五金门窗的发展旅程

2015-11-10

17世纪末,格窗受到玻璃生产技术的制约,一般都是根据格扇的轮廓相应地镶嵌进小块的玻璃就可以了。所以此时的窗户功能只能是挡风遮雨以及防止盗贼入侵。直到17世纪晚期,随着时代的进步,玻璃工业化的进步,人与自然的关系的变化。人们意识到窗户也应该是纯功能化的—而不是只具有简单的采光、观景、遮蔽风雨的作用。在此期间英国人发明了直棱式竖铰链窗(即平开窗);荷兰人发明了吊窗(即上下提拉窗),吊窗沿垂直方向滑动由一种滑轮装置控制。标志着“门窗五金系统”的诞生。
五金系统在铝合金门窗系统开发中的目标及作用
随着建筑形式及功能要求的不断发展,对门窗幕墙的要求越来越高,而为了满足建筑的要求,五金系统技术在门窗设计中的作用也需要被重新定位。这看起来非常简单,但事实并非如此。这需要精心的规划、引导并投人大量的精力、财力才能达到这样的设计目的。五金系统的开发设计应具有一定的适应性和灵活性。在设计开发过程中应充分考虑“建筑因素”及“人的因素”。使其装饰性、功能性、安全性、便捷性及舒适性均应满足建筑设计的要求。
对于铝合金门窗系统开发设计的最终目标—-种新的门窗形式,只有当设计者头脑中产生了完整清晰的设计概念后,才能产生明确的门窗形式。因此为了实现这个目标,设计者必须将其问题追溯到最初的功能因素,并能在其中找到某些模式。只有理解了我们的目标和设计准则,然后才能进行系统开发。所以门窗的系统开发与门窗五金的选型或开发是紧密相连、相辅相成的。更重要的是门窗的风压变形性、水密性、气密性、保温性、隔声性、内变形性、启闭性、垂直荷载、反复启闭性等都与五金系统有关,五金系统对门窗性能的优劣,起着决定性的作用,正如门窗行业专家李之毅教授所倡导的“五金配件非配角,而是门窗的心脏”。
门窗五金系统的多样化

建筑设计理念的发展和窗户系统技术以及机械和材料工业的进一步发展,建筑五金的范畴也从传统简单的形式向功能性、专用性发展。门窗将更具有生机,节能系统、采光系统、通风系统与门窗的联系将使五金件具有更准确的功能特性,以及与门窗各相关系统良好的适应性。各种各样的五金系统应运而生,如目前市场常见的形式:外平开五金、内平开五金、内开内倒五金、中悬窗五金(垂直悬转)、中悬窗五金(水平旋转)、外悬窗五金、推拉五金、外平推五金、内倾平滑侧移五金、电动五金、智能化电动五金、折叠开启五金、提拉五金、通风换气装置等等。
