Description

  The present invention relates to a sash window provided with a ventilation device.

  Conventionally, as windows (sash windows), various windows (sash windows) with different opening / closing methods and functions, such as sliding windows, raising / lowering windows, FIX windows (fitting windows), external opening windows, falling windows, folding windows, rotating windows, etc. Windows) are used in buildings such as houses. In addition, aluminum sashes, steel sashes, resin sashes, and composite sashes made by combining aluminum and resin profiles are frequently used for windows of this type.

  In addition, for the purpose of, for example, measures against sick houses and energy saving, a ventilation device that supplies natural air into the room and exhausts the room air to the outside is provided on the side of the top of the sash and has a ventilation function. Sash windows are also used.

  For example, the ventilator is formed with a hollow structure and includes a casing portion that is extended in a predetermined length in the width direction of the window (longitudinal direction of the side wall). In addition, a plurality of slit-like indoor vents arranged in parallel with a predetermined interval in the width direction are formed in the housing portion so as to penetrate the indoor side wall portion, and the widthwise direction is formed in the outdoor side wall portion. A plurality of slit-like outdoor vents arranged in parallel at predetermined intervals are formed through. Furthermore, the housing part has an engaging recess for attaching to the upper end side and the lower end part, for example, by engaging it with a horizontal saddle, and a shoji holder for fitting and holding a glass panel (shoji). A recess is provided.

  Furthermore, an operating plate is provided in the hollow portion with its upper end pivotably connected above the indoor vent. In the closed position, the operation plate comes into surface contact with the inner surface of the indoor side wall portion to close the indoor side air vent, and in the open position, the operation plate is tilted with respect to the indoor side wall portion to open the indoor side air vent so that ventilation can be performed. As described above, the room communicates with the outside through the hollow portion and the outdoor vent.

  And the sash window which provided the ventilation apparatus comprised in this way in the sash can open a ventilation opening in the wall of a building like before, and it becomes unnecessary to install a ventilation apparatus. In recent years, it has been applied to many buildings because it does not deteriorate the appearance inside or outside of the room or cause a decrease in heat insulation.

  Furthermore, in order to prevent flames, smoke and heat from penetrating (circulating and propagating) through the indoor vent and outdoor vent of the ventilator in the event of a fire, a thermal expansion refractory material that is heated and expanded at a predetermined temperature There is a fire sash provided with a ventilation device provided, and thus a fire proof sash (see, for example, Patent Document 1).

  In this fireproof ventilator, a thermal expansion refractory material formed into a flat strip shape by mixing graphite with an epoxy resin, for example, at a position adjacent to the outdoor vent in the hollow portion below the working plate. Paste. And when a thermal expansion refractory material is heated above a certain set temperature at the time of a fire, it expands to fill the lower side of the hollow part and closes the outdoor vent. Thereby, it can prevent that a flame, smoke, and a heat | fever are transmitted to the non-fire side, and it can prevent that a fire spread etc. generate | occur | produce due to a ventilator.

  On the other hand, there is a sash window in which an indoor side vent or an outdoor side vent is provided on the upper beam (the horizontal beam such as the upper beam) itself, and a ventilation device is incorporated in the upper beam. By incorporating the ventilation device into the upper rail in this way, the area (lighting area) of the glass panel can be increased as compared with the case where the ventilation device is installed below the upper rail. Further, the appearance can be improved, the deterioration of the heat insulation performance can be suppressed, and the workability at the time of assembly can be greatly improved.

  In addition, as shown in FIG. 6, when a ventilation device is incorporated in the upper rail 1, in general, in order to compensate for a decrease in strength due to the penetration of the indoor vent 2 and the outdoor vent 3, the reinforcing core 4 I am trying to install. The reinforcing core member 4 is made of, for example, a metal member having a predetermined length in the lateral direction, such as an L shape or a U shape, and connects the indoor side vent 2 and the outdoor side vent 3 of the upper rail 1. Is fixed to the partition 8 that divides the ventilation path 6 in the hollow portion 5 communicating with the inside and outside of the room and the shoji holding recess (swallowing portion) 7 that holds the glass panel with screws 9 from the lower surface side, and is L-shaped. One side 4a (or a U-shape) is installed along the partition 8, and the other side 4b is installed along the side wall (inner side wall 10) of the shoji holding recess 7.

Japanese Patent No. 4891128

  However, in a sash window in which a ventilation device is incorporated in the above-described conventional upper beam, since the indoor vent and the outdoor vent are provided on the upper beam, the partition of the hollow part is softened by heating in the event of a fire. The screws for screwing the reinforcing core material to the partition may come off, and the reinforcing core material may be deformed or fall off.

  Then, the softening of the partition and the dropping of the screws and the reinforcing core material occur in this way, so that the strength of the upper rail itself is remarkably lowered and the glass panel cannot be held, and as a result, there is a possibility that the fire prevention performance cannot be secured. .

  In view of the above circumstances, the present invention reliably prevents the reinforcing core from falling off in the event of a fire even when a ventilator is incorporated in a side wall such as an upper rail, and has fire prevention performance (heat insulation / smoke insulation / fire prevention). An object of the present invention is to provide a sash window that can ensure performance.

  In order to achieve the above object, the present invention provides the following means.

A reinforcing core material is disposed in the shoji holding recess, and a first thermal expansion refractory material that is heated and expands in a fire is attached to one surface forming the ventilation path of the partition. .

  In the sash window of the present invention, the second thermal expansion that is heated and expands in the event of a fire on the other surface forming the shoji holding recess of the partition and / or the reinforcing core member fixed to the other surface. It is desirable to have a refractory material attached.

  In the sash window of the present invention, by installing the first thermal expansion refractory material on one side of the partition that partitions the ventilation path and the shoji holding recess, the first thermal expansion refractory material is heated and expanded in the event of a fire. In addition, one surface of the partition or a screw for fixing the reinforcing core can be covered. As a result, the fire-proof performance of the first thermal expansion refractory material (thermal insulation, heat resistance, fire resistance, fire resistance, etc.) can prevent the partition from softening in the event of a fire, and the screws screwed to the partition can be removed. This prevents the reinforcing core from being deformed or dropped off.

  Therefore, in the sash window of the present invention, the softening of the partition and the prevention of falling off of the screw and the reinforcing core material can prevent holding the shoji such as a glass panel without deteriorating the strength of the recumbent itself. Thus, it is possible to suitably ensure fire prevention performance.

Further, in the sash window of the present invention, the second thermal expansion refractory material is also attached to the other surface forming the shoji holding recess of the partition and / or the reinforcing core material fixed to this other surface, The first thermal expansion refractory material and the second thermal expansion refractory material can protect the partition and screws from one side and the other side of the partition from heat during a fire.
Thereby, it is possible to more reliably prevent the partition from being softened in the event of a fire, and to prevent the reinforcing core member from being deformed or dropped due to a screw screwed to the partition being removed.
