    &nbsp;而我们根据修建木材的耐火等级，作出提高木构件的耐火极限办法。说了半天木构件的耐火极限，必定会想什么是耐火极限？它是指某个构件在专业火炉中依照模仿火灾温度进行焚烧，从开端到失掉一切功用的时间。例如厚度5厘米的方木胶合木门放进专业火炉中焚烧，可以焚烧一个小时，也就阐明厚度5厘米方木胶合木门的耐力极限为1小时。并且木构件截面的不同，其耐火极限也不同，木构件的截面越大耐火极限也就越高。
</p>
<p class="p" style="margin-left:0.0000pt;text-indent:15.2500pt;padding:0pt 0pt 0pt 0pt;">
    &nbsp;木材在焚烧进程中表面有层木炭，它有极好的隔热作用因此减小了木材的热分解。对于提高<a class="attach inline_attach" href="http://www.laiyear.com/projects/%E4%B8%9C%E9%98%B3%E5%87%A4%E5%87%B0%E8%B0%B7%E5%A4%A9%E6%BE%9C%E9%85%92%E5%BA%97%E6%9C%A8%E7%BB%93%E6%9E%84%E5%BA%A6%E5%81%87%E5%88%AB%E5%A2%85.html" target="_blank">木屋别墅</a>的耐火极限途径有两种，一个是加抹石灰层或石膏板，石灰是一种气硬性资料，也就是说，它的硬化是与空气中的二氧化碳发作反应构成较为巩固的碳酸钙。所以可以促进石灰抹面的硬化，起到防火成效。
