Bidirectional laminated slab dense splicing strong seam construction process and structure
The invention discloses a bidirectional laminated slab dense splicing strong seam structure. The bidirectional laminated slab dense splicing strong seam structure comprises a prefabricated slab and a cast-in-place layer, wherein bottom plate steel bars and bottom plate connecting bars are arranged in the prefabricated slab, the bottom plate steel bars comprise bottom plate load-bearing steel bars and bottom plate fixing steel bars, the bottom plate fixing steel bars are close to a splicing seam of the prefabricated slab, bent upwards and extend out of the surface of the prefabricated slab, additional steel bars and top plate compression steel bars are longitudinally laid in the cast-in-place layer, every two adjacent additional steel bars are connected to one top plate compression steel bar through a connecting web bar, the additional steel bars are perpendicular to the abutted seam, additional fixing steel bars are further arranged at the two ends of the additional steel bars and arranged in the vertical direction, and top plate connecting ribs and the top plate compression steel bars are laid in the transverse direction and in an overlapped mode. The bidirectional laminated slab dense splicing strong seam construction structure is high in integrality and bearing capacity, and the stability of the laminated slab near the abutted seam is high.
本发明公开了一种双向叠合板密拼强接缝构造，包括预制板和现浇层，预制板内设有底板钢筋以及底板连接筋，底板钢筋包括底板受力钢筋和底板固定钢筋，底板固定钢筋靠近预制板的拼缝，底板固定钢筋向上弯曲并伸出于预制板面；现浇层内纵向铺设有附加钢筋和顶板受压钢筋，相邻两根附加钢筋通过连接腹筋与一根顶板受压钢筋连接；所述附加钢筋与拼缝垂直，附加钢筋的两端还设有附加固定钢筋，所述附加固定钢筋沿竖直方向设置；顶板连接筋沿横向且与顶板受压钢筋重叠铺设。本发明整体性及承载能力强，拼缝附近叠合板的稳定性高。
