压瓦机组装在焊接应力作用下，如果焊件的拘束度较小，如板厚较薄或处于安闲无拘束状态下，则焊件会发作相应的标准改动或缩短或弯曲或翘曲等。如果焊件的拘束度很大，如板厚较大、形状凌乱或因人为施加的夹具而处于较强的拘束状态下，此刻焊件不能安闲变形，但在焊接应力作用下会发作有些的应变，一起发作较大的剩余应力。焊缝区剩余应力的峰值可以到达资料的屈服强度值。

　　因此焊接内应力们的大小与钢材的热膨胀系数以及接头拘束度有关。规划钢材的膨胀系数改动很小，而拘束度则与规划节点方法、施焊次序、板厚、外加夹具的紧固程度等各种要素有关。彩钢设备的基础要分红两个或多个有些，以便于加工，搬运（起吊），运送。如果估量要扩展，或往后要固定其他组件**要将基础分段，基础的联接端要设备附加板和联接件，压瓦机较长压瓦机的基础要分红两个或多个有些，以便于加工，搬运（起吊），运送。如果估量要扩展，或往后要固定其他组件**要将基础分段，基础的联接端要设备附加板和联接件，压瓦机基础一定要能完结冷弯成型顶用润液的再循环，基础分别时，重视每个基础要有再循环润滑，或基础间不漏水联接
