Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to mullions, and more particularly to mullions that are used for curtain walls and the like and are arranged continuously in the longitudinal direction.

Generally, mullions used for curtain walls, etc.
Since it is a 6m long member, its length changes as it expands and contracts due to temperature differences.

For this reason, the caulking material filled between the end faces of the mullions arranged continuously in the longitudinal direction often peels off after many years of use, resulting in poor water retention.

This invention was devised in view of the above circumstances, and
By increasing the adhesive area of mullion conking material without increasing the wall thickness of the entire mullion, it can fully adapt to changes in the longitudinal direction due to expansion and contraction of the mullion and maintain watertightness for many years. The purpose is to provide a mullion that can

(See figure) A back-up material 12 is provided, and a space is formed by the front surface of the back-up material 12, the end surfaces of the caulking members 6, 6, and the end surfaces of the exterior material support portions 2b of the mullions 2, 2. The space between each mullion 2 is sealed by filling the space completely with caulking material 4.

The receiver body 11 is fixed at one end by screwing the tip of a screw 14 fitted into the front plate 9a of the mounting frame 9 attached to the lower mullion 2, for example, and fixed at the other end. For example, it is attached so as to be in close contact with the back side of the front plate 9a of the mounting frame 9 attached to the upper mullion 2.

As mentioned above, the caulking receiver members 6, 6, etc. are installed on the back side of both ends of the exterior material support part 2b of the mullion body, flush with the longitudinal end surface of the exterior material support part 2b. By being fixed, the area of the longitudinal end face of the mullion 2 can be increased without increasing the wall thickness of the entire mullion, and therefore the adhesion area between the mullion and the caulking material 4 can be increased, and it has been used for many years. It is possible to maintain watertightness.

In the above embodiment, the case of a mullion on the plane part of the curtain wall 1 has been described, but the same applies to the case of a mullion in the corner shown in FIGS. 7 and 8, and as shown in FIG. The corner mullion 2 has a rectangular tube portion 2a that serves as an attachment portion to the building body and a connection portion in the longitudinal direction, and a pair of rectangular tube portions 2a that protrude perpendicularly from one corner of the rectangle tube portion 2a. A mullion body consisting of exterior material support parts 2b, 2b, and a back side of both ends of the exterior material support parts 2b, 2b of the mullion body, flush with the longitudinal end surfaces of the exterior material support parts 2b, 2b. The fixed abbreviated caulking receiver is member 6゜6...

A caulking receiver partially fixes a member 6 to the back side of at least one end of the mullion body, which is made up of an exterior material support part 2b protruding from the side surface of the mullion body, flush with the longitudinal end surface of the mullion body. However, the wall thickness of the longitudinal end face of the mullion is the sum of the wall thickness of the mullion main body and the wall thickness of the caulking member 6. Therefore, when arranging the mullions continuously in the longitudinal direction, It is possible to increase the adhesion area with the caulking material filled between each mullion, and as a result, it can fully adapt to changes in the longitudinal direction due to expansion and contraction of the mullions and maintain watertightness for many years. Furthermore, since the caulking member 6 is only partially fixed to the back side of the end of the mullion body, it is extremely economical compared to a method that increases the wall thickness of the entire mullion. Not only that, but it is also extremely easy to manufacture.
