Description

Technical Field

[0001] This utility model relates to the field of building construction technology, and in particular to a cantilevered Bailey bridge support system and an external scaffolding reinforcement device. Background Technology

[0002] In the field of super high-rise building structural construction, cantilevered Bailey bridge support systems and external scaffolding reinforcement devices are key components for ensuring construction safety and quality. As an important temporary structure during construction, the stability of the cantilevered initial scaffolding directly affects the personal safety of construction workers and the smooth progress of the entire project.

[0003] In the traditional erection of conventional external scaffolding, outriggers are typically used for fixation. As a common and effective means of scaffolding reinforcement, outriggers provide lateral stability to the external scaffolding by forming a certain angle with the ground, enabling it to withstand various loads during construction and meet basic construction safety requirements.

[0004] However, with the continuous development of the construction industry, buildings with multiple zigzag lines, cantilevered structures, and diverse facade designs are becoming increasingly common. The large-span cantilevered locations of these buildings present new challenges for construction. In actual high-rise structure construction, due to constraints such as limited space above the cantilevered floor and complex site conditions, it is impossible to install bracing as required by specifications in many locations. For example, on some building facades with complex geometric shapes, other building components or equipment may exist above the cantilevered structure, occupying the space required for bracing; or the site terrain may be undulating, and the ground conditions may be unsuitable for the installation and fixing of bracing.

[0005] When outriggers cannot be installed, the initial scaffolding at large-span cantilever locations loses effective lateral support, making the scaffolding highly susceptible to swaying, displacement, or even overturning during construction, posing a significant safety hazard. This safety hazard not only endangers the lives of construction workers but may also lead to a series of problems such as project delays and quality degradation, making it impossible to meet the conditions for normal construction of cantilever structures.

[0030] Please see Figures 1-3 As shown, this utility model is a cantilevered Bailey bridge support system and external scaffolding reinforcement device, including an external scaffold 1, steel wire ropes 2, I-beams 3, Bailey bridges 4, cantilevered floor beams 5, and Bailey bridge anchor rings 6; wherein, the external scaffold 1 and the I-beams 3 are connected by cross-bracing of the steel wire ropes 2; the Bailey bridge 4 is fixedly installed on the cantilevered floor beams 5 through the Bailey bridge anchor rings 6, and the external scaffold 1 is designed with adjustable height to adapt to the construction of cantilever structures of different heights.

[0031] In an optional embodiment, the Bailey bridge anchor ring 6 includes a lower anchor ring 10 and an upper anchor ring 11. The Bailey bridge 4 is fixedly installed on the cantilever beam slab 5 through the lower anchor ring 10 and the upper anchor ring 11. By pre-embedding and welding the upper and lower anchor rings for reinforcement, a stable connection between the Bailey bridge and the cantilever beam slab is ensured, thereby improving the load-bearing capacity of the entire support system.

[0032] In an optional embodiment, the outer frame 1 and the I-beam 3 are connected by cross-bracing and fixing with the wire rope 2 using a “4+1” type of rope clamp 8. The “4+1” type of rope clamp fixing ensures the firmness and reliability of the wire rope connection and facilitates later inspection and maintenance.

[0033] In an optional embodiment, the I-beams 3 are evenly arranged on the Bailey bridge 4 as a support system for the construction of the outer scaffold 1 and the upper cantilever structure. The even arrangement of the I-beams provides uniform support force, ensuring the stability and safety of the outer scaffold and the upper structure.

[0034] In an optional embodiment, the Bailey bridge 4 is a prefabricated structure that facilitates quick installation and disassembly. The prefabricated structure improves construction efficiency, shortens the construction period, and facilitates transportation and storage.

[0035] In an optional embodiment, the wire rope 2 is provided with locking collars 7 at both ends. The locking collars 7 are sleeved on the I-beam 3 and the outer frame 1. The setting of the locking collars simplifies the connection process of the wire rope, improves the connection efficiency, and ensures the stability of the connection point.

[0036] In an optional embodiment, the cantilever beam slab 5 is provided with embedded parts for fixing the Bailey bridge anchor ring 6. The setting of the embedded parts ensures the stable installation of the Bailey bridge anchor ring and improves the stability and safety of the entire support system.

[0037] In an optional embodiment, the wire rope 2 is provided with a safety ring 9 for checking the tightness of the wire rope. The safety ring facilitates the subsequent inspection of the tightness of the wire rope and ensures safety during the construction process.

[0038] In an optional embodiment, a triangular reinforcing bracket 12 is provided between the Bailey bridge 4 and the cantilevered floor slab 5. The triangular reinforcing bracket further enhances the connection stability between the Bailey bridge and the cantilevered floor slab, and improves the wind pressure resistance and earthquake resistance of the entire support system.

[0039] In an optional embodiment, the cross-bracing connection of the wire rope 2 adopts a continuous cross-bracing method, and when the outer frame 1 is disassembled, the wire rope 2 is disassembled step by step from both sides to the middle.

[0040] The working principle of this utility model is as follows: In actual construction, the lower anchor ring 10 and upper anchor ring 11 of the Bailey bridge anchor ring 6 are first pre-embedded in the cantilever beam slab 5 and reinforced by welding with the side supports 12. Then, the Bailey bridge 4 is fixed to the cantilever beam slab 5 through the Bailey bridge anchor ring 6. Next, the I-beams 3 are evenly arranged on the Bailey bridge 4 as a support system for the construction of the outer scaffold 1 and the upper cantilever structure. Finally, the outer scaffold 1 and the I-beams 3 are cross-braced and fixedly connected by steel wire ropes 2 through "4+1" type rope clamps. Locking collars 7 are respectively sleeved at both ends of the steel wire rope, and safety rings 9 are set for later inspection of tightness.

[0041] After the entire construction is completed, the scaffolding is dismantled gradually from top to bottom, and the diagonal steel wire ropes are dismantled gradually from both sides to the middle. The dismantled steel wire ropes can be reused. The implementation of this utility model ensures the overall stability of the initial scaffolding, and also has the advantages of simple operation, strong practicality, convenient dismantling and reuse.

[0042] This utility model has few components, a simple structure, readily available materials, and is easy to manufacture. It solves the problem of areas where it is impossible to install bracing for reinforcement while ensuring the stability of the cantilevered scaffold and construction safety, and provides a certain reference for the construction of scaffolding in similar projects.
