Abstract
A double-barreled chimney with a section-type hung steel inner cylinder comprises a reinforced concrete outer cylinder and the steel inner cylinder, and is characterized in that the steel inner cylinder is directly hung by steel hanging rods onto the outer wall of the reinforced concrete outer cylinder in a section-type manner. The structure provided by the utility model directly transmits load to the reinforced concrete outer cylinder, so that the force transmission path is short, both the steel inner cylinder and the steel hanging rods are pulled, the characteristic that steel material has superior tension is fully played, the work amount of the steel inner cylinder is less than that of the prior art, the chimney is higher and the inner diameter is larger, more steel material can be saved, and the economic benefits are rather considerable because the chimney adopting the section-type hanging steel inner cylinder saves the sum steel material of the chimney.
Description
Technical field
The utility model relates to coal-burning power plant's Steel Inner Core of Chimney.
Background technology
The overwhelming majority adopts Steel Inner Core of Chimney in the coal fired power plant at present.Chimney divides inner/outer tube, and urceolus is a steel reinforced concrete tube structure, mainly is used for bearing deadweight, the vertical and horizontal loading that maintenance, wind, earthquake etc. cause is installed; Steel inner cylinder is used for smoke evacuation, and steel inner cylinder mainly contains two kinds of form of structure at present: the one, and self-supporting steel inner cylinder structure, steel inner cylinder is omnidistance supports oneself; Deadweight is directly passed to the basis via the steel cylinder stack shell; At interval platform is only shaken in a determining deviation setting in the steel concrete urceolus, steel inner cylinder except that being conducted oneself with dignity, the steel concrete urceolus bear that wind carries, also very big to its active force when geological process, additional bending moment; Because these loadings self are born by the steel cylinder barrel; And the barrel pressurized, so barrel is thicker, the engineering quantity of steel inner cylinder self is bigger.The 2nd, integral hanging or segmentation suspension steel inner cylinder structure; A determining deviation is provided with the steel platform at interval in the steel concrete urceolus, and steel inner cylinder is suspended on the steel platform, and the girder steel of steel platform is supported on the steel concrete urceolus; The loading of steel inner cylinder is reached the steel concrete urceolus, bear by it.This kind form of structure has been considered the characteristics that the tensile property of steel is superior, and steel cylinder is drawn, and barrel is thinner, so the engineering quantity of steel cylinder self is little than the self-supporting scheme.But the diameter of steel concrete urceolus is bigger usually, and the girder steel span of steel platform is also just very big, and the loading of steel inner cylinder also acts directly on the girder steel, and girder steel is a flexural member, and the section of girder steel is very big, and the engineering quantity of whole steel platform is very big.More than two kinds of scheme costs all very high.
Summary of the invention
The purpose of the utility model provides a kind of segmentation suspension type Steel Inner Core of Chimney of easy construction, to practice thrift steel, reduces the investment of chimney.
For realizing above-mentioned purpose, the utility model provides segmentation suspension type Steel Inner Core of Chimney, comprises a steel concrete urceolus and steel inner cylinder, it is characterized in that directly the steel inner cylinder segmentation being hung on the steel concrete outer tube wall through the steel suspension rod.The structure of the utility model directly reaches load on the steel concrete urceolus, and Path of Force Transfer is short prompt, and steel inner cylinder and steel suspension rod are all drawn, and have given full play to the superior characteristics of steel examining tensile behavior.The adjustable length of steel suspension rod own is to adapt to the error in the construction.Interval one determining deviation is provided with the steel platform in the steel concrete urceolus, but these steel platforms only are used for only rolling and repair and maintenance, and steel using amount is little.
The utility model connected node is simple, and it is very convenient to construct.The suspension type chimney has overcome the shortcoming of self-supporting and suspension type chimney, and the engineering quantity of steel inner cylinder is much littler than the self-supporting scheme, and steel platform engineering amount is much littler than the suspension type scheme.With 240 meters of chimney heights, two steel inner cylinders, the internal diameter of each steel inner cylinder are 7 meters and are example (this example is a present 600MW level unit chimney commonly used); Adopt segmentation suspension type scheme to compare, can save about about 400 tons of steel, with adopting the suspension type scheme to compare with the self-supporting scheme; Also can save about about 180 tons of steel; Chimney is high more, and internal diameter is big more, and the steel material of saving is just many more.So the total rolled steel dosage that adopts segmentation suspension type Steel Inner Core of Chimney to save chimney, its economic benefit is considerable.
Description of drawings
Fig. 1 is the layout plan of suspension type Steel Inner Core of Chimney, is pipe in two steel among the figure;
Fig. 2 is the annexation sketch map of steel suspension rod and steel concrete urceolus and steel inner cylinder.
Legend: 1, steel concrete urceolus, 2, steel inner cylinder, 3, steel inner cylinder outside horizontal stiffness ring, 4, the pin hinge, 5, the steel suspension rod, 6, the suspension rod take-up device.
The specific embodiment
As depicted in figs. 1 and 2; Two steel inner cylinders are set in the steel concrete urceolus; Be connected the fixing circle horizontal stiffness ring in corresponding position with the steel suspension rod at steel inner cylinder stack shell outer wall, fixing 3 pin hinges on the rigidity ring, corresponding fixing 3 pin hinges on the steel concrete outer tube wall; The steel suspension rod is connected between urceolus pin hinge and the steel inner cylinder pin hinge, is useful on the suspension rod take-up device of adjustment length on the steel suspension rod.Each steel inner cylinder of present embodiment is provided with horizontal rigidity ring of twice and steel suspension rod.Steel inner cylinder is sectional making at the scene, is about 6 meters one section, is welded to connect then; Progressively push up to design height through the mode of pneumatic jacking; The suspension rod take-up device is used for adjusting the length of steel suspension rod, and to adapt to the error of construction, steel inner cylinder just is installed in the steel concrete urceolus very easily like this.
