Description

Technical Field

[0001] The utility model belongs to the technical field of fireproof bridge frames, and more specifically, particularly relates to a combined double-layer fireproof bridge frame. Background Art

[0002] Fireproof bridge is a common bridge with a layer of fireproof paint or fireproof coating sprayed on its surface. The surface has a frosted feel to prevent fire and flame retardant effects. It can effectively prevent fire from burning equipment. It is divided into trough type bridge, tray type bridge and ladder type bridge.

[0003] The trough-type fireproof cable tray is a fully enclosed cable tray, which is most suitable for laying computer cables, communication cables, thermocouple cables and control cables of other highly sensitive systems. It has good effects on shielding interference of control cables and protecting cables in heavy corrosion environments. However, the current trough-type fireproof cable tray is usually a single-layer cable tray structure with limited fireproof performance. When a fire occurs indoors with a large amount of flammable materials, the temperature of the single-layer fireproof cable tray will rapidly reach its peak due to the large fire, which will cause damage to the cables.

[0004] Therefore, in view of this, the existing structure and defects are studied and improved, and a combined double-layer fireproof bridge is provided to achieve a more practical purpose. Utility Model Content
