Description
本发明涉及建筑技术领域,尤其涉及一种局部叠合板连接节点及其施工方法。The invention relates to the field of construction technology, and in particular to a connection node of a partially laminated board and a construction method thereof.
混凝土叠合板是一种将预制混凝土板和现浇层相结合的楼板结构形式,具有施工快速,节省模板等优点。单向叠合板板侧拼接宜采用配置附加钢筋的密拼接缝,而双向板板侧拼接宜采用后浇带式接缝。住宅建筑的楼板绝大部分为双向受力板,传统的叠合板构造不能实现叠合板的双向受力功能。若双向受力叠合板按单向板设计,但由于后浇层的刚度作用,楼板仍先按双向板传力;待接缝位置开裂后,才转变为单向板受力。这样的设计不但用钢量增加、而且使用阶段容易楼板开裂、影响用户使用。若双向受力叠合板按后浇带式接缝,需采用支模施工,并在叠合板下采用顶撑加横梁作用临时的调平措施;导致施工速度慢,施工成本上升。Concrete laminated slab is a kind of floor structure that combines precast concrete slab and cast-in-place layer. It has the advantages of fast construction and saving formwork. The side splicing of one-way laminated slabs should adopt dense splicing seams with additional steel bars, while the side splicing of two-way slabs should adopt post-cast belt joints. Most of the floor slabs of residential buildings are two-way load-bearing slabs, and the traditional laminated board structure cannot realize the two-way load-bearing function of the laminated board. If the two-way force superimposed slab is designed as a one-way slab, but due to the rigidity of the post-cast layer, the floor slab still transmits the force according to the two-way slab first; after the joint position is cracked, the force is changed to the one-way slab. Such a design not only increases the amount of steel used, but also tends to crack the floor during use, which affects users' use. If the two-way force-bearing laminated slab is joined by a post-cast belt type joint, a supporting form shall be used for construction, and temporary leveling measures shall be adopted under the laminated slab for top bracing and beams; resulting in slow construction speed and increased construction costs.
