Abstract
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
The present invention relates to a kind of crane span structure, particularly a kind ofly be used to communicate by letter or the cable testing bridge of engineering such as electric power, belong to the technical field of power circuit equipment.
Background technology
Crane span structure is often used in cable and wire wiring at present, and it is widely used as support body.The obturator that the crane span structure that people generally use is made up of crane span structure main body and cover plate, crane span structure main body and cover plate adopt the machining moulding mostly, when short circuit produces naked light or breaking out of fire, its defective just displays, cable work in crane span structure will be very short, can not guarantee emergency requirement, moreover increase the loss of fire, can not satisfy the requirement of electric fireproof grade.
Summary of the invention
Technical problem to be solved by this invention provides a kind of simple in structure and can fine fire-resistant groove type fire-retardant bridge.
For solving the problems of the technologies described above, the present invention is achieved through the following technical solutions:
A kind of groove type fire-retardant bridge is made of cover plate and crane span structure main body, and cover plate is connected with the crane span structure main body by snap close, it is characterized in that: be provided with inorganic fire rated partition in the inboard of crane span structure main body and cover plate or at the inside and outside fireproof paint that is coated with of described groove type fire-retardant bridge.
As a further improvement on the present invention, the surface of described groove type fire-retardant bridge adds plastic-blasting or hot galvanizing processing through plastic-blasting, electrogalvanizing, electrogalvanizing.
The invention has the advantages that:
1, is provided with inorganic fire rated partition or in the inboard of crane span structure main body and cover plate, improved the fire resistance of crane span structure, the fire resistance period of crane span structure is prolonged, reduce economic loss at the inside and outside fireproof paint that is coated with of described groove type fire-retardant bridge.
2, processing such as groove type fire-retardant bridge surface plastic spraying of the present invention, plating; to decorate protectiveness and various functional superficial layer, can strengthen metal corrosion resistance, increase hardness, prevent abrasion, improve conductivity, lubrification, thermal endurance and surface aesthetic.
Description of drawings
Fig. 1 is the structural representation of groove type fire-retardant bridge of the present invention;
Fig. 2 is the vertical view of the crane span structure main body of groove type fire-retardant bridge of the present invention.
Cover plate 1, crane span structure main body 2, inorganic fire proof material 3 are wherein arranged.
Embodiment
The present invention will be further described in detail below in conjunction with specific embodiment.
As shown in Figure 1, a kind of groove type fire-retardant bridge is made of cover plate 1 and crane span structure main body 2, cover plate 1 and crane span structure main body 2 all can be carried out machining, in order to alleviate its weight by the cutting, roll over, dash of steel plate, reduce material consumption and cost, can adopt 0.8 millimeter steel plate.Cover plate 1 is connected with crane span structure main body 2 by snap close, be provided with inorganic fire rated partition 3 in the inboard of crane span structure main body 2 and cover plate 1 or at the inside and outside fireproof paint that is coated with of described groove type fire-retardant bridge, improved the fire resistance of crane span structure, the fire resistance period prolongation with crane span structure reduces economic loss.
Inorganic fire rated partition 3 is being set, and when taking too many space, can adopt inside and outside sprayed fire proofing coating at groove type fire-retardant bridge, so just can be when guaranteeing fire resistance, reduce the shared space of inorganic fire rated partition 3, can lay more electric wire or cable therein.
Plastic-blasting, electrogalvanizing can be passed through in the surface of groove type fire-retardant bridge, electrogalvanizing adds plastic-blasting or hot galvanizing is handled; thereby to decorate protectiveness and various functional superficial layer, can strengthen metal corrosion resistance, increase hardness, prevent abrasion, improve conductivity, lubrification, thermal endurance and surface aesthetic.
The foregoing description does not limit the present invention in any way, and every employing is equal to replaces or technical scheme that the mode of equivalent transformation obtains all drops in protection scope of the present invention.
Claims (2)
1, a kind of groove type fire-retardant bridge, constitute by cover plate and crane span structure main body, cover plate is connected with the crane span structure main body by snap close, it is characterized in that: be provided with inorganic fire rated partition in the inboard of crane span structure main body and cover plate or at the inside and outside fireproof paint that is coated with of described groove type fire-retardant bridge.
2, groove type fire-retardant bridge according to claim 1 is characterized in that: the surface plastic spraying of described groove type fire-retardant bridge, electrogalvanizing, electrogalvanizing add plastic-blasting or hot galvanizing.
