Reasonable design of fire protection structure of insulation system

Release time:2018-09-25 11:38:30

According to the current technical conditions, under the premise of satisfying the requirements of the relevant standards for thermal insulation materials, it is not necessary and cannot make excessive demands on the flame retardancy policy of organic thermal insulation materials, but should pay more attention to the overall fire safety function of the system. As long as the structural method of the external thermal insulation system is reasonable, the overall system response to fire is excellent, and the fire safety function of the external thermal insulation system can be ensured. Nowadays, the fire protection function of the external wall insulation structure can be enhanced by means of structural fire protection maintenance surface layer, fire prevention distance and cavityless structure. Although the insulation layer of the external thermal insulation of the external wall is outside the outer wall, the fire prevention treatment cannot be ignored. The outer surface of the insulation layer around the entrance and exit of all the doors and windows of the building must be completely covered with fireproof materials, and there must be no exposed parts. The anti-insulation material is lit by the flames drawn from the window.
 
When the building exceeds a certain height, special fireproof structure treatment is required. Generally, fire barrier strips composed of rock wool slats should be installed every 2 to 3 floors. Experiments have shown that fire distance has a significant effect on the suppression of fire extension. The cavityless structure not only advances the stability of the external insulation structure, but also reduces the risk of fire. The cavity structure itself has an air layer that is integrally connected, and the fire is very simple, causing the rapid extension of the fire.
