Attachments 40 having projecting pieces 41 are attached to the outer surfaces of the base pieces 22, 22' of the mullion constituent members 20, 21 at a plurality of locations in the longitudinal direction. The side edges of the installed fireproof panels are held in place.

FIG. 5 is a cross-sectional view taken along the - line in FIG.
0,71 are provided, and the upward concave groove 7 of the lower waist 3
0 and the downward groove 71 of the horizontal member 2, a window component (rotating window in the figure) 4 is installed, and the downward groove 71 of the waist member 3 and the upward groove 70 of the horizontal member 2 are installed. A face material constituting the spandrel 5 is attached between the two. A dining plate base 62 is attached to the indoor side of the waistband 3, and a dining plate 63 is attached to the indoor side of the dining plate base 62. An attachment 73 and a circumferential edge 74 of the attachment 72 on the indoor side are attached to the indoor side of the cross member 2, and the ceiling material 10 is fixed to the circumferential edge 74. The attachment 73 includes a vertical piece 75 and a mounting piece 76.
The fireproof panel 12 is mounted and supported on the mounting piece 76. The upper end of the fireproof panel 12 is a tray plate 63
It faces the space between the fireproof panel 12 and the attachment 77, and is designed to absorb displacement of the fireproof panel 12. Further, the fireproof panel 12 is a single plate having approximately the same length as the spandrel 5, and serves as a decorative board. A fireproof material 61 is provided between the fireproof panel 12, the waist joint 3, and the cross member 2.

The joint sleeves 31 and 32 connect the mullion component member 20 and the mullion member 20 at the joint position between the mullion 1 and the slab 6.
21, located on the inner surface of the bottom mullion 1 in Figure 2.
In this case, it is arranged at a position corresponding to the bottom slab 6 and at the top end of the bottom mullion 1, and in the middle mullion 1 it partially protrudes from the top end of the mullion as shown in Fig. 6, and in the top mullion it is located near the top end. It is installed inside the mullion.

Next, the assembly order of the divided mullions will be explained using an intermediate mullion as an example. In FIG. 7, the other joint sleeve 32 is fixed to the inner surface of the mullion component 21 to which the bracket 53 is fixed, with its upper part protruding from the mullion with bolts 54''. base piece 33'
A holding member 43 is provided at the bottom. A bracket 53 and a joint sleeve 31 whose tip protrudes from the mullion component 20 are also fixed to the mullion component 20, and a notch 49 is formed at the lower end of the outdoor side projecting piece 35 of the joint sleeve 31. There is.

When assembling, as shown in FIG. 8, first, the outdoor horizontal piece 24 of the mullion component 20 is engaged with the outdoor side bent piece 28 of the mullion component 21 already attached to the slab 6, and the outdoor side tight material 30 is attached to the corner. Then, the indoor flange 23 of the mullion component 20 is engaged with the indoor flange 23' of the mullion component 21, and the tight material 30 is pressed against the corner 29. After engaging the mullioned constituent members 20 and 21 on the indoor side and the outdoor side in this way, as shown in FIG. engage. At this time, the mullion component 20
The long groove 59 of the bracket 53 engages with the through bolt 55. After that, the screw 46 is inserted through the elongated hole 65 to connect both joint sleeves 31 and 32.

This invention has the above-mentioned structure, and in the connecting part of the left and right mullions in a divided mullion, one has a hollow part B, and the other has a pair of joints formed by bending a plate-like member without a hollow part. Into sleeve 31,3
2 is combined as a connecting member, so when an external force is applied in the wind pressure direction, that is, in the out-of-plane direction, the strength is maintained by the hollow part B, and when assembling the mullion, the plate-shaped joint sleeve 31 has elasticity. It is easy to construct because it can be deformed.

Further, since the double-standing structural members 20 and 21 are configured to prevent opening on the outdoor side by engaging the holding member 43 provided on the joint sleeve 32 with one joint sleeve 31, special screw fixing is not required. It is easy to assemble the necessary and double-sided structural members 20 and 21, and the engagement groove 45 of the holding member 43 is formed slightly wide, so that it can absorb the thermal expansion of the cross member and the cross member. It's getting old.

Projection 3 on the outer surface of joint sleeves 31 and 32
Reference numeral 8 effectively prevents metal contact with the mullion constituent members 20 and 21 to prevent abnormal noise from the mullion connecting portion, and also serves for positioning when attaching the back plate for bolt insertion and the holding member 43.

The connection between the bracket 53, the mullion component 21, and the joint sleeve 32 is made through the hollow portion B of the joint sleeve 32, so that it is strong.

The large diameter portion 46d of the screw 46 that connects both joint sleeves 31 and 32 has a function of keeping the distance between the backing plates 31 and 32 constant, and has a long hole in the mullusoidal component 20 through which the screw 46 is inserted. 65 absorbs the thermal expansion of the mullions.

(Effects of the invention) This invention consists of the above-mentioned structure, and a mullion is constructed by fitting each joint sleeve to the back surface of each mullion constituent member, and the mullion is positioned on the indoor side of this mullion. The constituent members and joint sleeves are fixed to the fasteners with bolts, the mullion constituent members and joint sleeves are fixed with screws at the center position of the mullion, and each Since the joint sleeves are engaged with each other by the holding members, the mullion component members, the joint sleeves, and the joint sleeves can be firmly connected at three locations: the indoor side, the center, and the outdoor side of the mullion. Although it is a divided mullion, a mullion with high rigidity can be obtained.

In particular, at the outdoor side of the mullion, the joint sleeves that are integrally fixed to each mullion component are integrally connected to each other via the holding member. The strength of the engaging part between the flanges is increased, and as a result, this part can firmly maintain the engaged state even against positive and negative pressure caused by strong winds, and can prevent wind and rain from entering from this part. be.

Furthermore, a holding member having an engagement groove that opens upward is fixed to one joint sleeve,
In addition, since the lower end of the other joint sleeve is configured to engage with the engagement groove, when the mullion component members equipped with the joint sleeves are engaged with each other and assembled, each mullion component After the indoor flanges of the members and the outdoor flanges of the members are engaged with each other and temporarily held, when one mullion member is moved downward, the lower end of the joint sleeve of this mullion member is moved to the other side. Since it engages with the engagement groove of the holding member which is fixed to the joint sleeve of the mullion component, assembly can be performed extremely easily and reliably.
