Description

Technical Field

[0001] This invention relates to a plug for sound insulation and vibration reduction in building installation engineering, and particularly to a sound insulation plug for mounting brackets. Background Technology

[0002] Mounting brackets are frequently used in building installation services. They are typically metal sheet profiles with a long, slender mounting surface extending longitudinally. Mounting brackets come in a wide variety of types, including C-shaped, U-shaped, L-shaped, or closed rectangular sections, depending on the shape of their cross-section, providing possibilities for connecting various elements. In many cases, assembled bracket systems are suspended from the ceiling, for example, as supports for cable reels, pipes, and ventilation ducts.

[0003] In many applications of mounting brackets, it is necessary to decouple the brackets from the load-bearing components connected to or resting on them. This is the case, for example, when placing rectangular ventilation ducts on a mounting bracket system. Ventilation ducts are piping systems used for air transport and distribution, widely used in areas such as workshop air conditioning. However, during use, the air inside the ducts vibrates due to the impact of the air during transport, affecting the stability of the fixed duct supports. Furthermore, ventilation ducts generate noise during operation; without sound insulation, the noise from the fans within the ducts will be transmitted, potentially causing noise pollution within the building and affecting the work of employees.

[0004] Therefore, sound-insulating inserts are typically placed between mounting brackets and ventilation ducts to reduce vibration and noise. EP0865024B1 discloses a sound-insulating insert for a mounting bracket with a C-shaped cross-sectional profile. This insert includes a support portion having a bottom surface and downwardly extending longitudinal edges. Ridges are formed on its support surface, extending parallel to each other in the longitudinal direction of the support portion. Feet are integrally formed on the support portion, each having a shoulder on one of its two longitudinal sides opposite the bottom surface of the support portion. In the assembled state, the feet are arranged within the C-shaped bracket, with the shoulders abutting the rear longitudinal edges of the bracket opening.

[0005] However, such soundproofing inserts can only be installed within a C-shaped bracket via their feet, meaning they can only be installed on the side of the C-shaped bracket with the longitudinally extending slot. But in actual working conditions, ventilation ducts cannot always be installed on the slotted side of the C-shaped bracket. In fact, either side of the C-shaped bracket may contact or support the ventilation duct; therefore, existing soundproofing inserts have the problem of not being applicable to any mounting surface of the C-shaped bracket. Furthermore, the mounting bracket is not necessarily a C-shaped bracket; it can also be a bracket with a closed rectangular cross-section, an L-shaped bracket, or a U-shaped bracket. Existing soundproofing inserts will not be compatible with mounting brackets other than the C-shaped type. Summary of the Invention

[0006] The technical problem to be solved by the present invention is to provide a sound insulation plug for mounting brackets, which can be adapted to various types of mounting brackets and to multiple mounting surfaces of the mounting brackets.

[0007] To solve the above-mentioned technical problems, the present invention adopts the following solution:

[0008] A soundproof insert for a mounting bracket, the mounting bracket including at least one longitudinally extending mounting surface having at least one longitudinal opening, the soundproof insert being made of an elastic material, including a longitudinally extending base having a bottom surface and a support surface opposite the bottom surface, and a foot element extending downward from the bottom surface, the base including a ridge, the upper surface of the ridge at least partially forming the support surface, the longitudinal side of the ridge having shear portions to form a shoulder at the longitudinal side edge of the ridge; the ridge can be placed in the longitudinal opening of the mounting bracket, wherein the shear portions accommodate the longitudinal edge of the mounting bracket adjoining the longitudinal opening, and the shoulder engages behind the longitudinal edge.

[0009] According to a preferred embodiment of the invention, the base further includes a lateral wing extending laterally outward from the ridge, wherein the lower surface of the lateral wing coincides with the bottom surface of the base, and the upper surface of the lateral wing extends laterally outward from the lower end of the shear portion along an arc with gradually increasing height until the upper surface of the lateral wing coincides with the support surface, forming another portion of the support surface. Preferably, the edge of the lateral wing includes a chamfered surface inclined downward relative to the support surface, and a flange protruding downward from the bottom surface. More preferably, the lateral wing is provided with a through hole or opening for weakening the strength of the elastic material.

[0010] According to another preferred embodiment of the invention, the shoulder has a sloping side that is inclined downward relative to the supporting surface.

[0011] Preferably, the ridge has a region where the elastic material strength is reduced. More preferably, the region where the strength is reduced is formed by removing part of the material from the support surface of the ridge to create an arc-shaped concave surface.

[0012] According to another preferred embodiment of the present invention, the foot element includes two opposing downwardly extending feet, and when the mounting bracket has a C-shaped or U-shaped cross-sectional shape, it has a slot extending along the entire length of the mounting bracket, and the feet can be placed in the slot.

[0013] The leg has a hook at its end that faces the bottom surface. When the mounting bracket has a C-shaped cross-section, the hook engages with the end of the edge of the longitudinal slot of the C-shaped mounting bracket.

[0014] Preferably, a lateral groove is provided between the support leg and the bottom surface. When the mounting bracket has a U-shaped cross-section, the edge of the longitudinal slot of the U-shaped mounting bracket is engaged in the groove.

[0015] According to the above technical solution, the soundproofing insert of the present invention can be adapted to various types of mounting brackets. For example, when the mounting bracket is a C-shaped bracket, the soundproofing insert of the present invention can be placed in the longitudinal slot of the C-shaped bracket extending along its entire length through the foot element. Preferably, the foot element also has a hook portion that can hook onto the end of the side wall of the C-shape, so that the soundproofing insert can be stably and firmly installed on the side of the C-shaped bracket with the slot. When the mounting surface of the C-shaped bracket is not the side with the longitudinal slot, but another side or bottom surface, the soundproofing insert of the present invention can be placed in the longitudinal opening on the side or bottom surface of the mounting bracket through the elastic deformation of the ridge. At this time, the shear portion accommodates the longitudinal edge of the mounting bracket that meets the longitudinal opening, and the shoulder portion engages behind the longitudinal edge. Thus, the soundproofing insert of the present invention can be installed on any mounting surface of the mounting bracket, and has extremely wide application and adaptability.

[0016] Moreover, when the mounting bracket has other cross-sectional shapes, such as a closed rectangle, an L-shape, or a U-shape, as long as the mounting surface of the mounting bracket has several longitudinal openings, the sound insulation plug of the present invention can be easily and reliably placed on the mounting surface of the mounting bracket by inserting the ridge into the longitudinal openings, which provides convenience for users and also greatly reduces construction costs.

[0017] The soundproofing insert of this invention has a simple and compact structure. Through precise structural design, the supporting surface formed by the ridge and the supporting surface formed by the side wings work together to provide strong support between the load and the mounting surface of the mounting bracket, resulting in excellent weight distribution of the load-bearing components. If the load-bearing component (e.g., a ventilation duct) supported by the soundproofing insert experiences lateral displacement, this reduces or eliminates the possibility of the soundproofing insert being unintentionally pulled off the mounting bracket. When the soundproofing insert of this invention is installed in the longitudinal opening of other types of brackets, the foot elements will act as support for the load-bearing components. These foot elements typically have higher elasticity and support height, thereby improving sound decoupling between the ventilation duct and the mounting bracket, achieving superior sound insulation.

[0024] Figure 6 This is a schematic diagram of a sound insulation plug installed on an L-shaped mounting bracket along a transverse section according to another embodiment of the present invention. Detailed Implementation

[0025] Below, we will refer to Figures 1 to 6 A soundproofing insert for mounting brackets according to the present invention is described.

[0026] Figure 1The invention illustrates a sound-insulating insert 100 for a mounting bracket, typically mounted on the mounting bracket to reduce noise and / or vibration that may be generated by load-bearing components (e.g., ventilation ducts) supported by the mounting bracket.

[0027] The mounting brackets are identified by numbers starting with 2. Mounting brackets are typically long, longitudinally extending steel bars, and there are many types. Based on their different transverse cross-sectional shapes, they are classified as follows: Figure 2 The C-type shown in the figure Figure 3 and Figure 4 The U-shape shown Figure 5 The rectangular shape shown, and Figure 6 The L-shaped type shown is an example. It should be understood that the mounting bracket 200 of the present invention is not limited to the exemplary embodiments described above; regardless of the shape of the transverse cross-section of the mounting bracket, it generally has longitudinally extending, elongated sides to provide support or assembly. For example, as... Figure 2 The C-type mounting bracket shown has a cross-sectional shape resembling the letter C. It includes two opposing sides 201 and a bottom surface 202 perpendicular to the sides 201. Opposite to the bottom surface is a slot 203 extending integrally along its longitudinal length, i.e., the opening portion of the C. The edge 204 connecting with the slot 203 has an inwardly bent end 205. Furthermore, at least one longitudinal opening 206 is provided on the sides 201 and / or the bottom surface 202; preferably, the longitudinal opening 206 is an elongated elliptical hole. The longitudinal opening 206 serves to reduce the overall weight of the bracket and to facilitate the combination and installation of the bracket. Depending on the space where the mounting bracket is applied and the matching parts, any surface of the mounting bracket, such as the surface with the slot, the bottom surface, or the side surface, can serve as the mounting surface for supporting load-bearing components. The above is a simplified description of the structure of the C-type mounting bracket. Similarly, for mounting brackets with other cross-sectional shapes, the mounting surface may also be a side surface, a bottom surface, or a surface with a slot. Further detailed descriptions will follow with reference to the accompanying drawings and embodiments.

[0028] According to one embodiment of the invention, the sound-insulating insert 100 is made of an elastic material. Elastic materials have proven to be particularly suitable as materials for sound-insulating inserts. The sound-insulating insert 100 can be made of a suitable elastic material based on its specific sound absorption and elasticity properties. Preferably, the sound-insulating insert 100 is made of rubber.

[0029] refer to Figure 1The soundproofing insert 100 includes a longitudinally extending base 101 and a foot element 109 extending downward from the base. Preferably, the soundproofing insert 100 extends longitudinally with the same transverse cross-sectional shape, and its longitudinal extension length should be adapted to the length of a pre-drilled longitudinal opening 206 on the mounting surface of the mounting bracket. Preferably, the longitudinal extension length of the soundproofing insert 100 is substantially equal to the length of the longitudinal opening 206. The base has a bottom surface 102 and a support surface 103 opposite to the bottom surface. When the foot element 109 of the soundproofing insert is inserted into the mounting bracket, as... Figure 2 and Figure 3 As shown, the bottom surface 102 abuts against the edge 204 of the longitudinal slot 203 of the C-shaped or U-shaped mounting bracket. The support surface 103 supports the load-bearing component of the mounting bracket, such as the bottom surface of a ventilation duct (not shown). In other words, the base 101 forms a gap between the load-bearing component and the mounting surface of the mounting bracket. Since the sound insulation plug 100 is made of elastic material, it can effectively reduce the vibration and / or noise that the load-bearing component such as the ventilation duct may transmit to the mounting bracket 200.

[0030] The base 101 includes a ridge 105, which is a flat, elongated strip located approximately at the center of the base and extending longitudinally. The upper surface of the ridge 105 at least partially forms the support surface 103. Preferably, the support surface formed by the ridge has a weakened area, making it easier for the ridge 105 to elastically deform and be inserted into the longitudinal opening 206 of the mounting bracket. More preferably, the weakened area is formed by removing a portion of material from the support surface of the ridge to create an arc-shaped concave surface 110. This ensures that the ridge 105 has sufficient strength to support the load while also allowing for easy elastic deformation of the ridge to facilitate placement into the longitudinal opening 206.

[0031] A shear portion 107 is provided on the longitudinal side of the ridge, thereby forming a shoulder portion 108 at the longitudinal side edge of the ridge. Figures 4 to 6As shown, the ridge 105 is positioned in the longitudinal opening 202 of the mounting bracket in its installed state, and the shear portion 107 accommodates the longitudinal edge 207 of the mounting bracket that borders the longitudinal opening 206. The shoulder 108 engages with the rear of the longitudinal edge 207 of the mounting bracket that borders the longitudinal opening 206. Thus, through the combined action of the shoulder 108 and the shear portion 107, the sound insulation insert 100 is securely attached to the mounting surface of the mounting bracket, preventing it from dislodging from the longitudinal opening 206 of the mounting bracket even when the load component vibrates and causes lateral displacement. The foot element 109 provides strong vertical support to the load component, while the shoulder 108 and shear portion 107 effectively alleviate lateral pressure caused by load vibration in the left-right direction. Preferably, the shoulder 108 has a downwardly inclined side surface 111 relative to the support surface, making it easier for the ridge 105 to be inserted into the longitudinal opening 206 of the mounting bracket.

[0032] The base 101 also includes side wings 104 extending laterally outward along the bottom surface. Preferably, there are two side wings 104, each extending laterally outward from the ridge 105, forming two side wings symmetrically arranged along the ridge to ensure the balance of the sound insulation plug during installation and use. The lower surface of the side wing 104 coincides with the bottom surface of the base 101, that is, the bottom surface of the side wing 104 is part of the bottom surface of the base. The upper surface of the side wing 104, opposite to the bottom surface, extends laterally outward from the lower end of the shear portion 107. The upper surface of the side wing extends along an arc with gradually increasing height until the upper surface of the side wing coincides with the support surface 103. Therefore, the upper surface of the side wing 103 constitutes another part of the support surface 103. Thus, when the sound insulation insert is placed in the slot 203 of the C-shaped or U-shaped bracket, the support surface 103 formed by the ridge 105 and the two side wings 104 can provide stable support for the load-bearing components, thereby more effectively decoupling noise and reducing vibration.

[0033] The side wing 104 also includes a chamfered surface 113 that slopes downward relative to the support surface. This chamfered surface 113 is located at the lateral edge of the side wing and slopes downward from the outer edge of the support surface 103, which forms another portion of the side wing. The chamfered surface 113 reduces the overall material usage of the sound insulation insert, which helps control costs and simplifies the molding process. More preferably, the side wing includes a flange 114 that protrudes downward relative to the bottom surface. The flange 114 is located at the outermost lateral position of the bottom surface and can engage with the upper end of the side surface 201 of the mounting bracket, thereby making the installation and fixation between the sound insulation insert and the mounting bracket more reliable. When the mounting surface of the mounting bracket is its narrower side surface 201, for example, as... Figure 5 and Figure 6As shown, the area between the side wings and the spine, that is, the part of the upper surface of the side wings that gradually increases from the shear section curve, can also serve to clamp the mounting surface of the bracket.

[0034] Preferably, the side wing 104 is provided with through holes 112 or openings, or other forms of strength-reducing areas, for weakening the strength of the elastic material. Preferably, the through holes 112 are located below another part of the support surface formed on the upper surface of the side wing, because this part is the highest part of the side wing, that is, the thickest part of the elastic material. Therefore, removing part of the elastic material to form a longitudinally extending through hole allows the side wing to deform appropriately under pressure. In particular, when subjected to shear force, the through holes 112 formed in the side wing can effectively counteract the vibration or displacement caused by the shear force.

[0035] According to a preferred embodiment of the present invention, the foot element 109 includes two opposing downwardly extending feet 115. When the mounting bracket has a C-shaped or U-shaped cross-section, it has a slot 203 extending along the entire length of the bracket, and the feet 115 are placed within the slot 203 in the installed state. Preferably, the feet 115 have hooks 116 at their ends opposite to the bottom surface. When the mounting bracket has a C-shaped cross-section, the hooks 116 respectively hook onto the two ends 205 of the C-shape of the mounting bracket, so that the sound insulation plug 100 is more reliably and stably fixed within the slot of the C-shaped bracket.

[0036] More preferably, a lateral groove 117 is provided between the support leg 109 and the bottom surface 102. When the mounting bracket has a U-shaped cross-section, the end of the edge 204 that connects with the slot 203 is engaged in the groove 117. This helps to improve the stability and reliability of the sound insulation plug installed in the mounting bracket.

[0037] Preferably, the foot element 109 and the base 101 are integrally formed. Alternatively, the base and foot element of the present invention can be composed of elastic materials with different properties. For example, the base can be made of a material that is slightly harder than the foot element.

[0038] As described above, the soundproofing insert of the present invention can be adapted to various types of mounting brackets and any mounting surface of the mounting brackets. For example, when the mounting bracket is a C-type or U-type bracket, such as Figure 2 and Figure 3 As shown, the soundproofing insert 100 of the present invention can be placed inside the slot 203 of a C-shaped or U-shaped bracket via the foot element 109. When the mounting surface of the mounting bracket is not the side with the slot 203, for example, as... Figures 4 to 6As shown, when the mounting surface is the bottom or side of the mounting bracket, the sound insulation insert 100 of the present invention can be placed in the longitudinal opening 206 of the mounting surface through the elastic deformation of the ridge 105. Therefore, the sound insulation insert of the present invention has extremely wide application scenarios and adaptability, providing convenience for users and greatly reducing construction costs.

[0039] The soundproofing insert of the present invention has a simple and compact structure. In particular, when the soundproofing insert is installed in the longitudinal opening 206 of the mounting bracket via the ridge 105, the support surface 103 formed by the ridge 105 and the side wings 104 provides strong support between the load and the mounting surface of the mounting bracket, effectively distributing the weight of the load component. The shearing portion 107 and the shoulder portion 108 clamp the longitudinal edge of the mounting bracket where it meets the longitudinal opening, reducing or eliminating the possibility of the soundproofing insert being unintentionally pulled off the mounting surface of the mounting bracket. The foot element 109 provides support; it typically has a higher support height and better elasticity, thereby improving the decoupling of sound between the load component (such as the ventilation duct) and the mounting bracket, resulting in superior sound insulation.

[0040] As mentioned above, although exemplary embodiments of the present invention have been described in the specification with reference to the accompanying drawings, the present invention is not limited to the specific embodiments described above, and there may be many other embodiments. The scope of the present invention should be defined by the claims and their equivalents.
