Description

Technical Field

[0001] This utility model relates to the field of light steel keel ceiling technology, and in particular to a sound-absorbing and vibration-damping ceiling structure. Background Technology

[0002] Light steel keel is mainly made of galvanized steel sheet or thin-walled cold-formed thin-walled steel. It has the characteristics of high strength and light weight. Compared with traditional wooden keel, it has the advantages of not being easily deformed or cracked, being able to withstand greater loads, and having a long service life. Light steel keel comes in various specifications, such as main keel, secondary keel, and cross bracing keel. According to the keel cross section, it can be divided into U-shaped keel, C-shaped keel, L-shaped keel, etc. After the light steel keel is assembled into a ceiling frame, gypsum board is covered to form a ceiling structure. Ordinary ceiling structures have poor sound insulation.

[0003] Chinese Patent Publication No. CN219528121U discloses a sound-absorbing and vibration-damping ceiling structure, comprising: a hanger, a main keel, a secondary keel, a sound-absorbing panel, and a vibration-damping pad. The main keel is horizontally positioned at the bottom of the hanger, the secondary keel is horizontally positioned below the main keel, the vibration-damping pad is positioned below the secondary keel, and the sound-absorbing panel is positioned below the vibration-damping pad. The bottom surface of the sound-absorbing panel has several recessed mounting holes spaced apart along the length of the secondary keel. Countersunk screws are installed in the mounting holes, penetrating the vibration-damping pad and extending into the secondary keel. Nuts corresponding to the countersunk screws are installed in the secondary keel, and vibration-damping washers are installed at the bottom of the nuts. This design ensures sound absorption and improves vibration damping performance.

[0004] The above-mentioned technology improves the sound absorption and vibration reduction effect of the ceiling by installing vibration damping pads and sound-absorbing panels on the sound-absorbing keel. However, thicker vibration damping pads and sound-absorbing panels will cause the light steel keel to bear a heavier load, making it difficult to ensure the stability of the ceiling structure. On the other hand, thinner vibration damping pads and sound-absorbing panels cannot achieve the ideal sound absorption and vibration reduction effect. Therefore, this utility model discloses a sound-absorbing and vibration-reducing ceiling structure to solve the above problems. Utility Model Content

[0005] The purpose of this utility model is to provide a sound-absorbing and vibration-damping ceiling structure to solve the technical problems mentioned in the background art. Traditional ceiling structures use damping pads and sound-absorbing panels for sound absorption and vibration reduction, but thicker damping pads and sound-absorbing panels will cause the light steel keel to bear a heavy load, making it difficult to ensure the stability of the ceiling structure, while thinner damping pads and sound-absorbing panels cannot achieve the ideal sound absorption and vibration reduction effect.

[0006] To achieve the above objectives, the present invention provides the following solution to the aforementioned technical problems: a sound-absorbing and vibration-damping ceiling structure, comprising suspension rods, main keel, secondary keel, sound-absorbing wedges, connecting components, and gypsum board. A main keel is installed between the bottom ends of the suspension rods in the same row. Multiple secondary keels are arranged below the main keel. At least two connecting components are installed at the bottom of the main keel. The bottom end of each connecting component passes through a sound-absorbing wedge and connects to an adjacent secondary keel. All secondary keels are connected to the gypsum board.

[0007] As a further embodiment of this utility model, the main keel and the secondary keel are perpendicular to each other.

[0008] As a further embodiment of this utility model, both the main keel and the secondary keel are C-shaped keels.

[0009] As a further embodiment of this utility model, the connecting assembly includes a bolt located in the groove of the main keel, and the bottom end of the bolt passes through the lower groove wall of the main keel and the sound-absorbing wedge and is threaded with a washer.

[0010] As a further embodiment of this utility model, the sound-absorbing wedge includes a sound-absorbing part and a mounting part, the sound-absorbing part and the mounting part are spaced apart, the side of the sound-absorbing part away from the main keel has a wave-shaped structure, and the mounting part has mounting holes corresponding to bolts.

[0011] As a further embodiment of this utility model, the bottom end of the suspension rod penetrates the upper groove wall of the main keel, and the outer side of the suspension rod and both sides of the upper groove wall of the main keel are threaded with a first nut.

[0012] As a further embodiment of this utility model, the connecting assembly further includes two second nuts that are threadedly connected to the bottom end of the bolt, and the upper groove wall of the secondary keel is sleeved on the outer side of the bolt, with the upper groove wall of the secondary keel located between the two second nuts.

[0013] As a further embodiment of this utility model, the lower groove walls of the secondary keel are all located in the same plane, and the gypsum board is fixed to the lower groove wall of the secondary keel by self-tapping screws.

[0014] Compared with the prior art, the beneficial effects of this utility model are:

[0015] This utility model discloses a sound-absorbing and vibration-damping ceiling structure. Sound-absorbing wedges are added to the ceiling structure. The wave-shaped structure of the sound-absorbing wedges can scatter and guide sound waves. When sound waves encounter the wave-shaped structure, they are dispersed into multiple directions, thereby reducing the concentrated reflection of sound waves in a specific direction. Combined with the material properties of the sound-absorbing wedges themselves, they can effectively absorb excess sound waves, avoid sound reverberation and interference, and achieve better sound absorption effect while saving the weight and amount of sound-absorbing material.

[0016] This utility model discloses a sound-absorbing and vibration-damping ceiling structure. The sound-absorbing wedge is installed between the main keel and the secondary keel through a connecting component, which can form an integral structure with the ceiling. When subjected to external impact or vibration, the sound-absorbing wedge and the keel structure share the force, which can disperse stress, reduce the transmission of vibration, effectively reduce the damage of vibration to the ceiling structure, and extend the service life of the ceiling.

[0023] 1. Hanging rod; 2. Main keel; 3. Secondary keel; 4. Sound-absorbing wedge; 5. Connecting assembly; 6. Gypsum board; 11. First nut; 31. Self-tapping screw; 41. Sound-absorbing part; 42. Mounting part; 43. Mounting hole; 51. Bolt; 52. Washer; 53. Second nut. Detailed Implementation

[0024] The present invention will be further described below with reference to the embodiments.

[0025] Please see Figure 1-4 This utility model provides a sound-absorbing and vibration-damping ceiling structure, including a suspension rod 1, a main keel 2, a secondary keel 3, a sound-absorbing wedge 4, a connecting component 5, and a gypsum board 6. The secondary keels 3 are all connected to the gypsum board 6, and the lower groove walls of the secondary keels 3 are all located in the same plane. The gypsum board 6 is fixed to the lower groove wall of the secondary keel 3 by self-tapping screws 31.

[0026] Specifically, inconsistent heights of the secondary keel 3 can cause problems such as tilting and warping of the plasterboard 6. During installation, the construction workers need to lift the plasterboard 6 to fit against the lower groove wall of the secondary keel 3. Then, at a certain interval, self-tapping screws 31 are driven into the contact area between the plasterboard 6 and the secondary keel 3. The self-tapping screws 31 will pass through the plasterboard 6 and screw into the lower groove wall of the secondary keel 3, thereby firmly fixing the plasterboard 6 to the secondary keel 3. It is worth noting that when driving in the self-tapping screws 31, it is necessary to ensure that the screw head of the self-tapping screw 31 can be embedded inside the plasterboard 6 so that latex paint can be applied to the plasterboard 6 later.

[0027] Specifically, multiple sound-absorbing wedges 4 are located in the same plane. Adhesive is applied to the sides of the sound-absorbing wedges 4, which can bond adjacent sound-absorbing wedges 4 into a whole structure, thereby forming a dense and breathable sound insulation layer, which can ensure the sound insulation effect.

[0028] Furthermore, both the main keel 2 and the secondary keel 3 are C-shaped keels;

[0029] Specifically, the main keel 2 and the secondary keel 3 are made of galvanized steel sheet or aluminum alloy. The C-shaped keel has a "U" shaped cross section, which can maintain stable performance for a long time and has the advantages of light weight and high strength.

[0030] Furthermore, the bottom end of the suspension rod 1 penetrates the upper groove wall of the main keel 2, and the outer side of the suspension rod 1 and both sides of the upper groove wall of the main keel 2 are threaded with a first nut 11.

[0031] Specifically, during installation, first screw one first nut 11 onto the hanger 1 so that it abuts against the upper groove wall of the main keel 2. Then, screw the other first nut 11 onto the bottom end of the hanger 1 so that the upper groove wall of the main keel 2 is clamped between the two first nuts 11. By screwing the two first nuts 11, the height of the two can be adjusted, thereby adjusting the height of the main keel 2, which can compensate for the height error of the hanger 1 during installation and keep the main keel 2 on the same plane.

[0032] Furthermore, a main keel 2 is installed between the bottom ends of the suspension rods 1 in the same row, and a plurality of secondary keels 3 are provided below the main keel 2, with the main keel 2 and the secondary keels 3 being perpendicular to each other;

[0033] Specifically, the perpendicular arrangement of the main keel 2 and the secondary keel 3 can form a stable grid structure, which can effectively distribute and bear the loads from all directions, avoid local overload, and thus improve the stability of the entire ceiling system.

[0034] Furthermore, at least two connecting components 5 are installed at the bottom of the main keel 2. The bottom end of the connecting component 5 passes through the sound-absorbing wedge 4 and is connected to the adjacent secondary keel 3. The connecting component 5 includes a bolt 51 located in the groove of the main keel 2. The bottom end of the bolt 51 passes through the lower groove wall of the main keel 2 and the sound-absorbing wedge 4 and is threaded with a washer 52.

[0035] Specifically, during installation, a through hole is drilled in the lower groove wall of the main keel 2 using a drill gun. After the bottom end of the bolt 51 passes through the through hole in the lower groove wall of the main keel 2, the mounting hole 43 of the sound-absorbing wedge 4 is aligned with the bolt 51, so that the bolt 51 passes through the mounting hole 43 of the sound-absorbing wedge 4. A washer 52 is threaded onto the bottom end of the bolt 51. By tightening the washer 52, the sound-absorbing wedge 4 is clamped between the main keel 2 and the washer 52, ensuring that the sound-absorbing wedge 4 is firmly fixed on the main keel 2. The main keel 2 is wider, has a thicker wall, and is stronger, so the weight of the sound-absorbing wedge 4 is more stable on the main keel 2.

[0036] Furthermore, the connecting assembly 5 also includes two second nuts 53 that are threaded to the bottom end of the bolt 51. The upper groove wall of the secondary keel 3 is sleeved on the outside of the bolt 51, and the upper groove wall of the secondary keel 3 is located between the two second nuts 53.

[0037] Specifically, during installation, first screw a second nut 53 into the bottom of bolt 51, align the upper groove wall of the secondary keel 3 with the bolt 51, and then screw another second nut 53 into the bottom of bolt 51, so that the upper groove wall of the secondary keel 3 is clamped between the two second nuts 53. By screwing the two second nuts 53, the height of the secondary keel 3 can be adjusted, thereby overcoming the height error during the installation of the suspension rod 1 and keeping the secondary keels 3 all on the same plane.

[0038] Furthermore, the sound-absorbing wedge 4 includes a sound-absorbing part 41 and a mounting part 42, the sound-absorbing part 41 and the mounting part 42 are spaced apart, the side of the sound-absorbing part 41 away from the main keel 2 has a wave-shaped structure, and the mounting part 42 has a mounting hole 43 corresponding to the bolt 51.

[0039] Specifically, when sound waves encounter the wave-shaped structure of the sound-absorbing wedge 4, they are dispersed into multiple directions, thereby reducing the concentrated reflection of sound waves in a specific direction and increasing the propagation path of sound waves on the surface of the sound-absorbing material. This allows sound waves to have more opportunities to be absorbed during propagation. The sound-absorbing wedge 4 is made of polyester fiber, glass fiber, mineral wool, or foam plastic, which can effectively absorb excess sound waves and avoid sound reverberation and interference. It is worth noting that the width of the mounting part 42 is no more than 2 cm to prevent poor sound absorption in the central area of ​​the sound-absorbing wedge 4, which would lead to a deterioration in sound insulation. At the same time, the mounting part 42 and the sound-absorbing parts 41 on both sides can also form a trough structure, which can play a sound absorption role. On the other hand, since the sound-absorbing wedge 4 is made of flexible material, it can disperse and absorb vibration energy through its own deformation when subjected to external impact or vibration, which can effectively reduce the damage of vibration to the ceiling structure.

[0040] Working principle: The following construction steps are included in the use:

[0041] Step 1: Drill holes in the top surface and drive the suspension rod 1 with an expansion nail at the top into the holes;

[0042] Step 2: Make a through hole in the upper groove wall of the main keel 2, align the through hole with the suspension rod 1 and insert it, so that the upper groove wall of the main keel 2 abuts against the first nut 11 above it. Then, screw a new first nut 11 into the bottom end of the suspension rod 1 so that the upper groove wall of the main keel 2 can be clamped between the two first nuts 11.

[0043] Step 3: Make a through hole in the lower groove wall of the main keel 2, insert the bolt 51 into the through hole from top to top, and align the mounting hole 43 with the bottom end of the bolt 51. Then, screw the washer 52 into the bottom end of the bolt 51 so that the sound-absorbing wedge 4 can be clamped between the main keel 2 and the washer 52.

[0044] Step 4: Make a through hole in the upper groove wall of the secondary keel 3. First, screw a second nut 53 into the bottom of the bolt 51. Then, align the through hole with the bolt 51 and insert it. After that, screw a second nut 53 into the bottom of the bolt 51 so that the upper groove wall of the secondary keel 3 can be clamped between the two second nuts 53.

[0045] Step 5: Tighten the second nut 53 and adjust the height of the secondary keel 3 on each bolt 51 so that the lower groove wall of the secondary keel 3 is in the same plane.

[0046] Step 6: Place the plasterboard 6 against the lower groove wall of the secondary keel 3, and drive self-tapping screws 31 into the contact area between the plasterboard 6 and the secondary keel 3 to ensure that the plasterboard 6 is fully fixed.
