(Regarding the action of the fixing structure of the upper horizontal frame member)
Next, the operation of the fixing structure of the upper horizontal frame member 13 configured in this manner will be described. The action of the fixing structure of the upper horizontal frame member 13 is roughly divided into the action when a fire breaks out on the outdoor side of the room and the action when a fire breaks out on the indoor side of the room. Since they are substantially the same, only the action when a fire breaks out on the outdoor side of the room will be described below.

For example, when a fire breaks out on the outdoor side of the room in the fully closed state, the wooden support member 3 is exposed to the flames of the fire.

In this case, the support-side combustion-suppressing covering material 40 prevents the wooden support member 3 from burning. As a result, at least a part of the wooden support member 3 is burned, so that the fire can be prevented from spreading from the outdoor side of the room to the indoor side through the wooden support member 3 .

In addition, the connection side combustion suppression covering material 80 can prevent the connection portion 70 from being directly exposed to the flames of the fire, and suppress the conduction of the heat of the fire to the wooden support member 3 via the connection portion 70. can. As a result, it is possible to prevent the wooden support member 3 from collapsing because it is possible to suppress the deterioration of the durability of the wooden support member 3 due to the heat of the fire.

The third support-side connection piece 73c of 73 is brought into contact. After that, the plurality of connection-side fixing members 76 are fixed to the second support-side connection piece 73b via the second frame-side connection piece 72b, and are connected to the third frame-side connection via the third support-side connection piece 73c. It is fixed against piece 72c.

(Fixing method of frame member-Fixing method of upper horizontal frame member-Second covering step)
Next, the second covering step will be explained.

The second covering step is a step of covering the wooden support member 3 and the connecting portion 70 with the second support-side combustion-suppressing covering material 60 and the connecting-side combustion-suppressing covering material 80 after the connecting step.

Specifically, at the installation site, the entire viewing surface of the wooden support member 3 on the outdoor side of the room is covered by the integrally formed outdoor second support side combustion suppression coating 60a and the outdoor connection side combustion suppression coating 80a. After arranging the outdoor second support side combustion suppression coating 60a and the outdoor connection side combustion suppression coating 80a so that they are substantially covered and the entire exterior surface of the room on the outdoor side of the connection portion 70 is substantially covered, The outdoor second support-side combustion suppression covering material 60a is fixed to the wooden support member 3 with a fixture or/and an adhesive agent or the like. The indoor second support-side combustion suppression coating 60b and the indoor connection-side combustion suppression coating 80b integrally formed substantially cover the entire viewing surface of the wooden support member 3 on the indoor side of the room, and the connecting portion After arranging the indoor second support side combustion suppression coating material 60b and the indoor connection side combustion suppression coating material 80b so as to substantially cover the entire viewing surface of the room on the indoor side at 70, the indoor second support side combustion The restraining covering 60b is fixed to the wooden support member 3 by means of fasteners and/or glue or the like.

Therefore, when a fire breaks out around the fittings 1, the flames of the fire or the like will prevent the wooden structure from being damaged. The support member 3 can be prevented from burning and the frame member 15 can be prevented from being detached from the wooden support member 3, thereby reducing damage to the wooden support member 3 due to the fire. In addition, compared to the case where the connection part 70 is not provided, the mounting position of the frame member 15 and the wooden support member 3 can be easily adjusted when mounting the frame member 15, so that the mountability of the frame member 15 is improved. be able to.
