Reinforcing steel bar grouting sleeve connecting component with deformation energy dissipation characteristic and connecting method of reinforcing steel bar grouting sleeve connecting component
The invention belongs to the technical field of structural engineering, and particularly relates to a reinforcing steel bar grouting sleeve connecting component with deformation energy dissipation characteristics and a connecting method thereof.The component comprises an annular cylinder, a viscoelastic damping material layer, a force transmission reinforcing steel bar and a semi-grouting sleeve. Before the prefabricated part is manufactured, an organic whole of the annular cylinder, the viscoelastic damping layer and the force transmission steel bars is in threaded connection with the connecting steel bars of the part on one side in advance through threads; the semi-grouting sleeve is in threaded connection with the force transmission steel bar; in the prefabricated part splicing process, the connecting steel bar of the component on the other side is arranged in the semi-grouting sleeve in a centering mode, grouting materials are injected, and steel bar grouting sleeve connection with the deformation energy dissipation characteristic is achieved. Compared with the problem of shock loss of a connecting structure in an earthquake caused by existing rigid hard connection, the rigid hard connection can be converted into flexible soft connection with certain rigidity, deformation and energy consumption can be conducted to a certain degree through the viscoelastic damping material layer, and structural damage can be reduced.
本发明属于结构工程技术领域，具体涉及一种具有变形耗能特性的钢筋灌浆套筒连接构件及其连接方法，本构件包括环形筒体、黏弹性阻尼材料层、传力钢筋以及半灌浆套筒。在预制构件制作前，预先将环形筒体、黏弹性阻尼层以及传力钢筋的有机整体通过螺纹与一侧构件的连接钢筋实现螺纹连接；将半灌浆套筒与传力钢筋实现螺纹连接；在预制构件拼接中，将另一侧构件的连接钢筋，对中置于半灌浆套筒中，注入灌浆材料，实现具有变形耗能特性的钢筋灌浆套筒连接。相比于现有刚性硬连接造成地震中连接结构震损失效的问题，本发明可将刚性硬连接转换为具有一定刚度的柔性软连接，可以利用黏弹性阻尼材料层在一定程度上进行变形与耗能，有利于减少结构损害。
