JPS595737B2 - Connection structure of mullions in curtain wall - Google Patents

Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to an improvement in the connection structure of mullions in a curtain wall.

As shown in Figures 5 and 6, the conventional connection structure for mullions is to attach a metal fitting with a protrusion C and a metal fitting F with a concave part E to the upper and lower mullions A and B, respectively, and connect the upper and lower mulluses. It has been proposed that a sealing material G is applied between A and B so that when they are joined together, the convex part C of the metal fitting fits into the recess E of the metal fitting F and they are connected.

However, the upper and lower mullions A. If the seal becomes incomplete due to a defect in the seal between B, expansion and contraction of the upper and lower mullions, changes in hot water temperature, or damage due to aging, rainwater will leak from the incomplete seal to the indoor side of the mullion. It has the disadvantage that it enters the room as droplets and contaminates indoor ceilings, etc. through the route shown by the arrow in Figure 6.

Furthermore, in the conventional method, special consideration had to be given to drainage of condensed water generated on the indoor side of the mullion.

Here, the present invention eliminates the risk of rainwater intruding into the interior of the room even if the seal that separates the joint between the upper and lower mullions is damaged, and moreover, the connecting device itself also serves as a means for draining intruding water or condensation water. This design was made with the intention of making the structure extremely simple and reducing the cost, and the details will be explained below with reference to the embodiments shown in the accompanying drawings.

'In Figures 1 to 4, 1 is a lower vertical member, and an upward connecting member 2 is attached to the upper end of the lower vertical member 1.
is fixed by welding.

In FIG. 1, numeral 3 indicates a welded portion, and 4 and 5 indicate seal portions, respectively.

The upward connector 2 mainly consists of a saucer-shaped base 6 and a rising edge 7 that is connected to the base 6 and extends upward to cover the portion facing the indoor side of the connecting portion of the upper and lower vertical members.

On the other hand, a downward connecting tool 10 is fixed by welding to the lower end of the upper side upright 9 which is connected to the lower side upright 1 via the sealing part 8, and in this case, 11 is the welding part and 12 is the sealing part. Reference numeral 8 indicates a back-up material for the sealing material, and 13 indicates a sealing portion (see FIG. 4).

The lower surface of this downward connector 10 is provided with a hanging edge 14.15 projecting to slidably engage with the rising edge 7, and the upper surface thereof is provided with a condensation water receiving portion 16 for receiving condensation water generated inside the interior of the upper standing timber room. will be established.

A drainage channel 17 provided in this condensation water receiving portion 16 and the hanging edge 1
The condensation water receiving portion 16 communicates with the base 6 of the upward connector 2 through a drainage channel 18 provided at the base 6, and a drainage channel 19 provided at the base 6 connects to the glass fitting space 20 of the mullion (Fig. 1). ) to the outside.

More specifically, the water flows down to the upper wall 21 (FIG. 3) on the lower side connected to the space 20, and is drained outdoors through the drain port 22.

The hanging edge 15, together with the rising edge 7, has the function of preventing rainwater from splashing into the interior of the room when the seal part is damaged and rainwater is blown into the room.
5 may be omitted and the inner surface of the rising edge 7 may be brought into direct sliding contact with the indoor surface of the upper upright member 9 to cover the indoor side of the seal portion 8.

In the above embodiment, the downward connector 10 has a hanging edge 14.1.
5, and the rising edge 7 of the upward connector 2 is slidably engaged therebetween, but the rising edge 7 is formed into two strips and the hanging edge is engaged between these rising edges. It is also possible to reverse the unevenness relationship.

In addition, the hanging edge 14 mainly has the upper side standing member 9 and the lower side standing member 1.
Since the purpose is to prevent movement toward the outside, it is sufficient to provide it only partially as shown in FIG.

The condensed water collected in the condensation water receiver 25 of the serving plate 24 of the upper lower bowl 23 flows down to the condensation water receiver 16 via the hose 26.

As described above, this invention provides an upward connecting tool 2 for the lower mullion 1.
and the downward connecting tool 10 of the upper side standing members 9 are connected to the upper and lower standing members 1, 9
It is excellent in that it simplifies the structure of the connecting part of the upper and lower vertical members and is reliable in use because it serves as a means to prevent rainwater from entering and a means to drain condensed water in the event that the seal part of the joint part is damaged. It is an invention.
