The manufacturer of copper doors will give you an answer on how to measure the width and height of the copper doors when they are installed. 1. Actual measurement of the width and height of the copper doors. If there is no consistency in the measurement of the upper, middle and lower portals, the narrowest point shall be the standard, but the error shall not exceed 20_.

　　2.对于误差超过20mm的要对墙洞进行修正，修正可以用水泥砂浆或石灰进行修正。

　　2. When the error exceeds 20 mm, the wall hole should be corrected. The correction can be made with cement mortar or lime.

　　3.门洞墙体的厚度测量也要量上、中、下三处，看墙体的厚度是否一样，同时也要看左右墙体和门洞顶上墙体的厚度是否一样，不一样的取它们较大值，但误差不得超过5㎜。

　　3. Gate wall thickness measurement should also be measured in the upper, middle and lower three places, to see whether the thickness of the wall is the same, but also to see whether the thickness of the left and right wall and the wall on the top of the door is the same, different take their maximum, but the error should not exceed 5 feet.

　　4.如果墙体厚度的误差超过5㎜，就需要进行修正。

　　4. If the error of wall thickness exceeds 5 inches, it needs to be corrected.

　　5.如果墙壁为丁字墙，就需要用细木工板做宽度为50-60mm的假墙壁安放门套线。厚度同墙壁的墙体厚度一样。

　　5. If the wall is a T-shaped wall, you need to use joinery boards to make a 50-60 mm wide fake wall with door covers. The thickness of the wall is the same as that of the wall.

　　6.门洞墙体的厚度较低不少于80㎜。低与80mm尺寸的门框的强度不是很大，对门的支撑力度不够。如果小于80mm需要将墙体的厚度加厚到80mm以上。

　　6. The thickness of the wall of the portal is at least 80 feet. Low and 80mm size doorframe strength is not very large, the support strength of the door is not enough. If it is less than 80 mm, it is necessary to increase the thickness of the wall to more than 80 mm.

　　7.门洞上面有突出来的横梁时，上面门套线无法安装。也需要用细木工板做50-60mm高的假墙壁，其长度于门洞宽度一样，深度和门洞厚度一致。

　　7. When there is a projecting beam above the door, the upper door sleeve cannot be installed. It is also necessary to use joinery boards to make 50-60 mm high fake walls, the length of which is the same as the width of the door, and the depth is the same as the thickness of the door.

　　8.门洞有台阶的。有台阶一面的脸套线要加上台阶高度，具体尺寸根据台阶的高度来定。

　　8. The doorway has steps. Face covers with one side of the step should be added with the height of the step, and the specific size should be determined according to the height of the step.

　　9.卫生间和厨房门洞墙体的厚度特别要注意的是墙体上贴墙砖的厚度。一般单面贴砖加厚25㎜，两面贴砖加厚50㎜，具体情况由设计师与客户及装修公司三方面签字确认。较终的尺寸要包括墙砖的厚度。较好在墙砖贴好后测量。

　　9. The wall thickness of toilet and kitchen doors should pay special attention to the thickness of wall tiles. Generally, one-sided stickers are 25 feet thicker and two-sided stickers are 50 feet thicker. The specific situation is confirmed by the signature of designers, customers and decoration companies. The final size should include the thickness of the wall brick. It's better to measure the wall tiles after they are affixed.

　　10.测量时注意门的开启方向，开启方向定义为：从门的正面看，把手在左为左开，把手在右为右开。

　　10. Pay attention to the opening direction of the door when measuring. The opening direction is defined as: from the front of the door, the handle opens left and the handle opens right.

　　11.哑口、窗套测量基本上同门洞测量一样，只是尺寸按实际测量结果记录，不用扣除。

　　11. The measurement of dumb mouth and window sleeve is basically the same as that of door-hole measurement, except that the dimensions are recorded according to the actual measurement results without deduction.

　　哑口：指不装门或不用其他东西屏蔽的墙体开口，比如客厅和阳台、卧室和阳台之间的开口。

　　Dumb mouth: refers to wall openings that are not covered by doors or other things, such as the openings between living room and balcony, bedroom and balcony.
