Description

Technical Field

[0001] The invention relates to a modular container corner piece connection structure with sound insulation effect. Background Art

[0002] Modular container buildings are developing rapidly due to their high construction efficiency, high degree of integration, high safety factor and other excellent effects. However, since the container is a steel structure, after the building is built, the sound conduction performance between the steel structures is extremely good, resulting in the sound of the steel structure being hit, which can be transmitted to various parts of the building. Therefore, it is necessary to provide a technical solution to solve the above technical problems. Summary of the invention

[0003] The technical problem to be solved by the present invention is to provide a modular container corner piece connection structure with sound insulation effect.

[0004] In order to solve the above technical problems, the technical solution adopted by the present invention is: a modular container corner fitting connection structure with sound insulation effect, including a sound insulation pad padded between two corner fittings, a first plywood respectively inserted into the holes on the side panels adjacent to the two corner fittings and clamped on both sides of the sound insulation pad, sound insulation plywood respectively arranged on the outside of the two first plywood, a second plywood respectively arranged on the outside of the two sound insulation plywood, and a plurality of bolts passing through the second plywood, the sound insulation plywood, the first plywood and the sound insulation pad, any sound insulation plywood is arranged perpendicular to the first plywood connected thereto, and the two ends of the two sound insulation plywood are respectively abutted against the inner walls of the side panels adjacent to the two corner fittings, the middle parts of the two sound insulation plywood are respectively abutted against the two first plywood, and any second plywood is arranged parallel to the sound insulation plywood abutted thereto and the two ends of the two second plywood are directly opposite to the inner walls of the side panels adjacent to the two corner fittings.

[0005] As a preferred solution, the middle parts of both sides of the sound insulation pad are respectively provided with protrusions protruding outward along the thickness direction, the protrusions are tightly matched with the holes on the side plates of the two corner pieces contacted by the sound insulation pad, and the height of the protrusions is smaller than the depth of the holes.

[0006] As a preferred solution, there is an annular gap between any of the first clamping plates and the inner wall of the hole into which it is inserted, and the first clamping plate does not contact the corner piece.

[0007] The beneficial effect of the present invention is that the direct metal connection between the two corner pieces is separated by the sound insulation pad and the sound insulation clamp, thereby reducing or blocking the sound propagation efficiency, so that the modular containers have a better sound insulation effect after being connected.

[0008] The present invention further utilizes the raised portion on the sound insulation pad to limit the mutual movement of two mutually connected corner pieces, thereby improving the connection stability of the modular container corner piece connection structure.

[0009] The present invention further eliminates the metal connection relationship between two connected corner fittings by making the first clamping plate not contact the corner fittings. Description of the Drawings

[0010] The following further describes in detail the specific embodiments of the present invention with reference to the drawings, where:

[0014] The following describes in detail the specific implementation scheme of the present invention with reference to the drawings.

[0015] As Figure 1 and Figure 2 shown, the modular container corner fitting connection structure with sound insulation effect includes a sound insulation cushion plate 2 padded between two corner fittings 1, first clamping plates 3 respectively inserted into holes 102 on adjacent side plates 101 of the two corner fittings 1 and clamped on both sides of the sound insulation cushion plate 2, sound insulation clamping plates 4 respectively arranged outside the two first clamping plates 3, second clamping plates 5 respectively arranged outside the two sound insulation clamping plates 4, and a bolt 6 passing through the second clamping plate 5, the sound insulation clamping plate 4, the first clamping plate 3 and the sound insulation cushion plate 2. Any sound insulation clamping plate 4 is arranged perpendicular to the first clamping plate 3 connected thereto, and both ends of the two sound insulation clamping plates 4 are in contact with the inner walls of the adjacent side plates 101 of the two corner fittings 1, and the middle parts of the two sound insulation clamping plates 4 are in contact with the two first clamping plates 3 respectively. Any second clamping plate 5 is arranged parallel to the sound insulation clamping plate 4 attached thereto and both ends of the two second clamping plates 5 are facing the inner walls of the adjacent side plates 101 of the two corner fittings 1.

[0016] Convex portions 201 protruding outward in the thickness direction are respectively arranged in the middle of both sides of the sound insulation cushion plate 2. The convex portions 201 are tightly fitted with the holes 102 on the side plates 101 of the two corner fittings 1 in contact with the sound insulation cushion plate 2, and the height of the convex portions 201 is less than the depth of the holes 102.

[0017] There is an annular gap 7 between any first clamping plate 3 and the inner wall of the hole 102 into which it is inserted, and the first clamping plate 3 does not contact the corner fitting 1.

[0018] The sound insulation cushion plate 2 and the sound insulation clamping plate 4 are PVC plates or fluoroplastics plates.

[0019] The working principle of the present invention is as follows: The sound insulation backing plate 2 and the sound insulation clamping plate 4 are used to cut off the direct metal connection relationship between the two corner fittings 1, thereby reducing or blocking the sound propagation efficiency, so that the modular containers have good sound insulation effect after being connected.

[0020] The above embodiments are only used to illustrate the principle and efficacy of the present invention and some applied embodiments, rather than to limit the present invention. It should be pointed out that for those of ordinary skill in the art, without departing from the concept of the present invention, several modifications and improvements can still be made, and these all belong to the protection scope of the present invention.
