Abstract
The utility model discloses a manhole cover socket made of polymer composite materials. The inner wall of a composite material shell is coated with a high milecular layer, a reinforcing steel ring is placed in the composite material shell, and filling materials are filled in the composite material shell. The composite materials have better impact flexibility and wear resistance such as fiberglass reinforced molding compounds made of unsaturated polyester resins or reinforced polypropylene materials. The manufacturing method can be forged by pressure or shaped by injection. The manhole cover socket made of the polymer composite materials has the advantages of wear resistance, shock resistance, compression resistance, simple manufacturing, service life improvement and low cost.
Description
One, affiliated technical field
The present invention relates to a kind of polymer composite material manhole cover base, refer in particular to glass and strengthen unsaturated polyester resin moulding compound or RPP material composite material manhole cover base.
Two, background technology
Polymer composite material manhole cover is because it is in light weight, no recovery value and more and more be subjected to the favor in market.But since this product also have a lot of shortcomings as: composite material base because of compressive strength and poor impact toughness, roll to carry through road roller and can occur collapsing limit or phenomenon of rupture after executing with vehicle, influenced the application life of complete well lid.
Three, utility model content
The purpose of this utility model provides a kind of polymer composite material manhole cover base, its wear-resisting, shock-resistant and compression.The product manufacturing is simple, improves application life, and with low cost.
For achieving the above object, the solution that the utility model is taked is: a kind of polymer composite material manhole cover base, and the material shell inwall scribbles macromolecule layer, and material shell is put into steel ring and is filled with filler.
Described filler is the mixture of cement, skeleton material, sand, water.
Described filler is the mixture of cement, skeleton material, sand, water, steel fibre.
Shell is that glass strengthens unsaturated polyester resin moulding compound or reinforced polypropylene compound material, the material shell inwall is handled to improve concrete and composite material adhesive strength through molecular layer, and material shell inside is enriched by cement concrete or steel fiber feinforced cement concrete filler.Because composite material has wear-resisting, shock-resistant effect, and filler plays the compressive strength that improves the well seat, makes the upper surface of well seat and bearing surface not collapse the limit phenomenon, has improved product application life.The well seat with test after well lid cooperates, can bear the trial load of 50T and do not ftracture, it is carried out finding that from 3 meters high free falling impact tests the well seats do not rupture or ftracture.The product manufacturing is simple, and with low cost.
Four, description of drawings
The stereogram of Fig. 1 side of being well seat.
Fig. 2 is the cutaway drawing of square well seat shown in Figure 1.
Fig. 3 is a stereogram of using circle well seat.
Fig. 4 is the cutaway drawing of round well seat shown in Figure 3.
Fig. 5 is a B-B sectional drawing among A-A and Fig. 3 among Fig. 1.
Among the figure: 1, material shell, 2, macromolecule layer, 3, steel ring, 4, filler.
Five, the specific embodiment
Below in conjunction with embodiment and accompanying drawing thereof the utility model is remake description.
Referring to Fig. 1～Fig. 5, a kind of polymer composite material manhole cover base, material shell 1 inwall scribbles macromolecule layer 2, and material shell 1 is put into steel ring 3 and is filled with filler 4.
Referring to Fig. 2 and Fig. 4, create material shell 1 by mold pressing or injection molding forming method, see it is a complete well seat from top to bottom, and see it is a kind of hollow thin-wall annulus or square ring type structure from the bottom up.Composite material such as glass strengthen unsaturated polyester resin moulding compound or RPP material, have impact toughness and abrasion resistance preferably.Its manufacture method can be hot moulding or injection mo(u)lding.
