Corner energy dissipation prefabricated assembly joint and construction method thereof
The invention discloses a corner energy dissipation prefabricated assembly joint which comprises a concrete prefabricated beam, a concrete prefabricated column, a concrete steel plate embedded part, a rotary shear steel bar and a high-strength ductile material. One concrete steel plate embedded part is embedded in one end face of the concrete prefabricated beam, and the other concrete steel plate embedded part is embedded in the side wall of the concrete prefabricated column; the rotary shear steel bar is clamped between the two concrete steel plate embedded parts; the high-strength ductile material is poured in a space defined by the rotary shear steel bar and the concrete steel plate embedded parts on the two sides, and the rotary shear steel bar and the concrete steel plate embedded parts on the two sides are connected and fixed; built-in pre-stress preformed holes allowing force steel strands to penetrate through are formed in the concrete precast beam, the concrete precast column, the concrete steel plate embedded part in the width direction and the rotary shear steel bar in the radial direction. Damage caused by cracking of the plastic hinges is delayed by rotating the shear steel bars, the flexibility of the joint is improved, and the damage degree of the joint area is reduced.
本发明公开了一种转角耗能预制拼装节点，包括：混凝土预制梁、混凝土预制柱、混凝土钢板预埋件、旋转剪力钢棒、高强度延性材料；一个混凝土钢板预埋件预埋在混凝土预制梁的一端面上，另一混凝土钢板预埋件预埋在混凝土预制柱的侧壁上；旋转剪力钢棒夹持在两个混凝土钢板预埋件之间；高强度延性材料浇筑在旋转剪力钢棒与两侧混凝土钢板预埋件围城的空间中，连接固定旋转剪力钢棒与两侧混凝土钢板预埋件；混凝土预制梁内、混凝土预制柱内、混凝土钢板预埋件宽度方向上、旋转剪力钢棒的径向上都开设有供应力钢绞线穿过的内置预应力预留孔。本发明通过旋转剪力钢棒延迟塑性铰开裂导致的破坏，提高了节点的柔性，降低了节点区域的损伤程度。
