Device capable of recycling main reinforcements of fender posts and using method
The device comprises an inner sleeve, an outer sleeve assembly, an inner sleeve cracking assembly and a steel bar main reinforcement, the outer sleeve assembly comprises an outer sleeve, the diameter of one end of the inner sleeve is smaller than that of the other end of the inner sleeve, the smaller end of the inner sleeve is provided with a prefabricated crack, the inner sleeve penetrates into the outer sleeve, and the inner sleeve cracking assembly is connected with the outer sleeve; the inner sleeve fracturing assembly comprises a first screw rod, a second screw rod, two splitting nicking tools and a connecting sleeve, the first screw rod controls the movement direction through a main rib end groove and a first screw rod guide hole, the main rib is rotated to push the first screw rod to rotate so as to drive the second screw rod to rotate, and the connecting sleeve drives the splitting nicking tools to move along splitting nicking tool limiting grooves so as to enable the splitting nicking tools to be split. Therefore, the inner sleeve is damaged. According to the recyclable main reinforcement device, recycling of the fender post main reinforcements can be achieved, tensioning force can be prevented from being applied to the reinforcements, and therefore the strength of the recycled main reinforcements is guaranteed, the number of times of reuse of the main reinforcements is increased, and the recyclable main reinforcement device has important significance in reducing construction cost and reducing carbon emission.
一种可实现围护桩主筋回收的装置及使用方法，包括内套管、外套管组件、内套管致裂组件和钢筋主筋，外套管组件包括外套管，内套管的一端直径小于另一端，较小的一端上设有预制裂纹且内套管穿入外套管内，内套管致裂组件包括第一螺杆、第二螺杆、两个劈裂刻刀和连接套管，第一螺杆通过主筋端部凹槽和第一螺杆导向孔控制运动方向，转动主筋推动第一螺杆旋转，从而带动第二螺杆转动，连接套管带动劈裂刻刀沿着劈裂刻刀限位槽运动，从而破坏内套管。本发明的可回收主筋装置，可以实现围护桩主筋的回收利用，也可避免对钢筋施加张拉力，从而保证回收主筋的强度，提高主筋重复使用次数，对于减低施工成本、减少碳排放具有重要的意义。
