电动开窗器的设计不当的危害有哪些呢?

1、敞开窗所用铝合金资料，依照幕墙行业标准工艺及结构安全性要求，一套完好的敞开窗边框和窗扇是应该选用组角角码在工厂拼装成为一体的单元结构，在实践的项目查看处理问题的时分，确常常看到一些项目的敞开边框没有采纳组角出产工艺，而是将边框的资料的四条边料作为散料运输到工程现场，通过现场非别散装完结敞开边框的装置，只要敞开窗的铝合金扇框是选用车间组角的工艺出产。由此形成项目敞开边框的转角常常出现错位、漏光(通明)、边框的内径尺度发作改动等情况，一起敞开窗的铝合金扇框与边框之间的组合尺度发作改动、敞开的相关不锈钢五金的受力情况发作改动、封闭锁点的间隙改动带来固定方法的改动等，这一系列的改动均有可能形成敞开窗扇的全体掉落。

2、幕墙敞开窗所用敞开五金，一般所挑选的敞开五金有两个部位，首先是敞开的承重功用不锈钢铰链结构，其次是具有安全封闭功用的锁结构，这两个部位的结构假如有一个部位的收购不妥，都会断定该敞开窗扇结构有问题。

　　①选材方面：不锈钢敞开铰链应该是不锈钢原料，假如选材时没有细心查看检验，或许所供资料是真的不锈钢原料、铰链结构有瑕疵(不细心看不到的裂纹)，会导致项目生命周期内铰链锈蚀、裂纹逐渐显着等;

　　②安全方面：敞开窗锁点应该是多点结构(最少应该有2点)，有些项目到当今还在选用最一般的单点结构(俗称七字执手)，这种结构的原料基本上都是选用模具铸造铝材，这种原料结构只要一个单爪，往往会发作因为接受外力的功用以及装置不完善形成掉落失掉安全功用;乃至有的项目在敞开方法上选用的合页悬挂结构，这种结构的原料基本上都是选用模具铸造铝材，资料铸造的密实度不行或没有通过严厉结构受力核算，在幕墙的运用生命周期内因为合页的断裂等，都有可能形成敞开窗扇全体掉落。

3、当一个项目的幕墙敞开窗扇翻开的时分，时至今日咱们或许会注意到敞开窗扇的底部有多少没有托板，这个问题按说是不应该发作的，从我国《玻璃幕墙工程技术规范》JGJ102发布那天就有了应该设置托板的严厉要求，所以在这里也就不多说了，当然了有的敞开窗扇玻璃底部的确设置了托板结构，可是托板的结构悬挑长度没有拖住最外侧的那一片玻璃，仍然是这一块敞开扇的玻璃结构永远处于不安全随时可能掉落的状态。

　　4、有的玻璃幕墙项目，在投标进程由参谋单位以及施工单位施工图深化，都归纳选用了敞开扇玻璃周边设置封边的安全措施，可是因为结构考虑不周、缺少实践车间出产的经历，形成该安全封边结构无法完成真实的安全，因为中空玻璃本身的合片用结构密封胶与铝合金粘接用结构不在同一平面直线内，由此带来的玻璃会发生掉落的安全危险。

　　5、有的项目效果图的确十分漂亮，独自从外表是看不出有安全危险的存在，当翻开施工进程图纸翻开一看，整个项目的玻璃幕墙不光固定玻璃选用大小片结构、敞开窗扇玻璃也选用大小片结构，关于这种结构，随时都有可能发作玻璃掉落的危险。

　　6、有的项目或许是不知道怎么处理敞开窗扇的结构安全问题，爽性就不加思考的直接将玻璃板块粘接到铝合金敞开扇框上，在明知道这种结构是不安全的时分而为之，乃至有些项目假如依照施工图的表达，所选用的敞开边框资料是装置不了的，并且也无法满意长时间的耐候密封功用，也就是说因为考虑不周带来了不光安全存在问题，就连功用性也会受到影响。

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.
