Abstract
The invention provides a manufacturing method of a glass fiber reinforced plastic cover plate used for a power cable tunnel and belongs to the field of mechanical components. The method includes the steps that a glass fiber reinforced plastic plate is produced through a conventional glass fiber reinforced plastic production technology, and a layer of aluminum alloy cellular board is arranged between at least two layers of glass fiber reinforced plastic; the meshing size of the aluminum alloy cellular board is 20 mm in the direction of length and width, and the meshing size of the aluminum alloy cellular board is 5 mm in the direction of thickness; the thickness of the glass fiber reinforced plastic layers and the thickness of the aluminum alloy cellular board each account for 50%, glass fiber reinforced plastic is arranged on the outer layer, and the aluminum alloy cellular board is arranged on the inner layer; the load bearing strength of the cover plate used for the power cable tunnel is improved through an aluminum alloy enhancement layer, the special requirement of the cover plate used for the power cable tunnel is met through the low weight, the good insulation performance and the excellent corrosion resistance of the glass fiber reinforced plastic, and the requirements in actual work can be totally met.
Description
Technical field
The invention belongs to mechanical component field, particularly relate to a kind of preparation of the cover plate for power cable tunnel.
Background technology
In electric power tunnel construction, need installing cables support in the tunnel of 2 meters high, need installation frame in construction, just need to arrange cover plate.
It is large that described cover plate has width usually, the feature that length is long, and a single cover plate has 2 × 3 meters or larger area usually.
Original employing steel plate makees described panel, although it meets the requirement of intensity, because the weight of its monolithic cover plate is too heavy, is not easy to transport, places and maintenance.
In real work, in the urgent need to use with armor plate strength quite but the material of lighter in weight this substitute existing steel plate and make described cover plate, and need that there is good insulating properties and corrosion resistance.
Applicant once have selected glass fiber reinforced plastic and tries out in numerous material, but will reach the intensity of steel plate, must increase the thickness of glass epoxy, and increases the glass epoxy after thickness and do not reach in weight and require that.
In real work, how to meet the requirement of power cable tunnel cover plate in weight, intensity, weight, developing and a kind ofly have light, high strength, good insulation preformance and the good power cable tunnel cover plate of decay resistance, is a very urgent job.
Summary of the invention
Technical problem to be solved by this invention is to provide a kind of preparation method of power cable tunnel fibreglass reinforced plastic cover, it is provided with enhancement layer in glass fiber reinforced plastic, utilize enhancement layer to improve the load bearing stength of power cable tunnel cover plate, utilize lightweight, the good insulation preformance of glass fiber reinforced plastic and the good special requirement meeting power cable tunnel cover plate of decay resistance, the needs in real work can be met completely.
Technical scheme of the present invention is: the preparation method providing a kind of power cable tunnel fibreglass reinforced plastic cover, comprises and adopts conventional glass fiber reinforced plastic production technology to produce glass epoxy, it is characterized in that:
At least between layer glass steel, one deck aluminum alloy honeycomb plate is set;
The size of mesh opening of described aluminum alloy honeycomb plate in length and width direction is 20mm, and the size of mesh opening of thickness direction is 5mm;
The thickness of the frp layer described in it and the thickness of described aluminum alloy honeycomb plate respectively account for 50%, and glass fiber reinforced plastic is at skin, and cellular board is at internal layer;
Described aluminum alloy honeycomb plate plays load-bearing and ensures the effect of cover board body rigidity;
Described frp layer plays and alleviates cover plate weight, provides good insulating properties and the effect of decay resistance.
Frp layer described in it is at least 10 layers.
The maximum length travel of fibreglass reinforced plastic cover described in it is less than 10mm, and maximum equivalent is 28.5MPa.
The material volume accounting of the frp layer described in it is higher than 50%.
Compared with the prior art, advantage of the present invention is:
Adopt the structure of composite construction board, its frp layer plays and alleviates cover plate weight, provides good insulating properties and the effect of decay resistance, and the aluminum alloy honeycomb plate described in it plays load-bearing and ensures the effect of cover board body rigidity.
Accompanying drawing explanation
Fig. 1 is composite plate structure schematic diagram of the present invention.
In figure, 1 and 2 is frp layer, and 3 is aluminum alloy honeycomb plate.
Detailed description of the invention
Below in conjunction with drawings and Examples, the present invention will be further described.
In Fig. 1, technical scheme of the present invention provides a kind of preparation method of power cable tunnel fibreglass reinforced plastic cover, and comprise and adopt conventional glass fiber reinforced plastic production technology to produce glass epoxy, its inventive point is:
At least between layer glass steel 1 and 2, one deck aluminum alloy honeycomb plate 3 is set;
The size of mesh opening of described aluminum alloy honeycomb plate in length and width direction is 20mm, and the size of mesh opening of thickness direction is 5mm;
The thickness of the frp layer described in it and the thickness of described aluminum alloy honeycomb plate respectively account for 50%, and glass fiber reinforced plastic is at skin, and cellular board is at internal layer;
Described aluminum alloy honeycomb plate plays load-bearing and ensures the effect of cover board body rigidity;
Described frp layer plays and alleviates cover plate weight, provides good insulating properties and the effect of decay resistance.
Frp layer described in it is at least 10 layers.
The maximum length travel of fibreglass reinforced plastic cover described in it is less than 10mm, and maximum equivalent is 28.5MPa.
