Slab end slotted hole SP hollow laminated slab-steel beam connecting structure and construction method thereof
The invention provides a slab end slotted hole SP hollow laminated slab-steel beam connecting structure and a construction method thereof. The slab end slotted hole SP hollow laminated slab-steel beam connecting structure is composed of an SP prestressed hollow slab with a slab end core hole slotted hole and a slab top hole, a steel bar net rack, a shearing force connecting piece and a post-pouring concrete layer. The slab end of the prefabricated SP prestressed hollow slab is provided with an elongated slot, the slab top hole is formed, the steel bar net rack is placed in the slot, the shearing force connecting piece is welded to a steel beam, and the slab end elongated slot and core hole are filled when the concrete post-pouring layer is poured. The effective width of slab ribs can be increased by filling the slab end core holes with the concrete, the slab end shear bearing capacity can be improved, the weak part of the slab is reinforced, the longitudinal continuity and integrity of the floor slab can be guaranteed through the steel bar net rack, part of hogging moment can be borne under the vertical load, the midspan deflection of the composite floor system is reduced, the vertical bearing capacity is improved, the steel bar can be used as a longitudinal shear-resistant steel bar of a composite beam and a slab-end shear-resistant steel bar to enhance the slab-end shear-resistant bearing capacity, and a wide application prospect is achieved.
本发明提供了一种板端开槽孔SP空心叠合板‑钢梁连接及其施工方法，由板端芯孔开槽、板顶开孔的SP预应力空心板、钢筋网架、剪力连接件和后浇混凝土层构成，本发明在预制SP预应力空心板板端开长槽、板顶开孔，槽内放置钢筋网架，钢梁上焊接剪力连接件，浇筑混凝土后浇层时填实板端长槽和芯孔。本发明在板端芯孔处填实混凝土可以增加板肋的有效宽度，提高板端抗剪承载力，补强了板的薄弱部位，钢筋网架可保证楼板纵向的连续性和整体性，在竖向荷载下可以承受部分负弯矩，减小组合楼盖的跨中挠度、提高竖向承载力，并可作为组合梁的纵向抗剪钢筋、充当板端剪力筋以增强板端抗剪承载力，具有广阔的应用前景。
