Description

[Detailed explanation of the invention] This invention consists of vertical mullions that are parallel to each other, and a surface material such as glass that is placed in a frame that is formed as a plurality of horizontal mullions connected in parallel between adjacent mullions. This invention relates to a rain protection mechanism in a curtain wall that is fitted with a curtain wall.

Conventionally, as shown in Fig. 7, this type of mullion was formed by forming a blind groove d on the side surface of a substrate a with an inner flange b and an outer flange C having a cross-sectional shape, and attaching it to the inner flange b. It is known that a groove g into which a face material f is fitted is formed by a raised edge e and an outer flange C.

However, since the thickness of the blank in the inner and outer directions is generally larger than that of the face material, in the conventional mullion described above, when the blank end is fitted into the blank insert groove d, A part of the outer flange C corresponding to the mating position must be removed, and if an equal pressure structure is to be adopted, an outside air inlet must be provided in the outer flange, but it is long and heavy. It is not easy to accurately perform the above-mentioned processing on mullions, which not only results in insufficient watertightness of the resulting curtain wall, but also causes a decrease in work efficiency.

The purpose of the present invention is to eliminate the drawbacks of the conventional technology, and its feature is that, in a mullioned body having a continuous groove on the side surface, there is a space in the part where the face material of the continuous groove is to be fitted. An outer rim is attached to the outside to form a face material fitting groove, and an outside air inlet is provided on the outer rim to allow the face material fitting groove to communicate with the outside air.

The present invention will be described in detail below with reference to the drawings showing a mullion in a curtain wall.

In Figure 1, mullions 1... are stood parallel and perpendicular to each other at appropriate intervals, and mullions 2... are placed at appropriate intervals between adjacent mullions 1 and 1. The vertically long rectangular frame formed by these mullions and mullions are connected in parallel with each other, and the frame of the spandrel part facing the floor 3 is covered with a metal plate, glass plate, etc. At the same time, a transparent surface material 4' such as a glass plate is fitted into the frame of the opening portion that does not face the floor 3.

As shown in the second figure, the mullion main body 1' has outer flanges 6.
6 and the inner flange 7.7 are respectively extended to form U-shaped blind grooves extending over the entire length in the longitudinal direction of the base plate 5 and the flange 6.7 on both left and right side surfaces, respectively.
A bracket 9 is welded to the inner flange 7.7 with legs 8.8 protruding inwardly at positions corresponding to the spandrel portions of the legs 8, 8, and the bracket 9 is fixed to the floor 3. Bolt 11 to anchor 10. It is fixed with a nut 12.

As shown in the third figure, the cross section of the blank 2 has a hollow rectangular shape, and the face material 4 is inserted into the face material fitting grooves provided on the upper and lower walls 13 and 14 through tight materials 15 and 16, 17, respectively. Or, the upper or lower lateral sides of 4' are fitted respectively, and an inclined transverse bulkhead 18 that is slightly downwardly inclined outward is provided at the middle part of the interior of the interior, and a horizontal partition wall extending over the entire length of the interior is provided between the upper wall 13 and the upper wall 13. A space C is formed, and a vertical partition wall 21 extends vertically from the outside of the lower surface of the horizontal partition wall 18 with a small distance from the front wall 20. Alternatively, a small space which is fully opened outside of 4' is formed, and a plurality of first drain ports 23 communicating with the small space are provided in the horizontal partition wall 18 at appropriate intervals.

In addition, an auxiliary horizontal wall that divides the small space extends from the middle part of the vertical partition wall 21, and the discharge port 23 is also provided in the auxiliary horizontal wall.
A second drain port 24 corresponding to... is provided.

Insert both ends of such a blind 2... into the blind swallowing grooves of the adjacent mullion bodies 1', 1', and swallow each blind end through the appropriate bracket. fixed in the groove, and
The open end is filled with caulking material, and a catch pan 25 is attached to the upper surface of the open end.

On the inside of the outer flange 6 of each mullion main body 1', outer ribs 26 are attached, the upper and lower ends of which contact the vertically adjacent blinds 2, 2, and on the inside of the inner flange 7, the vertically adjacent blinds 2, 2 are attached. An inner ribbed edge 27 whose upper and lower ends are in contact with each other is attached to each of the outer ribbed edges 26 and one end of the inner ribbed edge 27, and a face material fitting groove is formed with a narrower groove than the above-mentioned open slot groove, and a tight material is inserted into the groove. The left or right vertical side of the panel 4 or 4' is held between the panels 15 and 16, respectively.

If the above-mentioned face material is thick, the vertical sides of the face material may be held in the face material fitting grooves formed between the inner flange 7 and the outer ridge 26 without attaching the inner ridge 27.

As shown in the second figure, the outer rim 26 has auxiliary walls 29 and 30 on the inner and outer surfaces of the outer rim main body wall 28 in the cross section.
, 31, 32, 33, wall 30 outside 7 langes 6
The wall 33 is attached to the locking step 35 of the cubic board 5.
A first vertical space A extending over the entire length of the outer ridge is formed between the outer ridge 26 and the mullion 1, and a first vertical space A extending over the entire length of the outer ridge is created between the outer ridge 26 and the mullion 1, the inner ridge 27 and the face member 4 or 4'. A second vertical space B extending over the entire length of the outer rim is formed between them, and a plurality of first outside air inlets 36 are formed in the wall 30 to communicate the first space A with the outside air, and a first space B is formed in the main body wall 28. A plurality of second outside air introduction ports 37 are provided to communicate the space A and the second space B, respectively.

In FIG. 2, 38 is a screw that fixes the inner ribbed edge 27 to the mullion 1, and 39 is a sealing material that seals the inner ribbed edge and the mullion 1.

The legs 8, 8 at the opening of the mullion 1 are covered with a cover 40, as shown in the fourth figure.

To explain the rain control effect based on the equal pressure structure, the inside of the spaces A, B, C, and D instantly becomes equal to the outside pressure through the outside air inlets 36, 37 and the drains 23, 24.

In this case, the drain ports 23 and 24 may be appropriately enlarged to actively introduce outside air.

When introducing outside air as described above, for the mullion side, the outside air first enters the first vertical space A through the first outside air inlet 36, then enters the second vertical space B through the second outside air inlet 37, and Space A
, B instantaneously become equal to the outside pressure, thereby sufficiently preventing the intrusion of rainwater based on the principle of equal pressure.

Also, raindrops with kinetic energy enter the space A from the inlet 36.
However, such raindrops are prevented from entering the space B by the auxiliary wall 32 and the outer rim main body 28, and then flow down the auxiliary wall 32 and the outer rim main body 28 onto the catch pan 25. Then, from the outlet of the catch pan 25, it flows down into the horizontal space C from the open face material fitting groove of the blind 2, and then the drain 23, the space D, and the drain 2.
4 and is discharged to the outside.

Atomized water droplets that are not treated in the first vertical space A and enter the second vertical space B from the inlet 37 hit the auxiliary walls 31, 33 of the outer rim and the inner rim 27 and hit the catch pan 2.
5, and is led to the horizontal space C of the mumu 2 and is discharged through the drain port 23, the space D, and the drain port 24.

Therefore, there is no danger of rainwater hitting the tight material 16.39.

In the present invention, the above-mentioned 1. Second vertical space A
, B formed in one vertical space can also be implemented.

Further, the upper inner ribbed edge 27 may be integral with the mullion 1.

Further, on both sides of the lower part of each shaft, plate guide blocks 41 and 41 are respectively provided, and the guide blocks 41 are made of synthetic resin, and have inclined surfaces 42 on the side surfaces as shown in figures 5 and 5a, and have fitting grooves 43. It is installed by fitting the fitting groove 43 into the auxiliary wall 31 with the inclined surface 42 facing the face material fitting groove.

Both guide blocks 41, 41 automatically position the panel in the correct position using the inclined surface 42, 42 when the panel is dropped into the frame from above, and after installing the panel, the panel can be moved during an earthquake. I will carry out Letter 11 to prevent this.

The tight member 15 is made of an elastic material such as rubber or synthetic resin, and has three legs 15a extending from the main body which is curved in an arch shape in the cross section as shown in Figure 6. The outer curved surface of this tight material 15 is connected to the outer ribbed edge 26.
The arc-shaped concave recess having the jagged edges fits into the surface 15b and prevents it from falling off.

According to this invented curtain wall rain protection mechanism,
When making a seamless connection and fitting a face material, the blind end should be fitted into the mullion's blank insert groove and connected, and at the same time it should be removably locked to the locking step on the mullion body. All you have to do is fit the facing material into the facing material fitting groove formed by the outer ribbed edge, and there is no need to perform cutting on long and heavy mullions as in the past, thereby creating a curtain wall with sufficient moisture resistance. In addition to this, it is possible to improve work efficiency.

Furthermore, in this invention, the outer rim is short, lightweight, and can be easily manufactured into complex shapes, so in order to adopt an equal pressure structure in the mullion, outside air can be introduced by providing an outside air inlet, etc. on the outer rim. Not only does machining work such as openings become easier, but it also makes it easier to construct an effective isobaric structure, and the auxiliary wall provided on the outer rim completely prevents raindrops from entering the face material fitting groove. Its value is extremely high.
