Description
Technical field
The utility model relates to cover plate technical field, especially a kind of double-strength pipe trench cover.
Background technology
On pipeline, irrigation canals and ditches, need adaptive cover plate, common cover plate is generally concrete structure or steel plate, and ordinary concrete is that fragile material, stretch-proof performance and bend resistance poor-performing and unit weight are large.Though it is many that steel concrete improves ordinary concrete defect, concrete produces behind crack, and the easy corrosion of reinforcing bar, unit weight are also large, and especially reinforced concrete member, under the adverse circumstances such as marine corrosion, after corrosion of steel bar, is easily split up concrete component; And reinforcing bar strengthens concrete component and have metal material, easily electromagnetic signal is produced and disturbed.And if adopt chopped strand to strengthen concrete, easily there is agglomeration in chopped strand in concrete substrate, disperses inhomogeneously, and short fiber improves limited to the supporting capacity of concrete component.Steel plate produces and disturbs electromagnetic signal especially, therefore needs a kind of cover plate durable, that can not disturb electromagnetic signal generation.
Utility model content
The technical problems to be solved in the utility model is: overcome cover plate intensity of the prior art not high, poor mechanical property, has the technical problem of electromagnetic interference, a kind of double-strength pipe trench cover is provided, and mechanical property is good, and intensity is large, unit weight is little, can electromagnetic signal not produced and be disturbed.
The utility model solves the technical scheme that its technical problem adopts: a kind of double-strength pipe trench cover, comprise concrete and be built in the skeleton in concrete, described skeleton comprises at least two layers of nonmetal grid beam be arrangeding in parallel and some nonmetal connectors, the two sides up and down at each crossed node place of described nonmetal grid beam are respectively equipped with a connection end, between described neighbouring two-layer nonmetal grid beam, peg graft respectively or a nonmetal connector of socket on the connection end of correspondence.By nonmetal skeleton, play and strengthen concrete effect, and can electromagnetic signal not produced and be disturbed.
Further, according to actual needs, the number of plies of described nonmetal grid beam is 2-5 layer, and nonmetal grid beam consists of pipe or the bar of some horizontally sets and some longitudinal settings.The number of plies of nonmetal grid beam and spacing can design according to actual needs.
The first embodiment, described nonmetal grid beam is glass steelframe and/or carbon fiber frame, described connection end is external thread rod, described nonmetal connector is glass fiber reinforced plastic tube connector and/or carbon fiber tube connector, and the two ends of glass fiber reinforced plastic tube connector and/or carbon fiber tube connector have the internal thread segment of mating with the external screw thread of connection end.Adopt glass fiber reinforced plastic or carbon fiber material can reduce unit weight, can strengthen the bonding strength between nonmetal connector and nonmetal grid beam.
The second embodiment, described nonmetal grid beam is glass steelframe and/or carbon fiber frame, described connection end is riffled tube, described nonmetal connector is glass fiber reinforced plastic connecting rod and/or carbon fiber connecting rod, and the two ends of glass fiber reinforced plastic connecting rod and/or carbon fiber connecting rod have the external thread rod mating with the internal thread of connection end.Adopt glass fiber reinforced plastic or carbon fiber material can reduce unit weight, can strengthen the bonding strength between nonmetal connector and nonmetal grid beam.
The beneficial effects of the utility model are, double-strength pipe trench cover of the present utility model, simple in structure, novel, adopt nonmetal grid beam to replace cage of reinforcement, reduce unit weight, and can improve mechanical property, intensity is high, good toughness, crack resistance are good, corrosion-resistant, can electromagnetic signal not produced and be disturbed.
