Description

Technical Field

[0001] This invention relates to the field of door and window technology, and in particular to a high-strength fireproof and bulletproof window structure. Background Technology

[0002] Doors and windows are an important component of building envelope systems and are essential components of all buildings. Some important locations require bulletproof windows due to their special nature. Existing bulletproof windows mostly use thickened bulletproof glass, but the bulletproof performance of the bulletproof window frame used to fix the bulletproof glass and the connection between the bulletproof window frame and the bulletproof glass is neglected. When attacked and impacted, once the bulletproof window frame is damaged, the bulletproof window can easily lose its bulletproof function, or even the entire glass can detach from the bulletproof window frame. Moreover, thickened glass is heavy, expensive, and difficult to replace. Therefore, it is extremely necessary to add bulletproof and anti-detachment functions to the window frame.

[0024] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments.

[0025] Example: This example discloses a high-strength fireproof and bulletproof window structure, such as... Figures 1-7 As shown, it includes: a frame 1, an inner glass layer 9 and an outer glass layer 2 installed inside the frame 1; wherein, the frame 1 includes a bottom plate 102, a top plate 103 and two side plates 101, the side plates 101 being fixedly connected to the bottom plate 102 and the top plate 103; wherein, multiple support members 5 are fixedly connected to the side plates 101 to support the inner glass layer 9 and the outer glass layer 2, thereby enhancing the structural strength of the bulletproof window; and multiple transparent fireproof plates 4 are connected inside the frame 1, the fireproof plates 4 being made of transparent fireproof PVC material, the fireproof plates 4 being connected to the support members 5, the fireproof plates 4 being vertically distributed along the height direction of the frame 1, and the fireproof plates 4 being located between the inner glass layer 9 and the outer glass layer 2, so that when a bullet passes through the outer glass layer 2, the fireproof plates 4 further buffer and block the bullet, thus providing a better bulletproof effect.

[0026] Preferably, the inner wall of the frame 1 is provided with a groove 105 for installing the inner glass layer 9, the width of the groove 105 is the same as the thickness of the inner glass layer 9, and the side of the frame 1 is provided with a slot 106 for installing the outer glass layer 2; a fixing component 3 for fixing the outer glass layer 2 is fixedly connected to the side plate 101, and the outer glass layer 2 is fixedly installed in the slot 106 by the fixing component 3, so as to facilitate the replacement of the outer glass layer 2.

[0027] Preferably, a baffle 7 is fixedly connected to the frame 1 to limit the outer glass 2. The baffle 7 can be glued to the groove 106 to limit the outer side of the outer glass 2 and at the same time provide dustproof and waterproof effect. The baffle 7 is provided with a clearance opening that cooperates with the support plate 6.

[0028] Preferably, a sealing strip 8 is connected between the outer glass 2 and the inner wall of the groove 106. The sealing strip 8 serves to prevent water and dust from entering between the outer glass 2 and the inner glass 9.

[0029] like Figures 4-6 As shown, the fixing component 3 includes a fixing rod 32, which is fixedly connected to the side plate 101 by screws. Multiple fixing members 31 are fixedly connected to the fixing rod 32 for fixing the outer glass layer 2. In this embodiment, three fixing members 31 are provided. The inner wall of the side plate 101 is provided with a sliding groove 108 that slides with the fixing members 31, ensuring the stability of the fixing members 31. The fixing member 31 includes a connecting plate 311, which is fixedly connected to the fixing rod 32 by bolts. An M-shaped elastic clamp is fixedly connected to the connecting plate 311. The elastic clamping component 312 is a thin sheet with a clamping groove 313 that connects with the outer glass 2. When the outer glass 2 is installed in the clamping groove 313, the circumferential surface of the outer glass 2 contacts the inner wall of the groove 106. The elastic clamping component 312 itself has a certain elastic deformation function. By clamping and limiting the outer glass 2 in the clamping groove 313, when the outer glass 2 is hit by a bullet, the elastic clamping component 312 deforms, which plays a buffering and protective role for the outer glass 2 and disperses the impact force received by the outer glass 2.

[0030] Preferably, the fixed rod 32 is provided with multiple sliding holes 33, and a slider 34 is slidably connected in the sliding holes 33. A connecting rod 35 is rotatably connected to the slider 34. The side plate 101 is provided with a first connecting groove 104 that is paired with the connecting rod 35. One end of the connecting rod 35 is rotatably connected in the first connecting groove 104. The connecting rod 35 is connected to the fixed rod 32, which plays a role in supporting and stabilizing the fixed rod 32 and preventing the fixed rod 32 from separating from the side plate 101. When it is necessary to replace the outer glass 2, the screws on the fixed rod 32 are unscrewed and the fixed rod 32 is pulled outward. During the movement, the slider 34 slides in the sliding hole 33, and at the same time, the fixing part 31 slides out from the sliding groove 108, which drives the outer glass 2 out from the groove 106, making it easy to replace the outer glass.

[0031] Preferably, the base plate 102 is provided with a second connecting groove 107, and a support plate 6 is rotatably connected in the second connecting groove 107 for supporting the outer glass 2. In this embodiment, there are two second connecting grooves 107 and two support plates 6, and the support plate 6 is provided with a stop 61, which limits the outer side of the outer glass 2. When the outer glass 2 is replaced, the outer glass 2 is supported by the support plate 6 when it comes out of the groove 106, which prevents the outer glass 2 from falling off. Similarly, during installation, the support plate 6 also supports the outer glass 2, which facilitates the replacement of the outer glass 2.

[0032] like Figure 7 As shown, the support member 5 includes a connecting seat 51, which is fixedly connected to the inner wall of the side plate 101 by bolts. The connecting seat 51 is provided with a connecting block 53, and a pair of sliding plates 55 are slidably connected to the connecting block 53. Support plates 54 are fixedly connected to the ends of the two sliding plates 55 that are far apart from each other, respectively for supporting the inner glass layer 9 and the outer glass layer 2. A buffer spring 56 is fixedly connected between the two sliding plates 55. A baffle 57 fixedly connected to the buffer spring 56 is fixedly connected to the sliding plate 55. The connecting seat 51 is provided with a limiting groove 52 that cooperates with the fireproof plate 4. In this embodiment, the support member 5, by providing two support plates 54 and a buffer spring 56 in the middle, enhances the supporting effect on the outer glass layer 2 and the inner glass layer 9, strengthens the overall structural strength of the bulletproof window, and the buffer spring 56 can buffer the impact force on the outer glass layer 2, further improving the bulletproof effect.

[0033] Finally, it should be noted that in the description of this invention, the terms "vertical," "upper," "lower," "horizontal," etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation.
