近年来,从安全防范角度出发,我国南方地区的住宅分户门已逐步采用实腹钢门,且门扇为全钢板,钢板厚1.2mm左右。钢门的优点是门的强度与木门相比大大提高。但钢门除费用较高外,尚有如下缺点:(1)门扇启闭时,金属摩擦碰撞的噪声很大,隔音性能不如木门;(2)按有关设计和规定制作的钢门,其门扇的刚度没有木门好;(3)隔热、保温性能较差。为克服或减小实腹钢制住宅分户门的上述缺点,结合钢门的结构情况,提出如下改进建议,即:在钢门内侧增做木筋,再钉上纤维板或其他材料。具体做法是:
In recent years, from the point of view of safety precautions, the residential door in the southern part of China has gradually adopted the solid steel door, and the door leaf is made of steel plate, and the steel plate is about 1.2mm thick. The advantage of steel doors is that the strength of the doors is greatly improved compared to wooden doors. However, in addition to the high cost of steel doors, there are also the following shortcomings: (1) When the doors are opened and closed, the metal friction collision noise is very loud, and the sound insulation performance is not as good as wooden doors; (2) Steel doors made according to the relevant design and regulations, their doors The stiffness is not as good as the wooden door; (3) The insulation and heat insulation performance are poor. In order to overcome or reduce the above-mentioned shortcomings of the split door of the solid steel house, combined with the structural condition of the steel door, the following improvement proposal is proposed: the wood ribs are added inside the steel door, and then the fiberboard or other material is nailed. The specific approach is:
