Abstract
The invention discloses a high-strength thermo-plastic fiber reinforced composite material well lid. The high-strength thermo-plastic fiber reinforced composite material well lid comprises a well lid surface and a reinforcing rib which is used for supporting the well lid surface; fibers in the well lid surface part and a skid-proof lug boss which is arranged on the well lid surface comprise at least one layer of continuous fiber; the fiber in the reinforcing rib is long fiber. The high-strength thermo-plastic fiber reinforced composite material well lid disclosed by the invention has the advantage of being capable of overcoming the defects that a well lid in the prior art is heavy, fragile and large in noise when a vehicle passes, and the defects that an existing high-molecular composite material-prepared cellar well lid is low in bearing capacity and the like. The continuous fiber and the long fiber supplement each other to overcome their own shortcomings, so that the compressive strength of the well lid is enhanced, and cracks are unlikely to cause.
Description
Technical field
The present invention relates to a kind of road construction component, be specifically related to a kind of high-strength thermoplastic fibre reinforced composites well lid.
Background technology
For sewer on current road surface, the well lid of underground cable and piped gas well head is generally metal species well lid, and this casting iron well lid is heavy, and operation labor intensity is large, unsightly, easily get rusty, and Loss happens occasionally.The personal injury, property loss etc. that cause because of manhole cover loss, sedimentation every year surprisingly cause great infringement to the country and people's lives and properties, and when vehicle passes through, noise is larger.Although also there is the harmful well lid of some polymer composites to occur at present, but some defects of ubiquity, if the applying date is on January 15th, 1997, application number is the triumphant a kind of Manhole cover of CN97205777.3 Gonghu, and Manhole cover is made up of the framework nonmetallic composite plate of the nonmetallic composite plate suppressed and metal sheet skeleton or compacting and metal sheet skeleton compound; The applying date is on July 29th, 1998, application number be CN98234752.9 patent discloses a kind of manhole cover, it is by press polish layer, steel fibrous concrete and weldering net reinforcing bar are formed, described steel fibrous concrete is embedded in cement mortar press polish layer, is also embedded with weldering net reinforcing bar between steel fibrous concrete.Although alleviate the quality of well lid, after the metal rusting of the inside mixing easily and nonmetals depart from, application life declines greatly.August 10 2004 applying date, application number be 200420081583.7 patent discloses a kind of cellar for storing things well lid, comprise the well lid frame that polymer composite makes and the bottom surface be arranged on bottom frame, along bottom surface thickness direction and be provided with perpendicular to bottom surface and be interconnected and form the reinforcement cross rib in stress dispersion hole with bottom surface and frame shape all-in-one-piece.Although the present invention overcomes the defect of getting rusty, the bearing capacity in actual use procedure is less, oversize vehicle by time easily rupture.
Summary of the invention
The object of the invention is to overcome the deficiencies in the prior art, a kind of high-strength thermoplastic fibre reinforced composites well lid is provided.
For achieving the above object, the present invention is by the following technical solutions:
A kind of high-strength thermoplastic fibre reinforced composites well lid, comprises well lid face and supports the reinforcing rib in well lid face, well lid face and on anti-skidding boss in fiber comprise at least one deck continuous fiber, the fiber in reinforcing rib is long fibre.
Described continuous fiber is one deck.
Described continuous fiber is at least two-layer, sandwiched long fibre layer between adjacent or continuous fiber layer between continuous fiber layer.
Described continuous fiber is thermoplastic resin impregnated continuous unidirectional fibre, the two-way fiber of intersection laying, or at least one in fabric.
Described reinforcing rib, well lid face are one-body molded.
The thermoplastic resin that the thermoplastic resin of described well lid face dipping and reinforcing rib flood is same resin.
The thermoplastic resin that the thermoplastic resin of described well lid face dipping and reinforcing rib flood is different resins.
The heaviness that instant invention overcomes prior art existence is frangible, the defect that when vehicle passes through, noise is large, and existing polymer composite system stores the defects such as the low bearing capacity of well lid existence.Continuous fiber and long fibre complement each other, and overcome respective deficiency, enhance the compressive strength of well lid, not easily occur crackle.
Accompanying drawing explanation
Fig. 1 is structural representation of the present invention.
Fig. 2 is the structural representation of another angle of the present invention.
Fig. 3 be in Fig. 2 AA to sectional view.
Detailed description of the invention
As shown in Figure 1 and Figure 2, a kind of high-strength thermoplastic fibre reinforced composites well lid, comprises well lid face 11 and supports the reinforcing rib 21 in well lid face, and well lid skeleton, well lid face are one-body molded.Well lid face and on anti-skidding boss 12 in fiber comprise at least one deck continuous fiber, when being at least two-layer, sandwiched long fibre layer between adjacent or continuous fiber layer between continuous fiber layer, continuous fiber is thermoplastic resin impregnated continuous unidirectional fibre, the two-way fiber of intersection laying, or at least one in fabric.The thermoplastic resin that the thermoplastic resin of well lid face dipping and reinforcing rib flood is identical or different resin.Fiber in reinforcing rib is long fibre.As shown in Figure 3, well lid face and on anti-skidding boss be continuous fiber layer 31, sandwiched long fibre layer 32 between continuous fiber layer, the fiber supported in the reinforcing rib bottom well lid skeleton is long fibre layer 33.Continuous fiber reinforced thermoplastic plastic is similar to Long-fiber-reinforced thermoplastics preparation method, and just continuous fiber reinforced thermoplastic plastic is uninterrupted along its length, can infinitely extend.Long-fiber-reinforced thermoplastics is the rectangular of fully being flooded by resin of obtaining after resin dedicated dipping of long fibre, is then cut into the length of needs as required, is generally 20-30cm.
