Abstract

The joint gap spanning system for bridges and similar structures has components (3), displaceable across the gap between two bridge components (1) and a control device with a guide rod, maintaining constant intervals between the components. The components are connected in each case by a gude rod (20) which can swing in the vertical plane. On each guide-rod one end is mounted in a fixed hinge joint, and the other in a hinge joint which is vertically displaceable against spring action. The ends of paired guide rods may be mounted in a common hinge joint on a displaceable component, which may be vertically movable and spring-loaded.

Description

"Joint bridging construction for

Bridges or similar structures "The invention relates to a joint bridging construction for bridges or similar structures with at least a component that can be moved between two stationary components in the direction of the joint and a handlebar, the distances between the individual components of the same size holding control device.

There are already various control devices for joint bridging structures named of this type; from DT-PS i 271 742 is a cover device for a Expansion joint in bridges or the like with one always held in the middle of the latter Joint cover plate known, which is supported on opposing surfaces of the joint edges and ir.i cross-section is roof-shaped and with its longitudinal edges in accordingly outwardly inclined, to the top and Underside of the joint cover plate parallel slots engages at the joint edges, being below the apex the joint cover plate vertical pins are arranged, each of which is axially displaceable i the bearing of an isosceles lever engage, the ends of which on the two Edge beams are guided in the longitudinal direction of the joint. In this known joint cover plate The handlebar used is one-piece and thus leads from one. stationary component for other stationary components; this control device can be any different Do not adjust the set tongues of the joint edge supports.

From the German patent specification 1 162 8a3 is one of several Handlebars existing joint covering device with a cover plate known in the each individual link in the longitudinal center of its approximately in the longitudinal direction in the 'u, e running middle part on the underside of the cover plate and over two shorter ones Swivel arms on the joint side walls or the undersides of the edge can be swiveled connected. In this joint covering device, too, is in turn the Central component to be held connected to a continuous handlebar; not to mention of the fact that in this, as also be the above-mentioned joint covering device, only a single displaceable component - namely the cover plate - can be provided can, this control device can accommodate different settlements of the joint edge supports not follow DT-PS 2 103 415 is a covering device for Dennungsfugen of the type mentioned in the introduction is known in which, on the one hand, a watertight seal is provided and the other hand using several shifters Components can be used: this Abaeckvorrichtung is for uniform Alignment of the movable components a so-called "Nuremberg scissors provided, which is not only complex in its construction, but also a lot of material and space claimed; sheared off daven cause the numerous provided Joints may make rattling noises and must be removed or installed at a later date only possible with great difficulty.

The invention is based on the object of a control device for to create a joint bridging structure of the type mentioned in the opening paragraph, which is not only extremely simple in its construction, but also relatively few parts and space leaned.

The object is achieved in that, according to the invention, each component with an adjacent component by a pivotable in the vertical plane Link is connected and that one end of the respective link in a stationary Joint and the other end of the same in a vertically displaceable against spring action Joint are mounted.

According to a preferred embodiment of the invention, the ends are of two links in a common joint of a displaceable component stored; the common joint can be displaceable in the vertical; the common Joint can spring-loaded, preferably compression spring-loaded. As in most cases the maximum spring force should be available when the joint is fully open and also the use of tension springs is not always desirable Embodiment decisive advantages in practice.

A further development of the invention consists in that the joint consists of a toggle rod, which is connected to a piston or the like or is stored in / on this, which is provided in a below the component Housing is vertically displaceable. In this Case is preferred a compression spring used.

Two pairs of handlebars can each have a spring action vertically displaceable joint rod @@ displaceable component be connected.

The control device designed in this way forms a constructive one in itself Unit and can be used at least twice, often in a joint bridging construction however, several times are provided.

If the joint bridging construction has at least two movable Components are provided, can according to a further embodiment of the invention the links, each articulated to a displaceable component, alternating in or / regular Repeatedly fixed and displaceable at intervals. The one just mentioned structural unit of a control device is thus displaceable in the case of several Components provided successively offset from one another.

Appropriately, the links are each vertically displaceable provided end with a longitudinal slot. This measure makes it possible e.g.

an inevitably half-open joint on one side completely with the corresponding To open the tool in order to carry out any measures or to replace the sealing body, for example to undertake. Such a measure has so far been discussed in the case of control devices standing kind had not been known.

It is particularly useful to use the two ends that are supported together of a pair of handlebars to be provided with longitudinal slots.

As already mentioned above, compression springs have been used particularly proven for the purpose in question; therefore it is possible that the Suspension of a control device (i.e. a structural unit) from a consists of single compression spring; the compression spring can in turn be made up of several compressible Cushions made of cellular polyurethane, possibly in a square Steel housing are stored.

The drawing shows exemplary embodiments of the subject matter of the invention shown. They show: Fig.l) a cross section through a joint bridging structure with the joint fully open, Fig. 2) a section along line 2 - 2 in Fig. 1 FIg-.3> a section along line 3 - 3 in Fig. 1, Fig. 4) a plan view a modified embodiment with two movable components under partial Omission of the superstructure and FIG. 5) a section along line 5 - 5 in FIG. 4.

Between two stationary components 1 designed as edge supports and 2, for example made of metal, is a slidable component designed as a lamella 3 arranged.

The upper edge 4 of all components is flush with the upper edge of the road, e.g. a road bridge.

In the embodiment shown are the displaceable components Each provided with recesses 5 to accommodate sealing bodies that are watertight Ensure completion of the substructure of the joint bridging construction.

However, the invention is also applicable to other joint bridging constructions, e.g. those with joint cover plates can be used.

The edge beams 1 and 2 are each with a 2W? Joint open box 6 and 7 connected in the road substructure.

The boxes are, as described below, in the respective Joint edges of the structure anchored.

Boxes 6 and 7 contain two tabs 9 or two in pairs. 10 attached, these tabs are each provided with holes 11 and 12 respectively. A round steel bolt 13 resp. 14 inserted through.

The round steel bolts 13 and 14 are each stored between the. to wash the lever 20 or 21. These levers or

Handlebars are in a vertical plane running across the joint runs, pivoted.

Below the displaceable component 3 is a square steel housing 22 attached, which is open at the bottom.

The steel housing 22 points to the two extending in the longitudinal direction of the joint Pages 23, 24 vertical longitudinal slots 25.

In the steel housing 22 there is a sliding piston made, for example, of plastic 30 mounted vertically displaceable. A toggle rod 31 is through the sliding piston passed through, the connection between the sliding piston and the two levers 20.21 manufactures. In each of the levers 20, 21 longitudinal slots 32 and 33 are provided, whose function is explained in more detail below. The link rod 31 is as Screw bolts which is secured with a locking nut 36, for example. Between respective @uttern of the screw bolt and the links 20 are plastic washers 34, 35 provided, which serve not only as washers, but also for a Noiseless swiveling of the handlebars 2O, 21 should provide.

between the sliding piston 30 and he upper wall 7 and the steel housing 22 a compression spring 38 is provided; this compression spring exists in the case of the one shown Embodiment consisting of four composite cellular polyurethane cushions 39.

The position of the handlebars shown at the maximum opening of the joint according to Fig. 1 and Fig. 3 also shows the maximum compression of the Compression spring @@; when closing the joint, the handlebars 20 and 21 pivot with their lower ends towards the edge of the joint, so that the compression spring 38 relax can. By resting on the toggle rod 31 it is ensured that the displaceable Component 3 has a central position at each distance between the stationary components 1 and 2 occupies.

In addition, the compression spring 38 can of course at least be slightly pretensioned.

With the joint open and thus the compression spring compressed to the maximum 38 it is possible to move the central or displaceable component 3 from its central position, e.g. by pressing to move sideways. This shift is made possible by that the toggle rod while maintaining its vertical position within the longitudinal slots in the links 20 and 21 shifts.

As the horizontal component of the contact surface for the articulated rod in the longitudinal slots is sufficient to keep the spring compressed to the maximum the postponement From middle component 3 possible, so that any sealing body clamped in the recesses 5 can be exchanged @@ earth; even it is possible after any removal of the sealing body - provided it is of course A watertight joint bridging construction is concerned - wringings, repairs or to replace parts of the joint bridging structure in the substructure.

The self-contained control device called the constructive unit with two pairs of links and a link rod is multiple, but at least twice, provided in a joint.

The control device referred to as the structural unit it, however can also be used without further ado; where it is provided as a slidable component is.

In Fig. 4 and 5 is an embodiment with two displaceable Components 40, 41 shown between two stationary components 42, 43.

While the articulation of the handlebars 44 in the open box 45 on the in the same way as in the embodiment described above the links 47 connected to these links via the link rod 46 on the substructure of the displaceable neighboring component 41 articulated by, in turn, in pairs arranged tabs 48,49.

As can be seen from FIG. 5, these ashes are located directly on the underside the sliding. Component 41 attached.

The links 50 are articulated in the box 51 in a corresponding mirror image and connected to the links 53 via the toggle rod 52 in a positively movable manner. These handlebars @ 3 are in turn via tabs 54, 55 on the underside of the sliding Component 40 articulated.
