Further, a receiving portion 6d for holding the heat-resistant glass 2a is formed on the side surface (right side surface) opposite to the mullion 4. As shown in FIG.

Similarly, the second connecting frame 7 has an outer surface portion 7a on the outdoor side and an inner surface portion 7b on the indoor side. A receiving portion 7d for holding the heat-resistant glass 3a is formed on the side surface (left side surface) opposite to the mullion 4 from the engaging portion 7c. 4, the estimated dimension L1 of the first connecting frame 6 is designed to be larger than the estimated dimension L2 of the second connecting frame 7. As shown in FIG.

As shown in FIG. 3, the mullion 4 includes a mounting steel member 9, a fireproof coating 10 disposed on the indoor side (back side) of the mounting steel member 9, and a connecting member that connects the mounting steel member 9 and the fireproof coating 10. 11. The mounting steel member 9 is a vertically elongated steel member formed into a hollow rectangular shape by opposing two U-shaped steel members. An engaging member 8 is welded to each side surface 9a of the mounting steel member 9, and a welded portion 9b is formed therebetween. The engaging member 8 engages the ends of the open engaging portions 6c and 7c of the first connecting frame 6 and the second connecting frame 7 at the inner and outer ends so as to sandwich the ends in the left-right direction. A first connection frame 6 and a second connection frame 7 are connected to the steel member 9 .

The connection between the mounting steel material 9 and the first and second connection frame bodies 6 and 7 is not limited to that via the welded engaging member 8 . For example, as shown in FIG. 8, connecting steel members 8a each made of steel are arranged between the frames 6 and 7 and the mounting steel member 9, and the connecting steel members 8a and the bottoms of the receiving portions 6d and 7d are screwed. The mounting steel material 9 and the first and second connection frames 6 and 7 may be connected by screwing the side surfaces 9a of the mounting steel material 9 and the connecting steel material 8a. Alternatively, the mounting steel member 9 and the frames 6 and 7 may be directly screwed and connected. In these cases, welding is not required and workability is excellent.

The fireproof coating 10 is a fireproof material made of a calcium silicate plate, and is configured so that both right and left ends thereof overlap end portions of the first panel body 2 and the second panel body 3 on the mullion 4 side in a front view. The connection member 11 is a vertically elongated metal member having a substantially letter-shaped configuration in a plan view with a flat plate surface portion 11a and side surface portions 11b extending from both right and left ends of the flat plate surface portion 11a toward the interior of the room. .

The inner cover 13 prevents the fireproof coating 10 from being exposed inside the room.

The right and left ends of the flat plate surface portion 11a of the connection member 11 are screwed in surface contact with the inner surface portion 6b of the first connecting frame 6 and the inner surface portion 7b of the second connecting frame 7 . As a result, the first connecting frame 6 and the second connecting frame 7 are attached to the mullion 4 such that the inner surface portions 6b, 7b are substantially at the same position in the inner and outer directions (projection direction). Therefore, the outer surface portion 6a of the first connecting frame 6 is arranged at a position that protrudes from the outer surface portion 7a of the second connecting frame 7 by L1-L2 toward the outside of the room.

In this way, when connecting the first panel body 2 and the second panel body 3 as fire prevention equipment, the inner surface portions 6b and 7b of the first and second connection frame bodies 6 and 7 are aligned with the fireproof coating 10 side. is desired. Therefore, if the frames 6 and 7 having different estimated dimensions are connected by the mullion 4, the inner and outer positions of the outer surfaces 6a and 7a of the frames 6 and 7 will be different.

Therefore, a spacer 14 is attached to the outer surface portion 7a of the second connecting frame 7 and has an outer surface portion 14a arranged at substantially the same position as the outer surface portion 6a of the first connecting frame 6 in the inner-outward direction. The spacer 14 is made of the same aluminum material as the first connecting frame 6 and the second connecting frame 7, and is configured by engaging the first spacer member 15 and the second spacer member 16, and extends in the inward and outward directions L1-L2. has a width of Therefore, as shown in FIG. 4, the spacer 14 is arranged such that the outer surface portion 14a is substantially at the same position as the outer surface portion 6a of the first connecting frame 6 in the inner-outer direction. As a result, the outer surface portion 14a of the spacer 14 is given an appearance as if it were the outer surface portion 7a of the second connecting frame 7 of the second panel body 3. It will appear that the positions of the inner and outer directions of 7a are aligned.

As shown in FIGS. 5 and 6, the first spacer member 15 includes an outer surface portion 15a that constitutes the outer surface portion 14a of the spacer 14, and a right side surface portion that extends from the end portion of the outer surface portion 15a on the side of the mullion 4 toward the interior of the room. 15b, and a left side portion 15c that extends indoors from the end on the side opposite to the mullion 4 of the outer surface portion 15a and contacts the outer surface portion 7a of the second connecting frame at the end portion on the indoor side. ing. At the indoor-side end of the right side surface portion 15b, an engaging protrusion 15d that protrudes toward the right side (the side of the mullion 4) and is fitted into an engaging piece 16b of a second spacer member 16, which will be described later, and the interior of the spacer 14 A receiving portion 15e that protrudes toward the left side, which is the side, and is screwed integrally with the second spacer member 15 is formed.

The indoor end of the left side surface 15c of the first spacer member 15, which abuts on the left end of the outer surface 7a of the second connecting frame 7, is a mounting end 15f that holds the water stop material 17. It has a water material holding portion 15g. The water stop material holding portion 15g is positioned inside the spacer 14 of the mounting end portion 15f, and is open on the interior side so that the water stop material 17 can be filled and held therein. The held water stop material 17 comes into contact with the outer surface portion 7a of the second connecting frame 7 from the outdoor side, so that the water stop performance is exhibited. Further, a screw receiving portion 15h is formed inside the spacer 14 of the left side portion 15c. The screw receiving portion 15h is provided to receive a screw when connecting with the upper spacer 24 attached to the upper frame 3d of the sash frame 3b of the second panel body 3 in the left-right direction, as will be described later.

The second spacer member 16 is engaged by fitting the flat plate portion 16a forming the inner surface portion 14b of the spacer 14 and the engaging protrusion 15d of the first spacer member 15 provided at the right end portion of the flat plate portion 16a. It has a U-shaped engaging piece 16b that can be engaged, and an inverted L-shaped pressing part 16c that is provided at the left end of the flat plate part 16a and presses the water stop material holding part 15g toward the indoor side. there is By pressing the water-stopping material holding portion 15g by the pressing portion 16c, the held water-stopping material 17 is pressed against the outer surface portion 7a of the second connecting frame 7 more strongly. The water stop performance between the frame body 7 is improved.

Further, the second spacer member 16 has a protrusion 16d that abuts on the right side surface of the second connecting frame 6 on the outside of the room and protrudes from the flat plate portion 16a toward the inside of the room. By abutting the projection 16d on the second connecting frame 7, the positioning of the spacer 14 is facilitated. Moreover, the length from the protrusion 16d to the left end of the spacer 14 is equal to the lateral length of the outer surface portion 7a of the second connection frame 7, so that the protrusion 16d contacts the second connection frame 7. The spacer 14 and the second connection frame 7 are connected flush with each other on the side surface (left side surface) opposite to the mullion 4 when they are positioned.

A method of attaching the spacer 14 to the second connection frame 7 is as follows. First, the flat plate portion 16a of the second spacer member 16 is attached to the outer surface portion 7a of the second connection frame 7 in a state where the protrusion 16d of the second spacer member 16 is brought into contact with the second connection frame 7 and positioned. make surface contact. In this state, the first screw 18 is used to screw the flat plate portion 16a to the outer surface portion 7a from the outdoor side. After that, the engagement projection 15d of the first spacer member 15 is fitted into the engagement piece 16b of the second spacer member 16 to engage with it, and the water stop material holding portion 15g holding the water stop material 17 is pressed. 16c into which it is press-fitted. In this state, the receiving portion 15e of the first spacer member 15 and the right end portion of the flat plate portion 16a of the second spacer member 16 are screwed with the second screw 19 from the inside of the room. When attached in this manner, both the first screw 18 and the second screw 19 are covered by the outer surface portion 15a of the first spacer member 15, so that the structure is such that they are not exposed to the outside.

The mullion 4 further has an outer surface portion 20 attached to the outdoor end of the mounting steel member 9 . The outer surface part 20 includes an outer convex-shaped outer surface member 21 whose outdoor side is open in a plan view, and an outer cover 22 that covers the outdoor side of the mullion 4 on the outdoor side of the outer surface member 21. ing. The outer surface member 21 has a wide width portion 21a on the outdoor side that protrudes to the right and left from the outer surface portion 6a of the first connecting frame 6 and the outer surface portion 14a of the spacer 14 and extends to the right and left, while a narrow portion on the indoor side. The inner surface portion of 21b is screwed to the outer surface portion of the mounting steel material 9. As shown in FIG. Further, the external cover 22 extends laterally beyond the wide portion 21a of the external surface member 21 to cover the outdoor side of the mullion 4, and when viewed from the outdoor side, the external surface portion 6a, The outer surface portion 7a of the second connecting frame 7 and the end portion of the outer surface portion 14a of the spacer 14 on the mullion 4 side are overlapped with each other. As a result, the connection portions between the connection frames 6 and 7 and the mullion 4 are not visible from the outside of the room, and the appearance is excellent. Caulking material 23 is filled between the outer surface portion 6a of the first connecting frame 6, the outer surface portion 14a of the spacer 14, and the laterally extending portions of the outer cover 22, respectively. The caulking material 23 is also designed not to be visually recognized from the outside by the outer cover 22 extending to the left and right.

In addition, such a structure of the mullion 4 is not limited to the case of connecting the first connecting frame 6 and the second connecting frame 7 having different projected dimensions, but can also be used when the projected dimensions are the same. For example, when connecting the first panel body 2 (that is, the first connection frame body 6) on both the left and right sides, as shown in FIG. One connection frame 6 can be connected. On the other hand, when the second panel body 3 (that is, the second connection frame body 7) is connected to both the left and right sides, the shape of the outer surface portion 40, particularly the shape of the outer surface member 41 is modified as shown in FIG. By adopting this, each second connection frame 7 can be connected without using the spacer 14 . In this case, a common outer cover 22 can be adopted. The outer surface member 41 has a narrow portion 41b whose inner and outer lengths are shorter than those of the outer surface member 21 of the present embodiment. However, it is also possible to connect the second connection frame 7 to which the spacer 14 is attached to the mullion 4 having the same shape as that of the present embodiment.

A spacer 14 is attached to the outer surface of the left vertical frame 3c of the sash frame 3b of the second panel body 3 in the same manner as the second connecting frame body 7 (see FIGS. 1 and 2). Furthermore, an upper spacer 24 having the same cross-sectional shape as the spacer 14 is attached to the outer surface of the upper frame 3d of the sash frame 3b in the lateral direction (see FIGS. 1 and 7). Left and right end portions of the upper spacer 24 are screwed to side portions of the spacer 14 . At this time, a screw is screwed into the screw receiving portion of the upper spacer 24 (corresponding to the screw receiving portion 15e of the spacer 14) from the inside of the spacer 14. As shown in FIG. As described above, the spacers 14 and the upper spacers 24 are attached to the sash frame 3b of the second panel body 3 on three circumferences except for the lower part. Excellent in nature. Furthermore, since the outer surface portion of the sash frame 2b of the connected first panel body 2 is also aligned in the inner and outer directions, the overall structure including the connected first panel body 2 and second panel body 3 has an excellent appearance. It can give a sense of unity. The upper spacer 24 may be attached to the lower frame of the sash frame 3b of the second panel body 3 as well.

The outer surface portion 6a of the first connecting frame 6 and the outer surface portion 14a of the spacer 14 are arranged so that the end portion opposite to the mullion 4 in the left-right direction is positioned more laterally than the left and right ends of the outer surface portion 20 of the mullion 4. Since it is located at a widened position, it does not overlap with the outer surface portion 20 when viewed from the outdoor side, and is visible. Therefore, even if the positions of the outer surfaces 6a and 7a of the first connecting frame 6 and the second connecting frame 7 are different in the inner and outer directions, the mullion 4 and each frame can be It is possible to make the inner and outer positions of the frames seem to be aligned in the visible part from the outdoor side while maintaining the versatility without changing the forms of 6 and 7.

In addition, since the spacer 14 and the second connecting frame 6 are flush with each other on the left side, which is the side opposite to the mullion 4, the spacer 14 and the second connecting frame 7 are integrated. It has a good appearance.

Further, the spacer 14 is composed of a first spacer member 15 and a second spacer member 16, and the first spacer member has an attachment end portion 15f to the second connection frame 7 for disposing the water stop material 17. It has a water stop material holding portion 15g. The second spacer member 16 has a pressing portion 16c that presses the water stop material holding portion 15g toward the outer surface portion 7a of the second connecting frame 7 from the outside of the room. As a result, the waterproof performance between the spacer 14 and the second connecting frame 7 is improved.

In addition, since the second spacer member 16 is provided with a protrusion 16d that abuts on the right side surface portion of the second connection frame 7 on the side of the connection member, the spacer 14 is attached to the second connection frame 7. The actual positioning is easy.

A method for constructing such a frame connection structure 1 includes a step of disposing the outer surface portion 6a of the first connection frame 6 on the outdoor side of the outer surface portion 7a of the second connection frame 7; a step of attaching the spacer 14 to the outer surface portion 7a of the body 7; It has a process.
