The measurement of elevator sleeves is basically the same as that of door and window sleeves. The reason why elevator sleeves are separately mentioned is because the size of elevator sleeves is determined by the elevator opening and elevator door frame of the original building, which is a big difference from the measurement of door and window sleeves.

1、电梯门套线是沿电梯门洞的四周（没有顶到楼层的顶部）

1. The elevator door pocket line runs along the perimeter of the elevator door opening (without reaching the top of the floor)

这是常规基本的电梯套施工方式，简单的都让人不想去叙述。可是正是因为能把基本的问题想明白了，我们面对非常规才能更游刃有余。

This is a conventional and basic construction method for elevator sleeves, and even the simple ones are difficult to describe. But it is precisely because we can understand the basic problems that we can face unconventional situations more easily.

由于电梯门框的尺寸是固定的，就决定了两个侧板之间的距离也是固定的。

Due to the fixed size of the elevator door frame, the distance between the two side panels is also fixed.

顶板的长度也就是两个侧板之间的距离加上两块侧板的厚度。侧板的高度也是由电梯门框的高度决定的，和门框的高度一样高。侧板和顶板的宽度，要在门洞的上中下取三个点去量电梯门框到墙壁的外侧的距离，取它们当中大的距离作为电梯侧板和顶板的宽度。

The length of the top plate is the distance between the two side plates plus the thickness of the two side plates. The height of the side panel is also determined by the height of the elevator door frame, which is the same height as the door frame. The width of the side panel and top panel should be measured at three points on the top, middle, and bottom of the door opening to measure the distance from the elevator door frame to the outside of the wall. The larger distance between them should be taken as the width of the elevator side panel and top panel.

电梯门套线的宽度必须要能完全的把墙壁和侧板之间的距离遮住。

The width of the elevator door pocket line must be able to completely cover the distance between the wall and the side panel.

电梯门套线的长度就是电梯侧板的高度加上线条本身的宽度，当然线条的长度可以适当的放长几公分，防止工人现场施工切45度角时出现失误，长一点还可以切成短的，短的就再也不能变成长的了。有的时候门套线的下方还会有个小脚座，宽度和线条相同，高度不定。这时线条的长度就再减去脚座的高度。

The length of the elevator door cover line is the height of the elevator side panel plus the width of the line itself. Of course, the length of the line can be appropriately extended by a few centimeters to prevent workers from making mistakes when cutting at a 45 degree angle during on-site construction. If it is longer, it can be cut into shorter ones, and the shorter ones can no longer grow. Sometimes there is a small foot seat below the door pocket line, with the same width and line, but varying height. At this point, the length of the line is then subtracted from the height of the footrest.

2.电梯门套直接到顶

2. The elevator door pocket goes directly to the top

图1的电梯套沿门洞四周粘贴，那么门洞四周的墙面肯定在同一垂直平面上，而现在这种线条到顶的方式就得分两种情况了。

The elevator cover in Figure 1 is pasted along the perimeter of the door opening, so the walls around the door opening must be in the same vertical plane. However, the current method of reaching the top of the line is divided into two situations.

原建筑墙面（也可以理解成，施工方为了节约材料没在阴影处贴瓷砖，和石材面板重复了。所以阴影处相当于四周的墙壁是凹进去的）。

The original building wall (which can also be understood as the construction party did not apply tiles in the shadow area to save materials, and repeated it with the stone panel. Therefore, the shadow area is equivalent to the surrounding walls being recessed).

这种情况对我们确定面板的尺寸是有利的，面板的作用就相当于用瓷砖把阴影部分填平，使门套四周再处于同一垂直面。门套线条是可以压着面板的。所以面板的长度不大于两侧瓷砖之间的距离，并且不小于电梯套两侧板之间的距离。

This situation is beneficial for us to determine the size of the panel, as the function of the panel is to fill the shaded area with tiles, so that the door jamb is placed on the same vertical surface all around. The door pocket lines can be pressed against the panel. So the length of the panel should not be greater than the distance between the tiles on both sides, and should not be less than the distance between the panels on both sides of the elevator sleeve.

面板的宽度就是用总高减去电梯门框的高度，这是面板宽的宽度，因为顶部的电梯套线条是压着它的，所以面板的宽度还可以减少，但是不能减少的超过线条的宽度。侧板和顶板的长和宽和1中的测量方法是一样的。在此不在赘述。

The width of the panel is calculated by subtracting the height of the elevator door frame from the total height. This is the width of the panel, as the top elevator sleeve line is pressed against it. Therefore, the width of the panel can be reduced, but cannot exceed the width of the line. The length and width of the side panel and top panel are measured using the same method as in 1. I won't go into detail here.

阴影部分和四周处于同一垂直面（简单理解就是贴了瓷砖了），这时电梯门套线条就不能再压着面板了，如果要压着了，就相当于把线条从墙上抬高了一段距离（这个距离可以想成是面板的厚度18加上胶口厚度6）.线条和墙壁之间就需要用收口条收口。

The shaded area is on the same vertical plane as the surrounding area (simply understood as having tiles applied), so the elevator door cover line can no longer press against the panel. If it needs to be pressed, it is equivalent to lifting the line a certain distance from the wall (this distance can be thought of as the thickness of the panel of 18 plus the thickness of the adhesive opening of 6). A closing strip needs to be used to close the line between the line and the wall.

想想两三公分的长条会出现多高的损耗，而且增加了施工难度，同时侧板和顶板的宽度也要随之增加。见下图。

Think about how high the loss of a 2-3 centimeter strip will be, and it will increase the difficulty of construction, while also increasing the width of the side and top plates. See the figure below.

所以这种情况下面板的尺寸要很精确才行。它的长度就是两块侧板之间的距离，也就是电梯门框的宽度，它的高度就是用地面距顶的总高度减去电梯门框的高度再减去门套线条的宽度。

So in this case, the size of the panel needs to be very precise. Its length is the distance between two side panels, which is the width of the elevator door frame. Its height is the total height from the ground to the top minus the height of the elevator door frame and then minus the width of the door pocket line.

或者用电梯门框距顶的高度减去门套线条的宽度。而且在施工时要向施工负责人明确粘贴时首先要固定好面板的位置，这样就等于是给两个侧板的间距固定了，才不会因为侧板安装时它们之间距误差影响到面板，否则别人又会说是面板的尺寸下小了，其实是因为施工的顺序搞错了。

Alternatively, subtract the width of the door pocket line from the height of the elevator door frame from the top. And during construction, it is necessary to clarify to the construction manager that the position of the panel should be fixed first when pasting. This is equivalent to fixing the spacing between the two side panels, so that the panel will not be affected by the distance error between them during installation. Otherwise, others may say that the size of the panel is too small, but it is actually because the construction sequence is wrong.

或者怕麻烦的情况下，就和施工负责人商量，把面板的尺寸按照1中的情况测量，把尺寸放大一点，施工的时候，等到门套线贴上去之后，现场量好两根门套线条之间的距离和顶板距顶部门套线条的距离，再手工切割。

Or if you are afraid of trouble, discuss with the construction manager to measure the size of the panel according to the situation in 1. Enlarge the size a bit. During construction, wait until the door jamb line is attached, measure the distance between the two door jamb lines on site and the distance between the top plate and the top department's line, and then manually cut.

手工切割也有技巧，在石材见光面贴上美纹纸，画好线，然后切割，这样可以减少崩边的发生。

There are also techniques for manual cutting, such as pasting textured paper on the smooth surface of the stone, drawing lines, and then cutting, which can reduce the occurrence of edge chipping.
