Abstract
The utility model relates to a cable bridge, particularly relates to a compound fire and corrosion resistance epoxy resin composite cable bridge. The cable bridge comprises a bridge main body, a bridge cover plate and a bridge bottom plate. The three parts are all of layer structures, and each layer is tightly combined into integral body through die pressing. The major structural layers of the bridge are a protective layer, a fire resisting layer, a corrosion resisting layer, a combined layer, a metal framework layer, a combined layer, a corrosion resisting layer, a fire resisting layer and a protective layer orderly from external side to internal side. The structural layers of the bridge cover plate are a protective layer, a fire resisting layer, a corrosion resisting layer and a protective layer orderly from external side to internal side. The structural layers of the bridge bottom plate are a protective layer, a fire resisting layer, a corrosion resisting layer and a protective layer orderly from internal side to esternal side. The cable bridge has the characteristics of strong fire resistance performance, large useful space, beautiful appearance, high corrosion resistance performance, strong mechanical strength, etc.
Description
Technical field:
The utility model relates to cable testing bridge, particularly a kind of composite epoxy resin composite fireproof anti-corrosion cable crane span structure.
Background technique:
At present the cable testing bridge of using can be divided into two kinds by the structure difference, and a kind of is appearance application fireproof paint at the metallic cable crane span structure, and inside is dosed thermal-protective material and sticked protecting sheet.Its shortcoming is: 1. the adhesion of fireproof paint and metal crane span structure is not strong, very easily comes off in application process, promptly loses original fire-proof function in case come off; 2. the thermal-protective coating of internal layer and protecting sheet are very thick, take the useful space of a large amount of cable testing bridges; 3. fireproof paint is coated with and is contained on the crane span structure outer surface unevenly, makes that the surface roughness of product is very poor, causes this cable testing bridge profile can not reach the requirement that beautifies of engineering construction.Second kind of fireproof bridge frame is to be made by electrodeless glass fibre reinforced plastics; though electrodeless material does not fire; but when ambient temperature reaches more than 300 ℃, will produce gross distortion even collapse; thereby lose original intensity; forfeiture is supported and protective action to inside cable; make cable directly by flame combustion, can not play anti-fire action.In addition, the antiseptic property of above-mentioned two kinds of fireproof bridge frames and mechanical strength are not high, the place use that is not suitable under rugged environment and requires big span to install.
Summary of the invention:
Goal of the invention of the present utility model is intended to solve the disadvantage that above-mentioned cable testing bridge exists, and provides that a kind of fireproof performance is strong, the useful space big, beautiful shape, has the composite epoxy resin composite fireproof anti-corrosion cable crane span structure of antiseptic property and high mechanical properties.
The technological scheme that realizes the foregoing invention purpose is: this cable testing bridge comprises the crane span structure main body; the crane span structure cover plate; the crane span structure base plate; the three is stratiform structure; combine closely by mold pressing between each layer and be integral; this crane span structure agent structure layer is followed successively by protective layer from outside to inside; fire protection layer; anticorrosive coat; binder course; the metal frame layer; binder course; anticorrosive coat; fire protection layer; protective layer; this crane span structure cover plate structure layer is followed successively by protective layer from outside to inside; fire protection layer; anticorrosive coat; protective layer, this crane span structure bottom plate structure layer is followed successively by protective layer from the inside to the outside; fire protection layer; anticorrosive coat; protective layer.
This composite epoxy resin composite fireproof anti-corrosion cable crane span structure that provides according to this case, connect the mold pressing type stratiform structure tight, that matter density is high owing to adopt, and step on the position at frame body and ladder and increased the steel skeleton, therefore make it have the performance characteristics of the following aspects: 1. fireproof performance is strong, can under 600-1000 ℃ the combustion temperature normal indeformable after using 60 minutes, do not collapse, thereby keep original mechanical strength.2. the useful space is big, and is about about 10mm, identical with common composite epoxy resin cable testing bridge behind the crane span structure wall, increased the utilization efficiency of fireproof bridge frame so greatly.3. product design is attractive in appearance, generous, the surface hardness height, and the top layer is not subjected to after the external impacts yielding and come off, and makes this crane span structure can reach more than 30 years working life.4. antiseptic property is strong, and the rotten performance of spinning that composite epoxy resin is superpower makes this crane span structure to use for a long time under various environment, and strong corrosive mediums such as acid, alkali, salt, ammonia are all had good protection effect.5. mechanical strength height, span can be fabricated into more than 6 meters, and high energy reaches 12 meters spans is not had support, is that general fire-proof cable bridge rack is incomparable.
Description of drawings:
Fig. 1 is a structural representation of the present utility model.
Embodiment:
Provide a specific embodiment of the present utility model below in conjunction with accompanying drawing.
The described composite epoxy resin composite fireproof of present embodiment anti-corrosion cable crane span structure is made up of crane span structure main body, crane span structure cover plate, crane span structure base plate three parts, the three is stratiform structure, compressed together between each layer by mould, because of pressure between the inside and outside mould very high, so connect closely matter density height between each layer of crane span structure after the compression moulding.As shown in Figure 1; this crane span structure agent structure layer is followed successively by protective layer 1, fire protection layer 6, anticorrosive coat 4, binder course 8, metal frame layer 3, binder course 9, anticorrosive coat 5, fire protection layer 7, protective layer 2 from outside to inside; this crane span structure cover plate structure layer is followed successively by protective layer 10, fire protection layer 11, anticorrosive coat 12, protective layer 13 from outside to inside, and this crane span structure bottom plate structure layer is followed successively by protective layer 14, fire protection layer 17, anticorrosive coat 16, protective layer 15 from the inside to the outside.
