Zusammenfassung: | The invention belongs to the field of building construction and mainly relates to a counter-pull supporting tool for a slab-strip bottom formwork of a PC laminated slab. According to the counter-pullsupporting tool, an arranged upper fixing piece is placed on the upper part of the laminated slab through supporting pieces, an arranged lower fixing piece is placed on the lower part of the slab-strip bottom formwork, a lead screw penetrates through holes to connect the upper fixing piece with the lower fixing piece, and fasteners are arranged at the two ends of the lead screw to fasten the upperfixing piece and the lower fixing piece. The counter-pull supporting tool is adopted for counter-pull supporting from the slab surface, it is guaranteed that the slab-strip bottom formwork of the laminated slab is closely attached to the formwork, force bearing is uniform, and the problem that the elevation of the formwork exceeds the height is avoided; the fixing pieces are arranged to be in a soft and hard material comb |
