Description
Technical field
The utility model belongs to steam power station coal unit technical field, particularly relates to a kind of steam power station coal storage facility---the structural shape of circular coal yard.
Background technology
Circular coal yard is the critical facility of steam power station coal storage, has that coal storage capacity is large, environmental-protecting performance is outstanding, takes up an area less and program control horizontal advantages of higher, and thus in power plant, particularly the application of coastal region power plant is more.
The structural shape of current circular coal yard can be divided into two large classes usually: separate type and monolithic, wherein monolithic is divided into again pure barrel monolithic and monolithic with ribbing two kinds.These three kinds of structural shapes main feature is separately as follows:
Separate type: annular coal-stopping wall establishes seam to disconnect at each buttress place, both sides freely-supported is on buttress, and lower end is clamped on ring foundation.Buttress is a cantilever construction, and lower end is clamped on ring foundation, upper end bearing large span space Elements of Space Grid Truss.Ring foundation is an overall structure.Separate type is clearly stressed, can be reduced to plane structure and carry out force analysis.
Pure barrel monolithic: do not establish buttress, annular coal-stopping wall is made an integral barrel wall construction, lower end is clamped on ring foundation, and high supporting large span space Elements of Space Grid Truss is stretched in local, upper end.Ring foundation is an overall structure.Stressed and the computational analysis relative complex of pure barrel monolithic construction, should spatially structure adopt finite element software to calculate.
Monolithic with ribbing: on the all-in-one-piece basis of pure barrel, sets up perpendicular rib (buttress) along barrel certain angular interval, and arranges horizontal ring beam together at barrel top.Perpendicular rib (buttress) can strengthen cylindrical wall on the one hand, increases its resistance to overturning, raises the supporting-point that also can provide rack on the other hand at barrel top.Top ring beam can provide spacious operating maintenance space, and can adapt to portal type scraper reclaimer preferably.
Monolithic with ribbing is a kind of Novel circular coal yard structure pattern just occurred in engineering in recent years, it combines the feature of separate type and pure barrel monolithic two kinds of structural shapes, adding the integral rigidity of circular coal yard barrel and strengthen the node of rack supporting, is a kind of structural shape that in current engineering, monolithic circular coal yard generally adopts.But the barrel of this structural shape bears larger hoop tension causes crack width wayward, and larger by the impact of local coal piling, asymmetric coal piling and differential settlement.
Summary of the invention
In order to solve the problems of the technologies described above, the utility model provides a kind of monolithic circular coal yard structure of band rib, reduce the impact by local coal piling, asymmetric coal piling and differential settlement, and by part hoop tension by barrel steering ring rib, the crack width of barrel is easily controlled.
Solve the monolithic circular coal yard structure of a kind of band rib in the utility model of above technical problem, comprise ring foundation, barrel, top ring beam and perpendicular rib, barrel lower end is fixed on ring foundation, ring foundation, barrel and top ring beam are overall structure, barrel lower end is connected with top ring beam, top ring beam is made to be horizontally set on ring beam barrel top, perpendicular rib is arranged along barrel interval, perpendicular rib lower end is located on ring foundation, perpendicular rib upper end is connected with top ring beam, it is characterized in that: be also provided with ring rib, ring rib is located on barrel outer wall, ring rib is parallel with ring foundation.
In the utility model, the rib of ring described in prioritization scheme is located on barrel outer wall through perpendicular rib.
Described in further prioritization scheme, structure is also provided with rack pillar, and rack pillar is located on the ring beam of top.
Position and the quantity of the position of described rack pillar on the ring beam of top and quantity and perpendicular rib are consistent.
Described ring rib quantity >=1.
Rack pillar is in order to support the large span space Elements of Space Grid Truss at circular coal yard top.
The utility model, on the basis of monolithic circular coal yard with ribbing, arranges the ring rib of some along the increase of barrel height, the quantity of ring rib should be determined after analyzing as calculated in conjunction with circular coal yard diameter, barrel height.
In the utility model, band rib monolithic circular coal yard structure strengthens the rigidity of barrel by arranging ring rib, reduce the impact by local coal piling, asymmetric coal piling and differential settlement, and by part hoop tension by barrel steering ring rib, the crack width of barrel is easily controlled.Meanwhile, under the effect of ring rib " hoop ", the radial displacement at perpendicular rib and barrel top can be controlled effectively.
