Abstract
The utility model relates to for field of power distribution, a kind of fire-resistant trough type bridge frame specifically, comprise base plate and biside plate, described base plate both sides form a dovetail groove along its length respectively, side plate lower end described in each is provided with the boss coordinated with corresponding described dovetail groove, and two boss snap in the dovetail groove of corresponding side plate respectively; Described biside plate and base plate are provided with one deck thermal-protective coating, on the upside of biside plate, are coated with a protecting cover.The utility model adopts the side plate of band boss to coordinate with the base plate of band dovetail groove, 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 protecting cover, makes crane span structure inside form airtight space, Mars etc. can be stoped to enter inner space and destroy cable, improve fireproof performance.
Description
Technical field
The utility model relates to for field of power distribution, is specially a kind of fire-resistant trough type bridge frame.
Background technique
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 sheet metal, at some for installation requirement and the higher occasion of size requirement, be difficult to meet in-site installation requirement, and fireproof performance be not high.
Model utility content
For above-mentioned technical problem, the utility model provides a kind of easy for installation, the fire-resistant trough type bridge frame that fireproof performance is higher.
The utility model solves the problems of the technologies described above adopted technological scheme: a kind of fire-resistant trough type bridge frame, comprise base plate and biside plate, described base plate both sides form a dovetail groove along its length respectively, side plate lower end described in each is provided with the boss coordinated with corresponding described dovetail groove, and two boss snap in the dovetail groove of corresponding side plate respectively; Described biside plate and base plate are provided with one deck thermal-protective coating, on the upside of biside plate, are coated with a protecting cover.
As preferably, on the upside of side plate described in each, bent outward is converted into flange, and described protecting cover both sides are resisted against outside two flange respectively.
As preferably, described base plate is provided with several stiffening rib.
As can be known from the above technical solutions, the utility model adopts the side plate of band boss to coordinate with the base plate of band dovetail groove, 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 protecting cover, makes crane span structure inside form airtight space, Mars etc. can be stoped to enter inner space and destroy cable, improve fireproof performance.
Accompanying drawing explanation
Fig. 1 is the structural representation of a kind of optimal way of the utility model.
Embodiment
Below in conjunction with Fig. 1, the utility model is further described:
A kind of fire-resistant trough type bridge frame, it comprises base plate 1 and biside plate 2, described base plate both sides form a dovetail groove 11 along its length respectively, side plate lower end described in each is provided with the boss 21 coordinated with corresponding described dovetail groove, two boss snap in the dovetail 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-protective coating 3, on the upside of biside plate, are coated with a protecting cover 4, make crane span structure inside form airtight space, Mars etc. can be stoped to enter inner space and destroy cable, improve fireproof performance.
In implementation process, 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 using process on the other hand; Described protecting cover both sides are resisted against outside two flange respectively, improve sealability; Described base plate is provided with several stiffening rib 12, increases the intensity of base plate.
When mounted, just the boss of side plate inserts the other end from one end of base plate dovetail groove, then another side plate of insertion that uses the same method, and this structure not only cost is low, and is connected firmly, convenient and swift.
Above-mentioned mode of execution 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 technological schemes also should belong to category of the present utility model.
Claims (3)
1. a fire-resistant trough type bridge frame, comprise base plate and biside plate, it is characterized in that: described base plate both sides form a dovetail groove along its length respectively, side plate lower end described in each is provided with the boss coordinated with corresponding described dovetail groove, and two boss snap in the dovetail groove of corresponding side plate respectively; Described biside plate and base plate are provided with one deck thermal-protective coating, on the upside of biside plate, are coated with a protecting cover.
2. fire-resistant trough type bridge frame as claimed in claim 1, is characterized in that: on the upside of side plate described in each, bent outward is converted into flange, and described protecting cover both sides are resisted against outside two flange respectively.
