What should be noted during the installation process of door jambs.

1.在安裝時先要將各層需要的石材挑選好。根據尺寸、顏色和花紋來搭配，然后搬運到各個樓層需要使用的地方。

1. When installing, it is necessary to first select the required stones for each layer. Match according to size, color, and pattern, and then transport to the required locations on each floor.

2.在安裝時要注意石材的紋理，盡量保持色澤一致，紋理連貫。安裝完成之后，電梯門套的美觀性才會較佳。

2. Pay attention to the texture of the stone during installation, and try to maintain consistent color and texture consistency. After the installation is completed, the aesthetics of the elevator door cover will be better.

3.彈線的時候要仔細測量，不僅一個門套要做好垂直和平整性，每個門套之間也要注意這些問題。

3. When snapping the line, careful measurement should be taken. Not only should one door jamb be vertical and flat, but also attention should be paid to these issues between each door jamb.

4.在安裝側板和線條時，要保證至少有2個掛件作為支撐件。安裝角鋼的位置要測量準確，在中間增加一個加固點的點位。這樣做是為了讓門套石材更加穩定、牢固。

4. When installing side panels and lines, ensure that there are at least 2 hanging parts as support components. The installation position of the angle steel should be accurately measured, and a reinforcement point should be added in the middle. This is to make the door jamb stone more stable and firm.

5.安裝時不要靠得太緊，在電梯門框邊預留5mm到8mm的位置，注意讓四周的預留位保持一致。

5. During installation, do not lean too tightly. Reserve a 5mm to 8mm position on the edge of the elevator door frame, and ensure that the reserved spaces around are consistent.

6.在安裝檻石時，地磚和電梯框邊要有3mm左右的坡度，門框邊和頂面石材外口要有2mm左右的斜度。

When installing sill stones, the floor tiles and elevator frame edges should have a slope of about 3mm, and the outer opening of the door frame edge and top stone should have a slope of about 2mm.

7.頂面線條碰和側面線條的角度為45°，碰角做到嚴密、平整，施工時注意縫隙內不留余膠。如果有余膠就及時清理掉，然后使用勾縫劑處理。線條大小一致，造型穩合整體風格。

7. The angle between the top line and the side line is 45 °, and the angle should be tight and flat. During construction, attention should be paid to not leaving any adhesive residue in the gaps. If there is any excess glue, clean it up in a timely manner and then use a pointing agent for treatment. The line size is consistent, and the shape is stable and in line with the overall style.

8.在使用云石膠打點之后，還要使用專用的AB膠固定，這樣才能確保穩定性。

After using marble glue for dotting, special AB glue should also be used for fixation to ensure stability.

9.全部安裝完成后，即使進行現場清理工作，還有做好調色勾縫處理。還要注意對石材陽角的保護，用泡沫護角將它包裹起來。這樣能避免受到碰撞損壞。

9. After all installation is completed, even if on-site cleaning work is carried out, color matching and pointing treatment should be done well. Pay attention to the protection of the external corner of the stone, and wrap it with foam corner protectors. This can avoid collision damage.
