Fabricated concrete double-T plate abutted seam bolt connection structure
The invention relates to a fabricated concrete double-T-plate abutted seam bolt connection structure, aims to solve the problem of abutted seam connection of double-T-plate flanges in a fabricated building large-span floor (roof) structure system, and belongs to the technical field of structural engineering. The connection structure comprises two T-shaped steel plates, anchor bars welded to the T-shaped steel plates, connecting steel plates used for fixing the two T-shaped steel plates, high-strength bolts and circular washers; each double-T-plate flange comprises a layer of reinforcing mesh formed by laying longitudinal and transverse reinforcing steel bars and a rectangular notch located in the side edge of the plate and facilitating installation of a bolt connecting piece; and concretelaminated layers are poured on the upper portions of the the double T-shaped plate flanges and the bolt connecting pieces, and the connecting performance of the abutted seams and the overall performance of the double T-shaped plate floor system are enhanced. The connecting structure is reliable in quality, convenient to construct and reasonable in stress, the damaged connecting piece is easy to repair under the action of the horizontal earthquake load, and the applicability is high.
本发明涉及一种装配式混凝土双T板拼缝螺栓连接结构，以解决装配式建筑大跨度楼（屋）盖结构体系中双T板翼缘的拼缝连接问题，属于结构工程技术领域。本发明包括两个T型钢板、与T型钢板焊接的锚筋和用于固定两个T型钢板的连接钢板、高强螺栓、圆形垫圈；所述双T板翼缘包括一层由纵横钢筋铺设的钢筋网片及位于板侧边便于螺栓连接件安装的矩形凹口；所述双T板翼缘上部及螺栓连接件处浇筑混凝土叠合层，增强拼缝处连接性能及双T板楼盖的整体性能。本发明的连接结构质量可靠，施工便捷，受力合理，在水平地震荷载作用下连接件损坏易修复，适用性较强。
