濟南彩鋼板房作為現(xiàn)代社會一種靈活、簡單、便捷的新型活動房，其優(yōu)點和便利性是非常明顯的。這種簡易房屋的房體主要承重框架是鋼結構，墻體四周采用夾層彩鋼板作為墻體，這樣的簡易房屋具有建造快而簡單，拆除方便，而且還能結合使用和再利用，非常。
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.
鋼結構是彩鋼房屋的主體框架，所以鋼結構的穩(wěn)定性直接決定了移動房屋的穩(wěn)定性，一旦鋼結構變形就會變得非常不。為了避免鋼結構的變形，人們常用以下四種方法:
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、夾具固定方法:用非常剛性的夾具夾住焊接件，用力控制變形，然后焊接，這種方法稱為夾具固定方法。
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.
在焊接過程中，焊接件內部的膨脹力和收縮力受夾緊力的限制，可以明顯降低變形。但是，這種方法不適用于需要較少內應力的構件，因為焊接部分內應力較大。
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、反向變形法:焊接前應根據(jù)焊接金屬構件來判斷構件。當焊接冷卻時，會出現(xiàn)變形方向和收縮量，焊接部位會提前向相反方向彎曲或傾斜。焊接后，由于自身的收縮和變形，它會回到預定的形狀位置。防止焊接變形，降低焊接應力。
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:在構件焊接前，用許多焊點對焊接部位或周圍的焊點進行定位，同時也在焊縫的兩側施加重量，這種方法稱為定位控制方法。
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、焊接順序法:正確安排焊接順序是防止焊接變形的有效方法。焊接變形的規(guī)律是:焊縫引起的變形較大，各焊縫引起的變形一般不能相互抵消，產生的變形方向與焊縫引起的變形方向一致。
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.
