彩钢板、金属夹芯板材的应用

发布时间:2021-12-30 来源:/

一、非上人屋面的屋面板(比如拱形屋面板),可以采用单面彩钢板。
1、 The roof panel of non accessible roof (such as arched roof panel) can adopt single-sided color steel plate.
二、采用可燃材料(聚苯乙烯、聚氨酯等)作为芯材的金属夹芯板材,火灾时易蔓延且难以扑救,产生大量有毒烟气,应以严格控制。
2、 The metal sandwich plate with combustible materials (polystyrene, polyurethane, etc.) as the core material is easy to spread and difficult to put out in case of fire, resulting in a large amount of toxic smoke, which should be strictly controlled.
三、采用不燃材料(A级)作为芯材的金属夹芯板材,可以应用在建筑中的非承重外墙、房间隔墙和屋面板等部位,但应满足《建规》规定的对应耐火极限要求(3.2.1、5.1.2)。具体说明如下:
3、 The metal sandwich plate with incombustible material (Class A) as the core material can be applied to the non load-bearing exterior wall, room partition wall, roof slab and other parts of the building, but shall meet the corresponding fire resistance limit requirements (3.2.1, 5.1.2) specified in the building code. The specific instructions are as follows:
1、建筑中的防火墙、承重墙、楼梯间的墙、疏散走道隔墙、电梯井的墙以及楼板等构件,不能采用金属夹芯板材。
1. The firewall, load-bearing wall, staircase wall, evacuation aisle partition wall, elevator shaft wall, floor and other components in the building shall not use metal sandwich plate.

这些部位要求具有较高的燃烧性能和耐火极限,不燃金属夹芯板材的耐火极限受其夹芯材料的容重、填塞的密实度、金属板的厚度及其构造等影响,不同生产商的金属夹芯板材的耐火极限差异较大且通常均较低,难以满足相应建筑构件的耐火性能、结构承载力及其自身稳定性能的要求,因此不能采用金属夹芯板材。
These parts are required to have high combustion performance and fire resistance limit. The fire resistance limit of incombustible metal sandwich panels is affected by the volume weight of the sandwich material, the compactness of the packing, the thickness and structure of the metal plate, etc. the fire resistance limits of metal sandwich panels from different manufacturers vary greatly and are usually low, which is difficult to meet the fire resistance of corresponding building components The requirements of structural bearing capacity and its own stability performance, so metal sandwich plate can not be used.
2、耐火等级为一、二级的建筑,其非承重外墙、房间隔墙等,不宜采用金属夹芯板材。
2. For buildings with fire resistance rating of grade I and II, metal sandwich plates should not be used for non load-bearing exterior walls and room partitions.
依《建规》要求(3.2.1、5.1.2),这些部位的耐火极限要求较高,分别为不低于0.75h和0.50h,参照上述原因,也不宜采用金属夹芯板材。确需采用时,夹芯材料应为不燃材料(A级),且应确保符合对应构件的耐火极限要求。
According to the requirements of the building code (3.2.1 and 5.1.2), the fire resistance limit of these parts is higher, which is not less than 0.75h and 0.50h respectively. Referring to the above reasons, metal sandwich plate should not be used. When it is necessary to use, the sandwich material should be non combustible material (class a), and it should ensure that it meets the fire resistance limit requirements of corresponding components.
3、耐火等级为三、四级的建筑,其非承重外墙、房间隔墙等,可以采用金属夹芯板材,但应符合《建规》对相应构件的耐火极限要求。
3. For buildings with fire resistance rating of grade III and IV, metal sandwich plates can be used for non load-bearing exterior walls and room partitions, but they shall meet the fire resistance limit requirements of corresponding components in the building code.
4、非上人屋面的屋面板,可以采用金属夹芯板材。
4. For the roof slab of non accessible roof, metal sandwich plate can be used.
5、对于上人屋面的屋面板,由于夹芯板材受其自身构造和承载力的限制,无法达到《建规》相应耐火极限要求,此类屋面不能采用金属夹芯板材。
5. For the roof slab of accessible roof, because the sandwich plate is limited by its own structure and bearing capacity, it cannot meet the corresponding fire resistance limit requirements of the building code, and metal sandwich plate cannot be used for this kind of roof.
