摘 要:在钢纤维混凝土复合单向板研究的基础上,采用不同的拼接形式,将单向板连接成双向板。通过对比不同拼缝拼接板的力学性能发现,插入式锚固的延性最好;采用两倍受力主筋间距的螺栓连接方式的刚度最大;搭接焊的承载力最大。插入式锚固、螺栓锚固及搭接焊锚固均能满足连接要求,螺栓锚固的强度和刚度最大。
Abstract: Based on the study results of steel fiber reinforced concrete composite one-way slab, the one-way slab can be connected to a two-way slab by using different splicing forms. Comparing the mechanical properties of different splicing slabs, it's found that the ductility of the inserting anchorage is the best, and the rigidity of the bolt connection with the spacing of two multiple main tendons is the greatest, and the bearing capacity of lap welding is the best. It can be seen that inserting anchorage, bolt anchorage and lap welding anchorage can meet the requirements of connection. The bolt anchorage has the maximum strength and stiffnesss.
