Municipal road and bridge pre-tensioning method prestress releasing construction device
The municipal road and bridge pre-tensioning method prestress releasing construction device structurally comprises a fixed bottom plate, a locking plate, a controller and a releasing mechanism, the locking plate is arranged at the bottom of the outer side of the fixed bottom plate, the controller is installed on the upper end face of the releasing mechanism and electrically connected with the releasing mechanism, and magnetic buckle plates on the two sides are externally pressed through steel bars; meanwhile, the magnetic buckle plates on the two sides attract each other, so that the outer sides of the reinforcing steel bars are automatically buckled, the situation that the reinforcing steel bars are staggered and separated in the through holes in the tensioning process is avoided, then the jack is controlled by the controller to push the whole steel tightening mechanism, and therefore the reinforcing steel bars are effectively tensioned; sliding wheels on the two sides carry out auxiliary sliding in the upper end of the fixed bottom plate, the sliding smoothness of the sliding block in the upper end of the bottom plate is improved, meanwhile, a magnetic attraction frame applies magnetic attraction force to the sliding block, the sliding stability of the sliding block in the upper end of the bottom plate is improved, and it is avoided that a steel bar applies pull-back force to a pushing pull plate.
本发明公开了一种市政路桥先张法预应力放张施工装置，其结构包括固定底板、锁紧板、控制器、放张机构，固定底板外侧底部设有锁紧板，控制器安装在放张机构上端面并且电连接，通过钢筋对两侧的磁力扣板进行外压，同时两侧的磁力扣板相互吸附，从而将钢筋外侧进行自动扣紧，避免钢筋在张拉的过程中在通孔内部发生错位分离，接着经过控制器控制千斤顶将紧钢机构整体进行推移，从而将钢筋进行有效的张拉，通过两侧的滑轮在固定底板上端内部进行辅助滑动，提高滑动块在底板上端内部滑动的顺畅度，同时磁吸框对滑动块施加磁性吸附力，提高滑动块在底板上端内部滑动时稳定性，避免钢筋对推移拉板施加回拉力。
