1、敞開窗所用鋁合金資料，依照幕墻行業(yè)標(biāo)準(zhǔn)工藝及結(jié)構(gòu)安全性要求，一套完好的敞開窗邊框和窗扇是應(yīng)該選用組角角碼在工廠拼裝成為一體的單元結(jié)構(gòu)，在實(shí)踐的項(xiàng)目查看處理問題的時(shí)分，確常常看到一些項(xiàng)目的敞開邊框沒有采納組角出產(chǎn)工藝，而是將邊框的資料的四條邊料作為散料運(yùn)輸?shù)焦こ态F(xiàn)場，通過現(xiàn)場非別散裝完結(jié)敞開邊框的裝置，只要敞開窗的鋁合金扇框是選用車間組角的工藝出產(chǎn)。由此形成項(xiàng)目敞開邊框的轉(zhuǎn)角常常出現(xiàn)錯(cuò)位、漏光(通明)、邊框的內(nèi)徑尺度發(fā)作改動(dòng)等情況，一起敞開窗的鋁合金扇框與邊框之間的組合尺度發(fā)作改動(dòng)、敞開的相關(guān)不銹鋼五金的受力情況發(fā)作改動(dòng)、封閉鎖點(diǎn)的間隙改動(dòng)帶來固定方法的改動(dòng)等，這一系列的改動(dòng)均有可能形成敞開窗扇的全體掉落。

2、幕墻敞開窗所用敞開五金，一般所挑選的敞開五金有兩個(gè)部位，首先是敞開的承重功用不銹鋼鉸鏈結(jié)構(gòu)，其次是具有安全封閉功用的鎖結(jié)構(gòu)，這兩個(gè)部位的結(jié)構(gòu)假如有一個(gè)部位的收購不妥，都會(huì)斷定該敞開窗扇結(jié)構(gòu)有問題。

　?、龠x材方面：不銹鋼敞開鉸鏈應(yīng)該是不銹鋼原料，假如選材時(shí)沒有細(xì)心查看檢驗(yàn)，或許所供資料是真的不銹鋼原料、鉸鏈結(jié)構(gòu)有瑕疵(不細(xì)心看不到的裂紋)，會(huì)導(dǎo)致項(xiàng)目生命周期內(nèi)鉸鏈銹蝕、裂紋逐漸顯著等;

　　②安全方面：敞開窗鎖點(diǎn)應(yīng)該是多點(diǎn)結(jié)構(gòu)(最少應(yīng)該有2點(diǎn))，有些項(xiàng)目到當(dāng)今還在選用最一般的單點(diǎn)結(jié)構(gòu)(俗稱七字執(zhí)手)，這種結(jié)構(gòu)的原料基本上都是選用模具鑄造鋁材，這種原料結(jié)構(gòu)只要一個(gè)單爪，往往會(huì)發(fā)作因?yàn)榻邮芡饬Φ墓τ靡约把b置不完善形成掉落失掉安全功用;乃至有的項(xiàng)目在敞開方法上選用的合頁懸掛結(jié)構(gòu)，這種結(jié)構(gòu)的原料基本上都是選用模具鑄造鋁材，資料鑄造的密實(shí)度不行或沒有通過嚴(yán)厲結(jié)構(gòu)受力核算，在幕墻的運(yùn)用生命周期內(nèi)因?yàn)楹享摰臄嗔训?，都有可能形成敞開窗扇全體掉落。

3、當(dāng)一個(gè)項(xiàng)目的幕墻敞開窗扇翻開的時(shí)分，時(shí)至今日咱們或許會(huì)注意到敞開窗扇的底部有多少?zèng)]有托板，這個(gè)問題按說是不應(yīng)該發(fā)作的，從我國《玻璃幕墻工程技術(shù)規(guī)范》JGJ102發(fā)布那天就有了應(yīng)該設(shè)置托板的嚴(yán)厲要求，所以在這里也就不多說了，當(dāng)然了有的敞開窗扇玻璃底部的確設(shè)置了托板結(jié)構(gòu)，可是托板的結(jié)構(gòu)懸挑長度沒有拖住最外側(cè)的那一片玻璃，仍然是這一塊敞開扇的玻璃結(jié)構(gòu)永遠(yuǎn)處于不安全隨時(shí)可能掉落的狀態(tài)。

　　4、有的玻璃幕墻項(xiàng)目，在投標(biāo)進(jìn)程由參謀單位以及施工單位施工圖深化，都?xì)w納選用了敞開扇玻璃周邊設(shè)置封邊的安全措施，可是因?yàn)榻Y(jié)構(gòu)考慮不周、缺少實(shí)踐車間出產(chǎn)的經(jīng)歷，形成該安全封邊結(jié)構(gòu)無法完成真實(shí)的安全，因?yàn)橹锌詹ＡП旧淼暮掀媒Y(jié)構(gòu)密封膠與鋁合金粘接用結(jié)構(gòu)不在同一平面直線內(nèi)，由此帶來的玻璃會(huì)發(fā)生掉落的安全危險(xiǎn)。

　　5、有的項(xiàng)目效果圖的確十分漂亮，獨(dú)自從外表是看不出有安全危險(xiǎn)的存在，當(dāng)翻開施工進(jìn)程圖紙翻開一看，整個(gè)項(xiàng)目的玻璃幕墻不光固定玻璃選用大小片結(jié)構(gòu)、敞開窗扇玻璃也選用大小片結(jié)構(gòu)，關(guān)于這種結(jié)構(gòu)，隨時(shí)都有可能發(fā)作玻璃掉落的危險(xiǎn)。

　　6、有的項(xiàng)目或許是不知道怎么處理敞開窗扇的結(jié)構(gòu)安全問題，爽性就不加思考的直接將玻璃板塊粘接到鋁合金敞開扇框上，在明知道這種結(jié)構(gòu)是不安全的時(shí)分而為之，乃至有些項(xiàng)目假如依照施工圖的表達(dá)，所選用的敞開邊框資料是裝置不了的，并且也無法滿意長時(shí)間的耐候密封功用，也就是說因?yàn)榭紤]不周帶來了不光安全存在問題，就連功用性也會(huì)受到影響。

1, the aluminum alloy materials used for the open window, according to the standard technology and structural safety requirements of the curtain wall industry, a complete set of open window frame and window sash should be used as a unit structure of assembling the corner code in the factory. When the practical project looks at the problem, the open border of some projects is often seen. The production process is adopted, but the four sides of the material on the border are transported to the site of the project as bulk material. As a result, the angles of the open frame are often misplaced, leaked (Tong Ming), and changes in the internal diameter of the frame, such as changes in the combination scale between the open window and the frame, the change of the open related stainless steel hardware, the change of the closed lock gap and the fixing of the gap. Changes in the method and so on, this series of changes may form the whole window sash falling.

2, the curtain wall open window open hardware, generally selected open hardware has two parts, first is the open bearing function of stainless steel hinge structure, followed by a safe and closed function of the lock structure, the two parts of the structure if one part of the purchase is not appropriate, it will be determined that the open window fan structure has problems.

Material selection: stainless steel hinge should be a stainless steel material, if the material is not carefully checked, perhaps the material is true stainless steel raw material, hinges structure is defective (not carefully seen in the crack), will lead to the project life cycle hinges corrosion, cracks gradually manifest and so on;

Safety: open window lock point should be a multi point structure (at least 2 points), some projects to today still choose the most common single point structure (commonly known as seven words), the raw material of this structure is basically used die casting aluminum, this material structure as long as a single claw, often happens because of the external force. The use of the equipment is not perfect and the safety function of falling and losing is formed; and even the hinge suspension structure of some projects is selected in the open method. The material of this structure is basically used to die casting aluminum. The breakage of pages can all cause the fall of open window sashes.

3. When the curtain wall of a project opens open, we may notice today that there is no board at the bottom of the open window fan. This problem is not supposed to occur. From the day of the release of the technical specification for glass curtain Engineering in China, the stern requirements should be set up on the day of JGJ102. There is not much to say here, but of course some of the open window glasses have a plate structure, but the length of the bracket has not dragged the most outside glass. It is still the state that the glass structure of this open fan is always in a state of insecurity and may fall at any time.

4, some glass curtain wall projects, in the tender process from the staff of the staff and the construction unit, the construction drawing deepened, all of which have selected the safety measures to set up the edge of the open fan glass, but because the structure is not considered and the experience of the production of the workshop is short of practice, the security seal structure can not complete the real safety. The structural sealant of the insulating glass itself is bonded to the aluminum alloy, and the structure is not in the same plane. The resulting glass will be in danger of falling.

5, some project effect map is really very beautiful, alone from the appearance is not able to see the existence of safety danger, when the construction process drawing open a look, the whole project glass curtain wall is not only fixed glass structure, open window glass also selected size piece structure, about this structure, at any time may be sent. The danger of falling glass.

6. Some projects may not know how to deal with the structural safety of the open window fan, and the glass plate is directly attached to the open fan frame of the aluminum alloy without thinking. The material is not the device, and can not satisfy the long time weather sealing function, that is to say that because of bad consideration caused by not light safety problems, even the utility will be affected.
