Abstract
Description
Technical Field
[0001] This utility model relates to the field of building materials technology, specifically to an aluminum component for the eaves of a Chinese-style building. Background Technology
[0002] In traditional Chinese architecture, the eaves, as a crucial component of the building's exterior, not only serve the practical function of providing shelter from wind and rain but also embody rich cultural connotations and aesthetic value. The flying rafters, a key component of the eaves structure, are a core element in creating the flowing and dynamic curves of the eaves in traditional Chinese architecture, directly influencing the overall visual effect and spatial rhythm of the building. With the development of modern building technology, aluminum components, due to their lightweight, corrosion resistance, and excellent processing performance, have gradually become an important material choice for eaves components in traditional Chinese architecture. However, in practical applications, the precise adjustment of the angle of the flying rafters in aluminum eaves components faces numerous challenges.
[0003] In traditional Chinese architecture, determining the angle of the eaves rafters relies on experienced craftsmen who lay out the form on-site and make manual adjustments. This method is difficult to apply directly to aluminum components produced in industrialized environments. In industrialized production scenarios, existing techniques for adjusting the angle of eaves rafters mostly employ fixed-angle molds or pre-set angle connection structures, lacking a flexible adjustment mechanism.
[0004] When faced with the personalized requirements of different architectural designs for the angle of the eaves, or when the installation angle needs to be fine-tuned due to errors in the main building structure, these technologies often fall short of the requirements. In addition, due to the inherent properties of aluminum, problems such as component deformation and loosening of connections are prone to occur during the angle adjustment process, further increasing the difficulty of accurately adjusting the angle of the eaves and seriously restricting the development of diversified design and high-quality construction of aluminum components for the eaves of Chinese buildings. Utility Model Content
[0005] Technical problems to be solved
[0006] In view of the above-mentioned shortcomings of the existing technology, this utility model provides an aluminum component for the eaves of Chinese-style buildings, which can effectively solve the problems in the existing technology.
[0007] Technical solution
[0008] This utility model provides an aluminum component for the eaves of a Chinese-style building, including an eaves plate, a flying flange, and a connecting assembly for fixing the two. The connecting assembly includes side plates fixed to both sides of the top of the eaves plate, a limiting box fixed to the top of the eaves plate, and a rack set in the limiting box. The bottom end of the rack is engaged with a rotating tooth, the bottom end of the rotating tooth is fixedly connected to a base block, the middle part of the rotating tooth is fixedly connected to a rotating shaft, the two ends of the rotating shaft are set in the side plates, and the top end of the base block is fixedly connected to the flying flange.
[0009] Furthermore, a circular hole is provided on the top of the flange plate and the side wall of the limiting box, and a threaded rod is fitted inside the circular hole, and a nut is fitted on both the outer and inner sides of the threaded rod.
[0010] Furthermore, the cross-section of the rotating tooth is a semi-circular structure.

[0014] Beneficial effects
[0015] This invention, through its connecting component structure, allows users to fix the flange and flange plate together. Within the connecting component, users can pull the threaded rod to one side of the flange plate, thereby driving the rack structure to rotate the gears.
