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

1.在安装时先要将各层需要的石材挑选好。根据尺寸、颜色和花纹来搭配，然后搬运到各个楼层需要使用的地方。

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.在安装时要注意石材的纹理，尽量保持色泽一致，纹理连贯。安装完成之后，电梯门套的美观性才会较佳。

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.弹线的时候要仔细测量，不仅一个门套要做好垂直和平整性，每个门套之间也要注意这些问题。

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.在安装侧板和线条时，要保证至少有2个挂件作为支撑件。安装角钢的位置要测量准确，在中间增加一个加固点的点位。这样做是为了让门套石材更加稳定、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.安装时不要靠得太紧，在电梯门框边预留5mm到8mm的位置，注意让四周的预留位保持一致。

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.在安装槛石时，地砖和电梯框边要有3mm左右的坡度，门框边和顶面石材外口要有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.顶面线条碰和侧面线条的角度为45°，碰角做到严密、平整，施工时注意缝隙内不留余胶。如果有余胶就及时清理掉，然后使用勾缝剂处理。线条大小一致，造型稳合整体风格。

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.在使用云石胶打点之后，还要使用专用的AB胶固定，这样才能确保稳定性。

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

9.全部安装完成后，即使进行现场清理工作，还有做好调色勾缝处理?；挂⒁舛允难艚堑谋；ぃ门菽そ墙鹄?。这样能避免受到碰撞损坏。

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.
