Description

Technical Field

[0001] The utility model relates to the technical field of fire doors, and more particularly to a fire door with smoke and sound insulation. Background Art

[0002] A fire door refers to a door that can meet the requirements of fire resistance stability, integrity, and heat insulation within a certain period of time. It is a fire partition with a certain fire resistance set in fire compartments, evacuation stairwells, vertical shafts, etc. Fire doors have the function of preventing the spread of fire and smoke, and can prevent the spread of fire within a certain period of time to ensure the evacuation of personnel.

[0003] Based on the above, the inventor found the following problems: Current fire doors are usually installed in stairwells or corridors. Since the stairs are relatively empty and have a good echo effect, it will cause an increase in noise. Most fire doors do not have sound insulation effects or only use a single layer of sound insulation material for sound insulation, resulting in limited sound insulation effects and thus reducing the practicality of fire doors.

[0004] Therefore, in view of this, research and improvement are carried out on the existing structure and deficiencies to provide a fire door with smoke and sound insulation, in order to achieve the purpose of having more practical value. Summary of the Utility Model

[0005] In order to solve the above technical problems, an embodiment of the utility model provides a fire door with smoke and sound insulation, which is specifically realized through the following technical solutions:

[0006] A fire door with smoke and sound insulation includes a main body, the main body includes a sealed door frame, both sides of the inside of the sealed door frame are hinged with fireproof door panels through hinges, a handle is provided on one side of the outer wall of a pair of the fireproof door panels, and cavities are provided inside a pair of the fireproof door panels. A sound insulation mechanism is provided inside the cavities. The sound insulation mechanism includes a flame retardant frame, a first sound absorption layer is arranged inside the flame retardant frame, a second sound absorption layer is arranged on one side of the outer wall of the first sound absorption layer, and a first sound insulation layer is arranged on the outer wall of the first sound absorption layer away from the second sound absorption layer. A second sound insulation layer is arranged on one side of the outer wall of the second sound absorption layer.

[0007] Further, a number of sound absorption tubes are equidistantly installed inside the first sound absorption layer, and a number of honeycomb holes are opened on a number of the sound absorption tubes.

[0008] The beneficial effect of adopting the above further scheme is that through the combined use of the sound absorption tubes and the honeycomb holes, since the inside of the sound absorption tubes is a double-layer structure, the first sound absorption layer has a double sound absorption effect.

[0009] Further, a number of second springs are equidistantly arranged inside the second sound absorption layer, and the second sound absorption layer is communicated with the first sound absorption layer.

[0010] The beneficial effect of adopting the above further solution is that by arranging a second spring inside the second sound-absorbing layer and setting obstacles on the sound vibration propagation path, vibration is reduced and sound is lowered, further playing a sound-absorbing role.

[0011] Furthermore, the first sound-insulating layer is made of sound-insulating board material, the second sound-insulating layer is made of sound-insulating cotton material, and a first fireproof and heat-insulating board and a second fireproof and heat-insulating board are respectively arranged on one side of the outer walls of the first sound-insulating layer and the second sound-insulating layer.

[0012] The beneficial effect of adopting the above further solution is that through the combined use of the first sound-insulating layer and the second sound-insulating layer, since the first sound-insulating layer is a sound-insulating board, the high density of the sound-insulating board can block the propagation of part of the noise, and the second sound-insulating layer is sound-insulating cotton. Through the combined use of the sound-insulating board and the sound-insulating cotton, noise of 30 - 50 decibels can be blocked. By arranging the first fireproof and heat-insulating board and the second fireproof and heat-insulating board, fireproof and heat-insulating protection is provided for the sound-insulating mechanism.

[0014] The beneficial effect of adopting the above further solution is that by arranging the installation strips, since both side edges of the installation strips far from the connecting blocks are arc-shaped, when the opened fireproof door panels are closed, their upper ends and bottom ends will be in extrusion with the side edges of the installation strips until the fireproof door panels are closed. After the installation strips are continuously extruded by the fireproof door panels and shrink into the installation grooves, when the upper ends and bottom ends of the fireproof door panels are in fit with the installation strips, the gaps between the inner bottom end and the upper end of the sealed door frame and the fireproof door panels are filled, thereby further achieving the purposes of smoke isolation and sound insulation.

[0015] Furthermore, a pair of connecting blocks are installed on one side of the outer wall of the installation strip, a sliding rod is installed inside the installation groove, a pair of sliders are slidably connected to the outside of the sliding rod, and a damping rod is hinged between the opposite sliders and the connecting blocks through a pin shaft.

[0016] The beneficial effect of adopting the above further solution is that by hinging a damping rod between a pair of corresponding sliders and connecting blocks, when the installation strip is continuously extruded by the fireproof door panels, the installation strip shrinks towards the inside of the installation groove and pushes the slider to move on the sliding rod under the action of the damping rod.

[0017] Furthermore, first springs are movably sleeved on the outer parts of both ends of the sliding rod, one end of each first spring is fixedly connected to the inner wall of the installation groove, and the other end of each first spring far from the inner wall of the installation groove is fixedly connected to one side of the outer wall of the slider.

[0018] The beneficial effect of adopting the above further solution is that by setting the first spring, when the slider moves towards both ends of the sliding rod, the first spring will be compressed, thereby realizing the insertion of the installation strip into the installation groove. After the fireproof door panel is closed, the installation strip will reset under the action of the first spring and the damping rod, so that the installation strips inside the upper and lower ends of the sealed door frame are respectively attached to the upper and lower ends of the fireproof door panel.

[0019] The beneficial effect of the present utility model is: A smoke and sound insulation fireproof door obtained by the above design of the present utility model. For this kind of smoke and sound insulation fireproof door, by setting a handle on the outside of the fireproof door panel, it is convenient to pull the fireproof door panel. By setting a sound insulation mechanism, the fireproof door panel has a sound insulation effect. By setting a flame retardant frame, the service life of the first sound absorption layer, the second sound absorption layer, the first sound insulation layer and the second sound insulation layer inside the flame retardant frame is improved. By setting the first sound insulation layer, the first sound absorption layer, the second sound absorption layer and the second sound insulation layer, the first sound insulation layer is made of sound insulation board material, and the sound insulation board can prevent the propagation of some noises through its high density property. By setting sound absorption pipes inside the first sound absorption layer, since the inside of the sound absorption pipes is a double-layer structure, the first sound absorption layer has a double sound absorption effect. By setting a second spring inside the second sound absorption layer, an obstacle is set on the sound vibration propagation path to reduce vibration and lower the sound, further playing a sound absorption role, and by setting the second sound insulation layer as sound insulation cotton, the sound is further weakened.

All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present utility model without creative efforts shall fall within the protection scope of the present utility model.

[0029] Embodiment 1

[0030] The present utility model provides the following technical solutions: As Figures 1 - 5As shown in the figure, a fire door with smoke and sound insulation includes a main body 100. The main body 100 includes a sealed door frame 1001. On both sides inside the sealed door frame 1001, there are fireproof door panels 1002 hinged by hinges. On one side of the outer walls of a pair of fireproof door panels 1002, there are handles 1003 respectively. And inside a pair of fireproof door panels 1002, there are cavities. Inside the cavities, there is a sound insulation mechanism 200. The sound insulation mechanism 200 includes a flame retardant frame 2001. Inside the flame retardant frame 2001, there is a first sound absorption layer 2002. On one side of the outer wall of the first sound absorption layer 2002, there is a second sound absorption layer 2005. And on the outer wall side of the first sound absorption layer 2002 away from the second sound absorption layer 2005, there is a first sound insulation layer 2007. On one side of the outer wall of the second sound absorption layer 2005, there is a second sound insulation layer 2008. By setting the handle 1003 outside the fireproof door panel 1002, it is convenient to pull the fireproof door panel 1002. By setting the flame retardant frame 2001, the service lives of the first sound absorption layer 2002, the second sound absorption layer 2005, the first sound insulation layer 2007 and the second sound insulation layer 2008 inside the flame retardant frame 2001 are improved. By setting the first sound insulation layer 2007, the first sound absorption layer 2002, the second sound absorption layer 2005 and the second sound insulation layer 2008, the sound is gradually weakened and blocked, so as to achieve the purpose of sound insulation.

[0031] Embodiment Two

[0032] Referring to Figures 1 - 5 As shown in the figure, a number of sound absorption pipes 2003 are equidistantly installed inside the first sound absorption layer 2002. A number of honeycomb holes 2004 are opened on a number of sound absorption pipes 2003. A number of second springs 2006 are equidistantly arranged inside the second sound absorption layer 2005. And the second sound absorption layer 2005 is communicated with the first sound absorption layer 2002. The first sound insulation layer 2007 is made of sound insulation board material, and the second sound insulation layer 2008 is made of sound insulation cotton material. On one side of the outer walls of the first sound insulation layer 2007 and the second sound insulation layer 2008, there are a first fireproof and heat insulation board 2009 and a second fireproof and heat insulation board 2010 respectively. By setting the material of the first sound insulation layer 2007 as a sound insulation board, the high density of the sound insulation board can prevent the propagation of part of the noise. By setting the sound absorption pipes 2003 inside the first sound absorption layer 2002, since the inside of the sound absorption pipes 2003 is a double-layer structure, the first sound absorption layer 2002 has a double sound absorption effect. By setting the second springs 2006 inside the second sound absorption layer 2005, obstacles are set on the sound vibration propagation path to reduce vibration and lower the sound, further playing a role in sound absorption. And by setting the second sound insulation layer 2008 as sound insulation cotton, the sound is further weakened.

[0033] Embodiment Three

[0034] Referring to Figures 1 - 5As shown in the figure, installation grooves 1004 are provided inside the upper and lower ends of the sealed door frame 1001. Installation bars 1005 are movably inserted into the pair of installation grooves 1004. Both sides of the installation bar 1005 are arc-shaped. The bottom and upper ends of the pair of fireproof door panels 1002 are respectively in pressing fit with the installation bar 1005. A pair of connecting blocks 1006 are installed on one side of the outer wall of the installation bar 1005. A sliding rod 1007 is installed inside the installation groove 1004. A pair of sliders 1008 are slidably connected to the outside of the sliding rod 1007. A damping rod 1009 is hinged between the opposite sliders 1008 and the connecting blocks 1006 through a pin shaft. A first spring 1010 is movably sleeved on the outer parts of both ends of the sliding rod 1007. One end of the first spring 1010 is fixedly connected to the inner wall of the installation groove 1004, and the other end of the first spring 1010 away from the inner wall of the installation groove 1004 is fixedly connected to one side of the outer wall of the slider 1008. By setting the installation bar 1005, when the opened fireproof door panel 1002 is closed, its upper and lower ends will be squeezed against the sides of the installation bar 1005 until the fireproof door panel 1002 is closed. When the installation bar 1005 is continuously squeezed by the fireproof door panel 1002, the installation bar 1005 contracts towards the inside of the installation groove 1004 and pushes the slider 1008 to move on the sliding rod 1007 under the action of the damping rod 1009. When the slider 1008 moves towards both ends of the sliding rod 1007, the first spring 1010 will be squeezed, so as to realize the installation bar 1005 being placed inside the installation groove 1004. After the fireproof door panel 1002 is closed, the installation bar 1005 will reset under the action of the first spring 1010 and the damping rod 1009, so that the installation bars 1005 inside the upper and lower ends of the sealed door frame 1001 are respectively in fit with the upper and lower ends of the fireproof door panel 1002, so as to fill the gaps between the inner bottom and upper ends of the sealed door frame 1001 and the fireproof door panel 1002, so as to further achieve the purpose of smoke and sound insulation.

[0035] Specifically, the working principle of this kind of fire door with smoke and sound insulation: When in use, when closing the opened fire door panel 1002 through the handle 1003, the upper and lower ends thereof will be squeezed against the side edges of the installation strip 1005 until the fire door panel 1002 is closed. When the installation strip 1005 is continuously squeezed by the fire door panel 1002, the installation strip 1005 shrinks towards the inside of the installation groove 1004 and pushes the slider 1008 to move on the sliding rod 1007 under the action of the damping rod 1009. When the slider 1008 moves towards both ends of the sliding rod 1007, it will squeeze the first spring 1010, thereby realizing that the installation strip 1005 is placed inside the installation groove 1004. After the fire door panel 1002 is closed, the installation strip 1005 will reset under the action of the first spring 1010 and the damping rod 1009, so that the installation strips 1005 inside the upper and lower ends of the sealing door frame 1001 are respectively attached to the upper and lower ends of the fire door panel 1002, thereby filling the gaps between the inner bottom end and the upper end of the sealing door frame 1001 and the fire door panel 1002, so as to achieve the purpose of smoke and sound insulation. By setting the flame retardant frame 2001, the service life of the first sound absorption layer 2002, the second sound absorption layer 2005, the first sound insulation layer 2007 and the second sound insulation layer 2008 inside the flame retardant frame 2001 is improved. By arranging the sound absorption pipes 2003 inside the first sound absorption layer 2002, since the inside of the sound absorption pipes 2003 is a double-layer structure, the first sound absorption layer 2002 has a double sound absorption effect. By arranging the second spring 2006 inside the second sound absorption layer 2005, obstacles are set on the sound vibration propagation path to reduce vibration and lower the sound, further weakening the sound, and by setting the second sound insulation layer 2008 as sound insulation cotton, the purpose of sound insulation is achieved.

[0036] The above are only the preferred embodiments of the present invention and are not intended to limit the present invention. For those skilled in the art, the present invention can have various modifications and changes. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present invention shall be included within the protection scope of the present invention.
