(Effect of the opening device of the present embodiment)
The opening device of this embodiment is fixed to the outer wall of the building by means of a four-circumference base material. In addition to being adhesively fixed to the waterproof layer, the upper base material and vertical base material are screwed and fixed to the outer wall, so that it can be firmly fixed to the outer wall without complicating the construction work. It can be stably fixed over four circumferences.

The opening device of the present embodiment is a dry sealing material that adheres and fixes to the building side face of the base material even if the outer wall surface is not flush because the outer wall material is not installed under the outer wall to which the base material is attached. By laminating and adjusting the thickness, it is possible to adhere and fix without gaps over the four circumferences, and it is possible to improve watertightness by simple construction.
In addition, by laminating one kind of dry sealant to form sealants with different thicknesses, there is no need to prepare many kinds of dry sealants, and the management of parts can be simplified.

Since the opening device of this embodiment can be fixed to the outer wall without using the frame material of the fittings F placed in the opening, it is not affected by the type of fittings F placed in the opening. This makes it easier to manage members and improves workability.

In the opening device of this embodiment, the screwing portion for firmly fixing the base material to the outer wall is arranged on the inner circumference of the dry sealing material that watertightly seals the gap between the base material and the outer wall. Corrosion can be suppressed and strong fixation can be maintained over a long period of time.

-Other embodiments-
The frame material of the shutter device of the present embodiment is attached to each base material with screws or the like, but the method of fixing the attached building frame to the base material is not limited.

The dry sealing material adhesively fixed to the indoor facing surface of the backing material 3 of the opening device of the present embodiment adjusts the expected size of the sealing material by laminating dry sealing materials having a predetermined thickness. , the estimated size may be adjusted by preparing dry sealing materials having different thicknesses.

The upper base material of the base material 3 of the opening device of this embodiment is composed of two members, an upper base material (upper) 311 and an upper base material (lower) 312. It does not have to be composed of members, and each base member may be formed of one or a plurality of members depending on the building attachment frame attached to the outer wall of the building.

The opening device is not limited to the shutter device, and is not limited at all as long as it is attached to the outer wall of the building.
