JPS5942411Y2 - Airtight structure between mullions and mullions in curtain wall - Google Patents

Description

[Detailed description of the invention] This invention is a curtain wall that forms a framework with mullions and mumu (horizontal frames placed between the mullions of the curtain wall), and outside air pressure is connected to the inside of the curtain wall. The equal-pressure space inside the curtain wall and the interior part of the curtain wall are fully applied to the equal-pressure principle of the so-called open joint method, which ensures the watertightness of the curtain wall by creating an equal-pressure space. Regarding the air-tight structure between the two, this design was designed to improve the air-tightness between the mullion and the mullion.

There has been a concept of a so-called open-joint type curtain wall that applies the equal pressure principle, and a mullion type curtain wall in which the entire framework is formed by mullions and non-seamed parts.

It is a space with equal pressure to the outside air (an outside air inlet is provided on the outside side) between the mullioned buttons and the mullions around the four sides of the facing material (panel such as glass, opening/closing window, or its frame) fitted in the framework. However, in order to maintain airtightness between these spaces and the interior parts, especially at the connection between the mullion and the mullion, the mullion is simply fixed to the bracket attached to the mullion. Because the button was only connected, airtightness was not maintained sufficiently and the button did not press, resulting in pressure leakage from the connection and a decrease in watertight performance.

This idea was developed to eliminate the drawbacks of conventional structures of this type.
An airtight gasket is interposed between the open interior surface and the mullion,
By drawing the mullion and the mullions together, the airtight backing is completely sandwiched between them, ensuring complete airtightness and improving watertightness.

Next, this invention will be explained according to the embodiments shown in the drawings.

1 is a horizontal sectional view of the mullion part, and FIG. 2 is a sectional view taken along the line ■-■. It consists of members 2a and 2b.

3 is a surface material (glass). 4.4.5 is a space with the same pressure as the outside air, and this can be achieved by completely introducing outside air from the outside air inlet 8.9, which is partially cut out in the ridge 6, the mullion auxiliary material 7, and the mullion 2. These spaces 4, 4.5 are brought to the same pressure as the outside air.

10 is a bracket for attaching the mullion 1 to the mullion 1, and 11 is formed into an approximately L-shape with a portion extending along the mullion 2 and a portion extending toward the indoor side of the mullion 10. A pulling hardware, 12 is a bolt that is passed through the part of the pulling hardware 11 along the opening 2, 13 is a groove in which the base of the bolt 12 is held, and 14 is a slot for the bolt 12.
A nut 15 screwed into the mullion 1 is a packing that engages with a pocket 16 formed in the mullion 1.

When attaching the mullion 2 to the mullion 1, adjust and fix the entire vertical position of the bracket 10 to the mullion 1, place the mullion 2 on the bracket 10 between the mullions 1, and in this case, the mullion 2
At the end of the groove 13, a gasket 17 (FIG. 4) is fitted and peeled off at a position where it will come into contact with the gasket 15 attached to the mullion 1.

This packing 17 prevents air from leaking from the groove 13.

Next, hook the hook part 19.20 provided at the end of the part of the pulling hardware 11 that extends toward the indoor side of the mullion 10 onto the locking part 18.18' protruding from the mullion 1 (Fig. 3). .

In this case, the bolt 12 is also passed through the hole 21 provided in the pull hardware 11.

A pulling allowance is formed in advance between the inner side surface of the metal fitting 11 and the inner side of the no-mume 2.

By tightening the nut 14 screwed into the bolt 12 in such a state, the inner side surface of the nozzle 20 is pressed against the airtight packing 15.

That is, this packing 15 is compressed by being sandwiched between the mullion 2 and the mullion 1.

22 is a sound prevention material made of, for example, tetrafluorocarbon resin;
This is to completely eliminate the sound generated when the pulling hardware 11 and the blind 2 come into direct contact and a shift occurs between the metal hardware 11 and the blind 2 due to thermal expansion and contraction of the material.

Also, between the rim 6 and the mullion 1, the rim 6 is crimped to the packing 15, and the rim 6 and the mullion 2 are crimped to the packing 15.
3.24 is kept airtight by compressing it.

The above-mentioned structure of this invention greatly contributes to improving the airtightness between the equal pressure space in the curtain wall and the indoor area, especially between the mullions and the mullions.
