Description

[Detailed Description of the Invention] Industrial Application Field The present invention relates to a joint device for airtightness and watertightness between each unit of a unit type curtain wall.

Prior Art As shown in Japanese Unexamined Patent Publication No. 56-100953, a pair of horizontal gaskets and a vertical gasket are integrally formed in advance to match the size of rectangular units arranged on the upper, lower, left, and right sides. A joint device is known in which a formed gasket assembly is installed between vertically and horizontally adjacent units to make the spaces between the units airtight and watertight.

Problems to be Solved by the Invention With such a joint device, it is necessary to manufacture gasket assemblies in advance according to the shape and size of the unit, and there is no compatibility, and a large number of gasket assemblies must be manufactured. It requires preparation, labor is required to manufacture it, and the cost is high.

[Means and effects for solving the problem] In a unit type curtain wall in which rectangular frame-shaped units 1 are arranged vertically, horizontally, and horizontally, a cross is formed at the intersection 8 of the crosses of each unit 1 adjacent vertically, horizontally, and horizontally. At the same time, a horizontal gasket 11 is installed between the vertically adjacent units 1 so as to be joined to the cross gasket 10, and a vertical gasket 12 is installed between the left and right adjacent units 1. The cross portion gasket 10 is formed by integrally forming four plate-like bodies 13 in a cross shape, each having a predetermined width and thickness and having sealing portions on both sides in the width direction. A protrusion 16 is integrally formed in the middle part of each plate-like body 13 in the width direction, facing the back side, and a pair of fin pieces 17, 17 are attached to each protrusion 16, respectively, facing in the width direction of the plate-like body 13. The horizontal gasket 11 and the vertical gasket 12 have substantially the same cross-sectional shape as the plate-like body 13, and are butted against the end of the plate-like body 13, and the horizontal and vertical gaskets 11 and 12 are made of the same size as the unit 1. By cutting it according to the size and installing it between the upper and lower, left and right units, it is possible to make the spaces between the upper and lower and left and right adjacent units airtight and watertight, and even if the sizes of the units are different, the same horizontal and vertical gaskets 11 and 12 Since airtightness and watertightness can be achieved by using the cross part gasket 10, it is advantageous in terms of cost, and the sealing part of the plate-shaped body 13 of the cross part gasket 10 and the pair of fin pieces 17, 17 are used to seal between adjacent units vertically and horizontally. Since it is double-sealed, it has excellent airtightness and watertightness.

1 are integrally formed, and a notch 21a having a length l ₁ −α is formed at the end of the pair of fin pieces 21 of the horizontal gasket 11, and a notch 21a having a length of l 1 −α is formed at the lower end of the pair of fin pieces 21 of the vertical gasket 12. A notch 21a having a length of l ₁ −α is formed, and a pair of protrusions 19
And the upper part of the pair of fin pieces 21 has a notch 19a,
21a are formed and are shorter than the upper end surface of the plate-like body 18 by l ₂ −α.

Then, the horizontal gasket 11 and the vertical gasket 12
As shown in FIG. 4 and FIG. As shown in FIG.
A plate-like body 13 is connected to the upper surface of the body 8 so as to overlap with each other. This weight allowance is made larger than the relative displacement amount of the unit 1.
