万里对钢结构工程的耐火设计

时间:2023-04-20 14:59:36

有机防火堵料今后,随着以上两者在高层建筑中的具体应用,则对钢结构工程的耐火设计甚为有利。
In the future, with the concrete application of the above two materials in high-rise buildings, it will be very beneficial to the fire resistance design of steel structural engineering.
其次,应使隔墙、吊顶、门窗、隔断等构件具有良好的耐火性能。这些部位多涉及内部装修,故其不燃、难燃化乃是防火设计的重点之。为充分说明问题,这里需对火灾荷载先行阐述之“所谓火灾荷载,即单位地板面积上的等价可燃物,通常以公斤7米2表示。它是以木材的发热萤为菡准而计舞确定的,当室内有多种可燃物时,应据其单位发热没分别换箅为等价的木材重量。
Secondly, components such as partitions, suspended ceilings, doors and windows, and partitions should have good fire resistance. These parts often involve internal decoration, so their non combustible and non combustible properties are the key points of fire prevention design. To fully illustrate the issue, it is necessary to first elaborate on the fire load. The so-called fire load refers to the equivalent combustible material per unit floor area, usually expressed in kilograms of 7 square meters. It is determined based on the calorific value of wood. When there are multiple combustible materials in the room, the equivalent weight of wood should be calculated based on their unit calorific value.
