Rinro｜Point-supported Curtain Wall Technology Lecture

RINRO(凝龙幕墙咨询）｜点式幕墙技术讲座



    2020年12月23日上午，Rinro(凝龙幕墙咨询)邀请沈阳市恒安公司总工程师赵勋海先生到我司进行点式幕墙技术讲座。主讲人赵勋海先生是点支式幕墙专家和索结构专家，在点支式幕墙系统领域的项目应用方面有着丰富成熟的经验。凝龙广州总部公司设计部部分同事参加了此次讲座，贵州分公司及东莞分公司的同事则在线上观看了视频直播。
On the morning of December 23, 2020, Rinro invited Mr. Zhao Xunhai, the chief engineer of Shenyang Hengan Company, to our company for a point-type curtain wall technology lecture. The speaker, Mr. Zhao Xunhai, is a point-supported curtain wall expert and cable structure expert. He has rich and mature experience in project application in the field of point-supported curtain wall systems. Some colleagues from the Design Department of Rinro Guangzhou Headquarters attended the lecture, while colleagues from Guizhou Branch and Dongguan Branch watched the live video online.
    此次讲座中，赵勋海先生重点围绕点式幕墙进行了详细解说，包括钢结构、肋玻璃、拉杆、拉索、组合结构等幕墙构件，以理论结合案例，深入浅出，将专业问题直白化。并且深刻探讨了结构安全、计算方法、材料的优化、材料的选用、合理的降低工程造价、施工方法、测试方法等重点问题。参会的同事认真听讲、用心记录，并与赵勋海先生积极交流沟通，让每一次学习机会都能使自己有所收获，对今后的工作有所帮助。
In this lecture, Mr. Zhao Xunhai focused on the point-supported curtain wall and gave a detailed explanation, including steel structure, glass fin, tie rods, cables, composite structures and other curtain wall components. Combining theory with cases, explaining the problems in a simple way and straightening professional problems. It also deeply discussed key issues such as structural safety, calculation methods, material optimization, material selection, reasonable reduction of project costs, construction methods, and testing methods. The participating colleagues carefully listened to the lectures, recorded carefully, and actively communicated with Mr. Zhao Xunhai, so that every learning opportunity can make them gain and help their future work.
    特别是高通透，广视野玻璃幕墙的逐渐广泛运用的案例让人耳目一新，开拓了大家的设计思路；通过拉索、钢板、玻璃肋的大跨度立柱的运用，极大地提升外立面效果。
In particular, the case of the gradual and widespread use of high-transparent, wide-view glass curtain walls is refreshing and opens up everyone's design ideas; the use of long-span columns with cables, steel plates, and glass fin greatly enhances the effect of the facade.

 
    薄壁钢立柱可以让幕墙龙骨显得更加纤细，降低幕墙龙骨对视野的影响。
Thin-walled steel columns can make the curtain wall keel appear more slender and reduce the impact of the curtain wall keel on the field of vision.

    大跨度玻璃肋支承结构最受建筑师的青睐，看重的是其通透性，特别是SGP胶片和超白玻璃面板与超白玻璃肋板所具有的通透性，对玻璃肋支承结构的推广更有推波助澜的作用。而不锈钢钢板肋以其均匀的质感和令人信赖的安全感也受到建筑师的青睐。
The long-span glass fin support structure is most favored by architects. The most important thing is its permeability, especially the permeability of SGP film and ultra-white glass panels and ultra-white glass fin, which is the promotion of the glass fin support structure It is even more helpful. The stainless steel ribs are also favored by architects for their uniform texture and trustworthy sense of security.
    大跨度不锈钢钢板肋支承结构的造价远低于大跨度玻璃肋支承结构。如15米高的肋支承结构，采用玻璃肋支承，其肋宽度为700mm，玻璃肋厚度为19mm+2.28SGP+19mm+2.28SGP+19mm夹胶钢化玻璃，按照等强原理，采用不锈钢钢板肋支承，其肋宽度为450mm，肋厚度为36mm。前者的造价至少30万元，两段玻璃肋的拼接价格也要15万元以上，后者的造价只有7万元左右。
The cost of a large-span stainless steel steel plate rib supporting structure is much lower than that of a large-span glass fin supporting structure. For example, the 15-meter-high rib support structure adopts glass fin support, the rib width is 700mm, and the glass fin thickness is 19mm+2.28SGP+19mm+2.28SGP+19mm laminated tempered glass. According to the principle of equal strength, stainless steel steel plate rib support is used. , The rib width is 450mm, and the rib thickness is 36mm. The cost of the former is at least 300,000 yuan, the splicing price of the two glass fin is also more than 150,000 yuan, and the cost of the latter is only about 70,000 yuan.
    通过巧妙的设计，实现将以前臃肿的龙骨调整为外立面竖向线性的外观效果。
Through the ingenious design, the previously bloated keel is adjusted to the vertical linear appearance of the facade.
特别是通过借鉴石材背栓的设计理念，将背栓技术大胆运用于玻璃中。对于中空玻璃，应考虑玻璃打孔，使用时漏气的问题。我们采取双道密封。第一道采用防渗垫片；第二道是在玻璃孔与驳接头扣体间一半厚度采用垫圈，另一半厚度采用密封胶密封，防止漏气。另外在后压盖的后面又加了一个锁片，保证驳接头在使用过程中牢固的安装在玻璃上，不会产生松动漏气。在加工好的玻璃合片前，先将驳接头扣体、防渗垫片和垫圈安装在玻璃孔上,打上密封胶,再放入垫片,拧上后盖，拧紧锁紧片。玻璃合片后，驳接头固定在玻璃孔上。为防止在运输和周转过程中,驳接头突出玻璃部分与玻璃相磕碰造成损坏，在驳接头后盖处加了一个运输保护盖，同时要求运输过程中，玻璃间使用10mm垫块隔离,保证玻璃的运输安全。
Especially by drawing on the design concept of back bolt dry hanging stone , the back bolt technology is boldly applied to glass. For insulating glass, consider the problem of glass perforation and air leakage during use. We adopt double sealing. The first is to use impermeable gaskets; the second is to use gaskets for half of the thickness between the glass hole and the buckle body of the barge, and sealant for the other half to prevent air leakage. In addition, a lock piece is added behind the rear gland to ensure that the joint is firmly installed on the glass during use, and no loose air leakage occurs. Before processing the glass sheet, install the joint buckle body, the anti-seepage gasket and the gasket on the glass hole, apply the sealant, and then put in the gasket, screw on the back cover, and tighten the locking piece. After the glass is combined, the joint is fixed on the glass hole. In order to prevent damage caused by collision between the protruding glass part of the joint and the glass during transportation and turnover, a transportation protection cover is added to the back cover of the joint. At the same time, it is required that the glass be separated by a 10mm spacer during the transportation process to ensure the glass safe transportation.

    支承结构的简洁和轻巧改变传统幕墙的结构设计思路。
The simplicity and lightness of the supporting structure change the structural design ideas of the traditional curtain wall.
