Description

[Detailed description of the invention] [Industrial application field] This invention relates to a mullion and seamless connection device, which connects the two at the same time by crimping the gap between the two that constitute the curtain wall. This makes it possible to improve airtightness and watertightness.

[Conventional technology]

BACKGROUND OF THE INVENTION With the recent development of building technology, buildings are frequently becoming taller. In this case, the curtain wall construction method is adopted in order to reduce the weight of the outer wall and save labor on site. As the rain closing method in this curtain wall construction method, a method using the equal pressure principle, which is more advantageous than the conventional sealing method, is widely used.

[The problem that the idea attempts to solve]

However, with the curtain wall having the above structure, construction is troublesome due to the complexity of the structure, and furthermore, even when installing mullions and blinds, there are complications such as having to take rain protection into full consideration. There is too.

[Means to solve the problem]

This idea was made in view of the above circumstances,
A fitting groove is formed on the side surface of the mullion, a side wall is provided protruding from the side surface of the fitting groove at a position closer to the interior of the mullion, and a sealing material is attached vertically to the outer surface of the side wall. A channel-shaped guide groove is provided on the inner surface, a recess formed in the continuous longitudinal end is fitted into the side wall, and a wedge is press-fitted between the guide groove and the recess, and this wedge is The present invention proposes a mullion and seamless connecting device characterized by providing a pair of upper and lower ends with the longitudinal ends of the mullion interposed therebetween.

[Effect]

In the device of this invention having the above structure, when connecting the mullion and the mullion, the wedge is placed closer to the room and is press-fitted from above and below along the guide groove.

〔Example〕

Examples of this invention will be described below based on the drawings.

Fig. 1 is a schematic front view of a curtain wall having a connecting device of this invention, in which a plurality of mullions 1, 1, etc. are installed vertically at appropriate intervals, and horizontally installed at appropriate intervals in the vertical direction. With multiple Mume 2, 2...
A plurality of frames 3, 3... are configured, and within each frame 3,
The structure is such that the mullions 1 and the mullions 2 support a facing material 4 such as a window panel or a spandrel panel. In this case, the mullion 1 is attached to the outside of the frame 5 by welding it to a bracket 8 which is fixed with a bolt 7 to a fastener 6 welded to the frame 5, as shown in FIG. This mullion 1 has a vertical groove 9 that opens to the outdoor surface.
and a hollow space 10 along the groove 9 on the indoor side of the groove 9. Fitting grooves 11, 11 are provided on both sides of the mullion 1, respectively, and the end portions of the blinds 2 fit into the fitting grooves 11, and the inner portions that are locked and fixed in the fitting grooves 11 are fitted. The face material 4 is supported by the ridge 13 and the outer ridge 12. In this case, a sealing material 14 is filled between the face material 4 and both ridges 12 and 13, and a vertical space 15 is formed between the fitting groove 11 and the face material 4, and this vertical space 15
is communicated with the outside air through an outside air inlet 16 formed on the outdoor side of the groove 9 in the mullion 1 and an air inlet 17 formed in the outer rim 12. The hollow space 10 is connected to the vertical space 1 through air inlets 18 and 19 formed in the mullion 1 and the outer rim 12.
It is connected to 5.

On the other hand, when fitting the end of the blind 2 into the fitting groove 11 of the mullion 1, as shown in FIGS. A side wall 20 is provided in a protruding manner, and a sealing material 22 is inserted into an engagement groove 21 formed on the outer surface of the side wall 20 in the vertical direction.
This sealing material 22 is attached to the mullion 1, a blind bracket 23 is provided protrudingly at a predetermined position on the side of the mullion 1, and a cut is made at the end of the blind 2. After fitting the missing recess 24 into the side wall 20 of the fitting groove 11 having the sealing material 22 and placing it on the blind bracket 23, a channel-shaped guide groove 20' provided on the inner surface of the side wall 20 is inserted. The wedges 25, 25 are press-fitted from above and below into the gap between the recess 24 formed at the longitudinal end of the mesh 2, the sealing material 22 and the mesh 2 are pressed together, and the wedge 25 is inserted into the mullion 1. Fixed to. In this case, the wedge 25 is made of synthetic resin such as nylon, and as shown in FIG. The wedge main body 25c has a protruding piece 25b that protrudes at right angles, and has a wedge surface 25d on an inner surface that protrudes in the opposite direction to the mounting piece 25a from one end of the protruding piece 25b that is perpendicular to the protruding direction. has been done. Therefore, by press-fitting the wedges 25, 25 configured in this way into the gap between the mullion 1 and the blind 2 from above and below with respect to the blind 2, the gap 2 and the sealing material 22 can be uniformly applied. It can be crimped.

On the other hand, as shown in FIG. 6, the blind 2 has a stepped portion 26 on the outdoor side for attaching the face material, and cooperates with a batten 27 that is locked and fixed on the outdoor side of this stepped portion 26. The lower end portions of the panel 4 are fitted and fixed into the panel mounting portions 28, 28, respectively, with a sealing material 29 interposed therebetween. Horizontal spaces 30 and 31 are formed between the lower end of the face material and the face material attachment parts 28 and 28. Reference numeral 31 denotes a horizontal space formed by the upper end of the face material 4 and the blind part 2. A piece-shaped setting block 32 is interposed between the lower end of the panel 4 and the panel mounting portion 28 to ensure a horizontal space 30. The horizontal space 30 is communicated with the outside air through outside air inlet ports 33, 33, which also serve as exhaust ports, which are bored on the side of the batten 22, and the horizontal spaces 30, 31, 32 are connected to each other at the ends in the longitudinal direction. It communicates with the vertical space 15 at this portion. Therefore, inside the horizontal spaces 30 and 31,
The pressure becomes equal to the outside air pressure through the outside air inlets 33, 33... or the vertical space 15 communicating with the outside air.

In addition, in the portion of the vertical space 15 of the mullion 1 that communicates with the horizontal spaces 30 and 31, there is a catch pan 3.
4 is arranged (see Fig. 7), and this catch pan 34 discharges rainwater falling from above to the side of the horizontal space 30, and discharges it outside from the outside air inlet 33 which also serves as a drainage outlet. It's summery.

[Effect of idea]

As explained above, the coupling device of this invention provides the following effects. In other words, since the wedge can be press-fitted indoors, the work can be done safely without any danger.

Since the wedge is press-fitted from above and below along the guide groove, reliable pulling is possible.
