Abstract
Description
Technical Field
[0001] The present invention relates to a curtain wall keel system and a construction method thereof, and in particular to a keel structure system of a spatial hyperbolic special-shaped curtain wall and a construction method thereof. Background Art
[0002] In recent years, hyperbolic curtain walls have become increasingly popular in architectural structures. Not only do they accommodate a wide range of architectural designs, their non-smooth surface also diffusely reflects outdoor solar radiation, mitigating the urban heat island effect. Furthermore, their complex curved structure offers a larger surface area than traditional flat curtain walls, providing better sound absorption and minimal echo, making them suitable for use in structures such as studios, conference rooms, and recording studios.
[0003] The Chinese invention patent with publication number CN112196165B discloses a spatial hyperbolic special-shaped curtain wall keel structure system and its construction method, including a rectangular sub-frame and a single curtain wall panel embedded in the rectangular sub-frame. The keel structure system includes a steel square tube directly connected to the main steel structure, a secondary keel and a connecting drum for connecting the steel square tube and the secondary keel. The connecting drum includes a central tubular structure, connecting ear plates distributed in a radial shape on the outer wall of the central tubular structure, and a first connecting plate provided on the end face of the central tubular structure facing the main steel structure. Both ends of the secondary keel are provided with attachment ear plates for bolting to the connecting ear plates. The ends of the secondary keel close to the connecting drums on both sides are also provided with adapter components for connecting and fixing to the rectangular sub-frame.
[0004] The existing technology and the above-mentioned invention patents all have the following technical problems: Since the decibels of noise generated in some places such as studios, conference rooms, and recording studios can reach 100 decibels or even higher, and the human body is in an environment exceeding 60 decibels for a period of time, it may cause certain damage to hearing and other aspects. In the existing technology, when a keel system is used to install curtain walls for sound insulation, the curtain wall absorbs the noise and transmits the sound wave vibration to the keel structure system, causing the keel to vibrate and causing the rigid connection between the keel and the curtain wall to loosen, affecting the structural strength and service life of the curtain wall and the keel structure system. In addition, in the keel structure system of the existing technology, the keel needs to be customized according to the structure of the hyperbolic special-shaped curtain wall, and has poor adaptability. In the actual construction process, the curvature of the keel may need to be adjusted according to the construction situation, resulting in certain limitations in the use of customized keels and increasing the difficulty of installing the keel structure system.
[0005] Therefore, it is necessary to provide a keel structure system and a construction method for a spatial hyperbolic special-shaped curtain wall, which can be used to eliminate the influence of noise and vibration on the keel structure system and adjust the keel curvature.

[0026] Compared with the prior art, the present invention has the following beneficial effects:
[0027] 1. According to the present invention, due to the first frame, the second frame, the connecting mechanism and the steering mechanism, two adjacent second frames and the first frame and the second frame can be relatively plugged in through the rotating connecting frame of the connecting mechanism. The two rotating connecting frames are rotatably connected through the steering mechanism, and the curvature of the entire adjustable special-shaped keel at different positions can be adjusted. In addition, the setting directions of the two rotating connecting frames are perpendicular, and the rotation adjustment range is large, which meets the design requirements of the spatial hyperbolic special-shaped curtain wall for the curvature of the keel.

The vibration-damping plate translates along the axial direction of the sliding sleeve under the acoustic vibration, and the vibration-damping plate drives the sliding sleeve and the spiral fixing cap to rotate relative to the curtain wall and the second frame, and is reset under the drive of the vibration-damping spring, thereby achieving absorption of the acoustic vibration, avoiding the influence of the acoustic vibration on the connection nodes on the adjustable special-shaped keel and the connection node between the adjustable special-shaped keel and the curtain wall, and preventing the keel structure system from loosening.
[0029] 3. Since the present invention is provided with a cleaning rod, when the sliding sleeve rotates, the outer wall of the sliding sleeve and the cleaning rod slide relative to each other, so that the cleaning rod cleans the sliding sleeve, avoids dust accumulation on the fixing mechanism, and reduces the cost of subsequent manual maintenance.

DETAILED DESCRIPTION
[0039] The present invention will be further described below with reference to the accompanying drawings and specific embodiments.
[0040] Please see the attached Figure 1 and attached Figure 2 A keel structure system for a spatial hyperbolic special-shaped curtain wall includes a fixing seat 1, a first frame 2, a second frame 3, a connecting mechanism 4, a steering mechanism 5 and a fixing mechanism 6; connecting mechanisms 4 are coaxially installed at both ends of the second frame 3, and the connecting mechanisms 4 at the ends of two adjacent second frames 3 are arranged opposite to each other and are rotatably connected through a steering mechanism 5, so that several second frames 3 are sequentially connected through the connecting mechanism 4 and the steering mechanism 5 to form an adjustable special-shaped keel; a connecting mechanism 4 is coaxially installed at one end of the first frame 2, and the connecting mechanisms 4 on a pair of first frames 2 are respectively arranged opposite to the connecting mechanisms 4 at both ends of the adjustable special-shaped keel and are rotatably connected through a steering mechanism 5, and the other ends of the pair of first frames 2 are respectively fixedly installed on the building structure through the fixing seat 1; one end of the fixing mechanism 6 is vertically connected to the second frame 3, and the other end of the fixing mechanism 6 is vertically connected to the inner wall of the curtain wall.
[0041] Two opposing connecting mechanisms 4 can be rotatably connected via a steering mechanism 5 to meet the connection and relative rotation requirements of two adjacent second frames 3. The number, specifications, and length of the second frames 3 can be adjusted according to actual needs to meet the design requirements for the load-bearing capacity, length, and curvature of the keel. The adjustable, shaped keel is fixed to the building structure at both ends via the first frame 2 via a fixing base 1. Two adjacent adjustable shaped keels can also be fixedly connected via the fixing base 1 to extend the keel length, meeting the installation requirements of long-span, hyperbolic, shaped curtain walls. Multiple adjustable shaped keels are arranged according to the curtain wall design to form a keel structure system. The curtain wall is mounted on the second frames 3 via fixing mechanisms 6. The number of fixing mechanisms 6 can be adjusted according to the size and weight of the curtain wall to ensure that four sets of fixing mechanisms 6 are securely connected between the four second frames 3 at the four corners of the curtain wall. The number of fixing mechanisms 6 attached to each curtain wall can also be increased. The fixing mechanisms 6 secure the curtain wall while also absorbing acoustic vibrations transmitted by the curtain wall, ensuring the structural stability of the entire keel structure.
[0042] Preferably, the first frame 2 and the second frame 3 can both be made of square steel pipes.
[0043] Please see the attached Figure 3 and attached Figure 4 The connecting mechanism 4 includes a rotating connecting frame 41 and a connecting sleeve 42; the rotating connecting frame 41 is a U-shaped structure with one end open, and the open ends of the rotating connecting frames 41 of the two connecting mechanisms 4 arranged opposite to each other are vertically plugged in, that is, the planes where the two rotating connecting frames 41 are located are perpendicular to each other, and the steering mechanism 5 is rotatably connected to the open ends of the two rotating connecting frames 41; one end of the connecting sleeve 42 is fixedly set on the closed end of the rotating connecting frame 41, and the other end of the connecting sleeve 42 is detachably sleeved on the end of the first frame 2 or the end of the second frame 3.
[0044] The open end of each rotating connector 41 is connected to the steering mechanism 5, allowing each rotating connector 41 to rotate relative to the adjacent rotating connector 41 about the open end as the axis, thereby adjusting the angle between two adjacent second skeletons 3. Two adjacent U-shaped rotating connectors 41 are vertically connected to each other, allowing for rotational adjustment in different directions. This expands the angle adjustment range between two adjacent second skeletons 3 and meets the requirements for varying the curvature of the keel in different directions.
[0045] A square through hole with the same size as the outer wall of the first frame 2 and the second frame 3 is formed in the middle of the connecting sleeve 42 for plugging the first frame 2 and the second frame 3 made of square steel pipes. No relative rotation will occur between the connecting sleeve 42 and the first frame 2 and the second frame 3.
[0046] Please see the attached Figure 3 and attached Figure 4The steering mechanism 5 includes a stud bolt 51, a locking nut 52, a rotating seat 53, a thrust bearing 54 and a first limiting ring 55; the rotating seat 53 is arranged between the open ends of the two relatively inserted rotating connecting frames 41, and at least four mounting surfaces are formed on the rotating seat 53, and the four mounting surfaces are respectively arranged facing the open ends of the two rotating connecting frames 41; the thrust bearing 54 is arranged on the inner wall of the open end of the rotating connecting frame 41, and the first limiting ring 55 is located between the mounting surface of the rotating seat 53 and the thrust bearing 54. One end of the stud bolt 51 passes through the thrust bearing 54 and the first limiting ring 55 and is screwed to the mounting surface of the rotating seat 53. The other end of the stud bolt 51 passes through the open end of the rotating connecting frame 41 and is locked to the outside of the open end of the rotating connecting frame 41 through the locking nut 52.
[0047] Preferably, the rotating seat 53 can adopt a cubic structure with a side length less than the width of the opening of the rotating connecting frame 41. Two pairs of oppositely arranged surfaces are selected as four mounting surfaces on the rotating seat 53, and the center line of one pair of mounting surfaces is perpendicular to the center line of the other pair of mounting surfaces. The centers of the four mounting surfaces are all screwed to bolt columns 51, and threaded holes are reserved on the open ends of the rotating connecting frame 41. The open ends of the rotating connecting frame 41 are rotated around the bolt columns 51 relative to the rotating seat 53 by screwing, thereby achieving relative rotation between the two relatively plugged rotating connecting frames 41, and the rotation directions of the two rotating connecting frames 41 are perpendicular to each other. One end of the bolt column 51 is screwed into the rotating seat 53, and the thrust bearing 54 and the first limiting ring 55 can be tightened between the rotating seat 53 and the inner wall of the rotating connecting frame 41. The other end of the bolt column 51 can be locked to the outer wall of the rotating connecting frame 41 by the locking nut 52, locking the two rotating connecting frames 41 so that they cannot rotate relative to each other.
[0048] Please see the attached Figure 2 , Attachment Figure 5 To the attached Figure 7 The fixing mechanism 6 includes a first fixing component 61, a spiral fixing cap 62 and a second fixing component 63; one end of the first fixing component 61 is fixedly connected to the side wall of the second frame 3, and the other end of the first fixing component 61 is coaxially inserted into the second fixing component 63; one end of the spiral fixing cap 62 is rotatably sleeved on the first fixing component 61, and the other end of the spiral fixing cap 62 is coaxially connected to one end of the second fixing component 63; the other end of the second fixing component 63 is fixedly connected to the inner wall of the curtain wall.
[0049] The first fixing component 61 is used for fixing the connection between the fixing mechanism 6 and the second frame 3, the second fixing component 63 is used for fixing the connection between the fixing mechanism 6 and the curtain wall, and the spiral fixing cap 62 plays the role of a rotational connection between the first fixing component 61 and the second fixing component 63. The spiral fixing cap 62 cooperates with the second fixing component 63 to eliminate the influence of noise and vibration on the keel.
[0050] Please see the attached Figure 7 The first fixing component 61 includes a sliding sleeve rod 611 and a second limiting ring 612; one end of the sliding sleeve rod 611 is vertically connected to the side wall of the second frame 3, and the other end of the sliding sleeve rod 611 is coaxially inserted into the second fixing component 63; the second limiting ring 612 is coaxially arranged on one end of the sliding sleeve rod 611, and one end of the spiral fixing cap 62 is rotatably sleeved on the sliding sleeve rod 611 through the second limiting ring 612.
[0051] The sliding rod 611 can be made of a round steel tube and secured to the sidewall of the second frame 3 by welding, screwing, or other means. The outer diameter of the sliding rod 611 is smaller than the width of the sidewall of the second frame 3 to ensure reliable installation of the sliding rod 611. The second retaining ring 612 can be a circular ring structure that matches the dimensions of the sliding rod 611 and can be welded to the inner wall of the sliding rod 611. A groove that matches the outer ring of the second retaining ring 612 is reserved on the inner wall of the screw cap 62, thereby enabling the screw cap 62 to be rotatably engaged and limited on the sliding rod 611. The screw cap 62 can rotate relative to the sliding rod 611 via the second retaining ring 612.
[0052] Please see the attached Figure 7 The second fixing assembly 63 includes a sliding sleeve 631, a vibration damping plate 634, a vibration damping spring 635, a third fixing plate 636 and a cleaning assembly; the other end of the first fixing assembly 61 is coaxially inserted into one end of the sliding sleeve 631, and an outer thread joint 632 is formed on the outer wall of one end of the sliding sleeve 631, so that one end of the sliding sleeve 631 can be coaxially screwed to the other end of the spiral fixing cap 62 through the outer thread joint 632; the third fixing plate 636 is rotatably and coaxially clamped to the other end of the sliding sleeve 631, and the vibration damping plate 634 is connected to the third fixing plate 636 through the vibration damping spring 635. The vibration damping plate 634 is located in the sliding sleeve 631, and the vibration damping plate 634 is screwed to the inner wall of the sliding sleeve 631 through thread matching; the cleaning assembly is arranged on the inner wall of the third fixing plate 636 and is in relative sliding contact with the outer wall of the sliding sleeve 631. The outer wall of the third fixing plate 636 is fixedly connected to the inner wall of the curtain wall through an anti-slip pad.
[0053] The sliding sleeve 631 can be made of a round steel tube with an inner diameter slightly larger than the outer diameter of the sliding sleeve rod 611. The inner wall of the screw cap 62 is provided with internal threads for coaxial threaded engagement with the external thread connector 632 of the sliding sleeve 631, enabling synchronous rotation of the sliding sleeve 631 and the screw cap 62. The curtain wall absorbs acoustic vibrations and transmits them to the third fixing plate 636. Some of the noise propagates along the outer wall of the sliding sleeve 631, while the remaining vibrations propagate as acoustic waves within the internal cavity of the sliding sleeve 631, where they are absorbed by the damping plate 634 and damping spring 635.
[0054] The vibration damping plate 634, the vibration damping spring 635 and the sliding sleeve 631 form a Helmholtz resonator structure. The Helmholtz resonator structure consists of a short tube and a back cavity. Its working principle is: when the frequency of the sound wave acting on the outside is consistent with the natural frequency, the resonator will resonate, and the sound wave vibration in the resonator will be strongly amplified. Appropriately set acoustic resistance materials in the resonator can strongly consume sound energy, achieve good sound absorption effect, dissipate sound wave vibration, and thus avoid adverse effects on the reliability of the connection nodes of the keel structure system.
[0055] Under the influence of the acoustic wave vibration, the vibration damping plate 634 moves axially along the vibration damping spring 635. Since the third fixing plate 636 is fixedly connected to the curtain wall and remains stationary, under the guidance and restriction of the thread, the vibration damping plate 634 pushes the sliding sleeve 631 to rotate along the thread when it moves axially, thereby eliminating the radial force and axial force acting on the sliding sleeve 631 by the acoustic wave vibration, and ensuring the connection reliability between the first fixing component 61 and the second frame 3 and the second fixing component 63 and the curtain wall.
[0056] The pitch of the thread connecting the vibration damping plate 634 and the inner wall of the sliding sleeve 631 can be set longer based on the ambient noise level. Lubricant should be applied to the thread groove to reduce friction between the vibration damping plate 634 and the sliding sleeve 631. This ensures that the vibration damping plate 634 can move after vibration and push the sliding sleeve 631 to rotate along the thread. The vibration damping spring 635 is used to reset the vibration damping plate 634 and the sliding sleeve 631. The elastic coefficient of the vibration damping spring 635 can be adaptively selected based on the ambient noise level to ensure that the vibration damping plate 634 can move after absorbing the sound wave vibration and assist in resetting the vibration damping plate 634.
[0057] Preferably, an annular groove can be provided on the outer wall of the sliding sleeve 631 for embedding the inner ring of the third fixing plate 636, so that the sliding sleeve 631 can rotate relative to the third fixing plate 636 without sliding along the axial direction of the sliding sleeve 631, thereby not affecting the connection reliability between the second fixing assembly 63 and the curtain wall when the sliding sleeve 631 rotates.
[0058] Preferably, the anti-slip pad can be made of rubber to increase the friction between the third fixing plate 636 and the curtain wall, thereby ensuring the reliability of the connection between the third fixing plate 636 and the curtain wall. The third fixing plate 636 and the curtain wall can be fixed by bolts or other means. The length of the sliding sleeve 611 is preferably sufficient to fit the screw fixing cap 62 and the sliding sleeve 631 without colliding with the vibration damping plate 634.
[0059] Please see the attached Figure 5 To the attached Figure 8The cleaning assembly includes a cleaning rod 637 and a third limiting ring 638; the third limiting ring 638 is coaxially sleeved on the sliding sleeve 631, and the cleaning rod 637 is arranged between the third limiting ring 638 and the third fixed plate 636 along the axial direction of the sliding sleeve 631, and a plurality of cleaning rods 637 are arranged at intervals along the circumference of the sliding sleeve 631; a plurality of cleaning rods 637 are provided with tufts, and the tufts are attached to the outer wall of the sliding sleeve 631.
[0060] When sliding sleeve 631 rotates slightly, it rotates relative to third fixing plate 636, cleaning rod 637, and third retaining ring 638, causing the tufts on cleaning rod 637 to rub and clean the surface of sliding sleeve 631, preventing dust accumulation on the surface of sliding sleeve 631 and achieving a better cleaning effect. The number of cleaning rods 637 provided can be determined based on the amplitude of rotation caused by acoustic vibrations in the application scenario. Preferably, twelve cleaning rods 637 can be arranged at equal intervals outside sliding sleeve 631 to ensure that even a small rotation can produce an effective cleaning effect.
[0061] Please see the attached Figure 7 A first fixing plate 621 is formed at the other end of the spiral fixing cap 62; a second fixing plate 633 is formed on the sliding sleeve 631, and the second fixing plate 633 is located at one end of the external thread connector 632 away from the end of the sliding sleeve 631; when the external thread connector 632 is screwed and inserted into the spiral fixing cap 62, the first fixing plate 621 and the second fixing plate 633 are adhered and fixedly connected.
[0062] Bolt holes can be reserved on the first fixing plate 621 and the second fixing plate 633, and the first fixing plate 621 and the second fixing plate 633 can be fastened by bolts, so that the spiral fixing cap 62 and the sliding sleeve 631 can be reliably connected and rotate synchronously, and the vibration of the outer wall of the sliding sleeve 631 is absorbed by the second fixing plate 633 and the first fixing plate 621.
[0063] The first fixing plate 621 and the second fixing plate 633 are both provided with vibration-damping pads (not shown in the figure), so that when the first fixing plate 621 and the second fixing plate 633 are attached to each other, the two vibration-damping pads are attached to each other.
[0064] Preferably, the vibration-damping pad can be made of a sponge foam board to further absorb sound wave vibrations.
[0065] Please see the attached Figure 1 A fixing frame 11 is provided at the bottom of the fixing seat 1 , and the fixing frame 11 is fixed between the fixing seat 1 and the first frame 2 .
[0066] The fixing frame 11 can be used to bear the weight of the adjustable special-shaped keel. Preferably, the fixing frame 11 can adopt a triangular structure, which is used to fit the connection corner between the fixing seat 1 and the first frame 2, thereby improving the bearing capacity of the adjustable special-shaped keel and ensuring that the end of the adjustable special-shaped keel is reliably installed on the building structure through the fixing seat 1.
[0067] Please see the attached Figure 4 To the attached Figure 6 One end of the first skeleton 2 is formed with a plurality of first positioning screw holes 22, and a plurality of third positioning screw holes 44 are formed on the connecting sleeve 42, so that when the connecting sleeve 42 is sleeved on one end of the first skeleton 2, the plurality of first positioning screw holes 22 are respectively aligned with the plurality of third positioning screw holes 44, so that the first skeleton 2 is fixedly connected to the connecting sleeve 42 through the first positioning screw holes 22 and the third positioning screw holes 44 by the positioning screws 43.
[0068] Preferably, the connecting sleeve 42 can be made of a round steel tube, and a rectangular socket matching the first frame 2 is formed by welding steel plates inside the round steel tube for matching and inserting the first frame 2, thereby preventing the first frame 2 and the connecting sleeve 42 from rotating relative to each other. The first frame 2 and the connecting sleeve 42 are connected by bolts along the radial direction of the connecting sleeve 42 through the first positioning screw hole 22 and the third positioning screw hole 44, which has strong shear resistance and high connection reliability, and is not prone to loosening or even falling off after frequent vibration.
[0069] Please see the attached Figure 4 To the attached Figure 6 A plurality of second positioning screw holes 32 are formed at both ends of the second skeleton 3, and a plurality of third positioning screw holes 44 are formed on the connecting sleeve 42, so that when the connecting sleeve 42 is sleeved on the end of the second skeleton 3, the plurality of second positioning screw holes 32 are respectively aligned with the plurality of third positioning screw holes 44, so that the second skeleton 3 is fixedly connected to the connecting sleeve 42 through the second positioning screw holes 32 and the third positioning screw holes 44 by the positioning screws 43.
[0070] Similarly, the second frame 3 is inserted into the connecting sleeve 42 to prevent the second frame 3 from rotating relative to the connecting sleeve 42. Bolts are used to connect the second frame 3 and the connecting sleeve 42 along the radial direction of the connecting sleeve 42 through the second positioning screw hole 32 and the third positioning screw hole 44, which has strong shear resistance and high connection reliability, and is not prone to loosening or even falling off after frequent vibration.
[0071] Please see the attached Figure 1 To the attached Figure 8 A construction method for a keel structure system of a spatial hyperbolic special-shaped curtain wall comprises the following steps:
[0072] Step 1: Install the connecting mechanisms 4 at both ends of the second skeleton 3, and arrange the connecting mechanisms 4 of two adjacent second skeletons 3 relatively and rotatably connect them through the steering mechanism 5 to form an adjustable special-shaped keel.
[0073] Specifically, place the connecting sleeve 42 onto the second frame 3 and secure the connecting sleeve 42 to the second frame 3 using the set screws 43 through the second and third set screw holes. Position the open ends of the rotating connectors 41 on two adjacent second frames 3 opposite each other, place the rotating base 53 at the open ends of the two rotating connectors 41, and vertically connect the open ends of the two rotating connectors 41. Screw the stud bolt 51 onto the open end of the rotating connector 41 and the rotating base 53. Repeat these steps until all second frames 3 are connected, forming an adjustable special-shaped keel.
[0074] Step 2: Install the connecting mechanism 4 at one end of the first frame 2, and arrange the connecting mechanisms 4 on a pair of first frames 2 and the connecting mechanisms 4 at both ends of the adjustable special-shaped keel opposite to each other and rotatably connect them through the steering mechanism 5.
[0075] The manner in which the connecting mechanism 4 is mounted on the first frame 2 is the same as the manner in which the connecting mechanism 4 is mounted on the second frame 3, and will not be described in detail here. The manner in which the first frame 2 and the second frame 3 are rotationally connected via the connecting mechanism 4 through the steering mechanism 5 is the same as the manner in which two adjacent second frames 3 are rotationally connected via the connecting mechanism 4 through the steering mechanism 5, and will not be described in detail here.
[0076] Step 3: Adjust the curvature of the adjustable special-shaped keel through the steering mechanism 5 and lock the steering mechanism 5.
[0077] Specifically, the two vertically connected rotating connectors 41 are rotated and adjusted so that they rotate about the rotating base 53, adjusting the two adjacent second frames 3 to a specified arc, and adjusting the first frame 2 and the second frame 3 to a specified arc. After the adjustment is completed, the stud bolt 51 is screwed in, and the thrust bearing 54 and the first limiting ring 55 are tightened and fixed between the rotating base 53 and the open end of the rotating connector 41. The stud bolt 51 is then locked to the rotating connector 41 using the locking nut 52.
[0078] Step 4: Install the fixing base 1 at the other end of the first frame 2 , and the adjustable special-shaped keel is installed and fixed on the building structure through the fixing base 1 .
[0079] Specifically, the fixing base 1 can adopt a square structure, the top and two sides of the fixing base 1 are fixed to the first frame 2 by screws, and the bottom of the fixing base 1 is fixedly connected to the first frame 2 by screws through the fixing frame 11, and the fixing base 1 is fixedly installed on the building structure by screws.
[0080] Step 5: Install the curtain wall on the second frame 3 through the fixing mechanism 6, and absorb noise vibration through the fixing mechanism 6.
[0081] Specifically, one end of the sliding sleeve 611 is vertically welded to the side of the second frame 3. The screw cap 62 is rotatably mounted on the sliding sleeve 611 via a second retaining ring 612. A vibration damping plate 634 is connected to the inner wall of the third fixing plate 636 of the sliding sleeve 631 via a vibration damping spring 635. The vibration damping plate 634 is screwed onto the inner wall of the sliding sleeve 631 via threads, fitting the inner wall of the curtain wall onto the third fixing plate 636. One end of the sliding sleeve 631 is coaxially screwed to the screw cap 62 via a male connector 632. The sliding sleeve 631 is then sleeved onto the exterior of the sliding sleeve 611. The first fixing plate 621 and the second fixing plate 633 are fitted together and secured with bolts.
[0082] After the curtain wall absorbs the sound wave vibration, part of the sound wave vibration is transmitted through the outer wall of the sliding sleeve 631 and is absorbed by the first fixing plate 621 and the second fixing plate 633 and the vibration-damping pad and the anti-slip pad therebetween. Another part of the sound wave vibration is transmitted through the inner cavity of the sliding sleeve 631 and is amplified by the Helmholtz resonator-type structure and acts on the vibration-damping plate 634, causing the vibration-damping plate 634 to translate and stretch the vibration-damping spring 635. At the same time, the translational motion of the vibration-damping plate 634 is converted into the rotational motion of the sliding sleeve 631 by using the thread, so that the sliding sleeve 631 and the spiral fixing cap 62 rotate synchronously. The sliding sleeve 631 is relative to the cleaning rod 637, and the plush clusters of the cleaning rod 637 slide and rub on the surface of the sliding sleeve 631 to achieve a cleaning effect.
[0083] The above are only preferred embodiments of the present invention and are not intended to limit the scope of protection of the invention. Therefore, any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
