Description

Technical Field

[0001] The utility model belongs to the technical field of building decoration, and particularly relates to an off-wall perforated aluminum plate wall sound-absorbing cotton installation structure. Background Art

[0002] In the current building decoration industry, the common way to install wall sound-absorbing cotton is light steel keel partition wall. This type of partition wall uses light steel keel as the skeleton, and uses paper-faced gypsum board, calcium silicate board, artificial wood board, cement fiber board, etc. as wall panels. The inside of both sides is fully covered with sound-absorbing and fireproof cotton to enhance the sound insulation effect. Modern industrial equipment venues mostly use assembly technology, with metal keels as the skeleton, and use perforated sound-absorbing aluminum panels as wall panels. The aluminum panels are filled with rock wool to meet the needs of sound insulation and noise reduction.

[0003] Although these technologies provide effective sound insulation, they have some problems and disadvantages that cannot be ignored. First, when rock wool is in direct contact with metal keels, friction is easily generated during the vibration sound absorption process, resulting in mechanical wear of the rock wool. This wear may cause the rock wool to loosen or even fall off, increasing safety risks. In addition, when rock wool is attached to aluminum plates, due to its large thickness and thermal expansion characteristics, once it is deformed by heat, it may cause the aluminum plate to bulge, affecting the overall appearance and structural stability of the wall.

[0032] like Figure 1 to Figure 2 As shown, in an illustrative embodiment of the off-wall perforated aluminum plate wall sound-absorbing cotton installation structure of the utility model, the off-wall perforated aluminum plate wall sound-absorbing cotton installation structure includes a main keel 1, a connecting piece 2, an anti-dumping keel 3, an installation clamp 4, rock wool 5 and a perforated aluminum plate 6.

[0033] The connecting member 2 comprises a first connecting plate 21 and a second connecting plate 22 . The second connecting plate 22 is vertically connected to the rear end of the first connecting plate 21 . The second connecting plate 22 is attached to the surface of the wall 7 and fixedly connected thereto by expansion bolts 8 .

[0034] The main keel 1 is arranged vertically and presents a U-shaped structure with an opening facing backward. There are two connecting parts 2, and the main keel 1 is located between the two connecting parts 2. The left and right sides of the main keel 1 are fixedly connected to the first connecting plate 21 of the corresponding connecting part 2 through the first mounting bolt 91, and the outer side surfaces of the left and right sides of the main keel 1 are attached to the inner side surfaces of the front end of the corresponding first connecting plate 21.

[0035] There are two pieces of rock wool 5 , which are respectively located on the left and right sides of the main keel 1 , and both are equipped with anti-dumping keels 3 . The anti-dumping keels 3 are fixed to the corresponding connecting parts 2 by installing the clamps 4 .

[0036] The anti-dumping keel 3 comprises a first keel plate 31, a second keel plate 32 and a third keel plate 33. The first keel plate 31 and the third keel plate 33 are respectively vertically connected to the front end and the rear end of the second keel plate 32, and are respectively located on the left and right sides of the second keel plate 32, so that the anti-dumping keel 3 is Z-shaped. The front side surface of the third keel plate 33 and the outer side surface of the second keel plate 32 are respectively glued and fixed to the rear side surface and the inner side surface of the rock wool 5. The front side surface of the rock wool 5 is flush with the front side surface of the first keel plate 31, and the inner end of the first keel plate 31 has a flange 34 bent backwards.

[0037] The mounting bracket 4 includes a first bracket plate 41 and a second bracket plate 42. The first bracket plate 41 is attached to the outer side of the corresponding first connecting plate 21. The first mounting bolts 91 are all penetrated outwardly through the corresponding first bracket plate 41 to fix it on the first connecting plate 21. One end of the second bracket plate 42 is vertically connected to the front end of the first bracket plate 41, and the other end thereof has a forward-bent pressing edge 43, so that the mounting bracket 4 is Z-shaped. The pressing edge 43 presses and fixes the flange 34 on the outer side of the corresponding first connecting plate 21.

[0038] The rear side of the perforated aluminum plate 6 is attached to the front side of the main keel 1 and is fixedly connected thereto by means of a second mounting bolt 92 .

[0039] The perforated aluminum plate 6 extends to the left and right sides and covers the rock wool 5 on the corresponding side. The front side of the main keel 1 protrudes forward relative to the front ends of the two first connecting plates 21 so that the rear side of the perforated aluminum plate 6 is spaced apart from the corresponding rock wool 5.

[0040] The two connectors 2 are fixed to the wall 7 by the expansion bolts 8, and the main keel 1 is located between the two connectors 2 and fixedly connected to the two connectors 2, so that the two sides of the main keel 1 are supported by the two connectors 2 respectively. The connector 2 not only provides support and fixation for the main keel 1, but also provides an installation position for the mounting bracket 4, so that it is fixed on the first connecting plate 21 of the connector 2. The first mounting bolt 91 connects and fixes the mounting bracket 4, the connector 2 and the main keel 1 together, reducing the number of connecting parts and reducing the structural cost.

[0041] The mounting bracket 4 is located outside the connector 2, separating the connector 2 from the rock wool 5, and the main keel 1 is further away from the rock wool 5, so as to prevent the rock wool 5 from being attached to the connector 2 or the main keel 1, causing friction with the rock wool 5 when it vibrates, and preventing the rock wool 5 from loosening due to wear, thereby maintaining the stable installation of the rock wool 5. In addition, the second keel plate 32 and the third keel plate 33 are both attached to the surface of the rock wool 5, forming a rim at the end of the rock wool 5, protecting and supporting the end of the rock wool 5, avoiding cracking of the corners of the rock wool 5, and further avoiding wear of the rock wool 5 due to contact with other structures, and preventing the rock wool 5 from loosening. Furthermore, the anti-dumping keel 3 can support the rock wool 5 in the front-to-back direction and the left-to-right direction through the second keel plate 32 and the third keel plate 33, preventing the rock wool 5 from tipping over, and improving its stability on the facade.

[0042] The front sides of the rock wool 5 and the anti-tipping keel 3 are flush with the front ends of the connectors 2, and the front end of the main keel 1 protrudes forward relative to the front ends of the two connectors 2, so that the rock wool 5 is spaced apart from the perforated aluminum plate 6 on the front side. When the rock wool 5 expands in the front and rear directions due to the spacing, the rock wool 5 cannot contact the aluminum plate on the front side, thereby preventing the expanded rock wool 5 from pushing up the aluminum plate and causing its deformation, thereby ensuring that the shape of the perforated aluminum plate 6 is stable and maintaining the beauty of the building finish.

[0043] In the above-mentioned schematic embodiment, in the off-wall perforated aluminum plate wall sound-absorbing cotton installation structure, the wall 7 supports the main keel 1 through two connecting members 2, and the anti-dumping keel 3 installed on the rock wool 5 is fixed by the installation clamp 4 installed on the connecting member 2, so that the rock wool 5 is fixed on both sides of the main keel 1, and the installation clamp 4 separates the rock wool 5 from the main keel 1 and the connecting member 2, and the anti-dumping keel 3 wraps the end of the rock wool 5, so as to avoid the end of the rock wool 5 from receiving friction, so that it can remain stable for a long time and avoid it from loosening due to friction caused by vibration, and the main keel 1 protrudes forward relative to the connecting member 2, separating the perforated aluminum plate 6 from the rock wool 5, avoiding the rock wool 5 from expanding due to heat and pushing up the perforated aluminum plate 6, ensuring that the perforated aluminum plate 6 is flat, and solving the problem that the current sound-absorbing cotton installation structure is easy to cause the rock wool 5 to wear and loosen and easy to push up the aluminum plate.

[0044] In some embodiments, the flange 34, the second clip plate 42 and the pressing edge 43 are in a right triangle structure. The triangular structure is relatively stable, so that the pressing edge 43 can firmly press the flange 34, and the installation of the clip 4 can stably fix the anti-dumping keel 3, thereby improving the stability of the installation and fixation of the rock wool 5.

[0045] In some embodiments, the length of the third keel plate 33 is shorter than the corresponding rock wool 5. The third keel plate 33 adopts a shorter length to ensure support and protection for the rock wool 5, while reducing the material used for the anti-dumping keel 3 and reducing the manufacturing cost.

[0046] In some embodiments, the connection between the second keel plate 42 and the edge clamp 43 is attached to the inner side of the second keel plate 32. When the rock wool 5 is heated and expanded, it will not only deform in the front-to-back direction, but also in the left-to-right direction. Due to the contact connection, the rock wool 5 that expands in the left-to-right direction pushes the installation keel 4 toward the connector 2 through the second keel plate 32, so that the edge clamp 43 can more firmly press and fix the flange 34 of the anti-dumping keel 3 on the first connecting plate 21 of the connector 2, thereby improving the stability of the installation of the rock wool 5.

[0047] In some embodiments, the rear side of the rock wool 5 is spaced apart from the wall 7. The space between the rock wool 5 and the wall 7 prevents the rock wool 5 from expanding due to heat and contacting the wall 7. The third keel plate 33 located at the rear side also protects the rear side of the rock wool 5, thereby preventing the rock wool 5 from contacting the wall 7 and causing wear, thereby ensuring that the rock wool 5 is installed stably.

[0048] In some embodiments, the mounting bracket 4 is an elastic member, which after being installed on the connecting member 2, produces elastic deformation to move outward, thereby generating elastic force to more firmly press the flange 34 on the connecting member 2, thereby improving the stability of the installation of the rock wool 5.

[0049] Finally, it should be noted that: the various embodiments in this specification are described in a progressive manner, and each embodiment focuses on the differences from other embodiments. The same or similar parts between the various embodiments can be referenced to each other.

[0050] The above embodiments are only used to illustrate the technical solution of the utility model rather than to limit it. Although the utility model is described in detail with reference to the preferred embodiments, ordinary technicians in the field should understand that the specific implementation methods of the utility model can still be modified or some technical features can be replaced by equivalents without departing from the spirit of the technical solution of the utility model, which should be included in the scope of the technical solution for which protection is requested in the utility model.
