Special-shaped concrete cross beam formwork bottom supporting device
The invention relates to a special-shaped concrete beam formwork bottom supporting device which comprises a base, a plurality of first hydraulic cylinders are fixed to the upper end face of the base, a transverse pipe is arranged between every two first hydraulic cylinders, and a second hydraulic cylinder is fixed to the middle of the lower end face of the base. A piston rod of the second hydraulic cylinder moves upwards to press hydraulic oil in the second hydraulic cylinder into a cavity in the lower end of the first hydraulic cylinder, a cavity in the upper side of the second hydraulic cylinder is communicated with the transverse pipes in the middle, an opening is formed in the upper end of each transverse pipe, and a blocking block capable of moving up and down along the opening is arranged in each opening. Under the condition of no external force, the blocking block cannot move downwards, and when the second hydraulic cylinder is under positive pressure, the blocking block can quickly move downwards; the lower end face of the cross beam formwork is divided into a plurality of units for independent supporting through the multiple sets of first hydraulic cylinders, multi-supporting-point supporting can be conducted on the formwork with the special-shaped lower end face through different lifting heights of the piston rods, and the mold supporting stability is greatly improved.
本发明涉及一种异形混凝土横梁模板底部支撑装置，包括底座，底座上端面固定有多个第一液压缸，每个第一液压缸之间均设置有横管，底座下端面中部固定有一个第二液压缸，第二液压缸的活塞杆向上移动能将第二液压缸内的液压油压入第一液压缸下端腔体，第二液压缸上侧腔体与中部的横管相互连通，每个横管的上端均开设有一个开口，每个开口内均设置有一个能沿开口上下移动的堵块，在不受外力的情况下，堵块无法向下移动，当第二液压缸正压时，堵块能快速向下移动；本发明通过多组第一液压缸，将横梁模板下端面划分为多个单元进行独立支撑，对于下端面为异形的模板，能够通过活塞杆上升高度的不同进行多支点支撑，大大提高模具支撑的稳定性。
