Abstract

PURPOSE: To prevent the generation a variance of a joint by including an abutting member fitted in each space of jambs which join each of adjacent units on the same level and transmitting the movement of the units by way of abutting and thereby displacing their positions. CONSTITUTION: Abutting members 18 are installed to jambs 8 which join adjacent units each other. When an interlaminar displacement is produced, the abutting members 18 abut each other so that the adjacent units may move together. Then, the amount of displacement of each unit 1 is equalized and a compression force which exerts on joint gaskets 13 to 16 and the amount of deformation are unified. In this case, if a drainage groove is installed on the top of the abutting members 18, it will be possible to drain the water which falls down in the space of the jambs 8 by receiving the drainage water thereon. A sport material 25 which is inserted in across the jambs 8 of the upper and lower adjacent units 1, is included, thereby preventing the joints from being varied with the abutting members 18 and regulating the interlaminar displacement to a definite amount. Furthermore, the spot materials 25 are arranged to be laid out with ease so that interlaminar displacement to each side may be properly regulated.

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a unit curtain wall assembled by a fitting method, and more particularly to a joint variation preventing structure for preventing variations in joints between units.

[0002]

2. Description of the Related Art This type of unit curtain wall is manufactured as a unit in a factory including all materials such as glass, fireproof board, mounting bracket, etc. Therefore, it is brought into the site as a unit. Assembled and assembled. In this unit cart wall, the unit composed of the size from floor to floor is the standard, and the upper and lower sides and left and right sides of each unit are fitted by the continuous fitting method (interlocking method), and the dry method is used. Composed of. Therefore, there are advantages that the rate of factory production is high, the quality is high, the construction period is shortened, there is no need to build a scaffold at the time of construction, and construction can be performed even in the rain.

FIG. 7 shows an example of a unit curtain wall. As shown in the drawing, the unit 1 as a constituent element is arranged side by side vertically and horizontally and is constructed by a fitting method.
Then, as shown in FIG. 8, a bracket 2 is attached to each unit 1, and each unit 1 is mounted on a front fastener-4 (FIG. 10) installed on a slab 3 constituting a floor of a building by the bracket. It is fixed by suspension and the adjacent units are connected to each other by a joint material 5.

FIG. 9 and FIG. 10 show a horizontal cross section and a vertical cross section of a conventional unit curtain wall, in which 6 is an upper frame of a lower unit and 7 is a lower frame of an upper unit. 8 is a vertical frame. As illustrated, the bracket 2 is fixed to the vertical frame 8 and is fixed to the fastener-4 fixed to the slab 3 with the bolt 9 by the bolt 10.

Similarly, the space between them is sealed by packings 13 and 14, and atmospheric pressure is introduced into the space between the packings to form a constant pressure space.

[0005]

As described above, since each unit 1 of the unit curtain wall is mounted on the slab 3 by hanging, the slab 3 is interposed between the units when an interlayer displacement is caused by an earthquake or the like. The amount of slide is the same as the amount of displacement, and the amount of slide is considerably large in some cases. For example, if the spacing between slabs 3 is 4000 mm, then 1/100
When the interlayer displacement occurs, the displacement amount becomes 40 mm.

When the units undergo the interlayer displacement as described above, the joint size between the adjacent units on the left and right sides and between the upper and lower units varies, and the amount of deformation of the packing between the units and the load applied to the packing also vary. However, there is a problem that it becomes difficult to maintain the sealing performance, the sealing is broken in some cases, and there is a risk of water leakage.

An object of the present invention is to eliminate the above-mentioned problems of the prior art. Therefore, when the interlayer displacement occurs, the load and deformation amount on the packing between the upper and lower units and the left and right units are made uniform. It is an object of the present invention to provide a joint-curtain wall joint variation preventing structure capable of maintaining seal performance and avoiding problems such as seal breakage.

[0008]

In order to achieve the above-mentioned object of the present invention, the joint variation preventing structure of the unit curtain according to the present invention is a unit type curtain wall assembled by a fitting method. In this case, each unit has a floor-to-floor size, and a bracket attached to each unit connects the adjacent units to each other in a unit curtain wall which is suspended and fixed to a slab on the floor. Abutting members fitted at approximately the same level in the respective spaces of the vertical frames, wherein the abutting members of the vertical frames joined to each other are generally in contact with each other so that movement of a unit can be transmitted to an adjacent unit. It is characterized by

In a preferred embodiment of the present invention, the abutment member is installed at the lower end of the vertical frame and receives the water outside in the center of the upper surface of the vertical frame in order to receive the water descending in the space inside the vertical frame and discharge it to the outside. It is characterized in that a groove descending toward the groove is provided, and both sides of the groove are inclined surfaces descending toward the groove.

It is characterized by including.

In still another preferred embodiment of the present invention, the lower part of the hitting member is inserted into the vertical frames of a pair of lower adjacent units without gaps on both sides, and the upper part of the hitting member is paired with the upper pair. It is characterized in that it is inserted into the vertical frame of the adjacent unit with appropriate gaps on both sides.

[0012]

In this unit cart wall, the abutting members are installed on the vertical frames of the adjacent units which are joined to each other, and the abutting members are substantially in contact with each other. The mating members abut each other, the adjacent units move together, and the displacement amounts of the units become equal. Therefore, the compressive force and the amount of deformation applied to the joint packing of each unit become uniform, and a situation in which some units are largely displaced can be avoided, and the seal performance is maintained appropriately.

If the abutment member is installed at the lower end of the vertical frame and a drainage groove is provided on the upper surface thereof, the abutment member receives the water descending the space in the vertical frame and drains it to the outside. It is possible to prevent the dispersion of joints and to use it for drainage.

Further, by including a vertical member of the adjacent unit and a hitting member inserted over the vertical frame of the adjacent unit above or below the unit, the abutment member prevents the joint variation.
It is possible to make the displacement uniform and regulate the interlayer displacement to a constant amount.

In addition to the above-mentioned hitting member, the lower part of the corresponding hitting member is inserted into the vertical frame of the lower adjacent unit without any gap, and the upper part of the hitting member is suitable on both sides of the vertical frame of the upper adjacent unit. With such a structure, the contact member can be easily installed, and the interlayer displacement on each side can be appropriately regulated.

[0016]

DESCRIPTION OF THE PREFERRED EMBODIMENTS The present invention will now be described with reference to the drawings. 1, 2 and 3 show an embodiment of a unit curtain wall provided with a joint variation preventing structure according to the present invention, and this unit curtain wall also has a structure as shown in FIG. An appropriate number of units 1 are arranged side by side vertically and horizontally, and each unit 1 includes a bracket 2 and a front fastener.
It is fixed to the slab 3 by way of 4 by hanging.

Further, as shown in FIGS. 1 and 2, a pair of packings 1 is provided to seal between the upper frame 6 and the lower frame 7.
1 and 12 are provided and a pair of packings 13 and 14 are provided to seal between the vertical frames 8. In a more preferable form, a pair of packings 15 and 1 having an annular cross section that abut against each other between the packings 13 and 14 between the vertical frames 8.
6 is installed, and a packing 17 having an annular cross section is also provided on the indoor side of the packing 12 between the upper frame 6 and the lower frame 7 to complete the sealing.

As shown in FIGS. 2 and 3, the structure for preventing the dispersion of the joints between the units according to the present invention is fitted into the spaces of the vertical frames 8 of the adjacent units 1 which are joined to each other at substantially the same level. Abutting member 1 of vertical frames 8 joined together, characterized by including abutting members 18 fixed together.
8 are substantially in contact with each other. The term “generally contact” as used herein means a state in which they are in contact with each other or almost in contact with each other and are in close proximity to each other. The abutting member 18 can be installed at an appropriate height position of the vertical frame 8. However, since each unit 1 is suspended and fixed, the abutting member 18 is preferably installed below the vertical frame 8.

As shown in FIG. 2, the abutting member 18 is installed by fitting it to a hollow portion 19 existing on the outside of the packing 13 of the vertical frame 8 and fixing it with a screw or the like. It has a shape corresponding to the cross-sectional shape of 19. Although a groove is formed on the upper surface of the abutting member 18 in the illustrated example, the upper surface may be simply a flat surface, and thus may have a block shape. This abutting member 18
Although it may be made of any material, it is preferably made as a resin molded product, and if it is made of resin, it has the advantages of being easy to manufacture and not producing a squeaking noise when they come into contact with each other.

Preferably, as shown in FIG. 4, the abutment member 1
A protrusion 20 is formed on the side surface of the inner side of the chamber 8 which is inserted into the vertical joint 21 between the vertical frames 8 as shown in FIG. There is an advantage of adjusting the joint width.

Preferably, the abutting member 18 is also used as a drainage member, in which case the abutting member 18 is installed at the lower end of the hollow portion 19 of the vertical frame 8 as shown in FIG. As shown in FIGS. 2 and 4, a groove 22 that descends toward the outside is formed at the center of the upper surface, and both sides of the groove are inclined surfaces that descend toward the groove.

By providing such a groove 22 on the upper surface of the abutting member 18, as shown in FIG.
And 12, and rainwater that has entered each of the isobaric spaces between the packings 13 and 14 is received by the catch pan 23 of the upper frame 6 and passes through the water draining hole 26 located in the vicinity thereof, and the hollow portion of the vertical frame 8 is provided. 1
The water that has flown down to 9, and has flown down to the hollow portion 19 is received by the abutting member 18, and is discharged to the outside through the joint closing member 24 placed on the top of the upper frame 6 directly below it.

Further, preferably, as shown in FIGS. 1, 2, 5, and 6, in order to regulate the interlayer displacement between the upper and lower units 1, the vertical frames 8 of a pair of adjacent units 1 and the adjacent vertical frames 8 thereon. A contact member 25 is installed across the vertical frames 8 of the pair of units 1. Due to the interposition of the contact member 25, the contact member 25 slides by the gap between the contact member 25 and the internal space of the vertical frame 8 into which the contact member 25 is inserted, and further displacement is caused by the deformation of the vertical frame 8. It is absorbed and therefore the interlayer displacement is suppressed to a constant amount.

As shown in FIG. 5, the contact member 25 is composed of an elongated beam-shaped base portion 25a and insertion portions 25b and 25c provided above and below, respectively, and these insertion portions are respectively provided with upper and lower vertical frames. It is inserted in the space between 8. 25d is hit material 2
As shown in FIG. 2, the mounting portion 5 is inserted into a concave portion provided in the flange portion of the vertical frame 8 and serves to fix the contact member 25.

As shown in FIG. 6, the hitting member 25 is preferably a lower part of the hitting member 25, that is, the lower insertion portion 25c is inserted into the vertical frame 8 on both sides without a gap and the hitting member 2
The upper part of 5, 5, that is, the upper insertion part 25b is inserted into the upper vertical frame 8 so that appropriate gaps (d) are formed on both sides. The gaps (d) on both sides are equal as shown in the figure, and this dimension (d) is the slidable amount. The thickness (m) of the base portion 25a is preferably equal to the joint size in the vertical direction, which facilitates the vertical positioning of the unit 1 and reduces the crushing amount of the annular packing 17 between the upper and lower units. Keep it constant.

In the unit curtain wall having the joint variation preventing structure, the abutting members 18 are installed at the same height positions of the vertical frames 8 of the adjacent units 1 which are joined to each other, and the abutting members 18 are provided. Are configured to generally contact each other, so that when an interlayer displacement occurs in this unit curtain wall, the abutting members 18 adjacent to each other abut each other, and therefore the adjacent units move together, and thus each unit moves. The displacement amount of the unit becomes equal, the joint becomes uniform, and there is no variation.

Since the vertical joints and the joints between the upper and lower portions do not vary even when the interlayer displacement is applied in this way, it is possible to avoid a situation in which some of the units 1 are largely displaced as compared with others.
Therefore, the compressive force and the amount of deformation applied to the joint packing between the units 1 become uniform, and the seal performance is preferably maintained.

By installing the abutting member 18 at the lower end of the vertical frame 8 and providing a drainage groove on the upper surface thereof, the drainage groove can also serve as the drainage. The number of members can be reduced.

By including the vertical frame 8 of the adjacent unit and the contact member 25 which is inserted over the vertical frame 8 of the adjacent unit above or below the vertical frame 8 of the adjacent unit, the abutment members 18 abut against each other as described above, thereby causing interlayer displacement. Make the displacement of each unit uniform,
At the same time, since the contact member 25 absorbs the interlayer displacement by the slide in the gap (d) between the vertical frame 8 and the contact member 25 and the deformation of the vertical frame 8, the displacement amount of the unit is equivalent to the slide amount. The amount can be regulated. Therefore, the displacement amount of each unit can be made uniform and regulated to a constant amount, and the seal performance of the joint packing can be maintained very suitably.

When the hitting member 25 is provided, if the lower part thereof is inserted into the vertical frame 8 of the lower adjacent unit without a gap and the upper part is inserted into the vertical frame 8 of the upper adjacent unit with a gap, the hitting member 25 is provided. There is no need to provide a means for preventing the hit 25, and the contact member 25 is easily installed, and the gaps on both sides of the upper part of the hit member 25 are made equal, so that the regulation of the interlayer displacement to each side is made equal.

[0031]

As described above, according to the present invention, the abutting members are installed at the same level on the vertical frames of the adjacent units which are joined to each other, and when the interlayer displacement occurs, the abutting members adjacent to each other are abutted. In this case, since the displacement amount of each unit becomes equal, the joint becomes uniform, and a situation in which some units are largely displaced can be avoided. Therefore, the compressive force and the amount of displacement applied to the joint packing between the respective units become uniform, and the seal performance is preferably maintained. Moreover, the deviation is uniform, which is preferable in terms of design.

If the abutment member is installed at the lower end of the vertical frame and a drainage groove is provided on the upper surface of the vertical frame, the abutment member receives the water descending through the space in the vertical frame and drains it to the outside. Since it can also be used as a means, it has the advantage that it can be used for drainage while preventing variations in joints.

In addition to the abutting member, the unit displacement can be made uniform by including a contact member inserted between the upper and lower vertical frames, and the interlayer displacement can be regulated to a constant value. The seal performance can be maintained very suitably.

With the structure in which the lower part of the hitting material is inserted into the vertical frame of the lower adjacent unit without a gap and the upper part of the hitting material is inserted into the vertical frame of the upper adjacent unit so as to form appropriate gaps on both sides, The material can be installed easily and the interlayer displacement can be regulated appropriately, improving the practicality.
