The quality acceptance standard of each project in the hardcover project!"},"content":{"rendered":"

Construction quality acceptance work permeates all aspects of the project process, including the quality acceptance of the construction process<\/strong><\/a> and the quality acceptance<\/strong> of the completion of the project in two parts.<\/p>\n\n\n\n

The quality acceptance of the construction process is roughly divided into hydropower acceptance, waterway acceptance, waterproof acceptance, carpentry acceptance, tile acceptance (including masonry project, plastering project, wall brick acceptance, floor tile acceptance), oil industry acceptance, and wallpaper acceptance.<\/strong>  <\/p>\n\n\n\n

Why quality acceptance?<\/strong><\/p>\n\n\n\n

Most of the construction steps are irreversible, even if you can redo, but also to consume excess human, financial and material resources, for the realization of business objectives and quality objectives are very unfavorable.<\/strong>  

<\/p>\n\n\n\n

What’s more, after the completion of the project can not be reviewed the hidden engineering parts,<\/strong> after concealment, if found that there are quality problems, but also have to re-cover and cover-up, will cause rework and other very large losses,<\/strong> so must do a good job in the construction of quality acceptance work.<\/p>\n\n\n\n

so<\/p>\n\n\n\n

For example, when the acceptance of hydropower projects, what are the circuit laying standards?<\/strong><\/p>\n\n\n\n

Waterproof engineering, waterproof layer height, closed water test length how long to meet the acceptance criteria?<\/strong><\/p>\n\n\n\n

Wall engineering, the same wall empty drum brick floor is the lowest number of pieces?<\/strong><\/p>\n\n\n\n

Today, the small editor and we come together to learn about hardcover construction quality acceptance standards<\/p>\n\n\n\n

01<\/em><\/strong><\/p>\n\n\n\n

Water and electricity acceptance<\/strong><\/p>\n\n\n\n

Hydropower construction is an extremely important part of the decoration, from the material purchase, strong and weak power trend, pipe slotting, and other details are testing the team’s construction level, related to the owner’s future residence convenience, comfort, and safety.<\/p>\n\n\n\n

The quality acceptance of hydropower construction is mainly carried out from the following aspects:<\/p>\n\n\n\n

1, the<\/strong> new indoor assembly box set leakage protector (current \u226430MA), the total switch using the bipolar switch.<\/p>\n\n\n\n

2,<\/strong> distribution box ground wire, zero wire using wiring row, the same terminal on the wire connection is not more than 2.  <\/p>\n\n\n\n

3,<\/strong> indoor new circuit separation laying, air conditioning, kitchen, bathroom, ordinary sockets, lighting power supply, and larger than 3KW electrical appliances should be a separate circuit.<\/p>\n\n\n\n

4,<\/strong> line diameter meets the requirements, lighting 2.5mm2, ordinary socket 2.5mm2, kitchen, air conditioning 4.0mm2, A single-circuit air conditioning hang-up is available at 2.5mm2.<\/p>\n\n\n\n

5,<\/strong> ground wiring point to point laying, bright-line horizontal vertical.   (point-to-point).<\/p>\n\n\n\n

6,<\/strong> wires must not be directly buried in the wall or ground, must have protective measures. When reinforced concrete walls and top surfaces cannot be piped, they are protected by 3-point or yellow tubes.  <\/p>\n\n\n\n

7,<\/strong> wall wire pipe slotting depth is not less than the tube diameter plus 15mm, slotting width than the outer diameter of the tube is 10mmlarger.<\/p>\n\n\n\n

8,<\/strong> wall, ground wire pipe side by side,  wire pipe spacing 10-20mm.<\/p>\n\n\n\n

9,<\/strong> walls, ground wire pipe with cement mortar or copper wire fixed, spacing is not greater than 1000mm.<\/p>\n\n\n\n

10,<\/strong> ceiling wires must not be exposed, lamp headline plus hose protection, split box to have cover protection. The ceiling inner tube is secured with a hook or tube card and does not space more than 1000mm.<\/p>\n\n\n\n

11,<\/strong> wire pipe and distribution box, wire box using latch connection, (hose into the wire box, dark box, and dark box connection also need to use the wire pipe transition.<\/p>\n\n\n\n

(1) The wire box is connected to the wire tube using a latch.<\/p>\n\n\n\n

(2) The line box uses a protective box.<\/p>\n\n\n\n

12, <\/strong>PVC wire fittings brush PVC special glue, not loose.<\/p>\n\n\n\n

13, <\/strong>PVC wire pipe bending using a matching special elbow spring, there must be no wrinkles.<\/p>\n\n\n\n

14,<\/strong> bathroom floor does not allow the laying of wire pipes (subject to structural restrictions can not walk the top of the wall except).<\/p>\n\n\n\n

15,<\/strong> strong and weak power is strictly prohibited with the tube and the same back box laying, video, and network lines can be the same box.<\/p>\n\n\n\n

Water and electricity are in the same tank<\/p>\n\n\n\n

16,<\/strong> strong and weak wire pipe cross, wrapped in paper to do shielding anti-jamming measures.<\/p>\n\n\n\n

Weak power uses tin paper for anti-jamming treatment<\/p>\n\n\n\n

Strong and weak power did not do anti-jamming treatment<\/p>\n\n\n\n

17,<\/strong> wire and gas pipes, water pipe spacing (the same plane \u2265100mm, different plane \u226550mm).<\/p>\n\n\n\n

18,<\/strong> wire pipe and gas water heater exhaust pipe distance \u2265 150mm, not satisfied should take isolation measures.<\/p>\n\n\n\n

19,<\/strong> the new electrical switch, socket, and gas pipe spacing \u2265 150mm, not satisfied with the isolation measures should be taken.<\/p>\n\n\n\n

20,<\/strong> the distance between the strong power and the weak panel must not be less than 300mm (except where the actual installation conditions are limited).<\/p>\n\n\n\n

Strong and weak wire box spacing 30  centimeters<\/p>\n\n\n\n

21, the<\/strong> same wall switch, socket panel level difference \u22643mm.<\/p>\n\n\n\n

22, <\/strong>adjacent socket back box or panel out of the wall height is consistent, the backbox between 10mm spacing and filling.<\/p>\n\n\n\n

23,<\/strong> the same residential wiring color should be uniform, phase line (L) should be red, zero line (N) should be used in blue or black, ground protection line (PE) must be the yellow and green two-color line.<\/p>\n\n\n\n

24, the pipe wire cross-sectional area does not exceed <\/strong>40% of the pipe diameter cross-sectional area, such as:<\/p>\n\n\n\n

The  6-tube each cross-wires \u2264 3 (4mm2) or 5  (2.5mm2) or 8  Root (1.5mm2);<\/p>\n\n\n\n

Each of the 4 tubes \u2264 3  (2.5mm2) or 5  (1.5mm2).<\/p>\n\n\n\n

25,<\/strong> the wires in the tube shall not have kinks and joints.<\/p>\n\n\n\n

26,<\/strong> the wires in the tube must be able to be pumped, easy to repair and replace later.<\/p>\n\n\n\n

02<\/em><\/strong><\/p>\n\n\n\n

Waterway acceptance<\/strong><\/p>\n\n\n\n

The main points of acceptance of waterway construction quality are mainly reflected in the installation of hot and cold water supply and drainage lines and the installation of interfaces of different lines:<\/strong><\/p>\n\n\n\n

1,<\/strong> water pipe laying follows the principle of electricity underwater, not axial distortion.<\/p>\n\n\n\n
