Description
Technical field
This utility model relates to a kind of ruggedized construction, and a kind of pipeline that increases allows the structure of span.
Background technology
At present, the situation that in heating system, big pipeline and small pipeline are arranged side by side gets more and more, in pipeline aerial crossing
When the facilities such as building, road, river or barrier, owing to span is relatively big, big pipeline meets span requirement
And small pipeline is when being unsatisfactory for, being individually for small pipeline sets up pedestal or arranges truss, girder steel etc., from design angle
Consideration is uneconomic.It is thus desirable to by the cross section bending resistant section coefficient and the moment of inertia that increase small pipeline self,
Realize increasing the permission span of pipeline, make big pipeline cross over the barrier of relatively large span together with small pipeline.
Chinese patent bulletin text CN103574180A discloses a kind of knot by L-type angle steel reinforced pipeline
Structure, but firm because not only not playing increase pipeline compared with small pipe section angle steel close to pipe level neutral axis position and moment of flexure
The effect of degree, also add the weight of pipeline self, and after using this structure, pipeline allows span increase inconspicuous.
Summary of the invention
Technical problem to be solved in the utility model is to provide a kind of pipe strengthening knot by band steel and floor
Structure, makes the cross section bending resistant section coefficient of pipeline self and the moment of inertia increase, thus realizes pipeline and allow span
Increase.
This utility model solves above-mentioned technical problem and be the technical scheme is that
A kind of pipeline that increases allows the structure of span, and its structure includes pipeline and girth member, described girth member bag
Including band steel and floor, described band steel is vertically connected on pipeline, and described floor one end connects band steel, the other end
It is connected with pipeline or band steel；Described girth member and the junction point at least two of pipeline.Pipeline vertically sets
Putting band steel and can make the pipeline strength of band steel position, being made by the setting of floor should suffered by pipeline each several part
Power is more uniformly transferred on band steel, also makes stress suffered by each parts of girth member be more uniformly distributed, thus adds
Cross-section of pipeline bending resistant section coefficient and the moment of inertia increase；Only need band steel vertical welding when assembling girth member simultaneously
It is connected on existing pipeline, then will weld between floor with band steel and pipeline, band steel and band steel, i.e. realize reinforcing
The installation of part, it is achieved increase pipeline with easy mounting structure at lower cost and allow span.
Further, often comprising one piece of band steel in group girth member, described band steel lateral symmetry is provided with floor,
Described floor one end connects band steel, and the other end connects pipeline.Floor one end connects the band steel other end and connects pipeline
The suffered stress making pipeline each several part is more uniformly transferred on band steel；Floor is symmetrical in band steel and arranges, and makes flat
Stress suffered by steel both sides is more uniformly distributed, thus increases band steel and the intensity of pipeline further.
As preferably, the angular range between described floor and band steel is 20 °～40 °.During angle too small, band steel
It is difficult to construction；When angle strengthens, girth member reinforcement effect reduces；It is arranged on 20 °～40 ° of easy constructions and adds
Firmware can play maximum effect.
Further, often comprising at least two pieces of band steels in group girth member, each band steel is axially arranged along pipeline, phase
Connect between adjacent band steel and have floor.Connect floor between band steel and band steel is formed supporting role, be also beneficial to raising and add
Firmware and the stability in the large of pipeline.
As preferably, described floor is vertically connected at band steel.It is optimal that floor vertically connects support effect.
Further, the depth of section of described band steel is 5～15 times of cross-sectional width.The wide pipe strengthening of band steel
Poor effect and pipeline overall weight can be affected；The too high meeting of band steel causes pipe insulation thickness additionally to increase, warp
Ji property reduces；Therefore depth of section is that 5～15 times of cross-sectional width are advisable.
As preferably, described pipeline is outside equipped with heat-insulation layer, and the thickness of described heat-insulation layer is more than or equal to girth member
Height.By heat-insulation layer wrapped strengthening part, the bulk strength of pipeline can be increased further, and increase pipeline
Aesthetics and safety.
As preferably, described conduit upper and bottom respectively connect girth member, and described girth member is symmetrical in pipeline
Vertical centrage is arranged.In the span centre part of pipeline, because pipeline bottom is away from the strong point, moment of flexure is relatively big, because of
This can reduce pipeline break at conduit upper and bottom each reinforcement by connection part and occur.
This utility model compared with the existing technology has the following advantages and effect: be vertically arranged band steel on pipeline
Can make the pipeline strength of band steel position, the suffered stress being made pipeline each several part by the setting of floor is more equal
It is transferred on band steel evenly, also makes stress suffered by each parts of girth member be more uniformly distributed, thus it is whole to add pipeline
The cross section bending resistant section coefficient of body and the moment of inertia increase；Only need band steel vertical welding when assembling girth member simultaneously
On existing pipeline, then will weld between floor with band steel and pipeline, band steel and band steel, i.e. realize girth member
Installation, it is achieved at lower cost with easy mounting structure increase pipeline allow span.By band steel body,
Band steel, pipeline and the structure such as the triangular attachment structure of floor and heat-insulation layer are arranged, increase further band steel and
The intensity of pipeline, adds pipeline and allows span.
