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.
Description
- 1. Field of the Invention
- The invention relates to a bridge module for a suspension bridge installation, comprising an elongated floor and two upright side sections, which are connected to the lengthwise edges of the floor.
- 2. Prior Art
- Such a bridge module is generally known. The known bridge module is composed of separate sections, such as girders, floor, side sections and rests, which can be disconnected from each other. In constructing the known bridge module all these sections must be connected together, a process that needs time.
- An objective of the invention is to provide a bridge module of the type described in the preamble which can be set up more quickly. For this purpose, the bridge module according to the invention is characterised in that the side sections are hinged to the floor. In the bridge module according to the invention, the side sections can be folded against the floor, so that the bridge module can be easily transported and occupies little space when folded up. In order to make the bridge module according to the invention ready for use, only the side sections have to be folded up, so that hardly any time is needed.
- An embodiment of the bridge module according to the invention is 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.
- A further embodiment of the bridge module according to the invention is characterised in that the hinges preferably comprise two extrusion pieces that can be pushed into each other, and which can be turned at least 90 degrees with respect to each.
- Preferably each side section is made from one extrusion piece with cut-out openings, which extrusion piece is one of the extrusion pieces of one of the hinges.
- The floor also preferably comprises two girders with a plastic plate between them, which girders are each formed from one extrusion piece and one of the extrusion pieces is one of the hinges.
- A still further embodiment of the bridge module according to the invention is 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.
- The invention also relates to a suspension bridge installation comprising a bridge module according to the invention. Concerning the suspension bridge installation, the invention is characterised in that the suspension bridge installation also comprises a work cage, which can be connected to an end of the bridge module or can be 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 is provided on the other sides with connecting devices for connection to a bridge module and for the connection of an end rest to the work cage. Preferably the suspension bridge installation has at least two work cages, between which there are one or more bridge modules. The suspension bridge installation can be suspended on a tackling device with these work cages. The sides of the work cage to which no bridge module is connected can be closed off with an end rest.
- Note that this work cage can also be used with bridge modules other than the one according to the invention, and that this work cage can therefore also be protected independently of the design of the bridge module.
- Another embodiment of the suspension bridge installation according to the invention is characterised in that the suspension bridge installation also comprises 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 or a side of the bridge module.
- Note here as well that this tackling unit can also be used with bridge modules other than the one according to the invention, and that this tackling unit can therefore also be protected independently of the design of the bridge module.
- The tackling unit here forms a composite whole of tackling mechanism and connecting devices so that the tackling mechanism can be easily connected to the bridge module. Providing the tackling unit with wheels allows it to be used as a trolley, which can be easily moved.
- The connecting devices comprise preferably bottom and top connecting elements, and two prongs that extend at right angles to the box and are connected to the bottom connecting elements.
- Still another embodiment of the suspension bridge installation according to the invention is characterised in that the suspension bridge installation also comprises 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. The cage frame protects the tackling unit from damage if it inadvertently falls.
- Also note here that this tackling unit can also be used with bridge modules other than the one according to the invention, and that this tackling unit can therefore also be protected independently of the design of the bridge module.
- This tackling unit also here forms a composite whole of tackling mechanism and connecting devices so that the tackling mechanism can be easily connected to the bridge module. Also providing this tackling unit with wheels allows it to be used as a trolley, which can be easily moved.
- An embodiment of the suspension bridge installations according to the invention as described above is characterised in that the suspension bridge installation also comprises at least one connecting module, which can connect the bridge module to a further bridge module or a work cage 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.
- A further embodiment of the suspension bridge installation according to the invention is characterised in that each leg comprises two sections that are hinged together, and 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. This means separate pins are not needed to lock the sections together.
