    | The current invention relates to a pedestrian bridge for bridging building puddles and the like such as canals or trenches. More specifically, the invention is intended to bridge construction routes that are temporarily created in the public highway by carrying out works on utility services located underground, such as zivol pipes, water and gas pipes, power lines and data communication cables.
    During the execution of the works, pedestrians who move along the footpath on the ground floor must be temporarily provided with an emergency bridge for the construction pits.
    In practice, for emergency bridging, a few barriers are often used, over which the pedestrians have to move. that prevent pedestrians from ending up in the construction pit to be crossed.
    | To overcome this drawback, 9 sensible bridges have been developed, provided with openings, into which handrails are placed on both sides of the | pedestrian bridge, Lemmingen To which the crossing 9 2 pedestrian can hold on and which prevent the 9 pedestrian from losing balance and falling off the pedestrian bridge, 9 in practice the pedestrian bridge will be composed 9 10 of a bridge deck consisting of two sloping treads connected by a horizontal surface and consisting of two railings, one on each long side of the horizontal surface of the bridge deck, The two railings are fitted through each railing with each of its two ends sliding into openings in the bridge deck provided for this purpose. arises when the openings into which the handrails are inserted to secure them Le are subject to thermal expansion or contraction.
    This leads to the openings expanding in hot weather and the handrails no longer providing sufficient support because they have become too large, and the openings to shrink in cold weather and become too small to still receive the handrail.
    Another problem arises when the openings are too close to the boundary line of the horizontal wage plane with a short running plane, whereby the openings are subject to tearing, for instance as a result of the repeated bending of the bridge deck under a heavy load.
    | ; BE2019 / 5437 The present invention has for its object to offer a solution to the aforementioned and other drawbacks, by providing a pedestrian bridge for bridging | construction pits, where the pedestrian bridge comprises at least gen: 3 bridge deck, provided with a horizontal walking surface between two sloping walkways and with at least two railings, | one on each longitudinal side of the horizontal tread of the bridge deck, the horizontal tread being provided with # rectangular openings for catching the ends of the handrails LE, and two rectangular openings being provided for each handrail, these openings always being be positioned at a distance of at least 8 cm from the boundary line between the horizontal surface and an inclined walking surface,
    An advantage of such a pedestrian bridge is that the railings can always be attached to the bridge deck by placing the railings with their ends in the rectangular openings Le places provided thereon, which allow some play so that the railing always fits, regardless of the prevailing atmospheric temperature. the bridge deck is made of plastic by means of injection molding in a mold, whereby the bridge deck is reinforced at the bottom by a honeycomb structure with the aim of limiting the bending of the bridge deck under heavy loads and thereby reducing the risk of tearing of the openings in which the Handrails are fitted to limit or prevent Le, aided by the distance of at least 8 mm from the openings to the boundary line between the horizontal tread and an inclined icopviax. | Preferably, the top of all locomotive surfaces is provided # 5 with a raised pattern in plastic, with the aim of protecting the user against sliding when crossing the bridge deck by offering more grip to the | footwear of the pedestrians.
    This raised pattern in 9 synthetic fabric can be a honeycomb pattern,
    When pouring in a mold, the eyelets are surrounded by plastic walls before the railings fall over their entire depth in order to properly support the railings, whether or not closed by a plastic bottom connecting the four walls.
    Preferably, the handrails are made of galvanized steel and each handrail is provided with two ends that fit into the openings provided for this purpose along each side of the bridge deck. An advantage of such handrails made of galvanized steel is that they are resistant to corrosion and are sufficiently strong. to support the feelers and prevent a fall into the construction pit.
    Preferably, each handrail is made of a galvanized steel pipe or profile, which is folded equidistantly from each end at an angle of 90 ° to form two supporting legs under a middle straight piece that serves as a handrail.
    ; BE2019 / 5437 2 of the two supporting legs are provided with 9 ends that fit into the openings provided in | the bridge deck, [3 Each picoid railing can be provided with a 9 protective plate made of metal, which connects the two supporting legs to each other and gives the railing more rigidity: Preferably the bridge deck is provided on one longitudinal side with a groove 9 Le and on the opposite longitudinal side of 9 a Land, whose only intended functionality is to be able to connect abutting bridge decks with each other by a simple tongue and groove connection.
    With the insight to better demonstrate the features of the invention, a preferred embodiment of a Voelbridge according to the invention is described below, by way of example without any limitation, with reference to the accompanying drawings, in which: figure 1 shows a top view of the bridge deck of a pedestrian bridge according to the invention: figure 2 shows a side view of figure 1; figure 3 represents a bottom view of fiquur 1; figure 4 shows a perspective view of a pedestrian bridge with handrails according to the invention. Figure 1 schematically shows a top view 1 of a bridge deck 2 for a pedestrian bridge according to the invention, with at the top two pairs of openings 7, 7 "for a bridge railing, one on each longitudinal side of the tread 3,
    Each pair consisting of two rectangular openings; 75, 7'b and Yes, Yes, The openings are located at a distance of at least B around the boundary lines between the horizontal tread 3 and the sloping lye surfaces Za and 3b, which treads are provided on the top with a honeycomb structure 4, 9 As Dok can see from the side view in figure 2, the bridge deck Z consists of three parts: a horizontal rectangular tread 3 which is provided on both short sides with a sloping surface ja and 3 ». In figure 3 a bottom view is shown of the bridge deck forming one horizontal plane 5 of three parts, namely a middle part 6 supporting the horizontal rectangular lye plane 3 and having a constant thickness and the parts 6a and 6b extending under the sloping treads 3a and 36 are located with decreasing thickness towards their end. Dock this lower horizontal plane 5 is provided with a honeycomb structure 4 and the edge d 'is visible which can fit in a groove of an adjacent bridge deck 2. In figure 4 a pedestrian bridge 8 is shown. according to the invention, consisting of a bridge deck 2 on which two handrails 9, 9 ° are arranged, one on each longitudinal side of the tread 3 of the bridge deck 2, in which on each long side L two openings 7a, 76 and 7a, 7'b are provided to respectively slide in the handrails 9, 9 ° with their ends 11, which handrails are provided with a protective plate 12, horizontal tread 3 and inclined sloping treads 3a and 3b z ijn to the
    - BE2019 / 5437 top provided with a serrated raised pattern 10 | in plastic, in this case a honeycomb cartridge, to | To prevent the pedestrians from sliding out, 9 The operation of the pedestrian bridge 8 according to the invention 9 is very simple and as follows.
    In order to provide a construction pit with a pedestrian bridge 8, a bridge deck 2 of plastic is laid over the construction pit with the raised honeycomb pattern 4 facing upwards, the two sloping running surfaces 3a and 3b being supported by the edges of the construction pit.
    Then the two railings 9, 9 'are fitted on the bridge deck 2 by inserting each railing with their ends 11 into the rectangular openings 78, 7 ° a and 70, 7'b, so that the two railings 9, 9 always fit and firmly. are contained in the bridge deck 2 made of plastic, The pedestrian bridge 8 is now ready for use and is able to limit the bending of the bridge deck due to heavy loads by means of the reinforcing honeycomb pattern 4, 10 on the bottom and on the top of the bridge deck 2, thus preventing or limiting the tearing or loosening of the railings 9, 9 °, The raised honeycomb pattern 10 on the top of the bridge deck 2 helps the feeder to maintain a firm grip on the bridge deck 2 and to extend it appearance.
