Abstract

The utility model relates to a gradual chimney comprising a reinforced concrete outer barrel and a steel inner barrel. The utility model is characterized in that: the bottom of the outer barrel is round; a plurality of floating points and steel platforms are arranged at the inner barrel from bottom to top; the inner section between the bottom of the outer barrel and the central section is shrunk along four directions and is gradually changed into four circular arcs; the rate of slope of the position of the outer barrel above the central section is zero without shrinkage. The position at the bottom of the outer barrel in one-fourth height has a table-board; the chimney section above the table-board is formed by two symmetrical straight lines and two symmetrical circular arcs; the occlusal position between the two symmetrical straight lines and the two symmetrical circular arcs has a chimney vane; the chimney vane is gradually changed to the central section from the height of one-fourth, and then is extended to the top of the chimney. The utility model has two inner barrels; the wall thickness between the outer barrel and the inner barrel is smaller gradually from bottom to top. The gradual chimney of the utility model has the advantages that: the shape is novel and the appearance is beautiful; the gradual appearance makes the chimney structure be more firm with stronger quakeproof and wind resistance capacity.

Description

A kind of gradual change type chimney

Technical field

The utility model relates to the chimney technical field, concrete relates to a kind of industrial large-scale chimney.

Background technology

Existing chimney has following two kinds of forms basically, and one is the nonvolatil fixed buildings of building with concrete or masonry, and this chimney has long service life, and the intensity height is not fragile, and surrounding environment is polluted little characteristics; But its construction period is long, and floor space is big, and in case not removable after building up, and generally only consider the smoke discharging structure problem when building, often make that this chimney profile is simple and crude coarse, inharmonious with surrounding environment, generally only be fit to do the fume extractor use of integrated mill.Its two form for building with metal tube, this structure building speed is fast, builds flexiblely, cheap, therefore uses comparatively general in midget plant; But this chimney is short service time, and perishable mashed wearing because intensity is not high, often needs to bundle safety rope, and however, blow the chimney that scrapes this structure at high wind and still collapse easily simultaneously when building, brought unsafe hidden danger to surrounding environment.

As the described chimney of Chinese patent ZL01245214.9, to form by steel pipe, concrete, the steel pipe inwall adheres to layer of concrete, and outer wall of steel pipe adheres to the anticorrosive coat of aluminium or its oxide formation, also has zinc coat between steel pipe and the anticorrosive coat.Above technical scheme can well solve the chimney anticorrosion problem, but this chimney structure intensity is little, and can only be applied in the midget plant, and the ten minutes that shows in the environment is not attractive in appearance around.

The utility model content

Technical problem to be solved in the utility model is, a kind of gradual change type chimney is provided.

In order to address the above problem, the technical solution of the utility model is such:

A kind of gradual change type chimney, comprise steel concrete urceolus and steel inner core, it is characterized in that, outer tube bottom is circular, inner core is provided with a plurality of rolling points and steel platform to the top from the bottom, outer tube bottom cross section to the mid range is shunk along four direction and is faded to four arcs, and the above slope in urceolus middle part is zeroly not shrink.

Outer tube bottom 1/4th highly locates to have table top, the above stack cross section of table top is that two symmetrical lines and two symmetrical circular arcs constitute, have the chimney wing at two symmetrical lines and two symmetrical circular arc interlocks place, the chimney wing is highly located gradual change to chimney middle part and extend to the chimney top by 1/4th.

Described inner core is two, and the wall thickness between urceolus and inner core reduces from bottom to top gradually.

Beneficial effect, the utility model gradual change type chimney, modern design, good looking appearance, the gradual change type profile makes chimney structure more firm, has very strong antidetonation, wind loading rating.

The specific embodiment

For technological means, creation characteristic that the utility model is realized, reach purpose and effect is easy to understand, below in conjunction with concrete diagram, further set forth the utility model.

Referring to Fig. 1-Fig. 6, the high 210m of a kind of gradual change type chimney of the utility model is divided into urceolus 1 and inner core 2, and urceolus 1 is a reinforced concrete structure, and urceolus 1 structure wall thickness from bottom to top reduces gradually; Inner core 2 is two steel inner cylinders, is provided with respectively at 40m, 55m, 80m, 110m, 140m, 160m, 180m, 205m and only shakes a little, and respectively at 12m, 55m, 110m, 160m, 205m the steel platform is set.

Referring to Fig. 3-Fig. 6, chimney urceolus 1 bottom is circular, makes contracture along four direction with different slopes from ± 0.000m to 110m cross section, gradually becomes four arcs, from 110m to the chimney top slope be 0.And, cut wherein two section circular arcs to the chimney top with two rectangle cross sections from 55m, thereby chimney becomes two straight lines and two sections geometric figures that camber line constitutes in this section cross section, simultaneously, both phase interlocks place constitute chimney wings 11.

Referring to contracting in Fig. 1 urceolus director 55m shaft section, form platform, add unique chimney wing moulding, make chimney integral body more be full of variety, effect in appearance, be exactly each cutting plane by the chimney central axis all curvature is totally different, modern design, attractive in appearance becomes the suburbs, city industrial construction group's a big view.

More than show and described basic principle of the present utility model, principal character and advantage of the present utility model.The technician of the industry should understand; the utility model is not restricted to the described embodiments; that describes in the foregoing description and the manual just illustrates principle of the present utility model; the utility model also has various changes and modifications under the prerequisite that does not break away from the utility model spirit and scope, and these changes and improvements all fall in claimed the utility model scope.The claimed scope of the utility model is defined by appending claims and equivalent thereof.
