Description

  The present invention relates to a joinery.

  In recent joinery, there is one in which frame constituent members such as eaves members and frame members for holding a face material are formed of resin. The frame component member has a hollow portion along the longitudinal direction inside each of the frame component members, and is configured in a rectangular frame shape by joining ends to each other. Specifically, the end surfaces of the frame constituent members are configured to have inclined surfaces, for example, 45 ° inclined surfaces, and are joined to each other using a joining means such as thermal welding. In this type of joinery, the frame components are superior in heat insulation compared to those formed of a metal such as aluminum or aluminum alloy, so that, for example, condensation is prevented even when there is a temperature difference between indoors and outdoors. There is an advantage (see, for example, Patent Document 1 and Patent Document 2).

  On the other hand, the frame constituent member formed of resin has a lower melting point than that of 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 relatively easily. For this reason, conventionally, a reinforcing member made of a metal such as iron or stainless steel is disposed in the hollow portion of the frame constituent member. The ends of the reinforcing members are connected to each other by a connecting member formed in an L shape. According to such a joinery, the reinforcing member remains even in a high temperature state, so that it is possible to prevent a situation where the face material falls off.

  Furthermore, the conventional joinery is also provided with a fire expansion property improved by sticking a heat expansion material to the surface of the reinforcing member. In this joinery, the hollow portion of the frame component member is blocked by the heat-expandable material that expands when it reaches a high temperature state, and it is possible to prevent a situation where the interior and the exterior are penetrated (for example, (See Patent Document 3).
