What material is used for the ceiling of large hotels? Is the wooden keel gypsum board all right? Or other materials?

With the improvement of people's living standards, home decoration has become a fashion. However, in modern family decoration, most families consider beauty and beauty, while ignoring fire safety. According to the statistics of relevant departments, at present, more than 60% of residential fires are caused by electric wire leakage.

Many home improvement owners are most concerned about whether the latex paint, paint and floor used in house decoration are environmentally friendly, have pungent smell and have good waterproof performance. And whether the ideal decoration effect can be achieved, but less consideration is given to whether the materials used in house decoration are fire-proof. For example, laying wires for decoration, most families adopt the method of burying wires. In this way, flame retardant PVC pipes are used. Because the price of PVC pipes is five or six yuan more expensive than ordinary pipes, many owners buy ordinary plastic thin pipes, which can't prevent fire once the wires leak. Many families use wood, cloth and other flammable materials as indoor decoration materials, often without fire prevention treatment, and close the ugly power switch in the room with cabinets or decorative frames, which are all fire safety hazards.

Generally, after the new house is completed, it will be audited by the fire department before it can be delivered for use. However, after the building was handed over to the owner, few people asked the owner how to decorate and transform it, and whether the fire safety after decoration was compatible with the fire design of the building.

In this regard, the following safety suggestions are put forward: First, indoor electricity is a must for every house. Before decoration, open several socket boxes to check the nozzle of the catheter. If it is aluminum wire, it must be replaced with plastic copper wire. Due to the low melting point and high resistance of aluminum wire, there are potential safety hazards, and the country has clearly eliminated it. It is better to wire the newly added power socket and lighting circuit separately, not directly from the original circuit or directly from the socket. Arbitrarily wiring or installing sockets and lighting appliances on the original circuit will cause the load of a single circuit to be too large, which will easily lead to the tripping or burning of the main power switch, and even lead to a serious fire.

Secondly, try to use fireproof materials as decoration materials, or soak flammable materials and brush them with flame retardant to meet the fire protection standards. According to records, over the years, there have been countless fires caused by neglecting decoration materials. The ceiling, in particular, is the place that causes the most fires, and it is also the place that is not easy to be found and put out. Non-combustible materials such as light steel keel and gypsum board should be used in decoration.

The surface of light steel keel is treated by hot dip galvanizing, which does not rust or deform for a long time. It is a very good fireproof and incombustible material.

However, because the traditional wooden keel contains too much water, it is easy to deform and is not fireproof, so there is no wooden keel hanging in large public places. In the past, carpentry used wooden squares for home decoration because of the small amount of work. Now, with the improvement of living standards, it is the general trend to use light steel keel, which is also used abroad.

Gypsum board should be selected with long fire-resistant time, such as Saint-Gobain fire-resistant gypsum board. Once a fire breaks out, it will keep its structural integrity for a long time, thus blocking the spread of the flame.

Fireproof gypsum board is different from ordinary gypsum board in formula, and glass fiber is added to increase strength, which can effectively enhance the integrity of the board in case of fire. Ensure that it has a certain strength in case of fire, and prolong the fire resistance time. Strive for precious escape and fire fighting time. Reducing the keel spacing can also greatly improve the strength and stability of the partition wall and help to resist fire.

In addition, modern families are very particular about the choice of security doors. There are many kinds of security doors on the market, but if you want to consider fire safety, mesh should be the best choice. Because it is convenient for firefighters to carry out demolition after indoor fire, it can speed up the rescue and fire fighting actions of firefighters, thus minimizing casualties and fire losses.
