[0027] Among them, the core tube 1 includes a shear wall 11 and a reserved hole 12 set on the shear wall 11; the platform beam assembly 2 includes symmetrically arranged double channel steels 21, a channel steel crossbeam 22 connected between adjacent double channel steels 21, a foot-blocking channel steel 23 respectively connected to the bottom of each double channel steel 21 at both ends, a baffle 24 respectively connected to the bottom of each double channel steel 21 at both ends, a bracket spring 34 bearing 25 connected to the sides of the two ends of the double channel steel 21, a lifting ring 26 respectively connected to the top of each double channel steel 21 at both ends, and a platform circular hole 27 respectively connected to the side plates at both ends of each double channel steel 21 and located above the foot-blocking channel steel 23.

[0028] In this embodiment, the bracket assembly 3 includes a wedge-shaped bracket 31, a bracket round bar 32 connected to the wide end of the wedge-shaped bracket 31, a bracket nut 33 connected to the extended section of the bracket round bar 32, a bracket spring 34 connected to the bracket nut 33, and a bracket round hole 35 provided on the wedge-shaped bracket 31; the narrow end of the wedge-shaped bracket 31 is inserted into the reserved hole 12, and the wide end is inserted into the gap between the double channel steels 21 and is located above the baffle 24; the extended section of the bracket spring 34 is connected to the spring bearing 25.

[0029] In this embodiment, the length of the double channel steel 21 is set according to the size of the opening in the shear wall 11, and its length is 100 mm less than the length of the opening; the double channel steel 21 is composed of two symmetrical C-shaped members with a gap, and the size of the gap corresponds to the width of the wedge-shaped bracket 31; at least two groups of double channel steels 21 are provided in the core tube 1.

[0030] In this embodiment, the double channel steel 21 can be made by back-to-back welding of two 12# channel steels. Two platform round holes 27 are symmetrically provided at both ends of the channel steel for connecting with the bracket assembly 3. The length of the double channel steel 21 is about 100 mm less than the corresponding clear space in the core tube 1 to ensure free up-and-down movement in the core tube 1. A plurality of double channel steels 21 are arranged side by side in the core tube 1 according to the clear space. The horizontal spacing of the double channel steels 21 should not be greater than 2.0 m. Multiple double channel steels 21 are welded into an integral body through channel steel cross beams 22. There should be no less than two channel steel cross beams 22, and the horizontal spacing should not be greater than 2.0 m.

[0031] In this embodiment, the footrest channel steel 23 is a channel steel, which is respectively vertically connected to the lower part of each C-shaped member of the double channel steel 21; the internal angle formed by the footrest channel steel 23 and the wedge-shaped bracket 31 is clamped corresponding to the lower part of the reserved hole 12. The footrest channel steel 23 can be made of 12# channel steel, which is used to limit the horizontal position of the platform beam assembly 2 and prevent the bracket assembly 3 from sliding out of the reserved hole 12 in the core tube 1.

[0032] In this embodiment, the baffle 24 is connected to the bottom of the two C-shaped members. The baffle 24 is a steel plate and bears the wedge-shaped bracket 31. Two baffles 24 are symmetrically welded to the bottom of both ends of the double channel steel 21. The baffle 24 can be made of steel plate, which is used to limit the upward flipping of the wedge-shaped bracket 31 of the bracket assembly 3 and prevent the bracket assembly 3 from flipping upward and sliding out of the reserved hole 12 in the core tube 1.

[0033] In this embodiment, the spring bearing 25 is arranged between the two U-shaped members corresponding to the length of the spring and hooks the bracket spring 34; the lifting ring 26 is detachably connected to the lifting rope 5. Two spring bearings 25 are symmetrically welded on both sides of the double channel steel 21. The spring bearing 25 can be firmly welded to the web of the channel steel with round steel. One end of the bracket spring 34 of the bracket assembly 3 can hook the spring bearing 25; the lifting rope 5 is used to lift the platform device. Four lifting ropes 5 are in a group. One ends of the four lifting ropes 5 are respectively connected to the lifting rings 26 at the four corners of the platform device, and the other ends are connected to the hook of the hoisting machinery. The platform device is lifted by the hoisting machinery.

[0034] In this embodiment, the vertical section of the wedge-shaped bracket 31 is a right trapezoid. The narrow part is inserted into the reserved hole 12, and the wide part is detachably connected to the double channel steel 21; a bracket round bar 32 is fixedly connected to the center of the top of the wide part of the wedge-shaped bracket 31, and a bracket nut 33 is fixedly connected to the top of the outer extension end of the bracket round bar 32; the bracket nut 33 hooks the bracket spring 34. A bracket round hole 35 is also arranged in the middle of the long direction of the wedge-shaped bracket 31. The bracket round hole 35 corresponds to the platform round hole 27 and is connected through the bearing assembly 4.

[0035] In this embodiment, the bearing assembly 4 includes a bearing bolt 41 and a bearing nut 42 corresponding to the bearing bolt 41. The bearing bolt 41 correspondingly penetrates through the bracket round hole 35 and the platform round hole 27. The diameter of the bearing bolt 41 is slightly smaller than the diameters of the platform round hole 27 of the platform beam assembly 2 and the bracket round hole 35 of the bracket assembly 3 to ensure that it can freely penetrate. Under the action of an external force, the bracket assembly 3 can rotate downward around the bearing assembly 4 and the bracket spring 34 is stretched. When the external force is withdrawn, it can return to the horizontal state under the pulling force of the bracket spring 34.

[0036] When using the device, a hole 12 is reserved in the core tube 1 in advance, and the double channel steel 21, the channel steel beam 22 and other components are processed in advance according to the clearance size of the core tube 1 and the design requirements of the device; platform circular holes 27 are symmetrically opened at both ends of the double channel steel 21; then the spring bearing 25 is symmetrically welded between the two channel steels of the double channel steel 21; the channel steel beam 22 is welded to the double channel steel 21; the foot-blocking channel steel 23 is welded to the bottom of both ends of the double channel steel 21, and two baffles 24 are symmetrically welded at the bottom of both ends of the double channel steel 21; then the lifting rings 26 are symmetrically welded at both ends of the top of the channel steel on the inner side of the double channel steel 21, and the platform beam assembly 2 is now processed. When processing and manufacturing the corbel assembly 3, the wedge-shaped corbel 31 is processed according to the designed size, and the corbel round hole 35 is opened, and then the corbel round rod 32 is welded to the tail end of the wedge-shaped corbel 31, and the corbel nut 33 is welded to the other end of the corbel round rod 32, and then one end of the corbel spring 34 is hooked on the corbel nut 33. At this point, the processing and manufacturing of the corbel assembly 3 is completed. Afterwards, the device is organized at the construction site, and the platform beam assembly 2 is hoisted into the core tube 1 and placed horizontally by the lifting rope 5. Then, the platform beam assembly 2 and the corbel assembly 3 are connected into a whole through the bearing assembly 4. A corbel assembly 3 is installed at both ends of each double channel steel 21. The corbel assembly 3 is vertically placed between the two channel steels of the double channel steel 21, and the wedge-shaped corbel 31 is extended into the reserved hole 12 of the core tube 1. Then, the bearing bolt 41 is successively inserted into the platform circular hole 27 of the platform beam assembly 2 and the corbel circular hole 35 of the corbel assembly 3 and passed out, and then the bearing nut 42 is screwed in, and then the other end of the corbel spring 34 of the corbel assembly 3 is hooked on the spring bearing 25. At this point, the platform device is installed.

[0037] After that, a layer of operating frame can be set up on the platform device. After the main structure of the core tube 1 of this layer is completed, one end of the four lifting ropes 5 is connected to the lifting rings 26 at the four corners of the platform device, and the other end is connected to the hook of the lifting machinery. The platform device is lifted to the upper layer by the lifting machinery. During the lifting process, the wedge-shaped corbel 31 is gradually rotated downward and slides out of the reserved hole 12 under the squeezing action of the shear wall 11 of the core tube 1. At this time, the corbel spring 34 is in an elongated state. When it is lifted to the position of the reserved hole 12 of the core tube 1 of the upper layer, the wedge-shaped corbel 31 is pulled by the corbel spring 34. Rotate upward and extend into the reserved hole 12 of the upper core tube 1, then lower the platform device slightly, drop the wedge-shaped corbel 31 to the bottom of the reserved hole 12, and the corbel assembly 3 is in a horizontal state. Since a baffle 24 is provided at the lower end of the tail of the wedge-shaped corbel 31, the front end of the wedge-shaped corbel 31 is prevented from rotating upward and sliding out of the reserved hole 12. At this point, the platform device is lifted. During the lifting process of the platform device, the operating frame on the upper part does not need to be removed, and it is lifted together with the platform device. After the main structure construction of the upper core tube 1 is completed, continue the above operation to lift, and repeat the cycle. When removing the device after use, first remove the operating frame on the upper part of the device, then lift the device with the lifting rope 5, then remove the bearing assembly 4 and remove the corbel assembly 3, and finally slowly lower the platform beam assembly 2 to the floor with the lifting rope 5, then cut and separate the channel steel beam 22 and the double channel steel 21 and move them out of the core tube 1. The bracket assembly 3 and the bearing assembly 4 can be used cyclically, and the platform beam assembly 2 can also be used cyclically after adjustment.
