Reinforcing steel bar connecting structure for prefabricated parts and mounting method of reinforcing steel bar connecting structure
The invention relates to a steel bar connecting structure of a prefabricated part. The steel bar connecting structure comprises a combined connecting sleeve, two fastening sleeves and two steel bars. The combined connecting sleeve is composed of two symmetrical semi-circular-ring cylinder bodies, the middle of each semi-circular-ring cylinder body protrudes outwards to form a radius expanding area, external threads are arranged at the two ends of each semi-circular-ring cylinder body, the combined connecting sleeve is arranged at the head-to-tail connecting position of the two reinforcing steel bars in a sleeving mode, and limiting blocks are fixedly arranged at the corresponding ends of the two reinforcing steel bars respectively. The two limiting blocks are placed in a cavity defined by the two radius expanding areas, and the two fastening sleeves are connected to the two ends of the combined connecting sleeve in a threaded mode to fix the combined connecting sleeve and the two steel bars into a whole. The combined connecting sleeve is tightly pressed on the reinforcing steel bars through the fastening sleeve, and mechanical connection between the reinforcing steel bars is achieved. The connection strength of the steel bar connection structure is greatly improved through the combined action of clamping and limiting of the radius expansion area on the limiting block and the friction force between the semi-circular ring cylinder body and the steel bars.
本发明涉及一种预制构件的钢筋连接构造，包括组合式连接套筒、两个紧固套筒和两根钢筋。所述组合式连接套筒由两个对称的半圆环筒体组成，每个半圆环筒体的中部向外凸出形成半径扩大区，所述半圆环筒体的两端设有外螺纹，所述组合式连接套筒套装在两根钢筋的首尾连接处，两根钢筋的对应端各固设限位块，两个限位块放置在两个半径扩大区围成的空腔内，两个紧固套筒螺接在组合式连接套筒的两端将组合式连接套筒与两根钢筋固定为一体。本发明由紧固套筒将组合式连接套筒紧压在钢筋上，实现了钢筋间的机械连接。通过半径扩大区对限位块的卡置限位加上半圆环筒体与钢筋间的摩擦力的共同作用，大大增加了钢筋连接构造的连接强度。
