[0007] A steel bar welded mesh, which is welded on the connecting steel bars;

[0008] A hook, which is arranged parallel to the formwork and extends upward or downward in the parallel direction of the formwork.

[0009] In the above hoisting structure for a formed steel bar skeleton, the steel bar welded mesh includes horizontal steel bars and vertical steel bars welded to each other, and the tail of the hook is welded to the vertical steel bars.

[0026] In the present utility model, connecting the two templates through the connecting steel bars 4 inside the formed steel bar framework can realize the synchronous hoisting of the templates and the formed steel bar framework, with high on-site construction efficiency. Setting the lifting hook on the steel bar welded mesh 5 of the formed steel bar framework can avoid damage to the steel bars at the hoisting part during the hoisting of the formed steel bar framework. The lifting hook extending upward or downward in the parallel direction of the templates 1 enables the lifting hook to be used as the built-in steel bars in the upper and lower layer wall bodies after the templates are hoisted, without the need to cut the lifting hook after hoisting.

[0027] Specifically, the steel bar welded mesh 5 includes horizontal steel bars 7 and vertical steel bars 8 welded to each other. The tail of the lifting hook 6 is welded to the vertical steel bar 8 so that the lifting hook 6 is in the same direction as the vertical steel bar 8, thereby enabling the lifting hook to be used as the built-in steel bars in the upper and lower layer wall bodies.

[0028] Specifically, the lifting hook 6 is made of U-shaped steel bars.

[0029] Preferably, the connecting steel bars 4 are detachably fixed to the templates 1 through a sleeve structure, which can facilitate the separate independent transportation of the formed steel bar framework and the templates and rapid assembly on-site. Of course, it can also be assembled together in the factory and then transported together, giving users more transportation options.

[0030] Specifically, the sleeve structure includes end plates 9 and connecting sleeves 10. An internal threaded hole 11 is provided inside the connecting sleeve 10. The connecting sleeve 10 is inserted into a connecting hole on the template 1. Both ends of the connecting steel bar 4 have threaded ends 12, and the threaded ends 12 are screwed into the internal threaded hole 11. After inserting the sleeve into the connecting hole of the template and screwing the threaded end of the connecting steel bar into the threaded hole of the sleeve, the assembly of the formed steel bar framework and the template can be completed.

[0031] Specifically, the cross-sectional shape of the end plate 9 is quadrilateral, pentagonal or polygonal.

[0032] Specifically, the connecting steel bar 4 and one side end plate 9 can also form a combined rod 13.
