旧房 pre-hung door 安装前,门洞不方正怎么修

旧房翻新装 pre-hung door,最怕门洞不方正。门扇本身没问题,但装完门缝一边大一边小,客户会觉得安装很粗糙。 我安装前会先量 rough opening 的宽、高和两条对角线,再用水平尺看两侧 stud 是否 plumb。偏差小的,用 shim 在 hinge side 先找直,再调整 latch side;偏差大的,不要靠硬拧门框解决,要先修 opening 或补木条。固定螺丝不要一下打死,先挂门试开合,看 reveal 是否均匀,再逐步锁紧。地面不平时,门框底部也要提前切平。旧 trim 要不要保留也要提前说清楚。 经验是,门装得好不好,准备阶段占一半。建议同行别等门框上墙才发现洞口歪,先量对角线和垂直度,照片发给业主确认,必要的修补工时提前说清楚。
