Description

The invention relates to wall elements for creating a wall, walls with corresponding wall elements and methods for building a corresponding wall. Preferably it is about embankment walls, garden walls, soundproof walls and other walls in the outdoor area.

Very many different systems are known from the prior art, which are designed to create such walls. A solution that has a high stability, is from the published patent application DE 3033650 A1 known. In this publication, it is proposed to build a wall of heavy, stacked, box-shaped elements so that the wall is upwards - similar to a pyramid - narrower. In this way, for example, create a sound barrier from the box-shaped elements. The depth of the box-shaped elements decreases with increasing height of the wall.

From the European patent application EP 322667 A1 For example, a system is known that includes hollow components from which walls can be made. The hollow components have a cavity open at the top and at the bottom, which is subdivided into two chambers by at least one partition which runs from top to bottom. The components are stacked and stacked at least partially filled with earth. Only a part of the chambers is located on the wall outside. At least a part of the not on the wall outside chambers are filled with concrete.

From the Swiss patent application CH 612238 A5 For example, a system is known which comprises dual-chamber components from which walls can be made. However, these two-chamber components are not flexible.

From the French patent FR959948 A , which dates from 1949, and discloses a wall element according to the preamble of claim 1, a very early form of wall elements is known, which are designed so that each two wall elements can be joined together with two U-shaped brackets. Each wall element comprises corresponding blind holes which extend perpendicularly into the material of the wall elements and at the point of approach of the blind bore each comprise an open cavity for sunk receiving the brackets.

From the French patent FR549299 A , which dates from 1922, is a very early form of wall elements, which are designed to have an open intermediate area suitable for the circulation of air. Again, two wall elements are joined together with two brackets. The brackets have a dovetail-like, relatively chunky shape.

An elastic splinter protection wall, which is built up from form elements, can the German Auslegeschrift DE 1062419 be removed.

There are several other systems and modules that are used to create walls, depending on the situation and the specification. To give these walls the required stability, they are either very massive and heavy designed, or they are anchored with anchors in the soil or rock to be intercepted or supported.

The material and work effort is often very large, especially since in addition to the static requirements and aesthetic aspects can play a role.

It is therefore the task of a new, modular system to provide, which makes it possible to create very stable and visually appealing walls. It should be possible to work with a few parts to keep the cost of manufacturing and storage small.

According to the invention, a wall element is provided according to claim 1, which is designed especially for creating walls. The wall element comprises two basic elements and at least one connecting element. Each of the basic elements comprises a lateral plate having an outer surface and an inner surface. In addition, at least one transverse web is arranged in the region of the inner surface, which extends substantially perpendicular to the surface of the lateral plate. In the preassembled state, i. before a filling material is introduced into interiors between the primitives, the two primitives are arranged such that the surface of the first lateral plate is parallel to the surface of the second lateral plate and that the transverse web of the first lateral plate is aligned with the transverse web of the second lateral plate. The mentioned connecting element serves to define the distance of the two basic elements, to connect the two basic elements together and to lock together in order to give them stability before and during filling.

According to the invention, each transverse web has a vertical end surface with a receiving groove which extends over the entire height of the vertical end surface. This receiving groove opens on the top of the base member in a surface and on the underside of the base member in a lower surface, and it has an L-shaped, continuous horizontal cross-section from the surface to the lower surface. This special shape, orientation and arrangement of the receiving groove allows the insertion of the connecting element from the top or the bottom. In addition, the L-shaped, continuous horizontal cross-section allows tilting of the connecting element, wherein after tilting the two basic elements are locked relative to each other.

The connecting elements serve, as mentioned, also to specify the distance between the two basic elements. By using different sized fasteners, the inner width of the wall to be created, i. the mutual distance of the basic elements are specified.

The invention can be applied to walls, in particular slope protection walls, retaining walls, soundproof walls, garden walls, embankment walls, boundary walls and other walls. Since the walls of the invention are always filled with filler, is also spoken of a solid wall in the following.

The invention will be described below with reference to some embodiments. Before, two exemplary wall elements 10 based on Fig. 1A and Fig. 2A explained. These two wall elements 10 are basic elements that can be used in all embodiments.

Each of the wall elements 10 is specifically for creating a wall 100 (see, eg Fig. 6 ) designed. A wall element 10 is characterized in that it comprises two basic elements 11.1, 11.2 and at least one bow-shaped connecting element 20. Each of the basic elements 11.1, 11.2 comprises a lateral plate 12.1, 12.2 with an outer surface 13.1, 13.2, which is also referred to as a visible surface, and an inner surface 14.1, 14.2, which is directed inward and is therefore no longer visible in the assembled state. Furthermore, at least one transverse web 15.1, 15.2 per basic element 11.1, 11.2 is provided. The transverse web 15.1, 15.2 is arranged in the region of the inner surface 14.1, 14.2 and extends substantially perpendicular to the vertical surface F.1, F.2 of the lateral plate 12.1, 12.2. The said vertical surfaces F.1, F.2 are in Fig. 1A indicated by dashed lines. The lateral plate 12.1 biases the surface F.1 and the lateral plate 12.2 biases the surfaces F.2.

The vertical surfaces F.1, F.2 are referred to as vertical surfaces, since they are in the assembled state, i. at a wall 100, stand vertically in the room.

In the following, a distinction is made between the pre-assembled state and the final state. The pre-assembled state is the Condition during the creation of a wall 100. In the preassembled state, the continuous interiors 16.1 and / or 16.2, which arise between the primitives 11.1, 11.2, not yet filled with a filler (such as soil and / or stones and / or cement) ,

In the preassembled state, the two basic elements 11.1, 11.2 are arranged or positioned such that the vertical surface F.1 of the first lateral plate 12.1 is substantially parallel to the vertical surface F.2 of the second lateral plate 12.2 and that the transverse web 15.1 of the first lateral plate 12.1 is aligned to the crossbar 15.2 of the second lateral plate 12.2 stands. Under aligned arrangement of the transverse webs 15.1, 15.2, an arrangement is to be understood here, where the longitudinal axis LA.1 of the transverse web 15.1 runs parallel to the longitudinal axis LA.2 of the transverse web 15.2. If the two basic elements 11.1, 11.2 are ideally aligned with each other, the two vertical surfaces F.1 and F.2 are exactly parallel to one another and the aforementioned longitudinal axes LA.1, LA.2 of the transverse webs 15.1, 15.2 coincide exactly (ie LA.1 = LA.2), as in Fig. 1A shown by way of example.

It is preferably per wall element 10 at least one bow-shaped connecting element 20 is used to connect the two basic elements 11.1, 11.2 together. The embodiment in Fig. 1A has per base element 11.1, 11.2 only one crosspiece 15.1, 15.2 and only one bow-shaped connecting element 20, while the embodiment in Fig. 2A two transverse webs 15.1, 15.2 and also two bow-shaped connecting elements 20 per basic element 11.1, 11.2.

The ideal positioning of the basic element 11.1, 11.2 is in the FIGS. 1A and 2A to recognize by two different embodiments. In the embodiment according to Fig. 1A the wall element 10 in the preassembled state a double-T-shape (viewed in plan view) on. The double T-shape can also be considered and designated as H-shape. A highly simplified perspective view of the double-T shape of the wall element after Fig. 1A is in Fig. 1B indicated by thick dashes.

In the embodiment according to Fig. 2A the wall element 10 in the preassembled state a double-π-shape (viewed in plan view) on. The double π-shape can also be considered and designated as a ladder form. A highly simplified perspective view of the double π-shape of the wall element after Fig. 2A is in Fig. 2B indicated by thick dashes.

Based on FIGS. 1A and 2A now exemplary measures are made. The outer surface 13.1 of the first base element 11.1 and the outer surface 13.2 of the second base element 11.2 typically have a square or rectangular basic shape with the edge masses L1 x H1. The distance of the front edge of the outer surface 13.1 to the front edge of the outer surface 13.2 is designated T1. The distance T1 depends inter alia on how far the end surfaces 17 (see Fig. 1A and Fig. 4B ) of the transverse webs 15.1 and 15.2 are spaced from each other.

In all embodiments, the vertical end surfaces 17 have a receiving groove 40 which extends over the entire height H2 of the vertical end surface 17. It should be noted that under certain circumstances, the height H2 of the transverse webs may be smaller than the height H1. Preferably, however, in all embodiments, the height H2 = H1, to ensure the mold release (as described later).

In all embodiments, the receiving grooves 40 open on the upper side of the basic element 11.1, 11.2 in a surface O1 (see Fig. 3C ) and on the underside of the base element 11.1, 11.2 in a lower surface U1 (see Fig. 3C ) opens. In addition, the receiving grooves 40 always have an L-shaped, continuous horizontal cross-section which extends from the surface O1 to the lower surface U1.

The end faces 17 of the transverse webs 15.1 and 15.2 can lie flat against one another in one embodiment. In this case the web distance AS = 0. This mounting position gives the minimum distance T1, which is determined by the following mass T1 = 2 (DL + LS) + 0.

Depending on requirements, the distance AS between the transverse webs 15.1 and 15.2 and thus also the distance T1 can be increased as desired. In the FIGS. 4A and 4B a state is shown in which the distance AS is 50 mm, for example. The following table gives further details of exemplary embodiments: Preferred range [mm] Specific example [mm] Length L1 of the outer surface 200 - 1000 500 Height H1 of the outer surface 100 to 500 200 Distance T1 150 - 1000 500 Bar distance AS 0 - 700 200 Bridge length LS 50 - 300 150 wall thickness = T1 5000 *) Thickness of the lateral plate DL 20 - 200 55 *) The wall thickness in the foot area of the wall can be greater than above

In Fig. 5 is shown a front view (visible side) of a part of a wall 100, which is composed of a plurality of wall elements 10. Preferably, the wall elements 10 each have a circumferential chamfer or broken edge 18 in all embodiments.

Preferably, the wall elements 10 in all embodiments obliquely raised edges 19 (see, eg 3C and 3E ). By this measure, it is possible the wall elements 10 to be arranged side by side so that they result in a Polygonenzug or an approximate circular arc. If the wall elements 10 are arranged side by side in a straight row, results in a triangular cut-out 101 due to the obliquely raised edges 19 (see, eg Fig. 4B ) in the intermediate region between two adjacent wall elements 10.

In Fig. 6 is a perspective view of a portion of a wall 100 shown in the preassembled state. The wall 100 shown here comprises three rows of wall elements 100, which have been placed offset from one another here in order to achieve a toothing effect. But the wall elements 10 can also Without offset in rows and columns are placed on each other, since the required stability is finally by filling the continuous cavities 16.1, 16.2 results with filler 50. The filler 50, especially if gypsum or cement is used, connects the individual wall elements 10 firmly together. In Fig. 6 is exemplary and shown schematically on the bottom wall row that the continuous interior spaces 16.1, 16.2 can be filled with a flowable filler 50. The interior 16.2 was not completely filled with the filler 50 here.

Preferably, in all embodiments, a flowable filler 50 is used which hardens or becomes compact.

Preferably, in all embodiments, scraper elements (not shown in the drawings) are used which are inserted or inserted into the filler 50 to provide added stability to the wall 100. Particularly preferred as Monierstahlelemente are steel anchors, steel baskets, steel reinforcements, steel bars, or steel mats.

In all embodiments, the wall element 10 preferably comprises a recess or a type of cavity 32 (see FIG Fig. 6 ), so that after filling with filler 50, the two basic elements 11.1, 11.2 of the wall element 10 can not slip apart. Such a recess or cavity 32 is in Fig. 3E provided with the corresponding reference number. In Fig. 6 It can be seen how the filler 50 fills this return or this cavity 32. After curing of the filler 50, the corresponding basic elements 11.1, 11.2 can no longer be separated from each other. The use of such recesses or cavities 32 is optional, as by the locking of the base elements 11.1, 11.2 by the / the bow-shaped connecting elements 20 apart from moving the basic elements 11.1, 11.2 is prevented.

Preferably, in all embodiments, the bow-shaped connecting elements 20 are used for locking and the mentioned recesses or cavities 32 are used in order to ensure lasting stability.

The wall 100, which in Fig. 6 is shown, the wall thickness 30 has the same thickness as on the wall crown 31. In a wall 100, the wall elements 10 after Fig. 2A is constructed, there are two types of interiors 16.1, 16.2. The interior spaces 16.1 are inherent in the wall elements 10 Fig. 2A present, ie, each of these wall elements 10, which has a double-π-shape, laterally encloses an inner space 16.1. Between two adjacent wall elements 10 results in the preassembled state, a second interior 16.2, which is also referred to here as a gap. In the juxtaposition of wall elements 10 after Fig. 1A , each result only in spaces 16.2.

In all embodiments, the spaces 16.1 and 16.2 are completely continuous from top to bottom (i.e., in the vertical direction).

Preferably, in all embodiments, a material from the following group is used as a filler: stones, crushed stone, concrete, mortar, plastic, plastic concrete, asphalt, tar, or a mixture of two or more than two of said materials. As the filler, a sound absorbing filler, e.g. a special concrete can be used.

Since the spaces 16.1 and 16.2 are completely continuous from top to bottom, the filling 50 extends over the entire height of the wall 100 (if sufficient filler 50 is filled).

Preferably, the wall elements 10 are made in all embodiments of stone, concrete, plastic concrete, plastic or a mixture of two or more than two of said materials. Particularly preferred are wall elements which are cast from one or more of the materials mentioned. The wall elements 10 and the basic elements 11.1, 11.2 have a shape that can be easily produced by casting and demolding of the mold, ie the shape is designed deliberately demoldable. For this reason, the receiving groove 40 is continuous. Depending on the casting method and mold, which is used, the basic elements 11.1, 11.2 must have a horizontal cross-section, on the entire height H1 is identical, ie the basic elements 11.1, 11.2 must not taper or thicken in the vertical direction.

If the wall elements 10 are to be used for a soundproof wall, the wall elements 10 are preferably made of a sound-absorbing material. Particularly preferred is a (concrete) granules, which is pressed into the appropriate (Giess-) mold to create wall elements 10, the surface of which is open-pored or porous.

Fig. 7 shows a side view of an advantageous intermediate product 60, from which according to the invention, two basic elements 11.1, 11.2 can be made. The intermediate product 60 is preferably designed so that it can be produced en bloc (ie cast and demolded) in a casting process. After the material which has been poured into a corresponding casting mold is cured, the casting mold is opened and the intermediate product 60 is removed (demoulded). Fig. 7 shows a plan view of the intermediate product after removal from the mold. Now, the two basic elements 11.1, 11.2 separated by the lateral plates 13.1, 13.2 are separated by splitting, sawing or cutting. The interface is in Fig. 7 denoted by the reference XX.

Preferably, the two basic elements 11.1, 11.2 separated by a wedge-shaped element is hammered or pressed. The wedge effect results in fracture surfaces, which are referred to as broken surfaces in the various figures. Such a broken surface has a slightly irregular surface structure, which corresponds approximately to the structure of a natural stone. This results in a visually very appealing structure for the visible surface, which consists of the outer surfaces 13.1.

The intermediate product 60 is further distinguished by the fact that the two later outer surfaces are firmly connected to one another. The two basic elements 11.1, 11.2 form quasi a one-piece intermediate product 60. The transverse webs 15.1, 15.2 each have outwards. The basic elements 11.1, 11.2 can, as in Fig. 7 indicated, oblique edges 19 and / or bevels 18 have.

Both the intermediates 60, as well as the basic element 11.1, 11.2 include in all embodiments continuous receiving grooves 40 for receiving the connecting elements 20. Corresponding embodiments are in the FIGS. 1A, 2A . 3A - 3E . 4A-4B . 5 . 6 and 7 shown. The receiving grooves 40 are preferably provided on the transverse webs 15.1, 15.2 such that the bow-shaped connecting elements 20 can be completely inserted from above or below. The receiving grooves 40 have in plan view, ie in horizontal cross-section, an L-shape. This L-shape is in the enlarged section of the Fig. 7 particularly clearly visible. The L-shape is composed of a trunk 41 and a base 42 extending substantially perpendicular to the trunk 41. The trunk 41 has a clear width A1 in the horizontal cross section. The base 42 has a clear width A2 in the horizontal cross section. The width A2 is preferably somewhat larger than the width A1 in all embodiments, in order to allow a problem-free tilting of the bow-shaped connecting element 20. The width A1 is in all embodiments a few millimeters larger than the outer diameter of the bow-shaped connecting element 20th

In all embodiments, the connecting element 20 is preferably designed as a bow-shaped metal clip or plastic clip which has a U-shape, as in FIG Fig. 8 shown. It is therefore also referred to as a bow-shaped connecting element 20. The bow-shaped connecting element 20 has two substantially parallel legs 22 and a connecting web 21 which extends between the two legs 22.

According to the invention, the basic elements 11.1, 11.2 serve as shuttering elements for creating / erecting a wall 100, wherein these shuttering elements remain permanently in the wall 100. After the basic elements 11.1, 11.2 have been preassembled and the respective spacings AS between the basic elements 11.1, 11.2 set (fixed with one or more connecting elements 20) and locked, the continuous interior spaces 16.1, 16.2 are filled with the mentioned filler 50. The basic elements 11.1, 11.2 serve as shuttering in order to prevent the filler 50 from flowing away or leaking out. Together with the filler results from the basic elements 11.1, 11.2 a very stable wall 100, which may have a constant thickness or a pyramid-shaped decreasing thickness, if necessary. A wall 100 with a pyramidally decreasing thickness has in the foot area, ie on the wall foot 30 (see Fig. 6 ), the largest wall thickness and is statically particularly advantageous. Anchoring with ground anchors is no longer necessary in many cases.

The clip 20, ie the bow-shaped connecting element 20, can be fixed in all embodiments either by the filler 50 or by a separate securing element (eg a wedge).
