Description

[0002] As the curtain wall industry in China becomes more and more mature, various forms of curtain wall systems emerge one after another. Among them, the unitized curtain wall has always occupied the leading position in the curtain wall system solution due to its convenient and quick installation and excellent waterproof performance, and is deeply trusted by experts and owners. Figure 1 As shown, in the unitized curtain wall system, the commonly used floor code 10 for hanging the wall node is a plate structure. However, as the building height is getting higher and higher, the weight of the unit body plate 20 is also getting heavier, and the construction deviation of the on-site concrete is difficult to avoid, which can easily cause the bearing point of the floor code 10 to be far away from the edge of the concrete, thereby increasing the deformation of the floor code 10, and thus requiring the thickness of the floor code 10 to be larger and larger. The increase in the thickness of the floor code 10 is likely to bring a safety problem: when processing thicker floor codes (14mm and above), due to the uneven cooling of the aluminum liquid, the internal structure of the floor code will cause structural defects, seriously affecting the safety of use.
