Description

Technical Field

[0001] The present invention relates to the technical field of building curtain walls, and in particular to an integrated all-aluminum profile high aspect ratio opening window system and an installation method thereof. Background Art

[0002] With the development of building curtain wall technology, curtain walls not only need to ensure the lighting and ventilation needs of buildings, but also need to take into account the building facade modeling and decoration requirements. Therefore, the glass curtain wall + aluminum opening sash system has gradually been used due to its strong decorative, light weight, good corrosion resistance and other characteristics. However, in the current curtain wall aluminum opening windows, the window sashes are mostly multi-layer laminated structures composed of multiple materials from the surface to the inside, and the assembly of window sashes and window frames requires the use of corner extrusion machines for semi-finished product assembly.

[0003] This multi-layer laminated structure and semi-finished product assembly method brings two significant disadvantages to the installation and molding of window sashes. On the one hand, the errors in splicing multiple materials affect the appearance and decorative effects; on the other hand, the assembly requires multiple processing steps, and the construction is not efficient and convenient enough.

[0004] In particular, under the laminated structure, the outermost decorative aluminum veneer and aluminum alloy sash frame are usually fixed with countersunk bolts and structural adhesive. The structural adhesive connection makes it difficult to control the smoothness of the finished surface of the aluminum veneer. In addition, when the area of ​​the decorative aluminum veneer is slightly larger, it is easy to bend and deform. The slight bending deformation plus the influence of the external temperature and other environments will produce stress deformation, which will cause the edges of the bonding surface to crack and warp easily, resulting in poor appearance after molding, and low reliability and durability of the connection. The bolt fixing method leads to too much window sash processing and material parts, and affects the integrity and aesthetics of the finished surface. In addition, the on-site process is complicated, the semi-finished product assembly method of the material and the processing and cutting accuracy of the decorative aluminum veneer are limited, and the construction is not efficient and convenient. All these make the appearance and decorative effect of the aluminum plate opening window after completion not guaranteed. Summary of the invention
