Anti-falling cover net for left and right amplitude middle gaps of overpass railroad bridge and mounting method thereof

Abstract

The invention discloses an anti-falling cover net for left and right amplitude middle gaps of an overpass railroad bridge and a mounting method thereof, and belongs to the field of railway bridges. The anti-falling cover net comprises a bracket and a mesh; the bracket comprises supporting parts and lap joint parts; the supporting parts comprise supporting beams and connecting beams; the supportingbeams are transversely arranged, the connecting beams are arranged at the left ends and the right ends of the supporting beams and obliquely extend upwards to be symmetrically arranged; the multiplesupporting parts are arranged in parallel; the lap joint parts are horizontally arranged and connected with the upper ends of the connecting beams; the lap joint parts are connected with multiple connecting beams; the axis of the lap joint part is perpendicular to the axis of the supporting beam; the bracket is installed between the left anti-collision wall and the right anti-collision wall through the lap joint parts; and the bracket is in a big-end-up groove shape. The shape of the mesh is the same as that of the bracket, and the mesh is arranged on the bracket. The bracket is made of galvanized steel and is lighter; the performance of the steel is utilized, so that the bracket can better adapt to up-down vibration and horizontal micro-displacement of left and right bridges; the anti-falling cover net is installed on the top of the anti-collision wall, and construction is safer and more convenient; and the mesh not only plays a role in preventing falling, but also prevents water fromaccumulating in the groove.

Description

technical field [0001] The invention relates, in particular, to an anti-drop cover net used in the left and right middle gaps of overspan railway bridges and an installation method thereof. Background technique [0002] Such as figure 1 As shown, in the prior art, a concrete cover plate 4 is generally provided at the bottom corner between the left and right anti-collision walls 3 to form a groove, and water leakage treatment is required. It is mainly to prevent the rainwater in the middle of the left and right panels from flowing down to the railway catenary in a line. In addition, it can prevent the communication pipe box and support from falling. The width of the step reserved for installing the cover plate in the middle of the left and right sides of the bridge is relatively narrow, because the bridge will have a certain vibration amplitude during the passage, so the concrete cover plate 4 will be squeezed and broken or there is a risk of falling. Concrete cover plate 4...
