Bridge module

Abstract

A bridge module has a floor and two upright side sections, which are hinged to lengthwise edges of the floor. Each hinge is formed by two extrusion pieces that can be pushed into each other, and is made so that the side sections can only be folded towards the floor in a direction towards each other. Each side section is made of one extrusion piece, in which a section of the extrusion piece forms a section of the hinges. The edges of the floor are formed by girders, between which there is a plastic plate. The girders are each formed of one extrusion piece, which forms the other section of the hinges.

1 . A bridge module for a suspension bridge installation, the bridge module comprising:
 an elongated floor having lengthwise edges;   two upright side sections; and   hinges for connecting each of the upright side sections to one of the lengthwise edges of the floor.   
   
   
       2 . The bridge module according to  claim 1 , characterised in that the hinges are made so that the side sections can only be folded towards the floor in a direction towards each other. 
   
   
       3 . The bridge module according to  claim 1 , characterised in that the hinges each comprise two extrusion pieces that can be pushed into each other, and which can be turned at least 90 degrees with respect to each other. 
   
   
       4 . The bridge module according to  claim 3 , characterised in that each side section is made of one extrusion piece with cut-out openings, which extrusion piece is one of the extrusion pieces of one of the hinges. 
   
   
       5 . The bridge module according to  claim 4 , characterised in that the floor comprises two girders with a plastic plate between them, which girders are each formed of one extrusion piece and one of the extrusion pieces is one of the hinges. 
   
   
       6 . The bridge module according to  claim 1 , characterised in that the bridge module also comprises rests, which are present at a distance above the side sections and are connected to the side sections by elastic bands. 
   
   
       7 . A suspension bridge comprising:
 a bridge module comprising an elongated floor and two upright side sections, which are connected to lengthwise edges of the floor, characterised in that the side sections are hinged to the floor; and   a work cage that can be connected to an end of the bridge module or installed between two bridge modules, which work cage comprises a floor, which when connected to the bridge module is connected to the floor of the bridge module, and which work cage comprises a box on one side and on the other sides is provided with connecting devices for connection to a bridge module and for the connection of an end rest to the work cage.   
   
   
       8 . The suspension bridge of  claim 7 , further comprising a tackling unit, which is provided with a box with a tackling mechanism therein, which tackling unit is also provided with connecting devices for connecting the tackling unit to an end of a side of the bridge module. 
   
   
       9 . The suspension bridge according to  claim 8 , wherein the connecting devices comprise bottom and top connecting elements, and two prongs that protrude at right angles to the box and are connected to the bottom connecting elements. 
   
   
       10 . The suspension bridge according to  claim 7 , further comprising a tackling unit, which is provided with a cage frame with a tackling mechanism therein, which is fastened to the cage frame, which cage frame is provided with connecting devices for connection to the bridge module. 
   
   
       11 . The suspension bridge according to  claim 8 , further comprising at least one connecting module, which can connect the bridge module to a further bridge module or a work cage also belonging to the suspension bridge installation, which connecting module comprises a bottom section with four upright connecting pins, for engaging holes in the floor of the bridge module and the further bridge module and/or work cage, and two legs, to which the side sections and the rests can be connected. 
   
   
       12 . The suspension bridge according to  claim 11 , wherein each leg comprises two sections hinged together, which can be locked together with a locking pin, which locking pin can be moved to clamp in a hole in one of the sections. 
   
   
       13 . A suspension bridge comprising:
 a bridge module for a suspension bridge installation, the bridge module comprising an elongated floor having lengthwise edges; two upright side sections; and hinges for connecting each of the upright side sections to one of the lengthwise edges of the floor;   a work cage adapted to be connected to an end of the bridge module, or installed between two bridge modules, the work cage having a floor that is adapted to be connected to the floor of the bridge module when the work cage is connected to the bridge module, and which work cage further comprises a box on one side and on the other sides is provided with connecting devices for connection to a bridge module and for the connection of an end rest to the work cage; and   a tackling unit, which is provided with a box with a tackling mechanism therein, which tackling unit is also provided with connecting devices for connecting the tackling unit to an end of a side of the bridge module.   
   
   
       14 . The suspension bridge according to  claim 13 , wherein the connecting devices comprise bottom and top connecting elements, and two prongs that protrude at right angles to the box and are connected to the bottom connecting elements.
