[0002] In conventional scaffolding projects, the cantilever scaffolding is a commonly used scaffolding project. In the construction of high-rise buildings, due to construction requirements, different requirements for the load-bearing capacity of the cantilever scaffolding are also needed. Because of the particularity of the cantilever beam in the entire structural system, once quality problems occur, it will pose a great safety hazard to the entire building. Once cracks appear, they are very likely to further expand, and in severe cases, it will endanger the safety of the building. Therefore, it is very necessary to reinforce the cantilever beam.

Specific Embodiment

[0017] Next, the technical solutions of the present utility model will be clearly and completely described in conjunction with the embodiments. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all of the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative efforts shall fall within the protection scope of the present utility model.

[0018] Refer to Figures 1-4 , the present utility model provides a technical solution:

[0019] A reinforced and reusable cantilever device, comprising an I-beam 1 and angle steel plates 2. Bolt holes are provided on both side plates of the angle steel plates 2, and the bolt holes are equipped with matching expansion bolts. Among them, the diameter of the first expansion bolt 3 is larger than that of the second expansion bolt 4, and the diameter of the third expansion bolt 5 is larger than that of the fourth expansion bolt 6. In this embodiment, the bolt holes are arranged in two rows with two holes in each row, and the diameter of the first bolt hole 21 is larger than that of the second bolt hole 22; Bolt holes are also provided at corresponding positions on the I-beam 1 and the embedded part 13. The first expansion bolt 3 and the second expansion bolt 4 can fix the I-beam 1 and the angle steel plate 2 together, and the third expansion bolt 5 and the fourth expansion bolt 6 can fix the embedded part 13 and the angle steel plate 2 together. A branch rod 7 is also provided between the I-beam 1 and the embedded part 13. One end of the branch rod 7 is fixed to the I-beam 1 by bolts, and the other end is fixed to the embedded part 13 by bolts, which is used to further reinforce the connection between the I-beam 1 and the embedded part 13.

[0020] In this embodiment, the expansion bolts near the corners of the angle steel plates 2 have a larger diameter and can bear a greater weight to reinforce the connection between the I-beam 1 and the embedded part 13.

[0021] On both sides of the I-beam 1 on the embedded part 13, there are first hanging ear plates 81 fixed by bolts. Two first hanging ears 83 are provided on the first hanging ear plates 81. On the I-beam 1, second hanging ear plates 82 are provided corresponding to both sides of the first hanging ear plates 81 on the embedded part 13. Two second hanging ears are provided on the second hanging ear plates 82. A pull rod can be stretched between the first hanging ear plates 81 and the second hanging ear plates 82. The two ends of the pull rod are hooks 91, and the hooks 91 hook the hanging ears on the hanging ear plates to further strengthen the connection between the I-beam 1 and the embedded part 13.

[0022] In this embodiment, two hanging ears are provided on each hanging ear plate. A first pull rod 9 and a third pull rod 11 can be stretched on the upper side of the I-beam 1, and a second pull rod 10 and a fourth pull rod 12 can be stretched on the lower side of the I-beam 1. The number of pull rods is increased or decreased according to the load-bearing of the I-beam 1 to meet the requirements of the load-bearing capacity of the cantilever device during construction. When the load-bearing is small, the pull rods can be not hung, leaving more usable space on the I-beam 1; When the load-bearing increases, the second pull rod 10 and the fourth pull rod 12 are stretched to reinforce the connection between the I-beam 1 and the embedded part 13, increasing the load-bearing capacity of the cantilever device without reducing the usable space on the I-beam 1; When the load-bearing further increases, on the basis of stretching the second pull rod 10 and the fourth pull rod 12, the first pull rod 9 and the third pull rod 11 are stretched to increase the load-bearing capacity of the cantilever device and reinforce the cantilever device.

[0023] When the cantilever device is no longer used, the cantilever device is removed from the embedded part 13 and can be used for the next turnover.

[0024] The above are only the preferred embodiments of the present utility model. It should be understood that the present utility model is not limited to the form disclosed herein, should not be regarded as excluding other embodiments, but can be used in various other combinations, modifications and environments, and can be changed within the scope of the concept described herein through the above teachings or the techniques or knowledge in related fields.
