Description

Technical Field

[0001] This utility model relates to the field of architectural acoustics engineering, and in particular to a truss large-span sound absorption and noise reduction installation structure. Background Technology

[0002] In fields such as noise reduction in construction and industrial equipment, the fixed installation of sound-absorbing components often faces problems such as extremely large spans, high installation difficulty, high cost, poor convenience, and visual interference. Traditional fixing methods mostly use rigid connections or simple suspensions, which are prone to uneven stress, causing sound-absorbing components to sway, shift, or even fall off, posing safety hazards and affecting noise reduction effects. At the same time, the smooth surface of the fixing structure is prone to light reflection, causing visual discomfort, and the lack of a precise positioning structure during installation requires repeated adjustments, which is time-consuming and labor-intensive. Often, the cost of making and installing the frame for a single sound-absorbing component far exceeds the cost of the component itself. Therefore, there is an urgent need for a sound-absorbing component fixing structure that features large spans, stable structure, convenient installation, low cost, and both visual optimization and mechanical stability. Utility Model Content

[0003] The purpose of this utility model is to provide a truss large-span sound-absorbing and noise-reducing installation structure, which solves the above-mentioned problems.

[0004] This utility model is achieved through the following technical solution: A truss long-span sound absorption and noise reduction installation structure includes a C-shaped frame disposed between trusses, a tensioned braided steel wire rope disposed between the trusses, and an elastic bearing part disposed on the C-shaped frame in the axial direction of the braided steel wire rope, which can suspend the C-shaped frame on the braided steel wire rope.

[0005] Furthermore, The cross-section of the elastic bearing part is "7" shaped and the horizontal end of the elastic bearing part is connected to the side of the C-shaped frame. The vertical part of the elastic bearing part is inclined to the side of the C-shaped frame and a horizontal anti-detachment hook is also provided in the vertical part.

[0006] Furthermore, Several anti-glare grooves are formed on the outer surface of the elastic bearing part along the length of the elastic bearing part, and a screw positioning groove is formed below the anti-glare groove on the outer surface of the vertical part of the elastic bearing part. An anti-slip groove for braiding steel wire rope is formed on the inner surface of the elastic bearing part.

[0007] Furthermore, The distance between the anti-detachment hook and the C-shaped frame is less than or equal to the diameter of the braided steel wire rope.

[0008] Furthermore, The braided steel wire rope is tensioned by wrapping around the truss or large-span building components and passes through the elastic load-bearing parts on both sides of the C-shaped frame, so as to make the C-shaped frame evenly stressed.

[0009] Furthermore, The outer side surface of the C-shaped frame has several intervals from top to bottom around the frame and recessed positioning grooves along the intervals. Several anti-glare grooves are opened on the upper and lower surfaces of the C-shaped frame. An elastic bearing part for placing sound-absorbing and noise-reducing panels is provided at the bottom of the C-shaped frame. An "I"-shaped strong partition is set in the middle of the C-shaped frame. There are protruding screw fixing grooves on both sides of the "I"-shaped strong partition in the C-shaped frame.

[0010] Furthermore, The braided steel wire rope is fixed around the truss or large-span building component by fasteners. When the braided steel wire rope forms a "loop" grid on the truss or large-span building component, an annular sleeve is installed on the adjacent surface of the C-shaped frame where the elastic bearing part is installed. This sleeve works in conjunction with the elastic bearing part to achieve the installation of the braided steel wire rope.

[0011] Furthermore, The fasteners include sleeves and rope clips, and the orientation of the fasteners is alternated.

[0012] Furthermore, The recessed positioning grooves correspond to the screw fixing grooves on the "I"-shaped strong partition, thereby improving assembly efficiency.

[0013] Furthermore, The screw positioning groove on the outer surface of the elastic bearing part corresponds to the first concave positioning groove on the C-shaped frame from top to bottom.

[0014] The beneficial effects of this utility model are: 1. By weaving steel wire ropes around the truss, tensioning them, and passing them through the anti-slip grooves on the inner surface of the elastic bearing section (the width of which matches the diameter of a single steel wire rope), a rigid support structure is formed. The C-shaped frame is suspended and installed using truss support, which greatly saves costs and speeds up the construction period. It is suitable for high-altitude installation scenarios such as suspended ceilings. The anti-slip grooves and steel wire ropes are tightly engaged, preventing the C-shaped frame from sliding or swaying due to gravity when suspended, thus improving the reliability and safety of the connection.

[0015] 2. The anti-disengagement hook of the elastic load-bearing part and the concave positioning groove on the side of the C-shaped frame form a "mortise and tenon" fit. During installation, the anti-disengagement hook is fixed into the positioning groove by screws, which can quickly complete the lateral limit and prevent the frame from swaying left and right, thus improving the installation efficiency. At the same time, the screw fixing groove of the "I"-shaped strong partition in the middle of the C-shaped frame limits the upper and lower parts of the sound-absorbing and noise-reducing plate to prevent it from falling off.

[0016] 3. The braided steel wire rope is fixed to the large-span structural members of the building by fasteners, and the openings of the fasteners are arranged alternately to distribute the force evenly, avoid stress concentration between adjacent fasteners, and improve the overall wind load and seismic resistance. The screw positioning groove on the outer surface of the elastic bearing part provides position guidance and convenience for screw installation, and enhances the stability of the connection between the elastic bearing part and the C-shaped frame.

[0017] 4. Anti-glare grooves are provided on the surface of the elastic load-bearing part and the C-shaped frame. This not only reduces the reflection of external light and improves visual comfort, but also increases the surface roughness and enhances the friction with screws and other components to prevent slippage. The segmented and spaced anti-glare groove design avoids screws from damaging the groove, taking into account both practicality and structural integrity. Attached Figure Description

Detailed Implementation

[0020] The present invention will be further described in detail below with reference to the embodiments and accompanying drawings, but the embodiments of the present invention are not limited thereto.

[0021] In the description of this utility model, it should be noted that the terms "center", "upper", "lower", "left", "right", "vertical", "longitudinal", "lateral", "horizontal", "inner", "outer", "front", "rear", "top", "bottom", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings, or the orientation or positional relationship commonly used when the utility model product is in use. They are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model.

[0022] In the description of this utility model, it should also be noted that, unless otherwise explicitly specified and limited, the terms "set up," "have," "install," "connect," and "connect" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0023] See the example. Figures 1 to 7 : A truss long-span sound absorption and noise reduction installation structure includes a C-shaped frame 1 disposed between trusses 14, a tensioned braided steel wire rope 3 disposed between the trusses 14, and an elastic bearing part 2 disposed on the C-shaped frame 1 in the axial direction of the braided steel wire rope 3, which can suspend the C-shaped frame 1 on the braided steel wire rope 3.

[0024] Furthermore, The cross-section of the elastic bearing part 2 is "7" shaped and the horizontal end of the elastic bearing part 2 is connected to the side of the C-shaped frame 1. The vertical part of the elastic bearing part 2 is inclined to the side of the C-shaped frame 1 and a horizontal anti-detachment hook 4 is also provided in the vertical part.

[0025] The elastic bearing part 2 is shaped like a "7". The horizontal end is in close contact with the side of the C-shaped frame 1 to form a stable support base, while the vertical part is inclined to the side of the C-shaped frame 1, which can guide the braided steel wire rope 3 to smoothly enter the inner surface of the elastic bearing part 2 when suspended.

[0026] Furthermore, Several anti-glare grooves 5 are formed on the outer surface of the elastic bearing part 2 along the length of the elastic bearing part 2, and a screw positioning groove 6 is formed below the anti-glare grooves 5 on the outer surface of the vertical part of the elastic bearing part 2. An anti-slip groove 7 for braiding steel wire rope 3 is formed on the inner surface of the elastic bearing part 2.

[0027] The anti-glare grooves 5 on the outer surface of the multiple elastic bearing parts 2 can disperse external light reflections and avoid visual discomfort caused by the smooth surface. At the same time, the grooves increase the surface roughness, enhance the friction with the screws, and prevent the screws from loosening. The screw positioning grooves 6 in the vertical part provide precise position guidance for the installation of screws, avoid repeated measurements during installation, and improve construction efficiency. The anti-slip grooves 7 on the inner surface match the diameter of the wire rope. By interlocking with the surface texture of the braided wire rope 3, the slippage of the C-shaped frame 1 when suspended is reduced, and the friction and stability of the connection are enhanced.

[0028] Furthermore, The distance between the anti-detachment hook 4 and the C-shaped frame 1 is less than or equal to the diameter of the braided steel wire rope 3.

[0029] When the braided steel wire rope 3 passes through the elastic bearing part 2, the gap between the anti-detachment hook 4 and the C-shaped frame 1 is smaller than the diameter of the steel wire rope, forming a physical barrier that prevents the steel wire rope from coming off the elastic bearing part 2. This effectively prevents the C-shaped frame 1 from detaching from the steel wire rope under the action of external forces such as wind and vibration. It is especially suitable for wind load and seismic resistance requirements in large span scenarios, thus eliminating the safety hazard of suspension parts falling off.

[0030] In one embodiment, the braided steel wire rope 3 has a diameter of 8mm, and the distance between the anti-detachment hook 4 and the C-shaped frame 1 is set to 7mm. Under the airflow disturbance generated by the operation of the exhibition hall's air conditioning system, the C-shaped frame 1 remains stable due to the limiting effect of the anti-detachment hook 4, without shaking or falling off, thus ensuring the continuity of the sound absorption effect.

[0031] Furthermore, The braided steel wire rope 3 is tensioned around the truss 14 or the large-span structural member and passes through the elastic bearing parts 2 on both sides of the C-shaped frame 1 to ensure uniform force distribution on the C-shaped frame 1.

[0032] After the steel wire rope is tensioned around the truss 14 or the large-span building components, it forms a through rigid support system. When it passes through the elastic bearing parts 2 on both sides of the C-shaped frame 1, it can evenly distribute the weight of the C-shaped frame 1 to multiple stress points of the steel wire rope, avoiding stress concentration at a single point. The load-bearing capacity of the truss 14 is used to realize the suspended installation of the C-shaped frame 1 without the need to build an additional installation frame, saving costs. At the same time, the uniform stress design improves the deformation resistance of the overall structure. In one embodiment, during the noise reduction renovation of the factory workshop, the braided steel wire rope 3 is stretched in a grid pattern around the truss 14 at the top of the workshop. The C-shaped frame 11 is inserted into the protrusion of the braided steel wire rope 3 through the anti-slip grooves 77 of the elastic bearing parts 22 on both sides. The steel wire rope is evenly distributed with force. The C-shaped frame 1 does not tilt after being suspended. Even if the equipment in the workshop vibrates during operation, the C-shaped frame 1 remains stable and effectively absorbs machine noise. For the mesh-like braided steel wire rope 3, the C-shaped frame 1 has an annular sleeve 16 on the side without the elastic bearing part 2. Figure 6 As shown, the elastic bearing part 2 and the annular sleeve 16 are in contact with the transverse and longitudinal braided steel wire ropes 3 respectively so that the braided steel wire ropes 3 support the elastic bearing part 2 and the annular sleeve 16, thereby supporting the C-shaped frame 1. The inner side of the annular sleeve 16 has the same anti-slip groove 7 as the inner side of the elastic bearing part 2.

[0033] Furthermore, The outer side surface of the C-shaped frame 1 has several intervals 10 formed from top to bottom around the frame, and recessed positioning grooves 8 are formed along the intervals 10. Several anti-glare grooves 5 are formed on the upper and lower surfaces of the C-shaped frame 1. An elastic bearing part 2 for placing a sound-absorbing and noise-reducing plate 15 is provided at the bottom of the C-shaped frame 1. An "I"-shaped strong partition 12 is provided in the middle of the C-shaped frame 1. There are protruding screw fixing grooves 13 on both sides of the "I"-shaped strong partition 12 on the C-shaped frame 1.

[0034] The recessed positioning groove 8 on the side of the C-shaped frame 1 corresponds to the screw fixing groove 13 of the "I"-shaped strong partition 12, and the "mortise and tenon" positioning can be achieved by screws to ensure that the sound-absorbing and noise-reducing board 15 is limited in the upper and lower and left and right directions during installation, and to prevent the sound-absorbing and noise-reducing board 15 from falling off; the anti-glare grooves 5 on the upper and lower surfaces of the C-shaped frame 1 reduce light reflection and improve visual comfort; the bottom bearing plate 11 provides a support platform for the sound-absorbing and noise-reducing board 15, and the middle "I"-shaped strong partition 12 enhances the overall rigidity of the C-shaped frame 1 and avoids the deformation of the C-shaped frame 1 under large spans. The segmented recessed positioning grooves 8 can also prevent the groove structure of the anti-glare grooves 5 from being damaged during screw installation.

[0035] Furthermore, The braided steel wire rope 3 is fixed around the truss 14 or the building's large-span components by fasteners 9. When the braided steel wire rope 3 forms a "return" grid on the truss 14 or the building's large-span components, an annular sleeve 16 is installed on the adjacent surface of the C-shaped frame 1 where the elastic bearing part 2 is installed, which works together with the elastic bearing part 2 to achieve the installation of the braided steel wire rope 3.

[0036] In one embodiment, an opening of the same length as the annular sleeve 16 is formed along the axial direction below the annular sleeve 16. The cross-section of the opening is a trapezoid that gradually narrows towards the center of the annular sleeve 16. The opening width inside the annular sleeve 16 is smaller than the diameter of the braided steel wire rope 3. When the C-shaped frame 1 is installed, the braided steel wire rope 3 is squeezed at the opening inside the annular sleeve 16, causing the annular sleeve 16 to deform and allowing the braided steel wire rope 3 to enter the annular sleeve 16. After installation, due to the influence of gravity, the upper part of the annular sleeve 16 is always in contact with the braided steel wire rope 3, and the diameter of the braided steel wire rope 3 is larger than the width of the opening inside the annular sleeve 16, preventing the braided steel wire rope 3 from detaching from the annular sleeve 16 at the opening.

[0037] Furthermore, The fastener 9 includes a sleeve and a rope clip, and the orientation of the fastener 9 is alternately set.

[0038] The fasteners 9 (sleeves, rope clips) are used to securely fix the wire rope to the truss 14 and other components, ensuring the stability of the wire rope after tensioning. The openings of the fasteners 9 are arranged in alternating directions, which can make the stress of adjacent fixing points cancel each other out, avoid local stress concentration that may cause the wire rope to loosen or break, improve the wind load and seismic resistance of the overall structure, and ensure the reliability of long-term use in large-span environments.

[0039] In one embodiment, the braided steel wire rope 3 is tensioned around the bridge truss 14 and secured with rope clips. When the fastener 9 is installed, the opening directions of adjacent rope clips alternately face left and right, so that the force on the steel wire rope at the fixing point is evenly distributed.

[0040] Furthermore, The recessed positioning grooves 8 correspond to the screw fixing grooves 13 on the "I"-shaped strong partition 12.

[0041] The correspondence between the recessed positioning groove 8 and the screw fixing groove 13 provides a precise positioning reference for the installation of the sound-absorbing and noise-reducing plate 15. The screw can pass through both the recessed positioning groove 8 and the screw fixing groove 13 simultaneously, fixing the "I"-shaped strong partition 12 to the C-shaped frame 1. At the same time, the screw fixing groove 13 on the "I"-shaped strong partition 12 is above the sound-absorbing and noise-reducing plate 15, which has an upper and lower limiting effect on the sound-absorbing and noise-reducing plate 15, preventing it from shaking or falling off within the C-shaped frame 1.

[0042] Furthermore, The screw positioning groove 6 on the outer surface of the elastic bearing part 2 corresponds to the first concave positioning groove 8 on the C-shaped frame 1 from top to bottom.

[0043] The nail positioning groove provides position guidance for the fixing screws of the elastic bearing part 2, and corresponds to the first concave positioning groove 8 of the C-shaped frame 1. This ensures that the installation position of the elastic bearing part 2 on the C-shaped frame 1 is accurate, and that the anti-disengagement hook 4 of the elastic bearing part 2 forms a correct limiting fit with the positioning groove on the side of the C-shaped frame 1. This prevents the C-shaped frame 1 from shaking or falling off due to installation deviation, and improves the installation efficiency and stability of the overall structure.

[0044] Installers quickly determine the screw hole positions using the positioning slots and fix the elastic bearing part 2 to both sides of the C-shaped frame 1. Due to the precise positioning, after the braided steel wire rope 3 passes through the elastic bearing part 2, the anti-disengagement hook 4 accurately engages with the positioning slot of the C-shaped frame 1. The C-shaped frame 1 hangs without shifting, which reduces installation and debugging time and improves construction efficiency.

[0045] The method of using this utility model is as follows: When in use, first wrap the braided steel wire rope 3 around the truss 14 or the large span component of the building, and then tighten and fix it by using the fasteners 9, which include sleeves and rope clips with their openings facing the alternating fasteners. The alternating fasteners 9 make the stress of adjacent fixing points cancel each other out, avoid local stress concentration, and ensure that the steel wire rope is subjected to uniform and stable force.

[0046] Subsequently, the “7”-shaped elastic bearing parts 2 on both sides of the C-shaped frame 1 are installed on the side of the C-shaped frame 1. The horizontal end of the elastic bearing part 2 is connected to the side of the C-shaped frame 1, and its vertical part is inclined to the side of the C-shaped frame 1. The anti-slip groove 7 opened on the inner surface matches the diameter of the braided steel wire rope 3. During installation, the braided steel wire rope 3 is passed through the anti-slip groove 7 on the inner surface of the elastic bearing part 2. The tight engagement between the anti-slip groove 7 and the surface texture of the steel wire rope increases the friction and prevents the C-shaped frame 1 from sliding or shaking due to gravity. Meanwhile, the horizontal anti-detachment hook 4 set in the vertical part of the elastic bearing part 2 corresponds to the concave positioning groove 8 on the side of the C-shaped frame 1. Since the distance between the anti-detachment hook 4 and the C-shaped frame 1 is less than the diameter of the braided steel wire rope 3, a physical barrier is formed to prevent the steel wire rope from coming out, thereby achieving lateral limitation and preventing the frame from swaying left and right.

[0047] After the C-shaped frame 1 is installed, a sound-absorbing and noise-reducing plate 15 is placed on the support plate 11 at its bottom. The screw fixing grooves 13 protruding on both sides of the "I"-shaped strong partition 12 in the middle of the C-shaped frame 1 correspond to the recessed positioning grooves 8 opened along the interval 10 on the outer surface of the side of the C-shaped frame 1. The screws are used to fix the plate, thus limiting the upper and lower positions of the sound-absorbing and noise-reducing plate 15 and preventing it from falling off. In addition, the anti-glare grooves 5 opened along the length of the outer surface of the elastic support part 2 can reduce light reflection and improve visual comfort. At the same time, it increases the surface roughness, enhances the friction with the screws, and prevents the screws from loosening. The design of the anti-glare grooves 5 on the upper and lower surfaces of the C-shaped frame 1 and the segmented recessed positioning grooves 8 not only reduces light reflection but also avoids damage to the groove structure by screw installation, ensuring practicality and structural integrity.

[0048] The entire structure forms a rigid support system by woven steel wire rope 3 around the truss 14. The C-shaped frame 1 is suspended and installed using the support of the truss 14, eliminating the need for an additional skeleton and saving costs. Furthermore, through multiple limiting structures such as the elastic load-bearing part 2, anti-detachment hook 4, anti-slip groove 7, and "I"-shaped strong partition 12, the sound-absorbing components are ensured to be subjected to uniform stress and reliable connection in a large span environment, effectively coping with the effects of external forces such as wind and vibration.

[0049] The specific embodiments described above further illustrate the purpose, technical solution, and beneficial effects of this utility model. It should be understood that the above description is only a specific embodiment of this utility model and is not intended to limit the scope of protection of this utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the scope of protection of this utility model.
