Description

Reduce the method for pipeline accumulation angle of turn
Technical field
The present invention relates to make to build the smooth method of interior cable pipeline.Particularly, the present invention relates in a kind of reduction building The method of cable pipeline accumulation angle of turn.
Background technique
Build in cable pipeline it is unimpeded whether, influenced by two important parameters: first is that pipeline is curved in turning Bilge radius；Second is that the accumulation angle of turn on pipeline.
One PCT application, PCT/CN2007/001172 and its British patent of the same clan, GB 2450851A and China are special Benefit, CN 101427433A, disclosing one kind makes the smooth method of cable pipeline.This invention solves the cable tube in building Realize that bending radius reaches 10 times or more of problem of caliber under the limitation of harsh execution conditions in road.Meanwhile by the invention " pseudo- stereo bent pipe " progress " rotation " operation, can reduce the accumulation angle of turn of cable pipeline to a certain extent.
Fig. 1 shows the view of " the pseudo- stereo bent pipe " an of standard, wherein the radius of curvature R of pipeline is the ten of caliber D Times or more.
Fig. 2 is the schematic diagram after this pseudo- stereo bent pipe flattening.Wherein pseudo- stereo bent pipe indicates that straight line f is with heavy line The intersection of two planes belonging to the OP section of pseudo- stereo bent pipe and OQ sections, ray m and ray n in the two planes respectively with friendship Line f is vertical and tangent with circle belonging to two plane circular arc pipeline sections, and two planes are orthogonal belonging to pseudo- stereo bent pipe 's.Here, the accumulation angle of turn of pseudo- stereo bent pipe POQ is two 90 ° of angles and that is, 180 °.
" rotation " of pseudo- stereo bent pipe can be decomposed into two steps: using ray m as shaft, the direction along ray n rotates；To penetrate Line n is shaft, and the direction along ray m rotates.The two rotate point of no order.
Fig. 3 is pseudo- stereo bent pipe in the plan view after above-mentioned " rotation " after new intersection g flattening.It should be noted that , two intersection f are shown in figure, what they reflected respectively is view location of the actual intersection f in different planes, with The intersection f that ray m intersects vertically is in the plane where pipeline section OP, and the intersection f to intersect vertically with ray n is where pipeline section OQ Plane in.By " rotation ", the part of pipeline section PPm and pipeline section QQn as " extra ".
In Fig. 3, Ψ m and Ψ n are the angle of turn of the postrotational plane bend pipe pipeline section OPm and OQn of pseudo- stereo bent pipe respectively, So accumulation angle of turn Ψ=Ψ m+ Ψ n of the postrotational live part of pseudo- stereo bent pipe.Since Ψ m and Ψ n are both less than 90 °, therefore, Ψ < 180 °.
However, the reduction for the accumulation angle of turn that can be obtained by " rotation " is constrained to physical condition, because most The restriction for the vertical deflection limiting distance that big achievable " rotation " is allowed by building body.
It will be clear that this point in Fig. 4.
In figure, straight line c is parallel with intersection f, and is a and b, the two distances respectively at a distance from rotation the first two plane It is exactly the vertical deflection limiting distance that building body is allowed.
It is substantially reduced the accumulation angle of turn of cable pipeline, it is necessary to examine each turning angle on a pipeline closely again Degree.
Summary of the invention
The local angle of turn that the present invention is exported by significantly reducing a pipeline both ends, to reduce the tired of this pipeline Product angle of turn.
Claimed method is used to reduce connection in building and is located at the cable tube between the socket of two metopes The accumulation angle of turn on road, the middle section of the cable pipeline are laid in ground, and the intersection on two metopes and ground respectively includes One pseudo- stereo bent pipe, which is characterized in that when installing the socket on metope, so that the socket and the cable pipeline pair An angle less than 90 ° is formed between the vertical line in the face and ground that connect.
Fig. 5 shows a kind of typical several embodiments for building interior pipe-line layout.The design of pipeline path uses aforementioned Method disclosed by PCT/CN2012/001172 and its patent family member.In figure, socket 101,102 and 103 is located at a face wall On, socket 100 is located on another face wall on opposite；G1 and g2 is the intersection on the two metopes and ground；W1, W2 and W3 are respectively Horizontal space between socket 101,102 and 103 and socket 100.Pipeline between socket 100 and 101 includes four sections of quarter bends Pipe, accumulation angle of turn are 360 °；The accumulation angle of turn of pipeline between socket 100 and 102 is also 360 °；And socket The case where between 100 and 103, is different, since the horizontal distance between socket 100 and 103 has been more than the 4 of turning radius R Times, that section of straight tube positioned at ground is no longer vertical with metope, so that being located at the angle of turn of two sections of bend pipes on ground, Ω 31 and Ω 32, both less than 90 °；Thus, the accumulation turning radius of this pipeline are as follows: 180 ° of 32 < 360 ° of+Ω 31+ Ω.Under limiting case, when Ω 31 and Ω 32 level off to 0 ° when, accumulation angle of turn approach 180 °.
The obtainable minimum accumulation angle of turn of pipeline and the two sockets between the socket of two opposite metopes Horizontal space W relationship it is as shown in Figure 6.Herein, ignore between socket and the interface and receptacle center of pipeline there may be Subtle spacing；The bending radius for assuming all bend pipes simultaneously is R, and pseudo- stereo bent pipe does not carry out rotation process.As W≤4R When, accumulation angle of turn is always 360 °；As W > 4R, accumulation angle of turn starts to reduce, and with the increase Step wise approximation of W 180 ° of this limiting values.
Increasing W to reduce accumulation angle of turn is the method that can be made full use of, but deliberately pursue often simultaneously It is unrealistic.
In Fig. 7, connection socket 100, bending radius are 90 ° for the angle of turn Ω 0 of the bend pipe of R.If reducing this A angle of turn, it is necessary to adjust the angle that socket 100 intersects with bend pipe.
Fig. 8 shows main improvement of the invention, i.e. the face intersected with bend pipe of socket 100 is no longer horizontal, but and ground Vertical line m form an angle Ω 1 less than 90 °；Angle Ω 1 is advisable between 30 ° to 60 °.It is worth noting that, socket from The height on ground is generally 30cm-35cm；If selecting to connect the bend pipe of socket 100 in R ≈ 30cm, Fig. 7 to be just one A 90 °.And in Fig. 8, since angle of turn is reduced to the Ω 1 less than 90 °, then also need to increase by one between socket 100 and bend pipe Segment straight tube.
Add a bit of straight tube since original 90 ° of bend pipe becomes a bit of bend pipe, it is constant in the upright position of socket In the case of, the horizontal position of socket must translate a small distance μ more；This distance can be evaluated whether out: as Ω 1=45 °, μ ≈ (√ 2-1) R ≈ 0.4R.
Fig. 9 shows the piping diagram using socket ramping techniques scheme.It can see with Fig. 5 comparison, three pipelines in figure Accumulation angle of turn all obtained significantly reducing.
The obtainable minimum accumulation turning of pipeline when 1 value of Ω is 45 °, between the socket of two opposite metopes Angle and the relationship of the horizontal space W of the two sockets are as shown in Figure 10.In W≤4R+2 μ ≈ 4.8R, angle of turn one is accumulated It is directly 270 °；As W > 4R+2 μ ≈ 4.8R, accumulation angle of turn starts to reduce, and with 90 ° of the increase Step wise approximation of W this Limiting value.
Ω1When taking different numerical value, available following correlation data (table 1):

Embodiment
Basic principle of the invention is inclined so that forming one between the face of piping connection and vertical line on the socket of metope Angle；This can be the oblique arrangement of traditional square plug receptacle or dibit rectangular receptacle, can also use new socket geometry knot Structure.
Fig. 8 shows basic embodiment prototype of the invention.The prior art of Fig. 7 is contrasted, the inclination of socket 100 makes The angle of turn obtained originally is Ω0Bend pipe become angle of turn be Ω1Bend pipe.
Fig. 9 is using the pipe-line layout after tilt schemes.Compared to Fig. 5, socket 100 arrives socket 101,102,103 The accumulation angle of turn of pipeline is all greatly reduced.When each socket uses 45 ° of inclination angles, the accumulation of every pipeline turns Bending angle can reduce 90 °.Therefore the degree of mobility of pipeline is also greatly improved.
Table 1 from Figure 10 and hereinbefore can see, with Ω1Reduction, the accumulation angle of turn of pipeline is able to double Reduce again, i.e. 2 Ω1；But the straight tube between bridge piece and socket then correspondingly becomes longer, more flat.
Figure 11 is a kind of embodiment using 45 ° of inclination angles.Five adjacent sockets 100 are divided into two rows of, arrangement after tilting At the shape of letter ' M '.It is connected between two of them socket with a bend pipe 88, referred to herein as " bypass bend pipe ".
Figure 12 shows another embodiment.30 ° of 1 ≈ of Ω, five outlets level arrangements, successively dislocation, part connect Together.There are two bypass bend pipes 88 in figure, is separately connected a pair of socket not adjacent to each other.
It should be noted that Ω130 ° of ≈ mean Ω2≈60°.The angle of turn of bend pipe for namely connecting lower right side is 60°。
The pros and cons of comprehensive various aspects, it is believed that symmetrical 45 ° are one and take into account two sides, preferred side convenient to carry out Case.
Figure 13 is the embodiment of dibit socket.Still having an angle of turn in figure is 90 ° of bypass bend pipe 88, and connection is left Right non-conterminous a pair of of socket.
The purpose of setting bypass bend pipe is current in order to facilitate the cable between socket in these embodiments above.Because The space of traditional square receptacle is limited；Cable, especially those harder, thicker cables, it is virtually impossible to swimmingly It is current.Due to not extra space, it can not also reserve some cables and be utilized in socket for future.
Figure 14 shows the crowded situation at side corner angle of cable 87 in conventional socket.In fact, the line of these " passing by " Cable 87 inevitably influences whether power outlet or the smooth installation of telecommunications outlet.
Although similar bypass bend pipe can also be supplemented in engineering outside socket, such as the bypass bend pipe 89 in Figure 15；But It is that the angle of turn of bypass bend pipe here is 180 °, and the angle of turn of the bypass bend pipe 88 in previous embodiment only has 90 °, smooth degree is not obviously in a grade.
The comprehensive aforementioned analysis to existing socket problems, it is proposed that a kind of new jack design.
The interior geometry of this new socket is made of a square space and two isosceles triangle spaces.It is whole External shape sees that new socket is the parallel hexagon of the right and left.The waist of two triangles is all the side of hexagon.Such as Figure 16 institute Show, the conventional socket 100 in left side is essentially identical to positioned at the space size of the middle part square region 1000 of the new socket on right side；Newly The upper surface of socket and the following region for respectively having a triangle, the referred to as area Guo Xian (1001 and 1002).
Figure 17 is using the pipeline embodiment part after new socket.Because of the area Guo Xian of triangle, these new sockets The reduction of angle of turn is realized without going through inclination, two bevel edges below socket have been just met for this demand.
Meanwhile the angle of turn for connecting the bypass bend pipe 88 in the area these triangles Guo Xian is also far smaller than 180 °.If three Angular is equilateral triangle, then Ω1=45 °, the angle of turn of bypass bend pipe 88 is 90 °.
The presence in the area triangle Guo Xian provides a great convenience for " the passing by " of cable.The angle of turn of cable is also big Amplitude reduces.It is difficult to the not only hard but also thick cable turned particularly with those, 90 ° are realized in narrow socket inner space Angle of turn of the angle of turn than 180 ° is much easier.
Moreover, the presence in the area triangle Guo Xian and bypass bend pipe, so that socket central space 1000 is not tied up.Equally, When needing to adjust or replacing " passing by " cable, due to having the area triangle Guo Xian and bypassing the presence of bend pipe, so that original installation Power outlet or telecommunications outlet be possible to dismantle.
