(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) 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).
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.
