Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a seal method for sealing a gap formed at a cross portion of a unit joint in a unit type curtain wall by a dry seal method and a seal used for carrying out the method. Device.

[0002]

2. Description of the Related Art Conventionally, as a unit type curtain wall, for example, one shown in FIG. 5 is known. 8 in the same figure
Indicates a unit joint cross portion formed as a gathering point of four units 1. As shown in FIG. 6A, each unit 1 has an upper frame 2, a lower frame 3 and a vertical frame 4,
As shown in (b) and (c), joint packing 5 and dry seals 6 and 7 are attached to the four circumferences thereof so that the packing 5 adheres to each other to maintain the airtightness and watertightness of the unit joint. Composed. The unit 1 is constructed by sequentially assembling the joint packings 5 from the lower side to the upper side while assembling them together.

[0003]

Normally, external rainwater can be prevented by dry seals 6 and 7. The joint packing 5 completes the seal of the unit joint, but the cross portion of the unit joint is In FIG. 8, a diamond-shaped gap 9 was formed as shown in FIG. 6D, and this gap was a factor of lowering airtightness and watertightness.

That is, although the gap 9 is a slight gap, there is a problem that water may intrude from the gap 9 to cause water leakage to the inside and metal corrosion. In order to prevent this, conventionally, a method of manufacturing the corner portion of the joint packing 5 by a press joint has been attempted, but it has a drawback that it is expensive and is not practical.

An object of the present invention is to eliminate the above-mentioned problems of the prior art. Therefore, the gap generated at the cross portion of the unit joint is appropriately sealed at a low cost which can match the cost need. It is an object of the present invention to provide a seal method which can be stopped and a seal device used for carrying out the seal method.

[0006]

The feature of the sealing method for the cross joint portion of the unit joint packing of the curtain wall according to the present invention is that a seal is provided in the gap 9 of the cross portion 8 of the joint packing.
By providing a bag 11 containing a seal material, and then pulling out a string 12 attached to the bag, the seal material in the bag is caused to flow out to fill the gap in the cross portion with the seal material. is there.
The feature of the seal device according to the present invention is that the bag 11 containing the seal material 15 is installed in the gap of the cloth packing.
And the string 12 attached to the bag so that the seal material flows out of the bag and fills the gap.

[0007]

Therefore, in the method of the present invention, since the seal material 15 is filled in the gap 9 in the cross portion of the unit joint packing, the cross portion can be completely sealed by hardening the seal material. it can. The bag 11 containing the seal material is set on the cross portion 8 of the unit joint at the stage of mounting the unit for the carten-wall. The bag 12 is constructed so that when the string 12 is pulled, holes 13 or cuts are made and the seal material 15 inside flows out. Therefore, after the bag is installed at the cross portion, the seal material is pulled by pulling the string. Flows out and fills the gap 9 at the cross portion.

[0008]

Embodiments of the present invention will now be described with reference to the drawings. FIG. 1 shows a longitudinal section of a cross portion 8 of a unit joint which is sealed according to the present invention. The carten wall to which the present invention relates is also a unit type dry seal construction method. As shown in FIG. 1, joint packings 5 on the four circumferences of each unit 1 are in close contact with each other to maintain airtightness and watertightness. In addition to joint packing, dry seals 6 and 7 are attached to prevent rainwater from entering.

According to the sealing method of the joint packing cloth portion 8 according to the present invention, the gap 9 of the joint packing cloth portion is sealed.
For sealing, a bag 11 containing a sealing material is provided in the gap, and a string 12 attached to the bag is pulled to flow out the sealing material from the bag 11. The carten wall is constructed by assembling the unit 1 in a stacking manner from the lower side to the upper side while keeping the joint packings 5 in close contact with each other. It is installed on the cross portion 8 of the unit joint at the stage of mounting.

That is, the bag 11 is installed by, for example, mounting the lower unit 1 and then mounting the bag 11 on the cross portion of the end portion of the upper frame 2 of the unit, and as shown in FIG. This is done by placing the unit 1 above and then mounting the unit 1 above. The bag 11 is constructed so that the seal material inside the bag 11 flows out by pulling the cord 12. Therefore, as shown in FIG.
3 is formed or by pulling the string 12 the bag 11
It is designed to cut at a specific point.

Therefore, the seal material flows out from the bag 11 and is discharged so as to be squeezed between the joint packings 5 to fill the gap 9. The string 12 and the bag 11 may be pulled out as they are. Incidentally, even if all the strings 12 are not pulled out, a mark such as a red mark may be attached to an appropriate position of the string 12 in advance, and the string may be cut when the string 12 is pulled to that position. In that case, the bag 11 and a part of the string remain between the units, but are not visible from the outside and do not interfere.

FIG. 2 shows an example of a sealing device 10 comprising a bag 11 containing a sealing material used for carrying out the sealing method according to the present invention. The bag 11 is preferred. Is configured as a resin bag such as a vinyl bag.
The size of the bag is 20X20cm when flattened.
It is a degree.

In the seal device illustrated in FIG. 2, a seal retainer 14 is provided on the side of the bag opposite to the position where the string 12 is attached, and the seal retainer 14 is made of a plate piece and the bag 11 is attached. String 1 attached to the seal retainer 14 after it has been installed in place
By pulling 2a, as shown in FIG. 1, the seal material is pressed in and pressed against the joint packing 5.

The string 12a may be the same as the string 12 attached to the bag 11. In this way, when the seal retainer 14 is present, the bag 11 is joined to the seal retainer 14 by welding, and when the string 12 is pulled, the welded portion is cut so that the seal material inside flows out. It can also be configured.
Further, as shown in FIGS. 3 and 4, the seal retainer 14 may be omitted in some cases.

The seal material 15 to be inserted into the bag 11 is generally a one-component seal material such as silicon, polysulfide, and modified silicon, but is not limited to one-component material. In some cases, a two-component seal material is also used.

FIG. 4 shows another embodiment of the seal device, in which the bag 1 is pulled by pulling the cord 12 as described above.
Instead of producing holes 13 or cuts in No. 1, holes 13 are previously formed in the bag 11 as shown in FIG. 4, a sealing material is put in the bag 11, and the bag is covered with another bag 11a having no holes. You may ask. In this case, the outer bag 11a is removed immediately before it is installed in a predetermined position between the units, and in this state, the string material 12 is pulled out so that the seal material flows out from the hole 13 to fill the gap 9.

As described above, the seal device 10 is a seal.
It is composed of a bag 11 containing a lure material and a string 12 attached to the bag, and is installed on the cross portion 8 of the unit joint packing, and by pulling the string 12, the seal material is placed in the gap 9 of the cross portion. Is filled. The cross portion 8 between the units is completely sealed by hardening the seal material filled in the gap 9. Needless to say, such filling of the seal material is carried out for each cross portion 8 of the joint packing formed on the carten wall.

[0018]

As described above, according to the present invention, since the seal material can be filled in the gap formed in the cross portion of the unit joint packing, the gap can be completely sealed. . Moreover, since the sealing material can be easily and quickly filled and can be inexpensively manufactured, there is no problem in terms of cost and there is an advantage of excellent practicability.
