Abstract
The utility model discloses a moulded compound material manhole cover, which comprises the manhole cover and a cover seat, wherein the manhole cover is composed of a cover edge and a cover body. A cover face is provided with skidproof veins and an opening bore. The cover seat is composed of an inner ring, a manhole edge, a reinforcing ring and an outer ring. The manhole cover and the cover seat are composed of an outer coating layer made of glass fiber reinforced plastic compound materials and a built-in steel bar structural frame. The steel bar structural frame in the manhole cover is composed of a steel bar turn of the cover edge and a steel bar arc-shaped crossed frame of the cover body which are welded and connected with each other. The bottom of the cover body presents an up throwing dome shape. The moulded compound material manhole cover not only has all the advantages of general moulded compound material manhole covers, but also can cause strength to achieve an unprecedented degree. Every parameter index all achieves a standard of the national construction ministry. The utility model can replace an iron manhole cover completely, and can be used in the construction of municipal roads.
Description
Technical field
The utility model relates to a kind of composite material moulded inspection shaft lid that city road inspection shaft is built that is used for.
Background technology
Because traditional cast iron inspection shaft is stamped higher recovery value, is easily stolen, consequently often there is unfortunate event to take place, caused this evitable heavy losses to family social, also perplexed municipal supervision department.And also having a lot of deficiencies at composite applications inspection shaft lid on the market now: the first is owing to general mold pressing bottom surface plane or fin type, and the mechanical structure design is unreasonable, and lid easily breaks when load-bearing; Its two be when the frequent high ram compression of vehicle out-of-date, well circle suitable for reading begins to break, and forms many small gaps, has both influenced sight, has also destroyed bulk strength; It three is that cage triangle boss support strength is not enough, when truck by the time, whole cage occurred and broken.These problems all can cause immeasurable consequence.
Summary of the invention
The purpose of this utility model be provide for the deficiency that solves above-mentioned technology that a kind of fastness is big, intensity highly is difficult for breaking, composite material moulded inspection shaft lid safe in utilization.
In order to achieve the above object, a kind of molded composite material inspection shaft lid that the utility model is designed, it comprises well lid and cage, well lid is made up of lid edge and lid, anti-skidding line and open hole are arranged on the capping, cage is made up of inner ring, well, stiffening ring and outer ring, and well lid and cage are configured to by glass fiber reinforced plastics composite material surrounding layer and embedded bar construction.Bar construction frame in the described well lid intersects frame by lid along reinforcing bar circle and lid reinforcing bar arc and is welded to connect and constitutes, and the lid bottom surface is upthrow dome shape.Bar construction frame in the cage divides two-layer, and the upper strata is a well reinforcing bar circle, and lower floor is inner ring reinforcing bar circle and outer ring reinforcing bar circle, and three reinforcing bar circles fall " fourth " font reinforced frame location by three.The vertical section, well of cage is at right angles trapezoidal.
The resulting composite material moulded inspection shaft lid of the utility model, except all advantages with general composite material moulded inspection shaft lid, more make its intensity reach unprecedented degree, the parameters index has all reached the nation-building ministerial standard, iron inspection shaft lid can be replaced fully, the construction of town road can be widely used in.
