Description

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

[Conventional technology]

For example, there are windows shown in FIG. 10 and FIG. 11 as a typical set-in transverse window in pill architecture.

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 lateral force at the time of an earthquake will be escaped by the clearance of the width of the joint 44 between the sashes 43. In addition, for the corners of such buildings where displacement during an earthquake is concentrated, conventionally, deep grooves are formed in the corner mullions to absorb the displacement, or separate mullions are formed 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 windows, the appearance is 43mm.
The lines are thick and overlap many times, and the mullion requires a large rear clearance at the corners, which does not give it a clean look.

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 question is whether to follow the displacement between the eyebrows.

This invention aims to solve the above-mentioned problems.

[Failure to solve the problem]

In the glass panel mounting portion at the corner of the continuous window of the present invention, the upper and lower frames 5a are bent in an L-shape at the corner,
An L-shaped glass panel 2 having an L-shaped cross section is attached between 6b. Upper and lower frames 5a.

Regarding the mullions between 6b, 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 in the longitudinal direction to elastically support both side edges of the rectangular glass panel 2 and absorb displacement during an earthquake. It looks like this.

In addition, the upper and lower ends 2a of the bent top of the L-shaped glass panel 2,
2b is supported via locking elastic blocks 9 attached to the upper and lower frames 5a and 6b, and as shown in FIG. (The figure emphasizes the displacement for understanding.)
.

Note that the L-shaped glass panel 2 is not limited to one formed into a homogeneous integral piece, and may be one in which two glass panels are integrated by a sealing material 16 at the bent top.

〔Example〕

Next, the illustrated embodiment will be described.

FIG. 2 shows an overview of the building, and FIGS. 6 and 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 l in this example is made of concrete and is fixed to the floor slab 32 of the building frame via fasteners 34, 35, forming a curtain wall.

The upper frame 6a and the lower frame 6b constituting the window frame are each
It is attached to the lower end surface of the upper precast panel 1 and the upper end surface of the lower precast panel 1. Note that these upper and lower frames 6a.

By driving 6b into one piece in advance when manufacturing the precast panel 1, on-site work can be simplified.

Moreover, each mullion 4, 5 is located inside the indoor side surface of the glass panels 2, 3, so that the mullion 4.5 does not appear on the outside surface of the window room. These mullions 4, 5 are secured by bolts 24 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 installed with.

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

With the above-mentioned configuration, against inter-story displacement during earthquakes,
The glass panel 3 slides within the upper and lower frames 6a and 6b, and the sealant 18 between the glass panels 3 is deformed to some extent.
It 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,
Further, a sealing material 15 is filled between the upper frames 6a, 6b and the glass panels 2.3 to fix the glass panels 2, 3.

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. The 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.

Upper and lower ends 2 a + 2 b of the bent top of the L-shaped glass panel 2
are supported by locking elastic blocks 9 provided within the upper and lower frames 5a and 5b. The locking elastic block 9 is made of synthetic rubber such as EPT (ethylene propane turbimer), 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.

〔Effect of the invention〕

■ L-shaped glass panels are used in the corner sections of the continuous windows, and there are no mullions in between, so the corner sections, where mullions and joint clearances were previously visible, now have a clean appearance.

■ In cases where sliding is unable to deal with interstory displacement during an earthquake that concentrates at corner locations, and there is a risk of breakage, the L-shaped glass panel can be moved around the locking elastic blocks at the top and bottom of the bent top. You can rock and run away.

■ Both edges of the L-shaped glass panel 2 are supported by elastic support members 8 attached along the longitudinal direction of the mullion, so it can follow the sliding of other glass panels and the locking of the L-shaped glass panel. .
