How to install the chandelier on the ceiling of the living room to be stable?
Installation of chandeliers: large chandeliers are often installed under the floor or beam of the structural layer through suspenders or slings, and small chandeliers are often installed on the joists. Connection between suspender or sling and structural layer: firstly, iron pieces or wooden bricks are embedded in the structural layer, and the wooden bricks must be firmly stressed. Buried position should be accurate, and there is enough space for connection adjustment. In order to adjust the error of embedded parts, transition connectors are set on iron pieces and wooden bricks, which can be connected with embedded parts by nailing and welding. The suspenders and slings are connected by transitional connectors. Precautions for installation: When there are multiple chandeliers under the same ceiling, the chandeliers can be installed at the same time when the ceiling is installed, so as to adjust the height and horizontal position of the lamps in time. The method of the suspender passing through the top surface of the ceiling: direct ejection method: the suspender directly passes through the top surface of the ceiling, and it is difficult to find the drilling position on the board surface during installation. You can also install suspenders first, and then find holes in the ceiling cover panel. If you are not sure, it will affect the decoration effect. Casing method: firstly, a casing hole is opened at the corresponding position on the top surface of the ceiling, and the hanger rod passes through the casing, so that the hanger rod has room for movement and is beautifully decorated. The suspender should have a certain length of thread for height adjustment. If the light box is hung under the suspender or sling, it must be noted that the chandelier is a high-grade decorative lighting hanging from the indoor ceiling. No matter whether the chandelier is hung by wire or iron, it should not be hung too low, which will hinder people's normal sight or make people feel dazzling. Take the chandelier in the dining room as an example, the ideal height is to form a pool of lights on the dining table, but it will not hinder the sight of everyone looking at each other at the dining table. At present, the hanging bracket of the chandelier has been equipped with springs or height adjusters, which can be suitable for different floors and needs. There are several types of crystal chandeliers: rock crystal cutting and grinding chandeliers, heavy lead crystal blowing chandeliers, low lead crystal blowing chandeliers, crystal glass pendant chandeliers, crystal glass die-casting cutting chandeliers, crystal glass long chandeliers and so on. Most of the crystal lamps on the market are imitation crystals, but the materials used for imitation crystals are different. Good quality crystal lamps are made of high-tech materials, and some shoddy crystal lamps even use plastic as imitation crystal materials, so the lighting effect is naturally poor. So when buying, be sure to compare carefully and identify carefully. Commonly used crystals are K5 and K9.
There is no ceiling in the living room. Can I install a chandelier?
It can definitely be installed, but it is not good to directly install a chandelier without a ceiling. The ceiling is covered with pipes and wires, which affects the appearance. I feel that the AIA ceiling I installed, coupled with their lights, will make my home look a lot better at once. It's best to install a ceiling and a chandelier.
