Description

Technical Field

[0001] This utility model relates to the field of building structure technology, specifically a high-altitude cantilever structure. Background Technology

[0002] High-altitude cantilever structures are a type of structure used in building construction. In terms of location, they are usually located at a high position in the building and cantilever outwards. For example, they may be used on the observation decks of some high-rise buildings, the exterior decoration of large shopping malls, or the eaves of the roof of stadiums. In terms of structural composition, they mainly include cantilever slab components, support components, and other parts.

[0003] Cantilever slabs can be made of materials such as concrete slabs or metal slabs to bear external loads. Support components are used to fix the cantilever slabs and ensure their stability. Their stress characteristics are relatively complex. On the one hand, they must bear their own weight, and on the other hand, they must bear external forces such as wind loads and personnel activity loads. Therefore, many factors need to be considered in the design and construction process, such as the strength of materials, the stiffness and stability of the structure, to ensure the safety and reliability of the structure.

[0004] The common method for erecting formwork scaffolding for high-altitude reinforced concrete cantilever structures is as follows: the uprights of the formwork scaffolding for the cantilever structure rest on the cantilevered I-beams, and the lower part of the cantilevered I-beams is further supported by steel sections at an angle. The cantilevered I-beams are welded to the inclined steel sections below.

[0005] Chinese Utility Model Patent Publication No. CN219622264U discloses a high-altitude cantilever formwork structure. This structure uses a rotating ring that can rotate along a fixed axis to achieve multi-angle fixation with cables. The rotating ring can adjust its position according to the cable angle, facilitating cable installation. Furthermore, the force direction of the ring is always along the extension direction of the cable, resulting in good fixation. However, it does not improve the cable connection points, which can easily lead to damage at the cable connections after prolonged use. In addition, this high-altitude cantilever formwork structure cannot reduce the number of cables used or lower the operating cost. Summary of the Invention

[0006] The technical problem to be solved by this utility model is to provide a high-altitude cantilever structure that can effectively solve the problems in the prior art.

[0007] The technical solution adopted by this utility model is: a high-altitude cantilever structure, including a floor slab and a plug-in type load-bearing rod, as well as a first cantilever plate assembly and a second cantilever plate assembly located outside the floor slab. An I-beam fixing member is provided between the plug-in type load-bearing rod and the floor slab to fix the plug-in type load-bearing rod. An I-beam load-bearing rod is provided on the side of the plug-in type load-bearing rod away from the floor slab. A load-bearing rod plug-in ring is provided on the side of the I-beam load-bearing rod close to the plug-in type load-bearing rod. An adapter block is fixedly installed at the top of the inner side of the load-bearing rod plug-in ring.

[0010] Through the above technical solution, the suspension alignment support block can be quickly inserted and installed in the alignment groove. At the same time, the locking bolt can securely lock the suspension alignment support block to the I-beam load-bearing rod.

A connector is provided on the outer side of the upper hanging lug, and a lower hanging lug is provided on the outer side of the connector. A connecting block is provided on the side of the anchor point support plate away from the floor slab, and a steel cable connector is provided on the side of the connecting block away from the anchor point support plate.

The transverse inner support rod and the longitudinal inner support rod are staggered. The structure of the first cantilever plate assembly is the same as that of the second cantilever plate assembly.

[0015] Through the above technical solution, the staggered distribution of transverse and longitudinal inner support rods can provide better support and improve the strength of the cantilever slab assembly.

Then, the first steel cable 10 and the second steel cable 13 are connected to the suspension support assembly 9 at the bottom of the first cantilever slab assembly 14 and the suspension support assembly 9 at the bottom of the second cantilever slab assembly 16, respectively. Finally, the workers place the first cantilever slab assembly 14 and the second cantilever slab assembly 16 between the multiple I-beam load-bearing rods 5 and then tighten them with bolts to complete the installation.
