Description

Technical Field

[0001] The present invention belongs to the technical field of roof structures, and particularly relates to a sound insulation ceiling structure. Background Art

[0002] A ceiling refers to the decoration of the ceiling of a house. It can not only beautify the indoor environment, but also play roles such as heat insulation, heat preservation, and sound insulation by selecting ceiling materials with corresponding functions. Currently, the common sound insulation ceiling usually fixes the keel to the roof using hanging hooks. After setting a sealing strip around the sound insulation board, multiple sound insulation boards are installed on the keel through screws. Eventually, a sound insulation cavity is formed above the sound insulation board. Because the sound insulation board contains sound insulation materials such as sound insulation felt inside, it can effectively isolate the transmission of sound. The defect of this ceiling structure is that during installation, it is necessary to frequently use screws and rivets to connect multiple components, making the installation of the ceiling structure time-consuming and laborious. Moreover, when disassembling the sound insulation board, removing the screws and rivets is likely to damage the sound insulation board.

[0003] The invention patent with the publication number CN111764568B discloses a household sound insulation ceiling for the roof and its installation method, which realizes the mutual snap-in installation of the light steel keel, load-bearing keel, and sound insulation board, and does not require the use of screws or rivets to install the sound insulation board, improving the convenience of installation and disassembly. However, this solution does not consider the sealing between adjacent sound insulation boards. Existing sound insulation boards usually have elastic sealing strips pre-set around them and then are installed. In this solution, since the sound insulation board and the light steel keel are snap-in installed through a T-shaped block, the sound insulation board can only be pushed horizontally during installation. When there are sound insulation rubber strips on the periphery of the sound insulation board, during the process of pushing and installing the sound insulation board, the sealing rubber strips between adjacent sound insulation boards are in mutual contact, with a relatively large frictional force, which makes it difficult to push the sound insulation board to the preset installation position, affecting the installation efficiency. Therefore, it is necessary to make improvements. Summary of the Invention

[0004] To solve the above-mentioned defects of the prior art, the present application provides a sound insulation ceiling structure. Compared with the complete use of screws or rivets to install the sound insulation ceiling, this solution is convenient for installation and disassembly, and at the same time can achieve the sealing between the sound insulation boards.

[0005] To achieve the above purpose, the present invention adopts the following technologies:

[0006] A sound insulation ceiling structure, comprising:

[0007] A plurality of suspension components, arranged in a rectangular array, and a sliding sleeve is connected to the bottom of each suspension component;

[0008] A plurality of connection components, each including an I-shaped block and a set of slide rails. The bottom of the I-shaped block is slidably connected between the set of slide rails through a slider. The tops of the plurality of I-shaped blocks are respectively slidably connected to the plurality of sliding sleeves, and a first stop block is provided at one end of each slide rail;

[0009] Multiple sound insulation panels, the tops of which are respectively connected to multiple sets of sliding rails, and the sliding direction of the sliders is parallel to the length direction of the sound insulation panels. When the sliders abut against the first stoppers and the I-shaped blocks completely enter the sliding sleeves, the suspension assemblies are directly above the centers of the sound insulation panels. On both sides of the tops of the sound insulation panels, first hinge assemblies and second hinge assemblies are respectively provided. Adjacent sound insulation panels in each column of sound insulation panels are hinged through the first hinge assemblies and the second hinge assemblies. First sound insulation rubber strips matching the widths of the sound insulation panels are provided on both sides of the sound insulation panels. When two mutually hinged sound insulation panels rotate to the horizontal state, the corresponding two first sound insulation rubber strips abut against each other and are in a compressed state. Second sound insulation rubber strips are provided between each row of sound insulation panels, and the lengths of the second sound insulation rubber strips match the total lengths of each row of sound insulation panels. When the second sound insulation rubber strips are in the natural state, the widths of the second sound insulation rubber strips are greater than the distances between adjacent two rows of sound insulation panels.

[0010] Further, the bottom of the suspension assembly is rotatably connected to a rotating ring, the rotating ring is connected to the top of the sliding sleeve, the I-shaped block is rotatably connected to the slider, and a second stopper is provided at one end of the sliding sleeve.

[0011] Further, a first through hole is provided on the circumferential side of the rotating ring for connecting a pin, and a second through hole matching the first through hole is provided on the circumferential side of the suspension assembly. When the length direction of the I-shaped block rotates to be parallel to the sliding direction of the slider, the first through hole is aligned with the second through hole.

[0012] Further, the suspension assembly includes a vertical frame and a connecting rod. A third through hole is provided at the bottom of the vertical frame, and the diameter of the third through hole is greater than the diameter of the connecting rod. A buffer block is provided above the third through hole, and the connecting rod is slidably connected to the buffer block in the vertical direction. A limiting ring is provided at the top of the connecting rod, a first spring is provided between the limiting ring and the buffer block, the bottom of the connecting rod passes through the third through hole and is rotatably connected to the rotating ring, the second through hole is provided on the circumferential side of the connecting rod, and an inverted fixing screw is connected to the top of the vertical frame for connecting to the roof.

[0013] Further, horizontal fixing rods are spaced below each column of vertical frames. Fourth through holes are arrayed along the length direction on the fixing rods, the connecting rods pass through the fourth through holes, vertical grooves are provided on the circumferential sides of the fourth through holes, limiting blocks matching the vertical grooves are provided on the circumferential sides of the connecting rods, the limiting blocks are below the vertical frames, and fixing pieces are provided at both ends of the fixing rods, and fixing holes are provided on the fixing pieces.

[0014] Further, a retaining ring is provided on the circumferential side of the connecting rod. When the limiting blocks completely pass through the bottoms of the vertical grooves, the retaining ring abuts against the tops of the fixing rods.

[0015] Further, a plurality of third stoppers are arrayed at the bottom of the fixing rod. When the limiting blocks rotate to abut against the third stoppers on one side, the limiting blocks are perpendicular to the vertical grooves, and the length direction of the sliding sleeve is parallel to the sliding direction of the slider.

[0016] Furthermore, a rectangular baffle is provided at the bottom of the peripheral side of the sound insulation board. The four side surfaces of the rectangular baffle protrude from the four side surfaces of the sound insulation board respectively. When two mutually hinged sound insulation boards are rotated to the horizontal state, the corresponding two rectangular baffles are in contact with each other. When the rectangular baffles on adjacent columns of sound insulation boards are in contact with each other, the second sound insulation strip is in a compressed state.

[0017] Furthermore, the first hinge assembly includes a pair of first connection pieces fixedly spaced on one side of the top of the sound insulation board. One end of each first connection piece is provided with a hinge hole, and the hinge hole is located outside the sound insulation board and has a first preset distance from one side of the sound insulation board in the horizontal direction. The second hinge assembly includes a pair of fixed seats fixedly spaced on the other side of the top of the sound insulation board. A sliding rod is arranged along the length direction of the sound insulation board in each of them. A second connection piece is slidably connected to each sliding rod. A connecting shaft that is height-matched with the hinge hole is arranged on the outside of each second connection piece. The connecting shaft is located outside the sound insulation board and has a first preset distance from the other side of the sound insulation board in the horizontal direction. A second spring is sleeved on the sliding rod, and one end of the second spring abuts against the inner side of the second connection piece. When the second connection piece abuts against the outer end of the fixed seat, the second spring is in a natural state, and the distance between the outer sides of the pair of second connection pieces matches the distance between the inner sides of the pair of first fixed pieces.

[0018] The beneficial effects of the present invention are as follows:

[0019] 1. Compared with the ceiling structure installed completely using screws or rivets, this solution is convenient for installation and disassembly, and at the same time, rapid sealing between the sound insulation boards can be achieved, solving the problem that when installing adjacent sound insulation boards, it is necessary to horizontally push the sound insulation boards, and the mutual friction between adjacent sound insulation strips is relatively large, making the installation difficult.

[0020] 2. After the sound insulation board is installed and the rotating ring and the sliding sleeve are rotated 180 degrees, the second stop block on the sliding sleeve will block the I-shaped block from moving away from the second sound insulation strip, and the sliding block below the I-shaped block will block the first stop block from moving away from the second sound insulation strip. In this way, the elastic force of the second sound insulation strip can be overcome, preventing the installed sound insulation board from being pushed open.

[0021] 3. The sound insulation board is installed below the connecting rod. The connecting rod is not rigidly connected to the vertical frame and does not directly contact the vertical frame. By using the buffering of the spring and the buffer block, the sound bridge with the vertical frame and the ceiling can be cut off, reducing noise transmission. BRIEF DESCRIPTION OF THE DRAWINGS

Detailed implementation manners

[0034] To make the objectives, technical solutions and advantages of the embodiments of the present invention clearer, the following will describe the embodiments of the present invention in detail with reference to the accompanying drawings. However, the embodiments described herein are only a part of the embodiments of the present invention, rather than all of the embodiments.

[0035] An embodiment of the present application provides a sound insulation ceiling structure, as Figures 1-11 shown, including a suspension assembly 1, a connection assembly, a sound insulation board 4, etc.

[0036] Specifically, there are multiple suspension assemblies 1, which are arranged in a rectangular array, and a sliding sleeve 2 is connected to the bottom of each suspension assembly 1; the number of connection assemblies is the same as that of the suspension assemblies 1, and each includes an I-shaped block 3 and a set of slide rails 301. The bottom of the I-shaped block 3 is slidably connected between a set of slide rails 301 through a slider 302. The tops of multiple I-shaped blocks 3 are respectively slidably connected to multiple sliding sleeves 2. A first stop block 3011 is provided at one end of each slide rail 301 for blocking the slider 302; the number of sound insulation boards 4 is also the same as that of the suspension assemblies 1. The tops of multiple sound insulation boards 4 are respectively connected to multiple sets of slide rails 301. The sliding direction of the slider 302 is parallel to the length direction of the sound insulation board 4. When the slider 302 abuts against the first stop block 3011 and the I-shaped block 3 completely enters the sliding sleeve 2, the suspension assembly 1 is directly above the center of the sound insulation board 4. First hinge assemblies 401 and second hinge assemblies 402 are respectively provided on both sides of the top of the sound insulation board 4. Adjacent sound insulation boards 4 in each column of sound insulation boards 4 are hinged through the first hinge assembly 401 and the second hinge assembly 402. First sound insulation rubber strips 5 matching the width of the sound insulation board 4 are provided on both sides of the sound insulation board 4. When two mutually hinged sound insulation boards 4 are rotated to a horizontal state, the corresponding two first sound insulation rubber strips 5 abut against each other and are in a compressed state. Second sound insulation rubber strips 6 are provided between each row of sound insulation boards 4. The length of the second sound insulation rubber strip 6 matches the total length of each row of sound insulation boards 4. When the second sound insulation rubber strip 6 is in a natural state, the width of the second sound insulation rubber strip 6 is greater than the distance between adjacent two rows of sound insulation boards 4. Specifically, the total length of each row of sound insulation boards 4 refers to the distance between the outsides of the two outermost sound insulation boards 4 in each row of sound insulation boards 4.

[0037] In actual use, a plurality of hanging components 1 are installed on the roof ceiling in a rectangular array. Then, a row of sound insulation boards 4 is installed below a row of hanging components 1 on the side close to the ceiling. The specific installation method is as follows: First, push the I-shaped block 3 slidably connected to the outermost sound insulation board 4 in a row of sound insulation boards 4 into the corresponding sliding sleeve 2. Then, connect the second hinge assembly 402 of the next sound insulation board 4 to the first hinge assembly 401 of the sound insulation board 4 that has been installed first. Then, rotate the later-installed sound insulation board 4 downward to the horizontal state, so that the two first sound insulation rubber strips 5 between the two sound insulation boards 4 are in a mutually pressed state, closing the gap between the two sound insulation boards 4. Then, push the I-shaped block 3 slidably connected to the later-installed sound insulation board 4 into the corresponding sliding sleeve 2 above it to fix the sound insulation board 4 and prevent the sound insulation board 4 from rotating upward under the thrust of the first sound insulation rubber strip 5. Then, repeat the above steps to complete the installation of a row of sound insulation boards 4. When installing the second row of sound insulation boards 4, first install the second sound insulation rubber strip 6 on the side of the previous row of sound insulation boards 4 away from the wall, so that the second sound insulation rubber strip 6 covers the previous row of sound insulation boards 4. Then, repeat the above steps to install the subsequent rows of sound insulation boards 4 to complete the installation of all sound insulation boards 4. Since the distance between two adjacent rows of sound insulation boards 4 after installation is less than the width of the second sound insulation rubber strip 6 in the natural state, the second sound insulation rubber strip 6 will be squeezed, cooperating with the first sound insulation rubber strip 5 to improve the sealing effect and thus improve the sound insulation effect.

[0038] Specifically, refer to Figures 4-7, the first hinge assembly 401 includes a pair of first connecting pieces 4011, the first connecting pieces 4011 are fixedly spaced on one side of the top of the sound insulation board 4, one end of the first connecting piece 4011 is provided with a hinge hole 4012, the hinge hole 4012 is located outside the sound insulation board 4, and the hinge hole 4012 has a first preset distance from one side of the sound insulation board 4 in the horizontal direction. The second hinge assembly 402 includes a pair of fixed seats 4021 and a pair of second connecting pieces 4022. The pair of fixed seats 4021 are fixedly spaced on the other side of the top of the sound insulation board 4. A sliding rod 4023 is arranged in each of the fixed seats 4021 along the length direction of the sound insulation board 4. The pair of second connecting pieces 4022 are respectively slidably connected to the two sliding rods 4023. A connecting shaft 4024 that is height-matched with the hinge hole 4012 is arranged on the outside of each of the pair of second connecting pieces 4022. The connecting shaft 4024 is located outside the sound insulation board 4, and the connecting shaft 4024 has a first preset distance from the other side of the sound insulation board 4 in the horizontal direction. A second spring 4025 is sleeved on the sliding rod 4023. One end of the second spring 4025 abuts against the inner side of the second connecting piece 4022. When the second connecting piece 4022 abuts against the outer end of the fixed seat 4021, the second spring 4025 is in a natural state, and the distance between the outside of the pair of second connecting pieces 4022 matches the distance between the inner sides of the pair of first connecting pieces 4011. When connecting the first hinge assembly 401 and the second hinge assembly 402, first push the second connecting piece 4022 inward so that the distance between the outside of the connecting shafts 4024 on the pair of second connecting pieces 4022 is less than the distance between the inner sides of the pair of first connecting pieces 4011, then align the pair of connecting shafts 4024 with the hinge holes 4012 on the pair of first connecting pieces 4011, and finally cancel the pushing force on the second connecting piece 4022, and the connecting shaft 4024 will enter the hinge hole 4012 under the pushing force of the second spring 4025.

[0039] Preferably, referring to Figures 5-8 , the bottom of the suspension assembly 1 is rotatably connected to a rotating ring 7, the rotating ring 7 is connected to the top of the sliding sleeve 2, the I-shaped block 3 is rotatably connected to the slider 302, and a second stopper 201 is arranged at one end of the sliding sleeve 2. When installing the first row of sound insulation boards 4 and then installing subsequent rows of sound insulation boards 4, the sound insulation board 4 can be first pushed to press the second sound insulation strip 6, so that the sound insulation board 4 is aligned with the upper suspension assembly 1, then the I-shaped block 3 is pushed to abut against the second stopper 201, and at the same time the slider 302 is made to abut against the first stopper 3011, and then the rotating ring 7 and the sliding sleeve 2 are rotated 180 degrees, as shown in Figure 7As shown in the figure, at this time, the second stopper 201 on the sliding sleeve 2 will block the I-shaped block 3 from moving away from the second sound insulation strip 6, and the slider 302 under the I-shaped block 3 will block the first stopper 3011 from moving away from the second sound insulation strip 6. By this way, the elastic force of the second sound insulation strip 6 can be overcome, and the installed sound insulation board 4 can be prevented from being pushed away. Specifically, a first through hole 701 is provided on the circumferential side of the rotating ring 7 for connecting the pin 8. A second through hole 1021 matching the first through hole 701 is provided on the circumferential side of the suspension assembly 1. When the I-shaped block 3 rotates to a length direction parallel to the sliding direction of the slider 302, the first through hole 701 is aligned with the second through hole 1021. After rotating the rotating ring 7 and the sliding sleeve 2 by 180 degrees, the pin 8 is inserted into the rotating first through hole 701 and the second through hole 1021, which can prevent the rotating ring 7 from rotating and improve the stability of the installed sound insulation board 4.

[0040] Preferably, referring to Figures 9-11 , the suspension assembly 1 includes a vertical frame 101 and a connecting rod 102. A third through hole 1011 is provided at the bottom of the vertical frame 101. The diameter of the third through hole 1011 is larger than the diameter of the connecting rod 102. A buffer block 103 is provided above the third through hole 1011. The connecting rod 102 is slidably connected to the buffer block 103 in the vertical direction. A limit ring 1022 is provided at the top of the connecting rod 102. A first spring 104 is provided between the limit ring 1022 and the buffer block 103. The bottom of the connecting rod 102 passes through the third through hole 1011 and is rotatably connected to the rotating ring 7. The second through hole 1021 is provided on the circumferential side of the connecting rod 102. The top of the vertical frame 101 is connected with an inverted fixing screw 105 for connecting to the roof. When installing the suspension assembly 1, the vertical frame 101 is fixed by connecting the fixing screw 105 to the ceiling. Since the sound insulation board 4 is installed below the connecting rod 102, the connecting rod 102 is not rigidly connected to the vertical frame 101 and does not directly contact the vertical frame 101. By using the buffering of the spring and the buffer block 103, the sound bridge between the vertical frame 101 and the ceiling can be cut off, reducing noise transmission.

[0041] Specifically, referring to Figures 9-11, a horizontal fixing rod 9 is provided at intervals below each vertical frame 101. Fourth through holes 901 are arranged in an array along the length direction on the fixing rod 9. A connecting rod 102 is inserted into the fourth through holes 901. Vertical grooves 902 are formed on the peripheries of the fourth through holes 901. A limiting block 1023 matching the vertical grooves 902 is arranged on the periphery of the connecting rod 102. The limiting block 1023 is located below the vertical frame 101. Fixing pieces 903 are arranged at both ends of the fixing rod 9, and fixing holes 9031 are formed in the fixing pieces 903. During actual installation, multiple connecting rods 102 of multiple hanging components 1 in a column can be first inserted into multiple fourth through holes 901 on the corresponding fixing rod 9, and then the connecting rod 102 is rotated by 90 degrees to lift the hanging component 1. In this way, the fixing rod 9 will not break away from the connecting rod 102. Then, multiple hanging components 1 are installed on the ceiling, and the installation of a column of hanging components 1 is completed. By this method, it is not necessary to manually measure the distance between adjacent hanging components 1 during the installation of the hanging components 1, which improves the installation accuracy. Moreover, the fixing rod 9 can be connected to the wall through the fixing holes 9031 on the fixing pieces 903 at both ends of the connecting rod 102, which improves the stability of the fixing rod 9 and further improves the stability of the hanging component 1.

[0042] More specifically, refer to Figures 9-11 , a plurality of third stop blocks 904 are arranged in an array at the bottom of the fixing rod 9. When the limiting block 1023 rotates to one side and abuts against the third stop block 904, the limiting block 1023 is perpendicular to the vertical groove 902, and the length direction of the sliding sleeve 2 is parallel to the sliding direction of the slider 302. When installing the hanging component 1 on the ceiling, first fixedly connect the fixing rod 9 to the wall, and then rotate the limiting block 1023 until one side of it abuts against the third stop block 904, and the alignment of the hanging component 1 can be quickly completed, improving the installation efficiency.

[0043] Preferably, refer to Figures 9-11 A retaining ring 1024 is arranged on the periphery of the connecting rod 102. When the limiting block 1023 completely passes through the bottom of the vertical groove 902, the retaining ring 1024 abuts against the top of the fixing rod 9. Specifically, the retaining ring 1024 can be provided with an elastic gasket to improve the buffering ability of the connecting rod 102 when it is vibrated. When installing the hanging component 1, the fixing rod 9 can be directly lifted, and the retaining ring 1024 will block the downward movement of the connecting rod 102, preventing the connecting rod 102 from moving up and down, and further improving the installation efficiency.

[0044] Preferably, refer to Figure 6, a rectangular baffle 403 is provided at the bottom of the four sides of the sound insulation board 4. The four sides of the rectangular baffle 403 protrude from the four sides of the sound insulation board 4 respectively. When two mutually hinged sound insulation boards 4 rotate to the horizontal state, the corresponding two rectangular baffles 403 are in contact with each other. In this way, the maximum limit of the downward rotation of the sound insulation board 4 can be restricted, and there is no need for manual judgment of the rotation angle of the sound insulation board 4. When the rectangular baffles 403 on two adjacent columns of sound insulation boards 4 are in contact with each other, the second sound insulation strip 6 is in a compressed state, which is convenient for the sound insulation board 4 to be aligned with the upper suspension assembly 1 and the sliding sleeve 2. Moreover, the rectangular baffle 403 can block the first sound insulation strip 5 and the second sound insulation strip 6 to prevent them from detaching from the sound insulation board 4. At the same time, it is avoided that after the first sound insulation strip 5 and the second sound insulation strip 6 are deformed due to extrusion, their bottoms protrude from the bottom of the sound insulation board 4, affecting the beauty of the ceiling.

[0045] The above are only the preferred embodiments of the present invention, and do not represent that they are the only ones or limit the present invention. Those skilled in the art should understand that various changes or equivalent replacements made to the present invention without departing from the scope of the present invention all fall within the scope of protection of the present invention.
