Not only that, even in Toutian houses, due to people's requirements for the quality of life and the importance of personal privacy, soundproof and shockproof walls have become an important issue.

At present, in order to make the wall have a better sound insulation effect, it is generally to install additional sound insulation materials on the original wall, such as styrofoam, foam or similar porous materials. However, for the newly completed rough house, if it has to go through cumbersome processes such as wall building and installation of sound insulation panels, it not only wastes manpower, but also takes a lot of time for construction. Therefore, how to quickly and accurately set the soundproof wall has become an urgent problem to be solved.

The embodiments of the present application provide a sound insulation structure, which solves the problem of cumbersome construction process of the current sound insulation wall, which leads to a waste of manpower and time.

In order to solve the above technical problems, this application is implemented as follows:

A sound insulation structure is provided, which includes an expansion joint bracket and a sound insulation board. The expansion joint bracket has a bottom plate, a first convex portion, and a second convex portion. The first convex part and the second convex part are arranged on the bottom plate, the first convex part and the second convex part are opposite to each other, and the first convex part, the second convex part and the bottom plate form an accommodating space. The sound insulation board is arranged on the bottom plate, and a part of the sound insulation board is located in the accommodating space.

In the embodiment of the present application, the sound insulation structure is divided into two parts, one is a sound insulation board for sound insulation, and the other is an expansion joint bracket for positioning. Among them, the sound insulation board can be assembled in advance and used as a wall with sound insulation function.

Please refer to FIG. 1 and FIG. 2, which are respectively a cross-sectional view and a perspective view of a sound insulation structure according to an embodiment of the present application. As shown in the figure, the soundproof structure includes an expansion joint bracket 1A and a soundproof board 2A. The expansion joint bracket 1A is used to carry the sound insulation board 2A, and the size of the expansion joint bracket 1A can be configured according to actual conditions. Generally speaking, when laying wooden floors or elastic mats (hereinafter referred to as "floor structure"), a certain gap (or "expansion joint") is usually left at the corner of the wall. Since the floor structures are connected to each other by snapping or embedding, when the temperature changes and the heat expands and contracts, the total area of the floor structure will increase or decrease. The gap provides a space for the floor structure to expand and contract to avoid warping of the floor. Therefore, the expansion joint bracket 1A can be adjusted to match the size of the gap left when laying the floor or the size of the gap expected to be left. It should be noted that the above-mentioned wooden floor or elastic floor mat is only an example. In actual situations, expansion joints can be installed on marble floors, cement floors, or floors recognized by those with ordinary knowledge in the technical field. In addition, the sound insulation board 2A is a wall with excellent sound insulation effect, which can achieve light weight and sound insulation effect according to the method described below.

In order to make the technical features of the present application more obvious, the various elements and various aspects of the sound insulation structure will be explained in detail below.

Please refer to FIGS. 3 and 4, which are respectively a cross-sectional view and a perspective view of an expansion joint bracket of an embodiment of the present application. As shown in the figure, the expansion joint bracket 1A has a bottom plate 10, a first convex portion 11 and a second convex portion 12. The first convex portion 11 and the second convex portion 12 are disposed on the bottom plate 10, and the first convex portion 11 and the second convex portion 12 are opposite to each other. The first convex portion 11, the second convex portion 12 and the bottom plate 10 form an accommodating space 13.

As shown in FIG. 4, the bottom plate 10 has a first thickness t1 and a first width w1, which can be set according to the surrounding floor structure. For example, in some embodiments, the bottom plate 10 may partially overlap the surrounding floor structure (for example, a wooden floor). That is, the floor structure covers a part of the bottom plate 10. In this case, the first thickness t1 of the bottom plate 10 may be small to prevent the part of the floor structure covering the bottom plate 10 from being significantly inclined. Alternatively, the bottom plate 10 may not overlap with the surrounding floor structure at all. That is, the sides of the floor structure are attached to the sides of the bottom plate 10 (ie, the first side wall 10A and/or the second side wall 10B in FIG. 3), or are separated by a short distance. In this case, the first thickness t1 of the bottom plate 10 may be equal to or slightly smaller than the thickness of the floor structure, so that there will be no significant height difference between the expansion joint bracket 1A and the floor structure.

When the floor structure covers a part of the bottom plate 10, the first width w1 of the bottom plate 10 may be larger, so that the bottom plate 10 overlaps with the surrounding floor structure more. In this way, the bottom plate 10 is pressed by the floor structure and is not easy to slide, which can improve the stability of the expansion joint bracket 1A. On the other hand, when the floor structure does not cover the bottom plate 10, the first width w1 of the bottom plate 10 can be adjusted in accordance with the floor structure, so that the sides of the bottom plate 10 can be attached to the sides of the floor structure, or a gap is left for each other Retractable.

The first convex portion 11 and the second convex portion 12 are disposed on the bottom plate 10. The first convex portion 11 has a second thickness t2, and the second convex portion 12 has a third thickness t3. Wherein, the second thickness t2 of the first convex portion 11 and the third thickness t3 of the second convex portion 12 may be thicker, so as to improve the supporting effect of the expansion joint bracket 1A. In addition, since the expansion joint bracket 1A may contain a sound insulation material (which will be mentioned below), when the second thickness t2 of the first convex portion 11 and the third thickness t3 of the second convex portion 12 are thicker , The sound insulation effect of the expansion joint bracket 1A can also be improved.

As shown in FIG. 3, the first convex portion 11 and the second convex portion 12 are separated by a first distance d1, the first convex portion 11 and the first side wall 10A of the bottom plate 10 are separated by a second distance d2, and the second convex portion There is a third distance d3 between the portion 12 and the second side wall 10B of the bottom plate 10. Among them, the first distance d1, the second distance d2, and the third distance d3 can be configured according to actual conditions. For example, the first distance d1 is related to the thickness of the sound insulation board 2A. When the sound insulation board 2A is thicker, the first distance d1 between the first convex portion 11 and the second convex portion 12 becomes larger. When the first width w1 of the bottom plate 10 is unchanged, the larger the first distance d1, the smaller the second distance d2 and the third distance d3.

In addition, the first convex portion 11 and the second convex portion 12 may sandwich a 90 degree angle with the bottom plate 10. However, this application is not limited to this. In some embodiments, the first convex portion 11 and the second convex portion 12 may have an angle of 90±15 degrees with the bottom plate 10 to match the non-horizontal ground or the special-shaped sound insulation board 2A.

In practical applications, the first convex portion 11 and the second convex portion 12 can be used as positioning tools when installing the sound insulation structure. For example, the first convex portion 11 and the second convex portion 12 may further include positioning portions for positioning. The positioning portion protrudes from the first convex portion 11 and the second convex portion 12. The positioning part includes a plurality of sub-positioning parts, and each of the plurality of sub-positioning parts is arranged at equal intervals with each other (for example, two adjacent sub-positioning parts may be adjacent to each other by 10 cm) as a positioning and ruler tool. After the sound insulation structure is installed, the construction personnel can remove the positioning parts on the first protrusion 11 and the second protrusion 12 to maintain the beauty of the sound insulation structure. Compared with the wall without the expansion joint bracket 1A, the expansion joint bracket 1A is used to assist in positioning, which can effectively and quickly allow the construction personnel to install the sound insulation structure and maintain the beautiful appearance of the wall after the construction is completed.

Please refer to FIGS. 5 and 6, which are respectively a cross-sectional view and a perspective view of an expansion joint bracket according to another embodiment of the present application. As shown in the figure, the expansion joint bracket 1B has a bottom plate 10, a first convex portion 11 and a second convex portion 12. In this embodiment, the same component symbols denote the same components in FIGS. 3 to 6, so the related description is omitted.

Compared with the foregoing embodiment, the first convex portion 11 and the second convex portion 12 in this embodiment are respectively located on both sides of the bottom plate 10. That is, there is no distance between the first convex portion 11 and the first side wall 10A of the bottom plate 10, and there is no distance between the second convex portion 12 and the second side wall 10B of the bottom plate 10. That is, when the expansion joint bracket 1B in this embodiment is installed, the bottom plate 10 will not be covered by the floor structure.

It should be noted that the above two embodiments are only examples. In actual use, the first convex portion 11 of the expansion joint bracket can be separated from the first side wall 10A of the bottom plate 10 by a second distance d2, and there is no distance between the second convex portion 12 and the second side wall 10B of the bottom plate 10. Alternatively, there is no distance between the first convex portion 11 of the expansion joint bracket and the first side wall 10A of the bottom plate 10, and the second convex portion 12 and the second side wall 10B of the bottom plate 10 are separated by a third distance d3.

In some embodiments, the material of the expansion joint bracket 1A may include a porous material. Porous materials refer to materials that contain many pores. The large number of two-phase interfaces formed by the multiple pores can hinder the transmission of sound and/or heat energy (for example, be absorbed or diverged irregularly). In this way, the sound insulation effect and heat insulation effect of the sound insulation structure can be further improved. For example, the porous material may be styrofoam, organic fiber material, inorganic fiber material, foam, glass wool, rock wool, mineral wool, urea resin or polyurethane, but is not limited thereto.

In some embodiments, the expansion joint bracket 1A may be a multilayer structure. For example, the expansion joint bracket 1A may include a first sub-layer and a second sub-layer.
