Abstract
The utility model relates to a three-tower-connected chimney for solar power generation. The three-tower-conjoint chimney is composed of three vertical tower bodies, a horizontal connection member and a single-tube horizontal ring beam, wherein the horizontal connection member is arranged between any two vertical tower bodies, and the single-tube horizontal ring beam is arranged on a position at the horizontal connection member level along the structural height direction. The three-tower-conjoint chimney is good in resistance strength and high in rigidity; solves the problem that an existing single-tube chimney cannot meet the height requirement of high-power thermal power generation; and subjects the connected structure to effective application to the field of solar power generation, thereby being profitable for enterprises.
Description
Technical field
The utility model is specifically related to disjunctor chimney field, is specifically related to the three tower disjunctor chimneys that a kind of solar electrical energy generation is used.
Background technology
Along with expanding economy, the solar chimney thermal power generation has solved the problem that electric power lacks, but want to reach good economic benefit, its generating scale of building the solar chimney thermal power station must reach 100MW and be only reasonably, and want to make its generate output to reach requirement, just need the chimney of high 1000M, and be applicable to the big-power solar thermal power generation.At present, so high chimney did not at home and abroad also appear, be more lower monomer structure, and existing towering conjoined structure just is applied on some building bodies, the conjoined structure that does not rationally arrange can better satisfy the requirements such as the lateral resisting, load of chimney.Wherein in the monomer chimney structure,
Steel bar concrete cylindrical shell scheme: this structural concept is the form of structure that is most widely used at present domestic and international tall and slender structure, because this scheme is as the anti-sidesway member of level, so have that the anti-side rigidity of structure is large, wind resistance is effective, resistance to capsizing is strong, cost is relatively low and construct the characteristics such as more convenient by huge shell cylindrical shell.
The mega-frame scheme: this structural concept be by the huge hollow beam spinous process of the seventh cervical vertebra of steel concrete frame as the anti-sidesway member of level, therefore have that the structure lateral deformation stiffness is little, wind loading rating is relatively poor and not enough from great high cost; But this scheme resistance to overturning is good, does not have the local stability problem.
The combining structure scheme: this structural concept is combined by encased structures and steel work, have from the characteristics such as heavy and light, lateral deformation stiffness be large, the deficiency of its maximum is the poor stability of structure, local buckling easily occurs, and there are the rigidity sudden change in encased structures and steel work intersection, may become the weak link of antidetonation, in addition, the total cost of this scheme is also higher.
Summary of the invention
Can not satisfy in order to solve existing monotubular structure the problem that high-power thermal power generation chimney height requires, the utility model provides that a species resistance is strong, rigidity large, can make structure reach three tower disjunctor chimneys of higher height.
A kind of three tower disjunctor chimneys, consisted of by three vertical monomers, level connection joint member and the horizontal ring beam of monotubular, the level connection joint member arranges between two vertical monomers of meaning in office, the horizontal ring beam of monotubular be arranged on along the structure height direction, with the position of level connection joint member equal altitudes on.
Above-mentioned level connection joint member is real abdomen contact beam, and described real abdomen contact beam is arranged in the sustained height of two vertical monomers.
The rigidity such as above-mentioned real abdomen contact Liang Shi.
The horizontal ring beam of above-mentioned monotubular is reinforced concrete circle beam, and described vertical monomer is the steel concrete cylindrical shell.
Above-mentioned steel concrete cylindrical shell is the reinforced concrete shell of Varying-thickness, and barrel thickness is linear change from ± 0.000m to+500.000m, and barrel diameter is 35m.
The beneficial effects of the utility model are:
The conjoined structure that rationally arranges has better satisfied the requirement of chimney lateral resisting, has the architectural characteristic that load-carrying construction is simple clearly, structural configuration is flexible, anti-side rigidity vertically is evenly distributed.The characteristics of this conjoined structure mainly contain following some: 1, conjoined structure is coupled together three monomer structures by connector, makes their common opposing horizontal forces, and resistance strengthens; This structure has than large space rigidity and lateral rigidity, and is highly beneficial for high-rise chimney, can make structure reach higher height.2, conjoined structure primary and secondary structure is clear and definite, has clear and definite calculation diagram and rational geological process pipeline.It is take monomer structure as main lateral resisting structure, and the connector between each monomer couples together collaborative work as ductile reinforced member with them, makes conjoined structure that clear and definite calculation diagram and rational force path be arranged, and can be good at resisting the effect of external force.3, this conjoined structure has multiple seismic-proof, has the well anti-ability of collapsing.Its force path is not unique, has the shockproof system of multiple tracks, one of them minute the destruction of system can not affect total.When the earthquake effect, if earthquake intensity is smaller, the supporting member of structure can not destroy, because this moment, structure was to be in the elastic deformation stage; If earthquake intensity is larger, in structure, plastic hinge can appear in the connector position of rigidity less, can be with the energy absorption of earthquake greatly, thus the impact of earthquake on each minute system reduced, and what reduced that total collapses under rarely occurred earthquake may.
