民用建筑工程中,木门框还在大量使用。木门框安装后容易变形,整修很困难,会出现门框宽窄不一,门扇会失去方正形状,影响美观。竣工后再出现门框变形,修复更困难,变形严重的只好拆下重做。这里介绍一种用螺栓修复变形门框的方法,既方便效果又好。方法是在靠门框的墙上120毫米处钻一圆孔,放入一截开口钢管,用螺栓套上,将门框拉紧,使变形门框复原。见图1。一、零件制作
In civil construction projects, wooden door frames are still in heavy use. After the wooden door frame is installed, it is easy to be deformed, and it is difficult to refurbish. There will be different widths and widths of the door frame, and the door leaf will lose the square shape and affect the appearance. After the completion of the deformation of the doorframe, it was more difficult to repair it, and if it was seriously deformed, it had to be removed and redone. Here is a method for repairing a deformed doorframe with bolts, which is both convenient and effective. The method is to drill a round hole 120 mm on the wall of the door frame, place a piece of open steel pipe, put it on the bolt, and tighten the door frame to restore the deformed door frame. see picture 1.
