Abstract
The utility model relates to a water grate, in particular to a polyacrylonitrile fibre concrete rainwater grate. The ordinary rainwater grates are divided into cast iron rainwater grates, ordinary concrete rainwater grates and the like according to adopted materials. A grate body of the existing ordinary concrete rainwater grate comprises a plurality of grate holes and grate ribs, is difficult to move and has large weight, and is easy to cause brittle damage, so the grate disclosed by the utility model is improved, each grate rib of the rainwater grate is decomposed and formed independently, and the grate ribs are combined when in use. Because the rainwater grate is made of polyacrylonitrile fibre instead of steel bars, each grate rib is formed independently, and the polyacrylonitrile fibre concrete rainwater grate is easier to manufacture, saves steels, has low cost, is easy to move, and avoids being lost.
Description
Technical field
The utility model relates to the rain grid made of municipal engineering, specifically is a kind of concrete of poly-acrylonitrile fiber rain grid made.
Background technology
Common rain grid made has cast iron rain grid made, concrete rain grid made etc. according to the difference of material therefor, is mainly used in swimming pool, the dining room, and road, the sub-district, gutter drainings such as garage are used.Outdoor cast iron rain grid made cost of manufacture height is lost easily and is damaged; The ordinary concrete rain grid made needs cage of reinforcement, makes to bother, and thickness reaches from great, and each rain grid made comprises some grates hole and grate rib, moves difficulty, is easy to generate crack and damage.Annual government will change and keep in repair rain grid made with lot of manpower and material resources.
Summary of the invention
The beneficial effect that the utility model produces is to comprise some grates hole and grate rib at existing ordinary concrete rain grid made, move difficulty, weight is big, be easy to generate the phenomenon that fragility damages has carried out effective improvement, and the grate rib of each rain grid made grate body is decomposed the independent moulding of each grate rib.This rain grid made uses polyacrylonitrile fibre to replace cage of reinforcement in the ordinary concrete rain grid made, so making is simpler, saves steel, avoids simultaneously losing.
The technical solution adopted in the utility model is, with the independent moulding of grate rib of each rain grid made grate body.Adopt the match ratio requirement according to the ordinary concrete rain grid made such as cement, sand, rubble, water, Admixture, the super-high molecular weight polyacrylonitrile fibrous material of admixture certain proportion and length replaces cage of reinforcement in concrete in addition, concrete grade is not less than C30, and the moulding of vibrating gets final product through mould machinery after the stirring.Each concrete rain grid made is made up by several independent grate ribs, and the grate rib is divided into two kinds in C shape limit rib and I shape middle rib, can be combined into the rain grid made that needs length arbitrarily.

1.C shape limit rib, 2.I shape middle rib, 3.I shape middle rib, 4.I shape middle rib, 5.C shape limit rib, 6. grate hole.
The specific embodiment
When rain grid made is installed, the grate rib of independent moulding is made up, be embedded on the rain grid made grate groove of drainage groove, each rain grid made is made up of two C shape limit ribs and several I shape middle ribs.Earlier C shape limit rib 1 is embedded on the grate groove, inlays I shape middle rib 2, I shape middle rib 3, I shape middle rib 4 and C shape limit rib 5 then successively, the general 30mm to 60mm of grate rib thickness, grate rib length is between the 300mm to 600mm, can adjust according to the width in gutter.Grate hole 6 width that form between grate rib and the grate rib are 30mm to 40mm.Determine the quantity of I shape middle rib according to the length needs of rain grid made, length can be adjusted arbitrarily as requested.
Claims (2)
1. a concrete of poly-acrylonitrile fiber rain grid made is made by plain polypropylene nitrile fibrous concrete, and its principal character is combined by two limit ribs and some middle ribs for each grate body.
2. according to the described a kind of concrete of poly-acrylonitrile fiber rain grid made of claim 1, its principal character is that the limit rib of grate body is a C shape, and middle rib is an I shape.
