Abstract
The utility model discloses a manhole cover, frame made of glass fibre reinforced plastic fibre composite. A steel support bracket used as a reinforcing rib is inserted inside the round manhole cover made of glass fibre reinforced plastic fibre composite. The steel support bracket is fixedly bond with the glass fibre reinforced plastic fibre composite. Steel reinforcing ribs are inserted into the frame; the manhole cover and the frame are separate bodies. An antitheft pin and an antitheft lock are provided respectively on the two ends of the diameter of the manhole cover. An antitheft pin hole and an antitheft lock hole are arranged symmetrically on the frame. The utility model has the advantages of light weight, temperature proof, pressure resistance, corrosion proof, ageing resistance, high strength, good toughness and no brittle cracking etc.
Description
Technical field
The utility model relates to a kind of cover for water supply and drainage manholes, well seat.Particularly a kind of reinforced plastic glass fibre composite material cover for water supply and drainage manholes, well seat.
Background technology
Existing well lid and well seat majority are made by cast iron, about 50 kilograms of single lid weight, and weight is big, maintenance inconvenience, impact resistance is poor, crushed by vehicle often, and easily stolen, cause damage for pedestrian and vehicle.The appearance of part novel metalloid composite drain cover has improved the impact resistance of well lid, but the compressive strength of well lid is not high, easily embrittlement, and heatproof and corrosion resistance are poor.
Summary of the invention
The purpose of this utility model is to overcome existing deficiency in the above existing well lid, and a kind of heatproof, withstand voltage, corrosion-resistant, anti-aging is provided, intensity height, good toughness, not embrittlement and antitheft new glass fibre reinforced plastic fibrous composite cover for water supply and drainage manholes, well seat.
To achieve these goals, the utility model reinforced plastic glass fibre composite material cover for water supply and drainage manholes, the well seat, comprise round manhole cover 1, well seat 2 and reinforcing rib, it is characterized in that by unsaturated polyester resin, the synthetic reinforced plastic glass fibre composite material round manhole cover 1 of additive and aging-proof agent is embedded with steel body bracing frame 3 as reinforcing rib, described steel body bracing frame 3 is consolidated with the reinforced plastic glass fibre composite material, well seat 2 is embedded with steel body reinforcing rib 4, described steel body reinforcing rib 4 is consolidated with the reinforced plastic glass fibre composite material, well lid 1 and 2 splits of well seat, be respectively equipped with one at the two ends of well lid 1 diameter and prevent stealing and selling 5 and one theftproof lock 7, on well seat 2, be arranged with antitheft pin-and-hole 6 and antitheft lockhole 8.
Described steel body bracing frame is groined type or grid-shaped in circle.
Described steel body bracing frame is an A3 band steel.
This novel characteristics are: the environmental protection of reinforced plastic glass fibre composite material, heatproof, withstand voltage, corrosion-resistant, anti-aging, intensity height, good toughness, not embrittlement, anti-steal and sell with the setting of theftproof lock can be effectively antitheft.It is applicable to engineerings such as plumbing, municipal administration, road.
Description of drawings
Below in conjunction with accompanying drawing the utility model reinforced plastic glass fibre composite material cover for water supply and drainage manholes, well seat are described in further details.
Fig. 1 is the utility model reinforced plastic glass fibre composite material cover for water supply and drainage manholes, well seat longitudinal section.
Fig. 2 is the utility model well lid upward view.
Fig. 3 is the utility model well seat sectional elevation.
Specific embodiment
As shown in Figure 1, 2, 3, the utility model reinforced plastic glass fibre composite material cover for water supply and drainage manholes, well seat are made up of round manhole cover 1, well seat 2 and reinforcing rib.The reinforced plastic glass fibre composite material round manhole cover 1 synthetic by unsaturated polyester resin, additive and aging-proof agent is embedded with steel body bracing frame 3 as reinforcing rib, steel body bracing frame 3 is consolidated with the reinforced plastic glass fibre composite material, well seat 2 is embedded with steel body reinforcing rib 4, and steel body reinforcing rib 4 is consolidated with the reinforced plastic glass fibre composite material.Well lid 1 and the 2 split settings of well seat are respectively equipped with at the two ends of well lid 1 diameter and anti-ly steal and sell 5 and theftproof lock 7, are arranged with antitheft pin-and-hole 6 and antitheft lockhole 8 on well seat 2.
When assembling is used, the anti-5 antitheft pin-and-holes of aiming on the well seat 26 of stealing and selling on the well lid 1 are inserted, well lid 1 falls in the well seat 2 immediately, theftproof lock 7 is inserted corresponding antitheft lockhole 8 can prevent the stolen of the utility model reinforced plastic glass fibre composite material cover for water supply and drainage manholes, well seat.
