Connecting joint of prestressed hollow slab and concrete beam and connecting method thereof
The invention provides a prestressed hollow slab and concrete beam connecting node and a connecting method thereof.The prestressed hollow slab and concrete beam connecting node comprises a concrete beam and prestressed hollow slabs erected on the two sides of the concrete beam and further comprises a pre-buried supporting piece and a node connecting device; the pre-buried supporting piece comprises a pre-buried bottom plate pre-buried on the concrete beam and L-shaped supporting plates arranged on the two sides of the pre-buried bottom plate, transverse plates of the supporting plates are used for erecting the prestressed hollow slab, a top plate is erected on the tops of vertical plates of the two supporting plates, and the joint connecting device comprises two sets of cross-shaped hinge rod pieces, bottom bolt sleeves, top bolt sleeves and bolts. According to the node connecting device, the mechanical telescopic principle is applied, the cross-shaped hinged rod pieces are utilized to quickly penetrate into the prestressed hollow slab, the supporting nodes at equal intervals in the length direction of the prestressed hollow slab are formed after the cross-shaped hinged rod pieces are unfolded, the supporting strength is greatly improved, adjustment is convenient, the construction period is short, and the construction cost is low. And the situation that a floor slab falls off when an earthquake occurs in a traditional shelving type joint is avoided.
本发明提供一种预应力空心板与混凝土梁的连接节点及其连接方法，包括混凝土梁以及架设在其两侧的预应力空心板，还包括预埋支撑件和节点连接装置，所述预埋支撑件包括预埋在混凝土梁上的预埋底板以及设置在其两侧的L型支撑板，支撑板的横板上用于架设预应力空心板，两个支撑板的竖板顶部架设有顶板，所述节点连接装置包括两组十字铰接杆件、底部螺栓套、顶部螺栓套和螺栓。节点连接装置运用了机械伸缩原理，利用十字铰接杆件快速深入预应力空心板，十字铰接杆件撑开后形成若干沿预应力空心板长度方向等间距的支撑节点，支撑强度大大提升，且调节方便、施工周期短，避免了传统搁置式节点在地震时出现楼板脱落的状况。
