Preferably, the method comprises the following steps: the bottom and the top of the side limiting rod are provided with limiting holes with the diameter larger than that of the limiting threaded rod, and a gasket is arranged between the side limiting rod and the nut.
The utility model has the advantages that:
(1) the utility model discloses set up at steel reinforcement cage inside and hold in the palm, can prevent effectively that steel reinforcement cage from taking place to warp because of inside cavity at the in-process of lifting by crane.
(2) The utility model discloses set up the gag lever post in bottom and side, steel reinforcement cage is hugged closely to the gag lever post in the side, prevents that steel reinforcement cage hoist and mount process from appearing rocking, and the bottom die-pin holds in the palm steel reinforcement cage, prevents to lift by crane the in-process steel reinforcement cage and warp under the action of gravity.
