be filled with sand or filling mortar can also be advantageous in combination with stone embodiments that do not have an irregular and specially shaped upper part I will point out that.
[0020]
According to a second aspect of the invention, the invention is similar to an upper part having such a contour along the side of the upper part, as opposed to a contour formed by the part located below it. When stones are placed side by side, the joints are composed of receding parts that are formed to be created adjacent to the upper parts of those stones that are suitable for filling with filler. It is also related to the stone that forms the accompanying pavement.
[0021]
Here, the upper portion may have a regular shape.
[0022]
This has the advantage that, on the one hand, stones can be pressed against each other and on the other hand can be created on the upper surface where a joint filled with sand or other filler is visible.
[0023]
Another advantage is that at least the upper surface can create a joint filled with hardened mortar like cement between the stones arranged next to each other, resulting in a complete It is possible to realize a dense pavement surface.
[0024]
This is particularly useful when building a terrace. When concrete stones are lined up against each other loosely, sand leakage between the stones, which is often the case, is completely avoided.
[0025]
This is also useful for applications where water penetration must be limited and avoided and / or where it is desired to minimize the risk of weed growth between stones.
[0026]
In this case, it is also clear that the receding part is preferably realized, and when laying this stone together with a similar stone, a so-called inverted wedge shaped opening is created.
[0027]
The application of the part that increases the passage of water between the stones, starting from the bottom layer and always hidden from view with respect to the pavement surface, as mentioned above, the upper part does not necessarily have a special or irregular shape. This may not be the case in the combination of stone embodiments.
[0028]
According to the 3rd side surface of this invention, it is related with the stone which forms a pavement surface as follows. It includes an upper part in which a receding part with a contour surrounding the upper part is formed relative to the contour formed by the part located below, the stone Are arranged side by side with a part on the side where water passages are formed, said part starting from below the upper part in order to spread from the top down to the bottom of the stone Has characteristics.
[0029]
In general, it is preferred that the irregularly shaped portion and / or the receding portion extend at a height and depth of at least 0.5 cm, more preferably at least 1 cm, so that even if Even if it is composed of loose sand, the filled joint is safely guaranteed.
[0030]
From the foregoing it is clear that the present invention is particularly useful in the case of concrete stones.
[0031]
For the purpose of better illustrating the features of the present invention, some preferred embodiments will now be described with reference to the drawings, by way of example, without any limiting features.
[0032]
As represented in FIGS. 1 to 5, the present invention forms a paved surface 2 with an irregular or specially shaped upper part 3 on one side and another similar stone 1 on the other side in the usual manner. It relates to a stone 1 provided with means 4 that allow it to be arranged together.
[0033]
The means 4 is constituted by a contact piece 5 located at a position lower than the upper side 7 of the stone 1 and located on the side 6 of the stone 1. These contact parts 5 thereby determine a regular contour 8 shown in FIG.
[0034]
These contact parts 5 are located under the upper part 3 and consist of the side walls of a regularly shaped lower part 9 which realizes the shape of the foundation.
[0035]
From the plan view, it is clear from FIG. 3 that the contour of the upper portion 3 is located in the contour 8.
[0036]
In this way, the upper part 3 has a receding part 10 relative to the lower part 9.
[0037]
Similar to FIG. 5, as is apparent from FIGS. 1 and 2, the retracted portion 10 is preferably implemented as an undercut. And it is formed by narrowing the side 11 downward. As a result, as can be seen in FIG. 5, when similar stones 1 are arranged together, a so-called wedge-shaped joint opening 12 is created.
[0038]
Furthermore, the stone 1 has a portion 13 that guarantees a water passage 14 on its side, and more particularly on one or more sides, as shown in FIG. 5, when several of the stones 1 are laid side by side against each other. It is preferable to provide.
[0039]
The part 13 then starts downwards under the irregularly shaped upper part 3 and / or from the lower side 15 of the receding part 10.
[0040]
In this case, the portion 13 is formed by a vertical groove provided in each lateral surface 6.
[0041]
The height H, which is referred to as the depth of the joint opening 12, extending through the upper part 3 and / or the receding part 10, is preferably at least 0.5 cm, more preferably at least 1 cm.
[0042]
The use of the stone 1 and more particularly the way in which the pavement surface 2 is formed can be achieved from the above description simply as from FIGS. However, for the sake of clarity, a brief description will be given below.
[0043]
As represented in FIG. 5, the stone 1 is provided on a flat sand base 16 by way of example, as is also traditionally practiced in classic burnt bricks. Here, they are simply positioned by pressing the contact portions 5 together.
[0044]
The upper part 3 is always located in the contour 8 of the lower part 9. The irregular shape of the upper part 3 is not a hindrance to arranging the stones 1 in a normal manner.
[0045]
Here, a relatively deep junction opening 12 is created. And, as mentioned above, it should preferably have an inverted wedge shape or, more precisely, a dovetail shape.
[0046]
As a result of the relatively deep joint openings 12, sand 17 hardly leaks from the joint openings 12 after they are filled with sand 17 or the like.
[0047]
As a result, the effect is obtained that the lower part 9 remains hidden from view in a guaranteed manner.
[0048]
Due to the wedge shape, the sand 17 is also better retained in the joint opening 12.
[0049]
The part 13 described above also starts at a relatively large distance below the top side 7 of the stone 1, i.e. a distance corresponding to the height H, so that sand 17 etc. will always be present on them.
[0050]
As a result, the effect that the portion 13 does not disturb the appearance of the upper surface when the joint opening 12 is filled in a normal manner is obtained.
[0051]
Obviously, the present invention is not limited to a particular stone design. By way of example, many variants of such a stone 1 are represented in FIGS.
[0052]
In FIGS. 6 to 8, a curved, clasp-shaped stone 1 is represented.
[0053]
In FIGS. 9 to 11, the lower part 9 has a relatively low height and the retracted part 10 represents a variant realized as a recessed part extending around the periphery.
[0054]
12 to 13, the upper portion 3 having an irregular shape at the upper end has a straight side surface, but has an inclined side surface 11 in which an undercut is formed at a lower position to some extent.
[0055]
14 and 15 show other variants. The upper part 3 of the foundation is connected to the lower part 9 of the foundation. This is the opposite of the embodiment of FIGS. Thereby, the transition between the upper part 3 and the lower part 9 is stepped.
[0056]
FIG. 16 shows that the contact part 5 does not necessarily have to be composed of a massive foundation, but may be realized as a locally present element, in this case as a corner member at the bottom of the stone 1. .
[0057]
Finally, the use of the receding part 10 and / or the use of the part 13 starting with the lower layer is not irregularly shaped, but also has a straight side or a regular-shaped contour side and is made regularly. It should be noted that this is possible with a combination of stones 1 with an upper portion.
[0058]
The invention is in no way limited to the embodiments described by way of example and represented in the figures. Conversely, it is possible to implement such stones in different shapes and dimensions without departing from the scope of the present invention.
