Problems solved by technology
The bridge commonly used by people is a closed body composed of the main body of the bridge and the cover plate. Most of the main body and the cover plate of the bridge frame are formed by machining. It will be very short and cannot guarantee the emergency needs. Furthermore, it will increase the loss of the fire and cannot meet the requirements of the electrical fire protection level.

Embodiment Construction
[0013] The present invention will be described in further detail below in conjunction with specific embodiments.
[0014] Such as figure 1 As shown, a trough-type refractory bridge is composed of a cover plate 1 and a bridge main body 2. Both the cover plate 1 and the bridge main body 2 can be machined by cutting, folding and punching steel plates. In order to reduce its weight and reduce material consumption and cost, 0.8mm steel plate can be used. The cover plate 1 is connected with the main body of the bridge frame 2 through a lock, and an inorganic fire-resistant partition 3 is arranged on the inner side of the main body 2 of the bridge frame and the cover plate 1, or a fire-resistant coating is sprayed on the inside and outside of the trough-type fire-resistant bridge frame, which improves the safety of the bridge frame. Fire-resistant performance, prolonging the fire-resistant time of the bridge and reducing economic losses.
[0015] When the inorganic fire-resistant p...

The invention discloses a groove type fire-retardant bridge, which consists of a cover plate and a bridge main body, wherein the cover plate is connected with a bridge main body through a lock catch, the inner sides of the bridge main body and the cover plate are provided with inorganic fire-retardant shields or the inside and the outside of the groove type fire-retardant bridge are sprayed with a fire-retardant coating. The surface of the groove type fire-retardant bridge is processed by plastic spraying, electrogalvanizing, the electrogalvanizing together with the plastic spraying, or hot galvanizing. The inner sides of the bridge main body and the cover plate are provided with the inorganic fire-retardant shields or the inside and the outside of the groove type fire-retardant bridge are sprayed with the fire-retardant coating, thus the fire resistance of the bridge is improved, the fire resistance period of the bridge is prolonged, and the economic loss is reduced. Besides, various decorative and protective functional surface layers obtained on the surface of the groove type fire-retardant bridge through the processes of the plastic spraying, the electrogalvanizing and the like can improve the corrosion resistance of metals, increase the hardness, prevent the abrasion and wear, and improve the conductivity, the lubricity, the heat resistance and the beautiful surface appearance.
Description
technical field [0001] The invention relates to a bridge frame, in particular to a cable bridge frame used in communication or electric power projects, and belongs to the technical field of power line equipment. Background technique [0002] At present, bridges are often used for cable and wire wiring, and they have been widely used as supports. The bridge commonly used by people is a closed body composed of the main body of the bridge and the cover plate. Most of the main body and the cover plate of the bridge frame are formed by machining. Will be very short, can not guarantee emergency needs, moreover increases the loss of fire, can not meet the requirement of electrical fire protection level. Contents of the invention [0003] The technical problem to be solved by the present invention is to provide a trough-type refractory bridge with simple structure and good fire resistance. [0004] In order to solve the problems of the technologies described above, the present i...
