The utility model discloses reinforced concrete hollow tube column and reinforced concrete erect the common power that passes of rib downwards, have enlarged anti die -cut scope, can reduce the thickness of reinforced concrete soleplate, improve structure atress mode, and about 20% concrete can be practiced thrift in more traditional reinforced concrete stairstepping isolated footing, the solid basis of bold formula by original turns into thin -walled member, and the construction of being convenient for has reduced to reducing the working measure that bulky hydration heat for concrete taked, and then has reduced the operating expenses.
Description
Technical field
This utility model relates to the air cooling platform basis in power plant, especially relates to a kind of board-like concrete air cooling platform with perpendicular rib basis.
Background technology
Lacking area at rich coal, some build up or in newly-built thermal power plant, main frame adopts Direct Air-Cooled.Direct Air-Cooled platform loading is big, and highly high, 600MW level unit height is about 45m.Air cooling platform is frequently with the structural shape taking Steel Space Truss on large cast-in-situ steel reinforced concrete hollow pipe column, and the distance between tubing string is at about 20m.Due to highly high, loading is big, and under the effect of wind or earthquake, the internal force reaching basis is very big, and the design on basis is proposed significantly high requirement.
It is big that air cooling platform hollow pipe column post root internal force is characterized as being axle power, and moment of flexure is also big.Due to tubing string spacing farther out, basis is frequently with armored concrete staged isolated footing.Power owing to acting on basis is big, and the area of isolated footing is very big.When foundation bearing capacity is 400kPa, air cooling platform foundation ' s bottom area reaches about 13m × 13m.Foundation ' s bottom area is big, and the height of basic each step is also high.For adjusting the jib-length of base plate, the width of each step need to be adjusted to meet requirement.The volume of concrete of so single isolated footing just reaches about 300m3.Generally, a 600MW level air cooling platform has 16 bases, and the base concrete amount of an air cooling platform is 4800m3, the amount of concrete of ten thousand stere is nearly gone up on two 600MW level air cooling platform bases.Visible air cooling platform base concrete quantities is huge, consumes substantial amounts of cement, sand, stone and construction water, damage to land, adds heavily contaminated.The concrete of additionally so big volume is not easy to construction, increases working measure expense to reduce the heat of hydration.Create substantial amounts of building waste simultaneously, be not easy to after shutdown of power plant remove, place recycling difficulty.
Utility model content
The purpose of this utility model is to provide a kind of board-like concrete air cooling platform with perpendicular rib basis, to reach to reduce concrete works amount, convenient construction, improves the purpose of comprehensive benefit.
For achieving the above object, this utility model provides a kind of basis of the board-like concrete air cooling platform with perpendicular rib, including steel bar concrete foundation slab, reinforced concrete hollow tubing string, it is characterized in that: in steel bar concrete foundation slab, be reserved with perpendicular rib reinforcement, water post around perpendicular rib reinforcement and have perpendicular rib concrete, form the perpendicular rib of armored concrete.
The perpendicular rib of described armored concrete is distributed in steel bar concrete foundation slab diagonal place.
The height of the perpendicular rib of described armored concrete is gradually increased to reinforced concrete hollow tubing string by steel bar concrete foundation slab edge.
This utility model adopts the board-like concrete air cooling platform basis of the perpendicular rib of band, compared with traditional armored concrete stairstepping isolated footing, has the advantage that
Reinforced concrete hollow tubing string and armored concrete perpendicular rib power transmission downwards jointly, expand the scope of Punching Shear, it is possible to reduce the thickness of steel bar concrete foundation slab.Stepped footing base plate is cantilever slab, adopts the flat basis of the perpendicular rib of band to make base plate become three simply supported slabs, improves structure stress pattern, make base plate thickness reduce further.In the suitable situation of bearing capacity, the concrete of about 20% can be saved in more traditional armored concrete stairstepping isolated footing, board-like concrete air cooling platform basis of the perpendicular rib of each employing band.For whole air cooling platform bases, a considerable number of.
Adopt the mat foundation of the perpendicular rib of band, make the original solid basis of bulk formula be converted into thin-wall member, it is simple to construction.Decrease the working measure taked for reducing the mass concrete heat of hydration, and then reduce operating expenses.
Visible; this utility model is except realizing the purpose of reduction concrete works amount; also bring following social benefit: save the construction materials such as cement, stone, sand, construction water; meet the industrial policy of state guarantee soil and water resource, energy-saving and emission-reduction, protection environment, reach green industry building standard；Decrease the working measure of the heat of hydration, reduce operating expenses；Decrease building waste to produce, after power plant disables, it is easy to remove building waste, it is simple to re-use place.Along with the development of society, land resource will be abnormal rare, and the discarded recycling taken up an area will be more exposed to pay attention to.In sum, the board-like concrete air cooling platform basis of the perpendicular rib of this band has extraordinary comprehensive benefit.

Detailed description of the invention
With reference to Fig. 1, this utility model mainly includes steel bar concrete foundation slab 1, reinforced concrete hollow tubing string 3, is provided with the perpendicular rib 2 of the armored concrete being made up of the perpendicular rib reinforcement reserved and perpendicular rib reinforcement concrete in steel bar concrete foundation slab 1.The perpendicular rib 2 of armored concrete is distributed in steel bar concrete foundation slab 1 diagonal place.
With reference to Fig. 2,4 is design blinding layer below steel bar concrete foundation slab.Steel bar concrete foundation slab is poured into a mould by steel bar concrete foundation slab reinforcing bar 101 and steel bar concrete foundation slab concrete 102 and is constituted.Reinforced concrete hollow tubing string is poured into a mould by reinforced concrete hollow tubing string reinforcing bar 301 and reinforced concrete hollow tubing string concrete 302 and is constituted.In order to save quantity of material further, mating with stress, the height of the perpendicular rib 2 of armored concrete is gradually increased to reinforced concrete hollow tubing string by steel bar concrete foundation slab edge.
With reference to Fig. 3, the perpendicular rib of armored concrete is made up of perpendicular rib concrete 202 cast of the perpendicular rib reinforcement 201 of armored concrete and armored concrete, and 3 is reinforced concrete hollow tubing string, and 4 is blinding layer.
With reference to Fig. 4, steel bar concrete foundation slab 1, blinding layer 4, armored concrete erect rib reinforcement 201, the perpendicular rib concrete 202 of armored concrete.
During construction, on ground, first build blinding layer 4, reach after requirement until intensity, formwork, the perpendicular rib reinforcement 201 of assembling reinforcement concrete floor reinforcing bar 101, pouring reinforcement concrete underplate concrete 102, and reserved steel bar concrete and reinforced concrete hollow tubing string reinforcing bar 301.Following formwork, and continue the perpendicular rib reinforcement 201 of assembling reinforcement concrete and reinforced concrete hollow tubing string reinforcing bar 301, the then perpendicular rib concrete 202 of pouring reinforcement concrete and reinforced concrete hollow tubing string concrete 302.After base concrete intensity reaches requirement and do necessity process after, formwork, continue construction upper reinforcement concrete hollow tubing string.
