钢筋桁架混凝土组合楼承板施工技术研究

Research on Construction Technology of Reinforced Truss Concrete Composite Floor Slab

文中以福建省某高层办公楼为例,通过有限元模拟和现场试验对其承载能力、抗裂性能及耐久性进行评估。结果表明,钢筋桁架混凝土组合楼承板在最大设计荷载10.5 kN/m^(2)下的最大挠度为4.2 mm,远小于规范限值24 mm;实际工程应用中,该技术缩短工期20%,节省模板用量50%,降低总施工成本约15%。钢筋桁架混凝土组合楼承板在高层建筑、工业厂房及公共建筑等领域具有广泛的应用前景。

Taking a high-rise office building in Fujian Province as an example,the load bearing capacity,crack resistance and durability of the building were evaluated by finite element simulation and field test.The results show that the maximum deflection of reinforced truss concrete composite floor slab under the maximum design load of 10.5kN/m~w is 4.2mm,which is far less than the standard limit of 24mm.In practical engineering application,the technology shortens the construction period by 20%,saves the template consumption by 50%,and reduces the total construction cost by about 15%.Reinforced truss concrete composite floor slab has a wide application prospect in high-rise buildings,industrial plants and public buildings.
