[Detailed description of the invention]

[0001]

The present invention relates to a mullion type car.
The present invention relates to a glass post-fitting airtight holding mechanism in a ten-wall.

2. Description of the Related Art In recent years, there has been a tendency for high airtightness to be required for curtain walls in accordance with high performance. Conventionally, a mullion type curtain wall is provided with a pressing edge for holding down the glass, and the pressing edge holds down the glass via a seal material filled between the glass and the glass. The pressing edge for holding the glass is in contact with the mullion fixed to the skeleton side. An airtight packing is provided at a contact portion between the pushing edge and the mullion, and the airtight packing seals between the pushing edge and the mullion. Therefore, by sealing between the pushing edge and the mullion, the external pressure side, which is the outdoor side, and the internal pressure side, which is the indoor side, are shut off, so that the airtightness of the curtain wall is maintained. It is becoming.

[0003]

However, since the pressing rim abutting on the mullion side is only pressed from the glass side via the seal material, the airtight packing is sufficiently provided on the mullion side. It cannot be pressed, and in some cases, it is pushed back by the repulsive force of the airtight packing, and a gap is formed in the contact portion between the pressing edge and the mullion, which may cause air leakage.

The present invention has been made in view of the above circumstances, and provides a glass-fitting type airtight holding mechanism capable of fixing a pushing edge and a mullion before glass fitting and suppressing a repulsive force of a gas-tight packing. Accordingly, an object of the present invention is to improve the airtight performance without impairing the appearance.

[0005]

In order to achieve the above-mentioned object, the structure of the glass-fitted airtight holding mechanism according to the present invention is as follows.
The ridge is inside the glass room and on both sides of the mullion support
Provided along the outdoor side and the chamber interior side adapted to be in contact with the Marion air <br/> dense packing of the pressing edge
In a glass back-fitting airtight holding mechanism that shuts off the inside , an L-shaped fitting having a piece parallel to the glass is pressed.
Attachment is made to a support piece of the mullion that passes through the space between the piece of the L-shaped fitting and the glass, and a protruding piece on the outside of the pressing edge parallel to the piece of the L-shaped fitting is attached to the piece of the L-shaped fitting And the boss is tightened with a bolt and the sealing edge is
In close contact with the mullion .

[0006]

When the bolt is tightened, the pushing edge and the mullion are pressed against the repulsive force of the sealing gasket, so that the pushing edge does not separate from the mullion due to the repelling force of the sealing gasket. No air gap is formed between them, and the airtight packing is in a close contact state.

BRIEF DESCRIPTION OF THE DRAWINGS FIG. 1 is a perspective view showing a preferred embodiment of the present invention.
FIG. 1 is a cross-sectional view of a curtain wall showing a glass-fitted airtight holding mechanism according to the present invention. As shown in FIG.
In addition, a pressing edge 3 is provided on the indoor side between the adjacent glass 1 with the joint therebetween , and an end of the glass 1 is provided with a sealing material on the outside contact surface of the pressing edge 3 formed on the left and right. 5 is held down. The glass 1 is of a so-called rear fitting type, which is fitted after the pressing edge 3 is fixed. A mullion 7 is brought into contact with the rear surface of the pressing edge 3 , that is, the indoor side , and
An airtight packing 9 is provided between the indoor side and the mullion 7. Therefore, between the glass 1 on the external pressure side a
The central b portion of the pressing edge 3 is shielded from the outer peripheral c portion of the pressing edge 3 on the inner pressure side by an airtight packing 9.

The mullion 7 has a support piece 1 protruding outside.
1 are formed, and the support piece 11 penetrates between the pressing edges 3 and protrudes outside from joints between the glasses 1. A protruding piece 1 sandwiching a supporting piece 11 is provided at the left and right outdoor contacting end portions of the pressing edge 3.
3 is formed, and the tip of the projecting piece 13 engages with the engaging groove formed in the supporting piece 11 from the outdoor side.

Incidentally, a pair of L
The metal fittings 15 are attached, and each of the L-shaped metal fittings 15 is disposed so that one piece thereof is parallel to the protruding piece 13. L
A bolt 17 is screwed into one piece of the metal fitting 15 and the projection 13, and the bolt 17 fixes the one piece of the L-shaped metal fitting 15 and the projection 13 in the approaching direction. That is, by fixing one piece of the L-shaped bracket 15 and the protruding piece 13, the pressing edge 3 and the mullion 7 are pressed against the repulsive force of the airtight packing 9.

[0010] In the glass rear fitting type airtight holding mechanism configured as described above, before the glass 1 is fitted, the bolt 1
When the sealing member 7 is tightened, the pushing edge 3 and the mullion 7 are pressed against the repulsive force of the hermetic packing 9, so that the pushing edge 3 does not separate from the mullion 7 due to the repelling force of the hermetic packing 9. As a result, a gap does not occur between the pressing edge 3 and the mullion 7, the airtight packing 9 is always in a close contact state, and high airtightness is maintained. Further, since the L-shaped bracket 15 is attached to the support piece 11 of the mullion 7 penetrating between the pressing edges 3 and is not exposed, the hermetic performance can be improved without impairing the appearance.

[0011]

As described above in detail, the glass rear-fitting airtight holding mechanism according to the present invention attaches the L-shaped fitting to the mullion support piece, and attaches one piece of the L-shaped fitting to the outdoor side of the pushing edge.
When the bolt is tightened, the ridge and the mullion are pressed against the repulsive force of the hermetic packing, and the hermetic packing is always in close contact,
The airtight performance can be improved without impairing the appearance.
