Description

[0001]
BACKGROUND OF THE INVENTION
The present invention relates to a connecting structure in which a composite window frame in which a resin frame is disposed on a room-side exposed portion of a metal frame is connected at a corner portion, and more particularly, two composite window frames are connected in a vertical manner. It is related with the corner part connection structure of a composite window frame.
[0002]
[Prior art]
Currently, so-called continuous windows are used in various buildings in which window frames are arranged in a horizontal direction with a metal frame interposed therebetween. As a window frame used for the continuous window, a composite window frame having a resin frame at the indoor side exposed portion thereof is used for a window frame made of a metal frame such as an aluminum sash. This is because the interior of the metal frame is covered with a resin whose thermal conductivity is extremely lower than that of metal, thereby improving the heat insulation of the sash window and suppressing the condensation on the indoor side. This is to improve the interior feeling of the indoor side by eliminating the coolness and providing the unity with the wall decoration on the indoor side.
[0003]
In such a continuous window, for example, as shown in Patent Document 1, a sealing material made of a resin material is attached to the side of a vertical room to improve heat insulation and design. However, when connecting each composite window frame with a predetermined angle, a problem arises in attaching the closing material. That is, such a composite window frame usually forms an angle piece on the indoor side of the resin frame and covers the four sides of the indoor side only with the resin material in order to improve the heat insulation on the indoor side. When the window frame is continuously provided with an angle, the angle piece also has an angle inside, and the angle piece interferes and the closing material cannot be attached from the front after the window frame is continuously provided. . In this case, it is possible to attach the closing material by sliding it from above, but the work becomes complicated, and it is difficult to replace the once-attached closing material.
[0004]
As a solution to such a problem, there is a connection structure described in Patent Document 2, for example. In the connection structure described in this document, a hollow body having a substantially triangular cross section made of a resin material and two linkage bodies having a substantially L-shaped cross section made of a resin material are provided on a vertical indoor side surface. A closing material is installed. By adopting such a configuration, even if each composite window frame is continuously provided with an angle, it is possible to attach the closing material from the front to the interior of the vertical room, and it is also possible to replace the closing material. .

In this way, since the closing material 20 is attached to the bending recess 60, and the closing material 20 and the angle pieces 51 and 51 of the resin vertical frames 43 and 43 are made continuous, the bending recess 60 is closed. The connection strength at the corners is ensured, and the overall heat insulating properties of the front window 1, the side windows 2, 2 and the stand 10 that are provided in a row are maintained. In addition, since the resin closing material 20 and the angle pieces 51 and 51 of the resin vertical frames 43 and 43 are continuous, the overall design of the indoor side is unified.
Further, the closing material 20 is composed of a main closing material 21 and a secondary closing material 22, and the vertical engaging portion 21 a of the main closing material 21 is engaged with the closing material engaging portion 16 provided on the vertical 10. Are attached to the bent recess 60, and the engaging portion 22a of the sub-blocking material 22 is engaged with the engaged portion 21b of the main closing material 21 to be attached to the bent recess 60, thereby reducing the number of parts and facilitating the mounting operation. Thus, the number of mounting steps is reduced, the cost is reduced, and the closing material 20 can be easily replaced. Furthermore, since the covering portions 21d and 22c that cover the angle piece 51 and are continuous with the angle piece 51 are formed at the end portions of the main closing material 21 and the auxiliary closing material 22, the interior design is further improved. is doing.
