Prestress fixed end construction device
The invention provides a prestressed fixed end construction device, and belongs to the field of constructions.The prestressed fixed end construction device is provided with a restraint ring, a prestressed tendon group is arranged at the bottom of the restraint ring, and a buffer mechanism, a first supporting arc surface and a second supporting arc surface are sequentially arranged on the side wall of the prestressed tendon group from inside to outside; the prestressed tendon group comprises first-stage prestressed tendons, second-stage prestressed tendons and third-stage prestressed tendons; the supporting structure is characterized in that the contact surface of the second-stage prestressed tendon and the first supporting cambered surface is an arc-shaped surface matched with the cambered surface of the first supporting cambered surface, and the contact surface of the third-stage prestressed tendon and the second supporting cambered surface is an arc-shaped surface matched with the cambered surface of the second supporting cambered surface; the arc shape of the bottom surface of the second supporting arc surface is matched with the arc shape of the top surface of the first supporting arc surface; the device solves the problem that the stress surface of the contact surface of the prestress fixing device is changed, and the stress of the contact surface can be more uniform.
本发明提供了一种预应力固定端施工装置，属于建筑领域，该预应力固定端施工装置具有约束圈，所述约束圈的底部设置有预应力筋群，所述预应力筋群的侧壁上从内到外依设置有缓冲机构、第一支撑弧面、第二支撑弧面，所述预应力筋群包括第一级预应力筋、第二级预应力筋以及第三级预应力筋；其特征在于，所述第二级预应力筋与所述第一支撑弧面的接触面为与所述第一支撑弧面的弧面相适配的弧形面，所述第三级预应力筋与所述第二支撑弧面的接触面为与所述第二支撑弧面的弧面相适配的弧形面，所述第二支撑弧面底面弧形与所述第一支撑弧面的顶面弧形相适配；该装置解决了预应力固定装置接触面受力面变化的问题，能够使接触面的受力更加均匀。
