防火铝塑复合板的两种折边形式

1.铝塑复合板折边

铝塑复合板开槽一般可开V 型槽、U 型槽等,几种典型的开槽方式 如图1 所示。铝塑复合板的板材在裁板时要考虑到折边加放的尺寸, 一般每边加放25mm 左右。
APCP can be slotted, slotted U groove type V, several typical slotting method as shown in figure 1. APCP in sheet cutting board should consider when folding add size, generally each side add about 25mm.
裁好的复合板需要四边刨槽,即切去一 定宽度的内层铝板和塑料层,开槽深度必须严格控制在正面铝板后至 少保留0.3mm 厚的塑料芯材,以保证铝塑复合板有足够的韧性, 防 止折边处铝皮断裂,然后折边成90°阳角,这样板面自重和幕墙随 时都会受到的正负风荷载压力均由四个边0.5mm 铝板承受,因此, 开槽折边处是铝塑复合板面板的最薄弱环节,也是风荷载作用下最先破坏的部位。
Cut the composite board requires four gouging, trim a fixed width of the inner layer of the aluminum and plastic layer, the groove depth must be strictly controlled in front aluminum plate to retain less 0.3mm thick plastic core material, in order to guarantee the aluminum-plastic composite board has enough toughness, folding aluminum sheet fracture prevention, then fold into 90 DEG yang angle, with such surface gravity and curtain wall will be positive and negative wind pressure were from four sides of 0.5mm aluminum under, therefore, slotted flap is the weakest part of the aluminum plastic composite panel, is wind load under the action of the first failure of the site.

2.铝塑复合板折边加固

铝塑复合板一般通过四周折边增大板的刚度,而且可以避免铝塑复 合板的芯材在大气中外露。铝塑复合板的折边可按需要设置加强边框, 铝塑复合板幕墙面板不宜使用铝角码作为边框,应使用铝型材作为加 强边框。加强边框可采用金属方管、槽形和角形等,其应与面板可靠连结,并应有防腐措施。
APCP generally through the folding sides around the increase in stiffness, but also can avoid of aluminum plastic composite plate core material in atmospheric exposure. The hem of aluminum-plastic composite board can according to need is provided with a reinforcing frame, aluminum-plastic composite panel curtain wall panel should not use aluminum bracket as a border, using aluminum as frame. The reinforced frame can be made of metal tube and groove and angle, and the panel reliable link, and should have anti-corrosion measures.
边框与铝塑复合板的折边的连接可使用铝铆 钉,其连接应满足传力要求可靠连结。在实际工程中,铝塑复合板的 折边处的处理形式分为以下两种:
The connecting frame and aluminum-plastic composite board folding can use aluminum rivet, the connection should meet the requirements of reliable transmission link. In practical engineering, processing form the hem aluminum-plastic composite board is divided into the following two:
①可按需要设置加强边框;
Can be set by the need to strengthen the border;
②没有 设置加强边框
Did not set to strengthen the border
