Description

  The present invention relates to a joinery, and more particularly, to a joinery including an external shoji and an internal pouch such as a sliding window and a sliding window.

  Recent fixtures are required to have higher fire resistance. For example, in the joinery described in Patent Literature 1, a steel reinforcing member is disposed inside a hollow frame, and the portion of the reinforcing member that faces the shoji of the shoji has thermal expansion properties. The material is arranged. According to this joinery, when the frame is exposed to a flame due to a fire or the like and the frame has a hole, the refractory material expands due to thermal expansion, filling the gap between the frame and the shoji of the shoji. It will be possible to block the passage of smoke.

  By the way, when the joinery becomes a high temperature state due to a fire or the like, thermal expansion (thermal elongation) occurs along the surface direction in the face material of the shoji. Here, in a joinery equipped with an external shoji placed outside and an interior shoji placed indoor such as a sliding window or a single-drawing window, the summoning cage is locked with the crescent. In addition, since the thermal expansion of the face materials is limited to each other, the summons of the shoji are twisted or curved. As a result, there is a possibility that a through-hole is formed between the end portion of the summoning bowl and the vertical frame (support frame) of the opening frame, and there is a problem that flames and smoke blow out through the through-hole to the inside and outside of the room.

  Further, the portion of the vertical frame in which the outer frame is disposed is not exposed to the outside because it is covered with the outer frame when the opening frame is closed. However, the portion on the outer side of the vertical frame in the vertical frame is exposed to the outside even when the opening frame is closed. Therefore, when a fire occurs from the outside of the room, the portion exposed to the outside in the vertical frame is directly exposed to the high heat of the flame, which may cause a through-hole.

  In view of the above circumstances, an object of the present invention is to provide a joinery that can prevent a decrease in fire resistance due to the provision of an external shoji and a internal shoji.

  In order to achieve the above-mentioned object, a joinery according to the present invention is a joinery including an inward side inner shoji and an outer side shoji between a pair of support frames constituting an opening frame.

A frame reinforcing member having a frame protruding plate portion that is bent so as to protrude from the positioned edge portion, and further facing the prospective surface of the frame substrate portion and the inward side of the frame protruding plate portion. The heating expansion material is disposed on each of the found faces, and when the opening frame is closed in the pair of support frames, the portion facing the end surface of the sumo fold of the shoji is located on the prospective surface of the support frame. The summing board portion arranged along the inside of the summing board portion. A summing reinforcing member having a summing protruding plate bent so as to protrude from the edge to be bent and a summing sealing portion bent outward from the protruding end of the summing protruding plate. The heating expansion material is disposed on the prospective surface of the summing substrate portion, the finding surface facing outward of the summing protruding plate portion, and the prospective surface facing the shoji of the summing sealing portion, respectively. It is characterized by that.

  According to the present invention, when the opening frame is closed in the support frame due to the expansion of the heat expansion material disposed in the frame reinforcing member, the portion that is on the outer side from the inner shoji is covered, and the summing reinforcing member The space between the end of the summoning bowl and the support frame of the opening frame is covered by the expansion of the heat-expanding material disposed, thereby preventing the occurrence of a through-hole in each.

  Further, according to the present invention, in the joinery described above, when the opening frame is closed in the pair of support frames, the support is provided at a part facing a support rod of the outer panel arranged in parallel to the support frame. A heat expansion material is disposed on the prospective surface of the frame.

  According to the present invention, the gap between the support frame of the opening frame and the support rod of the shoji can be closed by the expansion of the heat expansion material disposed on the support frame without requiring a reinforcing member.

  Further, according to the present invention, in the joinery described above, the frame protruding plate portion of the frame reinforcing member and the summing protruding plate portion of the summing reinforcing member are supported by a support fin portion protruding from the prospective surface of the support frame. It was made to be characterized.

Will be able to. Moreover, since the heating expansion material 114 is disposed on the inside of the frame substrate portion 141 and the frame protruding plate portion 142 in the frame reinforcing member 140, these heating expansion materials 114 are in contact with each other. The vertical frame 13 can be reliably covered. Thereby, the prospective surface exposed to the outside in the vertical frame 13 is not directly brought into a high temperature state by the flame, and there is no possibility that a through hole is formed.

  Further, in the above-mentioned joinery, in a state where the lower arm 22 of the outer shoji 20 and the upper arm 31 of the inner shroud 30 are locked by the crescent 35, the joinery becomes a high temperature state due to a fire or the like, and the face materials 24, 34. When the heat elongates and the vertical eaves 23 and 33 are heated, the lower eaves 22 of the outer shoji 20 are twisted or deformed, and penetrated between the end of the lower eaves 22 of the outer shroud 20 and the vertical frame 13. May cause a mouth. However, according to the joinery described above, the space between the end portion of the lower rod 22 and the vertical frame 13 is covered by the expansion of the heating expansion material 115 disposed on the summing reinforcement member 150. Even if a twist or a curved deformation occurs, it is possible to prevent a situation in which a through-hole is generated between the vertical frame 13.

  As a result, according to the joinery described above, even when exposed to a high temperature state from the outside due to a fire or the like, there is no through-hole through which flames and smoke blow out, and the fire resistance is reduced. There is no fear of inviting a situation to do.

  In addition, according to embodiment mentioned above, although the single-sided window which arrange | positioned the inner side shoji 30 indoors so that sliding up and down with respect to the opening frame 10 was illustrated, this invention is an inner shoji and an outer shoji. It is also possible to apply to other fittings such as sliding windows in which inner and outer shoji slides up and down and sliding windows in which inner and outer shoji slides left and right respectively. .
