Description

Technical Field

[0001] The utility model belongs to the technical field of assembled wall bodies, and in particular relates to a sound insulation quick-install plate. Background Art

[0002] As the level of urbanization increases, environmental noise issues arise. To protect privacy and to ensure that work and life are not disturbed, commercial or residential buildings have increasingly higher requirements for room sound insulation.

[0003] However, the current sound insulation structure of partition walls mostly adopts a light steel keel wall structure, with rock wool inside and two layers of wall panels on the outside, which has poor sound insulation effect. Generally speaking, it is necessary to increase the wall density and thickness as much as possible to improve the wall sound insulation. However, blindly increasing the number of layers and the overall thickness of the wall not only causes a waste of materials and space, but also fails to effectively reduce the weakening of the overall sound insulation effect of the wall due to resonant sound transmission and sound bridges. Moreover, the keel that runs through the structure has the problem of sound bridges, which is a weak point in the wall sound insulation, lowering the overall sound insulation and further reducing the sound insulation effect of the wall. In addition, multiple workers are required for on-site installation, which consumes manpower. Utility Model Content

[0033] In order to better explain the present invention and facilitate understanding, the present invention is described in detail below through specific implementation modes in conjunction with the accompanying drawings.

[0034] like Figure 1-5 As shown, the utility model provides a sound insulation quick-install plate, comprising a top keel 1, a ground keel 2 and a plate body 3 fixed between the top keel 1 and the ground keel 2.

[0035] like Figure 1 , Figure 2 As shown, the plate body 3 is a centrosymmetrical structure, the central layer is a central sound insulation layer 31, and the central sound insulation layer 31 is sequentially provided with a sound absorbing layer 32, a secondary sound insulation layer 33, a damping layer 34 and a primary sound insulation layer 35 on both sides thereof.

[0036] The density of the central sound insulation layer 31 and the primary sound insulation layer 35 is greater than the density of the secondary sound insulation layer 33. In this embodiment, the central sound insulation layer 31 and the primary sound insulation layer 35 are cement fiber boards or glass magnesium boards. The secondary sound insulation layer 33 is a sound insulation gypsum board. The material of the sound absorption layer 32 is a fiber porous material or a foamed porous material such as rock wool, glass fiber felt, ceramic fiber felt and a composite material thereof. The material of the damping layer 34 is rubber or PVC.

[0037] It can be seen that the plate 3 is a symmetrical arrangement of multiple layers of materials, so that the sound absorption and sound insulation work together and interact with each other. Due to the different densities between the materials, multiple reflection interfaces are increased. This method of using multiple acoustic materials in combination greatly increases the sound insulation performance of the plate 3, so that the plate 3 can also achieve high sound insulation performance at a relatively thin thickness. In addition, the added damping layer 34 prevents the structure from generating low-frequency resonance.

[0038] The thickness of the plate 3 ranges from 100mm to 120mm. The test is carried out according to the American standard with a test area of ​​10m2. The test results show that the sound insulation range of the plate 3 can reach 50-55dB. Compared with the wall of the same thickness, it has high sound insulation performance.

[0039] When processing the plate body 3, it needs to be prefabricated in the factory and then directly spliced ​​into a wall on site, which saves installation manpower and only requires two to three workers to install.

[0040] like Figure 2 As shown, the sound absorbing layers 32 on the left and right sides of the plate body 3 are recessed in the adjacent central sound insulation layer 31 and the secondary sound insulation layer 33 to form two installation grooves 36, and U-shaped keels 5 penetrating through the upper and lower ends of the plate body 3 are embedded in the two installation grooves 36 to seal the edge of the plate body 3 and also support the plate body 3.

[0041] Two adjacent plates 3 need to be spliced ​​together by a connecting member 6. Specifically, the respective mounting grooves 36 are combined into a connecting groove, and the connecting member 6 and the connecting groove are adapted to be arranged in the connecting groove. Figure 3As shown, the connector 6 is a composite material, including a first layer 61, a second layer 62, a third layer 63 and a fourth layer 64 which are coaxially sleeved from the inside to the outside. The first layer 61 is a porous material layer, the second layer 62 is a steel pipe, the third layer 63 is an inorganic material layer, and the fourth layer 64 is a sound insulation felt layer. The steel pipe of the second layer 62 is used as a support, and the inorganic material layer of the third layer 63 is the outer wrapping of the steel pipe of the second layer 62. After the two are combined, the connector 6 has both support and can prevent metal from being exposed to the outside to form a sound bridge. Therefore, the structure combining metal and inorganic materials not only ensures the support performance of the connector 6, but also enhances the overall rigidity of the structure at the connection between the two adjacent plates 3, and reduces its sound transmission and heat conductivity, which has a good effect on the sound insulation performance and thermal insulation performance. Among them, the material of the inorganic material layer is gypsum, cement or magnesium-based material.

[0042] When making the connector 6, first pour the inorganic material in the third layer 63 into the mold, put the steel pipe of the second layer 62 into it before it sets, and then pour the inorganic material in the third layer 63 on top for a second time, so that the steel pipe of the second layer 62 is wrapped by the inorganic material, and then take it out after drying, and stick it around with the sound insulation felt layer with adhesive backing, that is, the fourth layer 64. Among them, the porous material of the first layer 61, such as rock wool, is stuffed into the steel pipe of the second layer 62 to divide the large space into small spaces to allow sound waves to reflect multiple times.

[0043] like Figure 1 , Figure 4-5 As shown, both the top keel 1 and the ground keel 2 are L-shaped keels 4 with two openings arranged opposite to each other, a first gap 11 is left between the horizontal walls 41 of the two L-shaped keels 4 of the top keel 1 and is fixed to the upper edge of the wall hole, and a first groove 12 is formed between the vertical walls 42 of the two L-shaped keels 4 of the top keel 1, and the notch of the first groove 12 is downward.

[0044] A second gap 21 is left between the horizontal walls 41 of the two L-shaped keels 4 of the floor keel 2 and is fixed to the lower edge of the wall hole. A second groove 22 is formed between the vertical walls 42 of the two L-shaped keels 4 of the floor keel 2, and the notch of the second groove 22 faces upward.

[0045] The first gap 11 and the second gap 21 are used to cut off the sound bridge and block the propagation of sound, and the rubber 13 filled in the first gap 11 and the second gap 21 can further improve the effect of blocking the propagation of sound. In addition, the outer side of the L-shaped keel 4 is wrapped with a sound insulation felt 43 to improve the sound insulation effect.

[0046] The upper and lower ends of the plate body 3 are respectively embedded in the first groove 12 and the second groove 22 .

[0047] When installing the plate body 3 , first install the ceiling keel 1 , then install one L-shaped keel 4 in the floor keel 2 , then fill the second gap 21 with rubber 13 and put the plate body 3 in, and finally install the other L-shaped keel 4 in the floor keel 2 .

[0048] Moreover, since the raw materials used in the plate body 3 except for the damping layer and the steel components are all inorganic materials, it also has certain development potential in building fire protection, and also has the performance of thermal insulation.
