➤ Material requirements

PVCTube

• Outside the pipe is smooth,Ballile recess、Pinhole、bubble,Internal and external trails should comply with national unified standards,The thickness of the pipe wall should be uniform

(16 swg brass tube)• Insulation catheter accessories and formulated products,Such as various lamp boxes、switch box、Socket box、Tube、Adhesive, etc.,The length of the casing should be satisfied with the outer diameter of the tube3Multiplication,And should use a set of flame retardant products

(16 swg brass tube)• The tube wall of the flame retardant plastic tube should be thin and uniform.,No bubbles and body deformation, etc.;Darkness, such as design, no requirement, no medium or more catheter

KBGTube

• Line pipe、Outer wall smooth,No obvious bubble、Crack and uneven defects;There is no ribs and similar defects in the inside and outside surface.;The edge of the mouth is smooth,No damage、Cable insulation;KBGThe steel pipe should be brighter inner and outer walls.、Uniform,No breakage

• Pipe wall thickness、Internal and external diameters should be uniform

JDGTube

• Model specifications meet the design of the product identification of the surface of the pipe

• Metal inside and outside wall coatings are uniform and have no flakes、Rust and other phenomena

(16 swg brass tube)• Pipe connection sleeve and its metal accessories inner and outer wall surface smooth burr、Fly、Sand eye、bubble、crack、Deformation and other defects

• Pipe connection sleeve and its metal attachment wall thickness uniform tube edge flat smooth,Tightening screws in line with product design requires a good thread and smooth cooperation

(16 swg brass tube)• Pipe wall thickness、Internal and external diameters should be uniform

(16 swg brass tube)• Conduct without severe rust

• Locking nut shape is intact,Silk buckle,No warpage deformation

• Pipe diameter of the catheter、Wall thickness and uniformity

Interpretation of the Military Buried Process


➤ Line box prefabrication

The usual practice is before concrete pouring,Filling wood chips with tape。

➤ Substation

(16 swg brass tube)Accurately measure the position of the lamp position according to the construction drawings and the specified requirements,The size of the light space box with the paint is used and the direction of laying the light space box pipeline。

The impact of the positioning of the beam plate is not accurate on the post-installation:

• Line box is not in

• The cable box is not in a line

• Mixed line

• Beam Bottom Tube and Wall Map

Problem example:

➤ Cutting

Frequently Asked Questions and Precautions in Line Management:

• Dimensions must be precise when taking pipe:Due to the length of the length,In order to save trouble when construction,When the pipe is polarized, the line tube is overall.,In order to be connected when the line tube is shorter,Put the connector does not leave the length,It is prone to gap or fall off at the joint.。

• Pipe pipe mouth glitch:Due to use tools or methods are not suitable,Many times, do not equipped with round files when making,Pitch burrs is not in place,Leading the joint installation difficulties,Easy to damage the wire insulation when threading。

• Tube bending quality:Different types of pipes are bent at the scene,The tool or method used in the eluator is not suitable,More is even directly with foot or card on the steel bar,Or elongated radius is too small。This is easy to cause wire tube bending。

Problem example:

(16 swg brass tube)Cutting the tube mouth is quite,No burr、Sharp edge,Welding is full of welds、seal,Remove welding slag,Anti-corrosion treatment is required during darkness in the concrete,Do not do anti-corrosion outside。

Wire tube material、Specification、model、Size must choose correct。


16 swg brass tube


(16 swg brass tube)The line tube is too short


Cracks or significantly concave phenomena after the lead tube bent。The bending radius of the line pipe is not less than6D,There is only one bend between the two online boxes.,not less than4D。The elbow should not exceed3each,Right angle bending must not exceed2indivual。

➤ box、Box positioning fixation

box、Frequently Asked Questions and Precautions in Box Positioning:

• Positioning is accurate:Pre-reserved hole,If the positional positioning is not accurate, it will cause the post-distribution box.、Bottom box、Lamp、Device installation has a large impact,Severely affect the effect after installation,Severe can lead to partial use functions。

• The size of the hole is to be correct:Cave mouth size is not suitable,It will cause more exclusive and repair work in later periods,And it may affect structural security when the masonry or concrete can be found.。

(16 swg brass tube)• Fixed:The line box is not firmly fixed.,Made in the reinforced concrete,The connected line pipe is loosely,More cable boxes are damaged during concrete pouring, causing the loop newspaper;During the second structure,The box and the online box are easy to tilt,Wiring difficult,Affect the appearance。

Demonstration example:

Civilized positioning control points for the pre-buried positioning control points for the basis for the predetermined positioning line box position and height,Wall column midline box and distribution box only reserve hole,Secondary structure1mLine and gray pie,The surface of the box is outside the plasma2mmBehoovery。

The wire box is installed around the installation with steel bars and is fixed and welded.;There must be a lock between the line box and the line tube.;Accurate positioning according to the civil construction standard line,And take into account the thickness of concrete protective layer。

➤ Linear connection fixation

PVCTube connection fixation

(16 swg brass tube)Point:

The line pipe must be straight,Do not insert insertion;The sleeve length is a pipe diameter1.5~3Multiplication;When the line tube sleeve is bonded, the adhesive must be applied to the tube wall and the end,The end of the tube must be closely connected and maintained at least15Do not move,Guaranteed bonding firm,Line pipe joint and both ends50mmFirm must be fixed。

SCTube connection fixation

Point:

• Welding steel pipes should be used with threaded connection and sleeve welding,It is strictly forbidden to protect the mouth-soluble connection,Using threaded connection,Sleeve,After the tube is strict,Digital dew buckle2buckle,Both ends of the connection bridge。

• Steel pipe enters the distribution box、Junction Box、switch box、When the base box,To be a sleeve lock,Connection is close,Expose2~4buckle,Taponic、Glossless。

• Pipeline,Steel pipe bending radius is not less than6D(DSteel pipe outer diameter),No obvious wrinkles in the curved,The font is not greater than0.1MultiplicationD,The bend is not greater than90º。

• In the concrete, the protective layer is not less than15mm,Anti-corrosion treatment is required。

(16 swg brass tube)• Outdoor burying cable catheter must be preserved,The depth should not be less than0.7m。Wall thickness is less than equal2mmSteel wire catheter should not be built into the outdoor soil。
