(1)鋁合金門窗加工前，;應(yīng)對所用材料和附件進行檢驗，其材質(zhì)應(yīng)符合現(xiàn)行國家標(biāo)準(zhǔn)或行業(yè)標(biāo)準(zhǔn)，所選用的型材形狀、尺寸及壁厚應(yīng)符合設(shè)計和使用要求。選用的附件，除不銹鋼外，應(yīng)做防腐處理，以防止與鋁合金型材發(fā)生接觸腐蝕。

(2)應(yīng)認真檢查門窗洞口的實際尺寸，并根據(jù)土建施工圖核實洞口的實際尺寸與設(shè)計要求是否相符，若有出入，應(yīng)會同土建部門共同處理。

(3)檢查施工工具、機具。

(二)鋁合金門窗的制作方法

(1)斷料。斷料，又稱“下料”，是鋁合金門窗制作的靠前道工序，也是關(guān)鍵的工序。斷料主要使用切割設(shè)備，材料長度應(yīng)根據(jù)設(shè)計要求并參考門窗施工大樣圖來確定，要求切割準(zhǔn)確;否則，門窗的方正難以保證，斷料尺寸誤差值應(yīng)控制在2mm范圍內(nèi)。一般來說，推拉門窗斷料宜采用直角切割;平開門窗斷料宜采用45°角切割;其它類型應(yīng)根據(jù)拼裝方式來選用切割方式。

(2)鉆孔。鋁合金門窗的框扇組裝一般采用螺絲連接，因此不論是橫豎桿件的組裝，還是配件的固定，均需要在相應(yīng)的位置鉆孔。型材鉆孔，可以用小型臺鉆，前者由于有工作臺，所以能有效保證鉆孔位置的準(zhǔn)確度;而后者是因為操作方便。

鉆孔前應(yīng)根據(jù)組裝要求在型材上彈線定位，要求鉆孔位置準(zhǔn)確，孔徑合適，不可在型材表面反復(fù)更改鉆孔，因為孔一旦形成，則難以修復(fù)。

(3)組裝。將型材根據(jù)施工大樣圖要求通過連接件用螺絲連接組裝。鋁合金門窗的組裝方式有45°角對接、直角對接和垂直對接三種。橫豎桿的連接，一般采用專項使用的連接件或鋁角，再用螺釘、螺栓或鋁拉釘固定。鋁合金門窗的組裝質(zhì)量，應(yīng)符合下列規(guī)定：①門窗裝飾表面不應(yīng)有明顯的損傷。每樘門窗局部擦傷、劃傷，不應(yīng)超過表1的規(guī)定。②門窗上相鄰構(gòu)件著色表面不應(yīng)有明顯的色差。③門窗表面應(yīng)無鋁屑、毛刺、油斑或其它污跡存在。裝配連接處不應(yīng)有外溢的膠粘劑。④門窗框尺寸偏差，應(yīng)符合表2的規(guī)定。⑤門窗框、扇相鄰構(gòu)件裝配間隙及同一平面高低差，應(yīng)符合表3的規(guī)定。

( 1 ) aluminum windows and doors processing ; respond materials and accessories used to test , the material should be consistent with existing national standards or industry standards , the choice of profile shape, size and wall thickness shall meet the design and use requirements . Optional accessories, other than stainless steel , should be treated with preservatives to prevent contact corrosion with aluminum profiles .

( 2 ) should carefully check the actual size of window and door openings , and to verify the actual size and design are consistent with the requirements of the hole , if access should be handled in conjunction with the civil authorities in accordance with the common civil construction plans .

( 3 ) Check the construction tools , machines and tools .

( B) The method of making aluminum windows and doors

( 1 ) broken material . Broken material , also known as " cutting ", is the first step of the production of aluminum windows and doors , as well as key processes. Feed off the main use cutting equipment , materials and design requirements should be based on the length of the reference windows large drawing to determine the construction , requiring cutting accurate ; otherwise difficult to ensure Founder doors , broken feed size error value should be controlled within the range of 2mm . Generally, sliding doors and windows should be used at right angles to cut off the material ; door windows broken material should adopt a 45 ° angle cutting ; other types of selection should be based approach to assembling cutting mode .

( 2 ) drilling. Aluminum doors and windows box fan assembly generally use screw connection, so both horizontal and vertical rod assembly , or parts of the fixed , need to drill holes in the corresponding position . Profiles drilling, you can use a small bench or pistol drills, the former due to the table , they are able to effectively guarantee the accuracy of the drilling location ; while the latter is due to ease of operation .

Elastic line before drilling should be positioned in accordance with the requirements in sections assembled , requiring accurate drilling position , aperture appropriate changes can not be repeated in the profile surface drilling holes because once formed, it is difficult to repair.

( 3 ) assembly . The large drawing shapes according to the construction requirements connected with screws through the connector assembly . Aluminum windows and doors have a 45 ° angle assembly methods butt , butt right angle and vertical docking three. Connecting rod anyway , generally use a dedicated connection or aluminum angle , and then screws, bolts or aluminum pull nails . Assembly of quality aluminum windows and doors , shall comply with the following requirements : ① doors decorated surface should not have obvious damage. Doors and door frames every local scrapes , scratches, should not exceed specified in Table 1 . Members colored surface adjacent ② doors should not have obvious color difference . ③ aluminum doors and windows should be no surface debris , burrs , oil spots or other stains exist. There should be no spillover junction assembly adhesives . ④ door frame size deviation , shall meet the requirements of Table 2. ⑤ door frames , fan assembly space adjacent components and the same plane as the height difference , should meet the requirements of Table 3 .
