[0007] Further, the anchor bar is L-shaped anchor bar. Of course, other shapes can also be designed.

[0008] Further, the anchor bar has three groups and is uniformly distributed on the bottom of square steel. Of course, other quantities can also be designed.

[0009] Further, the anchor bar is welded to the bottom of square steel. Of course, the anchor bar can also be fixed to the bottom of square steel in other forms.

[0010] Further, the cross section of the groove in the square steel is convex.

[0011] Further, the bolt set is composed of a T-shaped bolt, an inner nut, a gasket and an outer nut.

[0012] Compared with the prior art, the utility model has the advantages of: ① all components are assembled and combined, and there is no welding operation on site; ② simple structure and convenient installation; ③ components can be unified and modularized, and are processed in the factory and directly assembled on site; ④ manpower cost and material cost are saved; and ⑤ the device system is safer.

[0021] The technical scheme of the utility model will be described clearly and completely in combination with the drawings and embodiments. Obviously, the described embodiments are only part of the embodiments of the utility model, rather than all the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by those skilled in the art without creative labor belong to the protection scope of the utility model.

[0022] Refer to Figures 1 to 6 ​​​​A cantilever type outer scaffold H-beam lock device, comprising a groove type embedded part 1, an upper pressing plate 2 and a bolt set 3, the groove type embedded part 1 comprises anchoring ribs 11 and a square steel 12 with a groove on one side, the anchoring ribs 11 are fixedly connected to the bottom of the square steel 12, the upper pressing plate 2 is a rectangular steel plate with bolt holes at both ends, and the bolt set 3 is a T-shaped bolt set, the bolt set 3 has two groups, one end of which is clamped in the square steel 12, and the other end is assembled and connected with the upper pressing plate 2.

[0023] In the embodiment, the anchoring ribs 11 are L-shaped anchoring ribs. Of course, other shapes can also be designed.

[0024] In the embodiment, the anchoring ribs 11 are three groups and are uniformly distributed on the bottom of the square steel 12. Of course, other numbers of groups can also be designed.

[0025] In the embodiment, the anchoring ribs 11 are welded to the bottom of the square steel 12. Of course, the anchoring ribs 11 can also be fixed to the bottom of the square steel 12 in other forms.

[0026] In the embodiment, the groove in the square steel 12 has a convex cross section.

[0027] In the embodiment, the bolt set 3 is composed of a T-shaped bolt, an inner nut, a gasket and an outer nut. When installing the T-shaped bolt, the T-shaped bolt is first inserted longitudinally into the groove type embedded part 1, and then rotated by 90° to be clamped into the groove type embedded part.

[0028] Working principle:

[0029] First, the groove type embedded part 1 is pre-embedded in the floor to be poured, and the groove type embedded part 1 is filled with foam board during concrete pouring to prevent concrete from entering.

[0030] When installing the cantilever type outer scaffold H-beam 4 on the poured floor 5, the foam board filled in the groove type embedded part 1 is taken out, the T-shaped bolts of the two groups of bolt sets 3 are installed in the groove type embedded part 1 and located on both sides of the cantilever type outer scaffold H-beam 4, then the upper pressing plate 2 is installed on the cantilever type outer scaffold H-beam 4 and fastened through the inner nut, gasket and outer nut of the bolt set 3, wherein the upper pressing plate 2 presses the cantilever type outer scaffold H-beam 4, the upper pressing plate 2 transmits the overturning force of the cantilever type outer scaffold H-beam 4 to the bolt set 3, the bolt set 3 transmits the pulling force to the groove type embedded part 1, and the groove type embedded part 1 and the poured floor 5 jointly bear the force to ensure the safety and stability of the entire lock system.
