济南彩钢板房的防火四大措施

这些年，一些兴旺城市呈现了很多大型的钢构造修建，摩天大楼，钢构造桥梁，钢材受到了修建业的不断添加的青睐。In recent years, a number of large steel buildings, skyscrapers and steel bridges have been built in some prosperous cities, and steel has been continuously favored by the construction industry.
钢材具有抗震、抗弯、不行燃烧等特性。在实际修建使用中，钢材既能够相对添加修建物的荷载才能，也能够满足修建规划外型多样的要求，还避免了传统房子混凝土修建资料不能拉伸，曲折的的缺乏。
Steel has the characteristics of earthquake resistance, bending resistance and no burning. In the actual construction and use, steel can not only increase the load capacity of building materials, but also meet the various requirements of building planning, but also avoid the traditional house concrete construction materials can not stretch, tortuous lack.

However, due to its own characteristics, there are some defects that can not be avoided in the fire protection, and the mechanical properties, such as heat resistance yield point, tensile strength and elastic modulus, will decrease sharply due to the addition of temperature.
济南彩钢板房通常在温度到达450摄氏度～650摄氏度的温度中就会失掉承载才能，从而致使形变，钢柱、钢梁会变的曲折，变形的太大，也就不能再持续使用了
Ji'nan color steel board room is usually in the temperature of 450 degrees Celsius to 650 degrees Celsius temperature will lose bearing capacity, resulting in deformation, steel column, steel beam will become tortuous, deformation is too large, it can not continue to use
假如钢构造修建没有加维护办法，它的耐火极限为15分钟摆布。钢构造的耐火时刻长短还与钢构件吸热的速度有关。
If there is no maintenance method for steel structure construction, its fire resistance limit is 15 minutes. The length of fire resistance of steel structure is also related to the speed of heat absorption of steel members.
怎么进步钢构造修建的耐热性呢？
How to improve the heat resistance of steel structure construction?
提高济南彩钢板房的耐热性办法是多种多样的，要根据具体的状况而定。比方说选用耐火、绝热资料隔绝火焰对钢构造直接灼烧，下降热量传递的速度从而推延钢构造温升、强度变弱的时刻等。
The method of improving the heat resistance of Ji'nan color steel plate room is various, depending on the specific situation. For example, fire resistant and adiabatic materials are used to separate flame from direct burning of steel structure, to decrease the speed of heat transfer, and to delay the temperature rise and strength weakening of steel structure.
笔者以为不管采纳何种办法，其原理是一致的。
The author thinks that no matter what method is adopted, the principle is consistent.
济南彩钢板房的防火四大办法
Four methods of fire protection of Ji'nan color steel board room
1：充水水套防火
1: water filled water jacket fire protection
在空心型钢构造内充水有效果。这种办法能使济南彩钢板房在火灾中坚持较低的温度，水吸收资料自身受热的热量，在钢构造内循环。
In hollow steel structure, filling water is the most effective. This method can make the Ji'nan color steel board room adhere to the lower temperature in the fire, the water absorbs the heat of the data itself, and makes the internal circulation in the steel structure.
受热的水经冷却后能够进行再循环或由管道引进凉水来取代受热的水。
After cooling the heated water can be recycled or to replace the heated water by introducing cold water pipe.
2：外包层防火
2: the fire prevention of the outer layer+

顾名思义，即是在钢构造表面添加外包层，能够现浇成型，也能够选用喷涂法。现浇成型的实体混凝土外包层通常用钢丝网或钢筋来加强，以约束缩短裂缝，并确保外壳的强度。
As the name suggests, it is to add the outer layer on the surface of the steel structure, can be cast into shape, also can choose spraying method. The cast in place concrete layer is usually reinforced with steel wire mesh or steel bar to restrain the crack and ensure the strength of the shell.
喷涂法能够在施工现场对钢构造表面涂改砂浆以构成维护层，砂浆能够是石灰水泥或是石膏砂浆，也能够掺入珍珠岩或石棉。同时，外包层也能够用珍珠岩、石棉、石膏或石棉水泥、轻混凝土做成预制板，选用胶粘剂、钉子、螺栓固定在钢构造上。
Spraying method can modify mortar on the surface of steel structure in the construction site to form maintenance layer, mortar can be lime cement or gypsum mortar, also can be mixed with perlite or asbestos. At the same time, the outsourcing layer can be made of perlite, asbestos, gypsum or asbestos cement, light concrete precast plate, using adhesives, nails, bolts fixed on the steel structure.
3：膨胀资料防火
3: expansion data fire prevention
选用钢构造防火涂料维护构件，这种办法具有防火隔热性能好、施工不受钢构造几许形体约束等长处，通常不需要添加辅佐设备，且涂层质量轻，还有必定的漂亮装饰效果，属于现代的防火技术办法。
Selection of fire-resistant coating for steel structure components maintenance, this approach has a good performance, fire insulation construction from steel structure of many physical constraints and other strengths, usually do not need to add auxiliary equipment, and the coating quality of light, there must be the beautiful decorative effect, leading the way to modern fire technology.
4：屏蔽防火
4: shielding fire prevention
钢构造设置在耐火资料构成的墙体或顶棚内，或将构件包藏在两片墙之间的空地里，只需添加少量耐火资料或不添加即能到达防火的意图。这是一种为经济的防火办法。
Steel structure which is arranged on the wall or ceiling refractories, or components concealed in between two pieces of wall space, which can reach the intention not to add fire only by adding a small amount of refractory materials or. This is one of the most economical ways of fire prevention.
目前，济南彩钢板房十分遍及。一旦发作火灾事故，结果十分严峻，会造成很多的人身伤亡，财产损失
At present, Ji'nan color steel plate house is very widespread. Once the fire accident occurs, the result is very serious, it will cause a lot of personal injury and property loss
因而咱们在钢构造的修建挡住，应当加大对钢材的防火维护，以增强其耐火极限。把危害降到低！
Therefore, we should increase the fireproof maintenance of steel in order to strengthen the fireproof limit of the steel structure. Minimize the damage!
