Description

Technical Field

[0001] The utility model relates to the technical field of building construction, in particular to a sound-absorbing and sound-insulating shock-absorbing ceiling structure. Background Art

[0002] Traditional suspended ceiling rods fail to fully consider acoustics, particularly the sound absorption, insulation, and vibration reduction properties of the suspended ceiling. In traditional construction, existing equipment is hidden between the suspended ceiling and the structural floor. This equipment is connected to the bottom of the structural floor and located above the suspended ceiling, generating noise when in operation. Traditionally, the suspended ceiling is filled with soundproofing materials to reduce this noise. However, since operating existing equipment inevitably generates vibrations, these vibrations are directly transmitted to the structural floor and then to the walls, causing damage and posing a safety hazard. This is particularly true in areas with stringent acoustic and vibration reduction requirements, such as international and domestic conference centers, exhibition centers, airports, libraries, schools, hospitals, and restaurants. Utility Model Content

[0011] A further improvement of the sound-absorbing and sound-insulating shock-absorbing ceiling structure of the present invention is that the shock-absorbing hanger also includes a limit nut for limiting the maximum insertion depth of the screw rod, the limit nut is located outside the shock-absorbing box and is threadedly connected to the screw rod, and the size of the limit nut is larger than the through hole.

[0026] The following describes the embodiments of the present invention through specific examples. Those skilled in the art will readily understand the other advantages and benefits of the present invention from the disclosure herein. The present invention may also be implemented or applied through various other specific embodiments, and the details in this specification may be modified or altered based on different perspectives and applications without departing from the spirit of the present invention.

[0027] The sound-absorbing and sound-insulating vibration-damping ceiling structure of the present invention is further described in detail below with reference to the accompanying drawings and specific embodiments.

[0028] See also Figures 1 and 2 , the sound-absorbing and sound-insulating shock-absorbing ceiling structure includes:

[0029] The upper ceiling for sound insulation is located below the structural floor 1. A plurality of damping hangers 5 are connected between the upper ceiling and the structural floor 1. Existing equipment is attached to the bottom surface of the upper ceiling. The vibration of the existing equipment will drive the upper ceiling to vibrate together, and the damping hangers 5 will adaptively absorb the vibration.

[0030] The lower ceiling 7 is used for sound absorption, and a plurality of connecting rods 6 are connected to the structural floor 1 at intervals. The plurality of connecting rods 6 are staggered with the plurality of damping hangers 5, and the upper ceiling is provided with corresponding through holes for the plurality of connecting rods 6 to pass through.

[0031] Specifically, the existing equipment is connected to the bottom of the structural floor 1 through a hanger and rests against the lower surface of the upper ceiling. A socket for the hanger to pass through is provided on the upper ceiling. When the equipment vibrates during operation, the entire upper ceiling will vibrate together, and multiple shock-absorbing hangers 5 will adaptively perform shock absorption.

[0032] Preferably, the shock absorbing suspension rod 5 comprises:

[0033] A damping box 501, the top of which is connected to the structural floor 1 via expansion bolts 506;

[0034] A vertically arranged screw rod 502, one end of which is connected to the upper ceiling 7, and the other end is inserted into the shock absorbing box 501. The inserted end of the screw rod 502 is connected to a stop block 503. The bottom end of the shock absorbing box 501 is provided with a through hole for inserting the screw rod 502, and the size of the stop block 503 is larger than the through hole;

[0035] The damping spring 504 is located in the damping box 501 and is sleeved on the outer circumference of the screw rod 502. One end of the damping spring 504 is connected to the stop block 503, and the other end is connected to the inner bottom wall of the damping box 501.

[0036] The vibration of the existing equipment will drive the upper ceiling to vibrate, and the upper ceiling will drive the screw rod 502 to vibrate up and down. The shock absorbing spring 504 always provides a reaction force to prevent the vibration of the screw rod 502 for shock absorption.

[0037] Preferably, the damping suspension rod 5 also includes a limiting nut 505 for limiting the maximum insertion depth of the screw rod 502. The limiting nut 505 is located outside the damping box 501 and is threadedly connected to the screw rod 502. The size of the limiting nut 502 is larger than the through hole.

[0038] By setting the limiting nut 505, when the up and down vibration amplitude of the screw rod 502 is too large, the limiting nut 505 will block the through hole and prevent the screw rod 502 from being further inserted, thereby limiting the elongation amplitude of the shock-absorbing spring 504, preventing the screw rod 502 from increasing its insertion depth as the vibration amplitude increases, thereby preventing the shock-absorbing spring 504 from being over-stretched due to the increase in the vibration amplitude, thereby affecting the service life of the shock-absorbing spring 504.

[0039] Preferably, the upper ceiling comprises:

[0040] A first grid-like keel frame 2 , the first grid-like keel frame 2 comprising a plurality of first grid units, the first grid-like keel frame 2 being connected to the screw rod 502 ;

[0041] A sealing plate 4 is connected to the bottom of the first grid-shaped keel frame 2 and is provided with the through hole;

[0042] The first sound absorbing layer 3 is placed on the top of the sealing plate 4 and filled in each of the first grid units.

[0043] Specifically, the sealing plate 4 is a cement fiber board, and the cement fiber board is connected to the first grid-shaped keel frame 2 by bolts.

[0044] Preferably, the lower ceiling 7 comprises:

[0045] A second grid-like keel frame, the second grid-like keel frame comprising a plurality of second grid units, the second grid-like keel frame being connected to the connecting rod 6;

[0046] a sound-absorbing panel connected to the bottom of the second grid-shaped keel frame;

[0047] A second sound absorbing layer is placed on the top of the sound absorbing board and filled in each of the second grid units.

[0048] Specifically, the first sound absorbing layer 3 and the second sound absorbing layer both include glass wool and a glass fiber cloth bag for wrapping the glass wool.

[0049] By arranging the glass wool bag to wrap the glass wool, it is prevented that when the upper ceiling vibrates along with the existing equipment, the glass wool is vibrated out of the corresponding first grid unit, thereby preventing the sound insulation effect from being affected.
