Abstract
The utility model discloses a high strength glass fiber reinforced plastic bridge frame, which comprises a base and a cover plate, wherein the base comprises a base plate and side plates fixed on two sides of the base plate, each side plate is of a double-layer structure, the inner layer of each base plate is a steel structure plate formed with the base plate at one time, at the same time, a layer of glass fiber reinforced plastic is arranged on the outer layer of the side plate, the glass fiber reinforced plastic is connected with the steel structure plate through a fastening bolt; and in addition, sliding slots are arranged on the inner sides at the upper parts of the side plates, and the cover plate is folded into a corresponding bulged batten on the edge in a bending manner. The high strength glass fiber reinforced plastic bridge frame is simple in technology, convenient to process and easy to assemble, and can effectively prevent corrosion and resist compression.
Description
Technical field
The utility model relates to for the distribution field, is specially a kind of high strength glass fiber reinforced plastic crane span structure.
Background technique
In general, crane span structure is as being used for the device of fixed cable for the distribution field, and its application is very extensive.In the operation process of the circuits such as cable laying, netting twine; often can be because the difference of the specification of lay-up, size; adopt the crane span structure of different size to satisfy the demand of laying; simultaneously; in order to improve bulk strength; make crane span structure can be used in environment more abominable place, made a lot of improvement for its structure.But owing to being restricted on size, the thickness of adding sheet metal is limited, for installation requirement and the higher occasion of size requirement, is difficult to satisfy on-the-spot installation requirement at some.
The model utility content
The technical problem that the utility model solves is to provide a kind of high strength glass fiber reinforced plastic crane span structure, to solve the shortcoming in the above-mentioned background technology.
The technical problem that the utility model solves realizes by the following technical solutions:
A kind of high strength glass fiber reinforced plastic crane span structure, comprise pedestal and cover plate, wherein, the side plate that described pedestal comprises base plate and is fixed on the base plate both sides, described side plate is double layer construction, and its internal layer is one and the one-time formed steel structure plate of base plate, simultaneously, include one deck glass fibre reinforced plastics at its skin, be connected by clamping bolt between glass fibre reinforced plastics and steel structure plate; In addition, be provided with chute in the upper inner of side plate, and be bent into corresponding flange bar in described side edge thereof, insert from the side in chute by the flange bar, can realize fixing on pedestal of cover plate.
In the utility model, described chute is that the steel structure plate portion forms in the top bending of picking up the ears.
In the utility model, to be that steel structure is one-body molded make described cover plate.
Beneficial effect: the utility model arranges glass fibre reinforced plastic structure as girth member on the steel structure pedestal, can effectively improve the integrally-built intensity of crane span structure, and be difficult for corrosion, and insulating property are superior, and is convenient to transportation and dismounting.
Description of drawings
Fig. 1 is the schematic diagram of the utility model preferred embodiment.
Embodiment
For technological means, creation characteristic that the utility model is realized, reach purpose and effect is easy to understand, below in conjunction with concrete diagram, further set forth the utility model.
preferred embodiment referring to a kind of high strength glass fiber reinforced plastic crane span structure of Fig. 1, in the present embodiment, crane span structure needs to form several crane span structures unit in build process, each crane span structure unit comprises pedestal 2 and cover plate 1, wherein to be that the steel structure plate is one-body molded make the base plate of pedestal 2, the side side is erected into two blocks of side plates, the side plate internal layer is the steel structure plate that is connected with base plate, and bend out a groove 6 at an upper portion thereof, be used for reinforcing and also be provided with a glass fibre reinforced plastic structure plate 3 in the outside of side plate, be connected by clamping bolt 4 between the steel structure plate of glass fibre reinforced plastic structure plate 3 and side plate internal layer.
Described cover plate 1 is a steel structure plate, and its outer ledge is bent into a flange bar structure 5, and this flange bar structure 5 can be inserted in groove 6 in the side, is used for completing the assembling of crane span structure.
Above demonstration and described basic principle of the present utility model, major character and advantage of the present utility model.The technician of the industry should understand; the utility model is not restricted to the described embodiments; that describes in above-described embodiment and specification just illustrates principle of the present utility model; under the prerequisite that does not break away from the utility model spirit and scope; the utility model also has various changes and modifications, and these changes and improvements all fall in claimed the utility model scope.The claimed scope of the utility model is defined by appending claims and equivalent thereof.
