        鋁板幕墻材料制作的技巧及標準

        ①使用年限在十年內時宜采用鋁塑板,原因是現在的鋁塑板良莠不齊,魚目混珠,加之考慮施工時需現場加工,內外表面的鋁箔只有0.5mm許多廠家的鋁塑板是采用輥涂工藝進行表面處理的,表面有一定的紋理,因此設計人員在進行材料使用率優化時要注意不可將板面橫豎亂放,影響效果按照規范要求,鋁塑板的邊部需加強,可采用鋁方管或角鋁等固定,粘接膠宜采用中性硅酮結構膠當鋁塑板安裝部位在建筑物的防火區間或靠近該區時,應采用防火型鋁塑板當鋁塑板設計尺寸較大時,需進行加強肋的結構計算以確定肋的規格和分布間距固定鋁塑板和龍骨的耳板多采用角鋁,角鋁的長度不宜小于50mm,角鋁在龍骨一邊上宜開長孔,保證板面的熱脹冷縮。設計人員還需注意不要在易破壞部位使用鋁塑板,否則需在背面做加固處理。
        (1) the use of aluminum plastic plate in ten years, the reason is that the present aluminum and plastic plates are good and bad, mixed with fish and eyes, and the construction needs to be processed in the field. The aluminum foil on the inside and outside surface is only 0.5mm many manufacturers of aluminum plastic plate surface treatment with roll coating process, with a certain texture on the surface, so the designers are in the process. When the utilization ratio of the material is optimized, the surface of the plate should not be placed vertically, the effect of the effect on the edge of the aluminum plastic plate should be strengthened in accordance with the requirements of the standard, the aluminum square tube or the angle aluminum can be fixed, and the adhesive is suitable for the use of neutral silicone structural adhesive when the installation part of the aluminum plastic plate is in the fire zone of the building or near the area. When the design size of aluminum plastic plate is large, it is necessary to calculate the structure of the ribs to determine the size and distribution distance of the ribs to fix the aluminum plate and the ear plate of the keel. The length of the angle aluminum should not be less than 50mm, and the angular aluminum should open the long hole on the side of the keel so as to ensure the heat expansion and contraction of the plate. Designers also need to be careful not to use aluminum plastic panels at vulnerable locations, otherwise they need to be reinforced on the back.
        ②使用年限在十年以上時宜采用鋁單板。鋁單板強度好,耐腐蝕性強,在工廠加工能保證質量。由于施工現場所要鋁單板是在工廠加工成成品,直接安裝即可,所以設計人員在做鋁單板加工圖時需注明鋁單板的材質、厚度、固定耳板規格和加工尺寸及分布間距、加工誤差要求、加強肋的規格和分布間距等。需要注意的是耳板靠近龍骨一側的固定孔的加工尺寸要考慮熱脹冷縮,一般在耳板上開長圓孔,固定螺釘時要盡量將螺釘固定在長圓孔的中部,這樣即方便安裝又可有伸縮性,同時要注意板四周的耳板要錯位固定,否則在安裝時可能“打架”鋁單板表面宜采用氟碳噴涂(氟碳樹脂的各項性能都較其他處理方式優越),盡量避免采用輥涂方式(有的加工廠的輥涂產品有方向性,影響外觀效果)。

        (2) aluminum single board should be used for more than ten years. Aluminum veneer has good strength and strong corrosion resistance. It can ensure quality in factory processing. As the aluminum sheet of the construction site is processed into finished product in the factory, it can be directly installed, so the designer should indicate the material, thickness, fixed ear plate specification and machining dimensions and distribution spacing, processing error requirements, strengthening rib gauge and distribution spacing when making aluminum sheet processing drawings. It is important to note that the machining dimension of the fixed hole near the side of the keel should consider the heat expansion and contraction, the long circular hole is generally opened on the ear plate, and the screw should be fixed to the middle of the long circular hole as far as possible, so that it is convenient to install and can be retracted, at the same time, it should be noted that the ear plate around the plate should be staggered and fixed, otherwise the installation should be installed. It is possible to use fluorocarbon spray on the surface of the "fight" aluminum sheet (the performance of fluorocarbon resin is superior to other treatment methods), and the way of roll coating is avoided as far as possible (the roll coating of some processing plants is directional and affects the appearance effect).
        現在有很多建筑采用穿孔鋁單板以豐富效果,如果穿孔鋁單板后面沒有防水隔離層,那就可在實體墻外表面做防水層或作雙層幕墻或直接在穿孔鋁單板背面做防水隔離層,然后再設計穿孔鋁單板。鋁單板的孔洞尺寸必須大于板厚(工藝要求),孔間距及尺寸要依據材質的強度要求(純鋁單板較合金鋁單板強度低),同時考慮加強肋的安裝,避免影響外視效果。合理的設計是先做樣板,通過遠觀和近看確定孔尺寸及間距。
        Many buildings now use perforated aluminum sheet to enrich the effect. If there is no waterproof isolation layer behind the perforated aluminum sheet, the waterproof layer or double curtain wall can be made on the outer surface of the solid wall or the waterproof isolation layer directly on the back of the perforated aluminum sheet, and then the perforated aluminum sheet can be redesigned. The pore size of the aluminum sheet must be larger than the thickness of the plate (process requirements). The distance and size of the hole should be based on the strength requirements of the material (the strength of the pure aluminum sheet is lower than that of the alloyed aluminum sheet). At the same time, the installation of the ribs should be strengthened to avoid the effect of the external sight. The reasonable design is to make the template first, and to determine the size and spacing of the hole through far and near view.
