Abstract
A manhole cover of GFRP is composed of upper and lower halves stuck together, and features that said upper and lower halves are made up by alternatively sticking one of layers of resin with one of layers of glass fibre cloth, one by one. Its advantages are beautiful moulding, high compression strength, light weight and no deformation.
Description
The present invention relates to a kind of and the glass fibre reinforced plastic manhole covers network of underground ancillary engineering facility.
At present the well lid that uses is generally casting iron well lid, this casting iron well lid heaviness, and operation labor intensity is big, and is not attractive in appearance, easily gets rusty, and loses phenomenon and happen occasionally.
The objective of the invention is to overcome weak point in the prior art, and a kind of glass fibre reinforced plastic manhole covers is provided.
This glass fibre reinforced plastic manhole covers, it is by the well lid first half and the latter half is bonding forms, the latter half that it is characterized in that well lid is one deck resin layer of glass cloth bonding forming that alternately superpose from bottom to top, well lid the first half from top to bottom one deck resin layer of glass cloth alternately stack is sticking by forming.Resin is stuck with paste as curing compound for the benzoyl peroxide dibutyl phthalate that adds 2～4 part 50% in 100 parts of unsaturated polyester resins successively, 0.5～3 part 10% N.N-dimethylaniline styrene solution is as accelerator, stir, can construct, normal temperature cure, the construction environment temperature can not be lower than 15 ℃, and the air relative temperature should be less than 80%.Glass fabric can be specifications such as 900 * 1000 * 4mm or 900 * 1000 * 2mm.
This glass fibre reinforced plastic manhole covers compare with casting iron well lid have in light weight, handsome in appearance, easy to use, resistance to compression is durable, parallelism is high, indeformable, be convenient to packing and advantages such as transportation, real be the optimal supporting well head coverings of network of underground engineerings such as municipal administration, public security, telecommunication, water supply, fire-fighting, blowdown.
Fig. 1 a is the glass fibre reinforced plastic manhole covers front view
Fig. 1 b is the glass fibre reinforced plastic manhole covers upward view
Fig. 1 c is the glass fibre reinforced plastic manhole covers vertical view
Fig. 2 is the glass fibre reinforced plastic manhole covers sectional view
Fig. 3 is a glass fibre reinforced plastic manhole covers middle body marking pattern
Now the present invention is further illustrated in conjunction with the accompanying drawings.
With reference to Fig. 2, first coating release agent in counterdie 1 is as zapon, be coated with one deck resin 2 again, coating 10mm is thick, puts layer of glass cloth 3 then, one deck resin layer of glass cloth alternately superposes to be bonded to and reaches till the desired thickness, constitutes glass fibre reinforced plastic manhole covers the latter half 4.Making glass fibre reinforced plastic manhole covers the first half 6 in patrix 5, also is one deck resin 7 and layer of glass cloth 8 bonding the forming that alternately superpose.Patrix 5 is turned on the counterdie 1 pressurization 1～2kg/cm
2The first half 6 of glass fibre reinforced plastic manhole covers is bonded together with the latter half 4, normal temperature solidified 30 minutes down, the demoulding then, send into temperature and be in 40～60 ℃ the drying room and carried out drying 1 hour, then carry out surfacing, on glass fibre reinforced plastic manhole covers, make lifting hole, the qualified warehouse-in of the examination and test of products again with Mechanical Method.The tensile strength of this product is greater than 1200kg/cm
2, cold resistance be-20 ± 3 ℃ indeformable, heat resistance be 40 ± 3 ℃ indeformable.
Claims (3)
1. glass fibre reinforced plastic manhole covers, it by and cover half part and the latter half is bonding forms, the latter half that it is characterized in that well lid is one deck resin layer of glass cloth bonding forming that alternately superpose from bottom to top, and well lid the first half is one deck resin layer of glass cloth bonding forming that alternately superpose from top to bottom.
2. glass fibre reinforced plastic manhole covers according to claim 1, it is characterized in that resin is to add 2～4 part 50% benzoyl peroxide dibutyl phthalate successively to stick with paste as curing compound in 100 parts of unsaturated polyester resins, 0.5～3 part 10% N.N-dimethylaniline styrene solution is as accelerator.
3. glass fibre reinforced plastic manhole covers according to claim 1 and 2 is characterized in that glass fabric can be specifications such as 900 * 1000 * 4 or 900 * 1000 * 2.
