Curtain wall aluminum plate reinforcement spacing between the number of appropriate, the country has no standard?
As to the stiffener of the aluminum veneer, what are the following points?:1, aluminum reinforcement spacing is generally around 600mm, in order to ensure the aluminum plate in the positive and negative pressure conditions within the scope of deformation. When aluminum plate is welded, there is internal stress due to welding deformation (this internal stress can not be completely eliminated for a long time), and the rigidity of reinforcing bar should also be increased.2. The sectional dimension and spacing of stiffeners shall be determined according to the calculated wind pressure of the aluminum plate. But it is worth noting that the reinforcement calculation of single aluminum plate strengthening is different from the glass curtain wall, first, its strength is certainly no problem (still not seen the wind blowing broken plate, there is no joke) deflection possibility, bend off and windy weather also very few people to pay attention to the single aluminum plate plate surface after deformation the scenery. Therefore, the calculation of deflection of stiffeners are considered under the condition of wind strength and deflection when the winds of aluminum can cause permanent plastic deformation.In fact, aluminum veneer manufacturers generally use the single aluminum plate edge folding groove made of aluminum and 20*40*20, installed in the distance about 600mm. Also useful for profile (grooved aluminum) stiffenersThe spacing between stiffeners is very important to the cost of production. Generally speaking, the spacing of stiffeners will be changed from 600 to 350, and the cost will be increased by 8~15 yuan / square meter
