Description

Technical Field

[0001] This utility model relates to the field of fire-resistant window technology, and in particular to a fire-resistant window with explosion-proof function. Background Technology

[0002] When storing hazardous materials, they must be placed in a separate warehouse made of explosion-proof and fire-resistant materials, and the windows of the warehouse must be fire-resistant windows with explosion-proof properties.

[0003] However, most existing fire-resistant windows are supported by tempered glass. When hazardous materials inside the warehouse explode, the resulting shock wave impacts the window, causing it to deform to some extent. This creates gaps between the window and the glass, allowing flames and toxic gases inside the warehouse to leak to the outside, making them inconvenient to use. To address this issue, we propose a fire-resistant window with explosion-proof function. Utility Model Content

[0004] The purpose of this utility model is to address the shortcomings of existing technologies mentioned in the background section by proposing a fire-resistant window with explosion-proof function.

[0007] The sealing component can seal the gap between the window frame and the window sash by pressing, thereby preventing the leakage of toxic gases after the window frame or window sash is deformed.

[0008] Preferably, the sealing assembly includes a fixed silicone strip, a graphite-based expansion sealing strip, and an airtight pressure strip;

[0009] The graphite-based expansion sealing strip expands when heated, filling the deformed gaps and improving the sealing effect between the window frame and the window sash.

[0010] Preferably, a locking handle is provided on the front of the window sash;

[0011] The window sash can be locked and opened by turning the locking handle.

[0014] Preferably, a glass mounting groove is provided on the back of the window sash, and the diameter of the glass mounting groove is larger than the inner wall diameter of the window sash;

[0015] High-temperature resistant tempered glass can be placed inside the glass mounting groove for installation.

[0016] Preferably, a fixing baffle is provided on the back of the window sash, and the shape of the fixing baffle is adapted to the glass mounting groove;

[0017] The glass can be positioned after installation by using a fixed baffle, which makes the installation of the glass more stable.

[0018] Preferably, the interior of the window frame body and the window sash is filled with an explosion-proof layer and a fire-resistant layer. The explosion-proof layer includes steel wire mesh and polycarbonate board, while the fire-resistant layer includes ceramic fiber board and a flame-retardant coating applied to the surface of the ceramic fiber board.

[0019] It can improve the strength of the window frame and sash, thus improving the explosion-proof effect.

[0020] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0021] 1. This utility model can press the sealing component into the groove, so that when it is subjected to an explosive impact, the sealing component will expand when heated, which can fill the gap between the window frame body and the window sash caused by the impact deformation, thereby completing the seal between the window frame body and the window sash, preventing toxic fumes and open flames from escaping to the outside world, and increasing the safety factor.

[0022] 2. This utility model installs an explosion-proof layer and a fire-resistant layer inside the window frame body and window sash, which improves the strength of the window frame body and window sash, thereby enabling the window frame body and window sash to better resist impact and thus improve the deformation resistance of the window frame body and window sash. After use, only the sealing components need to be replaced for reuse, saving usage costs. Attached Figure Description

[0028] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0029] Reference Figure 1-4 The fire-resistant window with explosion-proof function shown has mounting holes around the window frame body 1, which can be fixed to the window with bolts. Then, the window sash 2 is placed inside the window frame body 1. The back side of the window sash 2 has a mounting groove 6. Then, a rotating hinge 7 is fixed to the mounting groove 6 with bolts. The other end of the rotating hinge 7 is fixed to the inner wall of the window frame body 1 with bolts, so that the window sash 2 can rotate inside the window frame body 1. The window sash 2 is vacuum-sealed, and glass can be installed in the middle position of the window sash 2. A glass mounting groove 8 is formed on the back of the window sash 2. The area of ​​the glass mounting groove 8 is larger than that of the middle position of the window sash 2. The area of ​​the window frame allows the glass to be placed inside the glass mounting groove 8. A fixing baffle 9, which is compatible with the glass mounting groove 8, is then installed on the outside of the glass mounting groove 8. The side wall of the fixing baffle 9 can position the glass inside the glass mounting groove 8. The baffle 9 is then fixedly connected to the inner side wall of the glass mounting groove 8 of the window sash 2 by bolts. At the same time, a fixing silicone strip is fixed on the side of the glass mounting groove 8 and the fixing baffle 9 that is in contact with the glass, which can position the glass and provide sound insulation. The main body of the window frame 1 is made of double-layer cold-formed steel profile and filled with fireproof rock wool. The window sash 2 is a multi-layer composite frame with an outer aluminum alloy edging and an inner explosion-proof layer and a fire-resistant layer.

[0030] Specifically, the explosion-proof layer and the fire-resistant layer are described. The explosion-proof layer is composed of a high-strength steel wire mesh and a polycarbonate board. The steel wire mesh has a mesh size of 5mm and is fixed to the inside of the window sash with bolts to disperse the impact force of an explosion. The fire-resistant layer includes a ceramic fiber board and an intumescent flame-retardant coating. The ceramic fiber board is 20mm thick and is attached to the inside of the explosion-proof layer. The flame-retardant coating is applied to the contact surface between the window frame body 1 and the window sash 2. When exposed to fire, it expands to form a heat insulation barrier.

[0031] Please refer to Figure 2 and Figure 4 The window sash 2 has a locking handle 3 on its front side wall. The locking handle 3 can be rotated to drive the internal lock cylinder to be fixedly connected to the side wall of the window frame body 1. At the same time, the front of the window sash 2 has a placement groove 4, which is adapted to the inner wall of the window frame body 1. Limiting baffles 5 are fixedly installed at both the upper and lower ends of the inner wall of the placement groove 4. The sides of the limiting baffles 5 are inclined, and the inclined ends of the limiting baffles 5 are provided with teeth. Then, a sealing component 10 is filled inside the placement groove 4. The sealing component 10 includes a fixed silicone strip, a graphite-based expansion sealing strip, and an airtight pressure strip. The graphite-based expansion sealing strip expands more than 3 times its volume after being heated, which can fill the gap between the window sash 2 and the window frame body 1 to prevent toxic gases and flames from leaking to the outside.

[0032] Working principle: When using this utility model, tempered glass is placed inside the glass mounting groove 8, and then the fixing baffle 9 is placed on the outside of the glass, so that the fixing baffle 9 presses the glass while being located inside the glass mounting groove 8. Then, it is fixed and installed by bolts. Then, the fixing silicone strip, graphite-based expansion sealing strip and airtight pressure strip are pressed into the groove 4 in sequence. The limiting baffle 5 can complete the limiting and fixing. Then, the window sash 2 is closed, and then the locking handle 3 is turned to complete the closure between the window frame body 1 and the window sash 2.
