Description

Soundproof fireproof single door

technical field

The utility model relates to a novel fireproof and soundproof single door, more specifically a soundproof fireproof door, which belongs to the field of building decoration products.

Background technique

After the rapid development in the field of architectural decoration in the past 10 years, with mature management concepts and construction experience, the architectural decoration industry has entered the international market; but to enter the international market, it is necessary to pass international qualification certification, and the fire protection and sound insulation The requirements are very high.

Fire doors play a key role in the field of architectural decoration; in case a building catches fire and people enter the safe area through the fire door, the fire door can not only prevent the rapid spread of fire but also prevent a large amount of smoke from spreading to the safe area. At present, domestic fire door certification certificates are not recognized abroad. Domestic fireproof wooden doors are divided into Class A, Class B and Class C fireproof wooden doors. The flame retardant time of Class A fireproof wooden doors is 90 minutes, and Class B is 60 minutes. The level is 45 minutes, and there is no sound insulation requirement. If the building catches fire, the longer the flame-retardant time of the fire door, the more people will escape and the less property damage will be caused.

Therefore, we need to develop a fire-resistant door, which can not only increase the flame-retardant time but also have the effect of sound insulation. To be precise, if our foreign customers recognize European standards, then it is necessary for us to develop a sound-proof and fire-resistant single door. Able to pass British Standard WH-UK certification and ASTM sound insulation certification.

Utility model content

Sound-proof and fire-proof single door, including doors and windows, door frames, and door lock components; the doors and windows include inner core layers, glass magnesium fiber boards, and plywood; inner core layers include perlite and flame-retardant solid wood, wherein perlite is wrapped in flame-retardant solid wood, The glass magnesium fiber board is arranged on both sides of the inner core layer, and the outside of each side of the glass magnesium fiber board also has a plywood; the door frame includes flame-retardant solid wood, glass magnesium fiber board, and plywood; the outer sides of the flame-retardant solid wood are The outside of the glass magnesium fiber board on each side is a plywood; the door lock assembly is arranged at the opening position of the door, window and door frame.

The thickness of the glass magnesium fiber board in the door and window is 9mm.

The thickness of the plywood in the door and window is 3mm.

The thickness of the glass magnesium fiberboard in the door frame is 12mm.

The plywood in the door frame has a thickness of 3mm.

The perlite is injected into the fire-resistant solid wood by fluid placement.

There is also a fireproof expansion sealing strip at the inner position where the door and window fit together with the door frame.

The door and window are also provided with a fireproof hinge near the door frame.

There is also a sound insulation strip at the external position where the door and window fit together with the door frame.

The top of the door and window also has a door closer.

The beneficial effects of the utility model are: due to the use of the inner core layer, glass magnesium fiberboard, and plywood, and the inner core layer includes perlite and flame-retardant solid wood, the combustion temperature of the door leaf reaches 1200° within 120 minutes, and the fire-resistant door does not collapse. , without obvious deformation; in addition, during the combustion process, there is no large amount of smoke exposed; the fire tongue outside the fire door does not continue to escape for more than 60 seconds; moreover, in the sound insulation test, from the sound source to the outdoor receiving sound source point, STC≥ 30DB, the fire door meets the sound insulation requirements of ASTM.

Detailed ways

Please refer to Fig. 1 to Fig. 4, the sound-proof and fireproof single-leaf door in the figure includes a door and window 1 forming a single-leaf door, a door frame 2 wrapped outside the door and window 1, and a door lock assembly 3 installed at the open position of the door and window 1.

The door and window 1 includes an inner core layer 11 , two glass magnesium fiber boards 12 and two splints 13 . The inner core layer 11 includes a layer of perlite 111 and a layer of flame-retardant solid wood 112; wherein the perlite 111 is injected into the flame-retardant solid wood 112 in the form of fluid, and after it is compacted and cured, it is sealed with a glass with good heat insulation and fire resistance. Magnesium fiber board 12, so that the flame-retardant solid wood 112 is not easy to deform. The glass magnesium fiber board 12 with a thickness of 9 mm is arranged on both sides of the inner core layer 11 , wherein each side of the glass magnesium fiber board 12 also has a layer of 3 mm thick plywood 13 on the outside. In the actual test, if the perlite 111 is not added, when the temperature is high, the door and window 1 will be easily carbonized and deformed, and the flame will easily burst out from the gap in the door, so the test fails to meet the standard. The door leaf 1 has a fireproof hinge close to the door frame 2 . There are also two fireproof expansion sealing strips 4 on the door leaf 1 as well.

The door frame 2 includes a layer of flame-retardant solid wood 112, two layers of glass magnesium fiber boards 12, and two layers of plywood 13; the outer sides of the flame-retardant solid wood 112 are 12mm thick glass magnesium fiber boards 12, and the glass magnesium fiber boards 12 on each side are The outside is the thick splint 13 of 3mm.

The flame-retardant solid wood 112, perlite 111, and glass magnesium fiber board 12 are selected as fireproof materials in the above-mentioned door leaf 1 and door frame 2 mainly because of their superior fireproof performance.

The door lock assembly 3 is a conventional component with a fireproof door lock 31 on it, and the door lock assembly 3 is arranged at the edge of the door and window 1 on the right side.

The fireproof expansion sealing strip 4 is very critical to the fireproof door. The fireproof expansion sealing strip 4 is installed at the groove of the door frame 2 and the door leaf 1. During the detection, the combustion furnace is ignited, the temperature in the furnace rises, and the fireproof expansion sealing strip 4 reaches 350° When it is heated, it will expand and block the door gap to prevent the flame and smoke from spreading to the outside.

In order to make the door leaf 1 have a sound-insulating effect, a sound-insulating strip 5 is specially installed on the outside of the door leaf 1 and the door frame 2 .

After the above-mentioned door leaf 1 is installed, the door closer 6 and other fireproof hardware can also be added.
