Abstract

The utility model discloses an embedded wire wave plastic built-in tube, wherein a preembedded pipe is adopted with a corrugated plastic pipe, and a built-in line is synchronously placed in the corrugated plastic pipe when the corrugated plastic pipe is extruded, drawn and formed by an extruder. The built-in line can be a built-in lead wire, such as a metal wire, a plastic line, a nylon fiber line, etc. The built-in line can be also a built-in functional wire, such as an electric wire and cable, a telephone communication cable, optical cable network wire, etc. Compared with a straight plastic pipe, the corrugated plastic pipe adopted is more pressure-proof, impact resistant and easy to bend. When laying out a line if using the built-in lead wire corrugated plastic preembedded pipe, the lead wire inside can be remained to draw a functional wire, which omits the complex processes of that a wire conducting device needs to be put when laying out a line, and a lead wire needs to be drawn. When laying out a line if using the built-in functional wire corrugated plastic preembedded pipe, as the functional wire has been contain within, the pipeline preembedding and the line lay-out can be simultaneously completed, which is more convenient in process. The utility model can be used for the line lay-out and preembedding in building construction.

Description

Corrugation plastic built-in conduit for wire

Technical field

The utility model relates to a kind of pre-pipe laying of plastics that circuit is used of laying, the pre-pipe laying of corrugation plastic of especially a kind of built-in lead-in wire or functional line.

Background technology

In construction, can relate to numerous circuits lays, as the electric wire circuit be laid with branch illuminating line, power line, use under high load electric line, public electricity-using circuit etc., also have the telephonic communication circuit, the closed-circuit cable television line road, the TV monitoring and controlling circuit, the laying of various function circuits such as computer lightguide cable link is covered with inside and outside building wall the sky in street for these circuits are not resembled the cobweb, in the construction in modern times, all carry out pre-buried.Pre-buried use be the pre-pipe layings of plastics, it is underground to allow the plastic tube of hollow be embedded in, and is embedded in the concrete of building, in the wall.After treating building frame completion, more various function circuits are interted in the plastic tube early stage of finishing, finish the laying of circuit.In existing technology, be to inject with the end of cable guiding device from pipe, wire head is exposed from the other end, at first be whether signal piping is unimpeded, if unimpeded will the lead-in wire with cable guiding device worn to the other end from an end of pipe, by lead-in wire pulling functional line, pass plastic tube again, reach the purpose of wiring as electric wire, telephone wire etc.Operation during this is various, workload is well imagined greatly, the especially existing pre-pipe laying of flat plastics that widely uses, and withstand voltage impact resistance is poor, in the construction collision of cement pneumatic hammer make plastic tube flat, broken or too urgent and flat because of corner, cable guiding device, lead-in wire etc. can't pass.At this moment, the length that the electrician will put in according to cable guiding device is installed, estimates the damage location of plastic tube, concrete is chiseled, found breakage to change the preceding paragraph plastic tube, allow after the link tester, concrete is repaired, the quality influence that the workload during this reaches building greatly is self-evident again.

Summary of the invention

The purpose of this utility model is exactly to use the existing weak point of the pre-pipe laying of circuit in order to overcome in the prior art in construction, designs a kind of pre-pipe laying, needn't wear cable guiding device in pre-pipe laying when laying circuit, connects line.Or when pre-buried pipeline, finish and lay the function circuit.

To achieve the above object, the utility model can adopt following technical scheme to finish: pre-buried plastic tube adopts waved plastic pipe, and when waved plastic pipe was extruded drawing and forming at plastic extruding machine, built-in line also placed in the waved plastic pipe synchronously.

The built-in line of the pre-plastics pipe laying of the built-in line ripple of the utility model indication can be built-in lead-in wire.It can be a metal wire, as alloying metal lines such as iron wire, steel wire, aluminum steels; Also can be plastic cord, plastic optical fibre line, nylon single; Or string line.

The built-in line of the utility model corrugation plastic built-in conduit for wire indication can be the build-in function line, as electric wire, cable, telephonic communication line, and TV closed antenna, visual monitor line, optical cable netting twine etc.

Build-in function line described in the utility model can be that sub-thread, bifilar or multiply are simultaneously built-in; The line that also can be difference in functionality is built in the pipe simultaneously.

Since adopted waved plastic pipe as pre-pipe laying in the above-mentioned solution, when same material and thickness, more withstand voltage, the shock resistance, flexible of flat pipe of bellows.When bellows is built-in with lead-in wire, when laying circuit, just needn't be in pipe interspersed cable guiding device, also needn't pull lead-in wire by cable guiding device, wear functional line but insert by built-in lead-in wire, make the laying circuit omit multiple working procedure; If bellows is when being built-in with functional line, then when pre-buried corrugation plastic pipeline, finish the laying of function circuit synchronously, the laying of function circuit is more simplified, omitted.It can be widely used in pre-buried the setting up of construction types of functionality circuit; And establish pre-buried, the Pu of outdoor underground line.

Embodiment

Fig. 1 looks schematic diagram as the utility model vertical profile, and it is made up of bellows 1 and built-in line 2.Bellows 1 is the plastics extruded product, extrude drawing and forming by plastic extruding machine, when extruding the bellows moulding, built-in line 2 also places in the bellows synchronously, owing to be not intermittently moulding continuously, its length can endless, generally ties up in a bundle with 50 meters, 100 meters, 200 meters or as required length, plants by the length of practicality during construction and cuts.

The built-in line of the utility model corrugation plastic built-in conduit for wire indication can be built-in lead-in wire, and built-in lead-in wire can be a metal wire, as alloying metal lines such as iron wire, steel wire, aluminum steels; Also can be plastic cord, plastic optical fibre line, nylon single etc.; Or the string line etc.As shown in Figure 2 because pre-pipe laying is built-in with lead-in wire, in the construction when laying function circuit, just can utilize the lead-in wire that is reserved in the pipe to go to spur functional line, to intert cable guiding device in the existing technology earlier and needn't resemble, also needn't pull lead-in wire, make and lay circuit and omitted multiple working procedure by cable guiding device.

The built-in line of the utility model corrugation plastic built-in conduit for wire indication can be the build-in function line, as electric wire, cable, telephonic communication line, TV closed antenna, visual monitor line, optical cable netting twine etc., as shown in Figure 3.Directly be built-in with functional line in the pre-pipe laying, promptly can have finished the laying of function circuit synchronously when pre-buried pipeline, its operation is greatly simplified, and the processing that only need make junction linking and terminal gets final product.Used build-in function line can be that sub-thread, bifilar or multiply are simultaneously built-in.The functional line that also can be several difference in functionalitys is simultaneously built-in, as shown in Figure 4, finishes the comprehensive wiring in the modern architecture.

The utility model corrugation plastic built-in conduit for wire is not done any qualification to the depth that the corrugated form in the bellows comprises ripple, though ripple be rectangle, trapezoidal, profile of tooth, circular arc type, waveform, screw-type, even the flat plastic tube with any ripple does not belong to protection range of the present utility model yet.
