Non-rib-out seamless splicing prestressed concrete steel structure type composite floor slab
The invention discloses a non-reinforcement seamless splicing prestressed concrete steel structure type composite floor slab which comprises a prefabricated bottom plate, prestressed reinforcements, distributed reinforcements and a cast-in-place concrete layer arranged above the prefabricated bottom plate, the prestressed reinforcements and the distributed reinforcements are longitudinally and transversely installed in the prefabricated bottom plate, the distributed reinforcements are arranged above a steel structure, and the upper end of the steel structure penetrates through the top face of the prefabricated bottom plate. A plurality of long reserved grooves are formed in the front side and the rear side of the upper end of the prefabricated bottom plate. A plurality of linear long reserved grooves or T-shaped long reserved grooves are formed in a prefabricated bottom plate at equal intervals, distributed steel bars do not need to extend outwards, after seamless butt joint is conducted on the prefabricated bottom plate, a linear long thread splicing rib or an I-shaped long thread splicing rib is inserted into the two spliced reserved grooves, and finally concrete is cast in place. In this way, the threaded splicing ribs are additionally arranged in the grooves to play a role in reinforcing connection, so that the ribs are not exposed, seamless tight connection between the plates is achieved, and the construction safety and the quality of the spliced concrete prestressed laminated plates are improved.
本发明公开了一种不出筋无缝拼接预应力混凝土钢构式叠合楼板，包括预制底板、纵横安装在其内部的预应力钢筋和分布钢筋、布置在预制底板上方的现浇混凝土层，分布钢筋上方布置有钢构，钢构上端贯穿过预制底板顶面，预制底板上端前后两侧均开有多个长预留凹槽。在预制底板上等间距开设多个“一”字型长预留凹槽或“T”字型长预留凹槽，可以使分布钢筋不需要往外延伸，在对预制底板无缝对接后，将呈“一”字型的长螺纹拼接筋或“工”字型的长螺纹拼接筋插接在拼接的两个预留凹槽内部，最后现浇混凝土，这样在槽中添加螺纹拼接筋起到加固连接作用，以实现不出筋以及板间拼接无缝紧密连接，提高了施工安全性和混凝土预应力叠合板拼接后的质量。
