Prestressed hollow slab connecting joint structure
The invention relates to the technical field of building structures, and provides a prestressed hollow slab connecting joint structure. The prestressed hollow slab connecting joint structure is characterized in that to-be-connected prestressed hollow slabs are placed on two sides of an upper flange of a steel beam and are good in stress performance, and rubber pads are placed on the lower sides ofthe ends of the prestressed hollow slabs, so that the prestressed hollow slabs are stressed more uniformly, the generated friction force provides lateral support for the prestressed hollow slabs, sothat the stability is improved; the two prestressed hollow slabs are connected through truss ribs, the truss ribs are standardized production parts and can be directly purchased in batches, thus the purchasing cost is reduced, the precision is improved, the diameters of the three longitudinal ribs of each truss rib are large, the truss ribs are in a triangular prism shape and are more stable, theanti-shearing effect is higher, the truss ribs and concrete are combined more tightly after concrete is poured, and integrity is better; and the long circular hole formed by cutting the two circular holes in the prestressed hollow slab in the staggered mode replaces a through long groove in the prior art for grouting, machining is easy and convenient, the integrity of the prestressed hollow slab is not damaged, meanwhile, hands can conveniently stretch into the long circular hole to adjust the positions of the truss ribs, and the concrete pouring situation in a prefabricated hole can be easilyobserved.
本发明涉及建筑结构技术领域，提供了一种预应力空心板连接节点构造，待连接的预应力空心板搁置于钢梁上翼缘两边，受力性能好，预应力空心板端下侧放置橡胶垫，使预应力空心板受力更加均匀，产生的摩擦力为预应力空心板提供侧向支撑，提高稳定性能；采用桁架筋连接两个预应力空心板，桁架筋为标准化生产件，可直接进行批量采购，从而降低采购成本，提高精度，桁架筋三道纵筋直径较大，桁架筋呈三棱状更加稳定，抗剪作用更强，浇筑混凝土后桁架筋和混凝土结合的更为紧密，整体性更好；在预应力空心板上切割两个圆孔交错成的长圆孔代替现有技术中的通长槽进行灌浆，不仅加工简便，还在不破坏预应力空心板整体性的同时，方便手伸入长圆孔中调节桁架筋位置，也易于观察预制孔内混凝土浇筑情况。
