Movable pedestal for prefabricating concrete beam through post-tensioning method
The invention discloses a movable pedestal for prefabricating a concrete beam through a post-tensioning method, and aims at solving problems that in the prior art, when a beam body is tensioned, the bottom side portions of the two ends can be seriously damaged due to stress concentration and heavy pressure friction, and the quality and the appearance of the beam body are affected. The technical key point is that the movable pedestal comprises a pedestal main body and symmetrical pedestal end sections, and the movable pedestal is characterized in that each pedestal end section is formed by matching a pedestal end section lower part and a pedestal end section upper part, the pedestal end section lower parts and the pedestal main body are connected into a whole, and the top surface of each pedestal end section lower part is provided with an arc downward concave part; and the bottom surface of the each pedestal end section upper part is provided with an arc convex part which is rotationally matched with the arc downward concave part; and when the pedestal end section upper parts are in a horizontal state, set first gaps are reserved between the outer side parts of the bottom surfaces of the pedestal end section upper parts and the outer side parts of the top surfaces of the pedestal end section lower parts, set second gaps are reserved between the inner side parts of the cambered surfaces of the arc convex parts and the inner side parts of the cambered surfaces of the arc downward concave parts, and the top surfaces of the pedestal end section upper parts are flush with the top surface of the pedestal main body.
一种可活动型后张法预制混凝土梁的台座。本发明是为了解决现有技术存在梁体被张拉时两端底侧部位由于应力集中和重压摩擦后会受到严重损坏，影响梁体质量和外观的问题。技术要点：包括台座主体和对称的台座端段，特征是台座端段由台座端段下部和台座端段上部配合构成，台座端段下部与台座主体连结为一体，台座端段下部顶面设有圆弧下凹部位，台座端段上部底面设有与圆弧下凹部位转动配合的圆弧凸出部位，台座端段上部处于水平状态时，台座端段上部的底面外侧部分与台座端段下部的顶面外侧部分之间留有设定的第一间隙、且圆弧凸出部位的弧面内侧部分与圆弧下凹部位的弧面内侧部分之间留有设定的第二间隙、且台座端段上部的顶面与台座主体的顶面齐平。
