Abstract
The utility model discloses a column-foot bottom plate of a large power station boiler. Since the CE technology is introduced in 1980s, a column-foot structure adopts a design method in American steel structure specifications and adopts a separated type column bottom plate structure. A column bottom plate designed according to the structure form is thick, and material purchase is not easy. Especially, as units with supercritical 600MW and more than supercritical 600MW are increased, the bearing force of a column bottom plate is increased, the column bottom plate is thicker, and the maximum thickness of the column bottom plate reaches 240mm. On the existing steel market, steel plates thicker than 120mm need to be reserved, the purchase period is up to one year, and thus the supplying requirement can not be met. The column-foot bottom plate comprises a bottom plate (1), wherein the side surface of the bottom plate is provided with three adjusting bolts (2), and a group of horizontal stiffening rib plates A (3) and a group of vertical stiffening rib plates B (4) are welded on the bottom plate. The column-foot bottom plate disclosed by the utility model is used for supporting an H-shaped or box-type column body.
Description
technical field:
the utility model relates to a kind of suspension column base plate of large-sized station boiler.
background technology:
since early eighties is introduced CE technology, suspension column structure is the method for designing adopting in U.S.'s norm of steel structure always, adopts " separate column base arrangement ".But the column base plate thickness by the design of this form of structure is thicker, has brought larger difficulty to material purchases, the increasing of especially overcritical 600MW and above unit, due to the increase of the bearing capacity of column base plate, the thickness of column base plate is thicker, and maximum ga(u)ge has reached 240mm.In current steel market, steel plates more than 120 mm will carry out scheduled purchasing, and procurement cycle reaches 1 year, cannot meet the requirement of the supply of material.
utility model content:
the purpose of this utility model is to provide a kind of suspension column base plate of large-sized station boiler.
above-mentioned object realizes by following technical scheme:
a suspension column base plate, its composition comprises: base plate, the side of described base plate has three adjusting bolts, is welded with one group of horizontal put more energy into floor A and one group of vertical floor B that puts more energy on described base plate.
beneficial effect:
1. column base plate thickness of the present utility model can be controlled in 120mm, and procurement cycle can guarantee; Owing to adopting " boots girder construction column base plate ", wanting of the Thickness Ratio separate type of column base plate is thin a lot, can reduce steel consumption simultaneously.Each boots girder construction column base plate at least will reduce more than 1 ton compared with the weight of separate column base plate.For overcritical 600MW and every boiler column base plate weight of above unit, can reduce more than 15 tons.
the utility model is cancelled the post pattern separated with column base plate, and the form that adopts post and column base plate to link together is big or small according to column section and column base plate bearing capacity, and by the setting floor of putting more energy into, what make that column base plate can be more uniform is delivered to power on basis.
the connected mode of a kind of the utility model and I shape post: weld with horizontal, the vertical floor of putting more energy into respectively on four edges of a wing of I shape post.
accompanying drawing explanation:
accompanying drawing 1 is front view of the present utility model.In figure, 1 is base plate, and 2 is adjusting bolt, and 3 is the floor A that puts more energy into, and 4 is the floor B that puts more energy into.
accompanying drawing 2 is lateral views of accompanying drawing 1.
accompanying drawing 3 is top views of accompanying drawing 1.
accompanying drawing 4 is structural representations of the utility model and I shape post solder bond.
accompanying drawing 5 is lateral views of accompanying drawing 4.

the specific embodiment:
embodiment 1:
a suspension column base plate, its composition comprises: base plate 1, the side of described base plate has three adjusting bolts 2, is welded with one group of horizontal floor A that puts more energy into, piece number on described base plate: 3 and one groups of vertical floor B that put more energy into, piece number: 4.Different embodiments are referring to accompanying drawing.
Claims (1)
1. a suspension column base plate for large-sized station boiler, its composition comprises: base plate, is characterized in that: the side of described base plate has three adjusting bolts, is welded with one group of horizontal put more energy into floor A and one group of vertical floor B that puts more energy on described base plate.
