Abstract
The utility model discloses a ductile iron and steel fiber well grating, which comprises an integrated ductile iron well grating framework and steel fiber concrete; the integrated ductile iron well grating framework consists of a frame, horizontal ribs and vertical ribs, wherein the horizontal ribs are horizontally arranged in the frame, and the vertical ribs are vertically arranged in the frame; the center of the bottom of the structure formed by the horizontal ribs and the vertical ribs is higher than the edges of the frame, the horizontal ribs and the vertical ribs extend downwards from the edges of the frame, are arranged in the frame in a bulged and mutually crossed manner, and are integrated with the frame; and a bearing plate is arranged on the inner side of the bottom of the frame. The ductile iron and steel fiber well grating has the characteristics of high overall strength, great bearing capacity, strong stability, good fatigue resistance performance, reliability in use, long service life, low price and the like; the appearance of the ductile iron and steel fiber well grating is similar to that of a cement product which has no recovery value, so that the ductile iron and steel fiber well grating is prevented from being stolen; and the ductile iron and steel fiber well grating is an ideal upgrading product for eliminating city traps and replacing well gratings made of other materials.
Description
Technical field
The utility model relates to a kind of well grate, definite a kind of well grate by ductile iron integral type well grate skeleton and steel fibrous concrete combined preparation of saying so.
Background technology
At present, the cast iron well grate that uses on avenue, the highway, it is very general to lose phenomenon, and the well grate insufficient strength of other material is damaged very seriously, brings great potential safety hazard for trip vehicle and pedestrian, and the situation that tumble injury disables happens occasionally.
Summary of the invention
Therefore, there is great demand in people to well grate antitheft, that bearing pressure is big, up to now, also do not find about relevant report of the present invention, the inventor is through a large amount of development tests, the Antitheft manhole cover of developing usefulness ductile iron integral type well grate skeleton and steel fibrous concrete preparation of success finally, thus the present invention finished.
The purpose of this utility model just provides a kind of big Antitheft manhole cover of supporting capacity with ductile iron integral type well grate skeleton and steel fibrous concrete preparation.
Scheme of the present utility model comprises ductile iron integral type well grate skeleton and steel fibrous concrete, described ductile iron integral type well grate skeleton is by frame, horizontal bar and perpendicular muscle are formed, the inboard of frame is provided with transversely arranged horizontal bar and vertically disposed perpendicular muscle successively, the height at horizontal bar and perpendicular muscle bottom center place is higher than the height at frame edge place, edge by frame extends projection downwards, it is arranged in a crossed manner in frame mutually to be convex, be cast as one with frame, the inboard, the end of frame is provided with the load-bearing supporting plate, the two ends up and down of ductile iron integral type well grate skeleton are filled with steel fibrous concrete, and steel fibrous concrete and the combination of ductile iron integral type well grate skeleton are solidified as one.Described steel fibre (market is on sale) is a kind of steel, filament type material, and it can increase the cohesive force of steel fibre and cement mortar, strengthens concrete bulk strength, and its anti-folding, resistance to compression, cracking resistance, scuff resistance are obviously improved.Ductile iron integral type well grate skeleton is the novel product of technical research of adopting new technology, after the molten iron of fusing soaks heat treatment through nodularization material close to steel, and inexpensive, have aesthetic in appearance, durable in use, the intensity height, in light weight, use economic characteristics.Ductile iron integral type well grate skeleton is set in steel fibrous concrete well grate, with steel fibrous concrete ductile iron integral type well grate skeleton is wrapped up, ductile iron integral type well grate skeleton is enclosed in the layer of concrete, makes ductile iron integral type well grate skeleton and air isolated, never corrosion.It is very strong that the back bonding force is solidified in steel fibrous concrete and the combination of ductile iron integral type well grate skeleton, long service life, ductile iron integral type well grate skeleton is wrapped up by steel fibrous concrete, concrete edge in the well grate is along being wrapped up by ductile iron integral type well grate skeleton frame, effectively guaranteed the bulk strength of well grate, supporting capacity is big, and stability, anti-fatigue performance is good.The utility model can make circular, square or rectangular shape with the well grate as required.
Characteristics such as the utlity model has the bulk strength height, supporting capacity is big, and stability is strong, and anti-fatigue performance is good, uses reliably, and the life-span is long, and is cheap, its outward appearance is similar to cement products, reclaims no recycle value.Therefore, need not worry robbed or burgledly, be the desirable regeneration product of eliminating the city trap and upgrading other material well grate.
Be described in further detail below in conjunction with accompanying drawing.
