Description

[0001]
BACKGROUND OF THE INVENTION
The present invention relates to a joint window joint structure and a joint window gasket. More specifically, the present invention relates to a joint part structure including a rubber gasket and a joint seal part formed by filling a sealant.
[0002]
[Prior art]
For example, Japanese Patent Application Laid-Open No. 8-303127 discloses a joint window joint structure in which two or more window plate materials are continuously attached to a window opening of a building and the joints of these window plate materials are sealed. There is something.
[0003]
The joint structure described in the above publication includes a first gasket part that fits and supports one adjacent window plate material, and a second gasket part that fits and supports the other window plate material, The pair of gasket portions are brought into contact with each other and supported by a vertical member, and a water stop seal portion is provided on the contact surface of these gasket portions. The water-stop seal portion is formed by forming a groove portion on the contact surface of the gasket and fitting a seal member made of silicone sponge into the groove portion.
[0004]
In the above prior art, the gasket provided between the adjacent window plate materials is formed by dividing the gasket into a first gasket portion and a second gasket portion. Relative movement in the direction is allowed. For this reason, it becomes possible to absorb the deviation in the thickness direction of the window plate material due to the dimensional accuracy and mounting error of the precast panel provided around the window opening. Moreover, the watertightness between the pair of gasket portions is also maintained by providing the water stop seal portion.
[0005]
[Problems to be solved by the invention]
However, when the displacement of the window plate material is large, it is difficult to absorb the displacement of the window plate material only by the elastic deformation of the gasket as described in the above publication.
[0006]
In order to solve the above problem, it is also conceivable that the upper and lower edges of the window plate material are fixed to the upper and lower edges of the window opening by using a gasket, and the joint portion is configured by filling a seal material between adjacent window plate materials. .
[0007]
However, when sealing is performed by bringing the rubber material constituting the gasket into contact with the filled sealing material, the sealing material filled with compounding ingredients such as the rubber vulcanizing agent and anti-aging agent constituting the gasket is transferred (migration). ), The adhesion performance of the sealing material and the strength after curing are likely to be reduced or discolored.
[0008]
The invention of the present application can absorb the deviation even when the deviation between the window plate materials is large, and even if the gasket and the sealing material are used in combination, the performance of the sealing material is not deteriorated or discolored. It is an object of the present invention to provide a joint joint structure and a continuous window gasket used therefor.
[0009]
[Means for Solving the Problems and Effects of the Invention]
Invention of Claim 1 of this application is the structure of the joint part for continuous windows which supports the window board material provided in a row by the building window opening, and seals the joint between adjacent window board materials, A gasket that fits and supports the upper and lower edge portions of each window plate material along the upper and lower edge portions of the window opening, and a joint seal portion that is formed by filling a seal material between side edge portions of adjacent window plate materials, and A metal plate is integrally joined to the axial end face of the gasket, and the joint seal portion and the gasket are connected via the metal plate.
[0010]
In this invention, since the joint part between adjacent window board | plate materials is sealed by filling a sealing material, even if the shift | offset | difference of a window board | plate material becomes large, it can respond easily.
In particular, by providing the metal plate, the gasket and the filled sealing material do not come into contact with each other. For this reason, there is no possibility that the composition component of the gasket is transferred to the sealing material and the sealing performance or the like of the sealing material is impaired.
[0011]
The metal plate should just be formed so that the sealing material with which the joint seal part was filled may not contact the end surface of a gasket, and should just be formed in the shape which covers a part or all of a gasket end surface.
[0012]
Further, by joining the metal plate integrally at the time of vulcanization molding of the gasket, the joining strength is increased, and the gasket is not peeled off from the metal plate. In addition, it is possible to ensure water stopping performance at the joint interface between the gasket and the metal plate.
[0013]
The material of the metal plate is not particularly limited as long as it can be integrally joined to the gasket. For example, various materials such as an iron plate, an aluminum plate, and a stainless plate can be adopted.
[0014]
The present invention can also be applied to vertically connected windows. That is, the invention described in claim 2 is a structure of a joint portion for a continuous window that supports a window plate material provided in a building window opening in a vertical direction and seals a joint between adjacent window plate materials, A gasket that fits and supports both side edges of each window plate material along both side edges of the window opening, and a joint seal portion that is formed by filling a seal material between the upper and lower edges of adjacent window plate materials, and A metal plate is integrally joined to the axial end face of the gasket, and the joint seal portion and the gasket are connected via the metal plate.
[0015]
In the invention described in claim 4 of the present application, the gasket is provided with a fitting groove for fitting and supporting the edge of the window plate material, and a zipper groove for fitting the zipper, and the zipper is fitted into the zipper groove, The edge portion of the window plate member fitted in the fitting groove is configured to be elastically pressed.
[0016]
By pressing and holding the window plate material with the zipper, the window plate material can be reliably supported by the gasket. Moreover, the watertightness between a gasket and a glass plate is securable. When the portion of the gasket in which the zipper groove is formed is connected to the joint seal portion, it is desirable to join the metal plate to the region including the zipper groove so that the zipper component does not transfer to the filling seal material.
[0017]
DETAILED DESCRIPTION OF THE INVENTION
Hereinafter, embodiments of the present invention will be described with reference to the drawings.
FIG. 1 is a front view of a continuous window structure to which a joint structure according to the present invention is applied. A horizontally long window opening 3 is provided between the upper and lower wall portions 2 and 2 of the building 1, and a plurality of glass plates (window plate materials) 4 are continuously attached to the window opening 3, thereby forming a horizontal continuous window. A structure is formed.
[0018]
As shown in FIG. 2, the glass plate 4 is fixed by a gasket 6 that is fitted and supported by a mounting member 5 provided along the upper and lower edges of the window opening 3. The mounting member 5 is embedded and fixed in the wall 2, and the gasket 6 is fitted and supported by a protrusion 7 having a T-shaped cross section protruding along the window opening.
[0019]
The gasket 6 is formed by extruding rubber such as chloroprene rubber, for example, and as shown in FIG. 5, a fitting groove 8 that fits into the protruding portion 7 and a fitting that fits and supports the plate glass 4. A groove 9, a zipper groove 10 into which a rubber zipper is fitted, and a seal lip 11 that elastically contacts the edge of the window opening are provided.
[0020]
The edge of the plate glass 4 is fitted into the fitting groove 9 and a rubber zipper 12 is fitted into the zipper groove 10 so that a portion in the vicinity of the glass plate is elastically pressed against the side of the glass plate. The upper and lower edges of 4 are supported by the gasket 6 with water tightness.
[0021]
On the other hand, a joint gap formed between adjacent glass plates 4 or gaskets 6 is filled with a sealing material made of silicone sealant to form a joint seal portion 13.
[0022]
As shown in FIG. 4, the joint seal portion 13 is formed by inserting a backup material 15 such as foamed polyethylene into the joint gap and filling the seal material on the surface side.
[0023]
Further, as shown in FIG. 3, the metal plate 14 is integrally joined to the axial end surface of the gasket 6, and the joint seal portion 13 and the gasket 6 are connected via the metal plate 14. Yes.
[0024]
The metal plate 14 is formed using a stainless steel plate, and is formed in a shape that covers almost the entire area of the end face of the gasket 6 as shown by a one-dot chain line in FIG. The metal plate 14 is integrally joined when the gasket 6 is vulcanized.
[0025]
In the embodiment, since the end face of the gasket 6 and the joint seal portion 13 are connected via the metal plate 14, the gasket 6 and the joint seal portion 13 are not in direct contact with each other.
[0026]
Therefore, the vulcanizing agent and anti-aging agent contained in the chloroprene rubber constituting the gasket 6 do not shift to the sealing material constituting the joint seal portion 13. For this reason, there is no possibility that the sealing material is denatured and the sealing performance and the curing characteristics are deteriorated. Moreover, since the sealing performance can be exhibited over a long period of time, the reliability of the joint portion is increased.
[0027]
Further, in the present invention, since the joint portion between the adjacent window plate materials or gaskets is sealed by filling the seal material, it is possible to absorb the attachment error of the window plate material while minimizing the width of the joint portion.
[0028]
The present invention is not limited to the embodiment described above. In the embodiment, a gasket formed from chloroprene rubber is employed, but a gasket formed from another rubber material such as silicone rubber can be employed. The sealing material is not limited to silicone, and other sealing materials such as acrylic can be used. Further, the metal plate is not limited to stainless steel, and other materials such as aluminum can be adopted.
[0029]
Further, the shapes of the gasket and the metal plate are not limited to the embodiment. For example, as shown in FIG. 6, the fitting groove 16 is formed at the edge of the window opening, while the fitting protrusion 18 is formed at the bottom of the gasket 17, and the fitting protrusion 18 is fitted into the fitting groove 16. Thus, the present invention can be applied to a case where the gasket 17 is configured to be fixed to the window opening.
