建筑规划相关知识：承受活荷载的屋面玻璃活荷载设计要求

1、.1、对上人的屋面玻璃，应按下列最不利情况，分别计算：1）玻璃板中心点直径为150mm的区域内，应能承受垂直于玻璃为1.8kN的活荷载。2）居住建筑，应能承受1.5kPa的均布活荷载；对非居住建筑，应能承受3kPa的均布活荷载。2、对不上人的屋面玻璃，设计应符合下列规定：1）与水平面夹角小于30°的屋面玻璃，在玻璃板中心点直径为150mm的区域内，应能承受垂直于玻璃为1.1kN的活荷载。2）与水平面夹角不小于30′的屋面玻璃，在玻璃板中心直径为150mm的区域内，应能承受垂直于玻璃为0.5kN的活荷载。 广州陶粒厂 广东陶粒厂 编辑:ejdnchh.;summer of m

2、asonry construction, brick requires sufficient moist. 8.6.2.6 you must take the following measures to concrete construction in summer high temperature impact on concrete a. hardening speed up, vibrating difficulties reduced bleeding, fast drying, easy to crack (plastic), high early strength, fast ea

3、rly hydration heat, less cooling, temperature increases rapidly, due to temperature difference cracks. B. pouring daytime high temperatures, due to the high temperature effect of concrete strength, stability, in varying degrees, on mixing processes, perfusion vibration and moisture conservation, eff

4、ective measures should be taken. 2) main measures taken by a. temperature control the water temperature in your standard mix proportion of concrete 2 degrees, the concrete temperature 0.5 degrees. B. with the controlled addition of retarder agent can reduce the effects of concrete under high tempera

5、ture, but make some performance degradation of concrete, so when you are using additives must be implemented upon approval by the supervising engineer. C. time control suitable for work at night, should seek to reduce the mixing time and shipping time at high temperatures. D. strengthen the conservation and high temperatures after pouring in the early days of continuous water conservation to prevent surface drying and covering thin-film wet grass bag to make it moist State in 24 hours. 8.6.3 8.6.3.1 winter construction measures in winter construction prepara
