预应力钢筋锚具及钢筋有效预应力实时监测系统
摘要：
本发明公开一种预应力钢筋锚具及钢筋有效预应力实时监测系统。锚具包括夹片(1)、锚环(2)，锚环(2)内壁前部设有与夹片(1)外形匹配的锥孔(3)，其特征在于：还包括多个电阻应变片(4)，所述电阻应变片(4)贴敷在锥孔(3)之后的锚环(2)的外壁上。实时监测系统包括电阻应变仪(6)和与之电连接的多个电阻应变片(4)，所述电阻应变片(4)贴敷在预应力钢筋锚具的锚环(2)外壁上，并位于锚环(2)的锥孔(3)之后。本发明的锚具组成的钢筋有效预应力实时监测系统，能实现钢筋有效预应力的实时监测。
摘要（英）：

The invention discloses a prestressed reinforcement anchorage device and a real-time monitoring system for effective prestress of reinforcements. The prestressed reinforcement anchorage device comprises clamping pieces (1) and anchor rings (2), and conical holes (3) matched with the clamping pieces (1) in shape are formed in the front portions of the inner walls of the anchor rings (2). The prestressed reinforcement anchorage device is characterized by further comprising a plurality of resistance strain gages (4) which are pasted to the portions, behind the conical holes (3), of the anchor rings (2). The real-time monitoring system comprises a resistance strain gauge (6) and the resistance strain gages (4) electrically connected with the resistance strain gauge (6), and the resistance strain gages (4) are pasted to the outer walls of the anchor rings (2) of the prestressed reinforcement anchorage device and located behind the conical holes (3) of the anchor rings (2). The real-time monitoring system, composed of the anchorage device, for the effective prestress of the reinforcements can monitor the effective prestress of the reinforcements in real time.
