Description

Carriers for devices and signs for spanning streets and paths

The present invention relates to a device and / or sign carrier for use on wider motor vehicle or narrower shipping lanes with a support-free carrying length of approximately 10 m to approximately 50 m and more.

Device carriers of this type are particularly interesting for the installation of new toll monitoring devices which are intended to carry identification units for automatic toll billing. The advantage of such toll systems is the lack of any toll stations that interrupt the flow of traffic.

The task of the monitoring devices is automatic vehicle detection, which requires the arrangement of radio receivers or scanners in order to either receive an identification signal in the form of a radio signal from the passing vehicles or to automatically scan the passing vehicle and from the scan image the official registration number and thus the billing address or booking address. The latter method requires an absolutely precise and vibration-free alignment of the device and this at higher wind speeds and gusts of more than 100 km / h. Of course, the device carrier should also be usable for appropriate monitoring of smaller waterways. In addition to the inclusion of devices, signs or only signs should be able to be held by the device carrier in order to create the most universal possible application for the device carrier.

It is therefore an object of the invention to provide a torsionally rigid device carrier which can be used universally and which enables an absolutely exact, reproducible and vibration-free arrangement and alignment of devices and / or signs on roads and paths.

The object is achieved according to the invention by an equipment carrier with the features of claim 1. Advantageous developments of the invention are the subject of the dependent claims.

The invention provides for a lightweight construction based on foundations consisting of vertical girders and a horizontal girder bridge running between them. The overall construction is preferably made of rustproof or rustproof treated or coated steel tubes. Of course, the device carrier can be represented as a plurality of vertically supported and horizontally mounted carrier bridges, which is particularly advantageous when spanning multi-lane motorways, where the number of vertical carriers corresponds to the number of horizontal bridges + 1.

Each vertical beam is held on a foundation and consists of two vertical support struts arranged one behind the other in the street direction or parallel to the street direction, which are connected to each other by truss-like diagonal struts. The length of the foundation in the direction of travel preferably clearly exceeds the distance between the two braced vertical support struts, which is preferably between 0.5 and 1.5 m. The length of the foundation preferably corresponds to approximately twice the distance between the two braced vertical support struts. The two interconnected struts together form a vertical support that receives one end of a horizontal support bridge.

The horizontal girder bridge consists of four horizontal support struts running parallel to each other, which can be arranged in a rectangular or trapezoidal cross-sectional view. The horizontal or horizontal support struts are also connected to each other by truss-like diagonal struts, so that there is a very torsion-resistant beam-like truss structure with a rectangular or trapezoidal cross-section. The horizontal girder bridge is connected at both ends to a vertical girder. For this purpose, each end of a horizontal support strut is connected to fastening points of the vertical supports and in this case two horizontal support struts are preferably each attached directly to the vertical support struts of the vertical supports. The diameter of the vertical and horizontal support struts is preferably at least 1.5 times as large as the diameter of the diagonal struts connecting them, as a result of which a very light, yet connection-rigid construction is realized. For the same reason, the diameters of the vertical support struts of the vertical supports are preferably at least twice as large as the diameter of the horizontal support struts of the horizontal support bridge.

A walkable floor is preferably formed between the two lower horizontal support struts of the horizontal support bridge, which are located on the same vertical level, so as to allow access to the devices and / or signs held by the device carrier during ongoing traffic. Maintenance can be carried out in this way, without affecting current traffic. As an alternative or in addition, provision can be made for the devices to be movably guided on rails, so that the devices can be moved out of the area above the carriageways during maintenance and are therefore accessible from the side for maintenance. A mounting platform or assembly ladder or the like is then preferably arranged on the vertical supports in order to enable simple and easy maintenance, installation or repair of the device. After maintenance of the device, the device is then z. B. retracted into its operating position by a corresponding cable or drive mechanism, where it then preferably engages in its operating position in a defined manner by means of a latching device. This is necessary insofar as maximum demands are placed on the alignment of the devices, particularly when mounting scanners, so that even after repeated maintenance operations, the device must be reproducibly repositioned after it has been moved back into its operating position. For this purpose, spring elements and stops can also be provided in the device fastening, by means of which the device is pressed into an exactly defined position in its operating position, avoiding any tolerances or play.

The foundations for holding the vertical beams, each consisting of two vertical support struts, are preferably elongated, e.g. B. ellipsoid or oval, whereby the foundation in the transverse direction of the street takes up little space and can therefore be installed both in tight spaces without unduly affecting traffic. On the other hand, the foundation is significantly longer than the distance between the two vertical support struts, preferably at least twice as large as the distance between the two support struts. In this way, a high level of security of the entire construction against collision and / or wind pressure is ensured. In particular, the building regulations for collision safety of the foundations are taken into account in a simple manner. The foundations preferably protrude upwards from the ground by about 0.5 to 1.5 m, which results in greater collision safety.

The diagonal struts between the horizontal and vertical support struts are preferably inclined at an angle of 30 to 60 degrees or 120 to 150 degrees to the corresponding support struts, whereby on the one hand a very stable and on the other hand very light construction is realized, which due to its "airiness" offers only a low wind resistance, while at the same time offering torsional and vibration resistance. In addition to the diagonal struts, cross struts, e.g. B. be provided between the horizontal support struts. In addition, horizontal struts can be arranged as railings in the diagonal bracing area of superimposed horizontal support struts.

Preferably, the construction has fastening elements arranged in a defined manner, e.g. B. in the form of eyelets, tabs or the like, in this way the attachment of different elements such. B. ladders, assembly trolleys or the like.

It is also possible to run rail systems for movable bone carriers down to the lower end of the vertical beams, which would make walking through the construction superfluous for maintenance purposes and thus bring increased operational safety.

The vertical support struts are preferably subdivided below the horizontal support bridge by a mounting flange with a horizontal surface and a vertical axis, in order to facilitate the assembly of the support bridge on site. The mounting flange is preferably self-centering in a manner known per se. Each part of the vertical support strut lying above the mounting flange preferably has two lateral fastening flanges one above the other, to which the horizontal support struts which are at different levels are fastened.

The horizontal girder bridge can be made from several horizontally interconnected modules in order to be able to implement different lengths. So z. B. on a base bridge part with a length of about 12 m additional extension pieces with a length of 1.20 m are flanged. Preferably, many times smaller extensions for an exact adjustment of the length of the overall construction can be achieved if adapter pieces of different lengths can be fitted between the longitudinal ends of the horizontal support struts and the fastening flanges of the upper sections of the vertical support struts. If e.g. B. Adapter pieces of 48 and 24 cm in length are provided, all lengths from 12 m can be set precisely in a length grid of 24 cm. In addition, by using adapter pieces of different lengths on the two upper horizontal support struts and the two lower horizontal support struts, inclinations of the horizontal support bridge can be compensated for, which result from the fact that the horizontal support bridge is not installed exactly horizontally but with a slight cross slope, which is usually the The road's slope is adjusted. Thus, the use of the different long adapter pieces between the longitudinal ends of the horizontal support struts and the mounting flanges an exact adjustment of the length of the horizontal support bridge and its inclination. The provision of the mounting flanges with a vertical axis also facilitates the mounting of the horizontal support bridge, which is prefabricated with the upper sections of the vertical support struts and the adapter pieces before final assembly, so that now only four self-centering mounting flanges with a horizontal flange surface need to be attached on site. which allows an extremely fast assembly of the girder bridge.

The invention is described below, for example, using the schematic drawing. In this show:

FIG. 1 shows a front view of the device carrier according to the invention from the street,

Figure 2 is a side view of the equipment carrier transverse to the direction of the road, and

FIG. 3 shows a top view of the equipment carrier,

Figure 4 shows a detail of the preferred embodiment of the equipment carrier of FIGS. 1 to 3 with additional mounting flanges.

Figure 1 shows an embodiment of a device carrier 10, comprising two vertical supports 12 between which a horizontal support bridge 14 is held. Each vertical support 12 stands on concrete foundations 16, on the upper side of which anchors 18 are provided for vertical support struts 20. In the present case, two vertical support struts 20 are arranged one behind the other in the depth of the image (FIG. 1), both of which are fastened on the same foundation 16. The foundation 16 has a portion 22 extending deeply into the floor and a portion 26 extending upward from the floor which, as can be seen better in FIG. 3, has the shape of a boat or an oval or ellipsoid. The vertical support struts 20 comprise a lower part 28, which is fastened to the anchors 18 of the foundations 16 and ends in a horizontal mounting flange 30 on its upper side. Above the mounting flange 30, the upper part 32 of the vertical support struts 20 extends to the upper end of the vertical support. The horizontal support bridge 14 is fastened to the upper part 32 of the vertical support struts 20 in a manner specified in more detail later. The horizontal girder bridge consists of two upper horizontal support struts 34, 36 and two lower 38, 40, the upper support struts 34, 36 lying one behind the other in the plane of the drawing in the same way as the lower support struts 38, 40. The upper and lower support struts 34, 38, 36, 40 are each connected to one another by technical-type diagonal struts 42 and possibly cross struts 43. The four horizontal support struts of the support bridge form a rectangle in cross section (FIG. 2) and the area between the lower horizontal support struts 38, 40 is preferably equipped with a walkable floor, so that the horizontal support bridge is used by maintenance personnel for the maintenance of devices 44, 46 can be. For this purpose, safety railings 48 are also provided on the horizontal girder bridge 14. From the horizontal girder bridge 14 there is thus direct access to the devices 44 which are held on the girder bridge itself, as well as to the bones 46 which are held on a vertical girder 12 on the median strip of the motorway. Since this carrier 12 is not accessible without interruption or disruption to traffic, these devices 46 can be moved into the maintenance position shown by reference numeral 46a via a slide guide 50, so that these devices 46 can be serviced without having to climb down on the carrier 12 , This is particularly important if the carrier - as in the exemplary embodiment - is arranged on a narrow median strip of a motorway.

The equipment rack 10 is designed for spanning at least two-lane roads, but especially for highways with six and mine lanes. The present illustration shows the overvoltage of a highway with three lanes 52 and one standing lane 54. The foundations 16 of the equipment carrier 10 are secured to the roadway side by guardrails 56, also to the oncoming lane 58. It goes without saying that there is one on the left vertical carrier 12 can extend the additional horizontal support bridge spanning the opposite lane 58, which is identical to the illustrated support bridge 14.

In order to increase maintenance reliability, a vertical ladder with a safety cage 60 is attached to the vertical support 12 in the side area of the freeway, so that maintenance personnel can safely climb into the accessible area of the horizontal support bridge between the horizontal support struts. The correct distance between the horizontal girder bridge 14 and the carriageways 52 is preferably approximately 5 m and the vertical distance between the upper and lower horizontal support struts 38 and 40, 34 and 36 is preferably 1.80 m to 2.50 m. FIG. 2 shows the side view of the equipment carrier 10 from FIG. 1. This view very nicely shows the diagonal struts 42 which run between the front and rear vertical support struts 20 and which considerably improve the rigidity of the overall construction. The elongated design of the foundation part 26 extending from the floor, which is designed in the manner of an oval or boat and has a high degree of collision safety, is further illustrated. The anchors 18 are fastened in the concrete foundation part 26 in a kind of internal reinforcement in the form of anchor baskets 62.

The rectangular space, which is formed by the four horizontal support struts 34 36 38 40, can be seen very clearly. This space represents the secured walk-in space for the maintenance of the devices, a walk-in floor being let in between the lower horizontal support struts 38, 40, so that the devices 44, 46 are easy to maintain. The construction is extremely rigid and torsionally rigid and can withstand high wind pressures. This is particularly important in the case of devices 44, 46 which comprise scanners, the functionality of which depends on exact positioning.

FIG. 3 shows the overall arrangement in supervision, here the oval shape of the foundation parts 26 of the foundations 16 protruding from the ground is well expressed.

FIG. 4 shows the connection of the horizontal support bridge 14 to the vertical support 12 in more detail.

The vertical support strut 20 of the vertical support 12 consists of the lower part 28, the upper side of which extends up to the horizontal mounting flange 30. This is where the upper part 32 of the vertical support strut 20 begins. From this upper part 32 two fastening flanges 64 branch off at a distance of approximately 1.8 to 2.5 m, to which connecting pieces 66 are flanged, which have a flange part 68 at one end for connection to the mounting flange 64 of the upper parts 32 of the horizontal support struts. From this flange part 68, a cylindrical tube 70 extends to a tab 72, which is shown in the figure at the bottom right in two views rotated by 90 degrees. This tab 72 is connected along a vertically extending mounting surface 74 to a complementary tab 76 at the ends of the horizontal support struts 34 36 38 40. With the adapter pieces 60, the horizontal girder bridge can be corrected to any length dimensions as well as inclinations. Preferably, the horizontal girder bridge 14 is composed of a basic module of a certain length z. B. 12 or 24 m and additional modules with a length of eg 1.20 m, which are simply flanged to the ends of the horizontal support struts. In this way, any distances can be covered in a linear pattern of 1, 20. In order to also be able to cover the values in between, the adapter pieces 66 are of different lengths, e.g. B. 4S and 24 cm can be used to cover all intermediate lengths. In this way, the fineness of the resolution of the length grid can be increased to 24 cm. In addition, the different lengths of adapter pieces 66 can be used to allow a certain inclination of the horizontal support bridge 14 during assembly, for. B. in cases where the highway itself is designed slightly inclined outwards, which is particularly advantageous for water drainage. Different lengths of adapter pieces are used here to compensate for the inclination. The tabs 72, 76 can compensate for a slight tilting through vertical elongated holes in the associated screw fastenings 78.

In addition to or instead of the diagonal struts, cross struts 43 can of course also be provided to increase the rigidity and / or for safety reasons for the accessible area.

Furthermore, in contrast to the exemplary embodiment shown, the horizontal support bridge 14 can contain all components up to the horizontal mounting flanges 30, i.e. be integrated with the upper part 32 of the vertical support struts 20.

For assembly on site, the horizontal support bridge with the adapter pieces 66 and the upper parts 32 of the vertical support struts are preferably preassembled, so that only the four assembly flanges 30, preferably self-centering via domes etc., need to be connected at the construction site. In order to keep the overall construction tension-free, after connecting the upper 32 to the lower parts 28 of the vertical support struts 20 on the mounting flanges 30, the connections on the brackets 72, 76 can be loosened again briefly, in particular to enable an inclination adjustment.
