Abstract
The utility model relates to a glass fiber reinforced plastic cable channel cover plate which adopts a rectangular cancelled structure; an open web of the cover plate is internally provided with longitudinal reinforcing ribs which are distributed uniformly; the upper surface of the cable channel cover plate is provided with concave-convex interphase strip-type antiskid streaks; and the cover plate is the overall structural glass fiber reinforced plastic cable channel cover plate made by pultrusion process. The cover plate has high strength, smooth surface, neat and beautiful appearance, very high corrosion resistant performance of acid-base solution resistance and soaking of gasoline and the like, and ageing resistance, and does not have phenomena of dusting, discoloring, crazing, deformation and the like when being used for ages. When in use, the cover plate is laid on the channel on the top of the cable channel, has very butt seams, greatly reduces rainwater and dust falling into the cable channel, guarantees the safety operation of the cable, prolongs the service life of the cable, also has good insulation performance and fire prevention and flame retardant performance, and can effectively avoid the personnel damage and the damage on the cable caused by lightning strike, electric leakage or fire hazard.
Description
Technical field
The utility model relates to a kind of glass fiber reinforced plastic cable channel cover plate, and it is the protective equipment that a kind of power plant, power transmission and transformation station, subway and traffic tunnel etc. are located the underground cable ditch.
Background technology
At present; the underground cable ditch in places such as power plant, power transmission and transformation station, subway and traffic tunnel; for the protection cable security is carried power supply; avoid sunlight direct projection cable insulation to make it aging; also avoid rainwater, dust, foreign material to fall into cable trough; it is current to be convenient to personnel again, must cover the cable channel cover plate of protective action on cable trough.Used cable channel cover plate generally adopts the cement steel concrete material, and around on the frame angle bar frame make.In recent years begin the cover plate of inorganic compounding shape material on probation again.
The cable channel cover plate of its cement steel concrete material for guaranteeing that certain bearing capacity is arranged, must be made very abundantly, thereby heaviness is not easy to move, is unfavorable for that cable trough safeguards and overhaul; And lid surface is coarse, uneven, and the splicing slit is big; Material is thin crisp simultaneously, and shock resistance is poor, lacks easily and turns arrisdefect.
Though the cover plate of inorganic composite type has overcome most of defective of cement cover board, yet not only to reach three months and cause the production cycle long because of the full solidification time; And bearing capacity is not strong; The while easy deformation, meeting two ends perk after use a period of time, gross distortion needs to change.
Summary of the invention
The purpose of this utility model is to overcome the defective of above two kinds of material products, and a kind of cable channel cover plate of fiberglass reinforced plastics is provided, in order to the cable channel cover plate of place of cement armored concrete and inorganic composite materials.
The technical solution of the utility model: a kind of glass fiber reinforced plastic cable channel cover plate, it is characterized in that this cable channel cover plate is the cable channel cover plate of rectangle cancelled structure, uniform waling is arranged in the empty stomach of its cable channel cover plate, the cable channel cover plate upper surface is provided with the anti-skidding line of the concavo-convex alternate bar shaped of different shape, the spacing of this anti-skidding line is equidistantly or the anti-skidding line of not equidistant bar shaped, the shaped design of anti-skidding line is can rule, also can the anti-skidding line of irregular bar shaped; This cable channel cover plate is the glass fiber reinforced plastic cable channel cover plate of the monolithic construction of pultrusion molding process manufacturing.
This cable channel cover plate, be on forming machine using drawing and extrusion, to make moulding, its technical process be with unsaturated polyester resin, aluminium hydroxide, heavy calcium carbonate, curing agent, release agent and colorant etc. in the ratio of process stipulation be added to stir in the mixer after, in the resin storage tank before the injection molding machine; Woven glass roving fabric on the creel and reinforcing materials such as glass mat, surperficial felt are drawn continuously through the clamping draw-gear of forming machine using drawing and extrusion, make it in resin storage tank, carry out resin impregnation by guiding device; Impregnated reinforcing material passes pre-shaping device, transmits modestly continuously, moves closer to the net shape of goods and extrudes unnecessary resin so that guarantee their relative position; Enter then and heat up in advance and be incubated in the mould of required curing temperature, carry out forming and hardening; The product of depanning curing molding is through cutting into the product of required size continuously.
In sum, this cable channel cover plate intensity height, smooth surface, neat appearance is attractive in appearance; Has the corrosion resistance that very high acid and alkali resistance solution and gasoline etc. soak; Also have very strong ageing resistace, long-term use phenomenons such as efflorescence, variable color, be full of cracks and distortion can not occur.This cover plate is layered on the raceway groove above the cable trough during use, and piece is very little, significantly reduces rainwater, dust, foreign material and falls in the cable trough, and to guaranteeing the safe operation of cable, be very helpful the useful life that prolongs cable.Patented product of the present invention also has good insulation performance performance and fire retardant performance, can effectively avoid personnel's injury of causing because of thunderbolt or electric leakage or fire and to the damage of cable.
Description of drawings
Accompanying drawing is a structural representation of the present utility model.
Embodiment
Referring to accompanying drawing, a kind of glass fiber reinforced plastic cable channel cover plate, it is characterized in that this cable channel cover plate is designed to the cable channel cover plate of rectangle cancelled structure, uniform waling is arranged in the empty stomach of its cable channel cover plate, and the cable channel cover plate upper surface is provided with the concavo-convex alternate anti-skidding line of equidistant bar shaped of different shape (anti-skidding line spacing can be not equidistant yet); This cable channel cover plate is the cable channel cover plate that adopts the fiberglass reinforced plastics monolithic construction of pultrusion molding process manufacturing.
This cover plate is to adopt the fiberglass reinforced plastics pultrusion to make, promptly adopting pultrusion molding process to produce continuously forms through cutting again, during use, this cover plate is moved towards one near on the raceway groove that laterally is layered on side by side above the cable trough by cable trough, one of anti-skidding line is faced up, promptly finish a laying that both construction maintenance is easy easily, attractive in appearance again, durable, anticorrosion, the aging-resistant cable channel cover plate is gone back in insulation.
