楼承板现如今的使用率还是比较高的，当然它的性能优势也是有目共睹的好，但是如果不注意的话就会让该板材的使用寿命大大缩短，那么楼承板的寿命什么情况下会出现缩短？

　　The utilization rate of the floor plate is still relatively high, of course, its performance advantage is also obvious, but if you do not pay attention to it will make the service life of the plate greatly shortened, then the life of the floor plate under what circumstances will be shortened?

　　重使用由荷载变化，超期服役，规范和规程改变导致结构承载力不足；由于化学物质的侵蚀而产生腐蚀以及电化学腐蚀致使楼承板构件截面削弱；温差作用下引起构件或连接变形、开裂和翘曲；构件由于各种意外产生变形、扭曲、伤残、凹陷等，致使构件截面削弱，杆件翘曲，连接开裂等；其它包括设计、生产、施工中的失误及服役期中的违规使用和操作等。

　　In heavy use, the structural bearing capacity is insufficient due to load variation, extended service, and changes in codes and procedures. Corrosion due to chemical erosion and electrochemical corrosion resulting in the section of the floor bearing plate members weakened; Temperature difference causes deformation, cracking and warping of components or connections; Component due to various accidental deformation, distortion, disability, depression, etc., resulting in the weakening of the component section, rod warping, connection cracking, etc.; Others include mistakes in design, production and construction and illegal use and operation during the service period.

　　另外，济南楼承板原材料的利用率涉及学问题有关，原材料的展开宽度是多少，辊压成型后的有效宽度是多少，有效宽度除以原材料的供给宽度，乘以百分比，楼板的利用率，利用率越高，价格越便宜。

　　In addition, ji 'nan floor plate utilization rate of raw materials related to learning problems, how much is the width of raw materials, roll forming effective width is how much, effective width divided by the supply width of raw materials, multiplied by percentage, floor utilization rate, the higher the utilization rate, the cheaper the price.

　　市场上的大楼承板、压型钢板的规格型号种类非常多，其中一部分楼承板采用市场上常用的镀锌板材宽度，这是市场上常用的规格，成本比较便宜，因此，可以看出原料的宽度决定了楼承板的利用率，所以购买时要选择可靠的厂家购买产品。

　　The building plate on the market, because there are so many kinds of specifications steel sheet part LouCheng plate with common galvanized plate width on the market, which is commonly used specifications, the market cost is cheaper, so it can be seen that the width of raw material determines the utilization of LouCheng board, so should choose when buying a reliable manufacturer to buy the product.

　　楼承板的寿命什么情况下会出现缩短？以上讲解了几个原因，此外我们还延伸了下话题，如果各位想更好的使用楼承板，就需要去多认识它。更多内容就来网站www.jnhxtcg.com咨询吧！

　　Under what circumstances will the life of the floor bearing plate be shortened? The above explains several reasons, in addition, we also extend the topic, if you want to better use the floor bearing plate, you need to know more about it. More content to the website www.jnhxtcg.com consultation!
