Abstract
The utility model discloses a novel rain water grate. Which is composed of a reinforced resin core body which is formed by waste plastics, cinder or quartz sands of different grades and a filler, a reinforced resin casing body which is formed by the glass fiber coated on the outer surface of the core body and, a reinforcing body positioned on the lower part in the core body, and a reinforced resin wear-resistant layer which is formed by sands or stones and glass fiber applied on the upper surface of the casing body, wherein the reinforcing body is formed by concretion of the mixed composite material reinforced resin which is composed of the glass fiber or the glass fiber and the carbon fiber. The rainwater grate with the structural material has the characteristics of high strength, large span length, impact resistance, fatigue resistance, good fracture toughness, practicality, beauty, wear resistance, corrosion resistance, theft protection, easy manufacture, low cost, etc.
Description
Technical field
The utility model relates to a kind of rain grid made in building and the municipal engineering, and is used as draining.
Background technology
What water discharger for road generally adopted at present is the cast iron rain grid made, often stolen, forms life, vehicle safety hidden danger; Easily get rusty simultaneously, not attractive in appearance.The glass fiber reinforced plastic rain grid made has solved stolen problem, but the cost of manufacture height, supporting capacity is low, and toughness is poor, and is easily aging.Concrete rain grid made cost is low, and is antitheft, but supporting capacity is low, and toughness is poor, and easy fracture damages, and the surface is not attractive in appearance.Other reinforced composite material rain grid made supporting capacity height is also arranged, antitheft, but complex manufacturing technology, cost height.They all can not well participate in market competition and satisfy people's demand.
Summary of the invention
The purpose of this utility model provides a kind of shock resistance, and fracture toughness is good, and span is big, and is antitheft, and wear-resisting, corrosion-resistant, simple in structure, cost of manufacture is low, has the high-strength composite material rain grid made that beautifies effect, reduces the fracture damage of rain grid made to greatest extent.
Realize that the technical scheme that the utility model purpose adopts is:
Novel rain grid made is to strengthen resin core by the quartz sand of waste or used plastics and slag or different gradation and filler, be coated on the galss fiber reinforced resin housing of core outer surface, be positioned at the intensive aspect of core body bottom and be coated with sand or stone and the galss fiber reinforced resin wearing layer formation that is layered on the housing upper surface.Intensive aspect is to strengthen hardening of resin by the hybrid composite that glass fiber or glass fiber and carbon fiber constitute to form, and is the continuous fiber thigh that a kind of special device is made, and has ad hoc structure.
The arc-shaped structure design is adopted in the bottom that the utility model has the advantages that rain grid made, and the shape of seemingly intercepting ball increases its thickness, helps the raising of intensity and the making of big span rain grid made.The bottom is provided with intensive aspect in the core body of rain grid made, guarantees the high strength and the shock resistance of rain grid made, and endurance, fracture toughness are good.The pattern of wearing layer and color can design, and be both artistic and practical.Have wear-resistantly, corrosion-resistant simultaneously, make simply, cost of production is low, no recovery value, characteristics such as antitheft.
Description of drawings
Figure of description is the sectional view of the utility model rain grid made embodiment.
The specific embodiment
The utility model is described in further detail below in conjunction with drawings and Examples.
Arc-shaped structure design, the shape of seemingly intercepting ball are adopted in the bottom of rain grid made in the utility model embodiment.Core body 2 is to be reinforcing material by the quartz sand of waste or used plastics and slag or different gradation and filler, resin is a base-material, mix to solidify and form, add brilliant fibre or fiberglas chopped strand where necessary as reinforcing material, the mixture of one or more in filler employing calcium carbonate, dolomite, French chalk, the graphite.Intensive aspect 1 is to strengthen hardening of resin by the hybrid composite that glass fiber or glass fiber and carbon fiber constitute to form, and is the continuous fiber thigh that a kind of special device is made, and has ad hoc structure.Intensive aspect 1 is placed bottoms in the core body to be formed 2, and to coat one deck be reinforcing material with the glass fiber to the external surface of the integral body that constitutes at core body 2 and intensive aspect 1 then, and resin is the concretionary housing 3 of base-material.After having coated housing 3, the upper surface at housing 3 is coated with the wearing layer 4 that shop one deck sand or stone and galss fiber reinforced resin are formed again, and curing molding.When being coated with shop wearing layer 4, can add look and stick with paste according to actual needs, make the rain grid made of different colours, also can improve mould, make the rain grid made that has like beautiful matter embossment, realize personalized designs, meet the needs of different users.
Adopt this kind technology also can produce the high-strength composite material well lid.
In the above-mentioned implementation process, adding resin simultaneously, also process of resin technology routinely adds accelerator, curing compound or initator, again with reinforcing material mixing coagulation forming.
Claims (4)
1. novel rain grid made, it is characterized in that: it strengthens resin core (2) by the quartz sand and the filler of waste or used plastics and slag or different gradation, be coated on the galss fiber reinforced resin housing (3) of core body (2) external surface, be positioned at the intensive aspect (1) of core body (2) bottom and be coated with sand or stone and galss fiber reinforced resin wearing layer (4) formation that is layered on housing (3) upper surface.
2. novel rain grid made according to claim 1 is characterized in that: intensive aspect (1) is to strengthen the continuous fiber thigh that hardening of resin forms by the hybrid composite that glass fiber or glass fiber and carbon fiber constitute.
3. novel rain grid made according to claim 1 is characterized in that: add brilliant fibre or fiberglas chopped strand as reinforcing material in core body (2).
4. novel rain grid made according to claim 1 is characterized in that: the arc-shaped structure design is adopted in the bottom of rain grid made.
