[0013] With such a structure, the double I-beam can be easily pre-positioned during installation without measuring the installation position of the double I-beam. The double I-beam can be clamped by the clamping plate and then tightened by the tension bolts.

[0014] As a further improvement of the present invention, the clamping plate is L-shaped.

[0015] With this structure, the double I-beam can be placed on the clamping plate and then clamped.

[0016] As a further improvement of the utility model, a slide plate is arranged on the clamping plate, which is padded under the steel back rib, the bottom surface of the slide plate is threadedly connected to the adjusting bolt, and the bottom surface of the clamping plate is threadedly connected to the third nut.

[0017] By adopting such a structure, the installation height of the double-jointed I-beam can be adjusted to improve the positioning effect.

[0018] As a further improvement of the utility model, a lifting lug is arranged on the steel back rib.

[0019] With such a structure, the lifting lugs make it easy to lift the steel back ribs.

[0020] The utility model avoids drilling holes on the formwork components and can also enable the tension bolts to support the formwork. BRIEF DESCRIPTION OF THE DRAWINGS
