Steel bar inclined interaction locking bridge deck slab connecting structure and design method
The invention discloses a reinforcing steel bar inclined interactive locking bridge deck slab connecting structure and a design method. A first prefabricated bridge deck slab and a second prefabricated bridge deck slab reserve first inclined gate-type reinforcing steel bars and second inclined gate-type reinforcing steel bars at the transverse end of a wet joint correspondingly and are arranged at equal intervals in the length direction of the wet joint; the first inclined door-type steel bar and the second inclined door-type steel bar are mutually sleeved and locked to form an inclined interaction locking shape, the horizontal lap joint length of the inclined interaction locking inclined door-type steel bars and the minimum width of the wet joint are determined, and at least four longitudinal straight line penetrating steel bars vertically penetrate through the whole wet joint length from the corners of the inner periphery of a hole channel formed by inclined interaction locking. By means of the first inclined door-type steel bars and the second inclined door-type steel bars which are arranged in the inclined mode, the length of the middle-section rotary steel bars is increased, the problem that thin plate structure connecting steel bars cannot be bent in a rotary mode is solved, the tensile bearing capacity of connection is greatly improved compared with linear steel bars, and meanwhile the lap joint length of the reserved steel bars can be reduced.
本发明公开了一种钢筋斜交互锁桥面板连接结构及设计方法，第一预制桥面板和第二预制桥面板在湿接缝横向端部分别预留第一斜向门式钢筋和第二斜向门式钢筋，并沿着湿接缝长度方向等间距布置；第一斜向门式钢筋与第二斜向门式钢筋相互套锁呈斜交互锁状，并确定斜交互锁的斜向门式钢筋的水平搭接长度及湿接缝的最小宽度，至少4根纵向直线贯穿钢筋从斜交互锁形成的孔道内周边转角处垂直贯穿整个湿接缝长度。本发明利用斜向设置的第一斜向门式钢筋和第二斜向门式钢筋，增大中段回转钢筋的长度，解决薄板结构连接钢筋无法回转弯折的情况，相对于直线筋大大提高连接的抗拉承载力，同时也可以减少预留钢筋的搭接长度。
