對于樓承板如何配鋼筋？這個問題，我們這裏跟大家來詳細解說一下。關于樓承板的配筋計算，我們分兩個問題來解釋，一個是上部鋼筋(包括負彎矩鋼筋)的問題，一個是下部受力鋼筋的問題。上部鋼筋，也叫分布鋼筋、溫度鋼筋，起的作用主要是抵抗四溫度變化和混凝土收縮在垂直于板跨方向所産生的拉應力。通常鋼筋直徑不應小于6mm，間距不大于250mm。而壓型鋼板樓板的上部鋼筋計算方法和普通混凝土樓板相同，按照此方式計算即可。

上部钢筋还包括负弯矩钢筋，它的作用是为了避免板受力后，在支座上部出现裂缝，通常是在这些部们上部配置受拉钢筋，这种钢筋称为负筋。尤其在压型钢板连续跨铺设时，或者在梁的支座处会产生负弯矩，而计算是根据荷载计算支座处的负弯矩而配置相应的钢筋，其直径不应小于8mm，间距不应大于200mm。

下部钢筋，主要是承受正弯矩，根据压型钢板的类型可以按照组合楼板和非组合楼板两个方面来考虑。非组合楼板，压型钢板主要起模板作用，所以，起到承担受力作用的主要是正弯矩钢筋，所以在计算时，按照普通混凝土楼板一样计算，由于钢筋是在布置在压型钢板的板肋中，所以要注意压型钢板板肋的间距，按照板肋的间距来布置受力钢筋。

组合楼板，压型钢板不仅仅起模板的作用，同时也可以代替板底受力钢筋，所以可以根据荷载及跨距情况，可不另配置受力钢筋。而压型钢板主要选用的是闭口压型钢板，正常使用阶段压型钢板的配筋计算，主要是把压型钢板的用钢量折算成钢筋的用量，计算是否满足抗弯要求。

而另一个方面，在火灾情况下，仅仅考虑压型钢板的有效使用部分的用钢量是否满足火灾时的抗弯要求。如果均能够满足，则无须配置钢筋，如果仅仅在使用阶段满足，而火灾阶段不满足，则需配置耐火钢筋。无论是上部钢筋还是下部钢筋均需考虑楼板的保护层厚度，下部钢筋尤其不允许直接放置在压型钢板上面。以上是个人关于楼承板的配筋计算的一些看法。

樓承板是新一代**建築材料。不管是什麽型號的樓承板，在鋪設施工過程中應該滿足配筋要求：

1、樓承板是各向異性版，判斷是單向板還是雙向板要根據各向異性系數，根據各向異性系數計算有效(換算)邊長，按有效邊長的比判斷是單向板還是雙向板。

2、判定爲雙向板，垂直肋方向配筋配在波峰上，順肋方向配在波谷處，但應注意應有不小于20mm的保護層，該保護層主要是保證鋼筋的粘結力。抗力計算則是垂直肋方向爲肋以上混凝土厚度作爲板厚，順肋方向則從波谷算起，即組合樓板厚度爲板厚。

3、延順肋方向，壓型鋼板(將壓型鋼板換算成鋼筋)如能滿足正截面承載力要求，且滿足剪切粘結承載力要求，可以不配順肋方向的鋼筋。特別注意應計算剪切粘結承載力，組合樓板一般是被剪切粘結控制的。《高鋼規》沒有剪切粘結計算，這是疏忽。

4、如果按雙向板計算，波峰處的鋼筋必須配置，壓型鋼板在垂直肋的方向沒有任何作用。

5、組合樓板絕大多數都是單向板，*特別的，比如角部可能是雙向板，因爲有斜梁一般跨度很小，不計算按其他部位同樣配置基本可以滿足。

6、板頂的分布筋是必須滿足GB50010規定的。

7、順肋方向在梁支座處，是連續還是鉸接，不取決于壓型鋼板，而取決于負彎矩鋼筋，壓型鋼板受壓忽略不計。垂直肋方向一般認爲是鉸接，但應配置抗裂構造筋。

8、樓承板並不要求栓釘按組合梁設計，但必須有一定的構造栓釘以保證板與梁的整體性。

9、如果是設計組合梁，一般次梁按組合梁計算，主梁(框架梁)不宜按組合梁計算承載力，因爲框架梁承擔反複荷載，組合梁沒有抗震試驗報告--這一點被規範忽略了，GB50017與GB50010不同，GB50017沒有抗震的內容。主梁在使用荷載下撓度是可以按組合梁驗算(如果滿足組合梁要求)。

‘She is utterly miserable,’ said Charles. ‘It{325} couldn’t be otherwise, could it? And you are miserable too, sir. I am—I am awfully sorry for you both. But I suppose that has got to be. Norah could do nothing else than what she has done.’ I covered it fiercely and sunk my brow upon it. And thereupon the wave of folly drew back, and on the bared sands of recollection I saw, like drowned things, my mother's face, and Gholson's and the General's, and Major Harper's, and Ned Ferry's, and Camille's. Each in turn brought its separate and peculiar pang; and among those that came a second time and with a crueler pang than before was Camille's. "Yes, I've heard it; he is a very daring man; what of it?" "That is quite easy. I have a latchkey in my waistcoat pocket. You have only to go and get the papers, and nobody will be any the wiser. I felt quite sure you would do this thing for me." "Where is my brother?" René repeated doggedly. 49 I did not feel very comfortable after what had happened to those soldiers who lost their lives so cruelly sudden, or in any case had been seriously wounded, while the officers took little notice of them. But it was desirable to behave as discreetly as possible, and so to get a permit to Maastricht. But the German troops had ample provisions for themselves, and as an officer noticed that I went all over the town to find some food in one of the58 restaurants, he offered me, the "friendly" Netherlander, something to eat at the Guard House. This I declined, however, for I could not have enjoyed bread taken from the starving population. To the objection that his suspensive attitude would render action impossible, Arcesilaus replied that any mental representation was sufficient to set the will in motion; and that, in choosing between different courses, probability was the most rational means of determination. But the task of reducing probable evidence to a system was reserved for a still abler dialectician, who did not appear on the scene until a century after his time. Arcesilaus is commonly called the founder of the Middle, Carneades the founder of the New Academy. The distinction is, however, purely nominal. Carneades founded nothing. His principles were identical with those of his predecessor; and his claim to be considered the greatest of the Greek sceptics is due to his having given those principles a wider application and a more systematic development. The Stoics regarded it as a special dispensation of providence149 that Chrysippus, the organising genius of their school, should have come between its two most formidable opponents, being thus placed in a position to answer the objections of the one and to refute by anticipation those of the other.232 It might seem to less prejudiced observers that the thinker whose cause benefited most by this arrangement was Carneades. Parodying a well-known iambic, he used to say: that before. A palankin, hung with heavy red curtains, went by very quickly, borne by five men. They chanted a sort of double-quick march, marking the time with a plaintive sigh and a slight bend of the knees, which gave their pace the appearance of a dance, the litter swaying very gently. 58 From the Picture in the National Gallery of British Art. A generous cupful was set aside for Capt. McGillicuddy, which his servant received with gratitude and glowing reports of the good the former supply had done him. "Is this a place for sleeping?" "I dunno. Somewheres between here and Canada. May she rot there lik a sheep on its back, and her man too. Now say 'poor Rose.'" He drove through Peasmarsh and turned into the Totease lane. The fields on both sides of it were his now. He sniffed delightedly the savour of their sun-baked earth, of the crumpling leaves in their hedges,[Pg 448] of the roots, round and portly, that they nourished in their soil—and the west wind brought him the scent of the gorse on Boarzell, very faintly, for now only the thickets of the top were left. "And this is the first fruits of liberty," muttered the monk—"but no good can be had unalloyed with evil." HoME 正在播放福利周晓琳 ENTER NUMBET 0014www.haolihaosan.com.cn
