Pore-forming device and pore-forming method for pre-stressed steel bundle preformed hole
The invention relates to a pore-forming device and a pore-forming method for a pre-stressed steel bundle preformed hole, and relates to the technical field of concrete engineering construction. The pore-forming device is used for a concrete structure of a steel template. The pore-forming device comprises a steel main beam and a steel cylinder, wherein the steel main beam is horizontally arranged above the steel template; the two ends of the steel main beam are fixedly equipped with a steel beam separately; the bottom surface of each steel beam abuts against the top surface of the steel template; the top end of the steel cylinder is perpendicularly fixed on the steel main beam, and the bottom end surface of the steel cylinder is sealed; and a spiral rubber strip is wound in the peripheral direction of the steel cylinder, and is inserted into the concrete structure to form the pre-stressed steel bundle preformed hole. The pore-forming device and the pore-forming method can simply and efficiently realize forming of the pre-stressed steel bundle preformed hole with a large diameter and a long depth.
本申请涉及一种预应力钢束预留孔的成孔装置及成孔方法，涉及混凝土工程施工技术领域，用于钢模板的混凝土结构，所述成孔装置包含：钢主梁，其水平设置于所述钢模板上方，所述钢主梁的两端分别固定设置一根钢横梁，所述钢横梁的底面抵持在所述钢模板的顶面；钢筒，其顶端垂直固定于所述钢主梁，其底端面封闭；所述钢筒周向缠绕螺旋状的橡胶条，并插入所述混凝土结构内形成预应力钢束预留孔。本申请的成孔装置和成孔方法，能够简单高效实现大直径、长深度的预应力钢束预留孔的成型。
