Description
Technical field
Closed the present invention relates to being housed in the door pocket for being arranged at wall when usual and being discharged from the door pocket when on fire
The normally opened fire resistant doorsets of door.
Background technology
Normally opened fire resistant doorsets in response to it is on fire when cigarette, heat and from door pocket discharge, be switched to by so-called (door) closer
Shutdown position, side on fire and non-side on fire are interdicted to prevent flame, cigarette from being spread in building.The fire resistant doorsets as caused by closer
Shutdown action start to rotate with larger speed firm, if close to shutdown position, braking function works, gradually slow down and
Reach shutdown position.But according to situation on fire, exist because the air caused by fire expands, fire resistant doorsets are by that should close
The opening portion of door produces strong air stream, due to its blast, the action for the fire resistant doorsets that will be closed the door is hindered, sometimes into nothing
The situation for the state that method is closed the door.That is, due to putting on the face side of fire resistant doorsets and the pressure differential of reverse side, in fact it could happen that closing
Situation about can not be closed the door under the force of device.
All the time, it has been realized that when fire occurs by acting on the surface of fire resistant doorsets and the pressure differential of reverse side
Caused this problem, and attempt solve the problem.For example, from it is usual when be in the normally closed fire resistant doorsets of shutdown state,
In the presence of due to occurring pressure differential as described above caused by fire, the people positioned at side on fire can not open the fire resistant doorsets (when
When fire resistant doorsets are larger, the side door (taking refuge with switch gate) for the pivoted for referring to be disposed therein), can not be carried out by the fire resistant doorsets

Patent document 2：Japanese Unexamined Patent Publication 2002-272866 publications
But do not proposed to overcome normally opened fire resistant doorsets so far yet, i.e., be contained in door pocket when usual, when on fire from door
Technology the problem of hindering set for closing fireproof door because of blast (pressure differential) as described above for the fire resistant doorsets that set discharges and closed the door.
The content of the invention
It is an object of the invention to overcome normally opened fire resistant doorsets it is such the problem of.
The invention provides normally opened fire resistant doorsets, when fire occurs, normally opened fire resistant doorsets with along a lateral edges in vertical direction
Pivot and close the door centered on the first axle of upper extension, the normally opened fire resistant doorsets have：Decompression opening, from the surface of the fire resistant doorsets
Penetrate to reverse side；Decompression door, installed by closing the decompression in a manner of opening, around with the almost parallel extension of the first axle
Second axis rotates and can open the decompression opening；And door closer is used in decompression, around the second axis to the decompression door
Force, the decompression door is set to be in the shutdown position for closing the decompression opening, the position of the second axis is：When this is normally opened anti-
Vent pivoted centered on the first axle when on fire and at closing time, using the action with the shutdown in the decompression door
In caused by rotation torque more than the setting of the second axis, the decompression resists applying for the decompression door closer with door
Power and rotate, and open decompression opening.
Normally opened fire resistant doorsets rotate around first axle to shutdown direction when on fire.Therefore, towards the door surface in shutdown direction
Velocity of rotation near first axle is slow, and with first axle is left, velocity of rotation accelerates.Thus, it is big with its speed difference
About square proportional Action of Wind pressure is in door surface.Therefore, by the way that second axis to be arranged to appropriate position, so as to make pair
Resistance to decompression acts on decompression door with the rotation torque of door closer, and decompression is rotated with door and decompression is opened with opening.If often
Open fire resistant doorsets and be in shutdown position without being rotated further around first axle, then above-mentioned speed difference disappears, because above-mentioned rotation torque disappears
Lose, therefore decompression door is closed the door by decompression with door closer.
Specifically, the second axis can be located at the centre position of the width of the decompression door.
By the way that in this way, being in the state of shutdown position even in normally opened fire resistant doorsets, (therefore, namely above-mentioned speed difference disappears
The state of mistake) under pressure put on the surface reverse side of the normally opened fire resistant doorsets and decompression door, due to by putting on decompression door
Rotation torque caused by the pressure of the left and right sides of second axis is acted in a manner of cancelling out each other, therefore can also not increased excessively
Big decompression with door by decompression with being maintained at shutdown state in the case of the force of door closer.
But according to circumstances, the second axis can also be located at the centre position of the width than the decompression door more
Position away from the first axle.When being in shutdown position in normally opened fire resistant doorsets, in the state of decompression is in shutdown position with door,
When pressure puts on the face in direction shutdown direction of normally opened fire resistant doorsets, put on because of the pressure decompression door around second axis
Rotation torque become the force direction of decompression closer, therefore decompression more reliably can be maintained at shutdown position with door
Put.
Furthermore it is possible to there is upper hinge device and underneath hinges device, the upper hinge device and underneath hinges device
Have edge should between top edge and the lower edge top edge corresponding with the decompression opening and lower edge of the decompression door
The joint pin of second axis extension, and the decompression door can be made to be rotated around the joint pin.
In this case, the decompression door closer can have a helical spring, and the helical spring is same around the joint pin
Shaft-like is set, and fixation is wound with the door opening action of the decompression door.
At least one in the upper hinge device and the underneath hinges device has the first cartridge and the second tubular
Part, first cartridge and the second cartridge, so that upper and lower relation configures and houses the joint pin, divide along the second axis
The normally opened fire resistant doorsets and the decompression door are not fixed on, if the decompression door rotates predetermined angular from shutdown position, this first
Cartridge and the second cartridge are mutually clamped, and prevent the decompression from further being rotated with door.
Below, based on accompanying drawing, the embodiment of normally opened fire resistant doorsets involved in the present invention is illustrated.

During calamity in response to detect flame, cigarette and from door pocket A discharge, by door closer B (Fig. 2), around the side along normally opened fire resistant doorsets 10
The first axle C extended in vertical direction is switched to shutdown position, and (position out of level display door pocket A turns in Fig. 1
Dynamic 90 degree are arrived vertically displayed position) (Fig. 2), close between side F on fire and non-side N on fire to prevent flame, cigarette in building
Interior sprawling.Door closer B is configured to：Just start to rotate the normally opened fire resistant doorsets 10 discharged from door pocket A with larger speed, if close close
Door position, then braking function work, normally opened fire resistant doorsets 10 are moved to shutdown position with the state gradually slowed down.Preferably,
Normally opened fire resistant doorsets 10 are opened and closed before incipient flame on fire, cigarette become strong, but in some cases, midway are acted in shutdown, due to
Caused by fire air expansion and by strong air stream, so as to hinder shutdown to act, what entrance sometimes can not close the door
State.
In order to prevent fires, it is necessary to carry out the preparation for coping with such state, therefore, in normally opened fire resistant doorsets 10, have
Penetrate to the decompression opening 12 of reverse side from its surface (towards the face in shutdown direction) side and closed in a manner of it can open
The decompression door 14 of decompression opening 12.
In the example of diagram, decompression is rotated around the second axis D extended in parallel along first axle C with door 14 and opens decompression
With opening 12, specifically, by decompression with the top edge 16 of door 14 and the approximately mid way between of lower edge 18 along the second axle
Upper hinge device 20, the underneath hinges device 22 of line D settings, can be rotated relative to normally opened fire resistant doorsets 10.
As shown in figures 1 and 3, upper hinge device 20 has：Lower barrel part 24, it is embedded to and is fixed on decompression door
The centre position of 14 top edge 16；Top cartridge 28, alignd along second axis D with lower barrel part 24, embedment subtracts
The top edge 26 of pressure opening 12；Joint pin 30, lower barrel part 24 is fixed on, top tubular is extended to along second axis D
In part 28；And helical spring 31, set around the joint pin 30, lower barrel part 24 and top cartridge 28 can be with
Relatively rotated centered on joint pin 30.Underneath hinges device 22 can use and the identical structure of upper hinge device 20.
Helical spring 31 is along (counter clockwise direction when being observed in Fig. 2, Fig. 4) E directions effect so as to decompression door 14
Exerted a force to shutdown position, if decompression carries out door opening action, helical spring volume 31 in the clockwise direction as shown in Figure 2 with door 14
Around fixation, it forms the closer of decompression door 14.From Fig. 3 and Fig. 4, in the lower barrel part of upper hinge device 20
24 top edge is provided with substantially semi-circular protrusion holding section 32, and on top, the lower edge of cartridge 28 is again provided with greatly
Semicircular prominent holding section 34 is caused, the both ends of the protrusion holding section 32,34 are configured in the circumferential mutually relatively.Fig. 4 shows
The force by above-mentioned helical spring (decompression door closer) 31 is gone out, decompression is with door 14 by force to closing decompression opening
The state of 12 position, in this condition, when prominent holding section 32,34 is observed in figure positioned at lower position end 32a,
Be mutually clamped at 34a, lower barrel part 24 (therefore, namely decompression use door 14) relative to top cartridge 28 (therefore,
I.e. normally opened fire resistant doorsets 10) relative rotation be prevented from.As shown in figure 4, the protrusion holding section 32 of lower barrel part 24 is around
Extended in circular arc in the range of two axis D substantially 180 degrees, on the other hand, the protrusion holding section 34 of top cartridge 28 exists
Extended in circular arc in the range of substantially 170 degree, the end of position above when being observed in the figure of prominent holding section 32,34
Between 32b, 34b, about 10 degree of gap is left.Therefore, in this embodiment, it is allowed to which decompression is rotated with door 14 from shutdown position
About 10 degree.This is in order to avoid decompression is unnecessarily opened with door 14, and the angle can suitably be set as needed.In decompression door
14 turn in the state of the shutdown position of closure decompression opening 12, as described above, the protrusion holding section 32 of hinge means 20
End 32a engage with the end 34a of prominent holding section 34 and prevent it from further rotating, but in the illustrated embodiment,
As shown in Fig. 2 the both sides of the edge of door 14 are provided with the first projecting strip part 14a, the second projecting strip part 14b along decompression, when decompression door
14 when turning to shutdown position, and the first projecting strip part 14a, the second projecting strip part 14b are sticked in along the both sides of the edge of decompression opening 12
The first recess 12a, the second recess 12b of the corresponding strip formed, auxiliary prevents it from further rotating, and prevents from coming from
Side F on fire flame, cigarette enters non-side N on fire.
In the state of normally opened fire resistant doorsets 10 are contained in door pocket A, if detecting on fire, correspondingly normally opened fire resistant doorsets 10 are from door
A releases are covered, then normally opened fire resistant doorsets 10 are acted by door closer B into shutdown, anxious in the beginning of shutdown action, normally opened fire resistant doorsets 10
Play accelerates, and is closed with larger speed, if close to shutdown position, by braking function possessed by door closer B, is gradually subtracting
Stop position is moved in the state of speed.In shutdown action, towards shutdown direction normally opened fire resistant doorsets 10 surface the
Velocity of rotation near one axis C is slow, and with first axle C is left, velocity of rotation accelerates, thus, and corresponding to from first axle
The blast of the about square proportional pressure distribution of the speed difference of line C distance puts on a surface.Therefore, by by second
Axis D is arranged at appropriate position, can make to act on decompression door 14 with the rotation torque of door closer 31 to resistance to decompression, subtract
Pressure door 14 rotates and opens decompression opening 12.If normally opened fire resistant doorsets 10 are in shutdown position without further around first axle C
Rotate, then above-mentioned speed difference disappears, and rotation torque disappears, therefore decompression passes through helical spring with door 14 (door closer is used in decompression)
31 close.
Normally opened fire prevention involved in the present invention is illustrated with an embodiment of door, but the present invention is not limited to
This.For example, second axis D can not also be among the width of decompression door 14, but close or leave first axle C
Position.Even if the blast difference that normally opened fire resistant doorsets are subjected to when stopping is identical, but according to second axis D setting position, its
Rotation torque caused by surrounding is also different, therefore considers the appropriate settings such as force of helical spring (door closer is used in decompression).
