[0002] At present, unit window curtain walls have been widely used in high-rise buildings. A unit window curtain wall is to install unit window panels between the interlayer main structures (concrete structures) of upper and lower floors, and between adjacent upper and lower unit window panels, according to fireproof requirements, a fireproof structure is set on the interlayer main structure, and the fireproof structure is usually designed on the window sill wall. However, with the continuous improvement of people's requirements for the transparency of curtain walls, nowadays many unit window curtain walls do not design a window sill wall on the interlayer main structure, or the designed window sill wall is not high enough to meet the fireproof requirements. In view of this situation, the existing method is to continue constructing a window sill wall on the interlayer main structure, with its height as low as possible, and then carry out fireproofing. But the resulting disadvantages are that the construction procedures are invisibly increased, the construction cost is increased, the construction period is prolonged, and the transparency originally intended for the curtain wall is greatly reduced.

[0019] In addition, a horizontal aluminum profile 123 can also be installed outside the steel cross beam 111 on the outer end face of the framework, that is, in actual application, the above-mentioned framework installs aluminum profiles at appropriate positions on its outer periphery according to requirements, such as Figure 3 .

[0020] As Figure 1 and Figure 2 shown, embedded parts 50 are provided on the interlayer main structure 90, the embedded parts 50 are connected to L-shaped aluminum adapter parts 60, positioning bolt assemblies 70 are installed on the L-shaped aluminum adapter parts 60, and the cornice unit 10 is hung on the positioning bolt assemblies 70 through the L-shaped hanging grooves 1280 on the steel hanging parts 128 to achieve hanging connection on the interlayer main structure 90.

[0021] Furthermore, the L-shaped aluminum adapter 60 is composed of two aluminum plates. One aluminum plate is connected to the embedded part 50, and the other aluminum plate is connected to the positioning bolt assembly 70.

[0022] The embedded part 50 usually includes an embedded groove embedded on the outdoor side of the interlayer main structure 90. An embedded bolt is movably installed in the embedded groove, and an embedded nut is screwed on the part of the embedded bolt exposed from the interlayer main structure 90.
