AI Technical Summary
Existing fireproof and heat-insulating windows for cleanrooms have structural designs that make it difficult to center the slot, resulting in inconvenient connections. Furthermore, the sealant melts at high temperatures, causing the glass on the unexposed side to detach.
By designing an integrated structure for the fire-facing glass assembly and the central groove, a third sealant is used for sealing, and a second pressure block separates the fifth and sixth sealants, forming an integrated structure that isolates the sealant from the effects of high temperatures.
The centered placement of the slot ensures structural reliability and ease of connection, while protecting the sealant and preventing glass detachment caused by high-temperature melting, thus ensuring the window's airtightness and safety.

DETAILED DESCRIPTION
[0023] The utility model is further described below in combination with the drawings and specific embodiments.
[0024] Referring to Figure 1 , Figure 1 The upper side is the fire-facing surface, and the lower side is the backfire surface.
[0025] A clean room fireproof heat insulation window, comprising a fire-facing surface glass assembly, a backfire surface glass, and a steel keel; the fire-facing surface glass assembly has multiple layers of tempered glass, and a cavity between adjacent tempered glasses is filled with fireproof liquid 11; the steel keel comprises a Chinese character groove 3 and a first pressing block 4; the end of the innermost cavity is adjacent to the Chinese character groove 3 and the first pressing block 4, and a gap is provided between the Chinese character groove 3 and the first pressing block 4, which is filled with third sealant A3, and the third sealant A3 directly seals the cavity; the Chinese character groove 3 is centrally arranged in the thickness direction of the clean room fireproof heat insulation window.
[0026] In this embodiment, continuing to refer to Figure 1 , the steel keel further comprises a rectangular tube 8 and a second pressing block 5; one side of the rectangular tube 8 is fixedly attached to the first pressing block 1, and the other side is fixedly attached to the second pressing block 5; the second pressing block 5 is filled with sixth sealant A6 between the backfire surface glass, and the Chinese character groove 3 is filled with fifth sealant A5 between the second pressing block 5, so that the second pressing block 5 separates the sixth sealant A6 and the fifth sealant A5.
[0027] Fireproof heat insulation glass principle:
[0028] The fire-facing surface glass assembly forms two cavities by three layers of glass, and the middle is filled with "fireproof liquid". There are two kinds of fireproof liquid, one is grouting, and the other is nano silicon. The former has many problems such as liquid leakage and yellowing, and the latter can better avoid the above problems.
[0029] In the event of a fire, the first tempered glass shatters under high temperatures. The fire-retardant liquid in the first cavity expands upon contact with the fire, forming a foam-like substance that protects the second layer of glass. The fire-retardant liquid in the second cavity forms a hard plate that protects the third glass and the first pressure block, while also insulating it from high temperatures. It also provides protection and heat insulation for the portion formed by the central groove 3.
[0030] To achieve the 1-hour fire resistance and heat insulation requirement, the cavity between the three panes of glass needs to be 5 mm thick, plus the thickness of the three 5 mm panes of glass, totaling 25 mm. If used as an observation window in a cleanroom, the total thickness of the glass needs to be 50 mm, flush with both sides of the wall panel, and a centrally located U-shaped groove is required for connection to the two side wall panels (this is existing technology).
[0031] To achieve the above requirements, this utility model has made a special structural design for the second cavity, namely, the central part groove 3, the first pressure block 4 and three pieces of tempered glass together form multiple cavities, and the first, second, third and fourth sealants A1, A2, A3 and A4 form a seal.
[0032] The nano-silicon fireproof liquid is injected into the cavity and solidified after baking, so that the three tempered glass pieces, the central part groove 3 and the first pressure block 4 form a whole.
[0033] The rectangular tube 8 and the center slot 3 are welded (intermittent spot welding), and the second pressure block 5 is welded onto the rectangular tube 8 (intermittent spot welding). The glass on the back side can be fixed onto the second pressure block 5 with the sixth sealant A6 to form a complete cleanroom window.
[0034] There is a heat insulation pad between the rectangular tube 8 and the first pressure block 4, which prevents the temperature from being conducted to the second pressure block 5 through the rectangular tube, ensuring that the sixth sealant A6 will not melt due to high temperature, causing the innermost glass to fall off.
[0035] A gap is left between the second pressure block 5 and the center part groove 3 to ensure that the sixth sealant A6 will not melt due to high temperature, causing the innermost glass to fall off.
[0036] To ensure the cavity is airtight (otherwise, the glass inside will fog up under temperature differences), a fifth sealant A5 is used to seal the cavity. When the center slot 3 generates high temperature, the fifth sealant A5 will melt, but the sixth sealant A6 will not melt. At this time, the cavity loses its airtightness, preventing the high temperature and pressure from rupturing the sixth sealant A6 and causing the glass on the unexposed side to fall off.
[0037] In this embodiment, heat insulation pads are provided between the central character slot 3 and the first pressure block 4, between the rectangular tube 8 and the innermost fire-facing glass, and between the central character slot 3 and the second pressure block 5; a fourth sealant is provided between the first pressure block 4 and the innermost tempered glass of the fire-facing glass assembly, and the fourth sealant A4 seals the gap between the innermost tempered glass and the first pressure block 4.
[0038] In this embodiment, the second pressure block 5 has a first plane that abuts against the inner side of the unexposed glass, and a butyl rubber strip 6 is provided between the first plane and the unexposed glass.
[0039] In this embodiment, the second pressing block 5 also has a second plane perpendicular to the first plane, and a decorative strip 9 is attached to the outside of the second plane.
[0040] In this embodiment, the groove 3 of the Chinese character part is also provided with a fireproof expansion seal 2.
[0041] In this embodiment, the fire-facing glass assembly has three layers of tempered glass, which together form two cavities.
[0042] In this embodiment, support strips 12 are provided at both ends of the cavity. The outer side of the first support strip is sealed with a first sealant A1, and the outer side of the second support strip is sealed with a second sealant A2.
[0043] In this embodiment, the thickness of the cavity between adjacent tempered glass panes is 5mm, and the thickness of the tempered glass panes is 5mm, therefore the thickness of the fire-facing glass assembly is 25mm; the total thickness of the cleanroom fireproof and heat-insulating window is 50mm.
[0044] This invention designs the central character groove and the first pressure block as the innermost cavity adjacent to the fire-facing glass assembly (preferably, they can also be partially embedded in the cavity), and with the filling of the third sealant, the central character groove is centered in the thickness direction, ensuring structural reliability; the fire-facing glass assembly, the central character groove, and the first pressure block form an integrated whole, with high structural reliability; the second pressure block separates the fifth and sixth sealants, protecting the sixth sealant and isolating it from high temperatures (preventing the inner tempered glass from falling off due to high-temperature melting); the fifth sealant normally ensures the cavity is sealed, and melting at high temperatures causes the cavity to depressurize, thus essentially protecting the sixth sealant.
[0045] The above are preferred embodiments of the present utility model. Those skilled in the art can make their own modifications or improvements based on this. Without departing from the overall concept of the present utility model, these modifications or improvements should all fall within the scope of protection claimed by the present utility model.
