Detailed Implementation

[0022] The embodiments of this application will now be described in detail with reference to the accompanying drawings.

[0023] Example

[0024] Please refer to Figures 1-6 This embodiment provides a reusable prefabricated cantilever platform, including an I-beam main beam 1 and an I-beam diagonal support 2. The I-beam main beam 1 is horizontally arranged, and multiple fixing components are spaced along its length. The top of the I-beam diagonal support 2 is provided with a top mounting steel plate 3, which is horizontally arranged and detachably connected to the I-beam main beam 1. The bottom of the I-beam diagonal support 2 is provided with a bottom mounting steel plate 4, which has a first mounting through hole.

[0025] In some embodiments, there are two I-beam diagonal supports 2, one with a horizontally mounted bottom steel plate 4 and the other with a vertically mounted bottom steel plate 4. It also includes a first mounting bolt 5 and a first mounting nut 6. The first mounting bolt 5 passes through the top mounting steel plate 3 and is threaded onto the I-beam main beam 1, and is connected to the first mounting nut 6. The first mounting bolt 5 and the first mounting nut 6 facilitate the fixing of the top mounting steel plate 3 to the I-beam main beam 1 and also facilitate the removal of the top mounting steel plate 3 from the I-beam main beam 1, making operation convenient.

[0026] In actual use, the fixing components can be pre-embedded in the main building structure during construction. For the bottom steel plate 4, which needs to be installed at the required location, vertical bolts 13 are pre-embedded in the main building structure for horizontally installed bottom steel plates 4, and horizontal pre-embedded sleeves are pre-embedded in the main building structure for vertically installed bottom steel plates 4. During the installation of the cantilever platform, the I-beam main beam 1 is fixed using various fixing components, such as... Figure 4As shown, the top of the I-beam diagonal support 2 is fixed to the I-beam main beam 1 by the first mounting bolt 5 and the first mounting nut 6; Figure 3 As shown, the vertical bolt 13 passes through the first mounting through hole of the horizontally set bottom mounting steel plate 4 and is threadedly connected to the nut. The mounting screw 14 passes through the pre-embedded sleeve and the first mounting through hole of the vertically set bottom mounting steel plate 4. Both ends of the mounting screw 14 are threadedly connected to the nut. At this time, the bottom of the I-beam diagonal support 2 can be fixed to the main building. After the cantilever platform is installed, a support frame 15 can be set on the top of the cantilever platform.

[0027] In this application, the reusable prefabricated cantilever platform is constructed with pre-embedded parts reserved in the outward-protruding cantilever structure of the refuge floor. Construction of the outward-protruding cantilever structure is carried out after the climbing scaffold is lifted, resolving the conflict between the outward-protruding cantilever structure of the refuge floor and the climbing scaffold lifting process. The cantilever platform, assembled using detachable prefabricated I-beam main beams 1 and I-beam diagonal supports 2, ensures the load-bearing capacity and stability of the support system. Simultaneously, the support materials between buildings can be reused, installed, and disassembled, saving construction time and material rental costs.

[0028] like Figure 1 , Figure 2 and Figure 5 As shown, in some embodiments, the fixing component includes a U-shaped retaining ring 7 and an angle steel 8. Both ends of the U-shaped retaining ring 7 are detachably connected to the angle steel 8, and the I-beam main beam 1 passes through the U-shaped retaining ring 7. Each U-shaped retaining ring 7 is provided with two second mounting nuts 9. Both ends of the U-shaped retaining ring 7 are provided with external threads, and both ends of the U-shaped retaining ring 7 pass through the angle steel 8 and are threadedly connected to the second mounting nuts 9.

[0029] During construction, the U-shaped retaining ring 7 is first embedded in the main body of the building. When installing the I-beam main beam 1, after the I-beam main beam 1 passes through the U-shaped retaining ring 7, both ends of the U-shaped retaining ring 7 pass through the angle steel 8 and are threadedly connected to the second mounting nut 9. At this time, the I-beam main beam 1 can be fixed to the main body of the building through the U-shaped retaining ring 7 and the angle steel 8. The operation is convenient and it is also convenient to disassemble the I-beam main beam 1 later.

[0030] like Figure 1 , Figure 2 and Figure 6 As shown, in some embodiments, a steel wire rope 10 is also included. One end of the steel wire rope 10 is connected to the I-beam main beam 1, and the other end of the steel wire rope 10 is provided with a steel wire rope pull ring 11. By setting the steel wire rope 10, the steel wire rope pull ring 11 is pre-embedded in the main structure of the building during construction. After the I-beam main beam 1 is installed, the bottom end of the steel wire rope 10 can be connected to the I-beam main beam 1, and the top end of the steel wire rope 10 is connected to the pre-embedded steel wire rope pull ring 11. In this way, the steel wire rope 10 is used to pull the I-beam main beam 1, which further improves the load-bearing capacity and stability of the cantilever platform.

[0031] like Figure 6 As shown, in some embodiments, the wire rope pull ring 11 is U-shaped, and both ends of the wire rope pull ring 11 are provided with bending portions 12. By providing bending portions 12, which are pre-embedded into the building structure, this utility model can improve the installation stability of the wire rope pull ring 11.

[0032] Furthermore, unless otherwise explicitly specified or limited, the terms "installation" and "connection" in this application embodiment should be interpreted broadly. For example, "connection" can be a detachable connection or a non-detachable connection; it can be a direct connection or an indirect connection through an intermediate medium. The terms "upper," "lower," "left," "right," "inner," "outer," and "side," etc., are merely for reference to the direction in the accompanying drawings or the usual placement of the product during use. They are only for clearly describing this application and do not indicate or imply that the device or component referred to must have a specific orientation, or be constructed and operated in a specific orientation. They should not be construed as limitations on this application. The terms "first," "second," etc., are only used for distinguishing descriptions and should not be construed as indicating or implying relative importance; "multiple" refers to at least two. In this application embodiment, the limitations on relative positional relationships such as parallel, perpendicular, and aligned are all relative to the current technological level and are not absolutely strict limitations. Slight deviations are allowed; approximations of parallel, perpendicular, and aligned are all acceptable. For example, "A and B are parallel" means that A and B are parallel or approximately parallel, and the angle between A and B can be between 0 degrees and 10 degrees.

[0033] The above are only some embodiments and implementation methods of this application. The protection scope of this application is not limited thereto. In the absence of conflict, the embodiments and features in the embodiments of this application can be combined with each other. Any combination of features in different embodiments is also within the protection scope of this application.
