Abstract

The utility model relates to a turning pipe capable of carrying out smooth braiding when a wiring pipeline turns. The turning pipe is a stereo bent pipe which can be crossed on a plane which every arc-shaped pipe segment is positioned at and is coincident at a tangent line at a wireless bonding point. An attached drawing is an effect drawing when the plane which two arc-shaped pipe segments of the turning pipe are positioned at is flattened, and the shape of the turning pipe is similar to the shape of a curve at the junction of two small fishes in a taiji drawing. By using the turning pipe, a wall corner 90 DEG tight turning which the wiring pipeline frequently encounters is changed into an arc-shaped smooth slide turning with larger turning radius, and braiding resistance is obviously reduced. The turning pipe makes the wiring pipeline smooth at the time of turning, and braiding is successful, so that many wiring pipes are used as standby can be realized and movable wiring is practised roundly to improve wiring flexibility and reach the purpose that a line can be maintained and extended and is conveniently replaced.

Description

Bending pipe

Technical field

The utility model relates to the turn fractions of wiring conduit, comprise the corner and run into door, window, post is cut off and other inconvenience by the time need to turn and cause the place of Penetrating wire for pipe difficulty.

Background technology

At routing field, the place that wiring conduit need to be turned all is to connect with elbow bend at present, and is well-known, turning like this is to be difficult to threading, must be through line in the pipe in advance, but the hidden rear wiring of pipe has just been become dead wire, increase hardly possibility of line, primary route will roll up built-in line.Wiring wants movable just can only adopt exposed conduit or wire casing, and the impact of open-wire line tube seat is attractive in appearance, and operation is difficulty also, the cloth concealed wire that only has attractive in appearance.The method of deep-cutting the foot of a wall increases radius of turn and is subjected to wall thickness degree and corner to have pillar, floor difficulty effects limit such as to dig, and practical operation is difficulty quite, and the radius of turn that provides is limited, and the threading resistance is still very big.So the concealed wire circuit of method cloth can be safeguarded with open-ended possibility little at present.

Usually it is movable that the crane span structure mode that adopts in the building seems, but line is in the groove and more than furred ceiling, and it is difficult safeguarding, expanding and change.In order to reach flexibility and reliability, usually layout in the room more and back up, wiring quantity is well beyond actual usage quantity, but it is may very fast again appearance wiring in the part not enough to enable the back, clearly that is that this is the insoluble problem of present wire laying mode because of the unreasonable distribution of point.Line is many reduction maintainability and expandability, construction is difficulty also.

Wiring at present, is generally all considered in advance for avoiding very fast backwardness owing to safeguarding, expand and changing difficulty.But along with television set, washing machine, refrigerator enter family in a large number to air-conditioning, the power line load is not much of that; TV, phone, the LAN broadband access network that dials up on the telephone, the circuit difference, be difficult to during these former sprucing up expect to obtain.Also do not have category-5 cable when beginning computer local network is arranged, generally adopt five classes and CAT5E UTP cable at present, optical fiber has arrived desktop again, but present most building probably just do not consider also dare not consider the leading amount of fiber to the desk.

Development of modern scientific technology is maked rapid progress, and technology is limited in advance, quantity leading some also do not play a role and just be eliminated, must cause waste in advance.Upgrading is except wanting a large number of expense, and also long-time, large tracts of land influences operate as normal.Leading circuit and equipment are too expensive, hesitate to discard, and keep the backwardness of can only adhering to past practices.The deficiency of conventional method wiring, all because wiring is not movable, can not satisfy can safeguard, the extendible and requirement that is convenient for changing.

Summary of the invention

For solve present wiring conduit through corner etc. is local turn after the smooth problem of threading, the utility model proposes a kind of turning method, the various shape bending pipe is provided.Substitute the elbow bend that connects when original spool is turned with bending pipe, can make pipeline unimpeded during turning, reduce the threading resistance.Adopt this bending pipe general effect so that wiring is movable, improve flexibility, reliability, maintainability, expandability and the convenient upgrading of wiring.

The technical scheme of this bending pipe is:

Pipeline was respectively walked earlier respectively one section arc when the turning method that the utility model proposes was crossed the corner turning exactly on mutually perpendicular two adjacent metopes (or floor), the docking of two sections arcs also makes abutment and wall corner line tangent, two sections pipes have consisted of the curve at two small fish junction surfaces in " S " type or the Diagram of the Supreme Ultimate, and just half arc is holded up vertical with second half.Force direction is its tangential direction on any point of arc, and identical force direction is just arranged at the abutment, and actual bending pipe is curved by a pipe, make line easily from a section of pipe through another section.The curvature of the more big then arc of radius of curvature is more little, and the threading resistance is also more little, walks this mode of arc at metope and can allow radius of curvature enough big.Making pipeline unimpeded with the bending pipe turning, cause that therefrom some wire laying modes and relevant idea change, also is its part of dealing with problems, and mainly is illustrated as an example of the office building wiring example below.

Vertical shaft is arranged in the building, and some room is far far from vertical shaft, adds at a distance on the traditional concept that turning can't make pipeline unimpeded.Through test, corner place is with the connection of this bending pipe, and pipeline is walked more than 40 meter, and to go up another face wall high more than 1 meter again from face wall relative superiority or inferiority ground more than 1 meter, and such route (having crossed two corners) has just been passed with threading apparatus is very light.Actual pipeline is straight outlet at vertical shaft, only has wall turning to ground in the room, in the room with bending pipe ground under the wall hole, afterwards to the vertical shaft remainder be straight line or the very big arc of radius of curvature basically.Look actual range and threading quantity, use bassoon with the minimizing duty ratio, or excessive at middle appropriate location opening, auxiliary again during threading with lubricants such as talcum powder.

Pipeline must be fixing, should be as far as possible under floor tile stringing the mortar layer, pipe level is arranged from the vertical shaft radial that comes out, possibility density is too big near the vertical shaft, affect the adhesive force on floor, caliber also is subjected to the restriction of flooring brick mortar thickness, and the solution of this moment is to allow a part of pipe walk this layer ground, and another part pipe is walked lower floor's terrace.When walking lower floor's terrace, need change the building structure of vertical shaft, allow the floor reduce by 30 to 50 centimetres or concordant with the lower floor furred ceiling in the vertical shaft.Handle like this and just can be routed to the nearer room of vertical shaft at this layer ground cloth tubule, caliber too hour more than stringing, to more distantly related of vertical shaft in lower floor's terrace cloth bassoon.No matter pipeline on this layer ground or at lower floor's terrace, after pipeline is completed, only need be concerned about two outlet during wiring, the centre need not to intervene.Adopt such building structure in the vertical shaft, telecommunications outlet is liftoff also to only have 30 centimetres, and cable wiring manufacture and maintenance need not to shoulder ladder.Network layout is substantially on a horizontal plane, returns the crane span structure mode that lower uses and compares with walk eminence from the lower distribution, and every line of the above floor of wiring closet is minimum can lack 5 meters.

The idea that the turning pipe is drawn is the pipeline wiring of final realization activity, need a large amount of inlet wires also can adopt the building structure identical with above-mentioned vertical shaft with the rooms such as machine room that advance thick line, rigid line, allow near a small area of ground plate of distributing frame even whole room floor all be lower than the normal terrace of lower floor, the office building floor height is generally all very high, all to occupy part space, lower floor room as the toilet, the lower floor room that can not influence machine room normally uses, or arranges the lower floor room to make other purposes.Machine room to the pipeline of vertical shaft is walked the above terrace of lower floor's furred ceiling, and pipeline is straight substantially, and can cloth much manage and back up, and can the very big pipe of cloth.

One 4 in light current circuit is in charge of to fill up and can be put down 6 Category-5 twisted pairs, and 6 are in charge of and can put down 10, advance two pipes in the general room, is in charge of that to put 6 line duty ratios be 30% for two 6, and normal room advances 6 lines should be enough.Big room or have the room of specific (special) requirements can many stringings, the room is big, and the room number also can reduce, and each floor number of tubes does not have too big variation.

Forceful electric power does not need all independent stringing in every room to vertical shaft usually, the shared leakage switch in several rooms or loop of use in parallel, only just can to nearest room from the vertical shaft stringing in such one group of room, stringing is communicated with between other room and the room, every group of room except managing vertical shaft, preferably between every group all stringing be communicated with.Normally 1.3 meters of forceful electric power switch height, socket is lower, and except lamp and ventilating fan, other line construction and maintenance are all below 1.3 meters, and it is very convenient to shoulder ladder.

Unimpeded in the time of allowing pipeline turning except bending pipe, threading is smooth and easy, more than being a conservative estimation of wiring quantity, pipe capacity and cloth tube space, is the analysis of pipeline wiring mode and remote pipe routing feasibility.Solved the outside remote pipe problem in room, household or office's internal pipeline are not long, can implement in full active routing.Bending pipe can make pipeline unimpeded, and any stringing closely in the room can a lot of Guan Yizuo backups of cloth, and bending pipe has been arranged, and stringing work just just will manage and be connected and fix, and stringing also is a nothing the matter.Below be that bending pipe is applied to room and the method for some special local wirings and the problem of solution.

1. normal room wiring.Leave on demand the wall hole in the room in the precalculated position, general liftoff 30 centimetres of power supply and telecommunications outlet, it is easy each wall hole being communicated with through the ground stringing with bending pipe.The wall hole of adjacent room is adjacent and communicate that (front forceful electric power pipe mentions that stringing is communicated with between room and the room, so that all can by another pipe get back to vertical shaft from arbitrary pipe through the room at vertical shaft, circuitous pipeline like this is in and is occupied in the wiring still for important), the pipe that comes from vertical shaft can produce a mutually redundant effect, label technique is very ripe now, can be not influential to safeguarding.

Big office, classroom, meeting room etc., the bigger desk in room is not by wall, need to draw line from the ground opening, past is used trench, upper cover movable floor brick, affect attractive in appearance, with bending pipe from wall box stringing to the floor, problem has just solved, some house temporarily when not required ground not opening also have no relations.In addition, best liftoff 30 cm of water plain cloth Guan Yizhou, can also be more than the following desktop of windowsill and below the furred ceiling each horizontal one week of stringing of height of 30 centimetres, only open when needing other opening later on a hole just can, can not have influence on other place of metope.Such provided pipe is answered the two-tube cloth together of strong, weak electricity.

2. particular room wiring.Control room, meeting room, classroom and so on big room, several distributing cabinets should be set in the room, from the vertical shaft to the distributing cabinet, enough pipelines should be arranged, whether each place that may use (wall and ground) is no matter use equal stringing now to this room distributing cabinet in the room, the two-tube cloth together of strong and weak electricity, the neglecting room-size greatly and should be able to hold distribution plants such as required switch of distributing cabinet, and distributing cabinet should have pipeline to be communicated with power cord box.Many stringings between other big room and the vertical shaft have enough pipeline wirings in order to need in the future when the room is divided into two.

3. public place wiring.The public places such as the hall all arrange big distributing cabinet, and have enough pipelines to communicate with vertical shaft, each place that may use (wall and ground) but equal stringings.These pipelines can temporarily not connect up, opening not, but its position of data logging must be arranged.These local may as later in public places eminence radio networking device is installed, the lower ground of wall (even away from) may be installed queue machine, touch-screen or the like.Also have on the roof satellite communication equipment, intercom equipment and satellite fix communication equipment etc. are installed.

Connect up between 4. outdoor and building.Outdoor pick-up head, street lamp and might use but also pipeline on the cloth of the place of being inconvenient to excavate, and be no less than two pipes.Outside run is in the underground low temperature dampness for a long time, is lightning protection, the moistureproof needs, and pipeline should outerly shield, primary insulation, and interface should be made water-proofing treatment.Also adopt the mode of pipe laying between the Lou Yulou, and enough pipelines are arranged, with bassoon and enough big radius of turn is arranged, it is excessive to establish well in the centre during distance.

Wiring idea, wiring method and concrete practice that this bending pipe is drawn, home cabling has had successful case, and remote front is mentioned and being tested, the just extension of home cabling of other wiring.All be empty in the pipe during stringing in the case, when connecting up for the first time, bedroom, study all do not have TV, network and telephone line, and the power line of cloth also is that the house is fitted up and cleaned up just threading at first.Filled afterwards the phone of telecommunications, the ADSL of Netcom online, and two computers online moved on to the study to MODEM and router from next door, gate distributing cabinet more afterwards, had very easily just solved.

The beneficial effect of this bending pipe is:

The front is mentioned in the room and is left the wall hole by the precalculated position, but grid line does not need each wall box to connect up during primary route, but only cloth to wall box commonly used just can, the minority adjustment can not affect work.In the room, reserve than the slightly long surplus line of wall hole opening part farthest in pipe, unimpeded, the surplus line of pipeline can allow position a little adjust arbitrarily in the room, can adapt to the various inner ornaments in the room, need not to reach flexibility with many wirings, circuit can be safeguarded and can back up, the fund that need not connect up and resource just can not be wasted in above the circuit more, and line has lacked simultaneously also so that the room is easier to the Penetrating wire for pipe of vertical shaft.

During primary route, the room that function is clear and definite need only connect up by actual needs; Function is indeterminate or temporarily do not have can temporarily not connecting up of demand, as storehouse; Or certain line of cloth only, as cloth telephone wire cloth grid line not.Also can be by the wiring of the most basic quantity, as estimate that there is How many people in an office with regard to how many lines of cloth, suitably increase from more distantly related of vertical shaft during the not bright first wiring assignment information point of demand, from vertical shaft than close to the room suitably reduce.Primary route quantity is seldom, is covered with another pipe of Guan Zaibu earlier, and it is empty that a pipe is in most cases arranged, and increasing wiring more later on is a thing very easily.

Circuit is extendible, and technical for some is not in the situations such as very ripe or insufficient funds, and the application system construction relevant with wiring can be implemented step by step.Cable wiring manufacture and maintenance are just carried out on particular room and two points of vertical shaft, one group has two people cooperation just can carry out cable wiring manufacture, the circuit replacement (as category-5 cable is changed into fiber to the desk) can be carried out step by step, one by one the room tear open old, renew, enable, can large tracts of land not influence operate as normal, can the normal order of public place not had any impact.

In the building use procedure, line upkeep, adjustment, increase even replacing are unavoidable.The pipeline wiring of operative activities, a professional and technical personnel looks for once constructing to two helpers again, need not to ask specialized company, and nothing but grow a bit for a long time by the time for quantity.Interim increase by one or two circuit, can be easily, solve a problem promptly.

Demand is constantly to change, and consideration fully, pipeline is sufficient, arrangement is reasonable, and the adaptive technique progress updates just stronger with the ability that quantitatively expands, and connects up more near actual needs.This bending pipe can make pipeline unimpeded, the cost of pipe is very low, many stringings are become a reality as backup (comprising unpredictable demand and the backup that can predict temporary no demand), and the flexibility of wiring, expandability and maintainability and reliability all are apparent.
