Abstract
The utility model belongs to transmission and distribution equipment, which relates to a ladder-type cable bridge structure, in particular to a fire escape ladder-type cable bridge. The fire escape ladder-type cable bridge comprises a shell composed of side plates and a ladder-type base girder. A flame screen is lined on the base girder, which is in a metal grid structure. Expanding fireproof coating is coated on the surface of the wires forming the metal grids. The flame screen coated with expanding fireproof coating is added based on the prior ladder-type cable bridge structure, thus keeping high thermal diffusivity, high flame retardance and fireproofness as the grids of the flame screen can be closed quickly in case of fire.
Description
Technical field
The utility model belongs to equipment for power transmission and distribution, relates to the structure of ladder-type cable bridge, specifically is a kind of fire prevention ladder-type cable bridge.
Background technology
Common cable testing bridge generally is divided into slot type crane span structure and ladder type crane span structure, and the ladder type crane span structure generally comprises side plate and is connected between the biside plate and the bottom girder of the ladder type that longitudinal separation is provided with, and upper cover plate can also be set as requested.That the advantage of ladder type cable bridge is is in light weight, thermal diffusivity good, but its shortcoming is and can not prevents fires.
Summary of the invention
Technical problem to be solved in the utility model is that the fire prevention that a kind of thermal diffusivity is good, the fire-retardant fireproof ability is strong ladder-type cable bridge is provided.
Fire prevention ladder-type cable bridge of the present utility model includes the housing of being made up of the bottom girder of side plate and ladder type, is lined with one deck flame screen on bottom girder, and described flame screen is the metal grill structure, scribbles expanding fire-proof paint on the metal wire surface that constitutes grid.Cover plate can also be stamped in the top of described side plate.Described expanding fire-proof paint be a class of the prior art can expanded by heating the fireproof paint of foaming.The area of the single grid of described flame screen can be according to fireproof paint expanded by heating rate at 10～20mm
2Select.
The utility model has increased the flame screen that scribbles expanding fire-proof paint on the architecture basics of original ladder-type cable bridge, both can keep better thermal diffusivity, when it meets fire, can seal the grid of flame screen rapidly simultaneously, thereby have good fire-retardant fireproof ability.
Description of drawings
Fig. 1 is the structural representation of the utility model embodiment;
Fig. 2 is the decomposition texture schematic diagram of the utility model embodiment.
Embodiment
As shown in the figure, this crane span structure includes and the bottom girder 2 of the side plate 1 of common ladder-type cable bridge structural similarity, ladder type and cover plate 3 etc., it is characterized in that, is lined with one deck flame screen 4 on bottom girder, the matrix of flame screen is the metal grill structure, scribbles expanding fire-proof paint on the metal wire surface that constitutes grid.Grid 41 requirements of flame screen can be closed after fireproof paint expands, the general 10～20mm that selects of single grid area
