[0002] In existing technology, the core tube construction of super-high-rise buildings generally uses an integrally hoisted steel platform and an internally climbing tower crane as the primary construction equipment. These devices are typically installed within the elevator shaft of the core tube, with the internally climbing tower crane's support steel beam located below the integrally hoisted steel platform. As the main building construction progresses, both devices must rise synchronously. However, the vertical distance between them varies at different stages of construction.

[0003] The traditional hanging operating platform cannot ensure the appropriate distance between the two devices, the integral lifting steel platform and the internal climbing tower crane. The Chinese utility model patent with the authorization announcement number CN217076789U discloses a tower crane-attached hanging operating platform. The hanging operating platform is used to detachably install the operating platform on one side of the tower crane standard section through a plurality of connecting parts. Although the structure can be reused, the height of the hanging operating platform cannot be adjusted according to construction needs and actual conditions. It is not suitable for processing walls of different heights during the construction of the core tube of a super high-rise building. Therefore, there is an urgent need to develop an adjustable assembled hanging operating platform for the construction of the core tube of a super high-rise building. Utility Model Content

DETAILED DESCRIPTION

[0026] To make the above-mentioned objects, features, and advantages of the present invention more clearly understood, the following detailed description of the specific embodiments of the present invention is provided in conjunction with the accompanying drawings. The following description sets forth many specific details to facilitate a full understanding of the present invention. However, the present invention can be implemented in many other ways than those described herein, and those skilled in the art can make similar improvements without violating the scope of the present invention. Therefore, the present invention is not limited to the specific embodiments disclosed below. The technical features of the various embodiments of the present invention may be combined accordingly, provided that there is no conflict between them.

[0027] like Figure 1As shown in FIG. 1 , as a preferred embodiment of this embodiment, this embodiment provides an adjustable assembled lower-hanging operating platform, comprising a connecting beam 1, a lifting device 2, and an operating platform, wherein the operating platform comprises a supporting main beam 3, a supporting secondary beam 4, a second walkway plate 6, and a connecting rope 12. The connecting beam 1 and the supporting main beam 3 are provided in at least two groups, and the size and number of the lifting device 2 and the supporting secondary beam 4 can be adjusted according to actual construction requirements.

[0028] In the device provided by the present utility model, Figure 2 As shown, each connecting beam 1 consists of two connecting channel steels with openings facing opposite each other. The webs of the connecting channels are spaced parallel and connected. The two connecting channels are fixedly connected by a connecting plate, which is welded to the ends of the webs of the two connecting channels. Several connecting beam clamps 8 with connecting holes are fixed between the lower flanges of the two connecting channels. First connecting rods 9 pass through the holes in the connecting beam clamps 8 to connect to the superstructure. In this embodiment, two connecting beam clamps 8 are provided, which, together with the first connecting rods 9, securely connect the connecting beam 1 to the superstructure, providing a certain degree of support. The webs of the two connecting channels have several connecting holes for the first attachment bolts 10, with the holes in the two webs aligned. The ends of the first attachment bolts 10 pass perpendicularly through the two webs and are secured to the connecting beam 1 using nuts that match the first attachment bolts 10. The first attachment bolts 9 can be screws or other similar fasteners.

[0029] like Figure 3 As shown, the hook at the top of the lifting device 2 is attached to the first attachment bolt 10 on the connecting beam 1, and the other end of the lifting device 2 is fixedly connected to the operating platform below. A hand chain hoist has a simple structure and is lightweight. It does not require complex operating procedures and can be lifted simply by pulling. Compared to electric hoists or other mechanical lifting equipment, hand chain hoists are less expensive and are suitable for projects with limited budgets or small-scale engineering. Therefore, in this embodiment, a hand chain hoist is used as the lifting device 2. Of course, those skilled in the art can also choose an electric hoist or other mechanical lifting equipment according to actual working conditions.

[0030] like Figure 4 and Figure 5As shown, the main support beams 3 are arranged parallel to the connecting beams 1. Each set of main support beams 3 includes two support channels with openings in opposite directions. The webs of the support channels are spaced apart and parallel to each other. The two support channels are fixedly connected by a connecting plate, which is welded to the ends of the webs of the two support channels. Several secondary support beams 4 are laid on the upper surface of the main support beams 3. The secondary support beams 4 are arranged perpendicular to the main support beams 3. In this embodiment, two secondary support beams 4 are used. In other embodiments, the number of secondary support beams 4 can be increased according to the construction requirements to improve the load-bearing capacity of the operating platform. The secondary support beams 4 can be made of square steel tubes, channel steel, or I-beams.

[0031] Several supporting main beam clamps 13 with connecting holes are fixed between the lower flanges of the two supporting channel steels. Second connecting rods 14 pass through the connecting holes in the supporting main beam clamps 13 to securely connect to the supporting secondary beam 4 above. In this embodiment, two supporting main beam clamps 13 are provided, working together with the second connecting rods 14 to secure the supporting main beam 3 and the supporting secondary beam 4 together. The second connecting rods 14 can be screws or other equivalent fasteners. The webs of the two supporting channel steels are provided with several connecting holes for the second attachment bolts 15, with the holes on the two webs aligned. The ends of the second attachment bolts 15 pass perpendicularly through the two webs and are secured to the supporting main beam 3 using matching nuts. Connecting ropes 12 are provided at both ends of the supporting main beam 3. One end of the connecting rope 12 is attached to the second attachment bolt 15, and the other end is connected to the lifting device 2. Due to the heavy weight of the operating platform, and for safety and frictional considerations, the connecting ropes 12 in this embodiment are steel wire ropes.

[0032] To facilitate the movement of construction workers during construction, several second walkway panels 6 are closely laid on the supporting secondary beam 4. These second walkway panels 6 are conventional. Since connecting ropes 12 are installed at both ends of the supporting main beam 3, to expand the range of movement for construction workers and facilitate the installation of the connecting ropes 12, first walkway panels 5 with holes at both ends are installed on either side of the second walkway panels 6 where the connecting ropes 12 are installed. The connecting ropes 12 pass through the holes at both ends of the first walkway panels 5 and connect to the lifting device 2. The several second walkway panels 6 are fixed to each other and to the first walkway panels 5 on either side via fixings 11. To allow for material recycling, rivets are used in this embodiment to achieve the fixings 11. This allows for flexible installation and removal of the device, facilitating ease of use and reducing construction costs. In other embodiments, the several second walkway panels 6 and the second walkway panels 6 and the first walkway panels 5 on either side can also be connected using screws or other removable means. To ensure the personal safety of construction workers and prevent them from accidentally falling during operation, several safety ropes 7 are also installed between the connecting beam 1 and the operating platform.

[0033] The above-described embodiment is merely a preferred embodiment of the present invention and is not intended to limit the present invention. Persons skilled in the art may make various changes and modifications without departing from the spirit and scope of the present invention. Therefore, any technical solution obtained by equivalent substitution or equivalent transformation falls within the scope of protection of the present invention.
