Anonymous users2024-02-06<> construction plan of building electrical lighting installation project is very important, the formulation of the plan is to better solve the practical problems, and the implementation of each construction detail can ensure the quality of the construction of the barrier and meet the expected standards. Zhongda Consulting will introduce the construction plan of the building electrical lighting installation project.
Chapter 1 Rigid flame retardant plastic pipe laying process standards.
This process standard is applicable to the installation of lighting wiring indoors or places with corrosive media such as acid and alkali (shall not be laid in places above 40 and places that are susceptible to mechanical impact, collision and friction).
Section 1 Material Requirements.
All flame-retardant (PVC) plastic pipes used should be made of flame-retardant and impact-resistant plastic pipes, and their oxygen index should not be less than 27% of the flame retardant index, and there should be a verification inspection report and a product travel factory certificate.
The outer wall of the flame-retardant plastic pipe shall have continuous flame retardant marks and the manufacturer's factory mark with a spacing of no more than 1m. The inside and outside of the tube should be smooth, without ridges, depressions, pinholes, and bubbles; The inner and outer diameters should meet the national unified standards, and the thickness of the pipe wall should be uniform.
The flame-retardant plastic pipe accessories used and the flame-retardant plastic products used, such as various lamp head boxes, switch boxes, junction boxes, socket boxes, pipe hoops, etc., must use matching flame-retardant plastic products.
The adhesive must be made of products that are compatible with flame-retardant plastic pipes, and the adhesive must be used within the expiration date.
Section 2 Main Equipment.
Pencils, tape measures, levels, tape measures, rulers, angles, sinkers, small lines, pink bags, etc.
Hand hammers, chisels, hacksaws, saw blades, knife saws, semi-circular files, live wrenches, ash buckets, buckets, etc.
Pipe bending spring (referred to as bending spring) pipe shear, hand drill, drill bit, pressure case, bench drill, etc.
Electric hammers, hot air blowers, electric stoves, hole openers, insulated gloves, tool bags, tool boxes, simmering pipes, high stools, etc.
Section 3 Operating conditions.
When cooperating with the construction of concrete structure, according to the design drawing, the pipes and various embedded parts are pre-laid in the beams, slabs and columns.
When cooperating with the construction of brick structure, large embedded parts, angle steel brackets and pipes are pre-embedded.
Before decoration, according to the civil engineering level, plastering thickness and pipeline direction, according to the design drawing, the elastic line pouring embedded parts and stable installation angle steel brackets.
After the spraying is completed, the pipeline and various boxes and boxes can be installed, and the pipeline pollution should be prevented.

Process: construction preparation with civil engineering pre-embedding civil structure reinforcement, box stable installation, concrete pouring, box cleaning, pipe sweeping and leading open piping, secondary piping, distribution box installation, trunking installation of each system through cables, wiring and insulation telemetry, equipment wiring and appliance installation, electrical commissioning and operation, completion.
2. Pay attention to construction specifications.
Ordinary lighting has a live wire and a neutral line and a grounding wire, set up a switch on the live wire, you can control the working state of the lamp, emergency lighting (lamp with battery and emergency controller) in addition to the above-mentioned wires, also need to add a battery charging line, this line is generally drawn from the other control switch, usually uninterrupted, will not be controlled by the general lighting control box circuit control switch and the on-site wall switch. When the charging cable switch is powered off, the emergency light is lit. This emergency lighting mode is usually called the decentralized emergency lighting system, now the more important building, the whole lighting system is powered by dual power supply, so as to increase the reliability of power supply, as long as there is any circuit power supply, the emergency lights are working in the normal lighting state, only when the two power supplies are out of power or in the case of fire cutting non-fire power supply, the charging cable also loses power, the emergency light works in the emergency state.
The base surface is treated first, and then the base treatment agent is painted, the base coating, the polyester cloth is laid, the secondary base coating, the surface coating is painted after the surface is dry, the secondary surface coating, and the construction process of one cloth and five coatings can eliminate the leakage problem of the color steel roof.
The intelligent lighting system uses a lighting control panel and a lighting controller to create the effect we want, such as the lighting effect of watching TV when watching TV, the birthday banquet has the effect of a birthday party, the festival has a festival effect, and it can automatically adjust its illumination according to the time.
The bridge is mainly composed of three parts: the substructure, the superstructure and the auxiliary structure, and the main construction sequence is also according to these three steps. >>>More
Before the bracket is erected, check the bowl buckle rod in advance, and shall not use digging, bending, corrosion, etc., as well as components with damage and obvious defects, and the bowl buckle or pin must use a special pin. Bowl fasteners must be inspected one by one before entering the site to see if they meet the quality requirements and design requirements. >>>More
