BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a window body mounting structure in a window frame which constitutes a window mounted on a building.

[0002]

[Background Art] [Problems to be Solved by the Invention]
A wooden frame or the like has been used as the window frame fixed to the outer peripheral portion of the window body such that the outer peripheral portion of the window body is made of a glass plate or the like. However, wooden window frames are more prone to decay than rainwater, so they have difficulty in durability.
Since it burns easily, there was a problem in fire protection. Therefore,
In recent years, window frames made of metal or synthetic resin have been widely used.

As the inner peripheral surface of the window frame, various attachment structures for supporting and fixing the outer peripheral portion of the window body are adopted.
Generally, in the conventional window body mounting structure, a pair of fixing members are provided so as to project on both sides of the outer peripheral portion of the window body so as to fix the window body mounted on the opening surface of the window frame. I am letting you.

By the way, recently, from the viewpoint of disaster prevention, non-combustible buildings have been promoted, and in particular, in order to avoid burning, it is an important issue to prevent ignition due to flames or radiant heat approaching from the outside. There is. From this point of view, the window having the conventional window body mounting structure is not sufficient.

That is, recently, the size of the window body has been gradually increased, and the weight of the window has been increased accordingly. Therefore, the outside of the window body expands more than the inside of the window due to the heat received by the window in the event of an external fire, and the outside of the window is curved in a convex shape. In such a state, due to the weight of the window body, the upper side portion of the window body tends to separate from the upper side portion of the window frame, and a gap tends to occur between the upper side portion of the window body and the upper side portion of the window frame. In that case, no matter how incombustible the building and the window, the flame easily penetrates indoors through the gap between the window body upper side and the window frame upper side, and ignites the combustibles existing in the room. A secondary fire will occur on the indoor side, resulting in burning.

Therefore, according to the present invention, the window body is more firmly attached to the window frame to resist the thermal deformation stress of the window body in the event of a fire and suppress the generation of a gap between the window frame and the window frame. Accordingly, it is an object of the present invention to provide a window frame mounting structure for a window frame, which prevents the passage of flames through the gap.
