Detailed Description

The present invention will be described in further detail with reference to the accompanying drawings and specific embodiments.

Fire-retardant sound subassembly of inhaling of roofing fire prevention, including middle supporting body 1, fire-retardant layer 2, flame retardant coating 3, still include sound absorbing layer 4, two opposite flanks of middle supporting body 1 outwards set gradually sound absorbing layer 4, fire-retardant layer 2, flame retardant coating 3, middle supporting body 1 bonds with sound absorbing layer 4, sound absorbing layer 4 bonds with fire-retardant layer 2, fire-retardant layer 2 bonds with flame retardant coating 3. The thickness of the middle supporting body 1 is 30-60mm, the material of the middle supporting body 1 is foaming flame-retardant polyurethane, and in this embodiment, the thickness of the middle supporting body 1 is 50 mm.

Be equipped with the cavity 10 that is used for reducing sound and heat transfer on middle supporting body 1, in this embodiment, the high priority of cavity 10 sets up to 8mm, because cavity 10 is empty, consequently, cavity 10 has reduced sound and thermal propagation, makes the loss of acoustic energy and heat energy increase to form absorptive effect to sound and heat, and then promoted and inhaled the sound performance. The height of the cavity 10 is 2-10mm, and in this embodiment, the height of the cavity 10 is preferably 8 mm.

In this embodiment, the cavity 10 is preferably set as a vacuum chamber, and since the vacuum has a limiting effect on the propagation of sound, the propagation of sound is further reduced, and the sound insulation performance is further improved. The vacuum cavity is formed by vacuumizing, in the embodiment, a vacuumizing port 13 is arranged on the middle bearing body 1 and is communicated with the cavity 10, a sealing plug 5 is installed at the vacuumizing port 13, the sealing plug 5 comprises a handle part 50 and a sealing main body 51, the handle part 50 and the sealing main body 51 are fixed into a whole, the width of the handle part 50 is larger than that of the sealing main body 51, the vacuumizing port is a stepped hole, a small-diameter hole of the stepped hole is matched with the sealing main body 51, a large-diameter hole of the stepped hole is matched with the handle part 50, the height of the handle part 50 is equal to that of the large-diameter hole, and after the sealing plug 5 is matched with the vacuumizing port, the handle part 50 is flush with the hole opening of the large-diameter hole.

The sealing plug 5 is preferably made of rubber, and the sealing plug 5 is in transition fit with the vacuumizing port 13. The sealing plug 5 further comprises a sealing ring 52, an annular groove body is arranged on the sealing main body 51, the sealing ring 52 is matched with the annular groove body, after the vacuumizing is completed, the sealing plug 5 is inserted into the vacuumizing port 13, and the better sealing effect is formed on the vacuumizing port 13 through the sealing ring 52.

One end of the middle bearing body 1 is provided with a first convex eaves 11 used for matching two adjacent fireproof flame-retardant sound-absorbing components of two roofs, the other end of the middle bearing body 1 is provided with a second convex eaves 12 used for matching two adjacent fireproof flame-retardant sound-absorbing components of two roofs, and the first convex eaves 11 and the second convex eaves 12 are arranged in a staggered manner. The first and

second eaves

11 and 12 are 5 to 20mm in length. When this product of installation, the fire-retardant first protruding eaves 11 and the protruding eaves 12 of second of inhaling the sound subassembly of two adjacent roofing fires form the cooperation one on the other, can form the integration better to the gap that sound direct propagation has been blocked between the fire-retardant sound subassembly of inhaling of two adjacent roofing fires, thereby this kind of structure helps promoting syllable-dividing effect.
