PEDESTRIAN BRIDGE Russian patent published in 2018 - IPC E01D15/20 

FIELD: construction.

SUBSTANCE: invention relates to the field of bridge construction. Pedestrian bridge of the hinged type contains two supports with staircases fixed at the installation site, several identical bridge sections connected to each other and to supports. Each section of the bridge contains a barostatic panel made of a light and durable material with longitudinal hollow cavities, inside of each of which identical barostatic elements are arranged in two rows in the longitudinal direction, and in the transverse direction the number of them is not limited and depends on the width of the panel. Each barostatic element contains two longitudinal rectangular E-shaped vertical cavities that are not pneumatically connected to each other and are turned towards each other by their three lateral channels, closed on both end faces. Lowest channels of both E-shaped cavities are deaf, and each of the upper channels is pneumatically connected to a corresponding vertical longitudinal channel opening onto the upper surface of the barostatic panel, but by means of an inclined longitudinal channel with an internal cavity of a corresponding longitudinal pipe, closed from both end faces. Middle longitudinal channels of both E-shaped cavities are connected to the inner cavities of the other two longitudinal pipes, closed on both end faces. All the opposite walls of E-shaped cavities are equal in area, symmetrical to each other, are opposite each other. Middle longitudinal channels and the inclined longitudinal channels of both E-shaped cavities are so connected to the longitudinal pipes that each segment of the arc of one tube is symmetrical and equal in area to the cross-lying segment of the arc of the other pipe. On the top surface of the barostatic panel are installed in the lid guides with the possibility of moving in the transverse direction. Barostatic panel is closed with a U-shaped protective casing installed on vertical racks made on barostatic panels with a gap on the top and sides to access the atmospheric air panels. U-shaped casing with one side has a flap for access to the barostatic cover. On the U-shaped casing, which is also the upper deck, the side fences are fixed, the place of the hinged connection of the barostatic panels is covered by a spherical peak, and at the junctions of the barriers between the barostatic panels, protective chains are installed.

EFFECT: invention makes it possible to improve the performance of a pedestrian bridge, does not require the installation of intermediate supports, simplifies the installation and disassembly of the bridge.
