Description

Technical Field

[0001] The invention relates to the technical field of sound insulation wall panels, in particular to a hanging sound insulation wall panel. Background Art

[0002] In order to reduce the interference of external noise on the interior, sound insulation wall panels are installed on the walls of the building. The sound insulation wall panels are made of sound insulation materials and have a good isolation effect on external noise. Traditional integral sound insulation wall panels are inconvenient to transport, and once they are damaged during use, they need to be replaced as a whole, which is very costly. Therefore, they are gradually replaced by modular sound insulation wall panels. When installing modular sound insulation wall panels, the single panels need to be installed in the corresponding position on the bracket to form a whole.

[0005] Existing modular soundproof wall panels are basically installed on the frame by fasteners such as bolts. When the external temperature is high, the wall panels will expand slightly, which will cause the interaction between the fasteners and the frame. After long-term use, the fasteners and the frame will become loose, affecting the stability of the wall panels. In addition, adjacent wall panels will squeeze each other when the volume expands, causing irreversible deformation. Summary of the invention

[0006] The object of the present invention is to provide a suspended sound insulation wall panel to solve the above-mentioned deficiencies in the prior art.

[0007] In order to achieve the above-mentioned purpose, the present invention provides the following technical solutions: a suspended sound insulation wall panel, comprising a frame and a plurality of plate bodies, wherein the plurality of plate bodies are arranged in layers, the number of plate bodies in each layer is the same, and the surface of the plate bodies is coated with sound-absorbing material; a first round rod and a second round rod are horizontally fixedly installed at the position corresponding to each layer of the plate bodies on the frame; the first round rod is located above the second round rod and parallel to the second round rod.

[0008] The middle part of the plate body protrudes toward the side away from the frame, and a hook claw matching the corresponding first round rod is installed on the plate body, and a supporting claw matching the corresponding second round rod is also installed on the plate body; a first compensation strip is fixedly installed horizontally on the top surface of the plate body, and a second compensation strip is fixedly installed horizontally on the bottom surface of the plate body.

[0011] As a preferred technical solution of the present invention, a notch is provided on the first round rod at a position corresponding to each plate body, and the hook claw and the plate body are slidably matched along a direction parallel to the axis of the first round rod.

[0012] As a preferred technical solution of the present invention, two hooks and two supporting claws are installed on each plate body, a first cable is fixedly installed on the side of each hook facing away from the other hook, and a second cable is fixedly installed on the side of each hook facing the other hook.

[0016] In the above technical scheme, the present invention provides a hanging sound insulation wall panel, which does not use traditional fasteners such as bolts to install the panel on the frame, but suspends the panel through the cooperation between the hook and the first round rod, and the support claw and the second round rod; after the installation is completed, the first round rod plays a role of limiting the vertical direction of the hook, the support claw and the panel, and the second round rod plays a role of limiting the horizontal direction of the hook, the support claw and the panel, thereby ensuring the stability of the panel during use. In addition, in the present invention, the middle part of the panel bulges toward the side away from the frame.

[0028] In order to enable those skilled in the art to better understand the technical solution of the present invention, the present invention will be further described in detail below with reference to the accompanying drawings.

[0029] like Figure 1 and Figure 8 As shown, this embodiment provides a suspended soundproof wall panel, including a frame 1 and a plurality of panels 2. The width and height of the frame 1 are consistent with those of the wall. When installed, the frame 1 is installed on the wall and fits with the wall through fasteners such as expansion screws; the plurality of panels 2 are arranged in layers, the number of panels 2 in each layer is the same, and the surface of the panels 2 is coated with sound-absorbing materials such as foam or sponge; the first round rod 3 and the second round rod 4 are horizontally fixedly installed at the position corresponding to each layer of the panels 2 on the frame 1; the axes of each first round rod 3 and the second round rod 4 are located in the same vertical plane. The first round rod 3 corresponding to the same panel 2 is located above the second round rod 4. The middle part of the panel 2 protrudes toward the side away from the frame 1, and a hook 5 matching the corresponding first round rod 3 is installed on the panel 2; and a support claw 6 matching the corresponding second round rod 4 is also installed on the panel 2. The hook claw 5 and the support claw 6 are both semicircular, the opening of the hook claw 5 faces downward, and the opening of the support claw 6 faces the side away from the plate body 2; two hook claws 5 and two support claws 6 are installed on each plate body 2.

[0030] Specifically, after the installation of the suspended sound insulation wall panel is completed, the inner side of the hook claw 5 is in contact with the first round rod 3, and the panel body 2 is located on the side of the first round rod 3 away from the wall. Therefore, the panel body 2 tends to rotate toward the wall around the axis of the first round rod 3 under the action of gravity. However, since the inner side of the supporting claw 6 is in contact with the second round rod 4, that is, the second round rod 4 supports the panel body 2, the hook claw 5 and the supporting claw 6 as a whole, the panel body 2 can maintain a stable state. Only when the panel body 2 is subjected to an external force in the axial direction of the first round rod 3, the panel body 2 will rotate, and the supporting claw 6 will separate from the second round rod 4. In daily use, the cooperation between the hook claw 5 and the first round rod 3 prevents the panel body 2 from vibrating in the horizontal direction, and the cooperation between the supporting claw 6 and the second round rod 4 prevents the panel body 2 from vibrating in the vertical direction, thereby ensuring the stability of the panel body 2 in daily use.

[0031] like Figure 2 , Figure 3 and Figure 8 As shown, a first compensation bar 7 is horizontally fixedly installed on the top surface of the plate body 2, and a second compensation bar 8 is horizontally fixedly installed on the bottom surface of the plate body 2. The first compensation bar 7 and the second compensation bar 8 are both parallel to the first round rod 3, and the longitudinal sections of the first compensation bar 7 and the second compensation bar 8 are both semicircular and have the same shape and size; after the installation is completed, the arc surfaces of the first compensation bar 7 and the second compensation bar 8 on the two adjacent plate bodies 2 are in contact with each other, and the first compensation bar 7 is located on the side of the second compensation bar 8 close to the frame 1 (that is, close to the wall); the first compensation bar 7 and the second compensation bar 8 compensate for the gap between the two adjacent plate bodies 2, thereby preventing external sound from being transmitted into the room through the gap between the two adjacent plate bodies 2.

[0032] When the outside temperature is high, the plate body 2 will expand slightly, and the first compensation bar 7 on the lower plate body 2 and the second compensation bar 8 on the upper plate body 2 will generate an interaction force. Since the arc surfaces of the first compensation bar 7 and the second compensation bar 8 are in contact with each other, and the first compensation bar 7 is located on the side of the second compensation bar 8 close to the frame 1, the upper plate body 2 and the second compensation bar 8 and the first compensation bar 7 thereon will be subjected to a force in the direction of the room, while the lower plate body 2 and the first compensation bar 7 and the second compensation bar 8 thereon will be subjected to a force in the direction of the wall, thereby causing the upper plate body 2 and the second compensation bar 8 and the first compensation bar 7 thereon to rotate slightly around the upper first round rod 3, during which the hook claw 5 is always in contact with the first round rod 3, and the supporting claw 6 is separated from the second round rod 4, but the first compensation bar 7 and the second compensation bar 8 are always kept in contact with each other, so no gap will be generated between the two adjacent plate bodies 2 above and below; in this way, the plate body 2 in this embodiment will not generate a large mutual extrusion force after thermal expansion, thereby avoiding the occurrence of irreversible deformation of the plate body 2 due to extrusion.

[0033] It should be noted that in this embodiment, the middle part of the plate body 2 is designed to bulge toward the side away from the frame 1 (i.e., away from the wall), which has two effects. First, the sound waves transmitted from the wall into the room will rebound in an inclined direction after contacting the plate body 2, so that the sound waves within the same plate body 2 will contact each other, thereby promoting the elimination of sound waves and improving the sound insulation effect; second, after the plate body 2 expands due to heat, it will tend to a vertical state, making full use of the deformation characteristics of the plate body 2 itself to make the plate body 2 rotate around the first round rod 3, thereby reducing the extrusion force between the first compensation bar 7 and the second compensation bar 8, thereby reducing the damage to the first compensation bar 7 and the second compensation bar 8.

[0034] like Figure 1 , Figure 2 , Figure 4 , Figure 5 and Figure 7 As shown, the first round rod 3 is provided with a notch 301 at a position corresponding to each plate body 2, and the hook 5 can penetrate the first round rod 3 from the notch 301, and the hook 5 and the plate body 2 slide in a direction parallel to the axis of the first round rod 3; a first cable 9 is fixedly installed on the side of each hook 5 facing away from the other hook 5, and a second cable 10 is fixedly installed on the side of each hook 5 facing the other hook 5. The second cable 10 penetrates the plate body 2, and a cylindrical positioning pin 11 is fixedly installed at one end of the second cable 10, and a handle 12 is fixedly installed at the ends of the two positioning pins 11; the first cable 9 surrounds one side of the plate body 2 and a positioning column 13 that cooperates with the corresponding positioning pin 11 is fixedly installed at one end of the first cable 9.

[0035] Before installation, the two hooks 5 are located in the middle of the plate body 2. The operator holds the plate body 2 and brings the plate body 2 close to the frame 1, so that the two hooks 5 are translated to the position corresponding to the notch 301. Then the operator pulls the two first cables 9 at the same time, so that the two hooks 5 move away from each other. When the two hooks 5 move away from each other, the corresponding second cables 10 are also driven to move, thereby driving the positioning pin 11 and the handle 12 to move until one end of the positioning pin 11 fits with the surface of the plate body 2. In this state, the operator puts the positioning column 13 on the corresponding positioning pin 11, so that The locating pin 11 has a locating effect on the locating column 13, and the first cable 9 and the second cable 10 are both kept in a tensioned state; in this way, as long as the locating column 13 is sleeved on the locating pin 11, even if an external force acts on the handle 12 during use, the two hooks 5 will not move relative to the plate body 2, thereby ensuring stability during use; when the plate body 2 needs to be disassembled, the operator first removes the locating column 13 from the locating pin 11, and then pulls the handle 12 to synchronously pull the two hooks 5 to the position corresponding to the notch 301, and then translates the plate body 2.

[0036] In summary, this embodiment ingeniously utilizes the first cable 9 and the second cable 10 to achieve convenient control of the hook 5, and utilizes the cooperation of the positioning column 13 and the positioning pin 11 to achieve positioning of the hook 5 during use, thereby ensuring the stability of the plate body 2 in use.

[0037] In actual use, if the radius of the inner arc surface of the hook 5 is exactly the same as the radius of the first round rod 3, the hook 5 will generate a large friction force with the first round rod 3 when it moves horizontally from the notch 301 to both sides, and even interfere with each other due to inevitable precision errors; in view of this situation, this embodiment is designed as follows.

[0038] like Figure 2 and Figure 6 As shown, the radius of the inner arc surface of the hook claw 5 is greater than the radius of the first round rod 3, and a plurality of accommodating grooves 501 are evenly opened on the inner arc surface of the hook claw 5, and a ball 14 is movably installed in each accommodating groove 501; a strip groove 502 connecting the accommodating grooves 501 is opened at a position corresponding to each accommodating groove 501 on the side wall of the hook claw 5; a semicircular stopper 15 is fixedly installed at a position corresponding to each hook claw 5 on the first round rod 3, and an insert strip 16 is fixedly installed at a position corresponding to the strip groove 502 on the stopper 15.

[0039] Specifically, when the two hook claws 5 move horizontally from the notch 301 to both sides, after the hook claws 5 leave the notch 301, since the radius of the inner arc surface of the hook claw 5 is greater than the radius of the first round rod 3, the hook claw 5 will not form friction and interference with the edge of the notch 301; the hook claw 5 gradually approaches the stopper 15 during the process of moving to the predetermined position, and the insertion strip 16 on the stopper 15 is inserted into the corresponding strip groove 502 and contacts with the corresponding ball 14, and finally pushes the ball 14 to Figure 6 In the state shown, the ball 14 fits with the notch of the accommodating groove 501, and each ball 14 fits with the circumferential surface of the first round rod 3; thus, during use, the inner side of the hook 5 does not directly contact the first round rod 3, but contacts the first round rod 3 through the ball 14. When the hook 5 rotates relative to the first round rod 3, the friction force is greatly reduced.

[0040] The above description is only by way of illustration of certain exemplary embodiments of the present invention. It is undoubted that those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the above drawings and descriptions are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
