Abstract
The utility model relates to a chimney, in particular to a steel chimney structure, which comprises a chimney foundation and a steel chimney shaft wall arranged on the chimney foundation, wherein the steel chimney shaft wall adopts the shape of a cylinder with constant sections; the middle upper part outside the steel chimney shaft wall is fixed with one end of each steel supporting leg; the chimney foundation is fixed with the other end of each steel supporting leg; the steel supporting legs are circumferentially and uniformly arranged along the steel chimney shaft wall; and a steel waling stripe is arranged between the inner sides of the steel chimney shaft wall at the connection where the steel chimney shaft wall is opposite to the steel supporting legs. The steel chimney structure has the advantages that the material procurement and the processing are more convenient during the manufacturing process of a steel chimney which is in the shape of a cylinder with constant sections and the steel supporting legs; and no scrap exists during the splicing process of the cylindrical chimney, so that the purpose of saving materials is achieved. Through enhancing the rigidness of the chimney by utilizing the steel supporting legs, the natural vibration period of the chimney is reduced, and the critical wind speed of the steel chimney is improved, so that the chimney is hard to generate across-wind sympathetic vibration, thereby ensuring more reasonable chimney stress.
Description
Technical field
The utility model relates to a kind of chimney, relates in particular to a kind of steel stack structure.
Background technology
In the design of most existing steel stack conical gradual change cross section is arranged all, its shortcoming is must be cut into a lot of steel plates fan-shaped in construction, the part that will cut away when particularly adopting big block plate in order to reduce the welding job amount is more to cause waste, and manufacture difficulty is also big in addition.Also have chimney is designed to the uniform section cylindrical shape.It is not too reasonable to say from loading angle.
The utility model content
In order to solve the problems of the technologies described above, the utility model provides a kind of steel stack structure, and purpose is to make easy construction, and economical with materials is stressed reasonable.
For reaching above-mentioned purpose the utility model steel stack structure, comprise chimney raft, be located at the steel stack barrel on the chimney raft, described steel stack barrel is the uniform section cylindrical shape, 1/4～1/3 of the steel stack barrel outside is highly located to fix with an end of each steel leg, the other end of chimney raft and each steel leg is fixed, and steel leg is along steel stack barrel circumference; Between the steel stack barrel inboard of the steel stack barrel junction relative, be provided with the steel stull with steel leg.
The described suspension column pre-embedded steel slab that is connected with steel leg that on chimney raft, is provided with.
Be provided with the backing plate of putting more energy between described steel stack barrel and the steel leg, put more energy into backing plate and the weld all around of steel stack barrel, put more energy into backing plate and steel leg are weldering of edge of a wing groove and the two-sided pin weld seam of web.
Perps on described put more energy into backing plate and the steel stack barrel and the distance between the transverse joint are greater than 300mm.
Described steel leg is 4-20, is 360 degree five equilibriums in the steel stack barrel outside and evenly distributes.
Described steel leg adopts H shaped steel.
H shaped steel is adopted in described steel stull, and cross type is placed, and weld seam adopts pin weldering weld all around between steel stull and steel stack barrel inboard.
Keep inclination angle 45 degree between 60 degree between described steel leg and chimney raft.
Advantage of the present utility model and effect: uniform section cylindrical shape chimney adds the way of steel leg, cutting of conical gradual change cross section steel plate and welding in construction have been avoided, simplified the difficulty of construction, make material purchases and processing all more convenient, and do not have waste material during the splicing of cylindrical shape chimney, reached the purpose of economical with materials.Strengthen the rigidity of chimney by steel leg, improved the critical wind velocity of steel stack the natural vibration period of having reduced chimney, make chimney be not easy to take place Crosswind Vibration, make chimney stressed more reasonable.Owing to the existence of steel leg, strengthen the dynamic moment of inertia of steel stack bottom surface simultaneously, effectively reduced the chimney cycle.Make chimney structurally more safe and reliable.
