Abstract
The utility model relates to for field of power distribution, be a kind of fireproof bridge frame specifically, it comprises base plate and biside plate, inwardly forms draw-in groove along its length on the downside of side plate described in each, described base plate both sides are respectively arranged with grab downwards, and two grabs snap in the draw-in groove of corresponding side plate respectively; Described biside plate and base plate are provided with one deck thermal insulation layer, on the upside of biside plate, are coated with a protective cover.The utility model adopts the side plate of band draw-in groove to coordinate with the base plate of band grab, and make base plate carry out detachable connection with side plate, it is not only easy for installation, and structure is simpler; Meanwhile, this programme, by the design of heat insulation layer and protective cover, makes crane span structure inside form airtight space, Mars etc. can be stoped to enter inner space and destroy cable, improve fire protecting performance.
Description
Technical field
The utility model relates to for field of power distribution, is specially a kind of fireproof bridge frame.
Background technology
In general, crane span structure is as the device being used for fixed cable for field of power distribution, and its application widely.In the operation process of the circuit such as cable laying, netting twine, often can, because the specification of lay-up, the difference of size, the crane span structure of different size be adopted to meet the demand of laying; Meanwhile, in order to improve bulk strength, making crane span structure can be used in the more severe place of environment, having made a lot of improvement for its structure.But, due to size being restricted, add the finite thickness of metallic plate, at some for installation requirement and the higher occasion of dimensional requirement, be difficult to meet in-site installation requirement, and fire protecting performance be not high.
Utility model content
For above-mentioned technical problem, the utility model provides a kind of easy for installation, the fireproof bridge frame that fire protecting performance is higher.
The utility model solves the problems of the technologies described above adopted technical scheme: a kind of fireproof bridge frame, comprise base plate and biside plate, inwardly draw-in groove is formed along its length on the downside of side plate described in each, described base plate both sides are respectively arranged with grab downwards, and two grabs snap in the draw-in groove of corresponding side plate respectively; Described biside plate and base plate are provided with one deck thermal insulation layer, on the upside of biside plate, are coated with a protective cover.
As preferably, described base plate two ends are bent into rib downwards respectively.
As preferably, on the upside of side plate described in each, bent outward is converted into flange, and described protective cover both sides are resisted against outside two flange respectively.
As preferably, described base plate is provided with several reinforcement.
As can be known from the above technical solutions, the utility model adopts the side plate of band draw-in groove to coordinate with the base plate of band grab, and make base plate carry out detachable connection with side plate, it is not only easy for installation, and structure is simpler; Meanwhile, this programme, by the design of heat insulation layer and protective cover, makes crane span structure inside form airtight space, Mars etc. can be stoped to enter inner space and destroy cable, improve fire protecting performance.
Accompanying drawing explanation
Fig. 1 is the structural representation of a kind of optimal way of the utility model.
Fig. 2 is the preferred cutaway view of base plate in the utility model.
Embodiment
Below in conjunction with Fig. 1, Fig. 2, the utility model is further described:
A kind of fireproof bridge frame, it comprises base plate 1 and biside plate 2, draw-in groove 21 is inwardly formed along its length on the downside of side plate described in each, described base plate both sides are respectively arranged with grab 11 downwards, two grabs snap in the draw-in groove of corresponding side plate respectively, thus making base plate and side plate form detachable connection, it is easy for installation, quick; Described biside plate and base plate are provided with one deck thermal insulation layer 3, on the upside of biside plate, are coated with a protective cover 4, make crane span structure inside form airtight space, Mars etc. can be stoped to enter inner space and destroy cable, improve fire protecting performance.
In implementation process, described base plate two ends are bent into rib 12 downwards respectively, can prevent base plate from sliding along its length; On the upside of side plate 2 described in each, bent outward is converted into flange 22, can increase the intensity of side plate on the one hand, can prevent from scratching cable in use procedure on the other hand; Described protective cover both sides are resisted against outside two flange respectively, improve sealing property; Described base plate is provided with several reinforcement 13, increases the intensity of base plate.
When mounted, can first biside plate be fixed, more from top to bottom to mounting base on side plate, until the grab of side plate snaps in corresponding draw-in groove, two ribs keep out the two ends at side plate simultaneously; Also a side plate first can be installed, then the side grab of base plate is snapped in the draw-in groove of this side plate; Then from bottom to top the draw-in groove of another side plate is inserted in grab, finally protective cover is covered on biside plate.The utility model is flexible for installation, convenient.
Above-mentioned execution mode is only for illustration of the utility model, and be not to restriction of the present utility model, the those of ordinary skill of relevant technical field, when not departing from the utility model spirit and scope, can also make various change and modification, therefore all equivalent technical schemes also should belong to category of the present utility model.
