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.

而原电梯门洞的大小是取决于电梯载重标准来计算的，相关规范上对于建筑的电梯设置数量，各个电梯载重数量，对应的电梯规范大小，以及电梯门洞大小，都是有规范规定的，且规定的相当详细。

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.

根据上面两张图的对比，我们可以看出，电梯门套是由两个部分门套构成的：

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

一部分是电梯构造自身的钢门套，也是我俗称的“小门套”;

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

一部分是由装饰材料做的装饰门套，也就是我们大多数设计师认为的电梯门套。

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.

从材质上看：电梯门套一般是钢框，而装饰门套可以是各种各样的材质;

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;

从位置关系上看：普通门套靠近室内空间，而电梯门套靠近电梯井;

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：采用镀锌铁皮封堵是为了避免电梯上下产生外力，对电梯门套结构造成破坏。

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.

从功能上来看：装饰门套是为了满足室内空间的美观性，而电梯门套则是满足楼梯层门的功能性而存在的。为了保证电梯门套的美观性，我们通常会用采用装饰门套包裹住电梯门套的构造做法来对电梯门套进行处理;

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，在已经完工的项目中，我们是看不见电梯门套的。

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

而从设计制图的角度上来说，电梯门套主要是由建筑单位绘制的，装饰门套是由我们绘制，所以，在我们绘制电梯相关节点时，应查阅相对应的土建图纸，看看土建的门洞与装饰的门洞是否能够对应上，再进行下一步行动。

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.
