Description

Technical Field

[0001] This utility model relates to the field of sound insulation devices, specifically to a sound insulation device for fireproof boards. Background Technology

[0002] The main function of fire-resistant boards is to provide fire resistance, slow the spread of fire, reduce heat transfer efficiency, and decrease the release of smoke and harmful gases. Specifically, fire-resistant boards can form an effective barrier during a fire, preventing flames from rapidly spreading to other parts of the building, thus buying more time for evacuation and fire rescue. For example, patent application number 01202479.1 discloses a fire-resistant board that includes at least a substrate made of foamed phenolic resin. It has the following advantages: this fire-resistant board is lightweight and has excellent fire resistance; the foaming process saturates the phenolic resin, eliminating its water absorption properties and providing both waterproofing and aesthetic appeal.

[0003] However, the patent still has the following drawbacks: due to the relatively simple structure of the fireproof board, its function is relatively limited. Utility Model Content

[0004] In view of the above-mentioned defects or deficiencies in the prior art, it is desirable to provide a sound insulation device for fireproof boards, so that the fireproof boards have good sound insulation effect and can also improve the firmness of the boards after splicing.

[0005] According to the technical solution provided by this utility model embodiment, a sound insulation device for fireproof boards includes a frame, and a sound insulation board is fixedly installed inside the frame; the thickness of the frame is equal to the thickness of the sound insulation board, and the surface of the sound insulation board is provided with sound-absorbing holes. The frame consists of two parts, auxiliary plates, which are installed on the sides of the frame using countersunk screws; the sides of the auxiliary plates are provided with countersunk holes corresponding to the countersunk screws, and the sides of the frame are provided with threaded grooves matching the countersunk screws. There are four auxiliary plates, splicing blocks, which are respectively fixedly installed on the sides of the left and rear auxiliary plates. The sides of the right and front auxiliary plates are provided with slots, splicing grooves, and through grooves, and threaded sleeves are fixedly installed in the through grooves. The connecting block matches the splicing groove. The through grooves are located above and below the splicing groove, and the slots are located above and below the through groove. A bolt is attached, with its end passing through the additional block and screwed into the inside of the threaded sleeve. The surface of the additional block has a through hole corresponding to the bolt, and the additional block is located within the slot. An insert is fixedly connected to the additional block. The end of the insert passes through the auxiliary plate, and the side of the auxiliary plate has an opening corresponding to the insert. A spring connects the threaded sleeve and the movable plate. The movable plate is slidably installed within the through groove, and the end of the bolt abuts against the side of the movable plate. A post is fixedly connected to the movable plate, and the side of the splicing block has a slot matching the post.

[0006] In summary, the beneficial effects of this utility model are as follows:

[0007] 1. The fireproof board has a good sound insulation effect through the setting of frame, sound insulation board, auxiliary board and countersunk screw;

[0008] 2. By using splicing blocks, slots, splicing grooves, through grooves, threaded sleeves, bolts, additional blocks, inserts, springs, movable plates, and inserts, the strength of the spliced ​​panels can be improved. Attached Figure Description

[0017] Please refer to Figure 1 , Figure 2 , Figure 3 and Figure 4 A sound insulation device for fireproof boards includes a frame 1, with a sound insulation board 2 fixedly installed inside the frame 1; an auxiliary plate 3, which is installed on the side of the frame 1 by countersunk screws 4; splicing blocks 5, which are fixedly installed on the sides of the left and rear auxiliary plates 3 respectively, and the sides of the right and front auxiliary plates 3 are provided with slots 6, splicing slots 7 and through slots 8, with threaded sleeves 9 fixedly installed in the through slots 8; bolts 10, the end of which passes through an additional block 11 and is screwed into the threaded sleeve 9; insert blocks 12, which are fixedly connected to the additional block 11; springs 13, which are connected between the threaded sleeves 9 and a movable plate 14; and insert posts 15, which are fixedly connected to the movable plate 14.

[0018] like Figure 1 , Figure 2 and Figure 3 As shown, the thickness of the frame 1 is equal to the thickness of the sound insulation board 2, and the surface of the sound insulation board 2 is provided with sound-absorbing holes. The side of the auxiliary plate 3 is provided with countersunk holes corresponding to the countersunk screws 4, and the side of the frame 1 is provided with threaded grooves that match the countersunk screws 4, which facilitates the installation of the countersunk screws 4.

[0019] like Figure 1 , Figure 2 , Figure 3 and Figure 4 As shown, there are four auxiliary plates 3, two frame pieces 1, and the splicing blocks 5 match the splicing grooves 7. The through grooves 8 are located above and below the splicing grooves 7, and the slots 6 are located above and below the through grooves 8.

[0020] like Figure 1 , Figure 2 , Figure 3 and Figure 4 As shown, the surface of the additional block 11 has through holes corresponding to the bolt 10, facilitating the installation of the bolt 10. The additional block 11 is located within the slot 6. The end of the insert block 12 passes through the auxiliary plate 3, and the side of the auxiliary plate 3 has an opening corresponding to the insert block 12, facilitating the passage of the insert block 12.

[0021] In use: First, make a groove matching the insert 12 on the side of the fireproof surface of the fireproof board. Then remove the bolt 10. The spring 13 will gradually return from the stretched state, which can drive the insert 15 into the through groove 8. Then, use fireproof adhesive to bond the fireproof surface to the upper and lower frame 1 respectively. Then, bond the substrate between the upper and lower frame 1, so that the fireproof board has a good sound insulation effect. When splicing multiple boards, the splicing block 5 of one board can be inserted into the splicing groove 7 of another board. Then, insert the insert 12 through the opening and insert it into the groove of the fireproof surface, so that the fireproof surface is less likely to fall off during use. Then, thread the end of the bolt 10 through the additional block 11 and screw it into the inside of the screw sleeve 9, and make the end of the bolt 10 abut against the side of the movable plate 14. The insert 15 will be inserted into the slot of the splicing block 5, which can improve the firmness of the spliced ​​boards.
