济南彩钢板房作为现代社会一种灵活、简单、便捷的新型活动房,其优点和便利性是非常明显的。这种简易房屋的房体主要承重框架是钢结构,墙体四周采用夹层彩钢板作为墙体,这样的简易房屋具有建造快而简单,拆除方便,而且还能结合使用和再利用,非常环保。
  Jinan color steel plate house is a new flexible, simple and convenient activity house in modern society, its advantages and convenience are very obvious. The main load-bearing frame of the simple house is steel structure. The walls are surrounded by sandwich color steel plates. Such a simple house has the advantages of fast and simple construction, convenient demolition, combined use and reuse, and is very environmentally friendly.

  钢结构是彩钢房屋的主体框架,所以钢结构的稳定性直接决定了移动房屋的稳定性,一旦钢结构变形就会变得非常不安全。为了避免钢结构的变形,人们常用以下四种方法:

  Steel structure is the main frame of color steel house, so the stability of steel structure directly determines the stability of mobile house. Once the steel structure is deformed, it will become very unsafe. In order to avoid the deformation of steel structure, people often use the following four methods:
  1、夹具固定方法:用非常刚性的夹具夹住焊接件,用力控制变形,然后焊接,这种方法称为夹具固定方法。
  1. Fixture fixing method: clamp the weldment with a very rigid fixture, control the deformation with force, and then weld. This method is called fixture fixing method.
  在焊接过程中,焊接件内部的膨胀力和收缩力受夹紧力的限制,可以明显降低变形。但是,这种方法不适用于需要较少内应力的构件,因为焊接部分内应力较大。
  In the welding process, the expansion force and contraction force inside the weldment are limited by the clamping force, which can significantly reduce the deformation. However, this method is not suitable for members requiring less internal stress, because the internal stress in the welding part is large.
  2、反向变形法:焊接前应根据焊接金属构件来判断构件。当焊接冷却时,会出现变形方向和收缩量,焊接部位会提前向相反方向弯曲或倾斜。焊接后,由于自身的收缩和变形,它会回到预定的形状位置。防止焊接变形,降低焊接应力。
  2. Reverse deformation method: before welding, the components shall be judged according to the welded metal components. When the welding is cooled, there will be deformation direction and shrinkage, and the welding part will bend or incline to the opposite direction in advance. After welding, due to its shrinkage and deformation, it will return to the predetermined shape position. Prevent welding deformation and reduce welding stress.
  3、采用定位控制方法:在构件焊接前,用许多焊点对焊接部位或周围的焊点进行定位,同时也在焊缝的两侧施加重量,这种方法称为定位控制方法。
  3. Adopt the positioning control method: before the component welding, use many welding points to position the welding parts or the surrounding welding points, at the same time, apply weight on both sides of the weld, this method is called positioning control method.
  4、焊接顺序法:正确安排焊接顺序是防止焊接变形的有效方法。焊接变形的规律是:焊缝引起的变形较大,各焊缝引起的变形一般不能相互抵消,产生的变形方向与焊缝引起的变形方向一致。
  4. Welding sequence method: correct arrangement of welding sequence is an effective method to prevent welding deformation. The rule of welding deformation is: the deformation caused by the first weld is large, and the deformation caused by each weld can not offset each other generally, and the deformation direction generated is the same as that caused by the first weld.
