[0025] Next, a soundproof and fireproof door in this exemplary embodiment will be further described.
[0026] In an embodiment of the present application, a plurality of vacuum sound insulation cavities 110 are provided in the titanium alloy composite plate 100, and the plurality of vacuum sound insulation cavities 110 are interconnected and staggered along the length direction of the titanium alloy composite plate 100; by adopting the titanium alloy composite plate 100 as the inner core plate of the door, the excellent high strength, high fire resistance and corrosion resistance of titanium alloy can be utilized to effectively improve the fire resistance and strength of the door; by arranging the vacuum sound insulation cavity 110 therein, the sound insulation effect of the door is improved while improving the above-mentioned performance, and the staggered vacuum sound insulation cavity 110 can ensure that the strength of the titanium alloy composite plate 100 is maintained. A plurality of fireproof reinforcement structures 120 are provided at intervals along the length direction on both sides of the titanium alloy composite plate 100. The fireproof reinforcement structures 120 include a plurality of reinforcement frames 121. The plurality of reinforcement frames 121 are arranged at intervals along the width direction of the titanium alloy composite plate 100. The reinforcement frames 121 are filled with cooling water 122. By providing the reinforcement frames 121 filled with cooling water 122 on both sides of the titanium alloy composite plate 100, the fireproof and heat-insulating performance of the titanium alloy composite plate 100 can be improved.
[0027] The reinforcement plate 200 is provided with a soundproofing groove 210 on the side close to the titanium alloy composite plate 100, and the reinforcement frame 121 is adapted to be inserted into the soundproofing groove 210. By inserting the reinforcement frame 121 into the soundproofing groove 210 of the reinforcement plate 200, the connection strength between the titanium alloy composite plate 100 and the reinforcement plate 200 is enhanced, and the soundproofing groove 210 can improve the sound insulation performance of the connection between the two. The reinforcement plate 200 is provided with a reinforcing rib 220 on the side away from the titanium alloy composite plate 100, and the fireproof door panel 300 is provided with a slot 310 on the side close to the reinforcement plate 200. The reinforcing rib 220 is inserted into the slot 310. By providing the reinforcing rib 220 for insertion into the outer layer of the fireproof door panel 300, the connection strength between the reinforcement plate 200 and the fireproof door panel 300 can be improved.
[0028] Through the above design, the outermost fireproof door panel 300 can provide primary fire protection for the door body, the fireproof reinforcement structure 120 between the reinforcement plate 200 and the fireproof door panel 300 can serve as secondary fire protection and further improve the fireproof and heat-insulating performance, and the titanium alloy composite plate 100 located in the innermost layer can serve as ultimate fire protection and further improve the fireproof performance of the door, the reinforcement plate 200, the reinforcement ribs 220, and the fireproof reinforcement structure 120 can enhance the strength and stability of the door body, and the design of the sound insulation groove 210 and the vacuum sound insulation cavity 110 can improve the sound insulation performance of the door body.
[0029] As an example, an annular sealing strip 230 is embedded on one side of the reinforcing plate 200 close to the titanium alloy composite plate 100, and the cross-section of the annular sealing strip 230 is U-shaped; the cross-section of the vacuum sound insulation cavity 110 is U-shaped, and its main view is a rectangular structure. Receiving grooves 130 are provided on both sides of the titanium alloy composite plate 100 close to the end wall of the vacuum sound insulation cavity 110, and the receiving grooves 130 correspond to the annular sealing strip 230. The annular sealing strip 230 is squeezed and fitted with the end wall of the vacuum sound insulation cavity 110, that is, the U-shaped structure of the annular sealing strip 230 covers the end wall of the vacuum sound insulation cavity 110. On the one hand, it can seal the end wall of the vacuum sound insulation cavity 110, and on the other hand, the rubber elasticity of the sealing strip can also increase the shock resistance of the door body.
[0030] As an example, two adjacent vacuum sound insulation cavities 110 are staggered and disposed adjacent to the two side walls of the titanium alloy composite plate 100. The vacuum sound insulation cavities 110 are staggered and disposed adjacent to the two sides of the titanium alloy composite plate 100 to minimize the reduction in the physical thickness of the titanium alloy composite plate 100 and to minimize the reduction in its strength.
[0031] As an example, the fire protection reinforcement structure 120 is located on a side of the titanium alloy composite plate 100 away from the vacuum sound insulation cavity 110. Specifically, the fire protection reinforcement structure 120 is disposed in correspondence with the vacuum sound insulation cavity 110 to compensate for the reduction in thickness of the titanium alloy composite plate 100 caused by the vacuum sound insulation cavity 110. Furthermore, the insertion of the fire protection reinforcement structure 120 into the reinforcement plate 200 also increases the strength between the titanium alloy composite plate 100 and the reinforcement plate 200.
[0032] As an example, the reinforcing ribs 220 are located on both sides of the vacuum soundproof cavity 110 and the fireproof reinforcement structure 120. Inserting the reinforcing ribs 220 into the slots 310 of the fireproof door panel 300 corresponding to the vacuum soundproof cavity 110 can further improve the strength of the titanium alloy composite panel 100 and the connection strength between the reinforcing panel 200 and the fireproof door panel 300.
[0033] As an example, the inner wall of the sound insulation groove 210 is covered with a sound absorbing cotton layer 211. By providing the sound absorbing cotton layer 211 on the inner wall of the sound insulation groove 210, the sound insulation performance of the fireproof reinforcement structure 120 can be improved.
[0034] As an example, the titanium alloy composite plate 100 is a titanium-zinc composite plate, and the reinforcing plate 200 is a fiber-reinforced cement plate. Titanium-zinc composite plates are highly rigid, inherently possess sound and heat insulation properties, and are easily processed and formed. Fiber-reinforced cement plates offer excellent thermal insulation, high density, excellent sound insulation, and good waterproof and moisture-proof properties, maintaining stable performance. They are lightweight, high-strength, and resistant to deformation. Using plates made of these materials can improve overall strength, fireproofing, and sound insulation, as well as extend service life.
[0035] As an example, a circle of nano fireproof cloth 140 is fixedly connected to the outer side of the titanium zinc composite plate to increase the fireproof performance inside the fire door.
[0036] As an example, the fireproof door panel 300, the reinforcing ribs 220 and the reinforcing frame 121 are all made of metal, have high hardness, and can effectively improve the strength of the door body.
[0037] Although the preferred embodiments of the present invention have been described, those skilled in the art may make additional changes and modifications to these embodiments once they are aware of the basic creative concepts. Therefore, the appended claims are intended to be interpreted as including the preferred embodiments and all changes and modifications that fall within the scope of the present invention.
[0038] Finally, it should be noted that, in this document, relational terms such as first and second, etc., are used only to distinguish one entity or operation from another entity or operation, and do not necessarily require or imply any actual relationship or order between these entities or operations. Moreover, the terms "comprises," "comprising," or any other variations thereof are intended to cover non-exclusive inclusion, such that a process, method, article, or terminal device that includes a series of elements includes not only those elements, but also other elements not explicitly listed, or elements inherent to such process, method, article, or terminal device. In the absence of further limitations, an element defined by the phrase "comprising a ..." does not exclude the presence of additional identical elements in the process, method, article, or terminal device that includes the element.
[0039] The above is a detailed introduction to a soundproof fire door provided by the present invention. Specific examples are used herein to illustrate the principles and implementation methods of the present invention. The description of the above embodiments is only used to help understand the method and core idea of the present invention.
