Large-tonnage skew temporary prestressed steel beam tensioning and anchoring device
The large-tonnage skew temporary prestressed steel beam tensioning and anchoring device comprises an anchor plate and an anchoring pedestal, the anchor plate is obliquely arranged and pre-embedded in the inclined side face of concrete, two pre-embedded anchoring structures are symmetrically arranged at the left end and the right end of the inner side of the anchor plate, and an anchor plate hole is formed in the center of the anchor plate in the horizontal direction; the anchoring pedestal is installed on the outer side face of the anchor plate, the end face, away from the anchor plate, of the anchoring pedestal is a vertical face, the anchoring pedestal is provided with an anchorage device on the end face, and a channel is formed in the center of the anchoring pedestal. When the outer surface of concrete obliquely intersects with the prestressed steel beam, the prestressed steel beam is tensioned and anchored, the anchoring pedestal transmits anchoring counter-force to the pedestal bottom plate through the shear pressing plate, force transmission is clear, the embedded part mainly bears tangential shear force and normal pressure, friction force between the embedded part and concrete can offset part of the tangential shear force, and the anchoring counter-force is reduced. And the anchor bars are small in stress and reasonable in structural stress.
本发明提供了一种大吨位斜交临时预应力钢束张拉锚固装置，包括锚板和锚固台座，锚板倾斜设置并预埋于混凝土斜侧面，锚板内侧左右端对称设有两个预埋锚固结构，锚板中心处水平方向设有锚板孔；锚固台座安装于锚板外侧面，锚固台座背离锚板的端面为竖直面，锚固台座在该端面设有锚具，锚固台座中心处设有通道。本发明适用于混凝土外表面与预应力钢束斜交时，预应力钢束的张拉锚固，锚固台座通过剪压板将锚固反力传递至台座底板，传力明确，预埋件则主要承受切向剪力和法向压力，预埋件与混凝土之间的摩擦力能够抵消部分切向剪力，锚筋受力小，结构受力合理。
