（1)在石材电梯门套前，首先进行结构找平、套方，根据实际洞口尺寸加工所有材料，在选材时也可对花型做调整，进行Z原始的加工。在施工时按加工的尺寸再次复核，按原来加工的编号进行分类“对号入座”。

(1) Before using the stone elevator door frame, first level and square the structure, and process all materials according to the actual hole size. When selecting materials, the pattern can also be adjusted to perform the original Z processing. During construction, recheck according to the processed size and classify according to the original processing number for "matching and positioning".

（2)在地面目测与电梯侧框垂直贴50mm宽的地胶带，用1个方尺（长度500mm为宜）以电梯门下框为底，用方尺划电梯门底框的垂线，线一定要划在纸胶带上，划线要清晰，长度大于砌体厚度（洞口侧边宽度）。

(2) Visually stick a 50mm wide ground tape perpendicular to the elevator side frame on the ground, and use a square ruler (preferably 500mm in length) to draw the vertical line of the elevator door bottom frame with the bottom frame of the elevator door as the bottom. The line must be drawn on the paper tape, and the marking should be clear and the length should be greater than the thickness of the masonry (width of the opening side).

（3)用卷尺测量内门套侧板石材、固定件总厚度，以划的垂线为基准线，量取相同尺寸，对基准线进行平移，找出交点，这样门套内侧板靠近门框处的点即可确定。

(3) Measure the total thickness of the stone and fixing parts on the inner door frame side panel with a tape measure. Use the perpendicular line as the reference line, measure the same size, translate the reference line, and find the intersection point. This way, the point near the door frame on the inner side panel of the door frame can be determined.

（4)以墙面向基准线画垂线，根据情况制订合理的“八”字口尺寸及效果，在垂线上量取尺寸，找出交点，确定石材门套内侧板外端点。将2点连成1条直线，这样内侧套一边的底边就确定了，然后进行安装。同时利用四线红外线检查垂直度。用同样的方法和尺寸确定另一侧内套板。这样两侧板即可安装。

(4) Draw a vertical line from the wall to the reference line, formulate a reasonable size and effect of the "eight" shaped opening according to the situation, measure the size on the vertical line, find the intersection point, and determine the outer endpoint of the inner side panel of the stone door frame. Connect the two points into a straight line, so that the bottom edge of one side of the inner sleeve is determined, and then proceed with installation. Simultaneously use four line infrared to check verticality. Use the same method and size to determine the inner sleeve plate on the other side. This way, the two side panels can be installed.

（5)门套内侧顶板安装注意点，顶板尺寸比洞口尺寸两边大30mm,确保顶板搁置于两侧板上，顶板内木条作好防腐，固定在内，主要作用是防止堵塞物不实及漏浆问题。顶板用专业胶粘结在已找方正、清理干净的基层上。

(5) Attention points for the installation of the inner top plate of the door frame. The size of the top plate is 30mm larger than the size of the opening on both sides. Ensure that the top plate is placed on both sides of the board, and the wooden strips inside the top plate are well protected against corrosion and fixed inside. The main function is to prevent blockages and slurry leakage. The top plate is bonded with professional adhesive to the square and cleaned base layer.

（6)全部安装完，掀掉保护膜，并用棉丝把石材门套擦干净。

(6) After installation is complete, remove the protective film and wipe the stone door cover clean with cotton thread.

（7)所有拼缝处打结构胶，结构胶的」选用颜色尽量与石材颜色相同或接近，打胶前用纸胶带对周边进行保护，以免造成二次污染。

(7) Apply structural adhesive to all joints, and the selected color of the structural adhesive should be as close or identical to the color of the stone as possible. Before applying the adhesive, protect the surrounding area with paper tape to avoid secondary pollution.

（8)掀去纸胶带，清理干净。该做法经项目实地使用，整体效果良好。充分体现出在不改变电梯门的前提下，通过“八”字口来增大洞口尺寸，方便人和小型推车的进入提高洞口利用率。

(8) Remove the paper tape and clean it thoroughly. This method has been used on the project site and the overall effect is good. This fully demonstrates that, without changing the elevator door, the size of the opening can be increased through the "eight" shaped opening, which facilitates the entry of people and small carts and improves the utilization rate of the opening.
