Description

  The present invention relates to a joinery including a synthetic resin window frame.

  A joinery including a synthetic resin window frame is known (see, for example, Patent Document 1). The window frame made of synthetic resin has a frame structure that forms an upper frame, a lower frame, a left vertical frame, and a right vertical frame. Each frame member is provided with a hollow portion along the longitudinal direction in order to increase rigidity, and the rail provided in the window frame and guiding the shoji is also provided with a hollow portion along the longitudinal direction.

  Since the synthetic resin window frame has low fire resistance, a shaped steel member including a rail is inserted into the hollow portion as a reinforcing member in the hollow portion, and the inserted reinforcing member is between the reinforcing members. It is joined or fixed to the housing via a metal member, and the reinforcing member remains even if the window frame melts due to a fire or the like. Further, some hollow portions are provided with a thermally expandable refractory material in the vicinity of a wall surface located on the opening side formed by the window frame.

  When installing the shoji for the sliding window, the so-called “Kandon” method is used. Therefore, the upper part of the shoji and the window frame are separated by the joinery in the summoning part of the shoji after installation. A gap that connects the two spaces is generated. For this reason, a windshield member made of synthetic resin that closes the gap is provided between the inner rail that guides the inner shoji and the outer rail that guides the outer shoji above the shoji summoning section. ing.

Japanese Patent Laying-Open No. 2005-351209

When the above-mentioned joinery is exposed to a flame due to a fire or the like and the window frame is melted together with the windshield member, the thermally expandable refractory material provided close to the wall surface located on the opening side is also heated, and the windshield member is melted. The thermally expandable refractory material foams in the space formed as described above. At this time, it is required that the space between the inner rail and the outer rail above the summing portion be closed more quickly and more reliably.
This invention is made | formed in view of this subject, The place made into the objective is to provide a fitting with higher fire prevention property.

  In order to achieve such an object, the joinery of the present invention has a first hollow portion along the longitudinal direction, and guides the inner and outer shojis, respectively, the upper end of the inner rail and the outer rail. A synthetic resin upper frame including a main body portion including a second hollow portion extending in a longitudinal direction on the connection portion including a connection portion connecting the upper ends of the first rail and the first rail of the outer rail. A metal rail reinforcing member provided in each hollow portion, and a metal rail disposed on the connecting portion and accommodated in the second hollow portion, and disposed on the outside of the inner rail and on the indoor side of the outer rail. It is a fitting characterized by having a member and a heating foam material provided in the second hollow portion.

  According to such joinery, when the upper frame is melted due to a fire or the like, the connecting portion is also melted, so that the metal member arranged on the connecting portion is lowered and provided in the second hollow portion. The heated foam material foams. For this reason, since the metal member is interposed between the inner rail and the outer rail, and the foamed heating foam material enters the gap between the inner rail, the outer rail, and the metal member, a fitting having higher fire resistance is provided. It is possible.

  In such a fitting, the inner sward and the outer sward have a smoke smoker engaged with each other at a summing unit, and at least one of the smoke scent of the inner kid and the smoke smoke of the outer sword One of them has a metal smoke reinforcement member, and the metal member is preferably located above the smoke smoke reinforcement member.

  According to such a joinery, when the connecting member is melted by the flame and the metal member descends, the metal member descends onto the smoke-reinforcing reinforcement member, and therefore, between the two spaces partitioned by the inner and outer shoji. It is possible to more reliably prevent the flame from penetrating.

In such a joinery, the rail reinforcing member is fixed to a connecting reinforcing member that is provided on the rail reinforcing member and connects to the housing,
The height of the metal member is preferably higher than the distance between the upper end of the smoke-reinforcing reinforcing member and the lower end of the connecting reinforcing member.

  According to such a joinery, since the height of the metal member is higher than the interval between the upper end of the smoke-reinforcing reinforcement member and the lower end of the connection reinforcing member, the connecting portion is melted by the flame and descends onto the smoke-return reinforcing member. The upper end portion of the metal member is positioned above the lower end of the connection reinforcing member. For this reason, even if a metal member descends on the smoke-reinforcing reinforcing member, it is supported from both sides by the connecting reinforcing member to which the inner rail and the outer rail are fixed. For this reason, it is possible to keep the lowered metal member between the inner rail and the outer rail.

  In this fitting, the connection reinforcing member is provided on each of the indoor side and the outdoor side of the metal member, and the connection reinforcing member is connected to a metal frame fixing member fixed to the frame. It is desirable that

  According to such a joinery, the connection reinforcing members connected to the metal frame fixing member fixed to the frame are provided on the indoor side and the outdoor side of the metal member, respectively. Even if the frame is melted, the connection reinforcing member remains on the indoor side and the outdoor side of the metal member. For this reason, when the connecting portion is melted, the metal member descends while being guided by the connection reinforcing member, so that the metal member can be lowered so as not to fall down.

  In this joinery, it is desirable that the metal member is provided along the inner rail and the outer rail, and is fixed to the upper frame at both end portions in the longitudinal direction.

  The inner rail and the outer rail are divided into two spaces separated from the inner shoji and the outer shoji at the summoning section. For this reason, when the metal member is fixed to the upper frame on both ends of the rail as in the above-mentioned joinery, the one fixing portion and the other fixing portion are located on different space sides. Become. For this reason, even if a flame is generated in one of the space sides and the fixed portion of the metal member in one space side is exposed to the flame and the upper frame melts, the fixed portion located on the other space side A metal member is held. For this reason, even if the fixed portion on one space side melts, the metal member descends on the one space side, and the metal member is placed on the smoke return reinforcing member at the summoning portion. It is possible to maintain.

  In this joinery, the main body portion has an upper surface portion that forms the second hollow portion and faces the connection portion, and the metal member has a facing portion that faces the upper surface portion, It is desirable that the heating foam material be provided between the upper surface portion and the facing portion.

  According to such a joinery, the heated foam material is opposed to the connecting portion disposed on the metal member, and is opposed to the upper surface portion that forms the second hollow portion, and the metallic member that is opposed to the upper surface portion. Since the heating foam material is provided between the two parts, the metal member is pressed downward when the heating foam material is heated and foamed. For this reason, it is possible to lower the metal member faster and more reliably, and to allow the heated foam material to enter between the inner rail and the outer rail.

For this reason, when the lower surface portion 24a is melted, the intermediate reinforcing member 13 is lowered by being guided by the outdoor reinforcing member 11 and the indoor reinforcing member 12, so that the intermediate reinforcing member 13 is lowered so as not to fall down. It is possible.

  The inner rail 25 and the outer rail 26 are divided into two spaces partitioned by the inner shoji 3 and the outer shoji 4 with the summoning section as a boundary. For this reason, when the intermediate reinforcing member 13 is fixed at both end portions of the upper frame 21 as in the joinery 1 of the present embodiment, one fixing portion and the other fixing portion are different from each other on the space side, That is, they are located on the indoor side and the outdoor side. For this reason, even if a flame is generated in one of the space sides and the fixed portion on one space side is exposed to the flame and melted, the intermediate reinforcing member 13 is held by the screw 15 located on the other space side. The For this reason, even if the fixed portion on one space side melts and the intermediate reinforcing member 13 descends on the one space side, the intermediate reinforcing member 13 reinforces smoke return at the summoning portion as shown in FIG. It is possible to maintain the state of being placed on the member 66.

  Further, the heating foam material 7 is opposed to the lower surface portion 24a that forms the central hollow portion 21c where the intermediate reinforcing member 13 is disposed, and the upper surface portion 24b that forms the central hollow portion 21c, and the intermediate surface that is opposed to the upper surface portion 24b. Since it is provided between the upper facing portion 13c of the reinforcing member 13, when the heated foam material 7 is heated and foamed, the intermediate reinforcing member 13 is pressed downward. For this reason, it is possible to lower the intermediate reinforcing member 13 faster and more reliably, and to allow the heating foam material 7 to enter between the inner rail 25 and the outer rail 26.

  In addition, the said embodiment is for making an understanding of this invention easy, and is not for limiting and interpreting this invention. The present invention can be changed and improved without departing from the gist thereof, and it is needless to say that the present invention includes equivalents thereof.
