Lesson Six—All Glass /Point-Fixing Curtain Wall Ⅰ Introduction（技术简介） All glass and point-fixing glass curtain wall came into being① with technology improvement and product diversity of glass and stainless steel. Because they are transparent, their outside look is much better than stick and unitized curtain wall. Ⅱ Conversation（会话） O—Owner; C—Contractor O: Could you please tell me how many kinds of glass rib system? C: Normally four kinds, namely rear-support, joint-mounted, surface-levelled and surface-projected. O: Could you give me a simple introduction on how the rib is stuck to the glass within one storey? How about within multi-storeys? C: When install glass rib system, we used to clamp the glass and the rib with rabbet and keep the collision chock between glass and rabbet bottom. If the storey is too high, we should further adopt Top Hanging Method. If the installation is within multi-storeys, there are two ways, namely levelling-wall and projecting-wall. O: Could you put in detail④ Top Hanging Method that you mentioned just now? C: Top Hanging means hanging the glass with special clamp. Furthermore, we choose Top Hanging Method when the storey is relatively high and the glass is relatively thick. O: The expansion joint is held between glass and rabbet, so I want to know how elaborate on⑤ how to do with the joint? C: The joint between glass and rabbet can be filled with dry or wet material or the mixture of dry and wet material. However, the weather side may be preferably filled with wet material. That’s to say we adopt structural adhesive for fixing and sealing sealant for seal, in order to improve air resistance and water resistance property. O: How is the glass panel connected with the rib? C: We connect the glass panel and the rib with sealing sealant, namely “glass rib system”; another one is to fix the glass panel with rib and spider on it, namely “glass rib point-fixing system”. O: Let’s proceed to⑦ point fixing system. How many kinds? C: Mainly four kinds: 1. Glass rib point-fixing system; 2. Rod point-fixing system; 3. Cable point-fixing system; 4. Steel structure point-fixing system. O: I have a question, if all the three kinds of point-fixing curtain wall, you mentioned above, should be connected with construction main structure by welding. C: That’s a good question. Welding method is not suitable for⑧ cable & rod point-fixing curtain wall. Instead, we use S.S. clamp to connect with reinforced-concrete main structure. But the calculation of this method is difficult. O: What is the requirement of glass thickness when using different fasteners? C: No less than 6 mm and no less than 8 mm respectively for pan head and counter-sunk head. O: What do you mean by pan head and counter-sunk head? C: As you can see, pan head and counter-sunk head are divided by the exposition form (fastener) of spiders. O: Do you have any beautiful and scientific connecting method for point-fixing curtain wall? C: Yes. Unlike pan head and counter-sunk head, the newly born Back-Bolt Method can make the outlook more beautiful and is not apt to⑨ leakage, meanwhile eliminating “Cold Bridge Effect”. O: Finally, Let’s end with the classification of point-fixing all glass curtain wall. C: There are H type, X type and I type according to the shape. There are pan head type and counter-sunk head type according to⑩ outer surface shape. There are fixing type, ball hinge type and vertical spring type according to adjustment method. O: Thank you for your substantial explanation. C: You are welcome. Don’t hesitate to call me when you have questions.
