Portable hole-shaped floor supporting frame fixing device
The utility model discloses a portable hole-shaped floor supporting frame fixing device. The portable hole-shaped floor supporting frame fixing device comprises at least two first connecting rods, a reinforcing component and a second connecting rod. The first connecting rods are arranged on the peripheral sides of the supporting frame stand columns correspondingly. One end of the first connecting rod is connected with one end of the reinforcing component, the other end of the reinforcing component is connected with the second connecting rods, the second connecting rods are arranged close to the inner side of a floor hole, and the at least two second connecting rods are used for being fixed to the floor hole. Through the combination of the at least two first connecting rods, the reinforcing components and the second connecting rods, a multi-direction fixing structure surrounding the supporting frame stand columns is formed, compared with a traditional single-point-position fixing mode, the anti-overturning capacity and the horizontal positioning precision of the supporting frame on the hole-shaped floor can be remarkably improved, dislocation or moving caused by insufficient single-point stress is avoided, and the supporting frame can be conveniently and rapidly fixed. Meanwhile, loads are dispersed through multidirectional cooperative stress, and local damage to the floor edge is reduced.
