Abstract
The utility model relates to a super heavy steel fiber concrete gully grating, which is composed of a frame, a grid, reinforcing ribs and reinforcing hoops. The utility model is characterized in that the super heavy gully grating made of steel fiber concrete is rectangular or square, and the lower part of the grid is provided with the reinforcing ribs. A three-dimensional reinforcing space steel bar framework is assembled in the grating, and the circumferential edge of the grating is provided with the reinforcing hoops. Compared with the existing heavy cast iron rain grating which satisfies steam-15 load use requirements, the gully grating decreases the weight 20% or so, and reduces the price more than 45%. The utility model can satisfy steam-25 load use requirements. The shock resistance is good, and the utility model which is not easy to corrode does not lose. The utility model improves the bearing capacity near 80 times than the carrying capacity of a fiber mortar or fiber concrete light gully grating, and the utility model can be widely used at water outlets in various roads, fields or areas.
Description
The utility model belongs to a kind of outfall sluicing grate of municipal engineering.
The sluicing grate of municipal engineering outfall generally is cylinder iron to make.Form by frame, grid and ribs.Be rectangle or square.Ribs is an in-line, arranges in short.There is following shortcoming in it: the first will be used a large amount of cast irons, the structure heaviness, and also every all need be made sand mold cast, complex process, and the cost height, production environment is abominable; The 2nd, cast iron is fragile material, and shock resistance is poor; It three is easy corrosions; It four is stolen easily.Other has a kind of fibre mortar and the light-duty grate gutter inlet of fibrous concrete (patent No. 89.2.14424.6), and it can only bear less load and (press 400kg/m
2No meter), at heavy vehicle (15 tons heavy automobiles, be called for short vapour--15) and superduty vehicle (20 tons heavy automobiles, be called for short vapour--20, below analogize) start the location, damage easily because the hardness of the intensity of its main rib, frame and supporting periphery is not enough, particularly when laying out-of-flatness, the easier generation knuckle of frame, mashed limit and can not use.
The purpose of this utility model provides a kind of superduty steel fibrous concrete grate gutter inlet, is provided with at the frame periphery and strengthens hoop; The three-dimensional space cage of reinforcement that strengthens is set in frame, grid and the ribs.Make this grate gutter inlet overcome the shortcoming of cast iron grate gutter inlet and fibre mortar and the light-duty grate gutter inlet of fibrous concrete, improved bearing capacity greatly.Be applicable to and make the superduty grate gutter inlet.
Superduty steel fibrous concrete grate gutter inlet of the present utility model, form by frame, grid, ribs and reinforcement hoop, it is characterized in that: the superduty grate gutter inlet of being made by steel fibrous concrete is a rectangle or square, the 4--8 bar is set in the bottom, orthogonal thereto layout, longitudinal section is parabolic ribs.Configuration parabolic shape reinforcing bar in the ribs.Reinforcing bar in frame, the grid and the reinforcing bar in the ribs strengthen the space cage of reinforcement with the three-dimensional that stirrup unifies.The periphery of grate is provided with strengthens hoop.
Described reinforcement hoop is made the squarely hoop with band steel, burn-ons or do not weld with the grate periphery and water the dowel that builds up integral body in hoop inside.
Described reinforcement hoop is made the squarely hoop with angle steel, burn-ons or do not weld with the grate periphery and water the dowel that builds up integral body in hoop inside.
Described steel fibre can be the steel fibre of producing with shearing method; Steel fibre that the molten method of taking out is produced or the steel fibre of producing with the cut-out of thin steel (iron) silk etc.
Superduty steel fibrous concrete grate gutter inlet of the present utility model, because the three-dimensional space cage of reinforcement that strengthens of preparation in the grate, the grate periphery is provided with strengthens hoop, can satisfy vapour--the instructions for use of 25 loads.Every heavily about 40 kilograms, about 100 yuan of price.Than original vapour--every of the heavy cast iron grate that 15 loads use is heavy 47.7 kilograms, and weight reduces about 20%.About 180 yuan of every price, price reduces more than 45%.Shock resistance is good, and is not perishable, do not lose, and improves nearly 80 times of supporting capacity than fibre mortar or the light-duty grate gutter inlet of fibrous concrete, can be widely used in the outfall in different kinds of roads, place or area.
Below in conjunction with drawings and Examples superduty steel fibrous concrete grate gutter inlet is done progressive the description.
Fig. 1 is a vertical view of the present utility model.
Fig. 2 is a longitudinal plan of the present utility model.
Fig. 3 is a drawing in side sectional elevation of the present utility model.
As shown in the figure, 2. the frame of grate has grid in 1., and discharge opening 4..There are seven 3. orthogonal thereto layouts of ribs at its back side.The longitudinal section of rib is a parabolic shape.Reinforcing bar in grate frame and the grid and the reinforcing bar in the ribs strengthen the space cage of reinforcement with the three-dimensional that 5. stirrup unifies.Strengthen hoop and 6. encase frame.
The size of grate is general wide to be 300mm--600mm, and long is 300mm--800mm; The thickness of grate can be 30mm--50mm; The ribs height can be 70mm--150mm, and wide is 25mm--70mm.
The making of grate can be according to the match ratio of the material selection steel fibrous concrete that uses, and for example can adopt the 525# ordinary Portland cement: sand: stone=concrete of 1: 2: 1.5 adds the steel fibre of volume of concrete 2% again, mixes and stirs cast by the 0.40--0.50 water/binder ratio.
Superduty steel fibrous concrete grate gutter inlet of the present utility model, supporting capacity stipulates that than the heavy grate of the national universal standard figure S235 instructions for use of vapour-15 load improves two grades.Satisfy vapour--the instructions for use of 25 loads.Result of the test is as shown in the table:
Load 10 20 30 40 50 60 70 80 90 100 110 120 130 140
(kn) accumulative total is out of shape bearing and is out of shape 13 17 24 32 40 48 58 69 80 95 110 125
(0.01)
When applying uniform total load 120KN simultaneously on three short ribs, maximum distortion is 0.95mm, and crack width is less than 0.2mm.Rupture load surpasses 140KN.The design load of vapour-15 requires to be 50KN that actual bearer ability of the present utility model is a vapour--2.4 times of 15 load requirements, improve nearly 80 times of supporting capacity than 89.2.14424.6 utility model patent grate.
Conclusion is got up, superduty steel fibrous concrete grate, than only satisfying vapour--it is about 20% that every of the heavy cast iron grate of 15 load instructions for uses reduces weight, reduces price about 45%.Can be about substantial contribution of country and cast iron materials as being extensive use of, can avoid losing traffic and the human casualty accident that brings simultaneously because of grate.
