A prefabricated soundproof partition wall with vibration damping structure

Abstract

This utility model discloses a prefabricated soundproof partition wall with a shock-absorbing structure, including a wall frame. Multiple evenly distributed connecting sleeves are fixedly connected to both ends of the wall frame. A pair of wall sections are slidably connected to the inner wall of the wall frame. The partition wall also includes a shock-absorbing component and a sound-insulating component disposed inside the wall frame. The shock-absorbing component includes multiple grooves formed at both ends of the wall frame near the connecting sleeves. A pair of guide sleeves are fixedly connected to the inner top of each connecting sleeve. A guide rod is slidably connected to the inner peripheral wall of each guide sleeve, and a spring is sleeved on the outer peripheral wall of each guide rod. This utility model utilizes the movement of the shock-absorbing block to compress the sliding block, which in turn compresses the spring, simultaneously driving the guide rod towards the guide sleeve. This converts the kinetic energy of the wall into the elastic potential energy of the spring, preventing external impacts from causing the wall to crack or break, thus effectively improving the shock absorption effect of the partition wall.

Description

Technical Field

[0001] This utility model relates to the field of prefabricated partition wall technology, and in particular to a prefabricated soundproof partition wall with a shock-absorbing structure. Background Technology

[0002] Traditional prefabricated partition walls are widely used in the construction industry, but they generally suffer from insufficient shock absorption and limited sound insulation.

[0003] A search revealed Chinese patent CN219794314U, which discloses a prefabricated partition wall panel with multiple sound insulation structures, including a frame and connecting plates. The inner wall of the frame is fixedly connected to the main body of the partition wall panel. This partition wall can enhance the sound insulation effect of the prefabricated partition wall panel through multiple sound insulations. At the same time, the overall structure of the prefabricated partition wall panel can be disassembled without damaging it, which is conducive to the recycling of the prefabricated partition wall panel.

[0004] However, the partition wall also has the following defects: the partition wall frame, connecting plate and the main body of the partition wall are all rigidly fixed. When subjected to external impact, it is easy to transmit vibration, resulting in structural damage and making it difficult to effectively improve the vibration reduction effect of the partition wall. Utility Model Content

[0005] The purpose of this utility model is to address the shortcomings of existing technologies by proposing a prefabricated soundproof partition wall with a shock-absorbing structure.

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

[0007] A prefabricated soundproof partition wall with a shock-absorbing structure includes a wall frame, with multiple evenly distributed connecting sleeves fixedly connected to both ends of the wall frame, a pair of wall bodies slidably connected to the inner wall of the wall frame, and also includes a shock-absorbing component and a sound-insulating component disposed inside the wall frame.

[0008] The vibration damping assembly includes multiple grooves located at both ends of the wall frame near the connecting sleeves. Each connecting sleeve has a pair of guide sleeves fixedly connected to its inner top. Each guide sleeve has a guide rod slidably connected to its inner circumferential wall. Each guide rod has a spring fitted onto its outer circumferential wall. Each pair of guide rods has a sliding block fixedly connected to its bottom end, and the sliding block is slidably connected to the groove. Both ends of each spring are fixedly connected to the top of the sliding block and the bottom of the guide sleeve. The sliding block has an isosceles trapezoidal structure. Each wall's inner wall near the groove has a damping block adapted to the sliding block. Through the isosceles trapezoidal structure of the groove and the sliding block, vertical impact is converted into inclined sliding, and with the spring's energy dissipation, wall resonance is reduced.

[0009] Each of the wall components has a pair of guide blocks fixedly connected to both ends, and each guide block has rolling ball bearings connected to both ends. The inner wall of each wall frame has a second sliding groove near the guide blocks, and this second sliding groove is adapted to the guide blocks and rolling ball bearings. Each wall component and the outer wall of each wall frame has multiple limiting grooves near the second sliding groove. One end of each pair of limiting grooves is connected to a limiting plate, and one end of each limiting plate is threaded with a fastening bolt. The guide blocks and rolling ball bearings roll within the second sliding groove, reducing assembly friction and preventing installation misalignment.

[0010] Preferably, each of the damping blocks is arranged in a trapezoidal structure, and the inclined surface of each sliding block is in contact with the inclined surface of the adjacent pair of damping blocks, and the contact surface between the sliding block and the damping block is smoothed. The smoothed contact surface reduces friction noise and improves sliding smoothness.

[0011] Preferably, one pair of the connecting sleeves is coaxially arranged with the wall frame, and the remaining connecting sleeves are arranged parallel to one pair of connecting sleeves.

[0012] Preferably, the sound insulation component includes a sound insulation layer fixedly connected between the inner walls of both sides of the wall frame, and the sound insulation layer is located in the exact center inside the wall frame. The centrally positioned sound insulation layer blocks the superposition of sound waves from both sides, and is particularly effective in absorbing mid-to-high frequency noise.

[0013] Preferably, a pair of heat insulation layers are fixedly connected to the inner wall of the wall frame near the sound insulation layer, and the pair of heat insulation layers are symmetrically distributed along the sound insulation layer. The symmetrical heat insulation layers suppress wall deformation caused by temperature gradients and prevent the sound insulation layer from failing due to thermal expansion and contraction.

[0014] Preferably, a pair of buffer layers are fixedly connected to the inner wall of the wall frame near the insulation layer, and the outer wall of the buffer layer is in contact with the inner wall of the wall. The buffer layer and the inner wall of the wall are in contact to fill the installation gap, further absorbing energy and reducing vibration.

[0015] The beneficial effects of this utility model are as follows:

[0016] 1. By moving the damping block to compress the sliding block, and then the sliding block compresses the spring, the guide rod moves towards the guide sleeve, which converts the kinetic energy of the wall into the elastic potential energy of the spring, thus preventing the wall from cracking or breaking due to the impact of external forces and effectively improving the shock absorption effect of the partition wall.

[0017] 2. By combining the buffer layer and the sound insulation layer, the sound insulation effect of the partition wall is improved, thus enhancing the overall functionality and practicality of the partition wall. Attached Figure Description

[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0024] Example 1, referring to Figure 1-4 A prefabricated soundproof partition wall with a shock-absorbing structure includes a wall frame 1. Both ends of the wall frame 1 are fixedly connected with multiple evenly distributed connecting sleeves 2 by bolts. One pair of connecting sleeves 2 is coaxially arranged with the wall frame 1, and the remaining connecting sleeves 2 are arranged parallel to one pair of connecting sleeves 2. The connecting sleeves 2 are made of high-strength composite material to improve the overall structural strength and stability of the partition wall. A pair of wall bodies 3 are slidably connected to the inner wall of the wall frame 1. The partition wall also includes shock-absorbing components and sound-insulating components disposed inside the wall frame 1.

[0025] like Figures 2-4As shown, in one embodiment, to improve the vibration damping effect of the partition wall, the vibration damping component includes multiple grooves 201 opened at both ends of the wall frame 1 near the connecting sleeves 2. A pair of guide sleeves 4 are fixedly connected to the inner top of each connecting sleeve 2 by welding. A guide rod 5 is slidably connected to the inner peripheral wall of each guide sleeve 4. A spring 6 is sleeved on the outer peripheral wall of each guide rod 5, wherein the spring 6 serves to store energy and drive the guide rod 5 to reset. A sliding block 7 is fixedly connected to the bottom end of each pair of guide rods 5, and the sliding block 7 is slidably connected to the groove 201. Next, both ends of each spring 6 are fixedly connected to the top of the sliding block 7 and the bottom of the guide sleeve 4. The sliding block 7 is arranged in an isosceles trapezoidal structure. Each inner wall of the wall 3 is fixedly connected to a damping block 8 that is adapted to the sliding block 7 near the slide groove 201. Each damping block 8 is arranged in a trapezoidal structure. The inclined surface of each sliding block 7 is in contact with the inclined surface of the adjacent pair of damping blocks 8. The contact surface between the sliding block 7 and the damping block 8 is smooth. Through the mutual cooperation between the damping block 8 and the sliding block 7, the horizontal vibration of the wall 3 is converted into the vertical vibration of the sliding block 7.

[0026] like Figure 3 and Figure 4 As shown, in one embodiment, in order to improve the stability of the partition wall, a pair of guide blocks 9 are fixedly connected to both ends of each wall 3, and roller balls 10 are rolledly connected to both ends of each guide block 9. A second sliding groove 11 is opened on the inner wall of the wall frame 1 near the guide block 9, and the second sliding groove 11 is adapted to the guide block 9 and the roller balls 10. Through the mutual cooperation between the guide block 9, the roller balls 10 and the second sliding groove 11, the movement direction of the wall 3 is further limited. Multiple limiting grooves 12 are opened on the outer wall of each wall 3 and the wall frame 1 near the second sliding groove 11. One end of each pair of limiting grooves 12 is connected to a limiting plate 13. One end of each limiting plate 13 is threadedly connected to a fastening bolt 14. Through the mutual cooperation between the fastening bolt 14 and the limiting plate 13, the wall 3 is prevented from detaching from the wall frame 1.

[0027] like Figure 3 and Figure 4As shown, in one embodiment, to further enhance the functionality of the partition wall, the sound insulation component includes a sound insulation layer 15 fixedly connected between the inner walls on both sides of the wall frame 1, and the sound insulation layer 15 is located in the center inside the wall frame 1. The sound insulation layer 15 is made of sound-insulating aluminum foam material to improve the sound insulation effect of the partition wall. A pair of heat insulation layers 16 are fixedly connected to the inner wall of the wall frame 1 near the sound insulation layer 15, and the pair of heat insulation layers 16 are symmetrically distributed along the sound insulation layer 15. The heat insulation layers 16 play a fireproof role. A pair of buffer layers 17 are fixedly connected to the inner wall of the wall frame 1 near the heat insulation layer 16, and the outer wall of the buffer layer 17 is attached to the inner wall of the wall 3. The buffer layer 17 is made of polyimide gradient foam material and plays a preliminary role in sound insulation, heat insulation and shock absorption.

[0028] Working Principle: During assembly, the connecting sleeve 2 is first embedded in the designated mounting hole. Then, the wall frame 1 is fixedly connected to the connecting sleeve 2 with bolts. Next, a pair of wall bodies 3 are installed at the designated positions on the wall frame 1. The mutual cooperation between the limiting plate 13 and the fastening bolt 14 prevents the wall bodies 3 from detaching from the wall frame 1. After assembly, when the wall body 3 is impacted by external force, the wall body 3 drives the shock-absorbing block 8 to move and compress the sliding block 7. Then, the sliding block 7 compresses the spring 6, and at the same time, it drives the guide rod 5 to move towards the guide sleeve 4. This converts the kinetic energy of the wall body 3 into the elastic potential energy of the spring 6, preventing the wall body 3 from cracking or breaking due to the impact of external force, effectively improving the shock absorption effect of the partition wall. At the same time, the inner wall of the wall body 3 compresses the buffer layer 17, causing the buffer layer 17 to deform and absorb energy, further improving the shock absorption effect of the partition wall. Then, through the mutual cooperation between the buffer layer 17 and the sound insulation layer 15, the sound insulation effect of the partition wall is improved, enhancing the overall functionality and practicality of the partition wall.

[0029] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
