Detailed Implementation

[0024] To enable those skilled in the art to better understand the technical solution of this utility model, the technical solution of this utility model will be described below in conjunction with specific embodiments and accompanying drawings.

[0025] Modern architectural designs often feature high-altitude cantilever structures to achieve the desired effect of highlighting the building facade and expanding the upper space. However, the formwork support for high-altitude cantilever structures is challenging, and the quality and safety requirements are high. Conventional formwork support systems are often insufficient to meet the construction needs.

[0026] The scaffolding method of pre-embedding U-bolts to fix I-beams requires each I-beam to have its bolts pre-embedded individually. The hoisting and installation process is complicated, and the subsequent cutting of the channel steel and sealing of the wall openings will affect the construction progress of that floor and require a certain amount of labor.

[0027] If the height of the ground-supported scaffolding is too high, the cost will be too high, and the construction site of some high-rise buildings is too small to meet the site requirements.

[0028] like Figures 1-5 As shown, the technical solution in this embodiment allows for the fabrication of the external scaffold steel support before the main construction, and it can be directly hoisted and installed during construction at the cantilevered parts. Compared with the previous formwork support system, this saves a lot of construction time. Furthermore, the support frame is fixed by pre-embedded bolts in the external wall, which makes disassembly and assembly convenient and can greatly save the construction period.

[0029] This technical solution utilizes a basket-link cantilever scaffolding construction method, integrating the cantilever platform and scaffolding into a unified formwork support frame composed of multiple frame units. Before the main construction, BIM modeling is used to determine the steel profile parameters, and the prefabricated steel structure frame is constructed. First, the detailed parameters of individual I-beam supports are determined, and multiple individual I-beams are welded and fixed using anchoring steel plates to form the unified formwork support frame. Depending on the structural characteristics, each cantilever layer's formwork support frame can consist of several formwork support frames.

[0041] Embodiment 2

[0042] The same as embodiment 1 will not be described again, and the construction of the support platform is mainly described.

[0043] The parameters are determined, and detailed construction drawings are provided by the design unit. The detailed parameters of each overhanging layer are confirmed by the scaffold team, and the data required for the design of the steel structure formwork support frame is confirmed.

[0044] After confirming the data required for the steel structure formwork support frame, i.e. the support platform, the steel structure unit performs cutting and processing.

[0045] Confirm the processing parts, including pre-buried bolts, pre-buried lifting rings, pre-buried bolt hole I-beam end plates (anchor plates), I-beams (I-beam cantilever beams), I-beam pulling rods (pulling rods), and scaffold positioning piles (positioning piles).

They are mainly used to adjust the position between the anchor plate and the main body. In addition, a triangular support steel plate is added to the position where the I-beam is connected to the anchor plate to strengthen the firmness.

[0047] The position of the I-beam pulling point is determined according to the calculation, and a lifting lug steel plate (pulling lug) is welded at this position. The pulling lug is connected to the upper pulling plate at the end of the pulling rod by a pulling bolt.

[0054] After the support platform is processed, it is stored in the processing site. When the main body construction reaches the cantilever layer, use the tower crane or automobile crane to hoist the support platform to the construction layer and fix it, which can be used as a frame to set up the formwork support scaffold of the layer.

[0055] Based on the planar arrangement of I-beams, pre-embedding is carried out. Two Φ1.2cm round holes are opened on each cantilever beam on the outer formwork, and then the special screw is fixed on the outer formwork to ensure that the pre-embedded part does not deviate during concrete pouring.

[0056] When the concrete strength reaches more than 5MPa or the required strength, start installing the double-end screw.

[0059] Before pouring the concrete of the upper layer of the cantilever layer, arrange the pre-embedded part (150mm long) of the pull rod upper end pull-in point.

[0060] After the outer formwork is removed and the concrete strength reaches the specified requirement (generally about 48 hours after pouring), start twisting the pre-embedded lifting ring into the pre-embedded part and connecting the pull rod, and adjust it to the stressed state. Finally, set up the outer frame upwards to 20 meters (within).

[0061] Dismantling, after the outer wall construction is finished, hold force is hoisted by tower crane, and the support platform is dismantled.
