Further, described adjustable jack also comprises at least two stiffeners, and described stiffener is a right angle triangle stiffener, and two adjacent right-angle sides of each described stiffener are welded and fixed mutually with the bottom surface of described short steel pipes and supporting plate respectively.
The utility model has the advantage of:
The supporting plate of rest is arranged with a short steel pipes, and identical with the external diameter of the supporting steel pipe of template, the supporting steel pipe that conveniently utilizes fastener and level carries out adjustable jack in length and breadth to reduce the jib-length of adjustable jack to reinforcement by connection, guarantees the stability of the support system of template;
Described short steel pipes and screw rod phase spiral shell dress, the two can carry out height-fine adjustment, so that shuttering supporting adjustable jack integral body can guarantee consistent level height, improves the stability of the support system of template, and highly versatile;
Two adjacent right-angle sides of each described stiffener are welded and fixed with the phase bottom surface of described short steel pipes and supporting plate respectively, can strengthen rigidity and the bearing capacity of fluted body supporting plate.
In a word, the utility model is simple in structure, reasonable stress, use operation with reinforce convenient, effectively reduce the adjustable jack jib-length, guarantee the stable of support system, the construction safety coefficient is high.
