Description

The invention relates to a collapsible bridge for civil and military purposes consisting of at least two uniform bridge sections, the are coupled together by connecting elements.

DE 41 26 250 A1 describes one of several Track carriers trained uniform Existing bridge sections known, where one or more bridge sections assembled to form a bridge. The ends of the Track carriers have fixed ramps that are comb-like are slipped. The track carrier can according to your Assembly in connection with the swung out Undervoltage that occurs when driving Take up compressive forces and bending moments.

After inserting two track carrier elements into one another the adjacent tines grip like projections of the ramp of a track carrier in the opposite tines of the other Track carrier. The track supports of the bridge sections are Can be connected to each other using telescopic cross tubes.

Such chamber-like projections in the driveway form a bridge system for certain vehicles with narrow tires and for pedestrians in the dark a danger spot. Another disadvantage is that a Bridge element is made up of several assemblies and a special device is needed to build a bridge with it to build up or to dismantle.

In DE-PS 19 27 273 connecting elements for Connecting two swiveling on floating bodies connected ramps with U-shaped brackets and Locking means described with which the two  superimposed ramps rigidly connected become. According to this document, each ramp instructs a U-shaped bracket on the underside for insertion the ramp tip of the respective lower ramp and at least one spaced from the U-shaped bracket arranged between this and the ramp tip of Plug-in locking device on top.

The invention has for its object to provide a collapsible bridge for civil and military purposes, which has the following features:

• - use of a one-piece basic element,
• - simple type of coupling of the basic elements,
• - unlimited use for everyone Vehicles and pedestrians.

The task is solved in the way it is in the characteristic features of the main claim is specified. Advantageous embodiments of the Invention are the subject of the dependent claims.

The dismountable bridge according to the invention stands out characterized in that for the quick assembly of a bridge consisting of at least two sections only uniform basic elements are used, the ent speaking of the installation situation either as End sections or used as inner sections become.

The dismountable bridge according to the invention must consist of a even number of basic elements assembled be, for example, two, four, six and more Basic elements.  

The basic element, which can be rotated by 180 °, consists of:

• - a rectangular cross-section,
• - a ramp end with vertical holes for Fasteners,
• - a drivable surface on the top and Bottom and
• - An inner dome side with at least two next to it each other, offset in height, arranged before jump with horizontal holes for connection elements.

One of the basic elements according to the invention Assembled bridge can also be in the form that the end sections Have basic elements, the ramp area upwards are directed.

Embodiments of the invention are as follows explained in more detail using schematic drawings.

Show it:

Fig. 1 is a side view of a bridge consisting of four basic elements,

Fig. 2 is a perspective view of a basic element with an overhead ramp and

Fig. 3 is a perspective view of a basic element with a ramp below.

Fig. 1 shows a bridge composed of four basic elements ( 1 ), which has two end elements ( 2 ) and two inner elements ( 3 ). The left inner element ( 3 ) is rotated by 180 ° in its longitudinal direction and lies with its ramp ( 9 ) on the ramp ( 9 ) of the right inner element ( 3 ). The end members (2) '(8 by means of connecting elements), which are inserted into the horizontal holes (8), connected at their projections (5, 5)' to the inner elements (3) detachably. The two ramps ( 9 ) of the inner elements ( 3 ) are connected to one another by connecting elements ( 10 ') which are passed through vertical bores ( 10 ).

The basic element ( 1 ) shown in perspective in FIG. 2 has protrusions ( 5 , 5 ') on the end faces ( 4 ) to be coupled, which are offset in height next to one another.

The interface ( 6 ) of the projection ( 5 ) is just like the road surface ( 7 ) and the interface ( 6 ') of the projection ( 5 ') is just like the road surface ( 7 ').

The base element ( 1 ), opposite to the end face ( 4 ), has a drive-on ramp ( 9 ) into which vertical bores ( 10 ) are made to accommodate connecting elements.

Fig. 3 shows a perspective view of the base element, which is drawn rotated by 180 ° compared to Fig. 2 and is used in this position, for example, as a left inner element ( 3 ) in the bridge of Fig. 1.

Claims (1)

Detachable bridge for civil and military use, consisting of at least two uniform bridge sections which are coupled together by connecting elements, characterized in that the bridge can be assembled from an even number of uniform basic elements ( 1 ) such that each basic element ( 1 ) has a ramp at one end ( 9 ) with at least one vertical bore ( 10 ) for receiving connecting elements ( 10 ') for connecting the ramps ( 9 ) of two basic elements ( 1 ) and each basic element ( 1 ) at the other end offset in height, arranged side by side projections ( 5 , 5 '), each projection ( 5 , 5 ') having at least one horizontal bore ( 8 ) for receiving connecting elements ( 8 ') for connecting the projections ( 5 , 5 ') of two basic elements ( 1 ) and that each basic element ( 1 ) has a plurality of passable surfaces ( 6 , 6 ', 7 , 7 ', 9 ).
