Abstract
The utility model discloses a ductile cast iron composite telecommunication hand-hole plate, which comprises a hand-hole plate body. The hand-hole plate body comprises a ductile cast iron frame which is provided with at least one drain hole and coated with a first unsaturated polyester resin covering layer. The ductile cast iron composite telecommunication hand-hole plate has the advantages of fine burglar prevention and high shock strength.
Description
Technical field
The utility model relates to a kind of THH plate, is meant that specifically a kind of ductile iron and unsaturated-resin carry out compound spheroidal graphite combined type THH plate.
Background technology
The THH plate is one of important ancillary facility of municipal government's engineering construction.In view of present China is in rapid economic development period, the rapid growth period of city-building and vehicle bicycle capacity, the research and development of THH panel products and production work have caused that society payes attention to widely.Stolen phenomenon often appears in the cast iron type THH plate on the present urban road, becomes the hidden danger of people's trip, and shortcomings such as cast iron THH plate outward appearance is coarse simultaneously, installation is heavy, part THH plate carrying deficiency are destroyed city image.The THH plate that uses is gone up by society at present following several prods: " the steel concrete THH plate " of moulding by casting; " the glass fiber reinforced plastic THH plate " of die cast; Hot-forming products such as " regenerating resin combined manhole covers ", have all also that heaviness, fragility are big, poor toughness, easily split, characteristics such as production efficiency is low, all be not suitable for the needs of road development.
The utility model content
The purpose of this utility model is in order to overcome the shortcoming and defect that prior art exists, and the spheroidal graphite combined type THH that a kind of theftproof performance is good, shock strength is high plate is provided.
For achieving the above object, the technical solution of the utility model is, includes the handhole plate body, and described handhole plate body includes the ductile iron framework, this ductile iron framework is provided with at least one drain hole, and ductile iron framework outer wrapping is provided with the first unsaturated-resin covering layer.
Further being provided with is also to include and the handhole plate body base of scarf mutually, and this base includes the bedframe of ductile iron integral cast moulding, and the outer second unsaturated-resin covering layer that is fixed on the bedframe that coats.
The external surface that further setting is described handhole plate body is provided with the anti-skidding lines of projection.
Further being provided with is the described handhole plate body integral body shape that is rectangle.
Advantage of the present utility model is:
1, theftproof: this product adopts ductile iron as skeleton, covers resin composite materials outward, forms through hot press moulding, has not had regeneration and has been worth good anti-theft effect.
2, corrosion-resistant, ageing resistance: this product covers resin composite materials outward, and acid-alkali-corrosive-resisting is anti-aging, and service life is long.
3, safety: this product uses the high strength skeleton, does not also pulverize even reach disruptive load, can play fall arrest.
4, convenient attractive in appearance: light many of the weight ratio cast iron THH plate of this product, give and install and inspection brings great convenience.It is can classification grouped by sector painted, both has been convenient to Classification Management, and city taste is improved in the beautifying city again.
5, resistance to compression shock strength height: ductile iron framework by ductile iron integral cast moulding and bedframe provide the resistance to compression and the shock resistance of enough intensity for the THH plate, make this THH plate satisfy speedway or major urban arterial highway requirement of strength to the THH plate, applied widely.
Below in conjunction with specification drawings and specific embodiments the utility model is done further introduction.
Description of drawings
Fig. 1 the utility model specific embodiment structural representation;
Fig. 2 the utility model specific embodiment exploded view;
Fig. 3 the utility model specific embodiment A-A sectional view.
The specific embodiment
The specific embodiment of the present utility model as Figure 1-3, include handhole plate body 1, described handhole plate body 1 includes ductile iron framework 11, this ductile iron framework 11 is provided with at least one drain hole 12, and ductile iron framework 11 outer wrapping are provided with the first unsaturated-resin covering layer 13.The described drain hole 12 of present embodiment includes two, and the two is oblique relatively setting, and this drain hole 12 not only can play a role in the drainage, and can also play the effect of the stress point of handhole plate body 1 unlatching.
Present embodiment also includes and handhole plate body 1 base 2 of scarf mutually in addition, this base 2 includes the bedframe 21 of ductile iron integral cast moulding, and the outer second unsaturated-resin covering layer 22 that is fixed on the bedframe that coats, painted for the ease of the classification grouped by sector of THH plate, both be convenient to Classification Management, beautifying city again, improve city taste, the first unsaturated-resin covering layer 13 on described handhole plate body 1 and the base 2, the color of the second unsaturated-resin covering layer 22 and the solid colour on road surface, this setting, also can play certain vision interference effect, improve its theftproof performance.
In addition, the external surface of described handhole plate body 1 is provided with the anti-skidding lines 14 of projection, this anti-skidding lines 14 can direct forming on the first unsaturated-resin covering layer 13 of handhole plate body 1, the described handhole plate body 1 integral body shape that is rectangle.
