Description

[Detailed Description of the Invention] [Industrial Application Field] This invention relates to a glass panel attachment part for a corner part of a horizontal window in a building structure, and is particularly applicable to a curtain wall window using a precast panel on the outer wall. Are suitable.

[Conventional technology]

For example, there are windows shown in FIGS. 10 and 11 as common horizontal windows in building construction. In this example, a sash 43 framed in a rectangular shape by upper and lower frames and left and right vertical frames or mullions is built into the opening between the upper and lower precast panels 41 constituting the curtain wall.

In this case, the satsushi 43
They had to escape through the clearance between the joints. In addition, in the corners of such buildings where displacement during an earthquake is concentrated, it is conventional to form deep grooves in the corner mullions to absorb the displacement, or to create separate mullions in two intersecting directions. Efforts have been made to provide clearances to prevent mutual interference.

[Problem that the invention seeks to solve]

However, in the above-mentioned continuous window, the lines of the sash 43 are thick and overlap many times in appearance, and furthermore, a large clearance is required for the mullions at the corner position, so that the window does not look neat.

In order to solve this problem, it is desirable to have a structure in which the mullions do not appear on the surface of the continuous windows, and in which no mullions or large joints are provided at the corner positions. The problem is whether to follow the interlayer displacement.

This invention aims to solve the above-mentioned problems.

[Means for solving problems]

In the corner glass panel mounting portion of the continuous window of the present invention, an L-shaped glass panel 2 having an L-shaped cross section is mounted between the upper and lower frames 6a and 6b bent in an L-shape at the corner. Upper and lower frames 6a, 6
Regarding the mullions between b, no mullions are provided at the corner positions that are the bent tops, and mullions 4 are provided at both end positions of the L-shaped glass panel 2 at a predetermined interval.

Elastic support members 8 made of synthetic rubber or the like are attached to each of the mullions 4 along the longitudinal direction to elastically support both side edges of the L-shaped glass panel 2 and to absorb displacement during an earthquake. It's getting old.

Further, the upper and lower ends 2a and 2b of the bent top of the L-shaped glass panel 2 are supported via locking elastic blocks 9 attached to the upper and lower frames 6a and 6b.
As shown in FIG. 1, in response to interlayer displacement, the locking elastic block 9 is deformed to prevent damage by locking the layer (displacement is exaggerated in the figure for better understanding).

Note that the L-shaped glass panel 2 is not limited to a homogeneous integrally formed one, and the sealing material 16 at the bent top part
Accordingly, it is also possible to integrate two glass panels.

〔Example〕

Next, the illustrated embodiment will be explained.

FIG. 2 shows an overview of the building, and FIGS. 5 to 7 show an outline of the structure of the building, in which horizontal windows are formed between precast panels 1 that make up the outer wall of the building. The precast panel 1 in this embodiment is made of concrete, and is fixed to a floor slab 32 of a building frame via fasteners 34 and 35 to constitute a curtain wall.

An upper frame 6a and a lower frame 6b constituting the window frame are attached to the lower end surface of the upper precast panel 1 and the upper end surface of the lower precast panel 1, respectively. In addition, these upper and lower frames 6a, 6b
The on-site work can be simplified by driving them into one piece in advance when manufacturing the precast panel 1.

Moreover, each mullion 4, 5 is located inside the indoor side surface of the glass panels 2, 3, so that the mullions 4, 5 do not appear on the outside surface of the window room. These mullions 4, 5 are attached to brackets 23 provided at the lower end of the upper precast panel 1 and at the upper end of the lower precast panel 1, for example in the manner shown by broken lines in FIGS. 8 and 9. It is attached with bolt 24.

In addition, as a decorative material on the indoor side of mullions 4 and 5,
A mullion cover 11 is provided, and a sealing material 25 is filled inside.

With the above-described configuration, the glass panel 3 slides within the upper and lower frames 6a and 6b against interlayer displacement during an earthquake, and the sealant 1 between the glass panels 3
8 deforms to some extent and has the function of suppressing the amount of displacement. In addition, regarding the relationship between the mullion 5 and the glass panel 3, the indoor side surface of the glass panel 3 is adhered to the outdoor side surface of the mullion 5 with a sealant 19, and
A sealant 15 is filled between the upper frames 6a, 6b and the glass panels 2, 3, and the glass panels 2, 3 are sealed.
is fixed.

As shown in FIG. 4, the L-shaped glass panel 2 at the corner is made by abutting two glass panels at right angles and bonding them together with a sealant 16, with both edges extending along the longitudinal direction of the mullion 4. It is supported by the attached elastic support member 8. Elastic support member 8
is made of highly elastic synthetic rubber such as silicone rubber, aluminum profile, plastic, wood, etc., and a sealing material 14 is filled between it and the side edge of the L-shaped glass panel 3.

The upper and lower ends 2a of the bent top of the L-shaped glass panel 2,
2b is supported by locking elastic blocks 9 provided within the upper and lower frames 6a and 6b. The locking elastic block 9 is made of synthetic rubber such as EPT (ethylene propane terprimer), and the locking elastic block 9 is rotated by elastic deformation rather than sliding the L-shaped glass panel 2 against interlayer displacement. Locking is performed at the center to prevent damage to the L-shaped glass panel 2.

[Effects of the invention] L-shaped glass panels are used in the consecutive window corners,
Since there is no mullion in between, the corners, where mullions and joint clearances were previously visible, now have a clean appearance.

The L-shaped glass panel locks around the locking elastic blocks at the upper and lower ends of the bent top, even in cases where sliding is unable to deal with inter-story displacement during an earthquake that concentrates at corner locations, and there is a risk of damage. You can run away.

Since both side edges of the L-shaped glass panel 2 are supported by elastic support members 8 attached along the longitudinal direction of the mullion, it is possible to follow the sliding of other glass panels and the locking of the L-shaped glass panel.
