Description

Technical Field

[0001] This invention relates to the field of building envelope and building vibration and noise reduction technology, and in particular to a vibration-damping base and a noise-reducing curtain wall. Background Technology

[0002] In modern architectural design, curtain walls, as the building envelope, must not only meet the core requirements of lighting, energy conservation, and architectural aesthetics, but also address the increasingly prominent broadband noise pollution problem in the urban environment.

[0003] Current noise reduction technologies for building curtain walls mostly focus on optimizing the panels themselves. The core idea is based on the mass law and the principle of multi-layer sound insulation: by increasing the thickness of the glass, setting up hollow interlayers, and using laminated glass, the sound energy is attenuated by utilizing the difference in acoustic impedance of different media, with a focus on blocking mid-to-high frequency airborne sound.

[0004] However, this type of technology has significant limitations: on the one hand, in order to improve the low-frequency noise reduction effect, the panel density needs to be increased significantly or multiple layers of structure need to be added, which leads to an increase in the overall weight of the curtain wall. This not only increases the material and construction costs, but also puts higher demands on the load-bearing capacity of the main building structure, which runs counter to the development trend of green building lightweighting and low carbonization; on the other hand, this type of technology completely ignores the key influence of the curtain wall support as a connecting hub, making it a weak link in the noise reduction system.

[0005] As the connecting carrier between the curtain wall panels and the main building structure, the curtain wall support is traditionally designed using rigid materials such as steel keel and aluminum alloy profiles, which are directly welded or bolted together to form a rigid force transmission path. This rigid connection method is prone to causing sound bridging effect. External vibration energy can be quickly transmitted to the curtain wall panel through the support, making the panel a secondary source of radiated sound. This causes the noise reduction design of the panel itself to fail. Even if high-performance double-glazed glass is used, vibration can still bypass the sound insulation structure of the glass through the rigid support, efficiently transmitting low-frequency noise into the room.

[0006] To alleviate the sound bridge problem, some existing technologies attempt to add elastic gaskets, such as rubber pads, at the connection between the support and the panel or the main building structure. However, such solutions have obvious drawbacks: First, the damping performance of the vibration reduction material is insufficient, and it can only slightly reduce vibration in a specific frequency band, which cannot cover the vibration transmission requirements of broadband noise. Second, the elastic gasket has poor integration with the support and panel, and is prone to aging and deformation after long-term use, which leads to a rapid decline in the vibration reduction effect and affects the stability of the curtain wall structure.

[0007] To address this, a vibration-damping base and a noise-reducing curtain wall are proposed. Summary of the Invention

[0008] Therefore, the technical problem to be solved by the present invention is: how to improve the vibration reduction and noise reduction effect of curtain walls with the same or less thickness and weight.

[0009] The above-mentioned technical problems are solved by the following technical solution: The present invention proposes a vibration damping base, including a first connecting member and a second connecting member rotatably connected to the first connecting member, wherein a third connecting member is rotatably provided on the second connecting member; It also includes a support mechanism that is rotatably mounted on the second connecting member; The first connector is provided with a first slide rail, and the first slide rail is provided with a first blocking part; The third connector is provided with a second slide rail, and the second slide rail is provided with a second blocking part; The two ends of the support mechanism are respectively slidably disposed in the first slide rail and the second slide rail; When the two ends of the support mechanism abut against the first blocking part and the second blocking part respectively, the support mechanism is supported between the first connecting member and the third connecting member, and the tilt angle of the support mechanism is not 180 degrees.

[0010] In a preferred embodiment of the vibration damping base of the present invention: the first connecting member is provided with an upper connecting sleeve; The second connector is provided with an upper bushing and a lower bushing; The third connector is provided with a lower connecting sleeve; The upper connecting sleeve and the upper shaft sleeve are provided with a first connecting shaft; The lower connecting sleeve and the lower shaft sleeve are provided with a second connecting shaft.

[0011] In a preferred embodiment of the vibration damping base of the present invention: a third elastic damping element is provided outside the first connecting shaft; The second connecting shaft is provided with a fourth elastic damping element on its exterior; The third elastic damping element is disposed between the upper connecting sleeve and the upper shaft sleeve; The fourth elastic damping element is disposed between the lower connecting sleeve and the lower shaft sleeve.

[0012] In a preferred embodiment of the vibration damping base of the present invention: both the first connector and the third connector are L-shaped structures, and the first connector and the third connector are rotationally symmetrical.

[0013] In a preferred embodiment of the vibration damping base of the present invention: the support mechanism includes a support barrel and a first elastic damping member disposed in the support barrel, both ends of the support barrel are slidably provided with support bodies, and the first elastic damping member is located between the two support bodies.

[0014] In a preferred embodiment of the vibration damping base of the present invention: a limiting ring is provided on the second connecting member, and a rubber sleeve is provided inside the limiting ring; The outer wall of the support barrel is provided with a rotating ball; The rotating ball is rotatably disposed within the rubber sleeve.

[0015] In a preferred embodiment of the vibration damping base of the present invention, the support mechanism further includes a second elastic damping element sleeved on the outside of the support body.

[0016] In a preferred embodiment of the vibration damping base of the present invention: one end of the support body is provided with an abutting part, and one end of the support body is provided with a squeezing part; The extrusion section and the first elastic damping element are in contact.

[0017] The present invention also proposes a noise-reducing curtain wall, including the aforementioned vibration-damping base and the curtain wall body; The curtain wall body is installed on the base through several of the aforementioned vibration damping bases.

[0018] In a preferred embodiment of the noise-reducing curtain wall of the present invention: the top of the curtain wall body is provided with a protrusion, and the bottom of the curtain wall body is provided with a snap-fit ​​part; The snap-fit ​​part is provided with a buffer part; The curtain wall body is equipped with a sealing strip on its side.

[0019] The beneficial effects of this invention are as follows: when the curtain wall body is subjected to vibration or sound energy during use, the slight deflection of the second connector allows the curtain wall body to move slightly to dissipate energy. This flexible connection method not only ensures the connection strength and stability of the curtain wall, but also has a certain buffering capacity, which can avoid the sound bridge effect caused by traditional rigid connections. It allows external vibration energy to be quickly dissipated through the vibration damping base, preventing the curtain wall panel from becoming a secondary source of radiated sound. This allows the curtain wall body with the same mass and thickness to have a better vibration reduction and noise reduction effect, significantly reducing the cost of curtain wall manufacturing under the same noise reduction conditions, and improving the vibration reduction and noise reduction effect of curtain walls with the same or less thickness and weight.

[0030] To enable those skilled in the art to better understand the present invention, the present invention will be further described in detail below with reference to specific embodiments and accompanying drawings.

[0031] The terminology used in this invention is that which is currently widely used in the art in consideration of the function of the invention; however, these terms may vary according to the intent of those skilled in the art, precedent, or new technology in the art. Furthermore, specific terms may be chosen by the applicant, and in such cases, their detailed meanings will be described in the detailed description of the invention. Therefore, the terms used in this specification should not be construed as simple names, but rather based on their meanings and the overall description of the invention.

[0032] Reference Figures 1-8This embodiment provides a vibration damping base, including a first connector 1 and a second connector 2 rotatably connected to the first connector 1. A third connector 3 is rotatably provided on the second connector 2. The first connector 1, the second connector 2, and the third connector 3 are rotatably connected in sequence. The first connector 1 is used to connect the curtain wall body 7, and the third connector 3 is used to connect the base. The base includes a wall surface, an aluminum alloy profile, and a steel keel.

[0033] It also includes a support mechanism 4 rotatably mounted on the second connector 2; the support mechanism 4 is used to separate the first connector 1 and the third connector 3 and support them together; the support mechanism 4 can rotate on the second connector 2 to change its angle.

[0034] The first connector 1 is provided with a first slide rail 11, and the first slide rail 11 is provided with a first blocking part 111; The third connector 3 is provided with a second slide rail 31, and the second slide rail 31 is provided with a second blocking part 311; The two ends of the support mechanism 4 are slidably disposed in the first slide rail 11 and the second slide rail 31 respectively; the first slide rail 11 and the second slide rail 31 are used to guide the movement direction of the two ends of the support mechanism 4, and the first blocking part 111 and the second blocking part 311 are used to support and limit the two ends of the support mechanism 4, and limit the deflection angle of the support mechanism 4.

[0035] When the two ends of the support mechanism 4 abut against the first blocking part 111 and the second blocking part 311 respectively, the support mechanism 4 is supported between the first connecting member 1 and the third connecting member 3, and the tilt angle of the support mechanism 4 is not 180 degrees.

[0036] When the vibration damping base Q is installed in place, under the gravity of the curtain wall body 7, the first connector 1 and the third connector 3 will generate relative displacement, driving the support mechanism 4 to slide in the first slide rail 11 and the second slide rail 31 until it abuts against the first blocking part 111 and the second blocking part 311. At this time, the angle between the support mechanism 4 and the horizontal direction is maintained at a state other than 180 degrees, thus forming a stable support structure with micro-motion energy dissipation space. This design is to avoid the "dead point" of the movement of the support mechanism 4, ensuring that it has a clear support force, and reserving space for the support mechanism 4 to rotate or compress relative to the second connector 2 when subjected to vibration impact, thereby using elastic damping elements to dissipate energy.

[0037] Reference Figure 8As shown, the curtain wall body 7 is installed on the first connector 1, and the third connector 3 is installed on the base. It should be noted that both the first connector 1 and the third connector 3 have multiple mounting holes for fixing them with bolts. The first connector 1 is installed at the frame of the curtain wall body 7. Each frame of the curtain wall body 7 has at least four vibration damping bases Q to achieve better support. In addition, the vibration damping bases Q can be glued to the middle area of ​​the curtain wall body 7 to support the middle of the curtain wall body 7 and improve the stability of the curtain wall body 7. The glue also helps to maintain the integrity of the curtain wall body 7 and avoid sound leakage caused by perforation. The multiple vibration damping bases Q are connected to the curtain wall body 7 by the first connector 1 and connected to the base by the third connector 3, so that the plane of the first connector 1 and the plane of the third connector 3 always remain parallel. Therefore, the curtain wall body 7 connected by the vibration damping bases Q will move parallel to the surface of the base when it moves.

[0038] During installation, the vibration damping base Q requires the second connector 2 to form an acute angle with the base in the direction of gravity. Therefore, under the weight G of the curtain wall body 7, the second connector 2 will have a counter-clockwise rotational tendency. The two ends of the support mechanism 4 are slid into the first slide rail 11 and the second slide rail 31 respectively, and the tilt angle of the support mechanism 4 is adjusted until it contacts the first blocking part 111 and the second blocking part 311 respectively. (Refer to...) Figure 8 In the schematic diagram on the right, the left end of the support mechanism 4 is lower than the right end. Under the action of the gravity G of the curtain wall body 7, it will be converted into a pressure N applied to the first connector 1, so that the first connector 1 has a tendency to move closer to the third connector 3. The pressure N can keep the support mechanism 4 tilted in this state to form support and fixation for the curtain wall body 7. The position of the curtain wall body 7 can be fixed by using the gravity G of the curtain wall body 7.

[0039] Reference Figure 8 When the curtain wall needs maintenance or replacement, simply lift the curtain wall body 7 or rotate the support mechanism 4 to disengage both ends of the support mechanism 4 from the first slide rail 11 and the second slide rail 31. Since the installation position of the third connector 3 is fixed, after lifting the curtain wall body 7, the second connector 2 will deflect. (Refer to...) Figure 8 The leftmost diagram shows that the curtain wall body 7 will be far away from the base and will rise to a certain extent. Maintenance personnel can use this space to disassemble and install the bolts on the first connector 1 and the third connector 3, providing more maintenance and operation space and reducing the difficulty of maintenance.

[0040] Reference Figure 8The rightmost schematic diagram shows that when the curtain wall body 7 is subjected to vibration or sound energy during normal use, it can dissipate energy through the slight deflection of the second connector 2 and the slight movement of the curtain wall body 7. This flexible connection method not only ensures the connection strength and stability of the curtain wall, but also has a certain buffering capacity. The gravity G, together with the first blocking part 111 and the second blocking part 311, forms an effective limit on the support mechanism 4, so that the curtain wall can maintain a relatively stable state. When subjected to vibration, the tilting of the second connector 2 and the translation of the first connector 1 are used to dissipate energy and buffer it. This can avoid the sound bridge effect caused by traditional rigid connections, so that the external vibration energy can be quickly dissipated through the vibration damping base Q, and the curtain wall panel can be prevented from becoming a secondary source of radiated sound. With this vibration damping base Q, the curtain wall body 7 with the same mass and thickness can have a better vibration damping and noise reduction effect, which significantly reduces the cost of curtain wall manufacturing under the same noise reduction conditions, and improves the vibration damping and noise reduction effect of curtain walls with the same or less thickness and weight.

[0041] Reference Figures 1-8 As an optional embodiment: the first connector 1 is provided with an upper connecting sleeve 12; the first connector 1 and the upper connecting sleeve 12 are integrated into one structure, and both the first connector 1 and the upper connecting sleeve 12 are made of metal.

[0042] The second connector 2 is provided with an upper bushing 23 and a lower bushing 24; the second connector 2, the upper bushing 23 and the lower bushing 24 are integrated into a single structure and are all made of metal. The upper bushing 23 and the lower bushing 24 are respectively located at both ends of the second connector 2.

[0043] The third connector 3 is provided with a lower connecting sleeve 32; the third connector 3 and the lower connecting sleeve 32 are integrated into one structure and are both made of metal.

[0044] The upper connecting sleeve 12 and the upper shaft sleeve 23 are provided with a first connecting shaft 5; the first connecting shaft 5 is used to realize the connection between the upper connecting sleeve 12 and the upper shaft sleeve 23 so that the first connecting member 1 and the second connecting member 2 can rotate.

[0045] The lower connecting sleeve 32 and the lower shaft sleeve 24 are provided with a second connecting shaft 6. The second connecting shaft 6 is used to connect the lower connecting sleeve 32 and the lower shaft sleeve 24 so that the second connecting member 2 and the third connecting member 3 can rotate.

[0046] Both the first connecting shaft 5 and the second connecting shaft 6 are made of metal.

[0047] Preferably, a third elastic damping element 51 is provided on the outside of the first connecting shaft 5; The third elastic damping element 51 is located between the upper connecting sleeve 12 and the upper shaft sleeve 23. Multiple third elastic damping elements 51 are provided and are evenly distributed on the outside of the first connecting shaft 5.

[0048] The second connecting shaft 6 is provided with a fourth elastic damping element 61 on its exterior. The fourth elastic damping element 61 is located between the lower connecting sleeve 32 and the lower bushing 24.

[0049] Multiple fourth elastic damping elements 61 are provided and are evenly distributed on the outside of the second connecting shaft 6.

[0050] Preferably, the third elastic damping element 51 and the fourth elastic damping element 61 can be materials or components with elastic damping characteristics such as rubber, silicone, polyurethane, helical spring, disc spring or gas spring.

[0051] Due to the installation of the third elastic damping element 51 and the fourth elastic damping element 61, when the curtain wall body 7 is subjected to horizontal vibration, the mutual misalignment of the first connector 1, the second connector 2, and the third connector 3 can compress the third elastic damping element 51 and the fourth elastic damping element 61, and dissipate energy through the deformation of the third elastic damping element 51 and the fourth elastic damping element 61. When the displacement of the first connector 1, the second connector 2, and the third connector 3 causes misalignment, the first slide rail 11 and the second slide rail 31 will also be misaligned. At this time, the support mechanism 4 rotates on the second connector 2 and maintains contact between the two ends of the support mechanism 4 and the first blocking part 111 on the first slide rail 11 and the second blocking part 311 on the second slide rail 31, thereby achieving the buffering of horizontal vibration. By utilizing the rotational connection between the first connector 1, the second connector 2, and the third connector 3, the vibration damping base Q can achieve vertical vibration buffering. The combination of the two can achieve three-dimensional vibration damping, which can reduce the transmission of vibration from any direction and further improve the vibration reduction and noise reduction effect.

[0052] Preferably, both the first connector 1 and the third connector 3 are L-shaped structures, and the first connector 1 and the third connector 3 are arranged in a rotationally symmetrical manner.

[0053] The L-shaped structure allows for an increase in the settable length of the support mechanism 4, and enables the curtain wall body 7 to be positioned away from the base. It also increases the distance between the first connector 1, the second connector 2, and the third connector 3, making it easier for installers to install the bolts on the first connector 1 and the third connector 3.

[0054] Reference Figures 1-8 As an optional embodiment: the support mechanism 4 includes a support barrel 41 and a first elastic damping member 42 disposed in the support barrel 41. Both ends of the support barrel 41 are slidably provided with support bodies 43, and the first elastic damping member 42 is located between the two support bodies 43.

[0055] The support barrel 41 is made of metal and is hollow inside. The first elastic damping element 42 can be rubber or a spring, preferably rubber. The support body 43 is made of metal. Each vibration damping base Q has two symmetrically arranged support bodies 43 in the support barrel 41. The ends of the two support bodies 43 are connected to the first slide rail 11 and the second slide rail 31 respectively. The support bodies 43 can slide inside the support barrel 41.

[0056] When in use, the vibration energy can be dissipated by the mutual compression of the first elastic damping element 42 by the two supports 43, thereby further improving the vibration reduction effect.

[0057] It should be noted that the first connecting piece 1, the second connecting piece 2, and the third connecting piece 3, which are rotated in sequence, can achieve buffering in the vertical direction. The third elastic damping piece 51 and the fourth elastic damping piece 61 can achieve buffering in the horizontal direction, while the first elastic damping piece 42 can achieve buffering in the direction perpendicular to the curtain wall body 7. This enables the vibration damping base Q to achieve three-dimensional buffering and energy dissipation, thereby improving its vibration reduction and noise reduction effect.

[0058] Reference Figures 1-8 As an optional embodiment: the second connector 2 is provided with a limiting ring 21, and the limiting ring 21 is provided with a rubber sleeve 22; wherein, the limiting ring 21 is made of metal.

[0059] The outer wall of the support barrel 41 is provided with a rotating ball 45; the rotating ball 45 is made of metal and is rotatably located inside the rubber sleeve 22. The rubber sleeve 22 can increase the friction. The slight rotation of the rotating ball 45 can dissipate energy and optimize the vibration reduction effect.

[0060] Preferably, the support mechanism 4 further includes a second elastic damping element 44 sleeved on the outside of the support body 43, wherein the second elastic damping element 44 is a spring.

[0061] It should be noted that one end of the support body 43 is provided with an abutting part 431, and one end of the support body 43 is provided with a squeezing part 432; the end of the second elastic damping member 44 is in contact with the squeezing part 432, the abutting part 431 is spherical; the squeezing part 432 and the first elastic damping member 42 are in contact.

[0062] Reference Figures 1-8 This embodiment proposes a noise reduction curtain wall, including a vibration damping base Q and a curtain wall body 7; the curtain wall body 7 is installed on the base through a plurality of vibration damping bases.

[0063] Among them, the curtain wall body 7 can be a hollow laminated glass curtain wall, a vacuum glass curtain wall, an aluminum honeycomb composite panel curtain wall, etc., and in particular, a high-performance sound insulation curtain wall is used to improve the overall noise reduction effect of the curtain wall structure.

[0064] By setting the vibration damping base Q, the vibration damping effect of the curtain wall body 7 can be improved, and the transmission of vibration can be reduced.

[0065] Preferably, the top of the curtain wall body 7 is provided with a protrusion 71, and the bottom of the curtain wall body 7 is provided with a snap-fit ​​part 72; a buffer part 721 is provided inside the snap-fit ​​part 72. A sealing strip 73 is provided on the side of the curtain wall body 7.

[0066] Among them, the protrusion 71 and the snap-fit ​​part 72 are made of hard rubber. The middle part of the snap-fit ​​part 72 is concave, and its concave state matches the protrusion of the protrusion 71. The buffer part 721 is a sealing element made of flexible rubber, and the sealing strip 73 is made of rubber.

[0067] It should be noted that the protrusion 71, the snap-fit ​​part 72, and the sealing strip 73 are all glued to the curtain wall body 7, and the buffer part 721 is glued inside the snap-fit ​​part 72.

[0068] In use, the protrusions 71, snap-fit ​​parts 72, and sealing strips 73 are adhered to the perimeter of the curtain wall body 7 using structural adhesive. Then, the buffer part 721 is glued into the snap-fit ​​part 72. The first connector 1 is installed on the frame of the curtain wall body 7 using bolts, and the third connector 3 is installed on the base using bolts. The arrangement of the curtain wall body 7 is as follows: Figure 1 After all the curtain wall installations are completed, refer to Figure 8 The rightmost schematic diagram shows that the protrusions 71 and snap-fit ​​parts 72 of two adjacent curtain wall panels are interlocked, and the sides of the curtain wall body 7 are bonded together by sealing strips 73 to form a continuous and sealed wall. The protrusions 71, snap-fit ​​parts 72, and sealing strips 73 around the curtain wall body 7 can play a certain buffering role, avoid the occurrence of sound bridge phenomenon, and allow the curtain wall body 7 to have a certain amount of movement space. When subjected to vibration, the curtain wall body 7 can dissipate energy through movement. Furthermore, the protrusions 71, snap-fit ​​parts 72, and sealing strips 73 made of rubber can maintain the sealing between the curtain wall bodies 7, and the interlocking of the protrusions 71 and snap-fit ​​parts 72 can improve the stability between the curtain wall bodies 7.

[0069] When dismantling or replacing the curtain wall body 7 at the corresponding location, the protrusions 71, snap-fit ​​parts 72, and sealing strips 73 around the corresponding curtain wall body 7 can be torn off or cut off. Then, the surface of the curtain wall body 7 to be replaced is held by a suction cup hoisting device, and the corresponding curtain wall body 7 is pulled up. During the pulling process, as the curtain wall body 7 rises and moves away from the base, the adjacent curtain wall bodies 7 will move away from each other, which increases the space for installation and dismantling, making it easier for operators to dismantle the curtain wall body 7. After replacing the new curtain wall body 7, the angle of the support body 43 is adjusted while lowering the curtain wall body 7 so that it can abut against the first blocking part 111 and the second blocking part 311 to form support for the curtain wall body 7.

[0070] Finally, it should be noted that the methods and devices described in detail above are merely embodiments, and those skilled in the art can modify these embodiments in different ways as long as they do not depart from the scope of the present invention.
