Abstract
The utility model relates to a well grate lid and a well lid with high-strength dabber structure, characterized in that the cover board floor edging of the well grate lid and the well lid is provided with an abeyance surface engaged with a cover seat, an annular reinforced bead bumping the cover board floor is provided on the cover board floor inside the cover seat. The well grate lid and the well lid with high-strength dabber structure has the advantage of simple structure, convenient manufacture, high bearing strength and long durability, the annular reinforced bead of high-strength dabber structure disperses local pressure effectively, reinforces force balance of the cover board. The resistance intensity to pressure and crack of the well grate lid and the well lid is increased in magnitude order, the durability is as five times as current ones with the same thickness. The well grate lid and the well lid with high-strength dabber structure applies to special type road, city road, highway, parking area for automobiles and cars at airport to ride and park and inspection pit, raining scavenge port of municipality, community and arboretum.
Description
Technical field
The utility model belongs to motor vehicles such as urban road, highway, factory, living community and travels or park non power driven vehicles such as place and gardens, greening and travel and park the well lid of manhole in place and the well grating field of draining inlet for stom water, relates in particular to a kind of well grating and well lid with high strength reinforcing rib structure.
Background technology
Be used for the travel manhole well lid in standage and the well grate of draining inlet for stom water of extraordinary road, airport or motor vehicles and must have good resistance to compression supporting capacity.Though the well grate of the manhole well lid of cast iron quality and drainage inlet for stom water can satisfy the requirement of high bearing capacity, because the cost cost is high and recycling property, stolen phenomenon is very serious, has had a strong impact on vehicle and pedestrian's safety.The manhole well lid of steel fibrous concrete material and drain mouth of a river well grating and obtained throughout the country using widely, but plate shaped well grating and its supporting capacity of well lid are relatively poor is easy to occur crack and breakage through after the rolling of load-carrying vehicle.The at present bar shaped of setting up protrusion in the bottom surface of well grating and well lid or crossed reinforced muscle of adopting to strengthen the bearing strength of its overhanging portion more, though this has increased the intensity of well grating and well lid to a certain extent, but still can not solve well grating and the easy problem of damaging of well lid.Its main cause is that steel fibrous concrete well grating and well lid are under bigger bearing pressure, the middle part cover plate is subjected to the pressure of vertical direction excessive, hanging part and the stressed difference maximum of shelving the jointing edge of face, therefore the place that occurs the crack easily is near the cover plate the face of the shelving inner side edge that combines with cage, and the cover plate at well grating and well lid middle part.Existing settling mode is that the periphery at well lid coats a quoit, and the edge of well lid is reinforced.
Though can increase its supporting capacity to a certain extent by the method that increases well grating and well lid integral thickness, but the height that must increase the well seat is simultaneously installed to cooperate, this makes well lid and cage become heavy, has also increased manufacturing cost, and installation difficulty also increases thereupon.
The utility model content
The purpose of this utility model provide a kind of simple in structure, have that high strength reinforcing rib structure, supporting capacity are strong, the well grating and the well lid of long service life, it is poor to have solved the ubiquitous supporting capacity of existing well grating and well lid, the defective that application life is short.
The technical solution adopted in the utility model is as follows:
A kind of well grating and well lid with high strength reinforcing rib structure, the cover plate bottom surface that it is characterized in that described well grating and well lid is provided with the annular reinforcement fin that protrudes the cover plate bottom surface, and the cover plate bottom surface that annular is strengthened the fin outside is provided with the face of shelving that combines with cage.
Described well grating and well lid are rectangle, and annular is strengthened fin also for protruding the rectangle frame of cover plate bottom surface
The cover plate of described well lid is circular, and the annular of cover plate bottom surface is strengthened fin also for protruding the cylindrical shape of cover plate bottom surface.
Described well grating and well lid are rectangle, and well grating and well lid cover plate bottom surface are provided with the annular of vertical protrusion and strengthen fin, and the cover plate bottom surface of fin outside is provided with the face of shelving that combines with cage.
The described face of shelving is arranged on well grating and relative both sides of the edge, well lid cover plate bottom surface.
The face of shelving of the cover plate bottom edge of described well grating and well lid is the inclined plane that certain angle is arranged with horizontal plane.
The cover plate bottom surface that described annular is strengthened the fin inboard is provided with bar shaped or the crossed reinforced muscle that protrudes the cover plate bottom surface.
The height that described annular is strengthened fin is well grating and well lid cover sheet thickness 1～5 times.
Encircle and state annular and strengthen fin and well grating or the coaxial setting of well lid, the reinforcement fin is contour closed ring projection.
Annular is strengthened fin near shelving face, and is positioned at the outer rim of described cover plate bottom surface.
Annular is strengthened the local pressure dispersion that fin can be effectively be subjected to well grating and well lid overhanging portion, eliminates unbalanced stressed destruction to well grating and well lid cover plate.Be positioned on the cover plate bottom surface of shelving the face inboard because annular is strengthened fin, near shelving face, thereby increased stressed maximum and the intensity of the relatively poor face of the shelving inside edge of supporting capacity.The slit of the annular reinforcement fin that protrudes downwards and the lateral wall piece of manhole or inlet for stom water is very little, when vehicles or pedestrians at a high speed through out-of-date, annular is strengthened fin and can not beat and displacement by the restriction of the borehole wall, and this has also guaranteed the supporting capacity of well grating and well lid and stressed equilibrium effectively.
Annular is strengthened fin can be for protruding the rectangle frame or the cylinder of cover plate bottom surface, and this generally determines according to the shape of its well head of placing.Having annular, to strengthen the processing and manufacturing of the well grating of fin and well lid fairly simple, and annular is strengthened fin and well grating, well lid are monoblock cast, can be by a die sinking of mold preparation.
The beneficial effects of the utility model are, this have the well grating of high strength reinforcing rib structure and well lid have simple in structure, easily manufactured, bearing strength is high and the advantage of long service life, the reinforcing rib structure that its annular is strengthened fin can effectively disperse local pressure, strengthens the stress balance of cover plate.Annular ridge is arranged on the edge of well grating or well lid plate, the breakage that prevented from the limit, the angle begins, and the existing simultaneously ferrule that is coated on well grating or well lid plate periphery can be removed, and has saved metal material.The resistance to compression of this well grating and well lid and rupture strength obtain the increase of order of magnitude multiple, and be the well grating and more than 5 times of well lid of existing stack pile cover plate its application life.This have the well grating of high strength reinforcing rib and well lid can be widely used in extraordinary road and airport, motor vehicles travel places such as place such as the urban road parked, highway, parking lot and municipal administration, community, greening gardens manhole and drain inlet for stom water.
