Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a curtain wall unit mounting structure and a cubic and seamless joint structure for supporting the curtain wall unit.

[0002]

BACKGROUND ART In recent years, curtain wall units (sashes) have been used as outer walls of buildings. This curtain wall unit is configured by arranging a face material such as glass or a metal panel in a sash frame (frame) in which a vertical frame and a horizontal frame (upper and lower frames) are assembled in a rectangular frame shape.

When such a curtain wall unit is mounted on the side of a body such as a cube, it is usually 3-6
As disclosed in Japanese Patent No. 8219, brackets are attached to both right and left sides of the cube, and the horizontal frame of the curtain wall unit is bolted and fixed to the brackets.

[0004]

By the way, since the horizontal frame of the curtain wall unit is usually disposed between the vertical frames, when the horizontal frame is fixed vertically via the bracket, the bracket is extended to the horizontal frame side. In addition, it is necessary to form the vertical frame having a relatively large width, and there is a problem that the width of the mounting portion for fixing the horizontal frame to the vertical becomes large. In particular, the bracket supports the load of the curtain wall unit, the wind pressure applied to the unit (indoor / outdoor direction), and the horizontal force (horizontal direction along the wall surface) orthogonal to the indoor / outdoor direction. Since it had to be transmitted to the side, the bracket itself had to be relatively large and strong.

Therefore, there has been a problem that the vertical width dimension and the bracket dimension are increased, and the size of the glass portion of the curtain wall unit, that is, the window opening area is reduced accordingly. In addition, since the bracket is exposed and conspicuous, there is a problem in that the appearance of the bracket deteriorates when exposed to the inside of the room. On the other hand, when the bracket or the like is covered with a decorative material or the like, there is a problem that the width dimension of the covering portion becomes large and the opening area of the window becomes smaller. In addition, since it is necessary to attach a decorative material or the like to cover the bracket, there is a problem that the amount of work increases and the construction period becomes long.

Further, in order to increase the opening area of the window, it has been required to reduce the width of the cube itself. However, if the width dimension of the cube is reduced, the strength of the cube is reduced by that amount, and there is a problem that sufficient support strength for supporting the curtain wall unit cannot be obtained.

For this reason, it is conceivable to extend the strength by laying eyes (transverse members) between the cubes. At this time, in general, in consideration of workability at a normal site, the eyes are often bolted by being placed on a support piece which is projected from the vertical side surface in advance. However, in such a structure, since the supporting piece and the seamless eye overlap each other at the blind end, there is a problem that the vertical dimension of the joint portion becomes large and the opening area of the window becomes small. In addition, since the joints where the eyeglasses and the supporting pieces are arranged to overlap each other are cluttered, the appearance will be deteriorated if they are exposed to the inside of the room as they are. There is a problem that the opening area of the window becomes smaller as the work amount increases.

A first object of the present invention is that when the curtain wall unit is mounted vertically, the width dimension of the mounting portion can be reduced, the opening area of the window can be increased, and the mounting portion must be covered with a decorative material or the like. Another object is to provide a mounting structure for a curtain wall unit that can reduce the amount of work.

A second object of the present invention is to support a curtain wall unit which can increase the opening area of the window and can reduce the amount of work without covering the joint portion with a decorative material or the like. It is to provide a joint structure for eyes.

[0010]

SUMMARY OF THE INVENTION The present invention is a mounting structure for vertically mounting a curtain wall unit, wherein a mounting block is fixed to an outdoor surface of a vertical chamber, and the mounting block is mounted on the outdoor surface of the same vertical chamber. The support block is fixed below, the lower end surface of the vertical frame of the curtain wall unit is placed on the support block, and the outer surface of the vertical frame (the surface facing the vertical frame of another curtain wall unit adjacently arranged). ) Is attached to the mounting block via a connecting bracket.

According to such a construction, the vertical frame, not the horizontal frame of the curtain wall unit, is vertically mounted, and the connecting bracket mounted on the outer surface of the vertical frame, that is, the position closest to the vertical frame is used. Since it is fixed vertically, the width of the bracket can be reduced. Further, since the vertical frame of the curtain wall unit is placed on a support block fixed to the outdoor surface of the vertical chamber to support the load thereof, the connecting bracket is used in the indoor / outdoor direction and the left / right direction of the curtain wall unit. Since it suffices to support only the load applied to, the connecting bracket itself can be downsized accordingly. Further, since the connecting bracket is fixed to the outdoor surface, not to the right and left side surfaces of the upright, it does not protrude in the left and right direction from the upright.

As described above, the connecting bracket can be made small, and thus the width dimension of the mounting portion of the curtain wall unit to the upright can be made smaller than the conventional one. Further, since the connecting bracket is attached to the vertical outdoor surface, it is not exposed to the indoor side, and it is not necessary to provide a decorative material or the like to cover the attaching portion of the connecting bracket or the like. For this reason, the opening area of the window can be made larger than in the conventional case, and since the decorative material and the like are not required and the attaching work is eliminated, the work amount can be reduced and the construction period can be shortened.

In this case, when the vertical frames of the two curtain walls arranged adjacent to each other are mounted in one upright position, the connecting brackets are mounted on the outer surfaces of the vertical frames so that the height positions thereof are different from each other. It is preferable to fix each connecting bracket to the mounting block and vertically mount the vertical frame of the curtain wall unit. In this case, the connecting bracket can be attached to the vertical frame of each curtain wall unit in advance, and only the work of arranging the curtain wall unit and fixing the connecting bracket to the mounting block is performed on site. You can improve the property. Also, since the mounting height positions of the connecting brackets are different, the connecting brackets fixed to each vertical frame can be arranged without interfering with each other, and after mounting the vertical frame of one curtain wall unit, A frame can be attached, and each vertical frame can be attached in sequence to improve workability.

Further, in the upright and seamless joint structure for supporting the curtain wall unit of the present invention, the concave portion, into which the support piece projecting in the horizontal direction from the side surface of the upright side is fitted, is formed in a seamless manner. It is formed on the lower surface of both ends, and the endless portion is placed on the support piece, the support piece is fitted in the recess, and the gap between the support piece and the eye is filled with a filling material to close the gap. It is characterized by being joined by.

According to this structure, since the curtain wall unit is mounted on the vertical side without any eye, the necessary supporting strength can be obtained even if the width of the vertical side is reduced, and the curtain wall unit can be installed. The area hidden by the cube becomes smaller and the opening area of the window becomes larger. Moreover,
Since the support piece is fitted and integrated in the blind recess,
As for the height dimension of the seamless joint, the height dimension of only the joint can be accommodated without adding the support piece. For this reason,
The dimensions of the vertical and unlined joints can be reduced, and the opening area of the window can be increased.

Further, if the gap between the support piece and the eyes is filled with a filling material such as iron putty to close the gap, the appearance of the support piece and the eyes can be integrated to improve the appearance. Therefore, it is not necessary to cover the joint portion with the decorative material, the work of attaching the decorative material is unnecessary, the work amount is reduced, and the construction period can be shortened.

Further, annular gaskets 35 are continuously attached to the outer peripheral surfaces of the vertical frame 2, the upper frame 3, and the lower frame 4 for four rounds. These annular gaskets 35 are arranged so as to come into pressure contact with the annular gaskets 35 provided on the outer periphery of other sash frames 5 that are adjacently arranged on the left and right sides or above and below each sash frame 5, and form a secondary seal portion. ing. Then, the double sealing portions of the primary sealing portion and the secondary sealing portion are waterproofed so that rainwater or the like does not enter the indoor side from the joint portion between the sash frames 5.

Now, the upright 40 which supports the sash frame 5 thus constructed is made of a plate-shaped steel material as shown in FIGS. Further, between each cuboid 40 which is separated by a predetermined distance in the left-right direction, a seamless (transverse member) 50 made of a plate-shaped steel material is spanned by a predetermined distance in the vertical direction. Specifically, support pieces 51 are horizontally projected on the left and right side surfaces of the upright 40 by welding. Through holes 52 penetrating in the up-down direction are formed at two locations on each of the support pieces 51. This through hole 52
Nuts 53 are respectively welded to the upper end openings of the.

On the other hand, on the lower surfaces of both ends of the seamless 50, an inner peripheral shape is formed in conformity with the outer peripheral shape of the supporting piece 51, and a vertical depth dimension thereof corresponds to the thickness dimension of the supporting piece 51. The formed recess 55 is formed. In the fitting recess 55, a hole 56 having a size capable of accommodating the nut 53 is provided at a position corresponding to the nut 53 of the support piece 51.
Is formed, and a through hole 58 into which a countersunk screw 57 is fitted is formed in the upper end surface of the hole 56.

Then, from the upper side of the support piece 51, there is no gap 5
0 is placed and the countersunk screw 57 is screwed into the nut 53 from above so that the upright 40 and the blind 50 are inserted through the support piece 51.
Are joined. In addition, the outer peripheral surface of the support piece 51 and the seamless 5
In the clearance between the inner peripheral surface of the fitting recess 55 of 0, the clearance between the edge of the seamless 50 and the upright 40, the upper part of the countersunk screw 57 and the through hole 52 of the support piece 51, a filling material made of iron putty or the like is used. 60 is filled to fill the gap. In addition, these fillers 60
After filling, the unevenness is removed with sandpaper or the like, and a paint is applied if necessary so that each gap or hole is not exposed and is not conspicuous.

In this embodiment as described above, first, the cubic 40 is placed between the floor and the ceiling of the building, and the blind 40 is placed.
Hang between each square 40. At this time, if the support piece 51 is welded to the upright 40 in advance, the unsightly 50 is placed on the support piece 51 and the countersunk screw 57 is screwed into the nut 53 at the site, and the invisible 50 is upright. It is fixed at 40. Then, the gap or the like between the blind 50 and the support piece 51 is repaired with the filler 60.

Next, the vertical frame 2, the upper frame 3, and the lower frame 4 are preliminarily framed, and the multi-layer glass 6 is arranged to form the curtain wall unit 1. Further, the vertical frame 2 is connected to the connecting bracket 30.
Is attached. Then, the vertical frame 2 is placed on the support block 43 of the upright 40, and the connecting bracket 30 is bolted to the mounting block 42 to be mounted. Then, by attaching each curtain wall unit 1 to the vertical 40 in sequence, the wall surface of the building composed of the curtain wall is constructed.

According to the present embodiment as described above, when the curtain wall unit 1 is attached to the upright 40, the vertical frame 2 is placed on the support block 43 and is attached to the outer surface of the vertical frame 2. 30 for mounting block 4
Since the curtain wall unit 1 is fixed to the curtain wall unit 1 by the bolts 46, the load of the curtain wall unit 1 can be supported by the support block 43.
Since it is only necessary to support the indoor / outdoor direction and the lateral force, the size can be reduced as compared with the conventional bracket. Further, the connecting bracket 30 does not connect the upright 40 and the horizontal frame as in the conventional case, but connects the vertical frame 2 closest to the upright 40 and the upright 40. However, the size of the connecting bracket 30 can be reduced, and it is not necessary to project the connecting bracket 30 in the left-right direction from the upright 40. Therefore, the width dimension of the upright 40 can be reduced, and it is not necessary to project the connecting bracket 30 from the upright 40 in the left-right direction.
The size of the joint can be reduced, and the window area of the double-glazing unit 6 can be increased accordingly.

Further, since the connecting bracket 30 is accommodated within the width dimension of the outdoor surface 41 of the upright 40 and does not project to the left and right of the upright 40, the connecting bracket 3 from the indoor side.
0, that is, the joint portion between the curtain wall unit 1 and the upright 40 can be hidden by the upright 40. Therefore, unlike the prior art, it is not necessary to arrange a decorative material or the like for covering the bracket portion, the work amount can be reduced, the construction period can be shortened, and the decorative material can reduce the opening area of the window. It can be prevented. Further, the joint portion of each curtain wall unit 1 includes a backup material 33, a primary seal by a sealing material 34, and an annular gasket 35.
Since it is closed by the secondary seal of No. 3, the connecting bracket 30 is not exposed to the outside of the room, and it is not necessary to provide a cosmetic material on the outside of the room.

Since the connecting brackets 30 are attached to the respective vertical frames 2 and the mounting positions of the connecting brackets 30 are vertically shifted, the connecting brackets 30 are attached to the respective vertical frames 2 in advance. The curtain wall units 1 can be installed so that the work on site can be reduced, and each curtain wall unit 1 can be installed independently of the other adjacent units 1. Therefore, for example, when the number of workers is small, each curtain wall unit 1 can be attached to the upright 40, and when there are many workers, a plurality of adjacent curtain wall units 1 can be installed. At the same time 40
It can also be attached to, and can be installed by various procedures, and workability at the time of attachment can be improved.

Further, since a connecting bolt 47 is provided in the vertical middle portion of the vertical frame 2 to connect the adjacent vertical frames 2 to each other, the vertical frame 2 is fixed to the upright 40 only at two upper and lower positions. Even in such a case, it is possible to prevent the intermediate portion of the vertical frame 2 from being curved due to the pressure contact force of each annular gasket 35 to form a gap. For this reason, the required waterproof performance can be reliably maintained, and the number of parts to be attached to the upright 40 can be reduced because the number of attachment points to the upright 40 is only two in the upper and lower portions, and the attachment work can be reduced.

Furthermore, the curtain wall unit 1 is
Since the connecting bracket 30 can be bolted to the mounting block 42 in a state where the vertical frame 2 is placed on the support block 43, it is not necessary to support the load of the curtain wall unit 1 with a crane or the like when bolting, and the mounting work can be performed. The property can be further improved.

Since the blind 50 is bridged between the stands 40, the supporting strength of the stands 40 can be improved.
0 can be formed of a thin steel plate. For this reason,
The width of the upright 40 can be reduced, and the window opening area of the curtain wall unit 1 can be increased accordingly.

Further, when joining the blind 50 to the upright 40, the supporting piece 5 is placed in the fitting recess 55 formed in the blind 50.
Since 1 is inserted, the thickness dimension of the joint portion of the seamless piece 50 and the supporting piece 51 does not add the portion of the supporting piece 51, and the height dimension of only the seamless piece 50 can be set. Therefore, the height dimension of the joint portion between the upright 40 and the blind 50 can be reduced, and the opening area of the window can be increased.

Further, since the gaps and the like generated when the seamless 50 is arranged are all filled with the filler 60 for repair,
The blind 50, the support piece 51, and the upright 40 can be integrated in appearance. Therefore, the cube 40
And the design of the seamless 50 can be improved.
Since it is also possible to expose the 0 and the blind 50 to the inside of the room as it is, it is not necessary to cover the joint portion with a decorative material or the like, the work amount can be reduced, and the construction period can be shortened. It is possible to prevent the opening area of the device from becoming smaller.

The present invention is not limited to the above embodiment. For example, in the above-described embodiment, when the vertical frame 2 is attached to the upright 40, the planar L-shaped connecting bracket 30 is used, but it is formed in another shape, for example, a planar U-shaped, and arranged adjacently. Each vertical frame 2 may be attached to the upright 40 using connecting brackets attached to both sides thereof. However, when fixing the two vertical frames 2 to one connecting bracket in this way, at least one of the vertical frames 2 must be joined to the connecting bracket on site, and the site work increases and the work efficiency decreases. Therefore, it is preferable to attach the connecting bracket 30 to each vertical frame 2 as in the above-described embodiment.

Further, the curtain wall unit mounting structure of the present invention is not limited to the case where the curtain wall unit is mounted on the upright 40 on which the seamless 50 is hung, as in the above-described embodiment, but the upright which is formed in a tubular shape or the like. It can be used to attach to various types of uprights.

Further, in the vertical and seamless joint structure of the present invention, the vertical frame 2 of the curtain wall unit 1 is attached to the outdoor surface 41 of the vertical 40 via the connecting bracket 30 as in the above-described embodiment. The present invention can be applied not only to the above case, but also to the case where the upper and lower frames 3 and 4 of the curtain wall unit 1 are attached to the left and right side surfaces of the upright 40 via connecting brackets.

[0043]

According to the curtain wall unit mounting structure of the present invention as described above, when the curtain wall unit is mounted vertically, the width dimension of the mounting portion can be reduced, and the opening area of the window can be increased. The amount of work can be reduced without the need to cover the mounting portion with a decorative material or the like.

Further, according to the structure for joining the curtain wall unit supporting the curtain wall unit and the seamless structure, sufficient supporting strength can be obtained even if the width dimension of the curtain wall unit supporting the curtain wall unit is reduced. In addition, the height of the vertical and seamless joints can be reduced, the opening area of the window can be increased, and the amount of work can be reduced without having to cover the joints with a decorative material or the like.
