The specification and scale of elevator door are divided into two cases: one is the size of the original elevator door opening reserved when building the elevator shaft; Second, the final size of the door opening after interior decoration.

而原電梯門洞的大小是取決于電梯載重標準來計算的，相關規范上對于建筑的電梯設置數量，各個電梯載重數量，對應的電梯規范大小，以及電梯門洞大小，都是有規范規定的，且規定的相當詳細。

The size of the original elevator door opening depends on the elevator load standard. In relevant specifications, the number of elevators set in the building, the load number of each elevator, the corresponding elevator specification size and the size of elevator door opening are specified in specifications, and the provisions are quite detailed.

根據上面兩張圖的對比，我們可以看出，電梯門套是由兩個部分門套構成的：

According to the comparison of the above two figures, we can see that the elevator door pocket is composed of two parts:

一部分是電梯構造自身的鋼門套，也是我俗稱的“小門套”;

One part is the steel door pocket of the elevator structure itself, which is also commonly known as "small door pocket";

一部分是由裝飾材料做的裝飾門套，也就是我們大多數設計師認為的電梯門套。

One part is the decorative door pocket made of decorative materials, which is what most of our designers think of as the elevator door pocket.

從材質上看：電梯門套一般是鋼框，而裝飾門套可以是各種各樣的材質;

From the material point of view: the elevator door pocket is generally steel frame, while the decorative door pocket can be a variety of materials;

從位置關系上看：普通門套靠近室內空間，而電梯門套靠近電梯井;

From the perspective of location relationship: the ordinary door pocket is close to the indoor space, while the elevator door pocket is close to the elevator shaft;

Ps：采用鍍鋅鐵皮封堵是為了避免電梯上下產生外力，對電梯門套結構造成破壞。

PS: galvanized iron sheet is used for sealing to avoid external force generated by the elevator up and down and damage to the elevator door pocket structure.

從功能上來看：裝飾門套是為了滿足室內空間的美觀性，而電梯門套則是滿足樓梯層門的功能性而存在的。為了保證電梯門套的美觀性，我們通常會用采用裝飾門套包裹住電梯門套的構造做法來對電梯門套進行處理;

From the perspective of function: the decorative door pocket is to meet the aesthetics of indoor space, while the elevator door pocket exists to meet the functionality of stair landing door. In order to ensure the beauty of the elevator door pocket, we usually use the structural method of wrapping the elevator door pocket with decorative door pocket to deal with the elevator door pocket;

因此，在已經完工的項目中，我們是看不見電梯門套的。

Therefore, in the completed project, we can't see the elevator door pocket.

而從設計制圖的角度上來說，電梯門套主要是由建筑單位繪制的，裝飾門套是由我們繪制，所以，在我們繪制電梯相關節點時，應查閱相對應的土建圖紙，看看土建的門洞與裝飾的門洞是否能夠對應上，再進行下一步行動。

From the perspective of design and drawing, the elevator door pocket is mainly drawn by the construction unit, and the decorative door pocket is drawn by us. Therefore, when we draw the relevant nodes of the elevator, we should consult the corresponding civil engineering drawings to see whether the civil door opening can correspond to the decorative door opening, and then take the next step.
