鋁合金門的合頁稍微不注意使用和保養就很容易損壞，實際上鋁合金門合頁壞了是沒有辦法修好的，只有更換同一型號的合頁。在更換新的合頁的時候，要將原來壞了的合頁拆卸下來。具體的拆卸方法與步驟如下：

The hinges of aluminum alloy doors are easy to be damaged if they are not used and maintained slightly. In fact, there is no way to repair the broken hinges of aluminum alloy doors, so we have to replace the hinges of the same model. When replacing a new hinge, remove the original broken hinge. The specific disassembly methods and steps are as follows:

1、查看舊合頁的情況。這一步主要看原來的舊合頁是裝了三個還是兩個，具體的安裝位置，以及合頁的類型。更換新合頁應該盡量選擇和舊合頁相同規格的，而且數量也應該跟之前保持一致。

1. Check the condition of the old hinge. This step mainly depends on whether the original old hinges are installed with three or two, the specific installation location, and the type of hinge. When replacing new hinges, try to choose ones with the same specifications as the old ones, and the number should be the same as before.

2、拆掉原來的舊合頁。利用螺絲刀或者是其他的工具，將原來合頁上的固定部分拆下來，然后清理好門框門扇上的問題，比如門框門扇有缺口等問題。

2. Remove the old hinge. Use a screwdriver or other tools to remove the fixed part on the original hinge, and then clean up the remaining problems on the door frame and door leaf, such as the gap in the door frame and door leaf.

3、找準合頁的安裝位置。如果原來的安裝位置可以繼續利用的話，建議在原來的地方安裝。如果原來的位置無法將合頁安裝緊的話，可以更換位置。但安裝位置的選擇一定要結合門的尺寸來定。

3. Find the installation position of the hinge. If the original installation location can continue to be used, it is recommended to install it in the original location. If the hinge cannot be installed tightly in the original position, the position can be changed. However, the selection of installation position must be determined in combination with the size of the door.

4、安裝并測試成果。將新的合頁按照正確的方式安裝好，安裝完之后要記得測試成果。比如多開門、關門，看看門是否會出現松動、傾斜等情況，如果沒有，則說明安裝成功了。

4. Install and test the results. Install the new hinge in the correct way, and remember the test results after installation. For example, open and close more doors to see whether the guard door will be loose or inclined. If not, the installation is successful.

濟南卷簾門廠家在這里為您介紹下鋁合金門的安裝步驟：

Jinan roller shutter door manufacturer is here to introduce the installation steps of aluminum alloy doors:

根據設計圖紙中門的安裝位置、尺寸和標高,依據門中線向兩邊量出門邊線。

According to the installation position, size and elevation of the door in the design drawing, measure the side line of the door from the center line of the door to both sides.

門框四周外表面的防腐處理設計有要求時,按設計要求處理；如果沒有要求，可涂刷防腐涂料或粘貼塑料薄膜進行保護,以免水泥砂漿直接與鋁合金門表面接觸，腐蝕鋁合金門。

When there are requirements for the anti-corrosion treatment design of the outer surface around the door frame, it shall be treated according to the design requirements; If there is no requirement, it can be painted with anti-corrosion paint or pasted with plastic film for protection, so as to prevent the cement mortar from directly contacting the surface of the aluminum alloy door and corroding the aluminum alloy door.

根據劃好的門定位線,安裝鋁合金門框。并及時調整好門框的水平、垂直及對角線長度等符合質量標準,然后用木楔臨時固定。

Install the aluminum alloy door frame according to the marked door positioning line. And timely adjust the horizontal, vertical and diagonal length of the door frame to meet the quality standards, and then temporarily fix it with a wooden wedge.

墻體上預埋有鐵件時,可直接把鋁合金門的鐵腳直接與墻體上的預埋鐵件焊牢,焊接處需做防銹處理；墻體上若沒有預埋鐵件，可用金屬膨脹螺栓或塑料膨脹螺栓將鋁合金門的鐵腳固定到墻上。

When iron parts are embedded on the wall, the iron foot of the aluminum alloy door can be directly welded with the embedded iron parts on the wall, and the welding place needs to be treated with rust prevention; If there are no embedded iron parts on the wall, metal expansion bolts or plastic expansion bolts can be used to fix the iron feet of aluminum alloy doors to the wall.

按設計要求處理門窗框與墻體之間的縫隙，如果未要求,可采用彈性保溫材料或玻璃棉氈條分層填塞縫隙,外表面留5～8mm深槽口填嵌嵌縫油膏或密封膠。

Treat the gap between the door and window frame and the wall according to the design requirements. If it is not required, use elastic insulation materials or glass wool felt to fill the gap layer by layer, and leave a 5 ~ 8mm deep notch on the outer surface to fill with caulking paste or sealant.
