[0030] In order to make the purpose, technical solution and advantages of the utility model more clear, the utility model is further described in detail in combination with the embodiments below. It should be understood that the specific embodiments described here are only used to explain the utility model, and are not used to limit the utility model.

[0031] See also Figures 1 to 10 A container with sound insulation function includes a container body 7, one end of the container body 7 is hinged with a container door 5, a sound insulation layer 1 is arranged in the container body 7, and the sound insulation layer 1 is fixed on the top wall, two side walls and the other end wall of the container body 7 through a keel 2.

[0032] The sound insulation layer 1 includes rock wool 3 and a mesh plate 4. In the utility model, the thickness of the rock wool 3 is 40 mm, the thickness of the mesh plate 4 is 2 mm, and the mesh diameter is 1 mm. The mesh plate is an acoustic material that can weaken the propagation of sound waves. The sound insulation principle is to use a series of concentric circles or square holes on the surface of the plate to suppress the propagation of sound waves by air resonance. In the process of sound transmission, sound waves will enter the holes, and under the action of reflection and interference, the sound waves will be attenuated and destructively interfered, thereby reducing noise.

[0033] The mesh plate 4 is covered on the rock wool 3 and fixedly connected to the keel 2; a plurality of keels 2 are provided and are welded and fixed in the side wall of the container body, and the distribution spacing of the keel 2 is adapted to the size of the rock wool 3, so that the entire rock wool 3 is just laid in the mesh welded by the keel 2; during welding, the center line of the welded keel 2 is made to coincide with the splicing line of the two pieces of rock wool 3 through pre-measurement of the size; then the mesh plate 4 is covered on the rock wool 3, and the mesh plate 4 is fixed to the keel 2 with screws to complete the fixation of the sound insulation layer 1 to the inner wall of the container body 7.

[0034] As one aspect of the present invention, the keel 2 and the inner wall of the container body 7 can be welded in two different ways:

[0035] In the first welding method, the wide side of the keel 2 is welded to the inner wall of the container body 7, and the two side surfaces of the keel 2 are in contact with the rock wool 3, and then the mesh plate 4 is screwed to the keel 2, see Figure 3 ;

[0036] In the second embodiment, the long side of the keel 2 is welded to the inner wall of the container body 7, and the intersection of the rock wool 3 and the keel 2 is cut, which can accommodate 1 / 2 of the keel 2. After the notches of the rock wool 3 on both sides cover the keel 2, the mesh plate 4 is screwed to the keel 2. Fig.10 .

[0037] Preferably, a corner fixing piece is welded and fixed at a corner between two adjacent side walls in the container body 7, and the corner fixing piece is used to fix the sound insulation layer 1 at the corner of the inner wall of the container body 7; due to the structure of the corner between two adjacent side walls in the container body 7, the sound insulation layer 1 is difficult to be fixed at the corner position; further, according to the specific internal structure of the container body 7, the corner fixing piece 6 is set to two types.

[0038] One of them is a Z-shaped part 6, which is formed by bending a steel plate. The Z-shaped part 6 includes a first parallel section 61, a connecting section 63 and a second parallel section 62. The first parallel section 61 is parallel to the second parallel section 62, and the connecting section 63 is vertically connected between the first parallel section 61 and the second parallel section 62.

[0039] The Z-shaped member 6 is suitable for the case where a corner column 8 is provided between adjacent two side walls of the container body 7; one end of the first parallel section 61 or the second parallel section 62 of the Z-shaped member 6 is welded to the corner column 8, and before welding, the second parallel section 62 or the first parallel section 61 is arranged parallel to one of the inner walls of the container body 7, and is welded in a manner that the second parallel section 62 or the first parallel section 61 is close to the side wall; in order to facilitate the installation of the sound insulation layer 1, the width of the connecting section 63 is equal to the side length of the corner column 8 minus the thickness of the rock wool 3 The width of the second parallel section 62 and the first parallel section 61 is equal to the thickness of the rock wool 3; after the Z-shaped member 6 is welded to the corner column 8, the rock wool 3 is inserted between the Z-shaped member 6 and the parallel side wall, and then covers the mesh plate 4, and the mesh plate 4 is fixed to the second parallel section 62 or the first parallel section 61 with screws; the rock wool 3 on the other side wall is in contact with the side of the first parallel section 61 or the second parallel section 62, the mesh plate 4 covers the connecting section 63 and the rock wool 3, and the mesh plate 4 and the connecting section 63 are fixed with screws.

[0040] The other one is an L-shaped piece 9, which is formed by bending a steel plate and is suitable for the situation where no corner column 8 is provided between the adjacent two side walls in the container body 7; after the sound insulation layer 1 on the adjacent two side walls is laid, the outer top corner of the L-shaped piece 9 is placed on the sound insulation layer 1 on the adjacent two side walls, and the L-shaped piece 9 is fixed to the mesh plate 4 with screws.

[0041] The following describes the laying process of the sound insulation layer in the utility model:

[0042] First, fix the keel; determine the installation position of the keel in the top wall, two side walls and one end wall of the container body according to the size of the rock wool. Intermittent welding is used between the keel and the inner wall, with a welding spacing of 30mm, and then nailed to fix after welding;

[0043] Second, if there are corner posts between adjacent side walls in the container body, a Z-shaped piece is welded on the corner post so that the Z-shaped piece is parallel to and close to one of the side walls;

[0044] Third, prefabricate the sound insulation layer. There are two ways to prefabricate the sound insulation layer;

[0045] The first method is to bond the rock wool to the mesh plate first, and reserve the keel position between the rock wool;

[0046] The second method is to first bond the rock wool to the grid surrounded by the keel on the inner wall of the container, and then cover it with a mesh plate;

[0047] Fourth, fix the sound insulation layer; after prefabricating the sound insulation layer in the above two ways, fix the mesh plate on the keel with screws to complete the fixation of the sound insulation layer and the keel;

[0048] Finally, if there are corner columns between adjacent side walls in the container body, the mesh plate and the Z-shaped piece are fixed with screws; if there are no corner columns between adjacent side walls in the container body, the corner position is covered with an L-shaped piece, and the L-shaped piece is fixed to the mesh plate with screws.

[0049] Complete the laying of the sound insulation layer.

[0050] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
