摘要:
为了提高拉索玻璃幕墙连接件的抗倾覆性能,分析了导致连接件倾覆的主要因素.提出了驳接爪式和夹板式连接件的统一力学模型,探讨了拉索截面积、预张力、跨度、索间距、玻璃与竖索间距、握裹长度、玻璃边长等参数对连接件抗倾覆的影响.研究结果表明:竖索截面积对连接件抗倾覆性能的影响大于横索截面积,竖索预张力的影响大于横索预张力,竖索跨度的影响大于横索跨度,竖索握裹长度的影响大于横索握裹长度;倾角与竖索截面积呈幂函数关系;当索网跨度为12.6 m、玻璃为正方形时,倾角与玻璃边长呈指数关系;索网最下排跨中连接件的倾角最大;增加竖索的截面积、预张力、握裹长度,减小竖索的跨度和玻璃边长有利于改善连接件的抗倾覆性能.
Abstract:
To improve the overturning resistance of connectors in a cable glass curtain wall, the main factors making connector overturning were discussed. A uniform mechanical model for both the spider and the glass-clamp connectors was proposed. The influences of the parameters, such as the cable sectional area, the pretension, the span, the space between the horizontal cable and the vertical cable, the space between the glass and the vertical cable,the bond length, the glass length and so on, on the overturning resistance were studied. The results show that the effect of the sectional area of the vertical cable on the overturning resistance of the connectors is greater than that of the sectional area of the horizontal cable. The effect of the pretension of the vertical cable is greater than that of the horizontal cable. The span of the vertical cable exhibits greater impact than that of the horizontal cable. The effect of the bond length of the vertical cable is greater than that of the horizontal cable. There is a power function relationship between the overturning angle and the sectional area of the vertical cable. When the span of the cable net is 12.6 m and the glass is square, an exponential relationship exists between the overturning angle and the glass length. The overturning angle of the connectors at the mid-span of the lowest row is the maximum. The overturning resistance of the connectors in the cable glass curtain wall can be improved by increasing the section area of the vertical cable, the pretension of the vertical cable as well as the bond length of the vertical cable and decreasing the span of the vertical cable and the glass length.
