①使用年限在十年内时宜采用铝塑板,原因是现在的铝塑板良莠不齐,鱼目混珠,加之考虑施工时需现场加工,内外表面的铝箔只有0.5mm许多厂家的铝塑板是采用辊涂工艺进行表面处理的,表面有一定的纹理,因此设计人员在进行材料使用率优化时要注意不可将板面横竖乱放,影响效果按照规范要求,铝塑板的边部需加强,可采用铝方管或角铝等固定,粘接胶宜采用中性硅酮结构胶当铝塑板安装部位在建筑物的防火区间或靠近该区时,应采用防火型铝塑板当铝塑板设计尺寸较大时,需进行加强肋的结构计算以确定肋的规格和分布间距固定铝塑板和龙骨的耳板多采用角铝,角铝的长度不宜小于50mm,角铝在龙骨一边上宜开长孔,保证板面的热胀冷缩。设计人员还需注意不要在易破坏部位使用铝塑板,否则需在背面做加固处理。
(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时宜采用铝单板。铝单板强度好,耐腐蚀性强,在工厂加工能保证质量。由于施工现场所要铝单板是在工厂加工成成品,直接安装即可,所以设计人员在做铝单板加工图时需注明铝单板的材质、厚度、固定耳板规格和加工尺寸及分布间距、加工误差要求、加强肋的规格和分布间距等。需要注意的是耳板靠近龙骨一侧的固定孔的加工尺寸要考虑热胀冷缩,一般在耳板上开长圆孔,固定螺钉时要尽量将螺钉固定在长圆孔的中部,这样即方便安装又可有伸缩性,同时要注意板四周的耳板要错位固定,否则在安装时可能“打架”铝单板表面宜采用氟碳喷涂(氟碳树脂的各项性能都较其他处理方式优越),尽量避免采用辊涂方式(有的加工厂的辊涂产品有方向性,影响外观效果)。
(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).
现在有很多建筑采用穿孔铝单板以丰富效果,如果穿孔铝单板后面没有防水隔离层,那就可在实体墙外表面做防水层或作双层幕墙或直接在穿孔铝单板背面做防水隔离层,然后再设计穿孔铝单板。铝单板的孔洞尺寸必须大于板厚(工艺要求),孔间距及尺寸要依据材质的强度要求(纯铝单板较合金铝单板强度低),同时考虑加强肋的安装,避免影响外视效果。合理的设计是先做样板,通过远观和近看确定孔尺寸及间距。
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.
