Dry-type prefabricated concrete bridge deck slab reinforced concrete connecting structure and manufacturing method thereof
The invention discloses a dry-type prefabricated concrete bridge deck slab reinforced concrete connecting structure and a manufacturing method thereof, and belongs to the technical field of engineering construction, the dry-type prefabricated concrete bridge deck slab reinforced concrete connecting structure comprises two to-be-connected prefabricated concrete bridge deck slabs, and paired reinforced concrete connecting pieces which are symmetrically connected left and right are arranged between the two bridge deck slabs; a U-shaped through groove with an opening facing the end of the bridge deck slab and matched with the thickness of the bridge deck slab is formed in the upper portion of the steel-concrete connecting piece. A plurality of perforated steel plates and a plurality of groups of anchoring nails are arranged in the U-shaped through groove in the extending direction of a cavity groove at intervals, wherein a plurality of finish-rolled twisted steel bars penetrate through the perforated steel plates, and the anchoring nails are meshed on transverse steel bars at the end of the bridge deck slab in an up-down tooth shape. A plurality of longitudinal annular reinforcing steel bars which are arranged at the end of the bridge deck slab in the length direction of the U-shaped through groove at intervals are deeply inserted into the U-shaped through groove and penetrate through the finish-rolled threaded reinforcing steel bars in a sleeving mode, and concrete is poured between the U-shaped through groove and the end of the bridge deck slab in a filling mode. Steel-concrete dry connection can be achieved, wet joints between traditional bridge deck slabs are replaced, the assembly construction efficiency is improved, the durability is improved, and the service life is prolonged.
本发明公开了一种干式预制混凝土桥面板钢混连接结构及其制造方法，属于工程建设技术领域，包括两个待连接预制混凝土桥面板，两个桥面板之间设有成对左右对称连接的钢混连接件；钢混连接件上部设有开口朝向桥面板端部且与桥面板厚度相匹配的U型通槽，U型通槽内沿腔槽延伸方向分别间隔设置多个穿设有若干精轧螺纹钢筋的开孔钢板和多组呈上下齿状咬合于桥面板端部横向钢筋上的锚固钉，桥面板端部沿U型通槽长度方向间隔陈列排布的若干纵向环形钢筋进深插入U型通槽并穿套于精轧螺纹钢筋，U型通槽和桥面板端部之间填充浇筑有混凝土。本发明能够实现钢混干式连接且替代传统桥面板之间湿接缝，提高装配施工效率、耐久性能和寿命周期。
