Abstract
The utility model relates to a light honeycomb sandwich pipe. The pipe wall is composed of an inner lining layer (1), a structure layer (2) and an outer layer surface (3); the inner lining layer (1) is composed of the fiber reinforced plastic; the structure layer (2) is composed of the paper honeycomb or the aluminum honeycomb or the cloth honeycomb core material; the outer surface layer (3) is composed of the fiber reinforced plastic. Compared with the existing glass fiber reinforced plastic sand inclusion pipe, the utility model enhances the mechanical property of the product, reduces the production cost, and greatly reduces the weight of the product.
Description
The utility model relates to a kind of light weight cellular sandwich tube, is applied to the urban water supply and sewerage field.
Existing plumbing tubing mainly contains Cement Concrete pipe, cast iron tube, ductile iron pipe, PVC (UPVC) pipe, steel pipe, glass reinforced plastic sand pipe etc.
The Cement Concrete pipe:, Heavy Weight low because of intensity, construction trouble, resistance to pressure are bad etc., and the big and medium-sized cities feedwater has not re-used the Cement Concrete pipe.Because of its cost is low, main at present as draining.
Cast iron tube: the Ministry of Construction hereinafter bans use of.
Ductile iron pipe: main as feedwater.
Steel pipe:, construction complexity higher because of price, generally under specific condition, use.
PVC (U-PVC) pipe: because of in light weight, cost is not high, popularize rapidly in draining (tubule) field, but because of fragility by force, not ageing-resistant, not withstand voltage, be not suitable for use in feedwater or heavy caliber waste pipe.
Glass reinforced plastic sand pipe: cast, glass fiber reinforced plastic tubes, because of in light weight, multiple characteristics such as intensity is high, corrosion resistant is strong, long service life, easy transportation and installation are just progressively accepted by people, development rapidly, and is on the high side though performance is good, still exists to promote resistance.
The purpose of this utility model is: at Cement Concrete pipe poor performance, and make the high and a kind of performance that can improve glass reinforced plastic sand pipe that proposes of the cost of glass reinforced plastic sand pipe, can reduce the novel tube structure of glass reinforced plastic sand pipe manufacturing cost again.
Major technique of the present utility model is: its tube wall is made up of inside liner, construction layer, external layer, and its construction layer has one or more layers comb core, bonding one deck fiber-reinforced plastic layer between the two-layer comb core.Inside liner, external layer are fiber reinforced plastic.This honeycomb burning into sand structure with through hole type can guarantee to have higher strength and stiffness, has reduced significantly again and has used material, thereby both had preferable performance, and it is low to have cost again, and characteristics such as in light weight are the best substitute products in the plumbing field.
The utility model will be further described below in conjunction with drawings and Examples.
Description of drawings:
Fig. 1 is the structural representation of light weight cellular sandwich tube;
Fig. 2 is that the A-A of figure one is to schematic representation.
Wherein: [1]-inside liner, form by the young reinforced plastic of glass.
[2]-and construction layer, form by paper wasp nest or aluminium honeycomb or glass cloth comb core.
[3]-and external layer, form by fiber reinforced plastic.
Embodiment:
As shown in drawings: a kind of high intensity lightweight honeycomb sandwich tube that is used to feed water, inside liner [1] is made matrix by food level resin, makes reinforcing material with glass fibre and forms, and forms the inner lining material that satisfies hygienic requirements.Cellular material in the bonding through hole type in inside liner outside is made construction layer [2], and this material is paper wasp nest or aluminium honeycomb or glass cloth honeycomb, impregnated with resin and firmization.Make external layer [3] in the construction layer outside, form by glass fiber reinforced plastic.And as required when making outer surface layer, in resin, add color paste toning as required or add antiageing agent to increase working life.The difference of the utility model and existing glass reinforced plastic sand pipe is that construction layer [2] is not with silica sand-resin but use the through hole cellular material, the mechanical property that had both kept original product, reduced production cost of products again, alleviated 30～60% product weight, made construction further convenient.
