Description

Technical Field

[0001] The utility model relates to a high sound insulation wall. Background Art

[0002] In order to improve the sound insulation performance of the wall, in conventional technology, in addition to significantly increasing the wall thickness, a layer is usually added to the surface of the basic wall, so that the sound conduction process increases through multiple different material layers and overhead layers. For light steel keel walls, the typical practice is to use double rows of keels to reduce their sound bridge effect. The first problem with these practices is that in order to achieve an improvement in sound insulation performance, the wall thickness must be increased; and the construction period is extended and the cost is correspondingly increased.

[0003] In recent years, there have been methods such as adding sandwich panels between double-row keels or using non-metallic connectors between double-row keels, forming the concept of "broken bridge keels". Such methods can effectively improve the sound insulation performance of the wall and improve the convenience of construction. However, on the one hand, the wall thickness cannot be too thin, and the necessary supplementary contents such as panel openings required for wiring in the wall and reinforced structures at the openings of doors and windows either require double-cavity structures, resulting in increased costs, or damage to the sound insulation performance, which limits the sound insulation effect of the wall, including pipelines, niches, and embedded equipment (such as distribution boxes or manifolds). Utility Model Content

[0009] The high sound insulation wall also includes an L-shaped top and bottom keel and an L-shaped closing keel.

The wall panel is against the horizontal bottom plate of the top and bottom keel, and the inner wall surface of the wall panel is attached to the outside of the vertical plate of the top and bottom keel.

[0010] The wall panel is a double-layer board, including a first layer board and a second layer board.

[0011] The wire threading tube is installed on the pipeline box. The wire threading holes on the pipeline box are misaligned with the wire threading holes on the embedded box. The wires are bent and inserted into the embedded box, and glue is applied to the wire threading tube and the rubber rings on the wire threading holes of the embedded box.

[0040] The following examples are merely used to illustrate possible implementations of the present invention, but are not intended to limit the scope of protection of the present invention, so it is necessary to make it clear in advance.

[0041] like Figures 1 to 5CAs shown, it is a preferred embodiment of a high sound insulation wall of the utility model, which includes a broken bridge keel 1, a through-core keel 2, a wall panel 3, an L-shaped top and bottom keel 4 and an L-shaped closing keel. The broken bridge keel 1 includes a profile base plate 11 and two metal side plates 12. The metal side plates 12 include a bottom plate, one end of which is L-shaped to form an inner folding edge 121, and the other side of the bottom plate is hook-shaped. The profile base plate 11 is made of metal and is covered with soft film layers 13 on both sides. The profile base plate is U-shaped, and the free ends of its two side plates are in an inner curling shape. The hooks of the metal side plates are engaged with the soft film layer. The broken bridge keel uses the resonance points of different materials to distinguish and destroy or weaken the sound bridge effect of the keel, so that the light steel keel / paper film gypsum board wall can improve the sound insulation effect of the wall under the premise of the conventional single-row keel assembly method. At the same time, the necessary thickness of the wall is reduced and the installation is simple. The outer walls of the two side panels of the thermal keel 1 are affixed with soft films 14 to further improve the sound insulation performance. The soft film sides of the thermal keel are respectively affixed with wall panels 3. The wall panels 3 are double-layer panels, including a first layer panel 31 and a second layer panel 32. The first layer panel is affixed with a shock-absorbing material layer 311. The shock-absorbing material layer is sandwiched between the first layer panel and the second layer panel to further increase the sound insulation effect of the wall. The shock-absorbing material is rubber, synthetic rubber, polyurethane or cork sheet, etc.

[0042] The bottom plate of the thermal keel 1 is provided with a through hole for installing the through keel 2 or routing the wires, and a non-metallic clip 6 is installed between the inner folding edges 121 of the two side plates of the thermal keel 1. Figure 3A and Figure 3B The non-metal clip 6 is integrally formed, including an inverted concave plate 61 and two ear plates 62 arranged on both sides of the inverted concave plate. The groove cover of the inverted concave plate is pressed on the through-core keel 2. The two ear plates are provided with slots 621. The inner folding edge 121 of the broken bridge keel is inserted into the slot. The non-metal clip of this structure requires the accuracy of the broken bridge keel itself to be sufficient. The clip needs to use non-metallic materials (plastic materials), and the resonance points of different materials are used to further destroy or weaken the sound bridge function of the keel; the non-metal clip 6 is placed on the through-core keel 2.

[0043] like FIG. 5A to FIG. 5DAs shown, a reinforcing profile 7 is installed on the open side of the thermal break keel where the wall load-bearing and door opening edge reinforcement are required. The reinforcing profile 7 includes two aluminum profiles 71 and a thermal insulation thermal break 72. The thermal insulation thermal break 72 is connected between two mirror-image aluminum profiles 71. The aluminum profile 71 includes a frame seat, which is provided with three independent cavities. Slots for inserting the thermal insulation thermal break are respectively provided at the inner ends of the frame seat, and a groove 711 for accommodating the inner folding piece of the thermal break keel side panel is provided on the outer side of the frame seat. A V-shaped groove 712 for positioning the screw 40 is bent at the outer end of the side of the frame seat. The reinforcement profile itself needs to be sufficiently rigid, and it also needs to have a groove to accommodate the bent edge of the keel, so it cannot be made into a simple and direct style like a square tube; the three holes in the reinforcement profile are also necessary, and the three holes solve several problems: the existence of the middle hole makes the groove also have a certain structural rigidity; the holes at both ends provide space for external hanging nails, which can ensure that the external wall structure is nailed on both sides of the wall without interfering with each other. For products of different thickness specifications, only the length of the broken bridge needs to be changed. This reinforcement profile not only achieves the reinforcement effect, but also maintains the sound insulation effect of the broken bridge keel.

[0044] High sound insulation wall provides good sound insulation performance, but the pipeline passing through the wall panel will destroy the sound insulation structure, thereby reducing the sound insulation effect. The following solutions can be used for circuit pipelines (such as Figure 4A ), the embedded box is padded with shock-absorbing material and then glued to the middle of the pipeline sleeve 8, the threading tube is installed on the pipeline sleeve 8, the threading hole on the pipeline sleeve is misaligned with the threading hole on the embedded box 9, the wire is bent and inserted into the embedded box, and glue is applied to the threading tube and the rubber ring on the threading hole of the embedded box. When used for water supply pipelines ( Figure 4B ), the connector 20 is padded with shock-absorbing material and bonded to the bottom surface of the pipeline box A30, the water supply pipe is connected to the connector, and the part of the connector extending out of the wall panel is connected to an external eight-shaped valve (not shown). The pipeline box is a five-sided closed box, and adhesive strips are embedded around the open surface to fit the wall panel. It is nailed to the wall panel when in use. The pipeline box not only strengthens the sound insulation structure of the threading part, but also further attenuates the air conduction of sound through the tortuous pipeline path; correspondingly, the cushion layer of shock-absorbing material also attenuates the direct conduction of sound.

[0045] like Figure 2C As shown, another structure of a thermal break keel, the thermal break keel A10 includes a profile substrate A and two metal side panels A, the metal side panels A include a bottom plate A, one end of the bottom plate A is L-shaped to form an inner fold A, and the other side of the bottom plate is hook-shaped, the profile substrate A is made of non-metallic material and is U-shaped, and the free ends of its two side panels are arc-shaped heads A, and the hooks of the metal side panels A are engaged with the arc-shaped head A of the profile substrate A.

[0046] like Figure 3BAs shown, another structure of the non-metal clip is shown. The non-metal clip A5 is integrally formed and includes a vertical plate. Notches are provided on the bottom wall and both side walls of the vertical plate. The lower notches span the through-core keel. A convex plate is provided on one side of the vertical plate at the notches on both sides. The ends of the convex plate and the ends of the vertical plate form a gap. The inner fold of the broken bridge keel is inserted in the gap. The clip spans the through-core keel ( Figure 2 ). It can be used even if the keel bending error is large.

[0047] The assembly method of the high sound insulation wall of the utility model is as follows: after the installation of the thermal insulation keel system is completed and before the wall panel is attached, glue is applied to the gaps between the top and bottom keels, the side keels and the surrounding structures;

[0048] After the first layer of the wall panel is nailed, before the second layer is hung, apply soft colloid at the board seams;

[0049] The second-layer boards are installed offset from the first-layer boards. After the second-layer boards are nailed, kraft paper is glued to the seams between the second-layer boards and the gaps between the second-layer boards and the surrounding structures.

[0050] When the circuit is run inside the wall and needs to be passed out, a pipeline box is applied to the outer layer of the traditional embedded box;

[0051] When the water supply pipe runs inside the wall and needs to be passed out, the water supply pipe is connected to a connector inside the wall, the connector is installed in the sleeve box, and then the connector passes out of the wall panel;

[0052] When the end of the wall is closed, the side of the broken bridge keel close to the surrounding wall is padded with shock-absorbing materials;

[0053] When the wall opening needs to be partially strengthened or the internal load-bearing of the wall needs to be strengthened, reinforcing profiles are used, and the two sides of the thermal break are connected to the thermal break keel and wall panel material respectively.

[0054] The soft colloid is silicone glue, polyurethane or elastic putty.

[0055] Description: Adding double-layer wall panels with soft film on the basis of the broken bridge keel can further increase the sound insulation effect of the wall. In addition to using the broken bridge keel between the wall panels on both sides, any part that may cause a new sound bridge should use a broken bridge structure, such as reinforced profiles, keel clips matching the broken bridge keel, etc. Corresponding to the wall corners and T-shaped joints, shock-absorbing materials should be used for isolation. Where the sound insulation structure is damaged due to the penetration of pipelines, pipeline box-type structures are used to reinforce them. Using multiple techniques such as broken bridge keels, coating on the outside of broken bridge keels, and coating between wall panels, different levels of sound insulation effects can be obtained.

[0056] The traditional high sound insulation wall blocks the sound bridge by means of structural separation. Therefore, while improving the sound insulation effect, it will increase the space occupied, thereby increasing the wall thickness. However, the broken bridge keel described in the utility model has separated the sound bridge itself, so the sound insulation effect is independent of the wall thickness.
