Description

Technical Field

[0001] The present application relates to the technical field of noise reduction structures, and in particular to a noise reduction structure for walls of old buildings. Background Art

[0002] For the living space of old buildings, building sound insulation mainly relies on the walls of the building itself, and the sound insulation effect is poor. Therefore, in order to improve the sound insulation effect of old buildings, it is generally necessary to add a new sound insulation measure on the wall. Most of the existing sound insulation measures are constructed using frames, sound insulation cotton boards and sound insulation felts. The frames are constructed on the walls, but the existing frames are C-shaped (such as a sound insulation wall board disclosed in announcement number: CN205907898U). After the frame construction is completed, the sound insulation cotton board needs to be stuck in the frame, but the C-shaped frame can only allow the middle two sides or one side of the four sides of the sound insulation board to be stuck in the frame, resulting in loose fixation of the sound insulation board, which increases the difficulty of subsequent construction of the sound insulation felt and makes it difficult to lay the sound insulation felt smoothly. This will cause wrinkles and bubbles to appear on the sound insulation felt after construction, affecting the sound insulation effect. Utility Model Content

[0003] In order to ensure that the sound insulation cotton can be stably fixed on the wall, facilitate subsequent construction, thereby improving construction quality and further improving the sound insulation effect, the present application provides a noise reduction structure for the wall of an old building.

[0004] The present application provides a noise reduction structure for old building walls using the following technical solutions:

[0011] By adopting the above technical solution, it is only necessary to buckle the first frame bar and the second frame bar, and then press the second frame bar. The raised portion of the second frame bar slides along the guide bevel block and the arc block undergoes elastic deformation. When the raised portion disengages from the guide bevel block, the arc block recovers its deformation and the raised portion is clamped in the arc groove of the arc block, which facilitates the installation of the first frame bar and the second frame bar.

[0019] 2. Simply interlock the first and second frame bars, then press the second frame bar.

The raised portion 42 is arranged along the length direction of the second frame bar 3, and the raised portion 42 can be snapped into the corresponding arc block 41;

[0035] A plurality of first frame bars 2 are vertically mounted on the wall and arranged in a plurality of rows. A horizontally mounted first frame bar 2 is further arranged between the first frame bars 2 in adjacent rows. Both ends of the horizontally mounted first frame bars 2 are spliced ​​with the vertically mounted first frame bars 2.

[0036] Side limiting plates 31 are integrally formed on both sides of the bottom plate of the second frame bar 3. The side limiting plates 31 of the second frame bar 3 placed vertically are flush with both ends of the bottom plate, and the side limiting plates 31 of the second frame bar 3 placed horizontally are shorter than the length of the second frame bar 3;

[0037] The first frame bars 2 are arranged into a plurality of columns and rows to separate a plurality of installation frames for installing the sound insulation acoustic wool panels 1 on the wall. The four sides of the sound insulation acoustic wool panels 1 facing away from the wall are all stuck in the grooves surrounded by the first frame bars 2, the second frame bars 3, the side limit plates 31 and the wall.

[0038] A sound insulation felt 5 is commonly provided on the side of the sound insulation acoustic cotton board 1 and the second frame bar 3 facing away from the wall. The sound insulation felt 5 is coated with glue and affixed to the sound insulation acoustic cotton board 1. A decorative layer 6 is provided on the sound insulation felt 5. The decorative layer 6 includes a first mounting plate 61. The first mounting plate 61 is mounted on the side of the sound insulation felt 5 facing away from the wall by screws. The screws pass through the bottom plate of the second frame bar 3. The first mounting plate 61 is coated with a latex paint layer 62. The first mounting plate 61 is a gypsum board. The joints of the sound insulation felt 5 and the joints of the first mounting plate 61 are staggered, and the first mounting plate 61 is poured with sound insulation sealing glue.

A second mounting plate 7 is fitted on the side of the sound insulation acoustic cotton board 1 facing away from the wall. Connecting strips 71 are arranged around the second mounting plate 7. Four connecting strips 71 are spliced ​​end to end to form a frame. The connecting strips 71 are inserted into the mounting groove 311, and the side of the second mounting plate 7 facing away from the wall is flush with the second frame bar 3.

[0042] When the sound insulation acoustic cotton board 1 is pushed into the C-shaped frame formed by the three adjacent side limit plates 31, the plug-in strip 71 can be inserted into the installation groove 311, and the second installation plate 7 can be pushed so that the second installation plate 7 is pushed into the C-shaped frame formed by the three adjacent side limit plates 31, which facilitates the installation of the second installation plate 7. The second installation plate 7 is flush with the second skeleton bar 3, providing a flat construction surface for the sound insulation felt 5, further reducing the occurrence of wrinkles and bubbles in the sound insulation felt 5 during the construction process, and is conducive to improving the construction quality.
