Description
Technical Field
The invention relates to an insert for sound insulation and shock absorption in building installation engineering, in particular to a sound insulation insert for an installation bracket.
Background
Mounting brackets are often used in building installation services. The mounting bracket is typically a sheet metal profile having a longitudinally extending elongated mounting surface. The mounting brackets are of a wide variety, e.g. according to their shape in transverse cross section, including C-shaped, U-shaped, L-shaped, or closed rectangular cross section, etc., providing the possibility of connection for a wide variety of connection elements. In many cases, the assembled rack system is suspended from a ceiling, for example, as a support for cable reels, pipes and ventilation ducts.
In many applications of mounting brackets, it is necessary to decouple the bracket from a load member attached to or resting on the bracket. This is the case, for example, when rectangular ventilation ducts are placed on a mounting bracket system. The ventilating duct is a pipeline system for air transportation and distribution, and is widely applied to the fields of workshop air conditioners and the like, however, in the using process of the ventilating duct, the ventilating duct can be impacted by air in the transportation process, so that the ventilating duct vibrates, and the stability of a fixed ventilating duct bracket is affected. Moreover, noise is generated in the operation of the ventilating duct, and if the sound insulation device is not provided, the noise of the fan in the ventilating duct is transmitted, so that the noise pollution in the building can be caused, and the work of staff is influenced.
Therefore, a sound insulating insert for reducing vibration and noise is generally placed between the mounting bracket and the ventilation duct. EP0865024B1 discloses a sound insulating insert for a mounting bracket having a C-shaped cross-sectional profile, which sound insulating insert comprises a support portion having a bottom surface and downwardly stretched longitudinal edges, on the support surface of which strip-shaped ridges are provided, which ridges extend parallel to each other in the longitudinal direction of the support portion. The foot is integrally formed on the support and has on its two longitudinal sides a shoulder which faces the bottom surface of the support and which, in the assembled state, is arranged in the C-shaped bracket, the shoulder being connected behind the longitudinal edge of the bracket opening.
However, such a sound insulation insert can only be mounted by the foot in the C-shaped bracket, and therefore the sound insulation insert can only be mounted on the side of the C-shaped bracket having the longitudinally extending slot. However, in practical working situations, the ventilation duct cannot be mounted constantly on the side of the C-shaped bracket with the slot. In fact, either side of the C-bracket may contact or support the ventilation duct, and thus, the existing sound insulation insert has a problem that it cannot be applied to either mounting surface of the C-bracket. Furthermore, the mounting bracket is not necessarily a C-shaped bracket, but may be a bracket having a closed rectangular cross section or an L-shaped or U-shaped bracket. The existing sound insulation inserts would not be suitable for mounting brackets other than C-type.
Disclosure of Invention
The object of the invention is to provide a sound insulation insert for a mounting bracket which is adaptable to a plurality of types of mounting brackets and which is adaptable to a plurality of mounting surfaces of the mounting brackets.
In order to solve the technical problems, the invention adopts the following scheme:
a sound damping insert for a mounting bracket, said mounting bracket including at least one longitudinally extending mounting surface provided with at least one longitudinal opening, said sound damping insert being made of a resilient material and including a longitudinally extending base portion having a bottom surface and a support surface opposite the bottom surface, and a foot member extending downwardly from said bottom surface, said base portion including a ridge, an upper surface of said ridge at least partially forming said support surface, longitudinal sides of said ridge being provided with a cutout to form a shoulder at longitudinal side edges of said ridge; the ridge may be disposed in a longitudinal opening of the mounting bracket, wherein the cutout accommodates a longitudinal edge of the mounting bracket bordering the longitudinal opening, and the shoulder engages behind the longitudinal edge.
According to a preferred embodiment of the invention, the base further comprises a flank extending laterally outwardly from the ridge, wherein a lower surface of the flank coincides with the bottom surface of the base, and an upper surface of the flank extends laterally outwardly from the lower end of the cutout in increasing arc heights until the upper surface of the flank coincides with the support surface, forming another part of the support surface. Preferably, the edges of the side flaps include a chamfer surface inclined downwardly relative to the support surface, and a flange projecting downwardly from the bottom surface. More preferably, the side flaps are provided with through holes or openings for weakening the elastic material.
According to another preferred embodiment of the invention, the shoulder has a sloping side surface sloping downwards relative to the support surface.
Preferably, the ridge is provided with areas of reduced elastic material strength. More preferably, the area of reduced strength is a concave surface formed by removing part of the material from the support surface formed by the ridge.
According to a further preferred embodiment of the invention, the foot element comprises two opposing downwardly extending feet which when the mounting bracket is of C-or U-shaped cross-sectional shape have a slot extending along the entire mounting bracket length, the feet being receivable within the slot.
The legs have hooks at their ends opposite the bottom surface that hook over the ends of the edges of the longitudinal slots of the C-shaped mounting bracket when the mounting bracket has a C-shaped cross-sectional shape.
Preferably, a lateral groove is arranged between the support leg and the bottom surface, and when the mounting bracket has a U-shaped cross section, the edge of the longitudinal slot of the U-shaped mounting bracket is clamped in the groove.
According to the technical scheme, the sound insulation insert can be suitable for various mounting brackets. For example, when the mounting bracket is a C-shaped bracket, the sound damping insert of the present invention may be placed through the foot member into a longitudinal slot of the C-shaped bracket having a longitudinal extension along the entire length, and preferably the foot member further has a hook portion capable of hooking to a leg of the end of the side wall of the C-shape, so that the sound damping insert can be stably and firmly mounted to the side of the C-shaped bracket having the slot. When the mounting surface of the C-shaped bracket is not the side surface with the longitudinal slot, but the other side surface or the bottom surface, the sound insulation insert can be placed in the longitudinal opening on the side surface or the bottom surface of the mounting bracket through the elastic deformation of the ridge, at the moment, the cutting part accommodates the longitudinal edge of the mounting bracket bordering the longitudinal opening, and the shoulder part is meshed behind the longitudinal edge, so that the sound insulation insert can be mounted on any mounting surface of the mounting bracket, and has extremely wide application and adaptability.
In addition, when the mounting bracket is in other cross-sectional shapes, such as a closed rectangle, or L-shaped, or U-shaped, the sound insulation insert can be easily and reliably arranged on the mounting surface of the mounting bracket by inserting the sound insulation insert into the longitudinal openings through the ridge part as long as the mounting surface of the mounting bracket is provided with a plurality of longitudinal openings, thereby providing convenience for users and greatly reducing the construction cost.
The sound insulation insert is simple and small in structure, and through the accurate design structural characteristics, the part of the supporting surface formed by the ridge and the other part of the supporting surface formed by the side wings are supported between the load and the mounting surface of the mounting bracket together, so that the weight of the load component is well distributed. This reduces or eliminates inadvertent pulling of the sound damping insert from the mounting bracket if the load member (e.g., vent conduit) supported by the sound damping insert is laterally displaced. When the sound damping insert of the present invention is installed in a longitudinal opening of another type of bracket, the foot element will act as a supporting load member, the foot element generally having a higher elasticity and supporting height, thereby improving the decoupling of sound between the ventilation duct and the mounting bracket, achieving a more excellent sound damping effect.

Detailed Description
Next, a soundproof insert for a mounting bracket according to the present invention will be described with reference to fig. 1 to 6.
Fig. 1 shows a sound damping insert 100 for a mounting bracket of the present invention, typically positioned on the mounting bracket to reduce noise and/or vibration that may be generated by a load member (e.g., a ventilation duct) supported by the mounting bracket.
The mounting bracket is indicated by the numeral 2 at the beginning. The mounting bracket is typically a longitudinally extending strip of steel of a wide variety of types. According to their different transverse sectional shapes, they are classified into a C-type as shown in fig. 2, a U-type as shown in fig. 3 and 4, a rectangular-type as shown in fig. 5, an L-type as shown in fig. 6, and the like. It should be appreciated that the mounting bracket 200 of the present invention should not be limited to the exemplary embodiments described above, but rather has substantially longitudinally extending elongated sides to provide support or assembly regardless of the shape of the transverse cross-section of the mounting bracket. For example, a C-shaped mounting bracket as shown in FIG. 2, having a transverse cross-sectional shape similar to letter C, includes two opposing sides 201 and a bottom surface 202 perpendicular to the sides 201, opposite the bottom surface is a slot 203 extending entirely along its longitudinal length, i.e., the open portion of the C-shape, and an edge 204 bordering the slot 203 has an inwardly bent end 205. And, the side surface 201 and/or the bottom surface 202 are provided with at least one longitudinal opening 206, preferably, said longitudinal opening 206 is an oblong hole. The effect of the longitudinal opening 206 on the one hand reduces the overall weight of the bracket and on the other hand also provides the possibility and convenience for the combined mounting of the bracket. Depending on the space in which the mounting bracket is used and the mating parts, either surface of the mounting bracket, such as the face with the slot, the bottom, and the side, may be the mounting surface for supporting the load member. The foregoing is a brief description of the structure of a C-shaped mounting bracket, and as such, for mounting brackets having other transverse cross-sectional shapes, the mounting surface may be a side or bottom surface or a slotted surface, as will be described in further detail below with reference to the drawings and examples.
According to one embodiment of the invention, the acoustic barrier insert 100 is made of an elastomeric material. Elastomeric materials have proven to be particularly suitable as materials for acoustic insulation inserts. The sound insulation insert 100 may be selected from a suitable resilient material based on its particular sound absorbing and resilient properties. Preferably, the sound insulation insert 100 is made of rubber.
Referring to fig. 1, the sound dampening insert 100 includes a longitudinally extending base 101 and a foot member 109 extending downwardly from the base. Preferably, the sound insulation insert 100 extends longitudinally in the same transverse cross-sectional shape, and the length of the longitudinal extension thereof is adapted to the length of the longitudinal opening 206 formed in advance in the mounting surface of the mounting bracket, and preferably, the length of the longitudinal extension of the sound insulation 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 the bottom surface. When the foot member 109 of the sound damping insert is inserted into the interior of the mounting bracket, as shown in fig. 2 and 3, the bottom surface 102 abuts against the edge 204 of the longitudinal slot 203 of the C-shaped or U-shaped mounting bracket, and the support surface 103 supports the load components of the mounting bracket, such as the bottom surface of a ventilation duct (not shown), that is, the base 101 forms a space between the load components and the mounting surface of the mounting bracket, and since the sound damping insert 100 is made of an elastic material, vibration and/or noise that may be transmitted to the mounting bracket 200 by the load components such as the ventilation duct can be effectively reduced.
The base 101 includes a ridge 105 which is a generally centrally located, longitudinally extending oblong strip. The upper surface of the ridge 105 forms at least partially said support surface 103. Preferably, the support surface of the portion where the ridge is formed is provided with a region of reduced strength so that the ridge 105 is more easily elastically deformed to be inserted into the longitudinal opening 206 of the mounting bracket. More preferably, the area of reduced strength is such that a portion of the material is removed from the support surface of the ridge to form an arcuate concave surface 110, which ensures that the ridge 105 has sufficient strength to support the load, while also allowing elastic deformation of the ridge in a simple manner to facilitate placement of the ridge in the longitudinal opening 206.
The longitudinal sides of the ridge are provided with a cut-out 107 so as to form a shoulder 108 at the longitudinal side edges of the ridge. As shown in fig. 4 to 6, the ridge 105 is in its mounted state placed in the longitudinal opening 202 of the mounting bracket and the cutout 107 accommodates the longitudinal edge 207 of the mounting bracket bordering the longitudinal opening 206, the shoulder 108 engaging behind the longitudinal edge 207 of the mounting bracket bordering the longitudinal opening 206. In this way, by the cooperation of the shoulder 108 and the cutout 107, the sound insulation insert 100 is firmly attached to the mounting surface of the mounting bracket without being pulled out of the longitudinal opening 206 of the mounting bracket even when the load member is displaced laterally by vibration. The foot member 109 provides a strong support for the load member in the up-down direction, and the shoulder 108 and the shear 107 effectively relieve the lateral pressure generated by the shock of the load in the left-right direction. Preferably, the shoulder 108 has a sloping side 111 sloping downwardly relative to the support surface to facilitate insertion of the ridge 105 into the longitudinal opening 206 of the mounting bracket.
The base 101 further includes a side flap 104 extending laterally outwardly along the bottom surface. Preferably, the wings 104 comprise two wings extending laterally outwardly from the ridge 105, respectively, forming two wings symmetrically disposed along the ridge to ensure balance of the acoustic insulator insert during installation and use. The lower surface of the side flap 104 is coincident with the bottom surface of the base 101, i.e., the bottom surface of the side flap 104 is part of the bottom surface of the base. The upper surface of the flank 104 opposite the bottom surface extends laterally outwards from the lower end of the cutout 107, the upper surface of the flank extending progressively in an arc height until the upper surface of the flank coincides with the support surface 103, whereby the upper surface of the flank 103 constitutes another part of the support surface 103. In this way, when the sound damping 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 flanks 104 together can provide a firm support for the load member to more effectively provide decoupling of noise and damping of vibrations.
The side wings 104 also include chamfer faces 113 that slope downwardly relative to the support surface. The chamfer 113 is located at the lateral edge of the wing, which slopes downwardly from the outer side of the support surface 103 of the other part formed by the wing. The chamfer 113 can reduce the overall material consumption of the sound insulation insert, is beneficial to controlling the cost, and makes the sound insulation insert molding process simpler and more convenient. More preferably, the side flaps include a flange 114 that projects downwardly relative to the bottom surface. The flange 114 is located at the laterally outermost side of the bottom surface and is snap-engageable with the upper end of the side 201 of the mounting bracket to provide a more secure mounting and securing between the sound damping insert and the mounting bracket. While when the mounting surface of the mounting bracket is its narrower side 201, for example, as shown in fig. 5 and 6, the region between the side wings and the ridge, i.e., the portion of the side wing upper surface that increases from the shear curve, may also function as a clamping bracket mounting surface.
Preferably, the side flaps 104 are provided with through holes 112 or openings, or other forms of strength reducing areas, for reducing the strength of the elastic material. Preferably, the through hole 112 is disposed below the supporting surface of the other portion formed on the upper surface of the side wing, because this portion is the portion of the side wing with the highest height, that is, the portion with the thickest elastic material, so that the portion of the elastic material is removed to form the longitudinally extending through hole, so that the side wing can be properly deformed when being subjected to pressure, particularly when being subjected to shear force, and the through hole 112 formed in the side wing can effectively counteract vibration or displacement caused by the shear force.
According to a preferred embodiment of the invention, the foot element 109 comprises two opposing downwardly extending legs 115, which when the mounting bracket is of a C-or U-shaped cross-sectional shape have a slot 203 extending along the entire bracket length, the legs 115 being placed in the slot 203 in the mounted state. Preferably, the legs 115 have hooks 116 at their ends opposite to the bottom surface, and when the mounting bracket has a C-shaped cross-sectional shape, the hooks 116 are hooked on the two ends 205 of the C-shape of the mounting bracket, respectively, so that the sound insulation insert 100 is more reliably and stably fixed in the slot of the C-shape bracket.
More preferably, a lateral groove 117 is provided between the leg 109 and the bottom surface 102, and when the mounting bracket has a U-shaped cross-section, the end of the edge 204 that meets the slot 203 is engaged in the groove 117. In this way, it is advantageous to improve the stability and reliability of the installation of the sound insulation insert in the mounting bracket.
Preferably, the foot member 109 and the base 101 are integrally formed. Alternatively, the base and foot members of the present invention may be composed of elastomeric materials having different properties. For example, a material may be selected for the base that is slightly harder than the foot element.
As described above, the soundproof insert of the present invention can be adapted to various types of mounting brackets and any mounting surfaces of the mounting brackets. For example, when the mounting bracket is a C-shaped or U-shaped bracket, as shown in FIGS. 2 and 3, the sound insulation insert 100 of the present invention may be positioned within the slot 203 of the C-shaped or U-shaped bracket by the foot member 109. When the mounting surface of the mounting bracket is not the side having the slot 203, for example, as shown in fig. 4 to 6, the sound insulation insert 100 of the present invention can be placed in the longitudinal opening 206 of the mounting surface by elastic deformation of the ridge 105 when the mounting surface is the bottom surface or the side of the mounting bracket. Therefore, the sound insulation insert has extremely wide application occasions and suitability, provides convenience for users, and greatly reduces construction cost.
The sound insulation plug-in is simple in structure and small and exquisite. In particular, when the sound insulation insert of the present invention is mounted in the longitudinal opening 206 of the mounting bracket by the ridge 105, the support surface 103 defined by the ridge 105 and the side wings 104 are together strongly supported between the load and the mounting surface of the mounting bracket, the weight of the load component is well distributed, and the cutout 107 and the shoulder 108 sandwich the longitudinal edge of the mounting bracket bordering the longitudinal opening, reducing or eliminating the risk of the sound insulation insert being pulled from the mounting surface of the mounting bracket unintentionally. The foot element 109 will act as a support, the foot element 109 generally having a higher support height and better resilience, thereby improving the decoupling of sound between the load components such as ventilation ducts and the mounting bracket with a better sound insulation effect.
As previously mentioned, although in the description exemplary embodiments of the invention have been described with reference to the accompanying drawings, the invention is not limited to the above-described specific embodiments, but many other embodiments are possible, the scope of which should be defined by the claims and their equivalents.
