Description
Technical Field
The utility model relates to an insulated door technical field, in particular to novel two-way fire prevention soundproof door.
Background
With the development of material technology, doors do not only play a role in anti-theft or privacy protection as before, but also need to have sound insulation performance and fire resistance performance, and especially in some special places, such as KTV or cinema, etc., the sound insulation performance and the sound absorption performance are guaranteed, so that external interference can be avoided, and simultaneously, sound quality and the like are prevented from being influenced by internal sound source diffusion.
SUMMERY OF THE UTILITY MODEL
The to-be-solved technical problem of the utility model is to provide a novel two-way fire prevention soundproof door to solve the technical problem in the above-mentioned background art.
The technical scheme of the utility model is that:
the utility model provides a novel two-way fire prevention soundproof door, including the door frame, door frame mid-mounting perforated plate, perforated plate both sides face is separated for a plurality of square draw-in grooves by the shelves strip, all inlays in square draw-in groove and is equipped with the acoustic celotex board, transversely perhaps vertically set up the through hole in the acoustic celotex board, all pack in the through hole and inhale the sound cotton, all laid the damping acoustic celotex board outside the acoustic celotex board, the damping acoustic celotex board outside covers the pottery aluminium abatvoix, still is provided with joint strip along the door frame outside.
Further, the sound-absorbing cotton is polyester fiber.
Furthermore, the upper surface of the sealing rubber strip is provided with a trapezoidal groove, and a plurality of silencing holes are formed in the sealing rubber strip along the length direction.
Furthermore, the acoustic celotex board is fire-retardant bamboo wood fibre pressboard.
Furthermore, the cross section of the through hole is elliptical.
The utility model discloses an useful part lies in:
the utility model discloses having synthesized and having inhaled the dual function of sound and amortization, both can having reduced indoor sound wave reflection, also can keep apart external sound wave transmission, give sound insulation, amortization and fire prevention are both two-way moreover, are particularly suitable for the cinema, and the use in places such as KTV inlays the dress structure and makes that the acoustic celotex board can be split transportation and manufacturing, reduces the cost of transportation, adopts moreover to clamp, and the installation is also convenient very.

In the figure: 1-a door frame, 2-a porous plate, 21-a stop strip, 3-a sound insulation plate, 31-a through hole, 32-sound absorption cotton, 4-a damping sound insulation plate, 5-a ceramic aluminum sound absorption plate, 6-a sealing rubber strip, 61-a trapezoidal groove and 62-a sound absorption hole.
Detailed Description
The following description will further explain embodiments of the present invention with reference to the drawings. It should be noted that the description of the embodiments is provided to help understanding of the present invention, but the present invention is not limited thereto. In addition, the technical features related to the embodiments of the present invention described below may be combined with each other as long as they do not conflict with each other.
As shown in fig. 1-4:
the utility model provides a novel two-way fire prevention soundproof door, includes door frame 1, 1 mid-mounting perforated plate 2 of door frame, 2 both sides of perforated plate are separated for a plurality of square draw-in grooves by shelves strip 21, all inlay in square draw-in groove and are equipped with acoustic celotex board 3, transversely perhaps vertically set up through hole 31 in the acoustic celotex board 3, all fill in through hole 31 and inhale sound cotton 32, all laid damping acoustic celotex board 43 outside acoustic celotex board 3, damping acoustic celotex board 43 outside covers pottery aluminium acoustic celotex board 5, still is provided with joint strip 6 along the 1 outside of door frame.
The utility model discloses a two-sided symmetry sets up, possess two-sided equal fire-retardant ability, the centre adopts perforated plate 2 to form and supports and separate, perforated plate 2 possesses good noise cancelling action simultaneously, acoustic celotex board 3 all inlays the dress and forms two-way syllable-dividing in the square draw-in groove of perforated plate 2 both sides face, transversely perhaps vertically set up through hole 31 in acoustic celotex board 3, when playing and reducing the sound wave transmission, still filled the energy that inhales cotton 32 consumption sound wave, turn into internal energy after turning into mechanical energy with its vibration and fall, in order to reduce through hole 31 to acoustic celotex board 3's structural strength damage, the better ellipse of stress dispersion effect can be taken in through hole 31 cross-section, it then adopts polyester fiber to inhale cotton 32 can, although rock wool fire prevention degree is higher, but its environmental protection is low, and the utility model provides an all materials possess fire behavior, and ceramic acoustic celotex board 5 fire rating is high, can directly prevent the intensity to stretch to the door, so adopt polyester fiber better selection undoubtedly, the material of acoustic celoted wood fiber pressboard 3 itself can adopt its fire-retardant plywood material, because of composite material, numerous good noise cancelling performance has just possessed.
Sealing rubber strip 6 is mainly used for sealing the crack, in order to increase its sealed sound-proof capability, can be equipped with trapezoidal recess 61 at sealing rubber strip 6 upper surface, closes the back, and the partial air in recess is discharged, possesses certain vacuum, and a plurality of bloops 62 are seted up along length direction to inside simultaneously, reduces the transmitting capacity of sound wave.
The utility model discloses having synthesized the dual function of inhaling sound and amortization, both can having reduced indoor sound wave reflection, also can keeping apart external sound wave transmission, sound insulation, amortization and fire prevention are both two-way moreover, and what acoustic celotex board 3 inlayed the dress structure makes acoustic celotex board 3 can the partition transportation and make, reduces the cost of transportation, adopts to clamp moreover, and it is also very convenient to install.
The embodiments of the present invention have been described in detail with reference to the accompanying drawings, but the present invention is not limited to the described embodiments.
