[0003] The applicant has discovered that the prior art has at least the following technical problems:

[0004] The current design of fire-resistant glass partition structures has flaws: 1. The lack of a direct and effective connection structure between the vertical frame and the horizontal frame results in insufficient structural strength and stability of the entire partition wall structure. The unstable frame structure not only reduces the stability of the overall structure, but may also cause the failure of the fireproof sealing material due to external forces, thereby affecting the fireproof performance of the fire-resistant glass partition wall. Moreover, due to the lack of a direct connection structure, the vertical frame and the horizontal frame need to be precisely aligned during installation, and multiple adjustments may be required. This places extremely high demands on the dimensional error at the construction site, making installation difficult and complex, and resulting in low installation efficiency.

[0005] 2. There is a lack of size adjustment mechanism between the fire-resistant glass and the frame. There is no room for adjustment during the installation process. Once the size deviates, it needs to be re-measured, cut or adjusted. It is extremely sensitive to dimensional errors at the construction site and requires high installation accuracy.

Based on the embodiments of the present invention, all other implementation methods obtained by ordinary technicians in this field without making any creative efforts are within the scope of protection of the present invention.

[0034] like Figures 1-6 As shown, the utility model provides a simple and quick-install double-layer fireproof glass partition structure, including a first horizontal frame 1, a second horizontal frame 2, a vertical frame 3, a connector 5 and a fireproof glass 4. The first horizontal frame 1, the vertical frame 3 and the second horizontal frame 2 are connected by a connector 5 to jointly enclose and form an accommodating space for the installation of the fireproof glass 4. The first floor keel 11 of the first horizontal frame 1 and the second floor keel 21 of the second horizontal frame 2 are respectively provided with horizontal plug-in grooves, and the vertical keel 31 of the vertical frame 3 is correspondingly provided with a vertical plug-in groove 311 that is compatible with the horizontal plug-in groove.
