The base comprises a chassis 2, a lower bracket 5, an upper bracket 7, a resting point 8 and a supporting rod 9. In this embodiment, square steel pipes are used for the underframe 2, the lower bracket 5, the upper bracket 7 and the support bar 9. However, in the actual construction process, the steel can be replaced by other section steel such as round steel pipe, channel steel, I-steel and the like, so long as the strength and rigidity of the material are ensured to meet the requirements of the support structure steel bars.

The underframe 2 is arranged at two sides of the template surface 1 where the structural steel bars 3 are required to be placed. In order to improve the stability of the base, the chassis 2 adopted in this embodiment is welded as a whole by a transverse steel pipe and a longitudinal steel pipe which are perpendicular to each other. A lower bracket 5 is welded above the underframe 2, and the bottom of the lower bracket 5 is vertically fixed on the underframe 2. The upper end of the lower bracket 5 is provided with a plurality of holes for arranging the fixing pieces 6 at intervals, and the holes are vertically arranged along the lower bracket 5.

In the process of assembling the bracket, after the lower end of the upper bracket 7 is adjusted to be inserted into the relative position of the lower bracket 5, bolts sequentially pass through the lower bracket 5 and holes on the upper bracket 7, and nuts are screwed, so that the upper bracket 7 and the lower bracket 5 are fixedly connected. In the actual construction process, the height of the support can be adjusted according to the height of the structural steel bars 3 to be hoisted.

The upper bracket 7 is also fixed with a rest point 8 for placing a support rod 9, and in this embodiment, the rest point 8 is angle steel. The angle steel is welded on the inner side of the upper bracket 7 to provide a supporting point for the supporting rod 9. As shown in fig. 1, the support rods 9 are provided between the bases on both sides to provide support for the structural steel bars 3. The supporting rod 9 is directly placed on the angle steel, and the length of the supporting rod 9 can be adjusted to adapt to the structural steel bars with different widths.
