[0025] As Figures 1 to 3 shown, a sound-insulating and fire-proof door leaf structure described in the present utility model includes a door leaf frame 1 and a sound-insulating and fire-proof board body 2. A positioning ring groove 11 is formed on the inner wall of the door leaf frame 1. The sound-insulating and fire-proof board body 2 includes a sound-insulating outer layer 21, a fire-proof intermediate layer 22, and a sound-insulating inner layer 23 which are sequentially stacked together. The sound-insulating and fire-proof board body 2 is arranged inside the door leaf frame 1, and the four peripheral sides of the sound-insulating and fire-proof board body 2 are embedded in the positioning ring groove 11.

[0026] In this sound-insulating and fire-proof door leaf structure, the sound-insulating and fire-proof board body 2 is adopted, and the sound-insulating and fire-proof board body 2 includes a sound-insulating outer layer 21, a fire-proof intermediate layer 22, and a sound-insulating inner layer 23 which are sequentially stacked together. This can not only meet the requirements of sound insulation in both directions inside and outside, but also achieve the requirement of fire prevention. Therefore, this sound-insulating and fire-proof door leaf structure can achieve an excellent sound insulation effect, thereby greatly improving the mute performance and safety in use. It has various functions and can meet higher usage requirements.

[0027] By opening a positioning ring groove 11 on the inner wall of the door leaf frame 1 and fitting the peripheral side edges of the sound insulation and fireproof board body 2 into the positioning ring groove 11. This can utilize the positioning ring groove 11 to position the periphery of the sound insulation and fireproof board body 2, which can not only play a very stable and reliable positioning role for the sound insulation and fireproof board body 2, but also enable the sound insulation and fireproof board body 2 to exhibit more stable and reliable sound insulation and fireproof performance, thereby enabling the sound insulation and fireproof door leaf structure to have very high reliability and applicability.

[0028] In the actual manufacturing process, the sound insulation outer layer 21, the fireproof intermediate layer 22 and the sound insulation inner layer 23 can be respectively composed of independent plates; or a plate can be used to form the fireproof intermediate layer 22, and sound insulation materials can be respectively pasted on the inner and outer surfaces of the fireproof intermediate layer 22 to form the sound insulation inner layer 23 and the sound insulation outer layer 21; these can all meet the requirements of actual manufacturing and use.

[0029] The fireproof intermediate layer 22 is a fireproof calcium silicate board or a fireproof glass fiber board or a fireproof magnesium oxychloride board. Such a fireproof intermediate layer 22 can not only have very strong fireproof performance, but also play a heat preservation role, thereby helping to further improve the fireproof performance and heat preservation performance of the sound insulation and fireproof door leaf structure, and further helping to improve the reliability and applicability of the sound insulation and fireproof door leaf structure.

[0030] As Figure 3 shown, the thickness T0 of the fireproof intermediate layer 22 is above 4 mm. This can not only enable the fireproof intermediate layer 22 to have high structural strength, but also enable the fireproof intermediate layer 22 to have good fireproof performance, thereby being conducive to further improving the reliability and applicability of the sound insulation and fireproof door leaf structure.

[0031] As Figure 3 shown, the thickness T0 of the fireproof intermediate layer 22 is 4 mm, 5 mm, 10 mm, 15 mm, 20 mm or 24 mm. This can not only enable the fireproof intermediate layer 22 to have a stable and reliable structure, but also be convenient for manufacturing, and be conducive to enabling the fireproof intermediate layer 22 to have very good fireproof performance.

[0032] Both the sound insulation outer layer 21 and the sound insulation inner layer 23 are elastic sound insulation layers, and the sound insulation outer layer 21 and the sound insulation inner layer 23 are respectively elastically pressed against the opposite groove walls of the positioning ring groove 11. By adopting elastic sound insulation layers and elastic pressing installation, the purpose of flexible contact can be achieved, thereby reducing the transmission of sound. This can not only improve the stability and reliability of the installation and positioning of the sound insulation and fireproof board body 2, but also enable the sound insulation and fireproof board body 2 to exhibit more stable and reliable sound insulation performance, and further help to improve the reliability and applicability of the sound insulation and fireproof door leaf structure.

[0033] Both the sound insulation outer layer 21 and the sound insulation inner layer 23 are damping sound insulation felts. This enables the sound insulation outer layer 21 and the sound insulation inner layer 23 to have very strong sound insulation performance, thereby facilitating the further improvement of the sound insulation performance of the sound insulation and fireproof door leaf structure.

[0034] In the actual manufacturing process, the sound insulation outer layer 21 and the sound insulation inner layer 23 can be adhesively fixed on the inner and outer surfaces of the fireproof intermediate layer 22 through glue, so as to meet the manufacturing and use requirements of the sound insulation and fireproof board body 2.

[0035] As Figure 3 shown, the thickness T1 of the sound insulation outer layer 21 is 1.2 - 3 mm, and the thickness T2 of the sound insulation inner layer 23 is 1.2 - 3 mm. This not only helps to control the manufacturing costs of the sound insulation outer layer 21 and the sound insulation inner layer 23, but also enables the sound insulation outer layer 21 and the sound insulation inner layer 23 to have very good sound insulation performance, which contributes to the further improvement of the applicability of the sound insulation and fireproof door leaf structure.

[0036] As Figure 3 shown, in the actual manufacturing process, the thickness T1 of the sound insulation outer layer 21 can be selected as 1.2 mm, 1.5 mm, 2 mm, 2.5 mm or 3 mm, and the thickness T2 of the sound insulation inner layer 23 can be selected as 1.2 mm, 1.5 mm, 2 mm, 2.5 mm or 3 mm; these can all very well meet the actual use requirements. Among them, when the thickness T1 of the sound insulation outer layer 21 and the thickness T2 of the sound insulation inner layer 23 both adopt 3 mm, the sound insulation and fireproof door leaf structure can achieve extremely strong sound insulation performance, so that the sound insulation performance of the sound insulation and fireproof door leaf structure is extremely high.

[0037] As Figures 4 to 6 shown, a reinforcing rod 3 is arranged inside the door leaf frame 1, and both ends of the reinforcing rod 3 are connected to the inner wall of the door leaf frame 1. The reinforcing rod 3 also divides the inner cavity of the door leaf frame 1 into two installation cavities 10. Mounting grooves 31 are respectively formed on two side walls of the reinforcing rod 3, and the two mounting grooves 31 and the positioning ring grooves 11 on the corresponding side together form an annular positioning groove 20. There are two sound insulation and fireproof board bodies 2, and the two sound insulation and fireproof board bodies 2 are respectively arranged in the two installation cavities 10, and the peripheral side edges of the two sound insulation and fireproof board bodies 2 are respectively embedded in the corresponding annular positioning grooves 20. In this way, when manufacturing large-sized door leaves, not only can the sound insulation and fireproof door leaf structure have high structural strength, but also the sound insulation and fireproof door leaf structure can have very high sound insulation and fireproof performance, thereby facilitating the manufacture of very reliable and applicable door leaves.

[0038] As Figures 4 to 6As shown, the reinforcing bar 3 is vertically arranged at the middle position of the inner cavity of the door leaf frame 1. Two clamping grooves 31 are respectively opened on the left and right side walls of the reinforcing bar 3. The left and right clamping grooves 31 and the left and right ends of the positioning ring groove 11 together form an annular positioning groove 20. This can help the reinforcing bar 3 play a more stable and reliable reinforcing role, thereby facilitating the manufacture of a more stable and reliable large-sized door leaf. And this can also facilitate the unified manufacture of the sound insulation and fireproof board, thus helping to improve the convenience of manufacture.

[0039] As Figure 2 , Figure 7 and Figure 8 shown, the door leaf frame 1 includes two horizontal side frames 12 and two vertical side frames 13. The two horizontal side frames 12 are arranged side by side up and down. The left and right ends of the upper horizontal side frame 12 are respectively connected to the upper ends of the two vertical side frames 13, and the left and right ends of the lower horizontal side frame 12 are respectively connected to the lower ends of the two vertical side frames 13. Positioning card slots 30 are respectively opened on the inner walls of the two horizontal side frames 12 and the two vertical side frames 13. The positioning card slots 30 are connected end to end in a ring to form a positioning ring groove 11. Such a door leaf frame 1 is very simple and reliable. This can not only facilitate the manufacture of the door leaf frame 1, but also help assemble a reliable positioning ring groove 11, thus facilitating manufacture.

[0040] In the actual manufacturing process, the sound insulation and fireproof board body 2 is assembled together when assembling the door leaf frame 1. Specifically: after the two vertical side frames 13 and one of the horizontal side frames 12 are assembled, three sides of the sound insulation and fireproof board body 2 are inserted into the positioning card slots 30 of this horizontal side frame 12 and the two vertical side frames 13; finally, the other horizontal side frame 12 is installed, and the positioning card slot 30 on this horizontal side frame 12 is clamped on the remaining side of the sound insulation and fireproof board body 2. In this way, the assembly requirements can be met, and thus the requirements of actual manufacturing and use can be satisfied. When the reinforcing bar 3 is provided, first assemble the two vertical side frames 13, one of the horizontal side frames 12 and the reinforcing bar 3 together; then insert the two sound insulation and fireproof board bodies 2; finally install the other horizontal side frame 12; this can complete the assembly requirements of the large-sized door leaf. The setting of the reinforcing bar 3 is not limited to being used on large-sized door leaves. The reinforcing bar 3 can also be installed on small-sized door leaves to achieve the reinforcing effect.

[0041] As Figure 2 , Figure 5 , Figures 7 to 9 shown, in the actual use process, this sound insulation and fireproof door leaf structure can be used as a hanging board door leaf. Decorative panels 100 are respectively hung on the front and rear walls of this sound insulation and fireproof door leaf structure through hanging components 40. In order to satisfy the hiding of the hanging components 40 and facilitate the decorative panel 100 to be directly attached to the sound insulation and fireproof door leaf structure, accommodating grooves 50 can be respectively opened on the front and rear walls of the sound insulation and fireproof door leaf structure for the hanging components 40 to be accommodated. This can help assemble a very stable and reliable door leaf.

[0042] The above embodiments are the preferred embodiments of the present utility model. Any structure similar to the present utility model and equivalent changes made thereto shall fall within the protection scope of the present utility model.
