1、根據設計圖紙檢查門的規格、測量尺寸等。

　　1. Check the specifications, measurement dimensions, etc. of the door according to the design drawings.

　　2、用卷尺量門洞的高與寬，需木龍骨回填大小尺寸，左右位置，并詳細標明。

　　2. Measure the height and width of the door opening with a tape measure, and fill the wooden keel with dimensions, left and right positions, and indicate them in detail.

　　3、測量位置線，確定木龍骨的位置，用墨斗彈拉出垂直線，一側門洞兩條垂直線。

　　3. Measure the position line, determine the position of the wooden keel, use an ink fountain to pull out a vertical line, and draw two vertical lines on one side of the door opening.

　　4、在垂直線上用沖擊鉆打眼，孔眼與孔眼之間的距離約為30cm，一側門兩排共10個孔眼。沖擊鉆的鉆頭應為12mm，所鉆孔眼約為6cm。

　　4. Drill holes with an impact drill on the vertical line, with a distance of about 30cm between each hole. There are a total of 10 holes in two rows on one side of the door. The drill bit of the impact drill should be 12mm, and the drilled hole should be about 6cm.

　　5、將小木楔用鐵錘逐個釘入孔眼，以便固定龍骨板。小木楔的體積大小為5cm×1.5cm×1.5cm，以落葉松制作的為好，因為落葉松的木質結構緊，不容易松動。

　　5. Nail the small wooden wedges into the holes one by one with a hammer to fix the keel board. The volume size of the small wooden wedge is 5cm × 1.5cm × 1.5cm, and it is better to make it from larch because the wood structure of larch is tight and not easy to loosen.

　　6、開料制作門框。左右做兩側門框龍骨的木工板門框頂龍骨的木工將高密度九厘板涂膠粘在龍骨上，再用釘子固定。

　　6. Cutting materials to make door frames. The carpenter who makes the door frame keel on both sides of the door frame will apply glue to the high-density 9cm board and stick it to the keel, and then fix it with nails.

　　7、將制作好的三條門框按門的形狀連接起來，并且用大釘子在接合處固定。

　　7. Connect the three pre made door frames according to the shape of the door and fix them at the joint with large nails.

　　8、用刨子將連接好的門框表面修平整，修整邊角，棱角分明。

　　8. Use a planer to smooth the surface of the connected door frame, trim the edges and corners, and make them sharp and angular.

　　9、將門框放到門洞上，按墻面的水平線為準，門框下拿木頭或者磚頭墊起，調節門框的高度。下面預留5cm埋在地板的龍骨中。

　　9. Place the door frame on the doorway, aligning it with the horizontal line of the wall. Use wood or bricks to support the frame and adjust its height. Reserve 5cm below to be buried in the keel of the floor.

　　10、在門框的上面釘一個釘子，把線垂掛上，通過線垂來調整門框的垂直（也可根據電梯小門框的水平垂直），一邊衡量一邊用麻花釘將門框固定在門洞墻上。

　　10. Nail a nail on the door frame, hang the line vertically, adjust the verticality of the door frame through the line verticality (also according to the level and verticality of the elevator small door frame), and use Fried Dough Twists nails to fix the door frame on the door opening wall while measuring.

　　11、按照甲方要求，刷三到五遍防火涂料（甲方未要求可以不做）

　　11. According to the requirements of Party A, apply three to five coats of fireproof coating (if not requested by Party A, it can be omitted)

　　12、測量準確的龍骨回填尺寸，按照測量尺寸下料不銹鋼，等待防火涂層干透。

　　12. Measure the accurate size of the keel backfill, cut stainless steel according to the measured size, and wait for the fireproof coating to dry completely.

　　13、不銹鋼進場后按照標準尺寸和不銹鋼所在位置，一一對應放到門洞位置，切不可亂拿。

　　13. After the stainless steel enters the site, it should be placed in the door opening position according to the standard size and location of the stainless steel, and must not be taken randomly.

　　14、刷膠水，待膠水處于似粘非粘狀態時，粘貼不銹鋼。務必一次性安裝到位，貼上之后不能拿下，并且拍實，防止后期起鼓分層。

　　14. Brush the glue, and when the glue is in a non stick state, stick the stainless steel. Be sure to install it in place at once, do not remove it after pasting, and press it firmly to prevent later bulging and layering.

　　15.電梯門套全部安裝完成后，用泡沫護角將它包裹起來，這樣能避免受到碰撞損壞。

　　15. After all elevator door jambs are installed, wrap them with foam corner protectors to avoid collision damage.
