钢筋混凝土蜂巢芯空腹楼盖研究与力学分析 钢筋混凝土蜂巢芯空腹楼盖研究与力学分析 摘 要 现浇钢筋混凝土蜂巢芯空心板楼盖是一种新型的楼盖体系，它自重轻，跨 度大，它己经在一些工程项目上投入使用，取得了良好的经济效益和社会效益。 它可以提供较灵活的空间，且经济指标较高，有着广泛的应用前景，但人们对 其认识还不够。此类楼盖是在现浇混凝土楼板中布置一定数量的预制永久性高 强薄壁箱体模盒而形成的新型空心楼盖体系。由于蜂巢芯空心楼盖是出现不久 的新技术，外界关于该技术的研究较少，本文通过结合具体工程，对该技术进 行了进一步研究。论文的主要研究内容如下：首先，简单介绍一下蜂巢芯空心楼 盖；再次，介绍了蜂巢芯楼盖的施工工艺。该项技术施工的重点和难点是解决 蜂巢芯在浇筑时的上浮和位移以及浇筑时蜂巢芯和混凝土之间的密实问题。文 章通过具体工程的施工经验，对上述问题给出了一定的施工方案和解决措施。 最后采用解析方法(拟夹层板法)得到四边简支板的弹性解。根据刚度等效的 原则，将蜂巢芯楼盖比拟为实心双向板，运用弹性薄板理论，提出该种楼盖的 内力及变形的求解方法。 关键词：蜂巢芯，拟夹层板法，蜂巢芯空心楼盖，混凝土，建筑技术，施工技术 Study Study and Mechanics Analysis about honey comb core reinforced concrete hollow slab ABSTRACT The honey combed’core hollow floor is a new style of floor．The weight of this floor lS small and the span of this floor is large．the honey combed．COre h0110w floor adapts the demands for the floor system of this age．It has been used in some Proj ects and has gained great social effects and economical profits．This kind of floor system can provide flexible spaces economically，and can be used widelv although the design theories are not mature．This kind of floor system belongs to the hollow reinforced concrete in which a number of prefabricated permanent high strength thin。wall core boxes are laid．At the first，the artile introdudes the hondev core hollow floor slab；Once more，this paper focused on the construction technology of floor slab with comby core，and the key and difficulty of it is to s01ve the problem of core floating in the pouring and displacement，and the densitv b吼ween comby core and concrete issue．Through specific construction proj ect．and resolution measures about above questions．a certain amount of construction are given·At last，the elastic solution of the slab on the simple support is given using simulating sandwich plate method．According to principle of the stif．f．ness are equiValent，honeycombed·core slab was analyzed to solid two．way slab．then the calculate method of the slab’s internal fore and deflection was proposed based on the theory of thin rec
