如何避免济南彩钢板房的变形?

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。
As a flexible, simple and convenient new activity room in modern society, Jinan color steel plate house has obvious advantages and convenience. The main load-bearing frame of this simple house is steel structure, and the sandwich color steel plate is used as the wall around the wall. This 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 components requiring less internal stress, because the internal stress of welded parts is larger.
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: the component should be judged according to the welded metal component before welding. When the welding is cooled, there will be deformation direction and shrinkage, and the welding part will bend or tilt to the opposite direction in advance. After welding, due to its own shrinkage and deformation, it will return to the predetermined shape and 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. Using positioning control method: before component welding, many welding points are used to position the welding position or surrounding welding points, and weight is also applied 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: the correct arrangement of welding sequence is an effective method to prevent welding deformation. The rule of welding deformation is: the deformation caused by weld is large, the deformation caused by each weld can not offset each other, and the deformation direction is consistent with that caused by weld.
