Description

  According to the present invention, an airtight panel formed by fixing a structural face material to an indoor side surface or an outdoor side surface of a frame body constituted by an upper frame, a lower frame, a left frame, and a right frame is fitted into an opening formed by a shaft assembly. The present invention relates to a hermetic device between a hermetic panel body and a shaft assembly in a wall device of a wooden building used for preventing air flow through a gap generated when it is inserted.

  An airtight panel formed by adhering a structural face material to one side of a frame composed of an upper, lower frame and left and right frames is combined with a pair of adjacent columns and horizontal members such as girders and trunk differences. A wall device for a wooden building, which is configured by being fitted into an opening formed in this manner, is known, but this known structure generally has a face material disposed on the outdoor side so as to face the airtight panel body. Thus, an air layer (sealed chamber) is provided between the face material and the airtight panel body to enhance the heat insulating effect (for example, Patent Documents 1 and 2).

Between the assembled materials, an airtight material is interposed, and first and second airtight lines are provided along the inner peripheral surface.

  According to the present invention, the airtight panel body formed by fixing the structural face material to the indoor side surface or the outdoor side surface of the frame body constituted by the upper, lower frame and the left and right frames, and the opening portion constituted by the shaft assembly material. It is possible to reliably prevent aeration through the gap that occurs when it is fitted in. Therefore, the sealed room formed on the outdoor surface side or the indoor side surface of the hermetic panel body can function as a heat insulating air layer, and a wall device for a wooden building having an excellent heat insulating effect can be provided.
