Description

  TECHNICAL FIELD The present invention relates to a holding structure for a face material and a fitting, and more particularly to a holding structure and a fitting suitable for holding a face material provided with a glass panel.

  Some joinery uses resin-made thing as face material holding members, such as a gutter member and a frame member which hold face materials provided with a glass panel. In this type of joinery, since the heat insulating property is improved as compared with the case where the face material holding member is formed of a metal such as aluminum or aluminum alloy, for example, condensation is prevented even when the temperature difference between the inside and outside of the room is large. There are advantages such as. On the other hand, resin has a lower melting point than metal. Therefore, when the temperature becomes high, such as when a fire breaks out, there is a risk of causing problems such as the face material falling off easily.

  For this reason, conventionally, in order to prevent the face material from falling off even in a high temperature state, a reinforcement member made of a metal such as iron or stainless steel is provided inside the face material holding member. (For example, refer to Patent Document 1). According to this fitting, even if a fire occurs, there is no fear that the reinforcing member disappears, and the situation where the face material falls off can be prevented. In addition, there is also provided one in which a heat-resistant glass stopper is provided at the peripheral edge of the face material to prevent the flame from coming off (for example, see Patent Document 2).

It is a part arrange | positioned so that it may cover between the end surface of the face material 24 with a clearance gap. As is apparent from the drawing, the face material cover portion 43 is inclined so that the distance from the inner surface of the face material 24 gradually decreases from each extending end portion toward the end surface of the face material 24. . That is, a gap reaching the end surface of the face material 24 is greatly opened between the extending end of the face material cover 43 and the inner surface of the face material 24.

  In the present embodiment, the fire protection member 40 disposed on the inner cover portion 21C of the upper collar member 21 is formed of steel, and the inner cover portion 22C of the lower collar member 22 and the inner cover of the vertical rod member 23 are formed. Each of the fire prevention members 40 disposed in the portion 23C is formed of an aluminum alloy. This is because the flame tends to move upward at the time of a fire, and the upper flange member 21 may be exposed to a higher temperature than the other flange members 22 and 23, so it is disposed in the inner cover portion 21C. A steel material having a melting point higher than that of the aluminum alloy is used for the fire prevention member 40.

  In the joinery configured as described above, since the eaves members 21, 22, and 23 are formed of resin, heat insulation is improved as compared with those formed of metal such as aluminum or aluminum alloy. There are advantages such as prevention of condensation even when the temperature difference is large. Moreover, the reinforcing hollow portions 21b, 22b, and 23b of the flange members 21, 22, and 23 are provided with a metallic reinforcing member 30 having a melting point higher than that of the resin, and the glass stopper 24d is screwed to the reinforcing member 30. Therefore, it is possible to prevent the face material 24 from falling off even when a fire occurs. Further, since the heating expansion material 60 is provided on the reinforcing member 30, the reinforcing hollow portions 21b, 22b, and 23b of the flange members 21, 22, and 23 are blocked by the expanded heating expansion material 60 when a fire occurs. Thus, it is possible to prevent a situation where the interior and the exterior are penetrated.

  Here, according to the joinery described above, the reinforcing base portion 31 of the reinforcing member 30 is provided with the inclined extending portion 31a having an inclination angle of 45 °, so that the reinforcing member 30 has as little gap as possible between them. Can be joined to each other, which is advantageous in terms of fire prevention performance. Moreover, the orthogonally extending portion 31 b is provided so as to extend along the direction orthogonal to the longitudinal direction of the reinforcing base 31 at the portion where the heat expansion material 60 is attached to the reinforcing base 31. Therefore, even when the long heating expansion material 60 is applied, it suffices to always cut along the direction orthogonal to the longitudinal direction, and an unnecessary portion is not generated, so that the yield is improved. Furthermore, since the width of the orthogonally extending portion 31b matches the width of the heating expansion material 60, positioning work becomes extremely easy when the heating expansion material 60 is attached, and mistakes in the attaching location can be prevented. Is possible.

  On the other hand, with respect to the face material 24 of the shoji 20, the fire prevention member 40 is disposed in the hollow portions 21 c, 22 c, 23 c of the eaves members 21, 22, and 23, and the face material 24 from the inner surface of the face material 24 in the prospective direction. Since it covers the space between the end surfaces of the frame with a gap, there is no fear that a through-hole is formed in the joinery even if the eaves members 21, 22, and 23 are melted or burned out, and the fire resistance can be improved. Moreover, the face material cover 43 that covers the space between the inner surface of the face material 24 and the end face of the face material 24 is gradually increased from the individual extended end portions toward the end face of the face material 24. It is inclined so that the interval decreases. Therefore, when the center part of glass panel 24a, 24b provided in the face material 24 became a high temperature state, the heat can reach a peripheral part, it prevents that a big temperature difference arises, and the glass panel 24a, 24b can prevent thermal cracking. Further, as the fire prevention member 40, a frame facing portion with respect to the fire prevention base 41 having a flat plate shape along the partition walls 21d, 22d, and 23d between the reinforcing hollow portions 21b, 22b, and 23b and the hollow portions 21c, 22c, and 23c. 42 and the face material cover portion 43 are applied so as to bend toward the indoor side, respectively, so that the portions constituting the indoor side finding surface and the fireproof member 40 in the flange members 21, 22, and 23 are applied. There is almost no contact part with. Thereby, there is no possibility that the fire prevention member 40 may impair the heat insulation of the eaves members 21, 22, and 23.

  In the above-described embodiment, the vertical sliding window is exemplified as an application target. However, the present invention is not necessarily limited to the vertical sliding window, and can be applied to other fittings such as a fitting window. It is. When applied to a fitting window, the face material holding member may be a frame member.
