Description

DETAILED DESCRIPTION OF THE INVENTION (Industrial field of application) The present invention mainly relates to an eaves which can be retrofitted in a building structure having a skeleton using an ALC plate.

(Prior Art) In general, eaves and entrances, windows, and other openings of a wooden house are provided with an eaves called a fog shield. This eaves, for example, prevents rainwater flowing down the wall on the upper floor from entering the room through the openings, and reduces the direct irradiation of direct sunlight into the room in the summer, thereby reducing the indoor environment. To prevent deterioration of indoor temperature and increase of indoor temperature. In the absence of this eaves, for example, when typhoons and other wind and rain are severe, rainwater is transmitted in the form of a water film from the wall surface, and the wind pressure penetrates into the room from the sash portion of the opening, significantly damaging the structure and degrading the building structure. It is what makes me.

On the other hand, from the viewpoint of the appearance design of the building structure, when there is no eaves, the outer wall surface becomes flat,
Since it lacks accents and individuality, it has no external features, and these tendencies are particularly noticeable in concrete-structured building structures.

(Problems to be solved by the invention) In recent years, however, in the case of a building structure of a concrete skeleton, it is used as an outer wall in order to shorten the construction period, facilitate the handling of construction members, and reduce costs. , ALC boards that are aerated concrete are often used. However, when the eaves are provided on the wall body of this ALC plate, it is easy to install it at the time of construction, but it is difficult to install it after the completion.

That is, when installing the eaves, the eaves are supported on the outer surface of the ALC plate by bolts that are inserted through the holes for connection opened in the ALC plate, and the inner side surface of the ALC plate is nut-fixed. This is because if a predetermined interior is provided on the inner side surface of the building structure after completion of the building structure, the interior material and the like must be removed once. In addition, opening a coupling hole in the ALC plate itself not only damages the location, but also causes water leakage.Besides, it requires construction work from the outside of the building, so a temporary scaffold is required. However, it is often technically difficult and very expensive in terms of cost.

Therefore, the present invention was devised in view of various existing circumstances such as the above, and even a building structure using an ALC plate has a sash frame installed in its opening. Even if it is retrofitted using parts, it can be easily installed, and it can be done by one-side construction from the inside of the building without using temporary scaffolding. Also, damage to exterior materials and water leakage after construction The purpose is to provide an eaves without the fear of.

(Means for Solving the Problems) In order to achieve the above-mentioned object, in the present invention, the left and right vertical frame portions of the predetermined sash frame 2 installed in the opening of the frame 1 of the building structure are installed as a frame.
