Abstract
The utility model discloses a plastic slot type bridge frame with the shielding function. A left side plate and a right side plate are buckled on the two side edges of a bottom plate of the bridge frame; cover plates are buckled at the upper edges of the left side plate and the right side plate; and metal layers are respectively arranged on the inner surfaces of the bottom plate, the left side plate, the right side plate and the cover plates. The metal layers arranged on the inner surfaces of buckling plates can play the role of electromagnetic shielding, so as to prevent electromagnetic interference to communication cables laid in the metal layers. Therefore, with low improvement cost, the popularization and application of the plastic slot type bridge frame are greatly convenient. Moreover, the plastic slot type bridge frame has the characteristics of simple structure, reasonable design and the like.
Description
Technical field
The utility model relates to a kind of slot type crane span structure, specifically relates to a kind of plastics slot type crane span structure with function of shielding.
Background technique
In the prior art, plastics slot type crane span structure is owing in light weight, durable, ingenious being widely applied in places such as highway, subway, railway and bridges of design, existing plastics crane span structure is in use because of masking the interference of external electromagnetic ripple, using scope is restricted, and has restricted further applying of plastics slot type crane span structure.
Summary of the invention
The utility model mainly is to solve above-mentioned existing in prior technology technical problem, and a kind of plastics slot type crane span structure with function of shielding is provided.
Above-mentioned technical problem of the present utility model is mainly solved by following technical proposals: a kind of plastics slot type crane span structure with function of shielding, fasten left sideboard and right sideboard on the base plate dual-side of crane span structure, the top of left sideboard and right sideboard fastens cover plate, and the internal surface of described base plate, left sideboard, right sideboard and cover plate is equipped with the layer of metal layer.
As preferably, metal layer on the described plate inner surface extends to the buckling part of base plate and left side plate respectively, metal layer on the described left sideboard internal surface extends to the buckling part of left sideboard and base plate and left sideboard and cover plate respectively, metal layer on the described right sideboard internal surface extends to the buckling part of right sideboard and base plate and right sideboard and cover plate respectively, and the metal layer on the described cover inner surface extends to the buckling part of cover plate and left side plate respectively.
As preferably, described metal layer is made of the metallic film that sprays on the internal surface of base plate, left sideboard, right sideboard and cover plate, perhaps constitute, perhaps constitute by the wire netting of on the internal surface of base plate, left sideboard, right sideboard and cover plate, pasting by the metallic film of on the internal surface of base plate, left sideboard, right sideboard and cover plate, pasting.
The utility model is provided with metal layer at the internal surface of each buckling plate of plastics slot type crane span structure, can play the effect of electromagnetic shielding, and the communication cable of avoiding laying within it suffers electromagnetic interference.Such improvement cost increases few, but greatly facilitates applying of plastics slot type crane span structure, has characteristics such as simple in structure, reasonable in design.
Description of drawings
Fig. 1 is a kind of structural representation of the present utility model.
Embodiment
Below by embodiment, and in conjunction with the accompanying drawings, the technical solution of the utility model is described in further detail.
Embodiment: referring to Fig. 1, fasten left sideboard 1 and right sideboard 2 on base plate 3 dual-sides of the utility model crane span structure, the top of left sideboard 1 and right sideboard 2 fastens cover plate 4, and the internal surface of base plate 3, left sideboard 1, right sideboard 2 and cover plate 4 is equipped with layer of metal layer 5.Wherein the metal layer on the plate inner surface extends to the buckling part of base plate and left side plate respectively, metal layer on the left sideboard internal surface extends to the buckling part of left sideboard and base plate and left sideboard and cover plate respectively, metal layer on the right sideboard internal surface extends to the buckling part of right sideboard and base plate and right sideboard and cover plate respectively, metal layer on the cover inner surface extends to the buckling part of cover plate and left side plate respectively, the metal layer that fastens like this on each buckling plate internal surface of back can mutual conduction, has increased the effect of electromagnetic shielding especially.Metal layer can be made of the metallic film that sprays on the internal surface of base plate, left sideboard, right sideboard and cover plate, also can constitute, perhaps constitute by the wire netting of on the internal surface of base plate, left sideboard, right sideboard and cover plate, pasting by the metallic film of on the internal surface of base plate, left sideboard, right sideboard and cover plate, pasting.
At last, should be pointed out that above embodiment only is the more representational example of the utility model.Obviously, the utility model is not limited to the foregoing description, and many distortion can also be arranged.Every foundation technical spirit of the present utility model all should be thought to belong to protection domain of the present utility model to any simple modification, equivalent variations and modification that above embodiment did.
