Description

  The present invention relates to a joinery having locks such as a sliding window, a sliding window, a raising / lowering window, a case window, and a door.

In the sliding window, the indoor shoji summon and the outdoor shoji summon are overlapped in the indoor exterior direction with the indoor shoji and outdoor shoji in the closed position.
Such a sliding window is deformed so that the summoning baskets are separated from each other in the indoor outside direction due to the elongation and warpage of the summing bowls due to heat from the heating surface side in the event of a fire. For this reason, a gap is formed between the summoning bowls, and the flame passes through the gap, resulting in poor fire protection performance.

Japanese Patent Application Laid-Open No. H10-228561 discloses a sliding window that attempts to solve this problem.
This sliding window is provided with a sheet of thermally expandable refractory material on the indoor shoji summon screen and outdoor shoji summon screen, and the thermal expandable refractory sheet thermally expands in the event of a fire. The gap between the ridges is closed to prevent the flame from passing through.

JP 2005-351008 A

At the sliding window, attach a lock such as a crescent lock near the center in the longitudinal direction of both the indoor shoji summon and the outdoor shoji summon, and lock both summons together with the shoji closed. It is locked with.
For this reason, since the center of the summoning bowl is locked by the lock, the summoning bowls are deformed so that they are separated from each other in the interior and exterior direction at the beginning of the fire. However, if the above-mentioned restraint is weakened due to the fact that the lock is melted due to heat, etc. over time after the occurrence of the fire, the summon bowls start to deform so that they move away from each other in the interior and exterior direction. A gap is formed between the mating ridges.
On the other hand, the upper and lower ends of the summon bowl are not constrained by a lock, so they are more likely to be deformed away from each other in the direction of the interior of the room compared to the vicinity of the center of the summit bowl. There is a gap in
In other words, in a sliding window that locks the summon bowls with a lock, a fire will occur near the center where the summon bowl locks, and at the upper and lower ends that are not locked with the sump bowl lock. There is a time lag until a gap is generated.

Because of this, by increasing the temperature at which the thermal expansion of the sheet of thermal expansion refractory material provided on the summon bowl starts, a sheet of thermal expansion refractory material is formed when a gap occurs near the center of the sump bowl. When the thermal expansion is started, the heat-expanding refractory material does not thermally expand when a gap is formed between the upper end and the lower end of the summon bowl, so that the flame passes through the gap.
On the other hand, the thermal expansion of the sheet of the thermally expanded refractory material provided on the summon bowl is reduced, and the expanded refractory material is thermally expanded when gaps are formed at the upper and lower ends of the summit bowl. Start and close the gap, the sheet of thermal expansion refractory material provided near the center of the summon bowl will start thermal expansion with no gap between the summit bowls. The lock restraint is weakened because it tries to deform so that the center of the summon bowl is separated.
Moreover, when the time has elapsed since the occurrence of the fire, the thermal expansion of the sheet of the thermally expanded refractory material has been completed when the deformation has started so that the center of the summon jars are separated from each other toward the outside of the room. A gap generated by deforming the vicinity of the center so as to be separated from each other toward the outside of the room cannot be closed, and a flame passes through the gap.

  The present invention has been made in view of the above-mentioned problems, and its purpose is to close a gap formed between a bag and a member to be locked at the time of a fire with a heating foam material, thereby providing a joinery excellent in fire resistance. It is.

The present invention is a joinery comprising a lock that locks a lock of a building concrete to a lockable member that is opposed to the lock over the entire length in the length direction,
Attaching the lock across the longitudinal intermediate portion of the heel and the longitudinal intermediate portion of the member to be locked,
A heating foam material is provided between opposing surfaces of the heel and the locking member over the entire length in the length direction of the heel and the locking member,
The heating foam is formed between the opposing surfaces of the flange and the locking member in the longitudinal direction, and the opposing surfaces of the flange and the locking member in the longitudinal direction. It is the joinery characterized by including the heating foam material which starts foaming at low temperature rather than the heating foam material between.

  ADVANTAGE OF THE INVENTION According to this invention, the clearance gap produced between the coffin and the to-be-locked member at the time of a fire can be plugged up with a heating foaming material, and it can be set as the fitting excellent in fire prevention property.

As shown in FIG. 1, the joinery 1 includes a frame 2 and a building concrete attached to the frame 2 so as to be freely opened and closed.
The joinery 1 shown in FIG. 1 has a construction concrete of a first shoji 3 attached to the indoor side of the frame 2 so as to be opened and closed and a second shoji 4 attached to the outdoor side of the frame 2.
The frame 2 has a rectangular shape with an upper frame 2a, a lower frame 2b, a first vertical frame 2c, and a second vertical frame 2d.
The first shoji 3 and the second shoji 4 are movable in the length direction of the upper frame 2a and the lower frame 2b of the frame body 2 and move in a sliding manner between the closed position and the open position.
Thereby, the joinery 1 is used as a sliding window.

The first shoji 3 has an upper rod 30, a lower rod 31, a summoning rod 32, and a door-to-door rod 33 connected in a square shape, and a face material 34 is mounted therein.
The second shoji 4 has an upper rod 40, a lower rod 41, a summing rod 42, and a door-to-door rod 43 connected in a square shape, and a face material 44 is mounted therein.
A lock, such as a crescent tablet, is provided across the lengthwise intermediate portion (upper and lower intermediate portion) of the summing rod 32 of the first shoji 3 and the lengthwise intermediate portion (upper and lower intermediate portion) of the summing rod 42 of the second shoji 4. 5 is attached.
By placing the first shoji 3 and the second shoji 4 in the closed position, the summoning rods 32 and 42 overlap each other in the indoor exterior direction, and the door-holding rod 33 of the first shoji 3 abuts the first vertical frame 2c. The door guard 43 of the second shoji 4 comes into contact with the second vertical frame 2d.

As shown in FIG. 2, the crescent lock 5 is attached to the lengthwise intermediate portion of the summing rod 32 of the first shoji 3 and the summing length 42 of the summing rod 42 of the second shoji 4. The crescent receiver 51 is provided, and the crescent 50 is rotated by the handle 52 so that the crescent 50 is engaged with the crescent receiver 51, so that the intermediate portion in the longitudinal direction of the summing rod 32 of the first shoji 3 and the second Lock the middle part of the summoning bowl 42 of the shoji 4 in the longitudinal direction.
That is, one summoning candy 32 or 42 is a shoji sword, the other summoning sword 42 or 32 is a locking member, and the shoji sword and the locking member are opposite to each other in the longitudinal direction.

As a result, the lengthwise intermediate portions (close to the crescent lock 5) locked with the crescent locks 5 of the summoning hooks 32, 42 are restrained from being separated from each other in the interior and exterior direction. It is possible to suppress deformation of the vicinity of the crescent lock 5 so as to be separated from each other in the indoor-outside direction due to elongation and warpage due to heat.
Since the lengthwise one end and the other lengthwise end (distant from the crescent lock 5) of the summoning bowls 32 and 42 are not restricted from moving away from each other in the interior and exterior direction, the summoning bowls 32 and 42 The crescent lock 5 and the far end in the longitudinal direction are not restrained from being deformed so as to be separated from each other in the interior and exterior direction due to heat expansion and warping, and the summoning bowl on the heated side is virtually shown in FIG. As shown by the line, it is freely deformed.

  As shown in FIG. 3 and FIG. 4, each of the saddles 30, 31, 32, 33 of the first shoji 3 and the upper and lower shims 40, 41 and 43 of the second shoji 4 are made of metal, for example, an aluminum alloy extrusion. It is a metal resin composite type having an outdoor member 60 made of a profile and an indoor member 61 made of a synthetic resin, for example, a synthetic resin extruded profile. The summing bowl 42 of the second shoji 4 is made of a metal, for example, an aluminum alloy extruded shape.

As shown in FIG. 4, in the state where the first shoji 3 and the fourth shoji 4 are in the closed position, the lengthwise total length of the lateral side surface (outside surface) 32a of the summoning rod 32 of the first shoji 3 The full length in the out-of-plane direction other side surface (inner side surface) 42a of the summing bowl 42 of the second shoji 4 opposes the indoor outer side direction.
A heating foam 6 having fire resistance is provided over the entire length in the length direction of each sump 32 and 42 between one side 32a in the out-of-plane direction and the other side 42a in the out-of-plane direction.
For example, the heating foam 6 is formed into a sheet shape, the entire length in the length direction of the out-of-plane direction side surface 32a of the summing rod 32 of the first shoji 3, and the out-of-plane direction other side surface 42a of the summing rod 42 of the second shoji 4. Adhere to the entire length in the length direction with an adhesive.
It should be noted that the heating foam 6 may be provided only on either one of the out-of-plane direction side surface 32a of the summing bowl 32 of the first shoji 3 and the other out-of-plane direction side surface 42a of the summing bowl 42 of the second shoji 4. .

  As shown in FIG. 3, the heating foam 6 has a portion locked with the crescent lock 5 of the summon bowls 32 and 42 and a lengthwise intermediate portion close to the portion to be locked (that is, near the crescent lock 5), For example, the first heating foam material 6a provided in the middle in the vertical direction and one end in the length direction away from the portion locked with the crescent lock 5 of the summon bowls 32 and 42 (that is, far from the crescent lock 5), for example, The second heating foam material 6b provided at the upper end and the other end in the length direction away from the portion locked with the crescent lock 5 of the summon bowls 32, 42 (that is, far from the crescent lock 5), for example, the lower end Is provided with a third heating foam material 6c.

The first heating foam material 6a foams at a high temperature.
The second heating foam material 6b and the third heating foam material 6c are foamed at a lower temperature than the first heating foam material 6a, that is, at a low temperature.

Because of this, when a fire occurs outside the room, the outside surface of the second shoji summoning bowl 42 is heated, and the summing bowl 42 stretches and warps. For this reason, the upper end in the length direction and the lower end in the length direction of the summoning bowl 42 are deformed so as to be separated from the first shoji summoning bowl 32 in the early time zone from the occurrence of the fire, and in the early time zone from the occurrence of the fire. A gap is created.
Since the middle portions in the length direction of the summon bars 32 and 42 are restrained by the crescent lock 5 from being separated from each other in the interior and exterior direction, the middle portions in the length direction of the summit collar 42 of the second shoji 4 Does not deform so as to be separated from the summon 32 of the first shoji 4 in the early hours from the occurrence of the fire.
If the restraint is weakened by melting the crescent lock 5 or the like at a later time period after the occurrence of the fire, the middle part of the summing bowl 42 starts to deform away from the summoning bowl 32. A gap is generated in the middle portion of the mating rods 32 and 42 in the late time zone from the occurrence of a fire.

Since the second heating foam material 6b and the third heating foam material 6c start to foam at a lower temperature than the first heating foam material 6a, the foaming starts earlier in the time zone from the occurrence of the fire. A gap generated between the upper end in the length direction and the lower end in the length direction can be closed.
Since the first heating foam material 6a starts to foam at a higher temperature than the second and third heating foam materials 6b and 6c, the foaming starts at a later time zone after the fire has occurred. A gap generated in the intermediate portion in the length direction can be closed.

  As described above, according to the sliding window of the present invention, the gap formed between the summing rod 32 of the first shoji 3 and the summing rod 42 of the second shoji 4 in the event of a fire is removed from the heating foam 6. It is a sliding window with excellent fire resistance because it does not pass through the flame.

The present invention is not limited to sliding windows, and can be applied to various windows and doors.
