Self-stress connecting structure suitable for fabricated pavement slab and construction method
The invention discloses a self-stress connecting structure suitable for a fabricated pavement slab and a construction method. The self-stress connecting structure comprises a straightway connecting structure, a curve connecting structure I and a curve connecting structure II, each connecting structure is composed of an assembly type prestress plate, a self-stress synergistic device, a connecting seam, a self-stress steel bar structure and a steel fiber expansion concrete structure. The straight road section of the connecting structure adopts a straight edge equal-width structure, and the curve road section adopts a zigzag equal-width structure and a zigzag unequal-width structure. In addition, the invention further discloses a construction method of the fabricated prestressed plate, the self-stress synergistic device, the connecting seam, the self-stress steel bar structure and the steel fiber expansive concrete structure. The self-stress connecting structure is not tensioned and grouted on site, and the process is simple; cracking is not prone to occurring, and the service life is long; the veneers are easy to replace after being damaged, and maintenance cost is low; the sawtooth-shaped connecting structure solves the problem that prestressed tendons are difficult to be arranged on the assembly type prestressed pavement at the bend.
本发明公开了一种适用于装配式路面板的自应力连接结构及施工方法，所述自应力连接结构包括：直道连接结构和弯道连接结构一、弯道连接结构二，所述连接结构均由装配式预应力板、自应力增效装置、连接缝、自应力钢筋结构、钢纤维膨胀混凝土结构组成。连接结构直道路段采用直边等宽结构，弯道路段采用锯齿状等宽结构和锯齿状不等宽结构两种形式。此外，还公开了装配式预应力板、自应力增效装置、连接缝、自应力钢筋结构与钢纤维膨胀混凝土结构的施工方法。自应力连接结构不现场张拉压浆，工艺简单；不易开裂，使用寿命长；单板损坏后易更换，养护成本低；锯齿状连接结构解决了弯道处装配式预应力路面配预应力筋难的问题。
