Abstract
The present invention discloses a kind of high-strength thermoplastic fibre reinforced composites well lid, includes well lid face and supports the reinforcement in well lid face, the fiber that the fiber in well lid face and anti-skidding boss thereon includes at least one layer of continuous fiber, reinforcement is long fibre.Instant invention overcomes prior art exist it is heavy frangible, vehicle by when the big defect of noise, and existing polymer composite system cellar for storing things well lid presence the low defect of bearing capacity.Continuous fiber complements each other with long fibre, overcomes respective deficiency, enhances the compression strength of well lid, is less prone to crackle.
Description
Technical field
The present invention relates to a kind of road construction component, and in particular to a kind of high-strength thermoplastic fibre reinforced composites well
Lid.
Background technology
For sewer on current road surface, the well lid of buried cable and piped gas well head is generally metal class well lid, this
Plant casting iron well lid heavy, operation labor intensity is big, unsightly, easily gets rusty, and Loss happens occasionally.Every year because well lid lacks
Personal injury, property loss etc. caused by mistake, sedimentation are unexpected to be caused greatly to damage to the country and people's lives and properties, Er Qieche
By when, noise is larger.Although the evil well lid for also having some polymer composites at present occurs, generally existing one
A little defects, such as applying date are on January 15th, 1997, Application No. CN97205777.3 Gonghu triumphant a kind of Manhole cover, Manhole cover
By the nonmetallic composite plate and metal framework or the framework nonmetallic composite plate and metal framework of compacting suppressed
It is compound to be made；The applying date is on July 29th, 1998, and Application No. CN98234752.9 patent discloses a kind of manhole cover, it
It is that, by press polish layer, steel fiber reinforced concrete and weldering net reinforcing bar are constituted, and described steel fiber reinforced concrete is embedded in cement mortar press polish layer
It is interior, weldering net reinforcing bar is also embedded between steel fiber reinforced concrete.Although alleviating the quality of well lid, the metal of the inside mixing
Easily depart from after getting rusty with nonmetallic materials, service life is greatly reduced.2004 applyings date August 10 days, Application No.
200420081583.7 patent discloses a kind of cellar for storing things well lid, including the well lid frame that is made of polymer composite and is arranged on
The bottom surface of frame bottom, along bottom surface thickness direction and perpendicular to bottom surface provided be connected with each other and form one with bottom surface and frame
Composition stress dispersion hole reinforcement cross rib.Although the present invention overcomes the defect got rusty, holding in actual use
Carry power it is smaller, oversize vehicle by when be easily broken.
The content of the invention
The purpose of the present invention is to overcome the deficiencies in the prior art there is provided a kind of high-strength thermoplastic fibre reinforced composites
Well lid.
To achieve the above object, the present invention uses following technical scheme：
A kind of high-strength thermoplastic fibre reinforced composites well lid, includes the reinforcement of well lid face and support well lid face
Muscle, it is characterised in that：Fiber in well lid face and anti-skidding boss thereon includes at least two layers continuous fiber, continuous fiber layer
Between sandwiched long fibre layer between adjacent or continuous fiber layer；Described continuous fiber is that the fiber that thermoplastic resin impregnates is knitted
Thing；Fiber in reinforcement is long fibre；The reinforcement, well lid face are integrally formed；The thermoplastic of the well lid face dipping
Property the thermoplastic resin that impregnates of resin and reinforcement be different resins.
Instant invention overcomes prior art exist it is heavy frangible, vehicle by when the big defect of noise, it is and existing
The low defect of bearing capacity that polymer composite system cellar for storing things well lid is present.Continuous fiber complements each other with long fibre, overcomes each
From deficiency, enhance the compression strength of well lid, be less prone to crackle.
Brief description of the drawings
Fig. 1 is structural representation of the invention.
Fig. 2 is the structural representation of another angle of the invention.
Fig. 3 be Fig. 2 in AA to sectional view.
Embodiment
As shown in Figure 1 and Figure 2, a kind of high-strength thermoplastic fibre reinforced composites well lid, including well lid face 11 and branch
The reinforcement 21 of well lid face is supportted, well lid skeleton, well lid face are integrally formed.In well lid face and anti-skidding boss 12 thereon
Fiber includes between at least two layers continuous fiber, continuous fiber layer sandwiched long fibre layer between adjacent or continuous fiber layer, even
Continuous fiber is the fabric that thermoplastic resin impregnates.The thermoplasticity that the thermoplastic resin of well lid face dipping impregnates with reinforcement
Resin is different resin.Fiber in reinforcement is long fibre, and reinforcement, well lid face are integrally formed.As shown in figure 3, well
Capping and anti-skidding boss thereon are sandwiched long fibre layer 32 between continuous fiber layer 31, continuous fiber layer, support well lid skeleton
Fiber in the reinforcement of bottom is long fibre layer 33.Continuous fiber reinforced thermoplastic plastic is moulded with long fiber reinforcement thermoplasticity
Preparation method for material is similar, and simply continuous fiber reinforced thermoplastic plastic is uninterrupted along its length, can infinitely extend.Long fibre
Reinforced thermoplastics is the strip being sufficiently impregnated by resin that long fibre is obtained after resin dedicated dipping, then according to need
It is cut into the length of needs, generally 20-30cm.
