Elements of Selecting Aluminum Alloy Doors and Windows

选好铝合金门窗的要素



Compared with push-pull windows, aluminium alloy flat doors have the characteristics of good sealing, high safety and more harmony with the overall style of buildings. However, because of the high cost, they were used in commercial and residential buildings, office buildings, high-grade residential buildings, villas and other high-grade buildings in some cities. With the progress of people's living standards, aluminium alloy flat windows are in use. Common residential areas are also beginning to be widely used.

铝合金平开门相对推拉窗具有密封性好,安全度高,与建筑物整体风格更和谐等特点,但因为造价较高,以前多在一些城市的商住楼、写字楼、高档住宅、别墅等中高档建筑应用,跟着人们糊口水平的进步,铝合金平开窗的在普通小区也开始广泛应用。




Compared with push-pull windows, aluminium alloy flat doors have the characteristics of good sealing, high safety and more harmony with the overall style of buildings. However, because of the high cost, they were used in commercial and residential buildings, office buildings, high-grade residential buildings, villas and other high-grade buildings in some cities. With the progress of people's living standards, aluminium alloy flat windows are in use. Ordinary residential areas have also begun to be widely used, the impact of aluminium alloy flat window five properties (air tightness, water tightness, wind pressure resistance, sound insulation, heat insulation), in addition to profiles and hardware, the role of sealant can not be underestimated, a set of aluminium alloy doors and windows, often because of people's neglect of sealant, resulting in aluminium alloy doors and windows not sealed cases. There are plenty of sub-products; there are many materials related to sealant strips, you can also refer to the scale JGT/187-2006. With qualified materials and unfair mouth design, the seals can not be achieved, and different window shapes have different requirements for rubber strips. Here are some opinions on the selection of sealant strip profile in aluminium alloy flat window.




I. Selection of the Adhesive Strip Mouth in the General Aluminum Alloy Flat Window




Ordinary aluminium alloy flat window (38, 50 series), mostly using internal and external frame two-layer seal, relatively simple, choose the rubber strip mouth note the following points.




1. For example, aluminum alloy doors and windows are installed with a hinge, because the window closure is the process of pressing along the axis of the hinge, the compression of the full-blocked adhesive tape should not be too large, 1_2 mm is enough to prevent the difficulty of closing the side of the installation hinge due to the excessive compression, and the compression of the non-blocked adhesive tape can be 2 3 mm.




2. If the aluminium alloy doors and windows are installed by sliding brace, because the window closure is similar to the parallel pressing process, the compression of the tape can be larger, not more than 3 mm, provided that the locking is not too laborious.




2. Selection of tape moulds in flat open and hanging (inside open and inside inverted) windows




Flat hanging window is a popular window type in the world. The user can handle the window by rotating the window to realize the opening of the window in two ways: flat and hanging down, and the closing of the window. In the lower suspension state, good ventilation can be achieved without occupying indoor space, and thieves can be prevented from entering through windows. Because this window type combines two kinds of operation: flat opening and hanging down, the following points should be noted when using this window type to select the tape shape:




1. Indoor selection of full-blocking type tape compression should not be too large, 1_2 mm is enough, the thickness of the tape is 0.8_0.9 mm is appropriate, too thick or too large compression type easily cause locking problems, or even can not be locked.




2. Indoor tape is recommended to use non-blocking tape with compression of 2 to 3 mm. The condition is that the wall thickness of the adhesive tape is 1 1.3 mm.




3. If the distance between frame and fan is less than 2.5 mm, the compression of non-blocking type rubber strip is recommended to be 0.5 1 mm.




3. Selection of Adhesive Strip Mouth in Aluminum Alloy Flat Opening Window of Heat-insulated Broken Bridge




The principle of insulating bridge is that the insulating strip is pierced between the aluminium profiles, and the aluminium profiles are disconnected to form a broken bridge. Effectively prevent heat transfer. This type of window is mostly made of hollow glass. In addition to the inner and outer frame double seals, an isobaric rubber strip seal is added in the middle. This window type can be said to be the best one for sealing effect at present. It can be assembled into a flat hanging window or an ordinary aluminium alloy flat opening window. The two-layer sealing of the inner and outer frame of this window type can refer to the flat hanging window, but the selection of isobaric tape must pay attention to the following points:




1. Isobaric tape is the key to seal the composite window with insulation and bridge breaking. Because the tape has a certain amount of compression, the aluminum alloy doors and windows need a certain amount of closed cooperation when they are closed. If the interference fit of the isobaric strip is required unilaterally, the window closing will be laborious. Therefore, when the aluminum alloy doors and windows are closed, the interference fit of the B section can be slightly deformed, and the interference fit of the B section is 1 2 mm. And when choosing hardware, the thickness of the hinge should be the same as the design of the manufacturer. Otherwise, it will easily lead to sealing failure of the isobaric rubber strip seal or the window can not be closed.




2. Because the profile cavity is large, and the hollow glass is used, the weight of the window is large, after installation, if the quality of hardware (hinge, sliding brace) is not external, it is very easy to produce the sinking of the non-hinge and non-sliding brace side of the window, that is to say, angle drop, so it is appropriate for the profile factory to design the window shape A > 5mm; C < 3 mm, the assembly plant should be adequate. Considering the weight of the window fan, choose the corresponding hardware to avoid angle drop. The window fan is stuck on the top of the isobaric tape, which causes the window can not be locked.


铝合金平开门相对推拉窗具有密封性好,安全度高,与建筑物整体风格更和谐等特点,但因为造价较高,以前多在一些城市的商住楼、写字楼、高档住宅、别墅等中高档建筑应用,跟着人们糊口水平的进步,铝合金平开窗的在普通小区也开始广泛应用,对铝合金平开窗五性(气密性、水密性、抗风压、隔音、隔热)的影响,除了型材和五金件外,密封胶条的作用不可小觑,一套铝合金门窗,往往因为人们对密封胶条的忽视,造成铝合金门窗不密封的例子比比皆是;关于密封胶条的材料相关先容较多,大家也可参照尺度JGT/187-2006。有了合格的材料,没有公道的口型设计,密封当然也不能达到;而且不同的窗型对胶条的要求也不同。下面就密封胶条口型在铝合金铝合金平开窗中的选用提出一些看法。   


一、普通铝合金平开窗中胶条口型的选用    


普通铝合金平开窗(38、50等系列),多采用内外框两层密封,比较简朴,选用胶条口型留意以下几点。   


1.如铝合金门窗是采用合页安装的,因窗户封闭是沿合页做轴线压合的过程,全封锁口型胶条的压缩量不宜过大,1∽2mm就可以了,防止因压缩量过大,造成安装合页一侧闭合难题,非封锁口型的压缩量2∽3mm都可以。   


2.如铝合金门窗是采用滑撑安装的,因窗户封闭类似平行压合的过程,胶条的压缩量可大些,不超过3mm都可以,条件是锁闭时不太费力即可。  


二、平开下悬(内开内倒)窗中胶条口型的选用    


平开下悬窗是国际上流行的一种窗型。使用者可通过旋转窗执手,实现窗的平开、下悬两种开启方式,以及窗的封闭。在下悬状态时,在不占用室内空间的情况下,可实现良好的透风,还可以防止偷盗者从窗进入。由于这种窗型结合了平开和下悬两种操纵,采用这种窗型选用胶条口型留意以下几点:    


1.室内选全封锁口型胶条压缩量不宜过大,1∽2mm就可以了,胶条的壁厚在0.8∽0.9mm为宜,太厚的口型或压缩量过大的口型轻易造成锁闭难题,甚至不能锁闭。   


2.室内胶条推荐选用非封锁口型的胶条,压缩量2∽3mm都可以。条件是胶条的壁厚1∽1.3mm为宜。    


3.室外胶条如框扇间距小于2.5mm,推荐选用非封锁口型的胶条压缩量量0.5∽1mm即可。    


三、隔热断桥铝合金平开窗中胶条口型的选用    


隔热断桥的原理是在铝型材中间穿人隔热条,将铝型材断开形成断桥。有效阻止热量的传导。这种窗型多采中空玻璃。除采用内外框双道密封外,中间加了一道等压胶条密封,这种窗型可以说是当前密封效果最好的窗型。可组装成平开下悬窗或普通铝合金平开窗,这种窗型内外框两层密封选用胶条口型可参照平开下悬窗,但等压胶条的选用必需留意以下几点:    


1.等压胶条是带隔热断桥复合窗密封好坏的枢纽,因为柜窗扇密封胶条具有一定压缩量,铝合金门窗闭合时已经需要一定的闭协力。若片面要求等压胶条的过盈配合量,就会存在关窗费力的现象;因此,等压教条的配合在铝合金门窗闭合时,B部门到稍有变形即可,B部份过盈配合量1∽2mm。且在选用五金件时,合页厚度应和厂家设计一致,    否则轻易导致等压胶条密封的密封失败或窗扇无法闭合。    


2.这种窗型因为型材型腔较大,又采用中空玻璃,自重较大,安装好后,假如五金件(合页、滑撑)质量不外关,极易产生窗扇非合页、非滑撑一侧下沉,即常说的掉角,所以型材厂设计窗型时A>5mm为宜;C<3∽mm,组装厂应充分考虑窗扇的重量,选用相应的五金件,避免产生掉角现象,窗扇卡在等压胶条顶部,造成窗户不能锁闭。
