Description
Technical field
The invention belongs to indoor decoration engineering field.Especially relate to a kind of indoor electric pipe laying method.
Background technology
When electric wiring was buried in interior decoration underground, general fitment process was: earlier indoor according to the designed lines laying wire at building, after electric wire all fixes, carrying out interior decoration, and finishing material directly overlays on the electric wire.Electric wire in each exit reserved part as connecting line.Each outlet comprises switch, socket, lamp socket connection jaws etc., and the electric wire of burying underground also can be acoustic circuit, telephone wire, optical fiber etc.
Destroy metope, ground, not attractive in appearance, repair difficulty; Constructional difficulties is conflicted with former circuit generation, and particularly cross link is exposed easily because bury the more shallow crosspoint intractable that makes underground, and is also fragile after permanent the use; Damage the back maintenance difficult, after circuit is buried underground, be difficult for finding out the circuit of burying underground, will excavate body of wall when keeping in repair has certain location difficulty in the future; all lay finish after, lay and newly establish circuit and can run into and excavate difficulty, destroy metope, with problems such as former pipeline conflict.
Electric wiring is laid immediately under body of wall, ground or the finishing material, and electric wiring is subjected to the influence of chemical composition in wet environment and building and the finishing material easily and is corroded.Be embedded in underfloor electric wiring and can be twisted distortion because of the sedimentation of building, serious situation is to be torn the most; The electric appliance circuits of torsional deformation also can cause the generation of short circuit, thus fire hazardous.Be laid on electric wiring in the Stilt layer and easily run into the destruction of animals such as mouse and make the damaged or fracture of epidermis, lead directly exposes in air, because of the possibility of discharge generation spark increases greatly, easily produces fire.Electric wire also can produce breakage or fracture because of artificial destruction, particularly when finishing, carries out prior to other finishings because connect up, and after wiring is finished, when other finishings of operation, the pre-buried electric wire of easily artificial damage.Because electric wiring is embedded under body of wall, ground or the finishing material, needing to excavate body of wall, ground, finishing material after being damaged could keep in repair.Maintenance can deface finishing material, and when maintenance fragile All other routes, after maintenance, need to repair damaged face finish material, on body of wall and ground, stay the marking, not attractive in appearance.
Summary of the invention
The present invention solves the existing in prior technology electric wire to need to be embedded in the cable tubing before finishing, can't maintain and replace under the situation of not removing the face finish on the cable tubing etc. technical problem, a kind of tubing in advance is provided, after finishing interior decoration on the pipeline space, re-lay electric wire in pipeline, thereby under the situation of not removing the face finish on the cable tubing, can conveniently carry out a kind of indoor electric track laying method of electric wire maintain and replace.
Above-mentioned technical problem of the present invention is mainly solved by following technical proposals: indoor electric track laying method is characterized in that: its step comprised for three steps
1) form the pipeline space operation, the pipeline space that forms in the building indoor surface is coated by indoor hardware fitting;
2) lay operation, connect with pipeline between indoor each electric wiring outlet, pipe laying is in forming the described pipeline space of pipeline space operation;
3) the line operation is arranged on electric wire in the pipeline.
The sequence of steps that the present invention adopts is: buried pipeline in advance, and laying wire not in the pipeline carries out other decoration constructions then, and for example mason, carpenter etc. after whole fitting-out works finishes, penetrate pipeline with electric wire again.
Pipeline can be laid on the indoor any surface of building: as be laid on ground, can be in the space under the finishing materials such as timber floor or floor tile, marble tubing, the space between finishing material and ground can be filled with inserts in the laying back that finish.
