As can be seen from the figure, the present utility model provides a double-layer glass curtain wall system based on a precast concrete frame, which is applied to the main building structure. The double-layer glass curtain wall system based on a precast concrete frame includes: a precast concrete frame 200, a first transparent curtain wall 210, and a second transparent curtain wall 220; the precast concrete frame 200 is provided on the main building structure, and an installation part is formed on the precast concrete frame 200; the first transparent curtain wall 210 and the second transparent curtain wall 220 are arranged at intervals in sequence from inside to outside, and the first transparent curtain wall 210 and the second transparent curtain wall 220 are respectively connected to the installation part.
[0030] In specific implementation, two transparent curtain walls are designed on the outside of the main building structure 100, namely the first transparent curtain wall 210 and the second transparent curtain wall 220, which are arranged in order from inside to outside. These two curtain walls are respectively connected to the installation parts on the precast concrete frame 200, jointly forming a double-layer structure. The innovation lies in that a precast concrete frame is used to replace the steel or aluminum alloy profiles in the prior art as the main structure of the building exterior wall. On the one hand, due to the strong thermal inertia of concrete, compared with steel or aluminum alloy profiles, it has better thermal performance, improving the heat insulation performance of the building; on the other hand, by using a precast concrete frame, precast concrete components can be manufactured in the factory, realizing unitized processing and manufacturing, and can achieve curved surface shapes that are difficult to accurately achieve with cast-in-place concrete. Moreover, the construction is relatively safe, and the quality and process of the produced components can be better controlled through mechanized production. At the same time, the dust and noise pollution at the construction site can be significantly reduced, and it can be combined according to different project situations (such as climate conditions, thermal control requirements, cost control, etc.), being flexible and variable to cope with different application scenarios; in addition, the precast concrete frame has architectural aesthetic advantages such as strong shaping ability, delicacy, and a sense of strength. At the same time, the double-layer curtain wall structure can also effectively reduce the impact of outdoor noise on the indoor environment, improve the comfort of living or use, and can also achieve the goal of reducing costs.
[0031] It can be understood that for the structures of the above-mentioned precast concrete frame 200, the first transparent curtain wall 210, and the second transparent curtain wall 220, they can be combined according to different project situations (such as climate conditions, thermal control requirements, cost control, etc.). For example:
[0032] 1. The first transparent curtain wall 210 adopts a sealed glass curtain wall, and the second transparent curtain wall 220 adopts an open glass curtain wall, that is, an external circulation double-layer curtain wall;
[0033] 2. The second transparent curtain wall 220 adopts sealed glass, and the first transparent curtain wall 210 is provided with operable windows, that is, an internal circulation double-layer curtain wall;
