What fire protection problems should be paid attention to during the use of sandwich panels

Color steel composite board is a product that we often see in our lives. It has been widely used in our lives. It has the advantages of convenient use and beautiful appearance, so it is used by most users and saves costs for the construction industry. , Improve production efficiency. Because the outer layer has a layer of color-coated iron, but the core material uses flammable materials such as polystyrene and polyurethane foam. Once the temperature exceeds 600 degrees, after the fire is burned, the outer iron sheet will be burned softly, and the inner layer will be made of combustible materials such as foam. The fire is easy to spread, and the combustion products are highly toxic, which can easily cause major property losses and casualties. So let's take a look at the fire protection issues that should be paid attention to during the use of color steel composite panels.

Sandwich panel

1. Asbestos boards and fire-resistant wool should be used as fillers as much as possible, and the fire-fighting conditions on site can only be met when the fire resistance limit is reached.

2. During use, some heat sources and fire sources should not be close to the color steel composite board, and should keep a certain distance. If the kitchen is installed in the room, there should be an insulation layer, and the wall surface should be provided with a fireproof rock wool insulation layer.

3. The wires and cables must not cross the color steel composite board. If you need to pass through, you should add a protective cover. The sockets and switch boxes are galvanized metal boxes, and they are surface mounted. Equipped with indoor and outdoor fire fighting equipment. When necessary, a fire alarm should be installed to facilitate the rapid evacuation of personnel.

4. The distance between the color steel composite panels is at least 6 meters. Iron fences, billboards and other obstacles that affect escape, fire fighting and rescue shall not be set up against the regulations.

5. Nurseries, kindergartens, nursing homes, welfare homes, boarding schools, medical institutions and other densely populated places shall not be used below the standard; densely populated places below the requirements shall not pass the fire protection design review, acceptance or record and random inspection.

6. If the public gathering place used for construction is lower than the requirements, it shall not pass the use and pre-business fire inspection; for the crowded places built with colored steel composite panels, if it is lower than the requirements, it shall be temporarily blocked and stopped. Use changes. If it cannot be changed, it should be removed.

The above is the entire content of the precautions for fire prevention use of color steel composite panels introduced by the editor.
