over the H\u00fcnnesbach on the road &#8220;Gr\u00fcner Weg&#8221; was built in 1967 as a passage building in the form of a brick vault.\u00a0During the last building inspection, serious damage was found and the building was classified with a limited stability.\u00a0In order to reduce the load on the building, the use for road traffic has been blocked.\u00a0However, the building is currently still open for pedestrians and cyclists to use.<br \/><br \/>In order to restore the accessibility of the &#8220;Gr\u00fcner Weg&#8221; road, the existing building is demolished and a replacement building erected.\u00a0The planned replacement building is to be erected at the same location as the existing building.\u00a0The replacement building will be constructed as a bridge structure in timber-concrete composite and spans the H\u00fcnnesbach with a length of 10.20 meters and a width of 4.50 meters.\u00a0Due to the now larger span, the flood cross section of the H\u00fcnnesbach is now considered sufficiently.\u00a0The bridge is designed according to DIN EN 1991-2 load model 1 for heavy load traffic.<br \/><br \/>With the timber-concrete composite construction, the properties of the individual materials are used efficiently, the concrete slab predominantly absorbs pressure and the wooden beams predominantly tensile stresses.\u00a0The bridge is planned as a two-tier girder and executed in a simple and functional way.\u00a0Due to the concrete superstructure, all detail training according to ZTV-ING and RiZ-Ing (BASt) can be fulfilled.\u00a0The balustrade are planned with a handrail made of acetylated glued laminated timber, which differs from the type Gel 4 directional railing, indicating to the user on the bridge the special structure of the bridge.<\/p>\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t<div class=\"elementor-element elementor-element-d5562e1 e-con-full ci-right e-flex e-con e-child\" data-id=\"d5562e1\"
