Description

A kind of large-scale pipeline structure
Technical field
The present invention relates to a kind of pipeline configuration, especially a kind of large-scale pipeline structure.
Background technique
Existing pipeline material mainly includes steel pipe (such as welded still pipe, seamless steel pipe), and cast iron pipe is (such as grey mouth, spheroidal graphite cast-iron Pipe), pipe of concrete, plastic tube and composite pipe etc., however these pipelines need to could have by handling its outer wall The performances such as certain anti-corrosion, moisture-proof, antiseepage.
In addition, above-mentioned pipeline have the defects that it is certain.First, the weight of steel pipe, cast iron pipe and pipe of concrete is all very Greatly, especially large-scale pipeline, is unsuitable for carrying, time-consuming and laborious；Second, fabrication cycle is long；Third, anti-pressure ability are poor；4th, it protects Temp effect is poor；5th, vibration resistance is poor；6th, heat insulation effect is poor.
There are also existing using pipeline made of cellular board, cellular board includes upper and lower panel and honeycomb core, to improve light Quantization.However honeycomb core be linked into an integrated entity by multiple honeycombs, and the top and bottom of honeycomb core and upper and lower panel it Between carry out line contact, the problem of will lead to honeycomb core and upper and lower panel in brazing process the welding is not firm, it is easy to generate gap Or cavity etc., and then causing overall structure unstable, intensity is low, anti-impact force difference etc..
Summary of the invention
One kind is provided from heavy and light the purpose of the present invention is overcoming the above-mentioned insufficient of the prior art, and intensity is big, high temperature resistant, resists Vibration, sound insulation and noise reduction, stable structure, large-scale pipeline structure with long service life.
The technical scheme is that a kind of large-scale pipeline structure, including pipeline body, the pipeline body is by least two Block metal plate is spliced to form；The metal plate include first panel, second panel and be set to first panel and second panel it Between multiple hollow pipes, between hollow pipe and first panel, second panel be equipped with articulamentum；At least one end of hollow pipe is equipped with and turns over Side.
The invention has the following advantages that (1) large-scale pipeline structure is spliced by metal plate, compared with prior art, Under equality strength, materials are minimum；Under equivalent weight, maximum intensity.This is because: first panel and second panel are by stress After can be dispersed on each hollow pipe, laterally and vertical applied force is small, be unlikely to deform, to reduce the integrated stress of metal plate, into And increasing the integral strength and stability of structure, anti-impact force is strong, long service life.(2) present invention can collect metal plate Middle transport, and splicing is concentrated, time saving and energy saving, work efficiency is high.(3) presence of hollow pipe substantially increases lightweight.(4) pass through Flange is set on hollow pipe, and the bonding area being capable of increasing between hollow pipe and panel improves integrally-built intensity and steady It is qualitative, structural intergrity can be kept under stress.Wherein, flange of the invention refers to the contact surface on hollow pipe, with Increase the contact area between hollow pipe and panel, the shape of contact surface is not especially limited.(5) pass through first panel, second Panel is sealed the upper and lower side of hollow pipe, forms the confined layer of larger space, greatly improves sound insulation and noise reduction effect.(6) it spells The dress period is short, high-efficient.(7) once there is one piece of metal plate damage, only this part metal plate can be replaced, other metal plates Unaffected, flexibility ratio is high.
In above scheme, so-called large-scale pipeline refers to the biggish pipeline of volume, such as outer diameter tube >=30cm.If osculum The pipeline of diameter uses structure of the invention, will lead to cost and greatly improves.
Further, the articulamentum is brazing layer or resistance layer.By soldering or electric resistance welding, overall structure can be made It is more uniformly stressed, overall structure is more firm.
Further, the cross sectional shape of the pipeline body is the round or side N shape, N >=3.
Further, the multiple hollow pipe is the hollow pipe with flange；It or in multiple hollow pipes include with flange The hollow pipe of hollow pipe and not set flange.The quantity of the hollow pipe of not set flange preferably account for hollow pipe sum 1/3 hereinafter, To guarantee the integrally-built strength and stability of metal plate.
Further, the flange is the contact surface to turn up along hollow tube end or flange along hollow tube end varus Contact surface.
In addition, flange of the invention can also be integrally formed contact surface, if flange is by hollow duct occlusion；It is also possible to Spaced contact surface, such as symmetrical at least two is semicircle, at least two symmetrical bar shapeds or other are different Shape structure, such as it is petal；Flange is also possible to the contact surface etc. routed up and bent downward along hollow tube end level.Above-mentioned The turnup structure of meaning can increase the bonding area between hollow pipe and panel.
Further, hollow pipe can be enclosed construction, hollow structure or semi-closed structure etc..Such as: enclosed construction Can be inner cavity is hollow, end-closed structure, and wherein end-enclosed also belongs to a kind of structure of the application flange varus, example The enclosed construction that flange as the aforementioned is sheltered from the end of hollow pipe by varus.Semi-closed structure can be hollow pipe Inner cavity is semiclosed, and the tube wall for being also possible to hollow pipe is semiclosed, such as the lesser slot in one of gap is opened on tube wall, or in sky Multiple holes are opened up on heart pipe.
Further, the cross sectional shape of the hollow pipe is round, ellipse or the side N shape, N >=3.The side N shape can be triangle Shape, rectangular, pentagon, hexagon, heptagon etc..
The structure of hollow pipe has the advantage that first, can greatly improve lightweight；Second, the addition of hollow pipe is protected Card first panel and second panel can be evacuated by after stress by hollow pipe, so that the entirety for reducing metal plate is answered Power, and then increase the integral strength of structure, so that above structure has the following characteristics that under equality strength, weight is most light；Same weight Under amount, maximum intensity；Third carries out sealed with brazing to the upper and lower side of hollow pipe by first panel, second panel, is formed larger The confined layer in space, greatly improves soundproof effect.
The preferably circular hollow pipe of hollow pipe, have many advantages, such as uniform force, be unlikely to deform, stability it is high, and make work Skill is simple, low in cost.When hollow pipe is N deformation type, number of edges of the preferably N greater than 4, N is mostly closer to circle hollow pipe, no It is easily-deformable.
Further, the first panel and second panel are surface plate or curved slab or a panel is surface plate, another Panel is curved slab；Or first panel and/or second panel are with corner.
The line style of curved slab can be arc, waveform etc..When first panel and second panel are the curved slab of arc When, the radian of two panels may be the same or different.The shape of surface plate can be set as needed.Panel band turns Angle, which refers to, extends another plate body at an angle with the panel at the edge of panel, and hollow pipe is also added on the plate body, passes through Integral braze-welded metal plate of the formation with corner.
Further, the material of the first panel and/or second panel is stainless steel, carbon steel, titanium or alloy sheets.Alloy can To be copper alloy, titanium alloy etc..First panel and second panel are preferably made of heat-resisting material, can be played fire prevention etc. and be made With.Certainly, above-mentioned material is only several preferred embodiments of the invention, does not limit material of the invention.
