摘要
混凝土转换梁采用叠合梁的施工方法,由于先浇混凝土对后浇混凝土的约束,使叠合面产生剪应力。对叠合面剪应力进行分析计算,采用插筋的方法增强叠合面的抗剪能力,为混凝土转换梁叠合面施工提供依据,该方法也适用于大体积混凝土厚板叠合面的状况。
The concrete transfer beam applies laminated beam in construction, and because of the constraint of earlier pouring concrete to later pouring concrete, shear stress is induced in lamination. The calculation method for shear stress of lamination is introduced in this paper, and inserting steel bars method is adopted to strengthen shear resistance capacity. This method is basis for construction of lamination of concrete transfer beam, and it is also suitable for thick plate lamination of massive concrete.
