DETAILED DESCRIPTION OF THE INVENTION

[0001]

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

[0002]

BACKGROUND ART In recent years, a curtain wall unit (sash) has been used as an outer wall of a building. This curtain wall unit is configured by disposing surface materials such as glass and metal panels 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.

[0003] When such a curtain wall unit is attached to a frame such as a cubic, it is usually required to install the curtain wall unit 3-6.
As disclosed in Japanese Patent No. 8219, brackets are attached to the left and right sides of the cubic, and the horizontal frame of the curtain wall unit is fixed to the brackets with bolts.

[0004]

Since the horizontal frame of the curtain wall unit is usually arranged between the vertical frames, when the horizontal frame is fixed in a horizontal manner via the bracket, the bracket is extended to the horizontal frame side. In addition, it is necessary to provide a ridge with a relatively large width, and there is a problem that the width of a mounting portion for fixing the horizontal frame to the ridge is increased. In particular, the bracket supports the load on the curtain wall unit, the wind pressure applied to the unit (indoor and outdoor directions), and the horizontal direction perpendicular to the indoor and outdoor directions (right and left along the wall). Side, the bracket itself had to be relatively large and strong.

[0005] For this reason, there has been a problem that the width of the cubic and the dimensions of the bracket are increased, and the size of the glass portion of the curtain wall unit, that is, the opening area of the window is reduced accordingly. In addition, since the brackets are exposed and conspicuous, there is a problem that the appearance of a cubic or the like deteriorates when the cubic or the like is exposed to the indoor side. On the other hand, when a bracket or the like is covered with a decorative material or the like, there has been a problem that the width of the covering portion becomes large and the opening area of the window becomes smaller. In addition, there is a problem that the work of mounting the decorative material or the like covering the bracket is required, so that the amount of work is increased and the construction period is lengthened.

Also, in order to increase the opening area of the window, it has been required to reduce the width of the cubic itself. However, when the width dimension of the cubic is reduced, the cubic strength is reduced accordingly, and there is a problem that sufficient supporting strength for supporting the curtain wall unit cannot be obtained.

For this reason, it is conceivable to improve the strength by bridging a blind (cross member) between the cubic members. At this time, the blinds are often mounted on a support piece projecting in advance from the side of the cubic and bolted in consideration of the workability at the site. However, in such a structure, since the supporting piece and the blind overlap at the blind end, there is a problem in that the vertical dimension of the joint is increased and the opening area of the window is reduced. In addition, since the joints where the blinds and the support pieces are arranged in an overlapping manner are cluttered, the appearance is deteriorated if the joints are exposed to the indoor side as it is. There is a problem that the opening area of the window becomes smaller as the amount of work increases.

A first object of the present invention is to mount a curtain wall unit in a vertical orientation so that the width 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. It is an object of the present invention to provide a curtain wall unit mounting structure that can reduce the amount of work without the need.

A second object of the present invention is to provide a curtain wall unit which supports a curtain wall unit which can increase the opening area of a window and can reduce the amount of work without having to cover a joint with a decorative material or the like. It is to provide an eye joining structure.

[0010]

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

[0011] According to this structure, the vertical frame, not the horizontal frame, of the curtain wall unit is mounted in an upright manner, and the connecting bracket attached to the outer surface of the vertical frame, that is, the position closest to the upright is used. Since the bracket 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 cubic outdoor surface and the load thereof is supported, the connecting bracket is mounted in the indoor / outdoor direction or the left / right direction of the curtain wall unit. It is only necessary to support only the load applied to the connecting bracket, so that the size of the connecting bracket itself can be reduced accordingly. Furthermore, since the connection bracket is fixed not to the left and right side surfaces of the cubic but to the outdoor surface, it does not protrude from the cubic in the left-right direction.

As described above, the connecting bracket can be made smaller, and the width of the mounting portion of the curtain wall unit on the stake can be reduced as compared with the conventional case. Further, since the connection bracket is mounted on the cubic outdoor surface, it is not exposed to the indoor side, and there is no need to provide a decorative material or the like to cover the mounting portion of the connection bracket or the like. For this reason, the opening area of the window can be increased as compared with the conventional case, and furthermore, a decorative material or the like is not required, and the mounting work is eliminated, so that the work amount can be reduced and the construction period can be shortened.

At this time, when each of the vertical frames of the two curtain walls arranged adjacent to each other is mounted on one side, a connecting bracket is mounted on the outer surface of each vertical frame so that the height position is different. It is preferable that each connecting bracket is fixed to the mounting block, and the vertical frame of the curtain wall unit is mounted vertically. In this case, the connecting brackets can be attached to the vertical frame of each curtain wall unit in advance, and only the work of arranging the curtain wall units and fixing the connecting brackets to the mounting blocks need be performed at the site. Performance can be improved. In addition, 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 attaching the vertical frame of one curtain wall unit, the vertical position of the other curtain wall unit is removed. A frame can also be attached, and each vertical frame can be attached sequentially, so that workability can be improved.

[0014] In the joint structure for supporting the curtain wall unit according to the present invention, the concave portion into which a support piece protruding horizontally from the side surface of the cubic is fitted is provided with a blind hole. It is formed on the lower surface of both ends, and the inner peripheral shape of this recess is
Formed according to the outer peripheral shape of the support piece, and
The support piece is formed in accordance with the thickness dimension of the support piece, the seamless end is placed on the support piece, the support piece is fitted in the concave portion, and the gap between the support piece and the seamless piece is formed. And a gap filled with a filler to seal the gap.

According to such a configuration, the curtain wall unit can be seamlessly stretched between the mountings, so that the required supporting strength can be obtained even if the width of the mounting is reduced, and the curtain wall unit can be used. The area concealed by the cubic is small, and the opening area of the window is large. Moreover,
Because the support piece is fitted and integrated into the seamless recess,
The height of the seamless joint can also be accommodated in the height of only the blind without adding the support pieces. For this reason,
The dimensions of the cubic and seamless joints are reduced, and the opening area of the window can be increased.

Further, if the gap between the supporting piece and the blind is filled with a filler such as iron putty to close the gap, the appearance of the supporting piece and the blind can be integrated to improve the appearance. For this reason, there is no need to cover the joining portion with a decorative material, and the work of attaching the decorative material is not required, thereby reducing the amount of work and shortening the construction period.

Then, by attaching each curtain wall unit 1 to the cubicle 40 sequentially, the wall surface of the building composed of the curtain wall is configured.

According to the present embodiment, when attaching the curtain wall unit 1 to the cubicle 40, the vertical frame 2 is placed on the support block 43, and the connecting bracket attached to the outer surface of the vertical frame 2 is attached. 30 mounting block 4
2, the load of the curtain wall unit 1 can be supported by the support block 43, and the connection bracket 30 is attached to the curtain wall unit 1.
Only the forces in the indoor and outdoor directions and in the left and right directions need to be supported, and the size can be reduced as compared with the conventional bracket. Further, since the connecting bracket 30 connects the vertical frame 2 closest to the cubic 40 and the cubic 40 instead of connecting the cubic 40 and the horizontal frame as in the related art, However, the size of the connection bracket 30 can be reduced, and there is no need to protrude from the cubic 40 in the left-right direction. For this reason, the width dimension of the cubic 40 can be reduced, and there is no need to project the connecting bracket 30 from the cubic 40 in the left-right direction.
Can be reduced in size, and the opening area of the window by the double-glazed glass 6 can be increased accordingly.

The connecting bracket 30 is within the width of the outdoor surface 41 of the cubic 40 and does not protrude to the left and right of the cubic 40.
0, that is, the joint between the curtain wall unit 1 and the cubicle 40 can be hidden by the cubicle 40. Therefore, unlike the related art, there is no need to arrange a decorative material or the like that covers the bracket portion, and the amount of work can be reduced to shorten the construction period, and the decorative material can reduce the opening area of the window. Can be prevented. Further, the joint portion of each curtain wall unit 1 is provided with a primary seal using a backup material 33 and a sealing material 34 and an annular gasket 35.
The connection bracket 30 is not exposed to the outside of the room, and there is no need to provide a decorative material on the outside of the room.

The connecting brackets 30 are attached to the respective vertical frames 2, and the mounting positions on the respective vertical frames 2 are set to be shifted in the vertical direction. It is possible to reduce the number of on-site operations by being attached, and it is possible to install each curtain wall unit 1 irrespective of other adjacent units 1. For this reason, for example, when the number of workers is small, one curtain wall unit 1 can be attached to the cubicle 40, and when there are many workers, a plurality of adjacent curtain wall units 1 can be installed. 40 squares at the same time
Can be installed in various steps, and workability at the time of installation can be improved.

Further, since connecting bolts 47 are provided at the middle part of the vertical frame 2 in the vertical direction to connect the adjacent vertical frames 2 to each other, the vertical frame 2 is fixed to the cubicle 40 at only two upper and lower locations. Even in such a case, it is possible to prevent the middle portion of the vertical frame 2 from being curved by the pressure contact force of each annular gasket 35 to form a gap. For this reason, necessary waterproof performance can be reliably maintained, and only two upper and lower locations need to be attached to the cubicle 40, so that the number of parts can be reduced and the attachment work can be reduced.

Further, the curtain wall unit 1 comprises:
Since the connecting bracket 30 can be bolted to the mounting block 42 while the vertical frame 2 is placed on the support block 43, there is no need to support the load of the curtain wall unit 1 with a crane or the like at the time of bolting. Properties can be further improved.

Since the blinds 50 are bridged between the cubicles 40, the support strength of the cubicles 40 can be improved.
0 can be formed by a thin steel plate. For this reason,
The width of the cubic 40 can be reduced, and the window opening area of the curtain wall unit 1 can be increased accordingly.

When the blind 50 is joined to the cubic 40, the supporting piece 5 is inserted into a fitting recess 55 formed in the blind 50.
Since 1 is inserted, the thickness of the joint between the blind 50 and the support piece 51 is not added to the thickness of the support piece 51, and the height of the blind 50 alone can be set. For this reason, the height dimension of the joint between the cubic 40 and the blind 50 can be reduced, and the opening area of the window can be further increased.

Further, since all gaps and the like generated when the blinds 50 are arranged are filled with the filler 60 and repaired,
The blind 50, the support piece 51, and the cubic 40 can also be made integral in appearance. For this reason, 40
And the design of the blind 50 can be improved.
Since the 0 and the blind 50 can be directly exposed to the indoor side, there is no need to cover and cover the joint with a cosmetic material or the like, so that the amount of work can be reduced and the construction period can be shortened. Can be prevented from becoming small.

The present invention is not limited to the above embodiment. For example, in the above embodiment, when attaching the vertical frame 2 to the cubicle 40, the connecting bracket 30 having a flat L-shape is used. However, the connecting bracket 30 is formed in another shape, for example, a flat U-shape, and is disposed adjacent to the flat bracket. Each vertical frame 2 may be attached to the cubicle 40 by using a connection bracket attached to both side surfaces thereof. However, when two vertical frames 2 are fixed to one connection bracket in this way, at least one of the vertical frames 2 must be joined to the connection bracket at the site, and the on-site work increases and the work efficiency decreases. Therefore, it is preferable to attach the connection bracket 30 to each vertical frame 2 as in the above embodiment.

The mounting structure of the curtain wall unit according to the present invention is not limited to the case where the curtain wall unit is mounted on the cubic 40 with the blind 50 as in the above-described embodiment, but also the cubic cubic formed. It can be used when attaching to various types of cubicles.

Further, in the cubic 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 cubicle 40 via the connecting bracket 30 as in the above embodiment. The present invention can be applied to not only the case where the upper and lower frames 3 and 4 of the curtain wall unit 1 are attached to both left and right sides of the cubicle 40 via the connecting bracket, but also the case where the upper and lower frames are attached.

[0043]

According to the curtain wall unit mounting structure of the present invention, when the curtain wall unit is mounted vertically, the width 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 having to cover the mounting portion with a decorative material or the like.

According to the joining structure for supporting the curtain wall unit according to the present invention, sufficient supporting strength can be obtained even if the width of the supporting member for supporting the curtain wall unit is reduced. The height of the cubic and seamless joints can be reduced, the window opening area can be increased, and the joints need not be covered with a decorative material or the like, and the amount of work can be reduced.
