Description

Technical Field

[0001] This utility model relates to the field of firewall technology, specifically to a firewall with good sound insulation performance. Background Technology

[0002] Firewalls are made of non-combustible materials with a fire resistance rating of not less than 3 hours. They are vertical partitions or fire-resistant walls installed directly on the foundation of buildings or reinforced concrete frames to reduce or avoid heat radiation hazards to buildings, structures, and equipment and to prevent the spread of fire.

[0003] Currently, firewalls have many inherent defects. For example, traditional firewalls are mostly made of a single fireproof material (such as concrete or aerated concrete blocks), which is insufficient in sound insulation performance, especially in blocking low-frequency noise (such as traffic and equipment vibration), and cannot meet the needs of prefabricated construction sites. At the same time, firewalls require brickwork during construction and installation, but the bricks are small, which makes the construction efficiency low. In addition, gaps may be formed between the bricks, causing air circulation and affecting the fire resistance of the wall. Utility Model Content

[0004] This invention addresses the shortcomings of existing technologies by providing a firewall with excellent sound insulation performance, thereby solving the problems of poor sound insulation performance and low assembly efficiency of traditional firewalls mentioned in the background section.

[0005] To achieve the above technical objectives, this utility model proposes the following technical solution: a firewall with good sound insulation performance, comprising a firewall body, with multiple columns spliced ​​together to form a frame on both sides of the firewall body, and a top keel and a bottom keel respectively at the top and bottom ends of the firewall body, the firewall body including several sound-insulating and fireproof boards, the sound-insulating and fireproof boards including a cenosphere fire-resistant insulation board and a cenosphere high-resistance board located outside the cenosphere fire-resistant insulation board, a sound-insulating damping layer between the cenosphere fire-resistant insulation board and the cenosphere high-resistance board, several horizontal frames evenly provided between the top keel and the bottom keel, and several vertical frames provided between two of the aforementioned columns.

[0006] Furthermore, the soundproof and fireproof board has slots on both sides, and the column and the vertical frame have locking blocks that match the slots on one side and both sides of the vertical frame. The horizontal frame has sliding grooves on both the upper and lower sides.

[0007] Furthermore, the interior of each card block is filled with fireproof rock wool that has sound insulation properties.

[0008] Furthermore, the firewall body has a pre-embedded conduit, and the inside of the conduit is filled with fireproof rock wool.

[0009] Furthermore, the outer wall of the high-durability beaded plate is provided with micro-perforations arranged in an array, the diameter of the micro-perforations is 0.6-1mm, and the perforation rate is 6%-11%.

[0010] Compared with the prior art, the beneficial effects of this utility model are as follows: This utility model uses a core board of cenosphere fire-resistant insulation board and a face board of cenosphere high-resistance board, and adds a sound insulation damping layer between the cenosphere fire-resistant insulation board and the cenosphere high-resistance board to form a composite system of fireproofing and sound insulation; at the same time, the sound insulation effect can be further improved by pre-embedding conduits and filling the conduits with fireproof rock wool, and by opening micro-perforations on the outer surface of the cenosphere high-resistance board; through the combined use of columns, horizontal frames and vertical frames, it can be easily assembled, and the installation efficiency can be significantly improved compared with the traditional installation method.

[0013] The following are specific embodiments of the present invention, and the technical solution of the present invention will be further described in conjunction with the accompanying drawings. However, the present invention is not limited to these embodiments.

[0014] like Figure 1-4 As shown, this utility model provides a firewall with good sound insulation performance, including a firewall body 1. Both sides of the firewall body 1 are provided with a frame formed by splicing multiple columns 2. The upper and lower ends of the firewall body 1 are respectively provided with a top keel 3 and a bottom keel 4. The firewall body 1 includes a number of sound-insulating and fireproof boards 5. The sound-insulating and fireproof boards 5 include a cenosphere fire-resistant heat-insulating board 51 and a cenosphere high-resistance board 52 located outside the cenosphere fire-resistant heat-insulating board 51. A sound-insulating damping layer 53 is provided between the cenosphere fire-resistant heat-insulating board 51 and the cenosphere high-resistance board 52. A number of horizontal frames 6 are evenly provided between the bottom keel 4 and the top keel 3. A number of vertical frames 7 are provided between the two columns 2.

[0015] like Figure 1 and Figure 2As shown in the figure, in this embodiment, a cenosphere fire-resistant insulation board 51 (density ≤0.9g / cm³) is used as the core board, and a cenosphere high-resistance board 52 is used as the face board, forming a composite structure of lightweight core material and rigid surface layer. This achieves the design concept of reducing the self-weight of the wall by more than 70% while maintaining a fire resistance limit of ≥5 hours (meeting GB 60017 standard). At the same time, a sound insulation damping layer 53 is added between the cenosphere fire-resistant insulation board 51 and the cenosphere high-resistance board 52, thereby increasing the sound insulation performance and forming a composite system of fireproofing and sound insulation. The sound insulation damping layer is preferably a rock wool board with good fireproofing and sound absorption and noise reduction effects. The rock wool board contains a large number of fine long fibers, which form a porous connection structure, which can significantly improve the sound insulation effect. In this embodiment, the sound insulation and fireproof board 5 is installed step by step from bottom to top. First, the ground joists 4 and the top joists 3 are fixed to the ground and the top, respectively. Then, a column 2 is installed at one end of the ground joist 4. Finally, the prefabricated standard ruler The soundproof and fireproof board 5 is assembled along the ground joists 4, and then multiple sets of vertical frames 7 and soundproof and fireproof boards 5 are installed in sequence. After the vertical frames 7 and soundproof and fireproof boards 5 on the first layer are installed, the columns 2 on the other side of the firewall body 1 are installed. Then, the horizontal frames 6 are installed on the top of this layer, and then the columns 2, multiple sets of soundproof and fireproof boards 5 and vertical frames 7 are installed on the horizontal frames 6. Finally, the columns 2 are installed, and so on for the installation of the third layer, the fourth layer, etc. After installation, flexible sealant is used to fill the joints of the boards to reduce sound leakage through the gaps. Compared with the existing technology, it can significantly improve the installation efficiency. At the same time, the standardized design and production, and the relatively uniform size and weight provide convenience for transportation.

[0016] The soundproof and fireproof board 5 has slots 8 on both sides, and the column 2 and the vertical frame 7 have blocks 9 that are compatible with the slots 8 on one side and both sides. The vertical frame 7 or the column 2 and the soundproof and fireproof board 5 are connected side by side through the blocks 9 and slots 8. The horizontal frame 6 has sliding grooves 10 on both the upper and lower sides.

[0017] like Figure 3 As shown, during assembly, the combination of slot 8 and block 9 can improve the splicing effect of soundproof and fireproof board 5 with column 2 and vertical frame 7.

[0018] The card block 9 is filled with fireproof rock wool that has sound insulation properties.

[0019] like Figure 2 As shown, the fireproof rock wool filling inside the card block 9 can effectively prevent sound from propagating from the card block 9, further improving the sound insulation effect.

[0020] A conduit 11 is pre-embedded on the main body 1 of the firewall, and the inside of the conduit 11 is filled with fireproof rock wool.

[0021] like Figure 3As shown, a conduit 11 for supporting water and electricity pipelines to flexibly pass through is pre-embedded at a certain position in the main body 1 of the firewall, and fireproof rock wool is filled inside the conduit 11 to avoid the loss of sound insulation performance caused by later opening, and further improve the sound insulation effect.

[0022] The outer surface of the high-durability beaded board 52 is provided with micro-perforations arranged in an array. The diameter of the micro-perforations is 0.6-1mm and the perforation rate is 6%-11%.

[0023] like Figure 1 As shown, by creating micro-perforations with a diameter of 0.6-1mm on the outer surface of the high-density beaded board 52, and combining it with rock wool board to form a Helmholtz resonance sound-absorbing structure, it can specifically absorb noise in the 260-2000Hz frequency band, further improving the sound insulation effect. The perforation rate is controlled at 6%-11% to avoid the structural strength decreasing if it is too high, and the sound absorption effect being insignificant if it is too low.

[0024] Operating principle: During assembly, first fix the ground joists 4 and top joists 3 to the ground and ceiling respectively with bolts. Then, install a column 2 at one end of the ground joist 4. Next, assemble the prefabricated standard-sized soundproof and fireproof boards 5 along the ground joists 4. Then, install multiple sets of vertical frames 7 and soundproof and fireproof boards 5 in sequence. After the vertical frames 7 and soundproof and fireproof boards 5 on the first layer are installed, install the column 2 on the other side of the firewall body 1. Then, install the horizontal frame 6 at the top of this layer with self-tapping screws. Then, install the column 2, multiple sets of soundproof and fireproof boards 5, and vertical frames 7 on the horizontal frame 6. Finally, install the column 2 on the other side, and so on for the third, fourth, and so on. After installation, fill the joints of the boards with flexible sealant. The specific embodiments described herein are merely illustrative examples illustrating the spirit of this utility model. Those skilled in the art to which this utility model pertains may make various modifications or additions to the described specific embodiments or use similar methods to replace them, without departing from the spirit of this utility model or exceeding the scope defined by the appended claims.
