Detailed Description
In order to better understand the above technical solutions, the following detailed description will refer to the accompanying drawings and specific embodiments.
The embodiment of the utility model discloses a damping bridge-cutoff composite sound insulation door, which comprises a door frame body 1 and a door leaf body 2, wherein the door leaf body 2 is embedded in the door frame body 1, and the door leaf body 2 is movably connected with the door frame body 1 through hinges, so that the door leaf body 2 can rotate relative to the door frame body 1 in the horizontal direction. The door leaf main body 2 comprises first door leaf 21 and second door leaf 22, in order to improve the effect of door leaf main body 2 absorption noise, inlays between first door leaf 21 and the second door leaf 22 and is equipped with sound absorbing layer 7, and sound absorbing layer 7 adopts glass cotton to make. Other noise absorbing materials such as mineral wool boards may also be used in embodiments of the present utility model. The first isolation layer 3 is embedded around the sound absorption layer 7 between the first door leaf 21 and the second door leaf 22, and the first door leaf 21 and the second door leaf 22 are separated by the first isolation layer 3, so that the first door leaf 21 and the second door leaf 22 are prevented from rigidly contacting, and the influence of the sound bridge problem on the sound insulation effect is reduced. The door frame body 1 includes a first door frame 11 and a second door frame 12, and a second isolation layer 4 for isolating the first door frame 11 and the second door frame 12 is further provided between the first door frame 11 and the second door frame 12. The first isolation layer 3 and the second isolation layer 4 are made of high-density rubber particle blocks, and have certain firmness and vibration damping property.

The first damping layer 102 and the second damping layer 103 may be made of viscoelastic damping material, and may be epoxy resin. When sound waves sequentially pass through the first door leaf 21 and the second door leaf 22, the first door leaf 21 and the second door leaf 22 vibrate to drive the first damping layer 102 and the second damping layer 103 to generate elastic deformation, so that the energy of the sound is lost.
The door frame body 1 is composed of a top frame at the top, a threshold at the bottom and side frames at the two sides, and a first door frame 11 at the threshold is higher than a second door frame 12. Referring to fig. 3, the top of the door sill forms a first inclined plane 5 by the height difference of the first door frame 11 and the second door frame 12 at the door sill, and a second inclined plane 6 adapted to the door sill is also provided under the door leaf main body 2. When the door leaf body 2 and the door sill are closed, the first inclined surface 5 of the door sill is matched with the second inclined surface 6 of the door leaf body 2, so that when sound waves are injected into a gap between the door leaf body 2 and the door sill, the sound waves are reflected by the first inclined surface 5 of the door sill and the second inclined surface 6 of the door leaf body 2 for multiple times, and accordingly sound energy is lost. In order to improve the tightness between the door leaf main body 2 and the door threshold, a sealing felt 8 is paved on the surface of the first inclined surface 5 of the door threshold and the surface of the second inclined surface 6 of the door leaf.
Referring to fig. 4, the door frame body 1 is provided with first steps 9 on both the top frame and the inner side walls of the side frames, and the door leaf body 2 is provided with second steps 10 corresponding to the first steps 9 on the corresponding side walls, with a gap formed between the first steps 9 and the second steps 10. The first door frame 11 at the top frame and the side frames extends in the direction of the first door leaf 21, and a gap is formed between the first door frame 11 and the first door leaf 21. In order to improve the sealing effect between the door main body 2 and the top and side frames, a seal bar 101 is provided in each of the gaps between the first step 9 and the second step 10 and the gaps between the first door frame 11 and the first door 21. The sealing strip 101 adopts magnetic sealing adhesive tape, makes door leaf main part 2 and door frame main part 1 can closely laminate through the effect that the magnetism inhaled, improves sealed effect.
The implementation principle of the damping bridge-cutoff composite sound insulation door provided by the embodiment of the utility model is as follows: in the use process of the damping bridge-cut-off composite sound insulation door, the sound absorption layer 7 is embedded between the first door leaf 21 and the second door leaf 22, so that a large amount of noise can be absorbed. The first isolation layer 3 is embedded around the sound absorption layer 7 between the first door leaf 21 and the second door leaf 22, and the second isolation layer 4 is installed between the first door frame 11 and the second door frame 12, so that the influence of a sound bridge on the sound insulation effect is reduced. The first door leaf 21 and the second door leaf 22 are respectively provided with the first damping layer 102 and the second damping layer 103, so that the loss of sound volume is increased, and the sound insulation effect is improved. And a sealing felt 8 is paved between the door leaf main body 2 and the threshold, so that a sealing structure is formed, and the sound insulation effect is also improved.
