National standard electrical installation atlas
1. Building electrical installation engineering atlas: design and construction materials first episode (second edition), JD10-103. as shown below, the atlas can be found on the Internet, but you can leave your mailbox number if you can’t find it.
2. G101-3 concrete structure construction drawings, plane integral representation drawing rules and structural details, (independent foundation storage strip foundation storage raft foundation storage pile foundation), page 93.
3. Yes, “16D707-1 Seismic installation of Building Electrical facilities” is a national building standard design atlas. According to the Code for Seismic Design of Mechanical and Electrical Engineering of buildings GB 50981-2014, the basic seismic requirements, key points, selection and installation of seismic supports and hangers for building electrical facilities are clearly defined.
4. Jd10-102The definition is not very good, as shown in the following picture, there should be no problem after downloading, and nothing clearer can be found on the Internet.
How to install the lamps in the steel structure factory building
I have also done such factory lighting installation, at that time I dealt with it like this, fixed with 25m2 steel strands at both ends with flower basket screws, calculated the height first according to the provisions of the drawings, the line was laid through pvc pipes, and the lamps were disposed of. I don’t know if your owners agree or not, this is more time-saving and labor-saving.
If the preliminary design is not taken into account, this has to be designed according to the required brightness combined with the window of the factory building and the roof lighting belt. (usually) the factory building with a height of 9 meters is usually enough with a 200W chandelier of 50 square meters. This is the easiest way to install and look at the picture.
First buy a special hook, then fix it on the ceiling, then install the lamp boom under the ceiling, and finally hang the steel ceiling and fix it. In addition, an independent hanger is set up, which can avoid the phenomenon of cracking and deformation of the hanging surface.
In the top installation, try not to suction top installation, the distance between the upper side of the lamp and the ceiling should be more than 200 mm. When hoisting, the metal suspender or chain should be used, and the upper end of the boom or chain should be fixed on the building structure.
The steel wire pulling rope of the column section is used as the carrier, and the lighting circuit and lamps can be attached to it. Do not destroy the original steel structure.
Tools such as ladders, screwdrivers, tape and impact drills should be prepared before installation. These tools must be used, and then you can begin to install the lamps and lanterns. If the lamps and lanterns have been installed before, remove the old lamps and lanterns and clean the surface before starting the installation. Then, turn off the power first to prevent electric shock during installation.
What are the requirements for the installation height of general lighting in the factory building
1. Lamps and lanterns should not be installed directly above the high-voltage and low-voltage distribution equipment and bus in the substation. The height of the lamps and lanterns installed outdoors should not be less than 3 meters from the ground; when installed on the wall, the height from the ground should not be less than 5 meters.
2. General open lamps and lanterns, the distance from the lamp holder to the ground is not less than the following values (except when the voltage is used): (1) outdoor: 5m (installed on the outdoor wall); (2) factory building: 5m / 3) indoor: 2m / 4) the lamps and lanterns with the hoist of the soft cable are 0.m after the cable is unfolded.
3. According to the “Urban Road Lighting Design Standard (CJJ45-2015)”, the relationship between the light distribution type, layout and installation height and spacing of lamps and lanterns in Table 3 is as follows: Weff refers to the effective width of the road surface; the distance between S lamp poles; H refers to the installation height.
4. It shall be carried out in accordance with the regulations of the National Electrical installation regulations. You can participate in the designated legal low-voltage electrician training to get the specific application size details in the detailed regulations.
