FONT-WEIGHT: bold“>施工:</span><span style=“FONT-SIZE: 10.5pt“><br /></span><span style=“FONT-SIZE: 10.5pt“>铝单板和龙骨连接主要有两种形式:角铝连接和副框连接(铝塑板连接方式也一样)。角铝连接是指将角铝直接和铝板的折边用铆钉固定后将角铝固定在龙骨上;副框连接是指将副框和铝板连接后再将副框和龙骨连接。铝单板由于其本身特有的性质决定了它只能在工厂的车间进行加工,工地现场如果发现有个别加工有偏差的铝板,在不影响美观和安全的前提下,可以自行对其进行调整,达到所需的要求。但是一旦发现批量性的错板,能进行调整的方法就是将其重新送回车间加工,有可能造成工地工期拖延、工人窝工的情况。</span><span style=“FONT-SIZE: 10.5pt“><br /></span><span style=“FONT-SIZE: 10.5pt; FONT-WEIGHT: bold“>铝板加强</span><span style=“FONT-SIZE: 10.5pt“>:</span><span style=“FONT-SIZE: 10.5pt“><br /></span><span style=“FONT-SIZE: 10.5pt“>由于有些业主或设计师想要在工程完工后,得到一些特别的立面效果,导致分格尺寸非常大,在通过计算,发现纯粹的靠铝板不能满足各方面的性能要求,所以就需要对铝板加加强肋。加强肋的种类有三种:钢制<span style=“FONT-FAMILY: Times New Roman“>“U”</span><span style=“FONT-FAMILY: 宋体“>形槽、</span><span style=“FONT-FAMILY: Times New Roman“>“U”</span><span style=“FONT-FAMILY: 宋体“>形槽铝、铝制</span><span style=“FONT-FAMILY: Times New Roman“>“U”</span><span style=“FONT-FAMILY: 宋体“>形槽。由于各种铝板之间不同的成分导致了加强肋和不同的铝板有不同的连接方式:和铝单板连接时可以用焊接的方式将两者连接(图</span><span style=“FONT-FAMILY: Times New Roman“>3</span><span style=“FONT-FAMILY: 宋体“>);和铝塑板就不能,只能用结构胶或结构胶、双面胶条配合的方式连接(图</span><span style=“FONT-FAMILY: Times New Roman“>4</span><span style=“FONT-FAMILY: 宋体“>);和蜂窝板连接可有两种方法:铆钉铆接和粘结。</span></span><span style=“FONT-SIZE: 10.5pt“><br /></span><span style=“FONT-SIZE: 10.5pt; FONT-WEIGHT: bold“>残值:</span><span style=“FONT-SIZE: 10.5pt“><br /></span><span style=“FONT-SIZE: 10.5pt“>所谓残值就是加工时产生的边角料。以上列举的三种铝板在其生产过程中必然的会产生或多或少的废料,由于铝单板和蜂窝板昂贵的原材料价格,所以造成的生产成本比起铝塑板来说是要大的多,从而成品的价格就比铝塑板高的多。</span></p>
