Detailed Description
The present application is described in further detail below with reference to figures 1-3.
The embodiment of the application discloses interior sound-proof wall of office. Referring to fig. 1 and 2, the soundproof wall in the office includes a wall body 1 for sound insulation and an airbag net 2 for flame retardancy; the air bag net 2 is arranged in the wall body 1, the air bag net 2 comprises a plurality of air bags 21, and inert gas is filled in the air bags 21. When the fire spreads to the air bag 21, the inert gas in the air bag 21 is heated and expanded to expand the air bag 21, and the inert gas wraps the wall 1 to isolate oxygen and weaken the fire of the wall 1.
Referring to fig. 2, the wall 1 includes two layers of wall panels 11, and the two layers of wall panels 11 are respectively disposed on two sides of the wall 1 to support the wall 1. Each wall panel 11 comprises two wall panels 11 with a sandwich 111 between the two wall panels 11. The sound-proof felt 1111 and the flame-retardant mud 1112 are fixed in the interlayer 111, and the flame-retardant mud 1112 is positioned on one side of the sound-proof felt 1111, which is close to the outer side of the wall body 1.
The primary sound insulation by the deadening felt 1111 is performed to reduce the amplitude of the sound wave passing through the wall panel 11, thereby reducing the volume of sound passing through the wall body 1; the fire retardant mud 1112 is used for preliminary fire retardation, so that the fire is prevented from spreading to an adjacent room through the sound insulation wall body 1 as much as possible.
The sound absorption cotton 12 is filled between the two layers of the wall boards 11, and the sound absorption cotton 12 can wrap and protect the air bag 21, so that the air bag 21 is prevented from bursting under the influence of external force; can also inhale the sound, convert the vibrations of sound wave into the heat of inhaling the friction between the sound cotton to slow down the propagation of sound wave, reach syllable-dividing effect.
The sound-absorbing cotton 12 is made of glass fiber sound-absorbing cotton 12, the sound-absorbing cotton 12 made of glass fiber material is difficult to ignite in the air or under the high-temperature effect, is not easy to spread quickly, and is burnt immediately after the fire source is removed, so that the sound-absorbing cotton has a good flame-retardant effect.
In order to support wallboard 11 and sound absorption cotton 12 more steadily, sound absorption cotton 12 border is fixed with fossil fragments 13, fossil fragments 13 and wallboard 11 fixed connection, and the fossil fragments adopt the H shaped steel that support stable performance.
In order to splice the wall body 1 steadily, the both sides border of wall body 1 is provided with the connection sand grip 14 and the coupling groove 15 of mutually supporting respectively, connects sand grip 14 and wallboard 11 integrated into one piece, pegs graft through the cooperation between connection sand grip 14 and the coupling groove 15, pegs graft the installation between the wall body 1. The cooperation between connection convex strip 14 and the connecting groove 15 has prolonged the gap between the wall body 1, has strengthened the energy consumption that passes the sound wave from the gap, makes the syllable-dividing effect of wall body 1 better.
The connecting convex strip 14 is provided with a mounting groove 141, and a fireproof sealing strip 1411 is embedded in the mounting groove 141; when fire spreads to the wall body 1, the fireproof sealing strip 1411 at the position of a fire heat source expands rapidly along with the rise of temperature to form a local compact object to block gaps so as to prevent the permeation and spread of gas and smoke in the case of fire, and reduce loss of time for winning rescue and maximum limit.
Referring to fig. 2 and 3, the airbag net 2 further includes a connecting portion 22 for connecting the airbags 21, the airbags 21 are arranged at intervals along the plane of the wall 1, and the connecting portion 22 connects the airbags 21 arranged in a longitudinal and transverse direction to form the airbag net 2 with a net structure. When the fire spreads along the wall 1, the airbags 21 are sequentially expanded along the fire spreading direction to burst inert gas, so that the influence of the burst airbags 21 on the adjacent airbags 21 is reduced, and the flame retardance is only performed on the burning part.
Referring to fig. 3, each air bag 21 includes an air-filled layer 211 and a dry powder layer 212 arranged from inside to outside, and the dry powder layer 212 is a sandwich layer outside the air-filled layer 211; inert gas is filled in the inflatable layer 211, and flame-retardant dry powder is filled in the dry powder layer 212. When the cable meets fire, the gas in the inflation layer 211 is heated to expand, so that the air bag 21 is expanded and further explodes, the flame-retardant dry powder in the dry powder layer 212 is sprayed, the sound-absorbing cotton 12 is isolated from oxygen in a burning place, and the sound-absorbing cotton 12 stops burning, so that the flame-retardant effect is achieved on the wall body 1 which is on fire, and the spread of the fire is relieved.
In this embodiment, the inert gas filled in the gas filling layer 211 is carbon dioxide, which has a density greater than that of oxygen and can cover the combustion part, so as to isolate the combustion part from oxygen and weaken the fire of the cable in case of fire.
The implementation principle of the sound insulation wall in the office is as follows: firstly, the flame retardant mud 1112 in the interlayer 111 of the wallboard 11 can carry out primary flame retardance on the wall body 1 in fire, so as to reduce the fire behavior and the spread speed of the fire behavior; when the fire spreads to the airbag network 2, the carbon dioxide in the airbag 21 is heated to expand, so that the airbag 21 explodes, the flame-retardant dry powder in the dry powder layer 212 is ejected, and the carbon dioxide and the flame-retardant dry powder retard the flame of the wall together, thereby slowing down the spread of the fire. Meanwhile, as the temperature rises, the fireproof sealing strip 1411 rapidly expands to form a local compact object to block a gap so as to prevent the permeation and spread of gas and smoke in the case of fire, so that the time for winning rescue is reached, and the loss is reduced to the maximum limit.
The above embodiments are preferred embodiments of the present application, and the protection scope of the present application is not limited by the above embodiments, so: all equivalent changes made according to the structure, shape and principle of the present application shall be covered by the protection scope of the present application.
