建筑規(guī)劃相關(guān)知識：承受活荷載的屋面玻璃活荷載設(shè)計要求

1、.1、對上人的屋面玻璃，應(yīng)按下列最不利情況，分別計算：1）玻璃板中心點直徑為150mm的區(qū)域內(nèi)，應(yīng)能承受垂直于玻璃為1.8kN的活荷載。2）居住建筑，應(yīng)能承受1.5kPa的均布活荷載；對非居住建筑，應(yīng)能承受3kPa的均布活荷載。2、對不上人的屋面玻璃，設(shè)計應(yīng)符合下列規(guī)定：1）與水平面夾角小于30°的屋面玻璃，在玻璃板中心點直徑為150mm的區(qū)域內(nèi)，應(yīng)能承受垂直于玻璃為1.1kN的活荷載。2）與水平面夾角不小于30′的屋面玻璃，在玻璃板中心直徑為150mm的區(qū)域內(nèi)，應(yīng)能承受垂直于玻璃為0.5kN的活荷載。 廣州陶粒廠 廣東陶粒廠 編輯: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
