Device for preventing prestress tension box from floating upwards during concrete pouring
The invention relates to the technical field of installation of a tension box during concrete pouring, in particular to a device for preventing a prestress tension box from floating upwards during concrete pouring. A transverse telescopic rod is slidably inserted into the lower end of a right-angle air channel, and a double-conical-surface conical block located in a screw hole is arranged at the end of the transverse telescopic rod; the device has the beneficial effects that the longitudinal lifting rod is jacked up through extrusion of the double-conical-surface conical block, the tensioning box is separated from concrete, disassembly is convenient, the conical nut and the bolt synchronously rotate through lateral extension of the jacking rod, separation of the conical nut and the concrete is achieved, and the device is simple in structure, convenient to use and high in practicability. Therefore, by means of rotation of the bolt, segmented separation of the tensioning box and the nut is achieved, the number of dismounting steps is greatly reduced, the requirement for a dismounting tool is greatly reduced, and the dismounting efficiency is improved.
本发明涉及混凝土浇筑时张力盒的安装技术领域，具体为一种防止在浇筑混凝土时预应力张拉盒上浮装置，直角气道的下端滑动插接有横向伸缩杆，所述横向伸缩杆的端部设置有位于螺孔中的双锥面锥块，螺栓的下端外壁设置有与双锥面锥块配合的圆环状锥槽，有益效果为：利用双锥面锥块的挤压，使得纵向升降杆顶起，张拉盒与混凝土分离，便于拆卸，利用顶杆的侧向延伸，使得锥形螺母与螺栓同步转动，实现锥形螺母与混凝土的分离，从而利用螺栓的转动，实现张拉盒与螺母的分段分离，大大降低了拆卸的步骤和对拆卸工具的要求，提高了拆卸的效率。
