Semi-permanent protection device for bridge floor of cable bridge

Abstract

The invention discloses a semi-permanent cable bridge deck protection device which comprises cable bridge decks, rubber layers, fixing angle steel and supporting steel plates, the cable bridge decks are installed on steel cables after being mutually spliced, the supporting steel plates are installed on the upper end faces of the cable bridge decks, and the rubber layers are laid on the upper end faces of the supporting steel plates. The two sides of the rubber layer are bent and then installed on the bridge deck of the cable bridge through fixing angle steel, the fixing angle steel is connected with the bridge deck of the cable bridge through locking bolts A, and the rubber layer is clamped between the fixing angle steel and the bridge deck of the cable bridge. The rubber layer has toughness and skid resistance, plays a role in protecting the bridge floor and also has certain skid resistance, when the fixing angle steel is installed, the fixing angle steel is installed on the two sides of the bridge floor, the fixing angle steel and bolts are prevented from being damaged by equipment, the skid resistance is improved while the bridge floor is protected, and the service life of the bridge floor is prolonged. The maintenance cost of the cable bridge is greatly reduced, meanwhile, the rubber layer is also easy to replace, and the maintenance difficulty is reduced.

Description

technical field [0001] The invention belongs to the field of infrastructure engineering construction, in particular to a semi-permanent cable bridge deck protection device. Background technique [0002] The cable bridge, also known as the suspension bridge, mainly bears the weight of the bridge road surface through the steel cables suspended on the cable towers. In the construction process of some dams and other projects, cable bridges will be used to lay roads such as crossing rivers. The bridge deck of traditional cable bridges does not have any protective devices. Some large equipment passing through the cable bridge will have a strong impact on the bridge deck parts. Destructive, such as nuts, will reduce the life of the cable bridge deck; at the same time, in order to ensure the robustness of the cable bridge, the bridge deck is mostly made of metal materials, and the load-bearing equipment is prone to slipping through the bridge deck, which affects the transportation e...
