Subsequently, as shown in FIG. 13, the connection member 6 is fixed to the indoor facing surfaces of the mounting steel members 10 and the inner vertical frames 24 of the pair of windows with screws 6a and 6b.
After that, as shown in FIGS. 3 and 4, the fireproof board 7 is placed on the indoor side facing surface of the connecting member 6, and the fireproof board 7, the connecting member 6 and the mounting steel member 10 are tightened together with screws 701. fixed. Further, the inner cover member 9 is moved so as to cover the indoor side of the fireproof board 7 from the indoor side, and the inner cover member 9 is fixed to the connection member 6 .

According to this embodiment, the following effects are obtained.
The continuous window structure of this embodiment is arranged between one window portion 20 and the other window portion 20 provided in the opening portion 1a of the building, and the frame body 2 on the side of the one window portion 20 and the window portion 20 on the other side are arranged. A connecting member 6 having a hollow mounting steel member 10 connecting with a frame body 2 on the side, arranged on the indoor side of the mounting steel member 10, and a fireproof board 7 arranged on the facing surface of the connecting member 6 on the indoor side. The frame 2 on the side of one window 20 protrudes toward the frame 2 on the side of the adjacent window 20 and is fixed to the exterior side of the mounting steel 10 with screws 32a. The frame body 2 on the other window part 20 side protrudes toward the frame body 2 on the adjacent window part 20 side and faces the outdoor side of the mounting steel material 10. It has a projecting plate-like portion 244 fixed by a screw 32a. Therefore, the mounting steel member 10 is screw-fixed to the protruding plate-like portion 244 of the frame 2 on the one window portion 20 side, and is screw-fixed to the protruding plate-like portion 244 of the frame 2 on the other window portion 20 side. be. Therefore, there is no need to weld anchors or the like to the frame body 2 during construction. As a result, the continuous window structure can be easily constructed.

Further, in this embodiment, the first external member 3 fixed to the inner vertical frame 24 of the frame 2 of the window portion 20 on one side, and the first external member 3 arranged on the outdoor side of the first external member 3 a second external member 4 fixed to the .
Here, in order to realize the continuous window structure of the present embodiment, as described above, with the mounting steel member 10 arranged between the projecting plate-shaped portion 244 of the frame 2 and the fireproof board 7 in the direction of projection, The mounting steel material 10 is screw-fixed to one protruding plate-shaped portion 244 and the other protruding plate-shaped portion 244 of the adjacent window portion 20 . In this case, the gap in the direction of projection between the projecting plate-shaped portion 244 of the frame 2 and the fireproof board 7 tends to become smaller, and the gap in the direction of projection between the projecting plate-shaped portion 244 of the frame 2 and the fireproof board 7 Since it is necessary to dispose the mounting steel material 10 in the vertical direction, the dimension of the mounting steel material 10 in the prospective direction tends to be small. If the size of the mounting steel material 10 in the projected direction is reduced, the strength tends to be weak against the force acting on the mounting steel material 10 in the projected direction, and problems such as insufficient wind pressure resistance and increased deformation in the event of a fire occur. may occur.
On the other hand, in the present invention, by providing the first external member 3 and the second external member 4, the first external member 3 and the second external member 4 can function as strength members, and the mounting steel material 10 It is possible to reinforce the strength against the force acting in the expected direction.

In addition, in the present embodiment, the water stop material 45 arranged between the second external member 4 and the frame 2 on the one window portion 20 side, and the second external member 4 and the other window portion 20 side and a water stop material 45 arranged between the frame 2 . As a result, simply by fixing the second external member 4 to the first external member 3, the water stop material 45 can be pressed against the outdoor side facing surface 242a of the outdoor side facing wall portion 242 of the inner vertical frame 24. , the watertightness between the outer decorative cover 5 and the inner vertical frame 24 can be improved.

Further, in this embodiment, the first external member 3, the protruding plate-shaped portion 244 of the window portion 20 on one side, and the mounting steel material 10 are fastened together and fixed by the screws 32a. As a result, the first external member 3, the protruding plate-shaped portion 244 of the window portion 20 on one side, and the mounting steel material 10 can be firmly fixed. Therefore, the mounting strength of the mounting steel material 10 can be improved.

Moreover, in this embodiment, the 2nd exterior member 4 is arrange|positioned in the position where at least one part overlaps with the 1st exterior member 3 in the prospective direction so that the outdoor side of the 1st exterior member 3 may be covered. As a result, at least a portion of the second external member 4 overlaps the first external member 3 in the projection direction, so that the strength against the force acting in the projection direction of the mounting steel member 10 can be improved.

Further, in this embodiment, an outer decorative cover 5 is arranged on the outdoor side of the second external member 4 so as to cover the outdoor side of the second external member 4 and is fixed to the second external member 4 . Therefore, since the outer decorative cover 5 covers the outdoor side of the second external member 4, joints and screws between the members are not visible, and the design can be improved.

Further, in this embodiment, the second external member 4 is provided with a hook engaging member 44 on the outdoor side viewing surface, and the outer decorative cover 5 protrudes from the indoor side viewing surface and extends vertically. The mounting projecting piece 53 has an extending mounting projecting piece 53 , and the mounting projecting piece 53 continues to the notch 54 formed in the middle of the vertical direction, and the end of the notch 54 and projects to the side of the mounting projecting piece 53 . and an inner engaging projection 532 extending in the vertical direction. An inner engagement projection 532 can be engaged with the hook engagement member 44 . This makes it possible to easily attach the outer decorative cover 5 to the second external member 4 .

In the present embodiment, the exterior surface 10a of the mounting steel member 10 is arranged substantially on the same plane as the exterior surface 1b of the building frame 1 forming the opening 1a of the building. As a result, the protruding plate-like portion 244 of the inner vertical frame 24 of the frame 2 of the window portion 20 is aligned with the exterior surface 10a of the mounting steel member 10 and the exterior surface 1b of the upper and lower members of the frame 1. can be placed along Therefore, by arranging the protruding plate-shaped portion 244 of the inner vertical frame 24 of the frame 2 along the exterior surface 10a of the mounting steel 10 and the exterior surface 1b of the frame 1, the normal The continuous window 100 of the present embodiment can be easily attached to the building frame 1 in the same manner as when the window frame is attached to the projected surface of the building body.

Although the preferred embodiments of the present invention have been described above, the present invention is not limited to the above-described embodiments and can be modified as appropriate.
For example, in the above-described embodiment, the first external member 3 is fixed to the projecting plate-shaped portion 244 of one frame 2, but is not limited to this, and is fixed to the projecting plate-shaped portion 244 of the other frame 2. Alternatively, it may be fixed to both the projecting plate-shaped portion 244 of one frame 2 and the projecting plate-shaped portion 244 of the other frame 2 .
