Description

Technical Field

[0001] This invention relates to a support bracket conversion system and construction method for sloping wall construction. Background Technology

[0002] Hydraulic climbing integral steel platform formwork is a key piece of equipment for the construction of the core tube of high-rise buildings. During construction, when the core tube walls show a sloping inward taper, the formwork structure needs to be adapted to meet construction requirements. The bottom support brackets, which are the main load-bearing components, often interfere with the changing structure and need to be moved or reversed to adapt to the new support points.

[0003] The traditional on-site cutting and welding methods currently used have problems such as low construction efficiency, high safety risks, difficulty in guaranteeing welding quality, and damage to the main structure of the formwork. There is an urgent need for an innovative solution that can achieve rapid and safe conversion. Summary of the Invention

[0045] The support bracket device is installed on the bottom platform beam of the steel platform formwork, and the support bracket 1 of the support bracket conversion system extends out and supports the inclined wall at the corresponding height;

[0046] The hoisting and shifting device is installed on the lowest platform beam, such as the first platform beam 91, above the supporting bracket device, such as the second platform beam 92, to horizontally hoist the supporting bracket device to a position on the lowest platform beam further away from the inclined wall.

[0047] like Figures 1 to 5 As shown, in one embodiment of the support bracket conversion system for sloping wall construction of the present invention, it further includes:

[0048] The movable bottom beam 3 is connected to the supporting bracket device. The movable bottom beam 3 is provided with a first through slot. The bottom platform beam of the steel platform formwork is provided with a second through slot at positions from near to far from the inclined wall.

[0049] A through-type web plate connecting plate 4 passes through a first through slot and a second through slot at a corresponding position on the bottom platform beam to connect the movable bottom beam frame 3 to the bottom platform beam.

[0050] Here, the movable bottom beam 3 is a T-shaped structure made of H-beams, serving as the foundation for the movement and connection of the entire conversion system. First through slots are provided at corresponding positions on the upper and lower flanges of the movable bottom beam 3, and a second through slot is provided on the lowest platform beam. This allows the through-type web connecting plate 4 to quickly pass through the first and second through slots and be positioned, efficiently connecting the movable bottom beam 3 to the lowest platform beam at different locations.

[0053] Here, the supporting bracket device includes a supporting bracket 1, a hydraulic telescopic device 10, and an integrated reaction shell 2. The hydraulic telescopic device of the supporting bracket 1 is installed on the upper flange of the movable base beam 3, driving the supporting bracket 1 to extend and retract through the integrated reaction shell 2, thereby achieving separation from or support of the groove in the wall. The integrated reaction shell of the bracket is firmly connected to the front end plate of the movable base beam 3 by bolts to form a whole.

The positioning plate 8 has a threaded hole, and a positioning connecting bolt 11 is fitted inside the threaded hole for precise guidance and positioning of the connecting bolt 11. Through the telescopic movement of the telescopic device 7, the positioning connecting bolt 11 of the positioning plate 8 can be easily pushed into place and quickly fastened to the bottom platform beam.

[0063] In one embodiment of the support bracket conversion system for sloping wall section construction of the present invention, the hoisting and shifting device includes a sliding rail 12 and an electric crane 13.

[0064] Here, as Figure 6 As shown, a sliding rail is installed at the bottom of the second-layer platform beam 92 of the steel platform formwork, and an electric crane is mounted thereon.

[0066] Step S1, Preliminary preparation and installation: According to the tapering design of the sloping wall section, a second through slot is pre-set on the bottom platform beam of the steel platform formwork at a position from near to far from the sloping wall. By cooperating with the first through slot of the movable bottom beam frame, the movable bottom beam frame 3 and its supporting bracket device are pre-installed and connected in place.

[0067] Step S2, Install the hoisting system: Install a hoisting and shifting device on the platform beam of the upper level, such as the platform beam 92 of the second level, as shown below. Figure 7 As shown;

[0071] Step S6, Remove Interfering Components: Remove the platform beams and corresponding columns and walkway slabs on each floor that interfere with the subsequent formwork lifting and inclined wall section, such as... Figure 8 As shown.

[0072] Here, components that would collide with the sloping wall if the entire steel platform formwork were to be raised later are pre-removed. During this process, the steel platform formwork is supported on the concrete top surface by its own climbing guide rails at the top of the formwork.

[0073] Step S7, Remove Interference Components: After lifting the steel platform formwork and supporting bracket device to the height of one construction section using the climbing guide rail at the top of the steel platform formwork, support the supporting bracket in the reserved groove on the inclined wall section, such as...

[0075] This invention, through a collaborative design of "through-slot + rapid positioning device + hoisting rail," achieves modular rapid assembly, disassembly, and relocation of the corbel system, avoiding cumbersome cutting and welding and significantly shortening the construction period. The entire process requires no hot work, eliminating fire hazards. Mechanical connections ensure the continuity and stability of the load transfer path, effectively preventing major deformation of the formwork and significantly improving construction safety and structural reliability.
