Light low cost durable cable bridge

Abstract

The invention relates to a cable laying device, especially to a light low cost durable cable bridge. The light low cost durable cable bridge consists of a board card, bolts, a tinned iron sheet, waterproof paint, a bamboo plate, a constructional column and a transverse reinforcement. Wherein, the surface of the bamboo plate is coated with a layer of the waterproof paint. Two fixing parts horizontal slots are arranged oppositely. Two ends of the bamboo plate are inserted into the two horizontal slots of the fixing parts and are fixed through the bolts, a U-shaped framework is formed by the bamboo plate and the board card, and the surface of the U-shaped framework is covered with a layer of the tinned iron sheet. The utilized main materials of the light low cost durable cable bridge are board bodies overlaid by bamboo chips, compared to steel, aluminum alloy materials in the prior art, the manufacturing cost is lowered, the phenomenon of sinking is effectively avoided, and the durable life is longer.

Description

technical field [0001] The invention relates to a cable laying device, in particular to a light-weight, low-consumption and durable cable tray. Background technique [0002] The existing U-shaped cable trays are usually made of thicker steel in order to meet their load-bearing capacity. Therefore, the produced bridges are heavy in weight, high in transportation and production costs, and labor-intensive for workers during installation. It is also prone to subsidence phenomenon. In order to solve this problem, opening holes on the U-shaped frame to reduce the weight of the bridge frame, or setting metal reinforcement ribs to reduce the thickness of the bridge frame, but this solution is very important for reducing the amount of steel. There is no obvious help, and at the same time, the structure of the cable tray is complicated, and the cost of man-hours is increased, so the cost of the cable tray is not fundamentally reduced. Moreover, the bridge frame made of steel is not d...

Problems solved by technology

[0002] The existing U-shaped cable trays are usually made of thicker steel in order to meet their load-bearing capacity. Therefore, the produced bridges are heavy in weight, high in transportation and production costs, and labor-intensive for workers during installation. It is also prone to subsidence phenomenon. In order to solve this problem, opening holes on the U-shaped frame to reduce the weight of the bridge frame, or setting metal reinforcement ribs to reduce the thickness of the bridge frame, but this solution is very important for reducing the amount of steel. It doesn't help obviously, and it also complicates the construction of the bridge, and increases the cost of man-hours, so it doesn't fundamentally reduce the cost of the cable tray

Moreover, the bridge frame made entirely of steel is easy to rust due to its long-term exposure to the air, and its durability is not high
