The phenomenon such as wooden box can not have split, broken, the casing surface should be smooth level off, due the anti-corrosion measures; Iron box can not have concave and convex inequality defects, gray paint is brushed again after do anticorrosive processing.
2.1.3 screw: various specifications of the screw must be through galvanized processing.
2.1.4 telephone cable type and specification and cable logarithmic should comply with the design requirements, and product certification.
2.1.5 telephone line installation and wiring should conform to the requirement of design. Please refer to the section construction of piping layout process.
2.2 the main equipment:
G wire clamp, a word screwdriver, cross screwdriver, wire stripping pliers, sank, intercom line.
2.3 operation conditions:
2.3.1 telephone system pipeline, box are laying out.
2.3.2 civil metope paint spray and decoration is complete.
2.3.3 by ground lead to port, should stay civil after plaster, box fixed on ground.
3 operation process
3.1 process:
Telephone socket box installation requirement to clear the box (box), check the wire connection - > number
3.2 the phone socket, group box installation requirements:
3.2.1 socket, group box equipment should be installed firmly, position difficult indeed.
3.2.2 generally with the height of 1.5 m from ground socket; Dark outfit electrical outlet is apart from the ground is 300 mm.
3.2.3 socket installation height and position should comply with the design requirements.
3.2.4 socket position above the heating pipe, the spacing should be greater than 200 mm; Below the heating pipe, the spacing should be greater than 300 mm.
3.2.5 embedded dark outfit group box and relevant technical data are shown in table 3-40, table 3-41.
4 quality standards
4.1 ensure projects:
4.4.1 panel must be installed firmly, to accompany the building walls. Panel without the phenomenon such as splitting, warping deformation; Set of wire can not have wall crack in the oven, must do the anti-corrosion treatment.
4.1.2 wire pressure welding must be strong, right.
Inspection method: feet, observe the examination.
4.2 the basic items:
2 set of box, box should be clean without sundry, panel clean no scratch damage phenomenon.
4.2.2 telephone line in the box (box) should have appropriate allowance.
Inspection method: to observe the examination.
4.3 allowable deviation:
The same indoor socket installation height is not more than 5 mm, adjacent rows installation height is not more than 2 mm.
Test method: 'quantity check.
5 finished product protection
5.1 installation panel, should pay attention to maintain the cleanliness of the metope, ground, and shall not damage and destruction of metope and ground.
When patch 5.2 plasma live, should pay attention to protect installed panel, may not be the pollution.
5.3 the ground socket outlet of waterproof measures should be adopted.
6 should pay attention to quality problems
Not clean 6.1 box, box, box, box sundry, should be removed to keep inside and outside clean, not contaminated with mortar.
6.2 panel installation is firm, fixed screw screw fixation should be in place, make the panel surface and fixed firmly against buildings.
6.3 panel level exceed the allowable deviation, should be timely correction.
6.4 telephone reserve quantity is not enough or too much and the conductor is placed in the oven, should be in accordance with relevant requirements will wire with adequate allowance, and tie them into beam.
6.5 wire crimping not firm, firm should be required to press the wire.
6.6 wire crimping number after chaos, shall all be renumbered after careful check.
7 quality records
7.1 phone product certificate, group box and accessories.
7.2 phone and group box installation engineering, en la, self-inspection, mutual inspection records.
7.3 design changes regarding the record, record drawings.
7.4 piping and pipe threading component project quality inspection records.
