（1)在石材電梯門套前，首先進行結構找平、套方，根據實際洞口尺寸加工所有材料，在選材時也可對花型做調整，進行Z原始的加工。在施工時按加工的尺寸再次復核，按原來加工的編號進行分類“對號入座”。

(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)在地面目測與電梯側框垂直貼50mm寬的地膠帶，用1個方尺（長度500mm為宜）以電梯門下框為底，用方尺劃電梯門底框的垂線，線一定要劃在紙膠帶上，劃線要清晰，長度大于砌體厚度（洞口側邊寬度）。

(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)用卷尺測量內門套側板石材、固定件總厚度，以劃的垂線為基準線，量取相同尺寸，對基準線進行平移，找出交點，這樣門套內側板靠近門框處的點即可確定。

(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)以墻面向基準線畫垂線，根據情況制訂合理的“八”字口尺寸及效果，在垂線上量取尺寸，找出交點，確定石材門套內側板外端點。將2點連成1條直線，這樣內側套一邊的底邊就確定了，然后進行安裝。同時利用四線紅外線檢查垂直度。用同樣的方法和尺寸確定另一側內套板。這樣兩側板即可安裝。

(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)門套內側頂板安裝注意點，頂板尺寸比洞口尺寸兩邊大30mm,確保頂板擱置于兩側板上，頂板內木條作好防腐，固定在內，主要作用是防止堵塞物不實及漏漿問題。頂板用專業膠粘結在已找方正、清理干凈的基層上。

(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)全部安裝完，掀掉保護膜，并用棉絲把石材門套擦干凈。

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

（7)所有拼縫處打結構膠，結構膠的」選用顏色盡量與石材顏色相同或接近，打膠前用紙膠帶對周邊進行保護，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)掀去紙膠帶，清理干凈。該做法經項目實地使用，整體效果良好。充分體現出在不改變電梯門的前提下，通過“八”字口來增大洞口尺寸，方便人和小型推車的進入提高洞口利用率。

(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.
