Description

Technical Field

[0001] The present invention belongs to the technical field of building construction, and particularly relates to a method for reserving wall-piercing embedded part holes for steel-aluminum formworks of high-rise buildings. Background Art

[0002] At present, during the pouring of super high-rise buildings in China, wall-piercing embedded part holes need to be reserved in advance for the exterior wall. However, when the climbing formwork and climbing frame used for super high-rise buildings are both equipped with steel formworks for the exterior wall pouring operation, the PVC pipes for the reserved holes in the exterior wall will be misaligned during the concrete pouring, resulting in the misalignment of the exterior wall bolts, and further affecting the stability of the overall structure.

[0003] The existing solution is to drill holes in the steel formwork placed on the exterior wall and the aluminum formwork placed on the interior wall to place the PVC pipes. However, this method will cause leakage when the aluminum formwork and the steel formwork reach the non-standard floors after use, and the steel formwork and the aluminum formwork need to be repaired later, which is not worth the loss. In addition to this method, no other effective methods have been found in the industry. For a simple shear wall structure, the deviation of individual exterior wall bolts has little impact on the integrity of the structure. However, for super high-rise buildings, the deviation of a large number of wall bolts will have a greater impact on the overall super high-rise building. Summary of the Invention

[0029] As Figure 2 , Figure 3 and Figure 6 shown, the reserved hole support mechanism includes a metal bellows 3 and an internal support component. The two ends of the metal bellows 3 respectively cooperate with the clamping blocks 6 on the side of the steel mold 1 and the clamping blocks 6 on the side of the aluminum mold 2, and the two ends of the internal support component respectively cooperate with the first groove on the side of the steel mold 1 and the first groove on the side of the aluminum mold 2.

[0030] As Figure 7 and Figure 8 shown, the internal support component includes a plurality of support groups, which are fixedly connected in sequence, and the ends of the support groups at both ends are both installed with a first protrusion 12, and the first protrusion 12 cooperates with the first groove.

[0031] As Figure 7 and Figure 8 shown, each of the plurality of support groups includes a first connecting disk 11 and a second connecting disk 13. A connecting shaft is installed between the first connecting disk 11 and the second connecting disk 13.
