Abstract
The utility model provides an examination well lid reinforced by novel fiber reinforced composite materials, which is composed of a well lid, a well base and reinforcing ribs and is characterized in that the well lid and the well base are compositely formed by matching organic resin, chopped glass fiber, filling materials, and the like with various kinds of additive (thickening agent, firming agent, polymerization inhibitor, internal releasing agent, and the like), the well base is in a sagging gridding shape, the reinforcing ribs are arranged in the well base, and the reinforcing ribs adopt novel fiber as reinforcing materials. The examination well lid adopts specialized novel fiber as the reinforcing materials, and the novel fiber has good affinity with the organic resin to be perfectly combined with the organic resin. The examination well lid reinforced by novel fiber reinforced composite materials still has good integrity when repeatedly rolled by cars, and has high bearing capacity as well as long service life.
Description
Technical field:
The utility model relates to a kind of advanced fiber reinforced composites manhole cover, is mainly used in to be installed on road, highway and other is motor-driven or bicycle may travel or park the ground.
Background technology:
At present, known manhole cover made of composite material all adopts regenerating resin or unsaturated polyester resin to add other composition through casting or compression molding, and selects for use the reinforcing bar of certain specification to do reinforcing material, improves the supporting capacity of composite drain cover.But reinforcing bar is different because of the coefficient of expansion with composite material (regenerating resin, unsaturated polyester resin etc.), two kinds of material interfaces form stress under different temperatures, add rolling repeatedly of vehicular traffic, reinforcing bar is produced with composite material to be separated, cause manhole cover made of composite material to lose globality, reduce supporting capacity, caused accident potential, and finally lost use value.
Summary of the invention:
In order to overcome the deficiency that existing manhole cover made of composite material supporting capacity is low and application life is short, the manhole cover that the utility model provides a kind of advanced fiber reinforced composites to strengthen, this advanced fiber reinforced composites manhole cover, still have good globality, not only supporting capacity height but also long service life down rolling repeatedly of vehicular traffic.
The utility model solve its technical problem practical technical scheme be: it is by lid, the lid end and reinforcing rib are formed, it is characterized in that: the described lid and the lid end are by organic resin, short glass fiber and filler etc. are equipped with various additive (thickeners, curing compound, polymerization inhibitor, inner pattern releasing agent applicable etc.) machine-processed composite molding, the lid end is that droop is latticed, inside at the lid end is provided with reinforcing rib, reinforcing rib is done reinforcing material by tencel, use special equipment and moulding means, material is made design shape on mould, apply certain pressure then, by the special tencel reinforcing material of resin impregnated, solidify and maintenance under specified temp, finally demould processes postmenstruation.
The beneficial effects of the utility model are: adopt special tencel to do reinforcing material, this tencel and organic resin have good close vigor, can ideally combine, it is different because of the coefficient of expansion with composite material to stop reinforcing bar fully, and cause the manhole cover made of composite material globality to be destroyed, and reduced supporting capacity, caused accident potential, the phenomenon of forfeiture use value, therefore can substitute other manhole cover made of composite material is applied to various occasions.
Description of drawings:
Fig. 1: be the constructional drawing of a kind of advanced fiber reinforced composites manhole cover of the utility model
Wherein: the lid 1 lid ends 3 reinforcing rib 2
The specific embodiment:
Below in conjunction with the drawings and specific embodiments, the utility model is described in further detail.The utility model is not limited to following examples.
With reference to accompanying drawing, the utility model is by lid 1, the lid end 3 and reinforcing rib 2 are formed, it is characterized in that: the described lid 1 and the lid end 3 are by organic resin, short glass fiber and filler etc. are equipped with various additive (thickeners, curing compound, polymerization inhibitor, inner pattern releasing agent applicable etc.) machine-processed composite molding, the lid end 3 is that droop is latticed, inside at the lid end is provided with reinforcing rib 2, reinforcing rib 2 is done reinforcing material by tencel, use special equipment and moulding means, material is made design shape on mould, apply certain pressure then, by the special tencel reinforcing material of resin impregnated, under specified temp, solidify and maintenance, finally demould processes postmenstruation.
