Description

[Detailed Description of the Invention] [Industrial Application Field] The present invention relates to a device for sealing between upper and lower mullions in a curtain wall.

[Conventional technology]

A gap is provided between the upper and lower mullions to absorb expansion and contraction of the mullions.

For this reason, if the ribs for attaching panel members to the mullions are installed continuously between the upper and lower mullions, the metal ribs and the metal mullions will expand and contract relative to each other in the longitudinal direction. Since this would result in squeaks between the metals, the rim is made to have the same length as the mullion and is divided into upper and lower rims to prevent the squeaks between the metals.

However, in this case, when installing the sealing material between the upper and lower mullions, the sealing material cannot be received, making it troublesome to install the sealing material.

Therefore, conventionally, as shown in FIG.
As shown in FIGS. 2 and 3, the back-up material receiver 3 is engaged with the ridge 2 of the upper mullion 1, and the back-up material 5 is pushed into contact with the back-up material receiver 3. A sealing material 6 is attached to the outside of the backup material 5.

In this way, the sealing material 6 can be supported by the backup material 5 and the backup material receiver 3, so that the sealing material 6 can be easily installed.

However, in the above-mentioned structure, the back-up material receiver 3 is fixed to the rim 2 with the screw 4, which increases the number of parts, making inventory management, transportation, etc. troublesome. Since the back-up material receiver 3 is installed by drilling a screw hole and screwing the screw into the screw hole, the work of installing the back-up material receiver 3 becomes troublesome and the work of connecting the mullions becomes troublesome.

[Purpose of invention]

To easily install a sealing material between upper and lower mullions without attaching any special members, and to prevent the generation of squeaks between metals.

[Structure of the idea]

The ribbed edge is made longer than the mullion so that the ribbed end protrudes from the mullion end face, and the sealing material is received at the protruding portion.

〔Example〕

FIG. 4 is a side view of the mullion connection part, FIG. 5 is a cross-sectional view, and FIG. 6 is a perspective view of the mullion part.
The hollow base 11 and the horizontal wall 12 are connected by a connecting wall 13 to form a recess 10b for attaching the panel material in the longitudinal direction, and the locking piece 1 of the hollow base 11 is
1a and the locking piece 13a of the connecting wall 13, that is, the left and right ribs 14, 1 are on one side of the panel material mounting recess 10b.
4 is engaged, and a glass 15 serving as a panel material is mounted between this ridge 14 and the side wall 12, that is, the other side of the panel material mounting recess 10b.

The longitudinal length of the ridge 14 is slightly longer than that of the mullion 10, and both longitudinal ends 14 of the ridge 14 are
a slightly protrudes from both end faces 10a in the longitudinal direction of the mullion 10, and the surface facing the other side of the panel material mounting recess 10b of the mullion 10 at the ends 14a, 14a of the upper and lower ribbed edges 14, 14 A backup material 16 is attached to the end portions 14a, 14a in contact with each other between the surfaces of the end portions 14a, 14a, and a sealing material 1 is attached to the backup material 16.
7 is installed.

18 is a caulking receiver.

Because of this, the backup material 16 and the sealing material 17 can be supported by the end portion 14a of the ridge 14 so that they do not fall off, and the backup material 16 and the sealing material 17 can be easily attached.

In addition, since the rim 14 is only slightly longer than the mullion 10, and there is no need to attach any special parts, the number of parts is reduced, inventory management, transportation, etc. are easier, and special processing is not required. Since there is no need for special installation work, the cubic connection work becomes easy.

[Effect of idea]

End face 10 of mullion 10 of vertically adjacent ridges 14
Backup material 16 is attached to the end 14a protruding from a.
and apply sealing material 1 between the upper and lower mullions 10 and 10.
7 can be easily attached, and since the ribs 14 are attached to each of the upper and lower mullions 10, there will be no squeak noise between the metals.

In addition, since the longitudinal length of the rim 14 is only slightly longer than that of the mullion 10, and there is no need to attach any special members, the number of parts can be reduced, inventory management, transportation, etc. can be simplified. Since there is no need for any special processing or special installation work, connecting the cubes becomes easy.
