Is provided.

[0004]

However, in the configuration in which the door is closed between the door and the frame by the door flap, it takes a lot of man-hours to form the door flap, and there is a danger that a finger is caught in the door flap. There is a problem that there is a problem such as that there is a problem, and there is a problem that it takes a lot of man-hours to attach the sound insulating member, and furthermore, it is not possible to completely shield the door and the frame, and the door between the doors when a fire occurs. There was a point.

[0005] Therefore, an object of the present invention is to provide a fire door capable of completely shielding a gap between the fire door and the frame and a gap between the fire doors.

[0006]

SUMMARY OF THE INVENTION Accordingly, the present invention is directed to a fire door for opening and closing an opening, wherein a portion of an outer circumferential surface of the fire door is opposed to a portion of the outer surface of the fire door facing the door when the fire door is closed. A shielding member for shielding the space is provided, and a foaming member that foams at a predetermined temperature is arranged along the shielding member (claim 1). In addition, a first fireproof soundproofing member is configured by the shielding member and the foaming member.

Therefore, when the fire door is closed, the gap between the outer peripheral surface of the fire door and the portion facing the fire door is closed by the shielding member, so that sound leakage and the like can be prevented. As a result, the space between the outer peripheral side surface of the fire door and the portion facing the fire door is closed by the foam member, so that the function as the fire door can be sufficiently fulfilled.

In the present invention, a contact portion with which the shielding member comes into contact is formed at a portion where the shielding member faces, and a foaming member which foams at a predetermined temperature is disposed along the contacting portion. (Claim 2). The contact portion and the foam member constitute a second fire and soundproof member.

Further, the foam member is disposed along both sides of the shielding member (Claim 3).
It is arranged on both sides of the contact portion (claim 4).

Further, it is desirable that the foam member is a member which starts foaming at 100 degrees Celsius. This is because the temperature is not the temperature reached in a normal state, and if it is too high, the reaction may be too slow.

[0011]

Embodiments of the present invention will be described below with reference to the drawings.

FIG. 1 shows an example of an attached state of fire doors 3 and 4 for opening and closing an opening 2 formed in a frame 1. In this example, the fire doors 3 and 4 are arranged in a double-opening manner, and a first fire prevention soundproof member 5 is arranged on the outer peripheral side surface of one fire door 3. Second fireproof and soundproof members 6 and 7 are disposed on the other fireproof door 4 in contact with the first fireproof and soundproof member 5 and on the peripheral edge contact portion of the opening 2.
Reference numeral 8 denotes a handle provided on the fire doors 3 and 4.

The first fireproof soundproofing member 5 is mounted and fixed in a concave groove 32 formed in the outer peripheral side surface 31 of the fire door 3, and is formed in a concave shape so as to fit in the groove 32. The shielding member 52 fitted in the mounting portion 51 and the foam members 53 and 54 arranged along both sides of the shielding member 52. Further, the first fireproof soundproofing member 5 may be fixed in the groove portion 32 or may be fixed by screws or the like. Further, a spacer may be mounted in a space defined between the groove 32 and the first fire prevention member 5.

The shielding member 52 is constituted by a holding portion 52a sandwiched and fixed between the foam members 53 and 54, and a closing portion 52b protruding outward from the holding portion 52a. It is usually formed by an elastic member made of rubber, synthetic rubber, synthetic resin, or the like. This can prevent sound or the like from leaking from the gap.

The foam members 53 and 54 are usually made of zeolite or synthetic zeolite, but may be non-flammable members which foam at a predetermined temperature. It is preferable that the foam members 53 and 54 foam at about 100 degrees Celsius. If the temperature is lower than 100 degrees Celsius, there is a risk of foaming due to a predetermined environmental factor (such as a case where the temperature rises due to direct contact with light or the like),
This is because, when foaming is performed at a temperature higher than 100 degrees Celsius, a problem occurs in that the reaction to a fire is delayed.

Further, the second fireproof soundproofing member 6 disposed at a position facing the first fireproof soundproofing member 5, particularly, at the opposite side of the fireproof door 4, has a concave shape formed on the outer peripheral side surface 41 of the fireproof door 4. The mounting portion 61 is formed in a concave shape so as to fit in the groove portion 42, and a contact portion 62 and a corresponding contact portion 62 fitted in the mounting portion 61 are formed. And foam members 63 and 64 arranged along both sides. Further, the contact portion 62 is similar to the shielding member 52,
It is sandwiched and fixed between the foam members 53 and 54, and is usually formed by an elastic member formed of rubber, synthetic rubber, synthetic resin, or the like. The method for mounting and fixing the second fire and soundproofing member 6 to the groove 42 is preferably the same as the method for mounting and fixing the first fireproof and soundproofing member 5 to the groove 32 described above.

The second fireproof and soundproofing member 6 is arranged at a position facing the first fireproof and soundproofing member 5, particularly at the groove 12 formed on the side surface 11 of the frame 1.
As a result, all the gaps around the fire doors 3 and 4 are blocked by the first and second fire prevention soundproof members 5 and 6, so that noise and the like in the room closed by the fire doors 3 and 4 are reduced. It is possible to prevent leakage to the outside. Further, when a fire occurs from one of the indoor and the outdoor, which is shut off by the fire prevention doors 3, 4, the foam member 5
3, 54, 63, and 64 are foamed to reliably fill the gaps, so that flames, smoke, and the like can be reliably shut off.

In the second embodiment of the first fire and soundproofing member 5 shown in FIG. 4, the mounting portion 501 has holding portions 505 and 506 for holding the foam members 503 and 504, and the holding portion 505. , 506 are the shielding members 502
Of the fire doors 3, 4
In this case, the shielding member 502 can be securely held from a load on the shielding member 502 when the shutter is opened and closed, and the foam members 503 and 504 can be protected from the load.

Further, the first fire and soundproofing member 5 shown in FIG.
In the third embodiment, the mounting portion 507 has holding portions 511 and 512 for holding the foam members 509 and 510. Further, between the holding portions 511 and 512, a shielding member holding portion 513 that holds the holding portion 508a of the shielding member 508 is formed independently. The shielding member holding portion 513 is a holding portion 508a of the shielding member 508.
Is constituted by a fitting portion 513a fitted with the fixing portion 513b fixed to the mounting portion 507 by a screw 514, so that the load on the shielding member 508 applied when the fire doors 3 and 4 are opened and closed can be surely reduced. This can hold the shielding member 502 and protect the foam members 503 and 504 from the load.

Although the fire door has been described as a double-opening door in the above embodiment, the same effect can be obtained with a single-opening door. In this case, since the fire door has the same configuration as the fire door 3 described above, and the portion where the outer peripheral side of the fire door 3 faces all becomes the wall surface of the frame, the second fire prevention soundproof member 6 is formed. Are all to be mounted in grooves formed in the wall surface.

[0021]

As described above, according to the present invention,
On the outer peripheral side surface of the fire door, a shielding member for shielding between a portion where the outer peripheral side surface of the fire door faces when the fire door is closed is provided, and a foam member that foams at a predetermined temperature along the shielding member is provided. By providing this, the sound leaking from the gap of the fire door can be shielded, and at the time of fire, the foam member foams and the gap is reliably shielded, so that the inside and outside of the fire door can be reliably shut off It is.

In addition, since the above structure eliminates the need for door jamming, it is possible to prevent finger jamming at the door jamming portion and to provide an effect that the opening can be widened.
