Due to the miniaturization of the control means and the image pickup device due to the technical progress, it is now possible to integrate control means and image pickup device in a control column which, in contrast to the control bridge, does not span the road but is located completely beside the road. With such a design of the control device as a control column can be compared to a control bridge save both manufacturing costs and construction costs and maintenance costs.

For the foundation of columns in the ground precast concrete parts according to the preamble of claim 1 are known from the prior art. For the roadside foundation of pillars, the frequently encountered topographies of embankments in the vicinity of the road up to 50 meters away from the road give rise to the problem of designing a precast concrete element for the foundation of a pillar in a topography-dependent manner. In particular, the object is to provide a precast concrete element for establishing a to be supplied with electric power control column, which is suitable both a foundation of the control column on a sloping from the road on a landfill slope of an embankment and at one of the street in one To enable terrain incision from rising slope of an embankment.

It is further an object to provide a control device with a control device to be supplied with electric power in the form of a control column and with a concrete skill, which allows a foundation of the control column both on a road to the road as well as on a road and sloping slope.

This object is achieved by a precast concrete part according to claim 1 and by a control device with a precast concrete part according to the invention and a control column according to claim 12. Advantageous developments are Subject of the dependent claims. Features and advantages of various embodiments are applicable to the other embodiment transferable or interchangeable, as far as this is technically possible and without contradiction.

In summary, the invention provides a prefabricated concrete element which is suitable for establishing a control column on a roadside slope and a mounting plate having at least one supply opening for a supply line of the control column and connected to the mounting plate foundation structure whose extension in a valley-side region of the precast concrete in facing away from the mounting plate direction is greater than in a mountain-side region of the precast concrete part.

Furthermore, the invention provides a control device with such a precast concrete part and a control column comprising an image recording device, which is attached to the precast concrete part, wherein a supply line of the control column is arranged in sections in the supply opening.

More particularly, the invention provides a single or multi-piece precast concrete element comprising at least one concrete-containing mounting plate having a mounting side and a mounting side opposite base side, and at least one concrete containing mono- or multi-part foundation structure extending from the base in one of Mounting side pioneering basic direction extends, and is characterized in that the mounting plate at least one, extending from the mounting side to the mounting side of the base side of the mounting plate extending first supply opening, at least one angularly to the mounting side extending valley side and at least one of the valley side opposite mountain side and the foundation structure has at least one valley-side foundation structure region and at least one mountain-side foundation structure region that is disjoint from the valley-side foundation structure region, wherein the mountain side foundation structure region is spaced further from the valley side than the valley-side foundation structure region and the valley-side extension of the valley-side foundation structure region in the base direction is greater than the mountain side extension of the mountain side foundation structure region in the base direction.

Whenever the text of this invention refers to a "side" of a component (precast concrete, control column), synonymous is meant the area provided by the side of that component. One side need not be flat, but may have a rough, undulating, or curved surface, as well as a plurality of distinguishable surface portions which are inclined no more than 90 ° from each other. A first side is angled with respect to a second side if its in-plane or out-of-plane surface normals or the averages of surface normals encompassed by the respective side point in different directions. A first side is considered to lie opposite it with respect to a second side when a first (inwardly or outwardly facing) surface normal of the first side pierces the second side or a second (inward or outward facing) surface normal of the second side pierces the first side ,

By the extension of a foundation structure area in the direction of the ground is meant, in particular, the distance that a plane parallel to the base side, in which the point farthest from the base side lies on the surface of the foundation structure area, is removed from the base side.

The basic direction is preferably perpendicular to the base side and thus forms a normal of the base side. Preferably, the base side is parallel to the mounting side. Preferably, the valley side is perpendicular to the mounting side. Preferably, the mountain side is parallel to the valley side. Preferably, the mounting plate has a to the valley side and the Mounting side each arranged at right angles and a front side opposite the rear side, which is preferably parallel to the front.

With the invention, a structurally very simple precast concrete part is provided, which is suitable for the roadside establishment of a picture recording device comprising a control column on the road from both sloping and rising slopes. Advantageously, the inventive design of the precast concrete according to the invention of the inclination direction of the slope - rising or falling - independently. Depending on the direction of inclination, the prefabricated concrete part for the establishment of the said control column can either be aligned with the side of the road from the slope with its side facing the street or in the case of sloping from the road slope with their mountain side facing the road.

The precast concrete according to the invention thus has despite (or better because of) their asymmetry foundational versatility, which lacks the conventional precast concrete: Advantageously, the introduction of a berm in an existing embankment can be avoided with the precast concrete according to the invention, as for the ground-level foundation of a control column a conventional precast concrete would be necessary.

With the first supply opening, the precast concrete part provides a shaft through which a supply line routed on the side for supplying the image recording device with electric current (eg a power cable) can be guided from the base side of the mounting plate through the mounting plate onto the mounting side of the mounting plate, which is intended for the arrangement of the control column. In particular, it is provided that the control column is mounted in the assembly-side alignment of the supply opening, specifically in such a way that it covers or closes the supply opening on the assembly side.

The precast concrete part may be formed in one or more parts. In particular, it may have a first part provided by the mounting plate and a second part provided by the foundation structure. The mounting plate and the foundation structure can thus be advantageously produced independently of each other in various manufacturing processes. You can each other via mutually corresponding positive locking elements to form a horizontal positive connection, which arises when the mounting plate is placed on the foundation structure, positively connected (for example, after the tongue and groove principle). Alternatively or cumulatively, a cohesive connection of the mounting plate to the foundation structure is possible by means of a joining means (eg mortar) introduced between the mounting plate and the foundation structure. Alternatively or cumulatively, a frictional connection of the mounting plate with the foundation structure by means of corresponding, mutually corresponding adhesion elements (for example, according to the nut-screwdriver principle) is possible.

Also, the foundation structure may be formed in one or more parts, wherein all parts of the foundation structure are connected to the base side of the mounting plate. For example, the foundation structure may comprise two or three wall-containing concrete elements spaced from each other on the base side.

In an advantageous development, the precast concrete part according to the invention has, in addition to the first supply opening, at least one second supply opening extending from the mounting side to the base side of the mounting plate. This second supply port may alternatively be the first supply port for the implementation of said supply line are used. Due to the valley-to-mountain asymmetry of the precast concrete part, a second supply port introduces the possibility of a different chirality in the arrangement of the control column on the mounting plate than can be provided by the first supply port. The advantage of various possible arrangements of the resulting control device is particularly useful if, despite the changing depending on the inclination direction of the slope orientation of the valley side of the precast concrete to or away from the road the control column with respect to the road on the mounting surface of the mounting plate should always occupy the same position.

In addition, the first supply opening may have a first valley side distance to the valley side and the second supply opening may have a second valley side distance to the valley side that is greater than the first valley side distance. Thus, with respect to the case in which the first and the second Talseitenabstand are equal, also introduced with respect to the arrangement of the control column on the mounting plate asymmetry, which corresponds to the asymmetry of the foundation structure. Thus, the bivalent arrangement chirality of the precast concrete is extended from the foundation structure to the mounting plate, which provides an additional degree of freedom in the arrangement of the control column on the mounting plate.

The same applies to an alternative or cumulative arrangement requirement for the first and second supply openings, according to which the mounting plate has at least one angled to the valley side and angled to the mounting side front and at least one front side opposite the rear, the first supply opening to the front has a first front side distance and to the rear side has a first rear side clearance greater than the first front side clearance and the second service port toward the front side has a second front side clearance and has a second rear side clearance to the rear side smaller than the second front side clearance, the first rear side clearance and the second rear side clearance Front side distances are each smaller than the opening distance between the first supply port and the second supply port.

Particularly preferably, the sum of the first front-side distance and the second rear-side distance is smaller than the opening distance between the first supply opening and the second supply opening. Thus, a division of the mounting surface of the mounting side is achieved in two disjoint mounting surface areas, of which a first mounting surface area - in particular a first half of the mounting side - the first supply opening and the first fastening means, and a second mounting surface area - in particular a second half of the mounting side - the second Supply opening and the second fastening means. This is advantageous that one mounting surface area, which is not used for the attachment of the control column, for other purposes, in particular for those of the establishment, maintenance and repair, the control column available.

Particularly preferably, the mounting plate is rectangular and has side lengths that are in the relationship of equal to or greater than 3 to 2, in particular equal to or greater than 2 to 1, the side lengths of the valley and mountainside are greater than the side lengths of vertical front and back of the mounting plate.

In particular, the mounting plate may have at least one first fastening means arrangement associated with the first supply opening. This first attachment means serves to fasten the control column in the vicinity of or directly in the assembly-side alignment of the first supply opening on the mounting plate. Not to Attachment of the control column provided fastening means of the precast concrete part are not fastening means of the first fastener assembly.

Preferably, such a precast concrete part also has at least one second supply opening extending from the mounting side to the base side of the mounting plate and spaced from the first supply opening by an opening distance and at least one second fastening means arrangement associated with the second supply opening. This second fastener assembly is used for alternative attachment of the control column in the vicinity of or directly in the assembly side alignment of the second supply opening on the mounting plate, in the event that the control column of the control device is to give a different chirality than that by attaching the control column to the mounting plate would be provided by means of the first fastener arrangement.

In particular, the first fastening means arrangement has at least two first fastening means embedded on the mounting side in the mounting plate and mutually having a first fastening spacing, and at least two second fastening means surrounding the second supply opening are embedded in the mounting panel and mutually connected to one another Attachment spaced having second attachment means, wherein the first attachment distance and the second attachment distance are each smaller than the opening distance between the first supply port and the two supply port.

With this feature, a division of the mounting surface of the mounting side is achieved in two disjoint mounting surface areas, of which a first mounting surface area - in particular a first half of the mounting side - the first supply opening and the first fastening means, and a second mounting surface area - in particular a second half of the mounting side - having the second supply opening and the second attachment means. This is advantageous that one mounting surface area, which is not used for the attachment of the control column, for other purposes, in particular for those of the establishment, maintenance and repair, the control column available.

For the inventive design of the foundation structure, there are numerous variants, which can be provided depending on the material, size and area of application of the precast concrete part, advantageous.

Thus, the foundation structure may have the shape of a with respect to one of its axes of symmetry on one of the base side facing, in particular open, end cut at a first angle and facing away from the base side open end at a different from the first angle second angle hollow body. At the first end of the hollow body may be closed or also open. Preferably, the first angle is right-angled and the second angle is not right-angled. For example, the second angle is in the range of 80 ° to 50, which is adapted to corresponding slopes of 10 ° to 40 °.

Due to the shortening or alignment of the opposing end faces of the first and second end of the hollow body at different angles, the hollow body has on a first side a greater extent from the first to the second end face than on a second side opposite the first side.

Of course, such a foundation structure according to the invention is arranged oriented on the base side of the mounting plate such that the greater extent of the foundation structure faces the valley side and the smaller extent of the mountain side. For example, the first side of the foundation structure is located together with the valley side the mounting plate in a common plane and / or the second side of the foundation structure together with the mountain side of the mounting plate in a common plane.

For example, on the one hand, such a foundation structure, the shape of a relative to its longitudinal axis on one of the base side facing end at a first angle, in particular at right angles, cut to end and the base side opposite end at a, different from the first angle, second angle, in particular not perpendicular, have cut hollow cylinder. In summary, this foundation structure is an obliquely cut hollow cylinder.

For example, on the other hand, such a foundation structure, the shape of one with respect to one of its major axes on one of the base side facing, in particular open, end at a first angle, in particular at right angles, cut to end and facing away from the base end at one, different from the first angle, second Angle, in particular not rectangular, have cut hollow cuboid. In summary, this foundation structure is an obliquely cut hollow cuboid.

• So kann die Gründungsstruktur einen ersten keilförmigen Gründungsstrukturteil und wenigstens einen, von dem ersten keilförmigen Gründungsstrukturteil beabstandeten, zweiten keilförmigen Gründungsstrukturteil aufweisen, wobei der erste keilförmige Gründungsstrukturteil derart an der Grundseite der Montageplatte angeordnet ist, dass die Erstreckung des ersten keilförmigen Gründungsstrukturteils in Grundrichtung in Richtung der Bergseite abnimmt, und der zweite keilförmige Gründungsstrukturteil derart an der Grundseite der Montageplatte angeordnet ist, dass die Erstreckung des zweiten keilförmigen Gründungsstrukturteils in Grundrichtung in Richtung der Bergseite abnimmt.

Compared to these examples for a one-piece training, various multi-part configurations of the foundation structure are conceivable:

• Thus, the foundation structure may comprise a first wedge-shaped foundation structure part and at least one second wedge-shaped foundation structure part spaced from the first wedge-shaped foundation structure part, the first wedge-shaped foundation structure part being arranged on the base side of the mounting plate such that the extension of the first wedge-shaped foundation structure part in the direction of the base Bergseite decreases, and the second wedge-shaped foundation structure part is arranged on the base side of the mounting plate such that the extension of the second wedge-shaped foundation structure part decreases in the direction of the mountain side in the direction of the bottom.

For example, such a foundation structure is provided by two or more wedge-shaped wall members disposed on the base side of the mounting plate so as to taper in the valley-to-mountain-side direction. Insofar as such a foundation structure no longer has constituent structural parts as the first and the second constituent structural part, it is in several parts; if it has at least one additional foundation structure part which connects the first foundation structure part to the second foundation structure part, then it is in one piece.

Alternatively or cumulatively, the foundation structure may comprise a first, valley-side wall element and at least one second, mountain-side wall element spaced from the first wall element, wherein a first inner side of the first, valley-side wall element facing the second, mountain-side wall element has a first edge distance to the valley side first, the second side facing the valley side wall elements facing the second, mountain-side wall element to the valley side has a second edge distance which is greater than the first edge distance, the first wall element starting from the base side has a first extension in the base direction, and the second wall element starting from the base side a second extent in the base direction, which is smaller than the first extent.

The term of the edge distance to the valley side is to be understood in this context that means the smallest distance of the respective inner side to a plane in which lies the valley side. For example, if the first outer side of the first, valley-side wall element lying opposite the first inner side lies on a common plane with the valley side of the mounting plate, then the edge distance is identical to the wall thickness of the first, valley-side wall element.

In the case of the cumulative provision of two wedge-shaped foundation structure parts as well as a valley-side and a mountain-side wall element through the foundation structure, these components may be arranged and interconnected such that the two wedge-shaped foundation structure parts together with the valley-side and the mountain-side wall element form the above-mentioned obliquely cut-off hollow cuboid forms a one-piece foundation structure.

The asymmetrical design of the foundation structure according to the invention requires, without further measures, that the center of gravity of the precast concrete part is located closer to the valley side (more precisely, to a plane that includes the valley side) than to the mountain side (at a level that includes the mountain side). This can result in the founding of the precast concrete part on a slope to an undesirable down-side tilting or displacement of the precast concrete, which is detrimental to a reliable fixation of the precast concrete on a slope.

To avoid this, measures are provided in the development of the invention, with which the center of gravity of the precast concrete part in mountain-side direction (more precisely: in the direction of a plane which includes the mountainside) can be moved.

• Vorzugsweise sind die Materialkompositionen, die äußeren Formen und/ oder die inneren Strukturen des talseitigen und des bergseitigen Teilbereichs derart ausgebildet, dass der Schwerpunkt des Betonfertigteils gegenüber dem Fall, in dem die Materialkomposition, die äußere Form und die innere Struktur des talseitigen Teilbereiches und des bergseitigen Teilbereiches gleich sind, in bergseitiger Richtung verschoben ist.

In this sense, it is proposed that the precast concrete part has a valley-side partial area and a mountain-side partial area which is disjoint from the valley-side partial area, wherein the valley-side partial area has a material composition different from the mountain-side partial area and / or a different shape structure from the mountain-side partial area:

• Preferably, the material compositions, the outer shapes and / or the inner structures of the valley side and the mountain side portion are formed such that the center of gravity of the precast concrete part over the case where the material composition, the outer shape and the inner structure of the valley-side portion and the mountain side Subarea are the same, is shifted in a mountainous direction.

The extensions of the valley-side foundation structure area and the mountain-side foundation structure area in the foundation direction, which are different according to the invention, are of course excluded from the equality of the outer shape of the valley-side partial area and the mountain-side partial area. An equality of the outer shape of the valley-side portion and the mountain-side portion is according to the invention only in their extensions perpendicular to the direction of formation - in particular parallel to the base side, when the foundation direction is perpendicular to the base - possible.

Particularly preferably, the material compositions, the outer shapes and / or the inner structures of the downhill and the downhill portion are formed such that the center of gravity of the precast concrete part lies on a normal to the mounting side straight lines through the center of gravity of the mounting side and / or the base side of the mounting plate goes. In order for the precast concrete part would be balanced in the middle, in the sense that, for example, when resting the surface center of the base page on a Balancierspitze the mounting side and / or the base side horizontally.

For example, the foundation structure is formed of a first valley-side foundation structure area and a second mountain-side foundation structure area, the valley-side foundation structure area having a material composition, outer shape, and / or inner structure different from the mountain-side foundation structure area, and wherein the material compositions, exterior shapes, and / or interior structures of the valley-side and the mountain-side foundation structure area are formed such that the center of gravity of the precast concrete part is on a mounting side normal line, which passes through the center of gravity of the mounting side and / or the base side of the mounting plate.

For example, at least the mountain-side foundation structure region may comprise a second metallic material in addition to concrete, wherein the amount of metallic material in the mountain-side foundation structure region is such that the center of gravity of the precast concrete element is on a straight line normal to the assembly side through the center of gravity of the assembly side and / or the base side of the mounting plate goes.

In addition, the mountain-side foundation structure region may have a mountain-side dimension in a direction other than its extension greater than the corresponding valley-side dimension of the valley-side foundation structure region, with the mountain-side extent being such that the center of gravity of the precast concrete element is on a straight line normal to the assembly side which passes through the center of gravity of the mounting side and / or the base side of the mounting plate.

Furthermore, at least the valley-side foundation structure region may have one or more cavities, the size of the cavity or cavities being such that the center of gravity of the precast concrete element lies on a straight line normal to the assembly side, through the center of gravity of the mounting side and / or the base side Mounting plate goes.

Preferably, two of these different or all of these options are used cumulatively, and are coordinated such that the center of gravity of the precast concrete part lies on a normal to the mounting side line that goes through the centroid of the mounting side and / or the base side of the mounting plate.

Alternatively, the mounting plate is formed of a first, valley-side mounting plate area and a second, mountain-side mounting plate area, wherein the valley-side mounting plate area has a different material composition, outer shape and / or inner structure from the mountain side mounting plate area and wherein the material compositions, the outer shape and / or the Inner structure of the valley-side and the mountain-side mounting plate area are formed such that the center of gravity of the precast concrete part lies on a straight line to the mounting side, passing through the centroid of the mounting side and / or the base side of the mounting plate.

For example, in the second uphill region, the mounting plate may include a second metallic material in addition to concrete.

For example, the mounting plate may have a smaller extension (height) in the base direction than in the second, mountain-side region in the first, valley-side mounting plate region.

For example, the mounting plate in the first, talseifigen mounting plate area may have one or more cavities.

Preferably, two of these different or all of these options are used cumulatively, and are coordinated such that the center of gravity of the precast concrete part lies on a normal to the mounting side line that goes through the centroid of the mounting side and / or the base side of the mounting plate.

Further, both the foundation structure of a first valley-side foundation structure area and a second mountain-side foundation structure area and the mounting plate may be formed of a first valley-side mounting plate area and a second mountain-side mounting plate area, wherein both the valley-side foundation structure area has a material composition different from the mountain-side foundation structure area and / or a shape structure different from the mountain side foundation structure region, and the valley side mounting plate region has a different material composition from the mountain side mounting plate region and / or a different shape from the mountain side mounting plate region and wherein the material compositions and / or the molding structures of both the valley side and the mountain side foundation structure regions and the valley-side and the mountain-side mounting plate portion are formed such that the center of gravity of the precast concrete part lies on a normal to the mounting side straight line passing through the centroid of the mounting side and / or the base side of the mounting plate.

Thus, the aforementioned measures on the foundation structure and the mounting plate can be used cumulatively and coordinated so that the center of gravity of the precast concrete part is on a normal to the mounting side straights, which goes through the centroid of the mounting side and / or the base side of the mounting plate.

Of the precast concrete part of the first embodiment, the precast concrete part 41 of this seventh embodiment initially differs in that its foundation structure 20 is not in one piece, but in several parts - namely three parts - is formed, that on the one hand the valley-side wall element 26 and the mountain-side wall element 27 missing The first embodiment, which connects the front-side foundation structure part 23 to the rear-side foundation structure part, and, secondly, in that an intermediate foundation structure part 25 is attached to the base side G of the mounting plate 10 in a central position between the front-side foundation structure part 23 and the backside foundation structure part 24.

In addition, the foundation structure parts 23, 24, 25 not only have a wedge shape in the base direction but also in the longitudinal direction: In the width direction from the valley side T to the mountain side B, the extension of the foundation structure parts 23, 24 and 25 in the base direction (height) of 1 meter decreases to 0.25 meters and increases the extension of the foundation structure parts 23, 24 and 25 in the longitudinal direction (thickness) of 0.25 meters by 0.50 meters for the outer front and rear foundation structure parts 23 and 24 and of 0.25 meters 0.75 meters for the intermediate foundation structure part 25. On the valley side remain between the intermediate foundation structure part 25 and the outer foundation structure parts 23 and 24 respectively gaps of 112.5 centimeters, mountain side of 62.5 centimeters.

On the valley side, the three foundation structure parts 23, 24 and 25 each have a chamfered end face F over a width (in the valley-to-mountain-side direction) of 25 cm.

The three foundation structure parts 23, 24 and 25 each have a valley-side foundation structure area 21 for a first half of their width and a mountain-side foundation structure area 22 for a second half of their width. The valley-side foundation structure region 21 has, as in the cross-sectional view of FIG Fig. 7b schematically and exemplified for the intermediate foundation structure part 25, a plurality of cavities 29, which serve to reduce the weight of the valley-side foundation structure region 21 and thus to move the center of gravity of the precast concrete part 41 in the mountain-side direction. With the appropriate dimensioning and arrangement of the cavities 29, it is even possible to bring the center of gravity of the precast unit 41 on a normal to the mounting side M straight line, which goes through the centroid of the mounting side of the mounting plate - the bottom piercing point of this line is Fig. 7a marked with the cross-shaped symbol 16 - and thus to balance the precast concrete part.

In order to prevent the void content from taking more than 50% of the volume prescribed by the outer dimensions of the valley side foundation structure region 21 which might affect the stability of the valley side foundation structure region 21, two measures for increasing the weight of the mountain side foundation structure region 22 are in this seventh Embodiment provided: A mountain-side residual height of the foundation structure part 23, 24 and 25 (here 25 centimeters) and a wall thickness that is greater than the mountain-side foundation structure area 22 is greater than in the valley-side foundation structure area 21st

Rough estimates for the present case, the void fraction in the valley-side foundation structure portions 21 of the foundation structure part 23, 24 and 25 for the balancing of the precast concrete part 41 must be about 30 to 35%. In this case 10 cavities may be introduced into the valley-side half of the mounting plate.
