Steel mesh bridge

Abstract

The invention provides a steel mesh bridge consisting of a plurality of U-shaped cross beams and longitudinal ribs, wherein the connection points of the U-shaped cross beams and the longitudinal ribs are located on inner sides of the longitudinal ribs; at least one end of the steel mesh bridge is a head end provided with two U-shaped cross beams with a closer distance, a segment of the longitudinal rib connected with the two U-shaped cross beams on the head end is bent inward to form a groove, so that the two U-shaped cross beams on the head end are located in the groove of the longitudinal rib, the parts of two side edges and bottom margins of the two U-shaped cross beams on the head end of the steel mesh bridge located between two adjacent longitudinal ribs are provided with projections protruding to the outer sides, and the projections can limit the two side edges and bottom margins of the two U-shaped cross beams of the conventional steel mesh bridge so as to prevent drop-out; and no connection strap needs to be additionally arranged, thereby being convenient to install and connect, small in mass and volume, reliable to connect, convenient to install and transport, small in the number of parts and components, simple in production and manufacture processes, short in engineering construction time and high in economic benefit.

Description

technical field [0001] The invention relates to a steel net bridge, which is specifically applied to cable laying in power transmission and transformation equipment in the electric power industry. Background technique [0002] In the prior art, the connection parts of the mesh bridge generally use independent connecting pieces to fasten and connect with bolts, and the connection and fastening of bolts on the mesh bridge is relatively difficult; the independent connecting pieces need to be surface cleaned, and various processes such as adding an anti-corrosion layer The processing and process are complicated, and the number of parts is large, the production and manufacturing are cumbersome, the construction time is long, and the packaging, handling, installation and transportation are inconvenient. Contents of the invention [0003] The technical problem to be solved by the present invention is to provide a steel mesh bridge that can be quickly connected, easy to operate, a...
